Abstract: This research focuses on the single hydraulic prop of the well. Using the chip Z1000 and chip SH79F166, the wireless communication module based on the ZigBee wireless sensor network technology and the main control module based on embedded technology are designed respectively. And a safe power supply circuit module is designed. Through the field test, the design can satisfy the requirement of the validity and reliability of data acquisition, and the power consumption is low, and the transmission quality of information monitoring is high. The pressure value of the downhole hydraulic prop can realize real-time monitoring and alarm, reduce the accident rate, and can actually be used in underground safe production.
