Mining wireless proximity inductive switch

Abstract

The invention provides a mining wireless proximity inductive switch. The mining wireless proximity inductive switch comprises a power converting module, a wireless communication module, a master control module, an executing module, a setting module and an indicator light module. The power converting module converts alternating current into a direct-current working power supply. The wireless communication module is used for receiving information of a personnel positioning identification card carried by a mine worker in the using process and transmitting the information to the master control module in real time. The master control module processes the received information and controls the on-off state of a power supply of a controlled electrical appliance load through the executing module. The mining wireless proximity inductive switch can be effectively applicable to severe working conditions in a coal mine well, is convenient to use, safe and reliable, and can automatically and accurately judge the distance between the mine worker carrying the personnel positioning identification card and the switch, so that the on-off state of the power supply of the controlled electrical appliance load is controlled according to the judged distance.

Description

Technical field [0001] The invention relates to the technical field of electrical control switches, in particular to a mine-used wireless proximity sensor switch suitable for harsh working conditions such as underground coal mines for controlling load power supplies. Background technique [0002] There must be no lack of lighting in coal mines. However, the traditional underground lighting in coal mines usually implements uninterrupted lighting 24 hours a day, regardless of whether there are people or no one. The electricity consumption is huge, which wastes electricity and also increases the cost burden of coal mine enterprises. In response to this problem, many coal mine enterprises have carried out energy-saving transformations to the underground lighting of coal mines. Generally, infrared sensor switches are installed to control the lighting and extinguishing of the lights. The working principle is that when there are underground workers approaching When the infrared sensor ...

AI Technical Summary

Problems solved by technology

Although this kind of infrared induction switch has a certain energy-saving effect, it also has obvious deficiencies in the use process: in the harsh working environment of the coal mine, the infrared induction switch is easily affected by various heat sources, light sources, radio frequency radiation, thermal radiation, etc. The interference of airflow, etc., especially when the ambient temperature of the coal mine is close to the body temperature of the human body, the working sensitivity of the infrared sensor switch is significantly reduced, the working reliability is greatly reduced, and even the lighting is often turned off by interference, which will bring losses to production and cause safety hazards ; and it usually only detects moving objects, and cannot be detected when the human body movement is not large
