Description

The invention relates to systems of fire alarm and monitoring facilities and can be used to transmit information from subscriber kits to central monitoring stations via radio wave communication 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 hubs that are connected in parallel a dedicated line of communication with the central monitoring station (CMS), and all the 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 known fire alarm system (RF Patent No. 2177179, containing a group of subscriber kits, a group of central monitoring consoles, each of which contains a primary and backup control file device, a group of concentrators, the first group of inputs / outputs of each of which is connected to the corresponding subscriber kits, the second the group of inputs / outputs is connected to the corresponding telephone lines of the PBX, and the third group of inputs / outputs is connected to the corresponding inputs / outputs of the main and vnogo control device file corresponding to central monitoring.

The disadvantage of this system is the lack of a backup communication channel with a subscriber set and the inability to protect objects that are 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. 21110094), containing a group of subscriber sets, each of which is made in the form of an object unit and a low-pass filter, connected to the input / output of the corresponding concentrator, which through a local the communication network and through the multiplexer and two dedicated communication lines is connected respectively to the first inputs / outputs of the low-pass filter blocks of the main and backup file control device pool this observation, with the input of the microcomputer of each file control device connected to the keyboard output, the first output of the microcomputer with the input of the display, the second output of the microcomputer with the input of an alphanumeric printing device, the input / output of the microcomputer through the LAN controller connected to the corresponding input of the local network , the group of outputs of the microcomputer through the restart block is connected to the corresponding group of inputs of the block of directions of restart, the first group of inputs / outputs of the microcomputer is connected to the group of inputs / outputs of the memory block from storage ly, a second group of inputs / outputs of the microcomputer is connected with a group of I / O input / output devices, a third group of input / output unit of the microcomputer via the serial I / O controller and transceiver unit connected to a second group of input / output of low pass filter block.

A known set of alarm systems works as follows.

In the initial state, after turning on the power of the monitoring console (PN), the microcomputers of the main and backup file control devices (FCUs) are loaded from their memory blocks with long-term storage of the functioning programs into their random access memory (RAM) and begin to execute them.

Through the corresponding keyboard input device, all the necessary information for the objects on which the object blocks from the group of subscriber sets are installed is entered into the main or backup FUU through the keyboard input device. Information about protected objects consists of: address of the object; codes of keys-tokens of authorized access to the object; the necessary information about the persons responsible for installing and disarming the relevant facility; location and plan of the facility and other information necessary for the operation of the fire alarm system.

All this information is recorded in the memory unit with long-term storage of the main FUU and is automatically copied through the local network to the backup FUU, the main FUU prepares the necessary information messages for transmission to the multiplexer. Initially, the main FUU operates in active mode, and the other in hot standby, this is determined by the feature entered into the corresponding FUU from its keyboard, while the FUU, which is designated active, immediately sends a command to the second FUU through the local network, ordering it to switch to the hot standby mode. In addition, any changes in the information in the memory blocks of the active FUU are automatically copied through the local network to the same memory blocks of the FUU of the hot reserve. After turning on the power on the multiplexer, he diagnoses his internal nodes. After that, on the initiative of the FUU, he enters into communication with the FUU, receives information necessary for work from him. From this moment, the multiplexer begins a cyclic interrogation of the concentrator states through the local exchange network. As the concentrators are turned on, they respond to their address in the local area network of the PBX and enter into information communication with the multiplexer. The multiplexer through the local area network of the PBX performs the loading into the hubs of the relevant information necessary for its normal operation of the hub with the object blocks connected to it through a low-pass filter (OB). The exchange of information between the monitoring console (PN) and the multiplexer is as follows. The main and standby FUUs are connected to the multiplexer through busy two-wire telephone lines and cyclically poll the status of the multiplexer. If in the active FUU PN there is information for the multiplexer, then it is transmitted to him. If the multiplexer is defective or there is no connection with it for a certain time, information about this is entered in the system logs of both FUUs, and the corresponding message is displayed with an audible signal on the display of the active FUU. All information exchange between the multiplexer and the FUU is carried out in packaged formats with the necessary controls and confirmations of reliable reception. Each hub, through busy telephone lines and low-pass filters, cyclically polls the status of the connected OBs. The OB survey is performed sequentially according to the telephone line number in the concentrator and the OB number on the telephone line. All information about the change in the OB parameters, the need for arming or disarming the OB is transmitted to the concentrator and sent through the multiplexer to the PN for making a decision, then it is placed in the state log of the corresponding OB. If communication with the OB has ceased, and this OB has been armed, the corresponding alarm message will be displayed on the display of a free monitors. All OB conditions and actions performed with it by the duty officer are recorded in the journal of this OB. OB is installed directly inside the protected object, and its code lock (KZ) on the entrance door of the object. Security and fire detectors are connected to the loopback groups of property and fire protection locks, respectively. The OB input-output is connected by a two-wire communication line through a low-pass filter. A low-pass filter is needed to prevent serial signals from the carrier frequency from reaching the telephone. Having accepted the OB state, the concentrator checks the code of unauthorized entry or fire at the guarded object, fixes the time of the received message and places it on the urgent message stack for the multiplexer to transmit it to the PN further. The FUU restart block restarts the FUU operation, which freezes due to a hardware or software malfunction.

