System of dispatching and monitoring of engineering systems. Design of automation and dispatching systems III.1.7 Air conditioning automation

The creation of dispatching systems is one of the key activities of NORVIX-TECHNOLOGY.

The dispatching system is a complex of software and hardware tools that allows remote control of the engineering systems of one or more objects.

An automated dispatch control system (ASCS) is necessary to control engineering equipment that is geographically dispersed, as well as located in hard-to-reach places. As a rule, dispatching is included in the management system of multifunctional facilities with complex engineering infrastructure, such as office buildings, shopping and entertainment centers, as well as industrial complexes and other industrial enterprises.

The following subsystems can be included in the dispatching system:

• power supply, gas supply;
• heat and water supply, accounting of energy resources;
• security and fire alarm systems, fire extinguishing and smoke removal systems;
• Ventilation and air conditioning;
• video surveillance, access control and management;
• lift facilities and others.

The essence of the design of dispatching systems is to solve the problem of visualizing information about the functioning of engineering systems and providing the operator with the ability to directly control the equipment from the control room. Data on the state of engineering equipment is received from local automation controllers and transmitted to the server. The processed technological data with the necessary analytical information is sent to the dispatching server and displayed on the computer screens at the operators' workplaces in a visual dynamic graphical form.

Advantages of the monitoring system of engineering systems of structures

The data received and processed by the dispatching system is formed into messages of various types, which are archived in long-term storage. Based on this information, available at any time, reports are generated.

The dispatching system provides key advantages in facility management:

• constant centralized control of engineering systems;
• rapid response in emergency situations;
• reducing the influence of the human factor;
• optimization of document flow, reporting systems.

NORVIX-TECHNOLOGY implements dispatching projects of varying degrees of complexity.

Along with conventional systems, the company offers dispatch systems with 3D visualization based on the new generation solution GENESIS64. This is a qualitatively new level of dispatcher monitoring capabilities, which allows the operator to see a realistic image of the object with all the parameters associated with specific nodes. The dispatcher can interactively change the detail of rendered objects by removing elements of buildings, installations and viewing them from the inside. Three-dimensional visualization will allow virtual navigation through the depicted objects, offers animation tools and dynamics of three-dimensional images and other advantages of 3D technologies.

Another pride of the company's employees is the ability to design and implement large-scale geographically distributed dispatching systems that provide not only data collection from remote objects, but also distributed computing, multi-level archiving and redundancy.

And a set of project library elements that implement typical housing and communal services facilities make it possible to “assemble” dispatching systems from ready-made components. This development allows you to dramatically simplify the creation of projects and reduce the time of their development by an order of magnitude.

The cost and timing of the implementation of dispatching projects are increasingly influencing the decision-making on the choice of tools for their implementation. Extra costs are especially painful in a situation of general sequestration of budgets, and deadlines are sometimes missed for the same reason - funds are allocated late to purchase equipment and pay for work. It's no secret that in recent years, a significant part of the costs in most projects has been paid to developers. There are few specialists, they are not very cheap. In such a situation, the temptation to use specialized systems is great. But everyone who has tried to follow this path is already aware that it leads to a too rigid system that does not fully take into account local characteristics and needs. As a result, the effect of its implementation is largely reduced to nothing. So what to do, spend the scarce and expensive forces of developers and create a system from scratch based on a universal SCADA system?

Fortunately, there is a golden mean. It is offered on the basis of its system, which is widespread in housing and communal services throughout the Russian Federation, and a set of typical project elements. is based on an object ideology, therefore each such element of the project fully implements a typical housing and communal services object, including a list of interrogated and controlled parameters, their archives and messages, processing algorithms and mnemonic diagrams, control windows and reports, parameter change graphs and event logs.

Among the typical objects:

Individual heat points (ITP);

gas control points;

Pumping stations of all types (water, sewer, fire, storm);

Ventilation installations;

Transformer substations;

Reserve power supply (ATS and DGU);

Apartment and house accounting of resources.

Along with the library of housing and communal services, there is also a complete set of project elements necessary for the creation of ASKUE (ASKUE, AIIS KUE): these are all required reporting forms, as well as OPC servers for most common types of meters, for example, Mercury, SET-4 and others

How is a project created from library type objects?

