生产状况的实时显示对于提高企业的生产效率具有十分重要的意义。针对目前生产车间采用PLC进行自动化控制,但现场却不能使用LED显示屏进行实时显示的问题,这篇文章设计了一套生产现场显示系统,同时采用STM32微控制器开发LED控制卡,与PLC进行自由口协议的通信,即可将现场的生产数据在集控室的上位机上进行显示查询,又可将PLC采集的生产数据实时的显示在现场的LED显示屏上,为生产调度提供有效依据。
The real-time display of production status is of great significance for improving the production efficiency of enterprises. For the current production workshop using PLC for automatic control, but the scene can not use the LED display for real-time display problems, this article designed a production site display system, using STM32 microcontroller development LED control card, and PLC Freeport agreement communication, you can field production data in the control room on the host computer to display queries, but also the PLC production data collected in real-time display on the scene of the LED display, to provide an effective basis for production scheduling.