The disadvantage of this system is the restricted area for monitoring and monitoring objects and the lack of reliable communication with the subscriber set due to the lack of a backup communication channel.

The aim of the invention is to increase the area of protection and monitoring of objects by a fire alarm system and to increase the reliability of the system.

This goal is achieved by the fact that in the fire alarm system containing the file control device of the monitoring console, a group of subscriber sets, each of which contains an object unit, the input of the microcomputer of each file control device being connected to the keyboard output, the output of the microcomputer to the display input, the first group of inputs / outputs of the microcomputer is connected to the group of inputs / outputs of the memory block with long-term storage, the server block is entered, and the radio channel block and a transmitter whose input / output group is connected to the second group of inputs / outputs of the microcomputer, and its input / output via a radio channel is connected to the radio wave input / output of GSM channel-forming equipment, the input / output group of which is connected to the input / output group of the server unit, which is via a radio channel GSM channeling equipment input / output, via a radio channel connected to the radio channel input / output of each subscriber set.

In addition, the subscriber kit of the system further comprises a transceiver unit and an interface unit, the first group of inputs / outputs of which are connected to the inputs / outputs of the object unit, and the second group of inputs / outputs is connected to the group of inputs / outputs of the transceiver unit, whose radio wave input / output is via a radio channel connected to the radio wave input / output of the channel-forming equipment GSM, the group of inputs / outputs of which is connected to the group of inputs / outputs of the server unit, which through the radio channel input / output of the channel image GSM equipment, through a radio channel is connected to the input / output block of the radio channel transceiver file control device.

Figure 1 presents a block diagram of a signaling system, which contains a group of subscriber sets 1, a server unit 2, a file control device 3 of the monitoring console, consisting of a keyboard 4, microcomputer 5, display 6, a memory unit with long-term storage 7, a radio channel transceiver unit 8, channelization equipment GSM 9.

Figure 2 presents a block diagram of a subscriber set, consisting of a transceiver unit 10, a pairing unit 11 and an object unit 12.

The system operates as follows.

In the initial state, after turning on the power of the monitoring console (PN), its display 6 displays the initial menu for the standby and information preparation. Microcomputer 5 file control device (FUU) 3 download from their memory blocks with long-term storage 7 of the program of functioning in their random access memory (RAM) and begin to execute them.

In FUU 3 from the keyboard 4 you enter all the information necessary for the functioning of the system and the duty personnel on the objects on which the subscriber kits (AK) are installed 1. Information on the protected objects consists of: the address of AK 1; codes of keys-tokens of authorized access to AK 1; the necessary information about the persons responsible for the installation and removal of the corresponding AK 1 from protection; the location and plan of the facility, and other information necessary for the operation of the fire alarm system.

