Automation and dispatch systems. Dispatching engineering systems Energy management system

The creation of dispatching systems is one of the key activities of Norvix-Technology.

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

Automated control system (ASDU) is required to control engineering equipmentseparated by geographically, as well as located in hard-to-reach places. As a rule, dispatching is included in the management system of multifunctional objects with complex engineering infrastructure, such as office buildings, shopping and entertainment centers, as well as production complexes and other industrial enterprises.

The following subsystems can be included in the dispatching system:

• power supply, gas supply;
• heat and water supply, energy accounting;
• security and fire alarm, fire extinguishing systems and smoke removal;
• ventilation and air conditioning;
• video surveillance, control and access control;
• lift economy and others.

The essence of the design of dispatching systems is to solve the problem of visualization of information on functioning engineering systems and providing the operator the capabilities of direct equipment from the dispatch point. Data on the status of engineering equipment comes from local automation controllers and are transmitted to the server. Processed technological data with the necessary analytical information goes to the dispatching server and are displayed on the screens of computers at the operators' workplaces in a visual dynamic graph form.

Advantages of the system of monitoring engineering systems of structures

The data obtained and processed by the dispatch system are formed in the messages of different typeswhich are archived in long-term storage facilities. Based on this information available at any time, reports are formed.

The dispatch system gives key benefits when managing an object:

• permanent centralized control of engineering systems;
• operational response in emergency situations;
• decrease in the influence of the human factor;
• optimization of document management, reporting systems.

Norviks Technology Company implements projects of dispatching of varying degrees of complexity.

Along with the familiar systems, the company offers a system of dispatching with three-dimensional visualization based on the decision of the new generation of Genesis64. This is qualitatively new level Dispatch monitoring capabilities, which allows the operator to see a realistic image of an object with all parameters affected by specific nodes. The dispatcher can change the details of the visualized objects in the interactive mode, removing the elements of buildings, installations and viewing them from the inside. Three-dimensional visualization will allow virtual navigation according to those depicted objects, offers the means of animation and speakers of volumetric images and other advantages of 3D technologies.

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

Unlike constructive measures, automation of buildings is a less time-consuming and much cheaper means of improving energy efficiency. The automation system is the brain of the building. He integrates information about all engineering systems. It controls heating and cooling, ventilation and air conditioning, power supply and lighting. Therefore, it is the brain of the building that must be endowed with the functions of controlling the use of energy resources. These functions make it possible to reduce the power consumption of the building by 30%.

Automation and dispatch systems are a single control system for a separate building, a complex of buildings, or a separate area inside an industrial, economic, public or residential facility.

What attractive dispatching systems for business? First of all, the ability to significantly reduce the cost of personnel content. In the context of modern management, the replacement of man robot is the only the right decision Optimization of production costs and costs of operation. In addition, the automation of engineering systems eliminates the intervention of the human factor and the problems arising from it, which, as is known, arise in enterprises with a large share of manual labor with enviable constancy.

back side Progress is the release of a significant number of workers employed before providing engineering systems, which does not always mean a significant reduction in company personnel. Qualified employees can always be directed to other areas expanding by optimizing engineering management systems.

Modernization of the management of engineering systems of the object has other advantages. Automation reacts to changes in conditions much more quickly. Thus, due to the more accurate management of the processes occurring in engineering systems, significant fuel and electricity savings are achieved, and a decrease in equipment wear, accidents, and, consequently, the need for frequent repair and replacement of nodes and mechanisms included in the engineering system is observed.

Tasks and principle of operation of dispatching systems

The principle of operation of the management systems of engineering systems is to provide all blocks of the system controllers. Controllers ensure the collection of information about the operation of blocks, and also provide data to the central post with a given periodicity. Each controller installed on a specific area is programmed individually taking into account all the requirements and features of the operation of this unit. Collected together, data coming from controllers are systematized in the central post and through special software are drawn up into a single whole - a graphically reflected report on the operation of the system in real time.

However, the role of the controllers is not limited to the collection of data on the operation of the system. the main task Dispatch systems consists in managing engineering systems of the object.

The dispatch system controls the cold supply, systems fire alarm, controls and manages air-conditioning, ventilation and heating systems, and adjusts the lighting of the premises. In addition, the dispatching system is responsible for the timely response of the air ventilation in the rooms.

The system collects, systematizes and catalogs information coming from controllers. In case of detection of deviations from the specified parameters, the system gives a signal to the controller, which adjusts the operation of this module to achieve regulatory parameters.

In addition, the system analyzes the total energy costs and adjusts the operation of all modules to achieve significant energy savings.

