Automation and dispatching of engineering equipment for life support of buildings. Dispatching engineering systems

I heard the appeal of dear and respected Volzhanin yesterday. But I have preparation # 4 of the Algorithm for printing. Here, as always, everything is on the ears. On September 10, everything should be in the printing house, and here who is where, summer.
Now in order.
My colleague, dear Volzhanin, is right as always. If it comes about dispatching is one thing. If we are talking about fire monitoring, this is completely different. Do not confuse one with the other and be indignant at his behavior. Here he is like a classic of the genre. He will not take someone else's, but he will not give up his own either.
Now, within the framework of fire monitoring, it is necessary to distinguish between objects of categories F1.1, F1.2. Ф4.1 and Ф4.2. from all others. This is a dogma.
For these objects according to Federal Law No. 123 there is one system fire monitoring with duplication (I emphasize - with duplication, since there must be a round-the-clock security post at these facilities) of signals through Strelets-Monitoring at NCC-01, i.e. in the DDS of the Ministry of Emergency Situations.
According to SP5.13130, objects that do not have round-the-clock security posts go there, i.e. in the DDS of the Ministry of Emergency Situations.
Allowed by 13.14.5.
"Control and control devices and control devices, as a rule, should be installed in a room with a round-the-clock presence of the personnel on duty. technical means to a room with personnel on duty around the clock, and ensuring control of notification transmission channels. In this case, the room where the devices are installed must be equipped with security and fire alarms and protected from unauthorized access. "

But this immediately contradicts 14.4.
"In a room with a round-the-clock presence of the personnel on duty, notifications of malfunction of monitoring and control devices installed outside this room, as well as communication lines, control and management of technical means for alerting people in case of fire and evacuation control, should be displayed, smoke protection, automatic fire extinguishing and other installations and devices fire protection.
The project documentation shall identify the recipient of the fire notification to ensure that the tasks in accordance with section 17 are carried out.
At facilities of functional hazard class F 1.1 and F 4.1, fire notifications must be transmitted to the fire protection units via a duly allocated radio channel or other communication lines in automatic mode without the participation of facility personnel and any organizations broadcasting these signals. It is recommended to use technical means with resistance to electromagnetic interference of at least the 3rd degree of severity in accordance with GOST R 53325-2009.
In the absence of personnel on duty around the clock at the facility, fire notifications should be transmitted to the fire brigade via a duly allocated radio channel or other communication lines in automatic mode.
At other sites, if available technical capability it is recommended to duplicate signals of automatic fire alarm about a fire in the fire brigade through the radio channel allocated in the established order or other communication lines in automatic mode.
At the same time, measures should be taken to increase the reliability of the fire notification, for example, the transmission of "Attention", "Fire" notifications, etc. "

Now according to clause 13.14.5.
What kind of technical means can be used in this case. After all, this requires control, and constant, of this very channel of transmission of notifications. And what kind of technical means.
We pass to Art. 46 ФЗ №123. There we find SPIP for this - fire notification transmission systems.
Where are the requirements for them. Section 9 of GOST 53325-2012.
Do the SPIs used by the PSC correspond to it? Of course not. Since there are used SPIs of a completely different class and with different requirements.
Now a question of another plan.
Three plots came from the object to the remote control of this CHOO. We went to the first two, but did not call the third. People died, a lot of material damage. Who is to blame for the late delivery of the notice.
In this regard, there is a law on private detective and security activities. It indicates that PSCs can perform the following functions: installation burglar alarm, the organization of access control at enterprises and the protection of facilities with the help of technical means. There is no talk of any fire-fighting functions there and cannot be. In this case, according to the law, no one has any claims to the private security company in the event of a fire, even if a fire alarm is connected to them. Who made the unlawful decision to empower the private security company fire brigade object. Facility management. Well, we will put him in prison for 15 years.
But what you do in this situation is up to you. There are laws, there are arbitrage practice, but there is a desire of the customer. The customer’s desire does not always coincide with the capabilities or views of the contractor.
About the project new edition SP5 should not be illusory. For many reasons, it was returned for revision. And the mentioned version in terms of fire monitoring is one of them.
Imagine that they were suddenly allowed to transmit a fire signal to any organization, if only there was a 24-hour duty officer and any technical means.
From city A from the children's rehabilitation center, a fire signal automatically goes to city B via the GSM channel. And not just anywhere, but in Uncle Petit's garage. And from there, fully drunk, this uncle Petya has to call long distance to city A in order to send a signal about the fire. But Uncle Petit had no money on his phone to make long distance calls. What do you think about it. But the rule-makers from VNIIPO do not see any problems here. Therefore, they were pushed in the ass.
And in terms of choosing a communication channel, there are also a lot of problems.
In general, I give you links to my materials on the organization of fire monitoring:

Read it, figure it out.
But then you can rummage around here on this forum on the part of the legal force of the relationship with the private security company. I wrote a lot here at one time with excerpts from our legislation. Not so simple as it seemed and wanted, but very interesting and informative. This is exactly what our esteemed Volzhanin mentioned here.
In short, this is your first breath. When you figure this out, you can continue to delve into this problem.

Dispatching engineering systems buildings, groups of buildings, enterprises - the bottom of the most pressing problems in the implementation of automated control systems for technological processes - process control systems. Modern engineering systems are complex, complex systems, for the normal functioning of which automated dispatching systems are required. Engineering equipment, which is part of the life support complex of buildings, has, as a rule, a huge set of technological parameters and signals that require continuous monitoring. Only modern systems dispatching.

