An ultrasonic ranging system with STC12C5A60S2 MCU as the core controller is designed

multi sensor technology and GPRS wireless communication technology. The system can be used to measure the distance through the two transmission modes of wired and wireless

and the host computer monitoring interface is developed by using LabVIEW

which can monitor the distance and temperature simultaneously

and has the alarm function. The measured data is automatically stored in the form of Excel

which is convenient for subsequent analysis. At the same time

the relevant field test is done

and the data analysis and error analysis are carried out. The results show that the system can achieve ranging function effectively and has a certain measurement accuracy.