For "specialized" systems (only ventilation units or only ITP), the project can be simply generated. To do this, you must specify the code of the equipment composition. The idea was borrowed from the SM Constructor software product, with the help of which the Segnetics company (St. Petersburg) configures its controllers to control ventilation units and ITP. But if the code there is the result of a configuration that can be immediately entered into, then when using other types of controllers, such as Regin, you need to tick the checklist in the Excel file. They are automatically summed up and give the desired code. On the basis of this code, not only the composition of the project and the connections of design objects with installed controllers are formed, but also the appearance of equipment mimic diagrams - unused elements are simply disabled from the user interface. Typical objects of ventilation units or ITP can be supplied in an open (with the possibility of editing them) or closed form. In the latter case, only "terminals" of objects are available to establish connections with the equipment.

For apartment-based resource accounting systems that practically do not require customization of their composition, a different approach is used. The project includes the objects "house", "entrance", "floor", "apartments", as well as a script (script) that must be run in development mode after the number of entrances, floors and apartments on the floor is set for each house . The project, including an overview mimic providing home navigation, will be generated fully automatically. It is important to note that the script itself (in C#) is available in the editor built into the integrated environment in a completely open form and can be modified to take into account the specifics of a particular project.

Now consider the case when the project has objects of various types. Each of them is inserted from the library as a whole. In order to implement the project, it remains to perform two operations: binding to equipment and reproduction of an object of this type in the required quantities. Binding does not cause problems even for novice "automators". The fact is that the already mentioned mechanism of “terminals” of objects is understandable on an intuitive level, and dragging the inputs / outputs of controllers to these terminals is a matter of several minutes. But this is a few minutes per object. What if there are many? If the objects are typical, it will be enough to spend just a couple of extra minutes to activate the mechanism of called objects. The project will still have one exemplary object of this type, but after setting the number of its instances, their list and links of each instance to the equipment will be automatically generated. Of course, you can then rename a specific instance or change its links manually if necessary. In runtime, it will be possible to call the document of an individual instance from their complete list.

We have considered the situation with strictly uniform objects. What to do in a situation where they have some differences? In this case, another mechanism comes to the rescue - an instance template. A typical library element acts as a template, and copies reproduced in the project exactly repeat it without losing connection with the original. We can edit any of them, view all the differences between the instances and the template, and when the template changes, apply these changes to all or selected instances.

Rice. Synchronizing objects with a template

How, in the case of objects of different types, is an overview, as a rule, a starting mnemonic scheme created? In this case, it's probably not practical to write a "one-time" script. provides the project developer with a choice of two main mechanisms - the object button and the object symbol. The design object is simply dragged onto the overview mnemonic diagram, and at the choice of the developer, either a button is created with a compressed static image of the mnemonic diagram of the object, or an image with data belonging to a particular instance is “pasted” - a symbol of a typical object created by its author. In both cases, in addition to the visual representation of the object, it is possible to call up its mnemonic diagram or any other document available for the object, such as a message log or a resource consumption report, by clicking on a button or symbol.

Our company has developed a project with automation, dispatching and monitoring systems for ADCS for data centers.

I.1. Automation, dispatching and monitoring systems

I.1.1. Dispatch and control system

The construction of an automated dispatch control system for data centers is supposed to be carried out on equipment with a multi-level hierarchical structure. For each data center, it is planned to build its own dedicated system.

The upper level of the ADCS system is built on the basis of a server with a RAID disk array that supports hot swapping of hard disks. The software (software) must perform the functions of obtaining information about the status and parameters of engineering systems equipment, processing the received data and monitoring, managing from dispatchers workstations, documenting, archiving and storing information, reports and additional solutions for maintenance planning, control and calculation of energy consumption, call center, investment planning. The software must be able to use integration with any local management systems due to excellent support for open technologies (eg "OPC", SNMP).

The ADCS and integrated security systems should ensure the integration of these systems. The servers are placed in a 19” rack in the cross room of each data center.

Dispatcher workstations are located in the control room of the data center. The number and purpose of workstations is determined at the design stage. The recommended number of operators of one shift is 3 people, workplaces - 4:

· Workstation of the shift manager;

· Mechanical systems dispatcher workstation;

· Workstation of electrical systems dispatcher;

· Backup dispatcher workstation.