Dispatching engineering systems allows you to expand the traditional automation of engineering systems and bring it to a level where monitoring and control of all systems is carried out from one dispatcher's workplace. Dispatching of engineering systems allows maintaining their operability and increasing the efficiency of energy resources use. Thanks to the operational control of the state of engineering systems and timely response to changes in the operation of systems and equipment, it is possible to make effective management decisions and prevent possible failures.

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

When using dispatching systems for engineering systems, the rationality of using all types of resources increases and thereby increases the profit from the operation of facilities. The automated dispatching system for engineering systems makes it possible to take into account energy resources, normalize their consumption, and adjust the operation of equipment taking into account external conditions. Thus, the client can save a significant share financial resources and direct them to business development.

STC Energo-Resource effectively develops and implements automated dispatch control (ASDK) and control systems (ASDU) of engineering systems of various objects:

industrial facilities and enterprises;
business centers;
shopping and entertainment centers, hypermarkets;
detached buildings or complexes of residential buildings;
sports facilities;
medical institutions;
warehouse complexes;
individual plots within an industrial, economic, public, office or residential facility.

Implementation of the ASDK dispatch control system, and, if required, the ASDU dispatch control and management system allows:

Display information graphically and visually;
Maintain accounting and analysis of energy consumption;
Carry out round-the-clock operational management, depending on situations at the facility;
Quickly, reliably diagnose the condition of the object;
Reduce the level of exposure to the human factor;
Significantly reduce the number of maintenance personnel;
Reduce operating costs;
To plan service maintenance equipment;
Operatively track failures, preventing the development of emergency situations in a preventive mode;
Issue contextual hints to the dispatcher in emergency situations;
Keep a log of events in automatic mode, documentary determination of the causes of accidents, losses and their perpetrators;
Obtaining and analyzing data for the development of measures aimed at improving energy efficiency.

Dispatching covers engineering systems:

Indoor and outdoor lighting;
Boiler plants and individual heat points forming a heat supply system;
The elements exhaust ventilation(BB) and supply ventilation(PV), central air conditioners and air conditioners-closers (fan coil units, thermal curtains, air flow regulators);
Refrigeration centers and refrigeration supply stations;
Security and fire alarm systems (smoke removal equipment, fire valves, water and gas fire extinguishing etc.);
Separate wells and water intake units, pressure boosting units;
Cold water supply (HVS);
Hot water supply (DHW);
Leakage control (flooding and drainage);
Diesel power plants, transformer substations, powerful UPS, power distribution devices;
Energy resource metering units;
Elevator facilities and escalators;
Access control and management systems, video surveillance.

The dispatching system of engineering systems is a multilevel remote monitoring and control system. It includes:

Lower level (field level): sensors, actuators and cable system... The lower level can include from units to thousands of signal sources interrogated by sensors, various devices connected by different types interfaces transmitting information to the equipment of the middle level.

Average level: controllers that receive and process analog, discrete signals and generate control commands. Middle-level equipment is programmable controllers, modules of discrete, analog inputs, relay inputs and outputs. The controllers transform the data received from the monitored equipment, preliminary calculations equipment states, data packets formation, and also generate signals for controlled devices. An object can contain hundreds of such controllers, depending on the structure and size of the object.

Upper level: control computer with application software (operator workstation). The top-level hardware is a computer with special software. It requests and receives data from controllers.

The software, with which the operator works, displays the equipment involved in the system in a convenient form for the operator (building layouts indicating the location of equipment, structural chains of equipment for various subsystems). It is possible to work with the logs of alarms, events, actions of operators, filtering events in the logs by date, time, type of event, type of equipment. The operator's workstation can set the parameters of the equipment operation, with the appearance of alarms when the parameters go beyond the specified limits, display the statistics of changes in the system parameters in the form of graphs and tables. The differentiation of user rights is also carried out according to the possibilities of management, dispatching of engineering systems.

Dispatch post (operator workstation) equipped with an uninterruptible power supply, sound alarm and includes 3 monitors (left, center and right). From the point of view of placing information on them, each monitor is independent and self-sufficient. Any frame with information can be displayed on each monitor. The distribution of frames with information on monitors is made by the dispatcher himself, based on his own preferences and ease of perception.

There are the following types of frames:

Start frame;
Main mnemonic diagram of buildings;
The main mnemonic diagram of the structure;
Mnemonic diagram of the contour of the engineering system;
Mnemonic diagram of the equipment floor plan.

For quick troubleshooting, a floor-by-floor mnemonic diagram of the equipment placement is provided on the screen, on which it is possible to accurately determine the location of the emergency equipment.

After putting the dispatching system into operation, NTC Energo-Resource company provides service maintenance of the system. The company's specialists, in agreement with the customer, using remote access, can see the real picture of what is happening in any dispatching circuit of the customer's object in the “on-line” mode and make the necessary changes to the software.

The need to use dispatching systems for engineering systems is obvious. They enable reliable interaction between all subsystems of the object's life support, operational control and management. The more complex the engineering complex of the facility, the more important is the role of dispatching systems.

Energy efficiency
Intellectual energy saving system building automation reduces emissions harmful substances and allows you to reduce operating costs.

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