摘　　要：针对目前煤矿井下用风速传感器数据传输的模拟单向性问题,设计了一种基于CAN总线机制进行数据传输的超声波旋涡式风速传感器。利用μC/OS-Ⅱ的实时抢占式机制以及任务调度机制,保证传感器数据传输的实时性以及响应命令的高效性。试验结果表明,该传感器测量误差较小,响应时间较低,数据传输可靠,抗干扰性强。Aiming at data analog transmission problem of wind speed sensor in coal mine, , we design a kind of wind speed sensor with ultrasonic vortex type based on CAN bus mechanism for data transmission. The real-time preemption mechanism and task scheduling mechanism of the μC/OS-Ⅱ are used to ensure the real-time transmission of sensor data and the high efficiency of the response command. The experiment shows that the sensor has the advantages of small measurement error, low response time, reliable data transmission and strong anti-interference.
