Abstract

The invention relates to a man-machine latch-up protection system in coal mine digging work area. The latch-up protection system is based on the detection principle of a pyroelectricitic sensor and is capable of monitoring the operation dangerous areas of a loading machine on a coal face and an entry driving machine on a driving face through the reasonable installation and configuration of infrared sensors and a complete set of devices. If anyone enters the areas, the latch-up protection system gives off an alarm and simultaneously outputs a latch-up control signal, cuts off a power supply immediately, and stops the running of the loading machine or the entry driving machine or forbids the machines from running, thereby better ensuring the safety of the personnel in the digging work area, and effectively avoiding the bodily injury accidents in the coal face loading machine operation area and the driving face entry driving machine operation area. The system adopts the infrared detection technology and corresponding devices and does not give off any type of radiation. The system has the low power consumption of devices, good invisibility, and a low price. When the latch-up protection system is installed and put into use, the latch-up protection system puts an end to the unnecessary injury caused by manual operation errors, improves the reliability of mechanical injury protection in the corresponding areas, and realizes the intrinsic safety of the corresponding areas.

Description

Technical field: [0001] The invention relates to a safety protection system for a coal mine, in particular to a man-machine locking protection system for a coal mining working area. Background technique: [0002] In recent years, with the continuous investment of large-scale machinery and equipment in coal mines, the degree of mechanization of coal mine production has become higher and higher, and accidents involving coal mine machinery and equipment have also occurred continuously. The reasons are mainly as follows: ①The safety facilities are not complete, and the preventive detection and inspection system is not perfect; ②The safety design of the equipment is flawed; Workers, inexperienced personnel, and those who do not concentrate; ④ Incomplete investigation of safety hazards at the production site; ⑤ Inadequate safety management; ⑥ Illegal command, illegal operations, and illegal operations; Wait. In addition, the harsh working environment underground, highly stressfu...
