摘　　要：针对在钻探过程中,无法直接获取水泵出水口位置的流量传感器数据问题,根据需求设计了基于nRF24L01无线模块的无线数据传输方式,并通过铜制滑环接触供电。详细介绍了系统在复杂环境下流量数据的采集、传输工作情况,分析并验证了水泵的流量和出水口压力之间的关系。采用STM32C8T6作为微控制器,给出了软硬件设计思想和可靠的无线连接数据传输技术。A wireless data transmission mode based on nRF24L01 wireless module is designed to overcome the difficulty that the flow sensor data at the pump outlet can not be obtained directly in the drilling process. In the design,a copper slip ring is adopted to achieve the power supply. The flow data acquisition and transmission of the system in complex environment are in-troduced in detail. STM32C8T6 is taken as a microcontroller in the system. The relationship between flow and outlet pressure of the pump was analyzed and verified. The software and hardware design ideas and reliable connectionless data transmission tech-nology are offered in this paper.