Operations information about the status of the system as a whole and individual modules is displayed on the display in the control room in a graphically form of tables and schemes for perception. This principle of filing information allows you to estimate the operational environment from one glance, and, if necessary, focusing the system from the control panel.

System Software

Engineering system dispatching equipment is supplied with specialized software. This software is collected and processing information, automates the processes of processing, graphical output to the display, and also controls all the modules of the engineering system of the object.

Processor microcontrollers are programmed directly when designing a system for each specific module. Each controller is associated with parameter sensors to collect information, power cabinets of modules for controlling and the central control panel to adjust the control module within the system in general.

Controllers on each module operate autonomously, but as needed to be adjusted by the system.

Software is installed on the main server in the Central Dispatch Paragraph. Display output graphic scheme Systems. Changes in the system work are displayed on the display and duplicate sound signals.

Regardless of its type - whether this house, office or shopping center, or a sports facility, contains a large amount of engineering equipment. Moreover, the share of engineering equipment in the total cost of the building is continuously growing. Why? Because every year, the ideas about the comfort of a person's stay in the building are also steadily increasing.
Currently, in the building of the required sanitary and hygienic conditions, the provision of its safety and security from external situations is engaged in many subsystems of engineering equipment, each of which is characterized by a rather large set of controlled technological parameters and control signals. In the aggregate, they all form what is called the system of life support buildings.
IN generalSuch a system includes the following directions (subsystems):

• ventilation and air conditioning air (inlets and exhaust systems, Central Air Conditioners and Air Conditioners Closers: Fan Coils and Air Flow Regulators, heat curtains);
• fooling (refrigeration center, cold supply stations);
• heat supply (individual thermal item (ITP) or boiler installations);
• water supply, water treatment, sewage, drainage (pump control stations);
• fireman I. security alarm ;
• fire automation (airfield fans and smoke removal fans, flame retardant valves and smoke valves, fire extinguishing system, water and gas fire extinguishing systems);
• power supply and electrical displacement (transformer substation, diesel generator installation, distribution devices, powerful uninterruptible power sources, electric heating pipelines, funnels and drainage trays);
• elevator and escalator equipment;
• Other subsystems are possible.

Why need dispatching

To organize interaction between individual subsystems of engineering equipment, as well as automated operational control And the control is organized by the dispatching system, into which, in the form of individual components, the subsystems of automation of a particular engineering equipment are included.
The need to create such a dispatch system is justified than more engineering equipment. The total number of parameters of control and management of the modern building (complex of buildings) can reach several thousand. Therefore, it is unacceptable for small objects an approach, in which control and management automation is based on separate local controllers embedded in equipment or mounted separately and non-associated in a single system. And that's why.
For example, with the help of one local controller, you can automate water supply (control of pumps, maintaining the necessary pressure and level, automatic switching of the main and backup pumps, etc.). Similarly, with an individual thermal point. Automated control of fire automation is given a little more complicated. It is not enough to simply close the firecuttering valves and turn on the copper ventilation. It is necessary, for example, block the work of the elevators, produce a number of regulatory actions with ventilation. And this is already interaction with other subsystems.
Automation of the ventilation and air conditioning system (often, one of the largest controlled technological parameters and control signals) can, for example, execute local regulators (which is often done). They will be conscientiously controlling the supply and supply and exhaust systems, fans and valves from signals from temperature sensors, humidity, etc., installed in the rooms and air ducts of this floor. However, in the process of operation of already surrendered systems, the service of the operation of many buildings "includes taste" and require, for example, " automated management Groups of objects on schedule. " For this, all local regulators are necessary to combine the local technological network with the output on the controller's PC (i.e., in advance to provide the dispatch system). And it happens that already purchased and long-stop regulators do not even have an interface for connecting to the network ...
True, quite often, the dispatching system is set by the supplier of automatic ventilation, heating and cold supply. However, this installed system Dispatch "Nothing wants to know" about all other subsystems. Because other subsystems, for example, were projected by different design organizations or already "de-facto" were built on a different software and hardware database. Attempts to create a dispatch system in this case are stumbled into serious problems of hardware and software incompatibility and require installation costs. additional equipment or the development of additional software (ultimately - additional money, and considerable).
As elsewhere, in the field of automation and dispatching of buildings there are their "recordsmen" by complexity of automation. This, very often, office and banking centers - it is clear why. But few people know that creating a dispatch system in a modern medical center or a sports complex is not even easier. Such objects are often located on the territory of several dozen hectares and necessarily have in their composition the construction of the so-called technological accompaniment (laundry and dezecarmers, foodstuffs, etc.), requiring certain more stringent sanitary and hygienic conditions and more complex regulations (algorithms) for their management.
In this way, modern building strongly saturated technical means, Automate, dispatch and maintain that is becoming increasingly harder.

