Abstract: Deep geothermal energy is the energy treasure of social development and construction. In order to meet the technical requirements of deep geothermal energy exploration, a deep well thermometer and its compensation control system based on enhanced 51 single chip microcomputer are designed. The system is supplemented by power supply module, display module, wireless transceiver module, coil unwinding control module and end temperature sensor. The temperature physical quantity collected by temperature sensor can be converted into visible digital quantity by using A/D conversion module, which can be read out accurately on the display module. The compensation circuit can effectively reduce the measurement error caused by pressure drop, and can accurately measure the temperature value of each observation point, so as to effectively complete the accurate monitoring and analysis of deep geothermal energy. The system hardware test results show that the system has accurate temperature measurement and rich functions, which has a certain application value.
