Description

The invention relates to fire and security and other types of signaling and can be used in devices for centralized protection and monitoring of dispersed objects through radio channels.

The known alarm system "Cyclone" (TU 25-08. 430-80, TU 25-08. 431-80, TU 25-08. 432-80 Security Technique No. 1/94) containing groups of subscriber sets connected respectively to a group of concentrators that are connected in parallel with a dedicated communication line with a central monitoring station (CMS), and all concentrators in the group are additionally connected to each other in parallel with the control bus.

The disadvantage is the low reliability of this burglar alarm system, which is associated with a large number of false alarms due to a decrease in the level of the continuous frequency signal transmitted from the guarded object when the parameters of the telephone communication line deteriorate, and the inability to protect objects with which there are no telephone communication lines.

A well-known fire alarm system (RF Patent No. 2110094, containing a group of central monitoring stations, each of which contains a primary and backup control file device (UFD), a group of subscriber sets connected to the inputs of the respective concentrators, a group of concentrators of the corresponding set of equipment of an automated telephone exchange ( ATS), in which each hub contains a microcomputer,

the first input of which is connected to the first output of the switched power supply, and the first group of inputs / outputs of which is connected to the first group of inputs / outputs of the first communication unit, the second group of inputs / outputs of which is connected to the corresponding telephone lines of the telephone exchange, and through the controllers of the local network, the group of hubs is connected with the corresponding group of multiplexers, which are connected through communication units to the corresponding UVUs of central monitoring stations.

The disadvantage of this system is the inability to protect objects not connected to the system by wired communication lines.

The closest in technical essence to the proposed solution is a fire and security alarm system (RF Patent No. 2177179, containing a group of central monitoring consoles, each of which contains a primary and backup control file device, a group of subscriber sets connected to the inputs of the respective concentrators, a group of concentrators of the corresponding set automatic telephone exchange equipment, in which each concentrator contains a microcomputer, the first input of which is connected to the first output of the switched power supply unit and the first group of inputs / outputs of which is connected to the first group of inputs / outputs of the first communication unit, the second group of inputs / outputs of which is connected to the corresponding telephone lines of the PBX, and the concentrators of the set of PBX equipment contain a restart unit and a second communication unit, the first group of inputs / the outputs of which are connected to the corresponding inputs / outputs of the file control devices of the central monitoring panels, the second group of inputs / outputs of the second communication unit is connected to the second group of inputs / outputs of the microcomputer, the third group of inputs / outputs of which is connected to the group of inputs / outputs of the restart unit, the inputs of which are connected to the second and third outputs of the switched power supply, and the output of the restart unit with the second input of the microcomputer.

The known system of fire alarm works as follows.

In the initial state, after the power supply of any monitoring station is turned on, the control panel displays the initial menu for the standby mode, and the monitoring stations switch to the cyclic poll mode of the current state of the respective concentrators (CC) via the corresponding communication lines between the monitoring station and the control center.

After turning on the power, the control center performs the necessary programming and diagnostics of its internal nodes, and the restart unit blocks the issuance of the restart signal to the microcomputer of the control center for a period of time during which the microcomputer performs the necessary preparatory and diagnostic operations and proceeds with the main program.

After successfully conducting Micro-computer internal diagnostics of the CC nodes, it checks the presence or absence of voltages on the main and backup source of the switched power supply. After that, the microcomputer transmits these states to the corresponding monitoring station, and if there is at least one of them, it starts to execute the main program, which it reads into its RAM from the ROM. If the program is executed correctly, the restart unit does not generate a restart signal in the microcomputer and other electrical circuits of the corresponding CC. All the results obtained by micro computers as a result of diagnosis are transmitted to the corresponding monitoring stations. Information exchange between the monitoring station and the control center is carried out through the communication lines connecting them to the microcomputer of the control center through the second communication center of the control center. If the results of the diagnosis of CC carried out by a microcomputer are successful, then the microcomputer includes an appropriate light indication. The CC through the communication line requests the corresponding monitoring station to download the information of this CC necessary for operational work. After the successful transfer of information from the corresponding monitoring station to the control center, the control center checks the integrity of the received information, and if the information is reliable, then it writes it to a non-volatile memory (ENZU) in the appropriate place on the RAM of the microcomputer. Only after that it transmits to the monitoring station a confirmation of receipt of information. If the information turned out to be unreliable, the CC again requests it from the monitoring station. In accordance with the information received by the monitoring station, the CC interrogates and monitors the operation of the corresponding subscriber sets by transmitting the necessary information to them and receiving answers, which they record in RAM and reserve in their ENZU. Then, after analyzing the information received from subscriber sets, the control center transmits it, formed in a certain way, to the corresponding monitoring stations. If during the operation of the corresponding CC there was a deviation in the program execution algorithm or its freezing, the restart block will generate a restart signal in the microcomputer and the electrical circuits of this CC.

