Design of wireless Andon system based on ZigBee

This paper presents a wireless Andon system based on Zigbee. The system realizes wireless transmission of Andon information in special construction lines and has some functions including production monitoring, wireless calling and statistics report. Radio frequency technology of ZigBee is adopted by the system to realize wireless communication. Users can accurately convey demand information from Andon calling devices to Kingview PC center and relate staffs under noisy environment of production line. This system effectively solves the flexibility problems of traditional Andon system in the changeable and special lines. Moreover, it has good scalability. By practical test, the system is capable of meeting production requirements well with good reliability and security in the environment of workshops and it also has a good application prospect.
