矿井液压支架压力无线监测装置的研究

his article is aimed at the coal mine hydraulic support more monitoring points,the monitoring points often moving the characteristic,and designs a set of mine hydraulic support pressure monitoring device.This design uses the Freescale Semiconductor company to produce the internal integrating 16 bit A/D converter,containing the Cortex-M0+ ARM processor MKL15Z64VFT4 single chip microcomputer,and carries on the real-time monitoring to the 2 way hydraulic support,and the wireless transmission data.The data acquisition circuit,wireless communication circuit and peripheral power supply control circuit are designed, and the hardware and software power saving design of the system and the design of wireless data transmission and anti collision are carried out, which ensures the reliable operation of the system.
