Description

 The invention relates to the mining, mining industry, as well as to communication collectors, in particular to devices transmitting a gas protection signal.

 Due to the fact that in similar known devices and systems, for example, in a device according to ed. USSR N 390674 only a telephone line is used without communication with the city automatic telephone exchange, which does not allow the transmission of data over long distances, since connection via the city automatic telephone exchange is required.

 The closest solution to the technical nature and the achieved result is a control and monitoring system for the transmission of commands over telephone lines by auto. USSR N 1338109.

 The disadvantages of this system are the impossibility of fully automating the process of transmitting gas protection data to the dispatcher console and, in addition, when using the above system, it is not possible to receive telealarm systems from various controlled points that are possible when using the proposed system.

 The aim of the invention is the complete automation of the process of transmitting data signaling gas protection.

 This goal is achieved in that the gas protection tele-alarm data is transmitted by introducing an automatic gas protection into the system, connected via a memory unit to a generator, which is connected via an timer and telephone line to an automatic telephone exchange, the output of which is connected via a telephone line to a pipe lift simulator , a time relay, a band-pass filter unit and a memory unit with an input of a mnemonic circuit, the output of which is connected via an "OR" element to an audible alarm unit, in addition, The subscriber connectivity analyzer is connected to a digital dialer and a telephone line.

 The present invention has significant differences, since the use of the proposed automatic system with automatic gas protection introduced into it, two memory units, a subscriber connection analyzer, a digital dialer, an additional time switch, a bandpass filter unit, an OR element and an audio signaling unit allows transmitting tele-signaling data via telephone communication automatically to the dispatcher console.

 The invention is illustrated in the drawing, where in FIG. 1 shows a functional diagram of an automatic system.

 The present invention is an automatic system for transmitting a telealarm system over telephone lines, including automatic gas protection 1, a memory unit 2, a generator 3, a timer 4, a subscriber connection analyzer 5, a digital dialer 6, an automatic telephone exchange 7, a tube pickup simulator 8, a time relay 9, a bandpass filter unit 10, a memory unit 11, a mimic diagram 12, an OR element 13, and an audible alarm unit 14.

 The signal about the operation of the automatic gas protection equipment 1 is supplied through the memory unit 2 to the input of the generator 3, connected through the make contact of the time relay 4 to the telephone line. The telephone line is connected to the input of the subscriber’s connection analyzer 5, the first output of which is connected to the second input of the time relay 4, and the second to the first input of the digital dialer 6, in addition, the output of automatic gas protection 1 through the memory unit 2 and the digital dialer 6 is connected to the telephone line entering the city automatic telephone exchange 7. Similarly, other gas protection devices, which may be N, are connected to the automatic telephone exchange 7. The output of the automatic telephone exchange through a telephone line is connected to the input of the tube lift simulator 8 and through the make contact of the time relay 9 is connected to the input of the bandpass filter unit 10, the output of which is connected through the memory unit 11 to the mnemonic circuit 12 and through the OR element 13 to the audible alarm unit 14.

 In the presence of gas, automatic gas protection equipment 1 is triggered, from the output of which the alarm signal is stored in the memory unit 2 and fed to the generator 3 and digital dialer 6, which generates subscriber call signals. If there is a free telephone line, subscriber connection analyzer 5 starts time relay 4, which connects generator 3 to the telephone line for 30 s. When the telephone line is busy, the signal from the subscriber’s connection analyzer 5 starts the digital dialer 6 again until the telephone line is free. The tonal purity corresponding to this automatic gas protection equipment from generator 3, passing through the telephone line and the automatic telephone exchange 7, enters through the make contact of the time relay 9 to the input of the bandpass filter unit 10, and the time relay 9 for 30 s is connected by a tube raising simulator 8, triggered when a caller receives a call signal. At the output of one of the band-pass filters 10, a signal is allocated corresponding to a certain automatic gas protection apparatus 1, which is stored by the memory unit 11, the corresponding LED lights up on the mimic diagram 12, and the signal through the OR 13 circuit is fed to the audible alarm unit 14.
