Problems solved by technology

[0004] The purpose of the present invention is to provide a methane electric blocking function test method, which is used to solve the problem that the current methane electric blocking function test cannot ensure that the equipment switches related to the methane sensor are all in the energized state, resulting in the invalidity of the methane electric blocking function test and potential safety hazards. At the same time, a methane electric locking function test system is also provided, which is used to remind the background staff of the status of the equipment switch in real time, so as to avoid potential safety hazards; at the same time, a methane electric locking function test system is also provided. Real-time reminder to inform the underground field staff of the status of the equipment switch to avoid potential safety hazards

Embodiment 1

[0025] A kind of methane electric blocking function test system of the present invention, as figure 1 As shown, the test system includes the first monitoring substation, the second monitoring substation and the host computer. Both the first monitoring substation and the second monitoring substation are connected to the host computer through the underground ring network system. The first monitoring substation corresponds to The first methane sensor is connected, and the device switch associated with the first methane sensor includes a first device switch and a second device switch. The first monitoring substation is also connected with a first power-off feeder and a second power-off feeder. A power-off feeder is used to be correspondingly arranged at the first device switch associated with the first methane sensor, and a second power-off feeder is used to be correspondingly arranged at the second device switch associated with the first methane sensor, and The first cut-off feed...

Embodiment 2

[0034] The present invention also provides a methane electric locking function test system, such as figure 2 As shown, the test system includes a first monitoring substation and a second monitoring substation. Both the first monitoring substation and the second monitoring substation are connected to the underground ring network system. The first monitoring substation is correspondingly connected to the first methane sensor. The first monitoring substation is also connected with a first power-off feeder and a second power-off feeder, the first power-off feeder is used to be correspondingly set at the first equipment switch associated with the first methane sensor, and the second power-off feeder The electric feeder is used to be correspondingly arranged at the second device switch associated with the first methane sensor, and the first power-off feeder is connected to the first device switch associated with the first methane sensor, and the second power-off feeder is connected ...

Abstract

The invention provides a method and system for testing the methane electric blocking function. When testing the methane electric blocking function, it is first judged whether the methane sensor is in the calibration state; If the switch of the equipment controlled by the sensor is in the power-off state, an alarm will be issued to remind the relevant testers to stop the test, which ensures that the on-site testers can always conduct on-site tests when the switch of the equipment is powered on, and avoid potential safety hazards.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, and in particular relates to a method and system for testing the methane electric locking function. Background technique [0002] In order to prevent gas accidents and ensure safe production in mines, gas and electric locks and wind power locks must be installed in the coal mine production process to disconnect all non-intrinsically safe electrical equipment in the tunneling roadway or coal mining face when the gas exceeds the limit. For example, the Chinese utility model patent document with the authorized announcement number CN204357487U discloses a mine wind power and gas power lock control system, which includes a monitoring substation, a vacuum feed switch connected to the monitoring substation, and a gas sensor And circuit breakers, etc., to disconnect the power supply of all non-intrinsically safe electrical equipment associated with the gas sensor in the area when the gas exceeds...