After a physical restart, the microcomputer will execute the corresponding section of the program from the ROM for monitoring and initial settings and verify the accuracy of the information in the ENZU. If the test was successful, then the microcomputer overloads this information into its RAM and proceeds to the implementation of the corresponding program for interrogating subscriber sets. If the contents of the ENZU are unreliable, then the microcomputer tests the ENZU, and according to the test results, transmits a message to the monitoring station of the information inaccuracy in the ENZU, and if the ENZU is working properly, it clears it and loads the reliable information transmitted at its request from the corresponding monitoring stations.

The disadvantage of this system is the low reliability due to the lack of a backup communication channel between the concentrator and subscriber sets, the inability to protect objects that are not connected to the system by wired communication lines.

The aim of the invention is to expand the zone of protection and monitoring of objects, increasing the speed and reliability of the alarm system.

This goal is achieved by the fact that in a fire alarm system containing a central monitoring station, a group of subscriber sets and a group of hubs, in which each hub contains a microcomputer, the group of inputs of which is connected to the group of outputs of the power supply, and the first group of inputs / outputs of the microcomputer is connected with the first group of inputs / outputs of the communication unit, the second group of inputs / outputs of which is connected to the inputs / outputs of the central monitoring console, a server block is introduced, and in each subscriber the transceiver unit is inserted into the sample and the hub, the input / output group of the hub transceiver unit being connected to the second group of inputs / outputs of the microcomputer, and its radio wave input / output through the radio channel connected to the radio wave input / output of the GSM channeling equipment, the input / output group of which is connected to a group of inputs / outputs of the server unit, and the radio wave input / output of the transceiver unit of each subscriber set is connected to the radio wave input / output of the GSM channel-forming equipment.

Figure 1 presents a block diagram of an alarm system.

The alarm system of FIG. 1 contains a subscriber set group 1, a subscriber set transceiver block 2, a concentrator group 3, a concentrator transceiver block 4, a concentrator 5 power supply unit, a microcomputer b, a communication unit 7, a server unit 8, a set of GSM 9 equipment, and a central monitoring console (Monitoring station) 10.

The device operates as follows.

In the initial state, after turning on the power of any monitoring station 10, the initial menu for the standby mode is displayed on the console displays, and the monitoring station 10 switches to the cyclic poll mode of the current state of the respective concentrators 3 (CC) 3, via the corresponding communication lines between the monitoring station 1 and CC 4.

After turning on the power supply unit of the hub 5, the hub itself performs the necessary programming and diagnostics of its internal nodes.

After successfully conducting Microcomputer 6 internal diagnostics of the KC 3 nodes and checking for the presence or absence of voltages at the main and backup power supply unit 5, the microcomputer b transfers these states to the monitoring station 10 and proceeds to the main program, which it reads into its RAM from the ROM. If the program is executed correctly, the restart unit does not generate a restart signal in the microcomputer 6 and the remaining electrical circuits of the corresponding CC 3. All the results obtained by the microcomputer 6 are transmitted to the monitoring station 10 during the diagnostic process. Information is exchanged between the monitoring station 10 and the central control center 3 via communication lines connecting them with a microcomputer 6 through the communication unit KTs 4. If the diagnostic results made by the microcomputer 6 are successful, then the microcomputer 6, through the communication line, requests the monitoring station 10 to load information from this KTs 3 necessary for operational work. After the successful transfer of information to CC 3 from the monitoring station, CC 3 interrogates and monitors the operation of the corresponding subscriber sets 1 by requesting information about their status from server 8, through the transceiver blocks of the concentrator 4 of subscriber set 2 and, the GSM radio channel and GSM 9 channel-forming equipment (for example, operating in the USSD channel of the GSM900 / 1800 standard), a group of inputs / outputs of server 8. Server 8, after turning on the power and receiving a poll from the corresponding KC 3, through its own group of inputs / outputs, channel-forming GSM equipment, I’m glad Ocana GSM, and the transceiver unit 3, KC 4 requests the information (address, data coding methods, periodicity of treatment on the server 8, and other necessary for