All this information is recorded in a memory block with long-term storage 7 FUU 3 and FUU 3 prepares the necessary information messages for transmission to server block 2. Microcomputer 5 FUU 3 transmits these messages when accessing server block 2 and receives a response from the server block 2 about functioning corresponding subscriber sets 1 by requesting information about their status from the server 2, through the block of the radio channel transceiver 8, through its radio channel input / output, via the GSM radio channel, through the radio channel input / output channel GSM 9, through the channeling equipment GSM 9 and the group of inputs / outputs of server 2 (for example, operating in the USSD channel of GSM900 / 1800 standard). Server 2 after turning on the power and receiving a survey from FUU 3 through its group of inputs / outputs, through channelization equipment GSM 9, through a GSM radio channel, through a radio channel input / output through a radio channel transceiver unit, requests the necessary information (addresses, data encoding methods, frequency of accession AK 1 to server 2 and other information necessary for work) about subscriber sets 1. FUU 3, having received a request for download from server 2, it transfers to server 2 to the next communication session using the above communication channel information. After receiving information about subscriber sets 1, server 2 is turned on in standby mode for calls from these subscriber sets 1. Object unit 12 of each subscriber set from the group of subscriber sets 1 after connecting power to it through the interface unit 11, which interfaces the interfaces of the object unit 12 with the transceiver unit 10 , through the transceiver unit 10, through its radio channel input / output, through the GSM radio channel, through the radio channel input / output of the channel-forming equipment GSM 9, through the channel image GSM 9 equipment and the server 2 input / output group transmits its status to server 2 and receives from it through the server 2 input / output group, via GSM 9 channel forming equipment, through the GSM radio channel, through the transceiver unit 10, control commands for security and monitoring facilities. The commands necessary for the protection of objects for AK 1 are also transmitted from FUU 3 to server 2 via the communication channels described earlier.

Channel-forming equipment GSM 9 distinguishes its subscriber sets (server 2 subscribers) from calls of other subscribers (in the stream of calls to it by a group of codes when accessing the channel-forming equipment GSM 9 previously stored in memory) and branches the stream of calls with these codes to the first group of inputs / outputs Server 2. Server 2, 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 2 analyzes and writes the message sent from him to his memory for further transfer of part of it to the FCF 3 when he contacts server 2. In addition, during a communication session with subscriber set 1, server 2 transmits its corresponding control information to the subscriber set 1, as well as information for the subscriber set 1 from the FUU 3 obtained during the communication session of the FUU 3 with server 2, which server 2 also stores in its memory.

If server 2 has registered deviations in the time the corresponding subscriber set 1 calls to server 2 or the call is stopped for a given time, then server 2 will generate a corresponding message for FCF 3, which will transmit FCF 3 to the next communication session.

If subscriber set 1 registered a failure or silence of server 2 when making a request to it a specified number of times, then subscriber set 1 through its transceiver unit 10, through its radio channel input / output, through the radio channel GSM channel forming equipment GSM 9, through the input / output unit the radio channel transceiver 8 FUU 3 in a specified period of time transmits FUU 3 short messages (for example, SMS in the GSM900 / 1800 standard) about its status and receives from the FUU 3 reverse short messages via the same communication channel. As soon as the main communication channel of the subscriber set 1 with the server unit 2 is restored, operation continues as described above through the main communication channel.

FUU 3, having received information from server 2 or directly from AK 1, analyzes and processes it in accordance with the algorithm laid down in the FUU 3 program, and also transfers information back to AK 1 or server 2 via the above communication channels, the corresponding control and other necessary for server 2 and corresponding subscriber sets 1.

All information about the change in the settings of AK 1 of the need to take or disarm AK 1 from protection is placed FUU 3 in the status log of the corresponding AK 1. If communication with AK 1 has ceased, and this AK 1 has been armed, then on the display 6 of the FUU 3 corresponding alarm message. All statuses of AK 1 and the actions performed by the person on duty are recorded in the journal of this AK 1. AK 1 is installed, as a rule, directly inside the guarded object. Security and firemen, and other sensors and devices are connected via loops to object block 11. Having accepted the status of AK 1, server block 2 checks the code of unauthorized entry or fire, or another alarm message from the protected object, captures the time of the received message and is placed on the urgent message stack for its further transfer to FUU 3.

Proposed burglar alarm system:

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

- uses a server that conducts a dialogue with subscriber sets in real time, which eliminates delays in the transmission of messages to FUU and vice versa, and increases the speed of the alarm system working on GSM radio channels in general, and also significantly increases the number of serviced subscriber units;

- uses a second, 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.
