摘　　要：为了测量机械设备中油膜的厚度,基于超声波反射系数法设计了一种超声膜厚测量系统。在μC/OS-II操作系统基础上实现一定的人机交互功能以及上位机串口控制功能,完成了模拟静态油膜结构的测量。测量结果的相对误差在5%以内,证明了超声膜厚测量系统的可行性。To measure oil film thickness in mechanical equipment,an ultrasonic film thickness measurement system is designed based on ultrasonic reflection coefficient method.The certain human-computer interaction function on the basis ofμC/OS-II and serial port control function of the host computer are implemented in this system,and the measurement of the simulated static oil film structure is completed.The relative error of the measurement results is less than 5%,which proves the feasibility of the ultrasonic film thickness measurement system.
