应用ZigBee技术的纬编生产数据实时采集系统

摘要

针对纬编企业生产过程复杂，生产数据记录需要人工统计且滞后，数据可靠性差、不稳定，信息反馈不及时，效率低等问题，采用ZigBee技术开发了包括数据采集模块和数据接收与处理模块2部分的纬编生产数据实时采集系统。分别从硬件和软件设计2个方面探讨了数据采集模块的基本架构，并通过对数据表的设计、通信协议的修订、程序的修改等分析设计了数据接收与处理模块。将该采集系统投入到某公司试用，并把采集的数据与实际数据进行了对比。结果表明，ZigBee技术实时性好，稳定性高，传输方便可靠，系统的数据采集误差较小，满足了纬编车间的数据采集要求。%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 analyzed 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 comparison the collected data with actual data that the ZigBee technology can transmit data with stability, convenience and reliability, and the data error is very small, which satisfy the data acquisition requirement of weft knitting.