Each workplace is equipped with one to three monitors with a diagonal of 21 "and loudspeakers for notification. The control room houses printers for preparing reports and a workplace for working with documentation.

At the upper level of the ADCS, the data transmission network is a high-speed network 10/100/1000 Mb/s TCP/IP. The network is organized on the basis of Ethernet switches. The central switch is located in the cross-connect data center in a 19” mounting cabinet. Network gateways L-IP, FieldServer contain means of organizing an independent exchange of information between dispatching workstations (based on a local area network) and field controllers (based on a field bus).

The concept provides for the use of controllers and input/output modules with an open exchange protocol.

Dispatching is provided for engineering systems intended only for the operation of data centers:

general exchange supply and exhaust ventilation of technical premises;

refrigeration machines;

· electricity quality meters on input and main outgoing lines of input-distribution boards;

uninterruptible power supplies;

pumping station of the cold supply system;

· air-conditioning system for turbine halls and auxiliary premises;

pumping drainage sewerage;

lighting control system

and is carried out by collecting the full amount of information from local controllers and automation modules.

Collection of information from the system for monitoring the state of installation cabinets, the air conditioning system for machine rooms, and the leakage control system is carried out according to the protocol.

Monitoring of engineering equipment included in the volume of the main complex:

· system of smoke removal and air overpressure;

· heating system;

· General ventilation systems for warehouses, corridors, control rooms, etc.

diesel generators;

high voltage substations

performed by connecting the local automation controllers of this equipment to the dispatch field bus.

Dispatching of electrical switchboards (ASU, SCBE) is carried out by receiving signals from additional contacts of circuit breakers by input discrete modules and controllers. Modules and controllers are placed in a separate cabinet in close proximity to electrical panels.

Integration with the fire alarm system is carried out at the top level of the systems, each fire alarm panel is connected to the field network using an internal protocol.

Heat and water consumption metering units are installed directly at the entrance to the data center area and are equipped with an interface for connecting to the ADCS system.

III.1.2 Monitoring system for engineering equipment of turbine halls

To organize the management of data center physical infrastructure equipment, it is planned to use Nexans LANsense with an additional EMAC (Environmental Monitoring and Access Control) complex. The system serves as a centralized repository of the most important data on the state of power supply equipment, air conditioning and environmental climate control. Through this system, all data that is recorded by a device connected to the network can be accessed:

In power distribution cabinets (PDUs), these parameters will be: voltage, current of each outgoing power line, state of circuit breakers;

For cooling systems - the cooling capacity of air conditioners, refrigerant temperature, fan speed, temperature and humidity of incoming / exhaust air, the presence of leaks, and other data received from the internal sensors of the air conditioner;

For environmental control systems - temperature, humidity;

Organization of access control to active equipment in server cabinets;

Status of sensors for opening/closing doors of equipment racks.

Also, this solution monitors the health of equipment in real time, provides the ability to generate reports of arbitrary form.

III.1.3 Automation of general ventilation systems

Supply and exhaust systems are equipped with controls, blocking, regulation and control that provide:

Local control from ventilation chambers;

Remote control from the control room;

Automatic blocking of all elements of process equipment included in the system;

Protection of air heaters from freezing according to the air temperature behind the heater and the temperature of the "reverse" heat carrier;

Preheating of the air heater before turning on the supply fan.

To control the temperature and humidity of the air, temperature and humidity sensors are installed in the supply air duct. In this case, temperature regulation is provided by changing the heat output of the air heater by acting on the control valve on the heat carrier. Technological control over the parameters of the coolant is carried out by local indicating devices. In the event of a fire, all general ventilation systems are switched off. Automation equipment is installed in metal shields in the premises of the ventilation chamber. Automatic control is implemented on the basis of freely programmable controllers.

III.1.4 Automation of refrigeration supply

The automation system of the refrigeration pumping station provides for control panels: one panel for controlling the external circuit, the second - for the circuit of refrigeration machines to the consumer. Control panels are located in the room of refrigerating machines and are equipped with signaling and manual control elements. Automatic control is implemented on the basis of freely programmable controllers and expansion modules.

