基于PLC远程I/O的汽车装配线生产信息系统的应用

Auto assembly line producing informationg system application based on PLC long-distance I/O

针对汽车装配线生产信息采集和管理的实际需求,提出了一种基于PLC远程I/O的解决方案,并给出了具体实施措施。利用SIEMENS S7-200、S7-300PLC和IPC、LED大屏幕组成装配线生产信息系统,实现装配线上各工位申请求助、申请停线故障报警信息及装配线生产节拍、年月日生产计划、当前完成情况等生产信息显示,以便于故障及时排除和生产状况的动态掌握。系统信息采样及时、信息显示直观、信息保存完整。

To meet the practical demand of collecting and managing producing information in auto assembly line, the paper gives the solution based on PLC I/O and practical implement measures. In order to remove the fault on time and master the dynamic of producing condition, we can receive the help signals from every workplace in assembly line, apply for display of the alert information of Stagnation fault, the producing time in assembly line, the yearly monthly or daily producing plan, and producing information of current schedule, by using of assembly line information system consisted of SIEMENS, S7-200, S7-300PLC, IPC, LED screen. According the system mentioned in the solution, we can pick up system information in time, display information intuitively and save information perfectly.
