Abstract: We designed a new type of intelligent drilling bed-separation monitoring system, which uses the power supply mode of solar panels and applies GPRS wireless communication technology to the system. The system adopts the intelligent sensor to collect the displacement of the bed-separation. The collected information is transmitted to the microprocessor STM32F103RCT6 via the M-bus. After the further process of the information, it is transmitted to the monitoring and calculation through the GPRS wireless communication. Monitoring computer can display real-time monitoring data of bed-separation, and can realize wireless monitoring of drilling bed-separation and alarm function.
