Mining intrinsic safety type micro-power-consumption wireless and wired communication self-powered pressure sensor

Abstract

The invention discloses a mining intrinsic safety type micro-power-consumption wireless and wired communication self-powered pressure sensor. The mining intrinsic safety type micro-power-consumption wireless and wired communication self-powered pressure sensor mainly comprises a pressure sensor body, a pressure acquisition processing unit, an MCU processor, a switching processing unit, a display unit, an RS485 communication processing unit, an external bus communication unit, a wireless receiving and transmitting unit, an internal battery unit, an intelligent power source switching, conversion and management unit and an external power supply unit. Current pressure is measured through the pressure sensor body, the acquisition processing unit and the MCU processor and displayed through the display unit, a sensor power switch is controlled through keys and a Hall sensor, and a sensor power source and electricity saving are managed through the power source switching, conversion and management unit. Data are transmitted in a wireless mode and in a wired bus mode. According to the pressure sensor, a method and design are advanced and scientific, the gap of the mining intrinsic safety type micro-power-consumption wireless and wired communication self-powered pressure sensor is filled in, and the pressure sensor has the advantages of being high in integration degree, safe, reliable and the like.

Description

technical field [0001] The present invention relates to a mine-used intrinsically safe micro-power consumption wireless and wired communication self-powered pressure sensor, specifically a pressure sensor with high integration, dual-path transmission, low power consumption, self-contained display screen, and no external power supply Pressure Sensor. Background technique [0002] Many mine pressure data such as mine pressure observation, initial support force of hydraulic support and current pressure value of hydraulic support have always been indispensable and important data for coal mine production. However, due to the complex terrain, harsh environment, and numerous equipment and pipelines in coal mines , Acquisition of pressure data has always been a problem that has not been perfectly and effectively solved. The use of traditional mechanical pressure gauges can only achieve simple data observation, and cannot effectively obtain pressure data. The use of wired pressure s...