The operation of refrigeration systems is offered in two versions:

The main one is the discharge of heat into the Neva,

An alternative is to release heat into the atmosphere through dry cooling towers.

In the basic version, the automation system operates in two modes - summer and winter:

In winter mode, the system controls the performance of the internal circuit pumps and, through control valves, regulates the amount of water passing through the precision air conditioners;

In summer mode, compared to winter mode, the automation system additionally controls the operation of chillers (controls the performance of chillers, performs protective functions, automatically detects the transition of the system from winter to summer mode).

Alternatively, the system also operates in two modes: summer and winter. In winter mode, controls the operation of freecooling: maintains the glycol temperature in the external glycol circuit, controls the operation of the cooling towers, controls the operation of the internal circuit pumps and regulates the amount of water passing through the precision air conditioners. In summer mode, the automation system additionally controls the operation of chillers (controls the performance of chillers, performs protective functions, automatically detects the transition of the system from winter to summer mode).

Additionally, the automation system monitors and maintains pressure in the internal water circuit.

Circulation pumps can operate both in manual and automatic modes, depending on the position of the Manual-Disabled-Automatic mode switch on the front door of the control panel and automation.

In manual mode, each pump is controlled by its own "Start", "Stop" buttons.

After the “Turn on cooling” command is given, the “main” pumps are turned on.

After the “Turn on cooling” command is removed, the chillers are first turned off, and then, after a while, the circulation pumps are turned off.

The pumps are controlled by a built-in frequency converter. When the pump is turned on, the frequency converter must gradually increase the frequency to the required value. When the pump is switched off, the frequency converter must gradually reduce the frequency to 0

The presence of any alarm leads to the removal of the command to turn on the corresponding pump. At the same time, the “emergency” lamp lights up on the door of the automation and control panel.

The accident is reset after the cause of the accident has been eliminated by pressing the "accident reset" button on the door of the automation and control panel, or by the operator using the ASDU system.

III.1.5 Automation of pumping drainage sewers

The automation system for pumping drainage sewerage provides the following functions:

The water level in the pit;

Automatic switching on of the working pump, and in case of failure of the backup pump;

Automatic selection of working and standby pumps to ensure uniform generation of motor resources;

Manual control of pumps using switches and buttons on control panels;

Light signaling, on the facade of the automation panel:

o pumps - “on” / “emergency”;

o the presence of voltage in the network.

III.1.6 Lighting control automation

The lighting control system consists of floor lighting control automation boards, in which controllers and I / O modules are installed, push-button lighting control panels, LCD lighting and climate control panels and multi-sensors for illumination.

Automation of lighting control systems provides the following functions:

Manual control of lighting groups from wall-mounted keypads, either individually or by several groups at the same time;

Automatic control by multisensors of presence and illumination, as well as by schedule, in order to save energy and the resource of lighting devices.

III.1.7 Air conditioning automation

The air conditioning automation system consists of control controllers installed in air conditioners and temperature and humidity sensors. The controllers are equipped with an interface for connection to the ASDU system.

Automation of air conditioning systems provides for:

Manual control of the temperature setting and fan coil fan speed from the wall panels;

Automatic equipment control;

Remote control from the operator's workstation;

Maintenance and measurement of indoor climate parameters.

III.1.8 Clock system

The clock system (CH) is designed to create a unified time system and time synchronization for all systems. In addition, the MF allows you to visually display the time for employees using secondary clocks connected to a common MF.

Clock microprocessor station STS is designed to control secondary clocks - analogue and digital, various actuators, as well as to synchronize computers and computer networks. The modular structure of the clock station allows you to configure it in accordance with the tasks to be solved, as well as add the necessary modules to an already installed station and, if necessary, expand the functionality of the unified time system

Dispatch system is designed to remotely display the collection and storage of data on the operation of the technological equipment of a building or a production process, it transmits information about the parameters of ongoing processes, operating modes of engineering systems, and emergency situations. The interface of the dispatching system allows the operator to remotely set the operating modes of the system as a whole or individual equipment.

The requirement for the presence of dispatching systems in modern buildings is determined by SP 31-110-2003 "Design and installation of electrical installations of residential and public buildings". VSN 60-89 “Communication, signaling and dispatching devices for engineering equipment of residential and public buildings. Design standards” - regulates the design of dispatching systems.

