For the long?distance industrial monitoring and control,an angle measurement system based on Ethernet is de?signed. Compared with the traditional RS232 and RS485/422 communication interface,Ethernet interface has the advantages of low cost and easy networking,which is convenient to realize enterprise integration management. According to the working princi?ple and characteristics of the MEMS accelerometer sensor,a realization method of angle measurement system based on MEMS accelerometer sensor and the smallest Ethernet chip is studied. The working principle of the system is introduced. The hardware circuit design and software design of the system are expounded emphatically. The software for microcontroller and the PC real?time display software based on UDP communication protocol were compiled and tested in experiment. The experimental results show that the system has high integration,low power consumption,high reliability,and can be used for a variety of long dis?tance attitude measurement. Compared with the conventional angle measurement system,the system has characteristics of high measuring accuracy,large measuring range,and is convenient to carry and use.