What the DEP offers

The approach submitted by the company allows you to build automation and dispatching systems of almost any configuration and complexity using a single unified set of standard software and hardware components developed taking into account specific Russian conditions. In our country, the blind copying of the "intellectual building" on foreign samples may simply be economically and technically inappropriate. The objective reasons for this are the set, most, in our opinion, characteristic - low cost of energy and insufficient qualifications of personnel serving the system after its commissioning. As a result of the "structural distortions" in our country, many potential customers are not only "Intellectual Building", but even simplest system Dispatching is often not affordable.
Therefore, our approach implements the modern level of "intelligence" for fundamentally important buildings of the building, provides the required comfort and energy saving for the price acceptable to the Russian customer.
Our approach to creating such systems allows builders and investors to optimize construction costs, and owners - reduce operating costs.

Set Dekont

Such a fairly flexible and effective toolkit for the creation of the described systems provides a multifunctional complex Decon (2). On the basis of this designer, a single automated system Building operation management. The system provides control and monitoring of ventilation and air conditioning, power supply, heat supply, water supply, lighting, elevator economy, thermal points, pumping stations, fire-fighting automation, smoke removal, and energy accounting. Per lately The possibilities of our approach have significantly expanded due to the Certification of Dekont for use in systems fire and Security Alarm and management.
Thus, the proposed unified software and hardware base provides a single dispatching point (very often it is just one PEVM on all listed subsystems).

• anti-refinery systems;
• power supply systems, lighting and heating;
• heat supply systems, heating and hot water supply;
• cooling systems;
• water supply systems, water treatment and sewage systems;
• fire and security alarm and management;
• accounting energy resources.

Structure of the proposed system

Asda consists of a dispatching point and automation cabinets (Sha), which contain a freely programmable controller with I / O modules that provide control functions and data collection from nearby engineering equipment. The number and location of automation cabinets in each building may be arbitrary and, mostly, depends only on the layout of buildings and installation locations technological equipment. As a rule, automation cabinets are located near engineering equipment.
Often, automation cabinets are completed not only by topological principle ("I control everything next"), but also by functional when one step processes signals with only one unit or group of the same type of units. A functional approach, naturally, is somewhat more expensive. However, on large objects there is so that the service personnel is divided into independent operation services (for example, on "ventilation officers", "electricians", etc.). According to the established regulation, each service has the right to serve only its subsystems and has no right to open other engineering equipment. In this case, the main criterion for designing Shade should be a functional approach.
To manage vital buildings, the building also practices the backup of information and control channels of I / O modules (in practice 10 - 20% of the stock), as well as the installation on a separate controller for each critical circuit (unit) of the system.
The dispatch point is located, as a rule, one personal computer with installed Specialized Software "Arm-Dispatcher". All automation cabinet controllers are connected to a computer through a local technological network (LTS) based on the RS485 interface. The LTS topology does not have restrictions and is determined only from the conditions of the most economical gasket type cable " twisted para On the screen. " The length of each LTS segment can be up to 1.5 km. The number of segments on the network and the total number of connected controllers in the system is practically unlimited.

Main functions

Asda performs the following common functions:

• setting modes of engineering equipment and adjustable settings;
• automatic control of all mechanisms of controlled engineering equipment (pumps, valves, valves, dampers, etc.) with the display of data on their actual status and position on the dispatching item;
• individual and group television management by aggregates and individual devices of various systems of engineering equipment (air conditioners, air conditioners and exhaust installations, pumps, valves, air dampers, etc.) by teams of the dispatcher and automatic on schedule;
• automatic detection of emergency situations, actions to preserve equipment in these situations and to exit emergencies;
• automatic transmission to the dispatching point of emergency and warning signals, their registration and requirement of the dispatcher for compulsory acknowledgment;
• telecision of the parameters required by the dispatcher for operational control and management of engineering equipment, as well as to prevent various emergency and pre-emergency situations;
• telegradation of various parameters (temperature, pressure, etc.) with temperature and pressure regulators adjustable air dampers in order to ensure normal working conditions for technological equipment, as well as maintaining comfortable conditions in the premises.

Additionally, ASDU provides continuous diagnostics of communication channels, the performance of controllers, I / O modules and the operational indication of the dispatcher of the identified malfunction with automatic logging. In this case, the system can run the programmed stop algorithm of the appropriate equipment and starting the equipment while troubleshooting.

