A Design of Wireless Monitoring System for Circular Knitting Machines Based on ZigBee

This monitoring program transmits data and realizes the real-time monitoring of each circular knitting machine by wireless network instead of the traditional wired network. Based on the ZigBee technology, the wireless sensor network in the program is constituted by ordinary sensor node, the sink node and network coordinator, and responsible for acquiring and transmitting condition information of circular knitting machines. This paper has described the network structure and nodes´ hardware structure of the program and discussed the communication processes of the ZigBee modules.
