Abstract:

In order to resolve the issues of the complex production process of weft knitting, the matter that production data needs manual record, and the trouble that data is poor reliability, low efficiency, we have developed weft knitting real-time data collection system using ZigBee technology. The system includes data collection module, the data receiving and processing module.This paper not only have discussed the basic architecture of the data collection system from hardware design and software design, but also analysised the data receiving and processing module from design of the database, communication protocol and program modification.The system has realized the real-time data collection and two-way transmission of weft knitting, ensured the accuracy of the data, offered the technical foundation for the weft knitting manufacturing execution system. Finally, the system has been put into a company, and it is found by compared the collected data with actual data that the ZigBee technology can transmit datd with stability, conwenient and reliable, and the data errror is very small, which satisfy the data acquisition requirement of weft knitting.

Key words: weft knitting, ZigBee technology, real-time data colection, manufacturing execution system
