Abstract: Abstract:According to the strong mechanical vibration source in the mine and the special environmental condition of inconvenient replacement of the power supply line, a self-powered underground temperature acquisition terminal node with long service life is designed. Power generation part of the use of magnetoelectric dual-mode power to collect energy together to achieve self-powered energy by the lithium battery added; chip LTC3331 energy management to achieve the entire system power to CC2530 8051 core for the control center, the temperature sensor DS18B20 control Terminal data acquisition and MAX17043 for power detection, and finally through the CC2530 RF module will send data to the host interface. Finally, the experimental results show that the designed structure is effective and the collected data truly reflect the ambient temperature. Improve the system monitoring the life and accuracy, can effectively prevent the occurrence of failure.
