Designs of Wireless Monitoring Network System of Mill

In this paper, sensors, which are directly installed on the surface of the mill, are used to collect mill´s signals by wireless. The frame of the system is introduced and the hardware and software is designed in details in this paper. With the transmission mode of I²S and MCU of AT89S2051, the transform from analog signals to digital signals , data´s transmission by wireless is achieved by this system. On this basis, the program designed is not only good at collect mill´s signals, but also restraining the interference, analyzing spectrum. So the program can effectively achieve the mill state detection.