Management modes

Asda provides several engineering equipment management modes:

• Fully automatic control;
• Remote manual control of executive mechanisms with the dispatcher's PC;
• Remote manual and remote automatic control of actuating mechanisms from control panels built into Sha;
• Remote manual control of actuating mechanisms using portable minipulds issued by personnel;
• Remote or local manual control from the manual control buttons located either in Sha or directly near the actuator.

In the case of fully automatic control, programmable controllers installed in Sha, implement the operational management process yourself, without the participation of the dispatcher's PC. From the Arm Manager can only come (automatically) a command to change the settings, etc., based, for example, on a predetermined schedule of group management of equipment in advance. The refusal of the computer or communication line between the PC and SA will not stop the system. It will only be difficult to obtain information and change controls. Even in case of failure of the AWP dispatcher, obtaining information and correction of installations (if necessary) can be implemented using local display panels and controls placed on the face surface of Sha or using portable small minipuldes.

Examples

Water supply system

The water supply subsystem manages the operation of pumps, controls the maintenance of the required pressure or level. In order to uniformly generate pump resources, automatic switching of the main and backup pumps are automatically. If the pump is output, the system automatically connects the backup pump, the dispatcher on the PEVM is an alarm message. At the same time, the dispatcher controls: pressure in pipelines before and after pumps, state of pumps, pump performance, levels in drainage veils. If necessary, consuming consumed water for each consumer and throughout the system.

System of heat supply

The heat supply subsystem regulates and maintains the following parameters in the specified limits: the temperature and pressure of the coolant in direct and reverse pipeline (depending on the outdoor temperature, in accordance with the thermal supply organization), the value of the opening of regulating valves, performance and condition circulating pumps. The equipment resource is recorded, operational alarm is provided on the operation of pumps, the exceedment of the limit values \u200b\u200bof pressure and temperature in controlled points. If necessary, taking into account consumed heat, as well as accounting for consumed water for hot water supply.

Ventilation and air conditioning system

The ventilation and air conditioning is monitored and controlled on signals from the rooms installed in the rooms and in air ducts of temperature sensors, humidity and carbon dioxide in the air. Tracking resource I. emergency modes Equipment work. Additionally, with the controller's PC, automatic mode is also controlled by equipment, taking into account the energy saving algorithms - additional modes of operation at low load hours, as well as the development of specified group on-shutdown algorithms.

Power supply system

Power supply system provides:

• control and indication on the PEVM of the position manager of switching apparatuses and power units;
• detection of emergency and pre-emergency situations and failures of equipment to change the position of commutation and protective apparatus;
• automatic switching to backup or autonomous power supply when disconnected or failure of the main nutrition;
• remote control of switching devices and nodes with a PC dispatcher or sha;
• control and accounting of power consumption.

Interaction subsystems

For example, when the fire alarm signal arrives in an automated mode, a number of fire measures performs a series of fire actions, in particular:

• turns off the ventilation plants and air conditioners of the fire area of \u200b\u200bthe building, from where the fire alarm signal came, closes the corresponding flame retardant valves;
• opens the smoke removal valves, includes sample exhaust ventilation on the evacuation paths and the airfield system in the elevator mines and staircases;
• turns off thermal curtains and closers;
• stops refrigerators and pumps in the cooling system;
• the elevator is served a conversion command to the fire mode, the control buttons are blocked, the cabins are forcibly lowered to the first floor and do the doors;
• gives a signal to the remote fireguard district.

In addition, the Flash disk (8MB) is installed in the controllers, on which the algorithms and the necessary control parameters are recorded after the configuration. Controllers have real-time clock - if necessary, on the Flash disk, controllers lead their own data archives and events (with binding to astronomical time), allowing you to restore the picture of the accident or power failure. For local data visualization, a portable remote control with LCD and buttons can be connected to the controller.
You can install additional interface cards (interfaces) to the controller, with which the communication and connected controller capabilities are significantly expanded. For example, any controller can work on modem communication (selected and switched telephone lines), connect to radio stations with a radio network organization, connect to GSM and GPRS communication, transmit data over voltage lines, etc. With the help of interfaces, backup communication channels are also effectively organized.
A wide range of supported hardware interfaces, standard communication protocols provides painless integration with others. external systems. Supported various unique communication protocols (drivers) guarantee an automatic interface with peripheral intelligent third-party manufacturers (local controllers, electrical and heat meters, frequency regulators, etc.).

