摘要
为实现对光伏并网发电系统的操作和实时监控,分析了应用于工业控制的Modbus通信协议,介绍了TPC7062K型号的触摸屏,利用MCGS组态软件完成了触摸屏控制界面的设计。以触摸屏作为主机,DSP作为从机,实现了两者之间基于Modbus协议的串口通信。通过实验验证:系统运行过程中,数据传输稳定可靠且实时性好,实现了良好的人机交互控制。
To achieve the operation and real-time monitoring to the grid-connected PV system, the Modbus communication protocol applied in industry control was analyzed, and the TPC7062 K type of touch screen was introduced. The touch-screen control interface was designed through using the MCGS configuration software. The master was touch-screen, and the slave was DSP. In addition, serial communication between the two was realized based on Modbus protocol. The related experiment shows that the data transmission communication system is stable, reliable, high real-time and can be used for man-machine interactive control in the running process of the system.
