Mine Wireless Proximity Sensor Switch

Abstract

The invention provides a mine-used wireless proximity sensor switch, which includes a power conversion module, a wireless communication module, a main control module, an execution module, a setting module and an indicator light module; the voltage conversion module converts alternating current into a direct current working power; the wireless communication module uses Receive the personnel positioning identification card information carried by the mine staff at all times and transmit it to the main control module in real time; the main control module processes the received information and correspondingly controls the power supply of the controlled electrical load through the execution module. The invention can be effectively applied to the harsh working conditions of coal mines, is convenient to use, is safe and reliable, and can automatically and accurately judge the distance between a mine worker carrying a personnel positioning identification card and a switch, and controls the power on and off of the controlled electrical load accordingly.

Description

technical field [0001] The invention relates to the technical field of electrical control switches, in particular to a mine-used wireless proximity inductive switch for controlling a load power supply, which is suitable for harsh working conditions such as underground coal mines. Background technique [0002] There can 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 is a person or not. In response to this problem, many coal mining enterprises have carried out energy-saving transformation of the lighting in the coal mine, generally by installing an infrared sensor switch to control the lighting and extinguishing of the lighting. When the infrared sensor switch detects the infrared light emitted by the human body, the control light is turned on, and the control light is extinguished when the mine staff leave the distance range that the infrare...

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
