基于NPort串口服务器的座椅滑道装配线监控系统

A monitoring system of assembly line for seat-track based on NPort serial communication server

为了解决座椅滑道装配线中各个独立工位的运行状态监控问题,采用了NPort串口服务器的形式进行各控制器的联网,介绍了串口服务器的发展过程、结构和设计原理,分析了滑道装配线的组成和装配工艺,分析了串口通讯时的通讯参数和自定通讯协议的构成,介绍了LabVIEW软件的功能和MX-Component模块的作用,提出了上位机监控软件的主体结构,设计的软件经过调试后能够稳定运行,实际使用结果表明,串口服务器可以很好地解决由独立工位构成的装配线中各控制器的联网监控问题。

In order to monitor the running status of each single station in the assembly line for seat-track,the NPort communication servers were utilized to connect each controller.The development,structure and design principle of the communication server were introduced.The composition and assemble process of the seat-track assembly line were analyzed.The communication parameter and the composition of the communication protocal were analyzed.The function of the LabVIEW software and the operation of MX-Component module were introduced.The main structure of the computer monitoring software was presented,and the designed software can run stably after debugging.The result shows that the communication server can solve the network connection problem of each independent controller well in assembly lines composed by single stations.