information) about the subscriber sets 1 serviced by this KC 3. KC 3, having received a download request from server 8, transmits the required information to the server in the next communication session via the communication channel described above. After receiving information from the corresponding CC 3 about subscriber sets 1, server 8 is switched on to standby mode for calls from these subscriber sets 1. Each subscriber set from the group of subscriber sets 1, after connecting power to it, through its transceiver unit 2, via the GSM radio channel, through GSM 9 channel-forming equipment and server 8 I / O group transfers to server 8 its status and receives from it, through server 8 input / output group, GSM 9 channel-forming equipment, GSM radio channel, receiver unit edatchika 4, control commands for the protection and monitoring facilities. The commands necessary for the protection of objects are also transmitted from the monitoring station 10 to the corresponding control centers 3, and from them to server 8 and the corresponding subscriber set via the communication channels described earlier.

The channelization equipment GSM 9 distinguishes its subscribers from calls from subscriber sets 1 (server 8 subscribers) in the stream of calls to it according to the group of access codes stored in the memory of channeling equipment GSM in advance and branches the stream of calls with these codes to the first group of server 8 inputs / outputs Server 8, unpacking the call flow by special codes, recognizes the calls from its subscriber sets 1 and other subscribers in the call flow, and if the subscriber is a stranger, he will instantly receive a denial of service. If the subscriber is recognized as his own, then server 8 analyzes and writes the message sent from him to his memory for further transmission of part of it to the corresponding CC 3 when they access server 8. In addition, during a communication session with subscriber set 1, server 8 transmits its corresponding control information to the subscriber set 1, as well as information for the subscriber set 1 from the corresponding KC 3, obtained during a communication session of this KC 3 with server 8, which server 8 also stores in its memory.

If the server 8 has registered deviations in the time of the call of the corresponding subscriber set 1 to the server 5 or the termination of the call for a predetermined time, then the server 8 will generate a corresponding message for the corresponding CC 3, which will transmit the CC 3 to the next communication session.

If subscriber set 1 registered a failure or silence of server 8 when making a request to it a specified number of times, then subscriber set 1 through its transceiver unit 2, a GSM radio channel, GSM channeling equipment 9, and a transceiver unit 4 of the corresponding CC 3 transmits to it in predetermined time periods short messages (for example: SMS in the GSM900 / 1800 standard) about their status and receives from this KC 3 reverse short messages via the same communication channel. As soon as the main communication channel of the subscriber set 1 with the CC 3 through the server 8 is restored, the work continues as described above through the main communication channel.

KC 3, having received messages from its subscriber sets 1, during the next communication session with server 8, analyzes them and writes them to its memory in a certain order (alarm and emergency messages are the first, then other information about the status).

At the next call of the monitoring station 10 to the corresponding control center 3, it receives ordered information from it, analyzes and processes it in accordance with the algorithm laid down in the monitoring station program, and in the same communication session with control center 3, the monitoring station 10 transfers the corresponding control and other information necessary for operation information for this KC 3, server 8 and the corresponding subscriber sets of its group of subscriber sets 1.

The proposed device:

- expands the protection and monitoring zone of objects with which there are no wired communication lines by using GSM radio channels as communication channels;

- dialogue with subscriber sets takes place in real time, which eliminates delays in the transmission of messages to the monitoring station and vice versa, and increases the speed of the alarm system working on GSM radio channels as a whole, and also significantly increases the number of serviced subscriber units;

- uses a backup channel of short messages, which is included in the work in case of communication failure in the main channel, which increases the reliability of communication in the system.
