Abstract

The invention relates to the mining industry and is intended for teleautomatic, centralized and continuous functional monitoring of the operation of automatic protection equipment. The goal is to expand the functionality by providing control of various parameters and connecting emergency equipment (AO) in the switching collectors. The device comprises a control panel connected to the status 2 process equipment detectors. The control panel consists of a time relay (PB) 6, a mnemonic circuit 3, a control cell 1 according to the number of signaling devices 2, an electronic key 4, a light and sound alarm unit 5 and a relay AO 7. Mnemonic scheme 3 is made on the gas and control voltage LEDs of the detectors 2. The signals from the cells 1 are fed to the input of the key 4, one of the outputs of which is connected to the node 5 of the light and sound alarms, and the other output is connected to the PB 6. Electrically the PB 6 is connected relay 7. When a signal appears on one of the detectors 2, the corresponding cell 1 outputs a signal to the corresponding LED of Mimic 3 and to the control input of key 4. After opening, key 4 turns on node 5 and PB 6. After some time PB 6 gives a command to Relay 7 on AB. 2 Il.

The purpose of the invention is to improve the functionality by controlling various parameters and connecting emergency equipment in / switching collectors.

FIG. i represents the structural scheme of the device; in fig. 2 - execution of the control cell of the connection with the mimic diagram and signaling devices of the process equipment.

The device contains control cells 1, electrically connected with signaling devices 2 of the state of the process equipment 5 technology, located outside the device (in the KauHcsiiHOM communal collector) to the device 3. The signals from the cells are monitored at the input of the electronic switch 4, one of the outputs of which is connected to the light and sound alarm node 5, and the other output is connected to the time relay 6 electrically connected to the relay equipment 7. The power supply unit 8 with the output is stabilized. The power supply voltage of 12 V is electrically connected with all the units of the ycTpoficTna technological control: who is equipped.

The device works as follows.
