Design and application of coal mine hydraulic support pressure sensor based on wireless Mesh Ad-Hoc network
By research the application of hydraulic support sensors in existing wireless mine pressure monitoring systems,it's fowd that it always exists unstable data transmission and high sensor power consumption problems.This paper introduces a kind of coal mine hydraulic support pressure sensor based on wireless Mesh AD-Hoc network,to overcome the problems of unstable data transmission and high sensor power.It takes STM32L412 microcontroller as the core processor,regularly collects pressure data of hydraulic supports,process and stoves the pressure data,and controls the data transferred through the wireless Mesh network to the substation,the pressure data finally reach the ground system.The design combines Mesh module wake-up mechanism with STM32L412 microcontroller low-power mode to ensure data transmission reliability while also considering the low power consump-tion of the sensor.After on-site practical application,the hydraulic support pressure sensor has achieved the design goals in terms of network data transmission and low power consumption in the coal mine underground environment,it is suitable for pressure col-lection and monitoring of hydraulic supports in coal mining face.