Thus, the main purpose of the dispatching system is to centralize the control and management of the building.

There is sometimes confusion when a building management system is defined as a building management system BMS. This is due to the fact that controllers and SCADA software of BMS systems will be used in dispatching. However, the dispatching system is an interface part of the smart building system, it only outputs information to the control panel and allows the operator to manually control part of the processes, albeit remotely. Algorithms for optimal and economical interaction between building subsystems must be developed by the automation project and programmed in the control controllers, only then the operator is freed from making most of the routine decisions.

The dispatching system is not a complete automation system! It performs functions related to display - "supervisory control" and manual remote control - "supervisory control" of engineering systems.

Typically, the functions of the dispatching system include:

• Data collection from devices and visual display of processes occurring with the engineering equipment of the building (for modern systems, using SCADA);
• Timely detection of emergency situations, prevention of accidents;
• Formation and sending of alarm messages to responsible persons;
• Remote control of engineering systems devices;
• Collection and storage of instrument readings in automatic or manual mode;
• Presentation of data in graphical and tabular form;
• Maintaining reports on energy consumption, generating reports automatically and at the request of the operator;
• If necessary, transfer data to a higher priority remote control.

Information flow from the following systems is displayed on the dispatcher console:

• supply and exhaust ventilation;
• Air conditioning and refrigeration;
• heating;
• Heat supply (ITP or boiler equipment);
• Water supply, water treatment, sewerage;
• Lift and escalator equipment;
• Power supply and electric lighting;
• Fire alarm and building security systems;
• Sound control systems;
• Fire-fighting automation (smoke ventilation and fire extinguishing);
• Other systems related to production or process control.

Outside air temperature, chilled water to/from the ventilation system, chilled ethylene glycol, heated heating water can be displayed; pressure values ​​of chilled water or ethylene glycol of ventilation and air conditioning systems; control valve positions; power on the motors of circulation pumps or fans; ; filter clogging data; alarm about the threat of freezing heaters information about the state of elevators, supported by video data; state of circuit breakers in electrical panels, etc.

The control of equipment in dispatching is limited by the ability to enable certain operating modes, for example, the system start mode in winter or summer, maximum performance mode, emergency shutdown of the unit, manual switching from the main to the standby pump, etc. In theory, the dispatcher has the ability to control each of the devices with a drive, but in practice, one person physiologically will not be able to manually control a large engineering system.

The management of such a system is carried out 24/7 by qualified personnel who have completed specialized training courses. In addition, for each system in the process of design, commissioning and operation, technologists develop action protocols for possible emergency situations.

Possibilities of modern dispatching systems

Modern dispatch systems are increasingly implemented on controllers and software of BMS systems. This causes a large number of software options for customizing their functions. In general, dispatch systems should provide:

• An up-to-date and complete picture of the state of all engineering systems at any time;
• Convenient and clear graphical interface;
• Quick response to emergencies;
• Possibility of issuing emergency messages on the monitor screen, printer, remote computer, mobile phone;
• Registration of all system events, which in many cases makes it possible to establish the cause of the emergency, its culprit, and also prevent its occurrence in the future;
• Connecting to the system remotely via an Internet browser;
• Quick and adequate response to changing environmental conditions;
• Automatic counting of engine hours, equipment time to failure and warning about the need for maintenance and preventive maintenance;
• Ample opportunities for managing systems, which allows to reduce the staff of maintenance personnel;
• Possibility of collecting statistical information, forming samples, graphs comparing cost forecasting.

The difference between a dispatching system and a building automatic control and dispatching system (SAUiD)

The main differences between the functions of the engineering equipment dispatching system and the building automation system are visible in the diagrams below. Typical scheduling scheme for engineering systems of an object

Typical scheme of automation and dispatching of engineering systems of an object (synonyms: BMS, intelligent building)

Thus, the dispatching subsystem is only part of the BMS building management system.

Equipment and software for dispatching systems

The task of dispatching is to display information and provide control, therefore, the main elements of the dispatching system are operator software and interface converters, often installed in automation panels of engineering equipment.

