Abstract

A system for comprehensive protection of objects, comprising security and fire alarm units connected via a communication line, characterized in that the system is decentralized, and each of the security and fire alarm units is designed to operate autonomously.

Description

The system is designed to comprehensively protect objects of any complexity from unauthorized entry and fire, as well as to manage the engineering systems of these objects by collecting, processing, transmitting, displaying and recording notifications about the status of security, alarm and fire alarm loops, as well as recording and displaying video information.

Integrated systems are known, for example, the Orion security system (NVP BOLID, Korolev).

The disadvantages of the closest analogue are:

1. A small number of pieces of equipment (addresses) in the system (127).

2. Lack of flexibility in the formation of algorithms for the operation of the components of the system (rigid logic).

3. The system is built in such a way that its “head” is the central console, which interrogates the state of all components of the system, makes a decision on how to respond to a change in the situation (at the object), and transfers the decision (command) to the corresponding component of the system for execution. In this case, in the event of an emergency disconnection of the central console from the interface, the system will stop functioning.

4. For the same reason, in the event of an emergency disconnection of a part of the system from the system interface, disconnected units of the system “die off” and do not take part in the operation.

5. The system polling algorithm is designed in such a way that the appearance of a faulty unit in the system leads to a sharp increase in the response time of the system.

6. The system allows you to connect to it only one additional central console (except the main one), which prevents the management of subsystems by different users.

7. When the AWP is connected to the central console, the latter only starts to perform the buffer function between the AWP and the system and cannot provide any control on the system’s performance.

8. Video surveillance and alarm functions are combined only at the computer level (AWP).

As the closest analogue adopted the system of integrated protection of objects, known from patent RU 66579 U1, publ. 2007. A well-known centralized system contains a fire alarm device, with which via communication lines

the devices installed at the facility are connected: security and fire alarms, access systems, warning and evacuation control systems, fire extinguishing, smoke removal, as well as video reception / transmission devices.

The known system has the same disadvantages as the above Orion system, because it is also centralized, i.e. contains the main control element - the central console in the form of a fire alarm device.

The technical task of the proposed utility model is to expand the functionality of the system.

The problem is solved in that the system for the integrated protection of objects, containing the security and fire alarm units connected via a communication line, is decentralized, and each of the security and fire alarm units is designed to operate autonomously.

The implementation of a decentralized system means that all elements (blocks) of the system are equal in terms of requests and the issuance of information messages about events occurring in the system. In well-known technical solutions, i.e. centralized systems, the presence of the Main element is assumed (other terms:

Server, Master, Master, etc.), which makes requests to other elements of the system (other terms: Client, slave. Slave, etc.) and controls their actions. If the main element fails, then the whole system will lose its performance. In a decentralized system, any element can transmit or receive information at any time, without waiting for a request from the Main element, which is absent in the system. Any element of this system does not guarantee anyone their presence on an ongoing basis. It can appear and disappear at any given time. If some element fails, the remaining elements will continue to function.

In the event of a cable break in the system according to the closest analogue, the Main element will lose the physical ability to transmit control messages to other elements and the system will cease to fulfill its functions. In a decentralized system, a cable break will lead to loss of communication between the elements at the break, but in the remaining segments, the elements will continue to exchange messages with each other. Embodiments of the utility model shown in the diagrams (Fig.1, 2)

A system (see Fig. 1) for integrated protection of objects comprising connected via a communication line, for example, CAN network, security and fire alarm units, each of which is designed to operate autonomously, i.e. perform their functions independently of other blocks. These blocks perform various functions and can

be at a distance of 1500 m from each other. All units connected to the network can give out important information (for example, about a fire, alarm situation, about a malfunction) without waiting for a request from the central console (CPU), as is done in devices from other manufacturers. Failure, or loss of any block, incl. and the central console, will not cause the cessation of the functioning of the system as a whole. The remaining elements will perform their functions. A break in the CAN network cable will not cause the entire system to stop working. The subsystems formed as a result of a complete break in the connecting cable will continue to function.

CPU1 - to control the fire alarm system of building No. 1 (factory);

CPU2 - to control the fire alarm system of building No. 2;

CP3 - to control the fire automatics system of the plant;

CPU4 - for controlling a video surveillance system, etc.

An example of the proposed system is illustrated using the circuit shown in figure 2

The system combines 8 elements (blocks) that perform various functions. In case of failure of the “relay unit 2”, its function can be performed by the “relay unit 1”, and the remaining elements will continue to exchange messages. In the event of a cable break, “loop unit 3” and “relay unit 1” will lose communication with the rest of the system units, however, they will continue to exchange messages with each other. Continuing the exchange of messages between themselves and the remaining other blocks.

The main differences of the proposed system:

1. Increased the number of pieces of equipment (addresses) in the system (510).

2. Each element of the system (the algorithm of its operation and its parameters) using the special program "Configurator" can be user configured according to the original algorithm, as applied to the specific object on which this equipment will be installed.

3. The system is constructed in such a way that the algorithm of operation of the entire system as a whole, as well as of each element of the system set using the Configurator program, allows the system to work not only as a whole, but also independently of each element separately. That is, when the system is destroyed, the remaining workable elements will continue to work autonomously (including jointly). Moreover, the presence of a central console in the system is not a prerequisite. At the same time, the number of central consoles in the system can be any number (it is necessary to observe only the total number of elements in the system, which should not be more than 510 pcs.).

4. The system allows you to connect to it any number of central consoles (up to 510 pcs.), Which allows you to organize subsystem management for various users, for example:

CPU1 - to control the fire alarm system of building No. 1 (factory);

CPU2 - to control the fire alarm system of building No. 2;

CP3 - to control the fire automatics system of the plant;

CPU4 - for controlling a video surveillance system, etc.

5. The system polling algorithm is designed in such a way that a faulty unit of the system is excluded from the number of elements being polled, which does not lead to an increase in the reaction time of the system.

6. When connecting the AWP to the central console, the system can be controlled both using the AWP and the central console. 8. The video surveillance and alarm functions are combined at the central console level, in addition, in addition, these functions can be simultaneously implemented on a computer.