Automation Cabinets (Sha)

Each step is a design and component, i.e. The number and types of processed signals are selected based on specific technical characteristics automated equipment. Shape layout under the desired set of signals is made by selecting the appropriate number of I / O modules. Inside the cabinet (cabinets are used with degree of protection against ambient - From IP54 to IP65) There is a vertical mounting panel (multi-level installation) on which I / O modules are installed, controller, terminal connectors, relay elements and fastening elements, perforated boxes for supplying cables to modules.
On the door of the cabinet with outside Placed controls / indications (LED indicators, control buttons, local control and control panel).
In the decont complex, special design, circuitry and software solutions are applied, providing effective work for high level electromagnetic interference and unstable feeding voltage. Therefore, it is allowed to place an I / O modules and controllers in close proximity to power electrical equipment: automatic switches, contactors, starters, as well as connecting peripheral equipment by means of separate remote I / O modules (terminal removal). This allows you to create distributed systems and combined automation and control cabinets (ShaU).

Software

The Software AR-Manager provides a modern intuitive user interface, and also includes convenient tools. In particular, the user interface provides the implementation of the following functions:

• displaying information in the form of mnemonic schemes with the issuance of measurement values \u200b\u200bon them in real time, values \u200b\u200bof settings of regulators, various icons and other graphic objects;
• the issuance of emergency messages on non-delicious modes of operation and parameters that go beyond the calculated values \u200b\u200bin the form of alarm of different types on the screen (message in the information window, the color selection of a faulty device) and the transfer of emergency messages to the database to form a failure log, and on the audio device and the printer in real time;
• entering control effects using a keyboard or mouse to change the settings, shifted by mnemoshem, remote manual start and stop technological installations;
• automated "Management of groups of objects on a schedule";
• Maintaining archives (trends) for all hardware signals and calculated technological variables; The number of archived signals, trend groups and the number of trends in the group is limited only by computer resources;
• the possibility of flexible filtering records of archives for a number of selection criteria;
• the ability to form reports based on user-defined templates;
• view archive information in the form of graphs and tables, the ability to export archived data into data formats of other applications;
• Software supports OPC standard to exchange data with other Windows applications (if necessary).

There are means of delimitation of access to the system (operational and archived technological data, adjusting the configuration and installations, issuing control commands), as well as the possibility of organizing at the top level of several jobs for all interested services.
Debugging and downloading software to controllers can be made as locally (at the place of installation, for example, using Notebook) and on the local technological network - through the PC of the dispatch point.

Dispatching fire alarm in the Crimea.

To ensure fire protection, the dispatching item is the basis. This system includes many elements that interact with each other. Among them are alarm system, sensors, fire extinguishing devices and some others. Properly selected elements, as well as their implementation, allows you to preserve the lives of people, as well as minimize property losses.

Such a dispatching point can take control of dozens of objects throughout Sevastopol, so automatic monitoring is an effective mechanism. Dispatch allows you to ensure continuous control over fire alarm systems, inclusion or shutdown automatic fire extinguishingAnd also allows you to adjust such elements as elevators, escalators, doors and curtains.

When installing the fire protection system in the Crimea, special sensors are used, which allow you to determine the correct operation of the entire system. This concerns connecting lines and blocks. If an error is detected, the corresponding signal will appear on the control panel. This information comes in real time, and it means that the staff will be able to respond to it in the shortest possible time.

The dispatch point allows you to interact:

1. Fire alarm . Mostly the signal is one-sided, comes from fire alarm to the dispatch remote control. The dispatcher clarifies the truthfulness of the signal and takes the appropriate actions;
2. Sprinkler fire extinguishing. The operator can send a signal to trigger the fire extinguishing system. Before this, it is necessary to determine the need for these actions by clarifying information;
3. Evacuation alarm. The signal sends from the control room to notify people with the necessary evacuation.

In general, the monitoring of the dispatching item provides:

1. Displays the state of the sensors in all rooms;
2. Removing and arming the necessary sensors, control in remote mode;
3. Timely notification of people about an alarm event, during which it is necessary to evacuate;
4. The ability to automatically and operational response to freelance situations;
5. Provide high sustainability of the entire system to the inner and external influences of various threats.

As for the modern dispatching point and dispatching of the fire system in the Crimea, it is performed using only modern and efficient equipment. Usually such a system consists of several cabinets with automation. The closet contains a relay that reads the information and transmits it to the headcut.

Note that each individual cabinet is installed for one particular building. Therefore, the dispatching point can have a server, with several such cabinets. Signals come and proceed through these cabinets. It is this tool that allows you to provide systems that work around the clock. They control the fire atmosphere and react to instantaneous signaling.

Want to protect yourself and your property? Then you should contact our company, which is engaged in the establishment of fire systems with complete dispatching in the Crimea. Such a system will allow you to control the availability of smoke, as well as increasing the temperature, automatically include fire extinguishing elements, notify the staff and security service about danger and much more. Remember, security is an important component of the modern world.