As a rule, modern automation controllers have the ability to work with SCADA software of the dispatching system, they are also interface converters. The software provides the implementation of such functions as:

• Displaying information in the form of mnemonic diagrams with the issuance of real-time measurement values, controller settings, various icons and other graphic objects;
• Formation and issuance of emergency messages;
• Maintaining archives (trends) for all hardware signals and calculated technological variables;
• The possibility of correcting the operation of the system, without stopping it;
• Possibility to search and filter records of archives by a number of selection criteria; the ability to generate reports based on user-defined templates; viewing archived information in the form of graphs and tables;
• Ability to create schedules, multi-level access and other functions of computer control systems.

Data transfer from the local automation system to the SCADA dispatch system can be carried out directly or through the interface of the OPC (Open Platform Communication) server. Wherein OPC server is a translator between the language that the installed equipment understands and the language of the dispatcher's software interface.

The main goal of the OPC standard was to provide the possibility of joint operation of automation tools operating on different hardware platforms, in different industrial networks and manufactured by different companies.

After the OPC standard was implemented, almost all SCADA packages were redesigned as OPC clients, and every hardware manufacturer began to supply their controllers, I / O modules, smart sensors and actuators with a standard OPC server. Thanks to the advent of interface standardization, it became possible to connect any physical device to any SCADA, as long as they both complied with the OPC standard. Developers got the opportunity to design only one driver for all SCADA packages, and users got the opportunity to choose hardware and software without the previous restrictions on their compatibility.

IP equipment

90% of modern dispatching systems have the ability to exchange information over IP networks. The conversion of data into the appropriate protocols takes place either directly in the controllers, or on top-level servers (Schneider Electric Automation Server), or through gateways, for example, Xenta-911.

With cheaper IP equipment, the functions of data transmission to the network are gradually being extended to field devices (valves, frequency converters, etc.), but this solution is still more expensive in any case, and also requires the development of a stable and secure SCS at the facility, this is true is an expensive undertaking.

IP equipment for automation and dispatching engineering systems is selected depending on the requirements for its functions. As a rule, it is enough to have a software interface between the dispatching system and the enterprise IP network, and it becomes possible to connect additional information to the SCADA system. In particular, for visual monitoring of important nodes or premises from the control room, IP surveillance cameras of the industrial television or security system are connected to the system.

Development and design of dispatching systems

The project of the dispatching system is carried out by section of the set of drawings of the building automation and dispatching system. The signals output to the dispatcher's console are determined by the developers of the building systems technology.

Design standard: VSN 60-89 “Communication, signaling and dispatching devices for engineering equipment of residential and public buildings. Design standards»

A dispatch system design will typically contain the following sheets:

As part of the dispatching project, the dispatcher's automated workplace is also being developed. Depending on the scale of the system, it can be equipped with:

Shield with applied mnemonic diagram(at present, such systems are less and less common in production);

PC with installed SCADA software;

PC with web interface access to the controller-server of the system (example: automation server Schneider Electric);

PC with installed SCADA system with access to multiple monitors and monitor wall.

At each facility, whether it is a production facility, an office center or a large industrial enterprise, there are many engineering systems that are continuously operating. These include ventilation systems, water supply, power supply, etc. Many nodes of such communications are located in places that are difficult to access for constant diagnostics; it is difficult for a person to maintain them and constantly monitor their condition. To solve such problems, the design of dispatching and its subsequent installation are carried out.

Dispatching systems are a combination of both hardware and software tools that are used to continuously monitor the state of equipment, subsystems, as well as centralized management of operations and processes and timely detection of emergency situations.

• Sensors, measuring devices, devices for collecting information;
• Equipment used to transmit data from measuring devices and computer centers;
• Computing devices, server;
• Operator's workplace, user interface;
• Software, both general and specialized, databases.

The introduction of dispatching systems is especially effective at large facilities and can significantly reduce the human factor, as well as increase the reliability of engineering communications and prevent emergencies.

Dispatch systems provide the following features:

• Notification of the status of subsystems and equipment operation;
• Notification in case of emergency and emergency situations;
• Remote centralized management of operations and processes of subsystems;
• Control of climatic indicators, as well as water supply parameters;
• Effective fire protection;
• Ensuring security, access control, video surveillance;
• Archiving, storage and processing of data received from all systems.
