Description

I

: The invention relates to a fire alarm technology and can be used for the protection of objects of national economy.

Systems are known for centralized alerting of a breach of a protected object, including object devices installed at the facilities and connected to the subscription line using the contacts of a signal relay, a switching and broadcasting device installed at the cross of an automatic telephone exchange and containing a distribution and control unit, an amplitude selection unit and linear sets connected to subscriber lines using xc clock cycles of a linear relay and a receiving device, install th in the security room. These systems provide security for objects with individual telephones. They, after taking the object under protection, make control of the Abfient line, connection. connecting

protected object with switching device and switching to open circuit and short circuit. If a violation occurs on the object, the contact of the signal relay connected to the subscription line is opened and, by that, cjMbiM sent an alarm signal to the switch and broadcast device, which then goes to the receiving device l. The known device has the following; lack of. mi:

- before handing over the object under protection and when it is disarmed, preliminary telephone calls are required for the materially responsible person at the security dispatch center;

- the receiving device receives alarms when the material and responsible person leaves the object and enters the object;

-Systems do not allow to carry out; objects that have paired or connected in parallel telephone sets; - The systems do not allow for round-the-clock protection of the facility, while maintaining telephone communications; The closest technical solution to this is a device for signaling the state of monitored objects, containing communication lines, irregular blocks installed at the facilities, each of which consists of a code lock, which is connected to the input of the control unit of the unit, the translator containing the linear block , amplifier, selector, descrambler, the first output of which is connected to the first input of the line unit, a counter, a memory block of the type of notifications, a block for enabling information transfer and a pulse generator, the output of which is connected to the account Chick containing the printing unit, the display unit and the electron-geometric watches. The device provides security and fire notifications, allows the materially responsible person to automatically arm an object using an electro-code lock and disarm the system with acknowledgment of the execution of these functions both at the facility and at the receiving device at security station 2. However, this system has the following disadvantages:. - during the security period of the facility, the subscriber line will be disconnected from the equipment of the automatic telephone exchange and connected to the transfer and broadcasting device, as a result of which the object being armed will be deprived of telephone communication. Therefore, at particularly important sites (where round-the-clock security is organized) it is necessary to have a second abentent line; It is possible to protect objects that have paired or connected in parallel telephone sets - it lacks adequate immunity, since for each type of information an alarm, fire, arming an object, disarming an object corresponds to a certain level of voltage, highly dependent FROM the parameters of subscriber lines and interference in them; - a large number of connecting lines; between the switch and broadcast device and the receiver. The aim of the invention is to eliminate the noted deficiencies, to expand the functional possibilities of the system .1-906 of the system to increase the reliability of control of ED, protected and objects.

0 The information signals through the communication lines 7 are sent to the translator 8, which is connected to the communication line 33. The clock pulse generator 9 is executed on a serial binary counter,

5 covered by the feedback through the scheme of coincidence and filled with pulses from a quartz oscillator, expresses pulses with a period of

0 nor T, which are fed to the input of the distributor, made on the serial binary counter 10 and the matrix decoder 11. These blocks provide alternate switching of 5 soda linear blocks 21 to the amplifier 14. If from the transmission unit 1 via line 7 to linear unit 21 received, for example, a continuous frequency signal arming an object arising from the 5Q detail of connecting the output of this linear block 21 to the input of amplifier 14. From the output of amplifier 14, the detected signal goes to the pulse width selector 15, completed. on a serial binary counter, which, when the frequency in the communication link 7 is filled, is filled with the frequency of the high frequency generator 4, and when there is no frequency in the communication link 7, it is reset to zero cc: that is. When there is a continuous frequency on the link 7, a signal appears at its output corresponding to a logical unit. The signal from the output of the pulse width selector 15 is fed to the input of the comparator unit 16. One of the inputs of the comparator unit 16 receives a signal corresponding to the logical unit from the polled unit 21 if there is a continuous frequency signal on the communication line 7. Comparison unit 16 analyzes the signals from the linear unit 21 and the pulse width selector 15. A signal from the comparator unit 16 starts the analyzer 17, performed on the thrust registers, and closes the clock generator 9 for the time it takes for the analyzer i7 to detect the incoming information from the transmission block 1. From the analyzer 17, the detected information is copied to the memory block 12 of the type of notifications executed on the trigger register. The information availability in block 12 of the memory of the type of notifications is analyzed by the information transfer resolution unit 13, which generates information census pulses from the counter-10 and the block 12 of the memory of the type of notifications to the free register of the buffer memory block 18. After the information is copied into the buffer memory block These 18 blocks of information transfer resolution on command from the control unit 19 starts the clock pulse generator 9, the counter Yun deshi4) Attorney 11 connects to the amplifier 14 the next line block 21, the control unit 19, performed on the generator t pulses and the pulse distributor, alternately polls the trigger registers of the buffer memory block 18 and, when finding the register with recorded information, provides a copy of it to the trigger register of the transceiver 20. After receiving the information, the receiver transmits the command to the control unit 19 about its readiness for transmission the code of the object number and the type of message to the information receiving unit 23. The control unit 1.9 generates a command to start the distributor of the transceiver 20, a sequential dual frequency is generated code, which link 33 is supplied to the information receiving unit 23P sync code incoming at the receiving unit 23, OJEC

8 starts the launch of the glitch; gito; l of the transceiver 27, which sequentially records the code in its own trigger register. After receiving the information, the transceiver 27 generates an acknowledgment signal and the transceiver 8 transceiver 20, In the transceiver 20, a previously recorded information is cleared from the timing register by the receipt signal and the control unit 19 is prepared to process the following information. The control unit 26 polls the trigger registers of the transceiver 27 and the trigger registers of the buffer memory block 28. If there is a free register in the buffer memory block 28, the formation from the transceiver 27 is copied to this register and reset with the transceiver registers 27. After recording the information in the buffer storage unit 28, the control unit 26 sends the command to the operating memory unit 29, which is used to search for the cell corresponding to the number of the object from which the information came. This information is recorded in the RAM 29 and is stored there until the state of the protected object changes. The RAM 29 operates in a dynamic mode, and in order to view the state of the RAM memory 29 upon a command from the operator, you can call specific arrays of the RAM memory 29 on the memory 30, operating in static mode, that . allows you to display information on the light panel 31 of the operator's console. In addition, after recording the received information into the buffer storage unit 28, the printing unit 24 is turned on and prints the object number, the type of information and the time it arrives from the electronic clock 25. At the same time, the display unit 32 displays the object number from which the message was received and kind of information. If an object has received a service information signal, for example, disarming an object or disarming an object, then the print unit 24 will automatically reset the indication in the display unit 32 after printing. When a signal is received from the transmission unit 1, the line unit 21 the signal of information about a violation at a guarded object or a fire signal, the translator 8 and the information face block 23 work in the same way as they were received by the research institutes from the signal transmission unit 1, for example, arming the object. But after printing the information, the light indication of the block 32 is not automatically reset, but is reset by the operator while the trigger register of the buffer memory block 28 is reset. The control unit 22 periodically generates a service code characterizing the operability of the translator 8, which enters the control unit 23, in the memory unit 12 of the notification type. If the service unit does not arrive at a certain time interval at a certain time, the operator’s receiver turns on signal of accident, translator 8 ,. The use of the device will allow reducing the number of connecting lines between the transmitter and the receiving unit, reducing the number of guard guards and increasing the reliability of guarding objects.
