上海地铁5号线报站器可扩展HMI的设计与实现

Design and implement the HMIof Shanghai Metro Line 5 station announciator

利用MFC中的串口通信技术,设计一种上海地铁5号线报站器的可扩展人机接口(HMI)。通过报站器内部简单的可扩展设计,将显示菜单的数据储存在掉电数据不丢失的EEPROM中。使用RS232串口通信,结合PC机端的用MFC开发的上位机软件,无需对报站器控制芯片的代码进行任何修改,即可由用户自己通过简单的PC机端的操作实现报站器操作界面的改动。

This article is abort using MFC serial communication technology, and design a Shanghai Metro Line 5 stop the ex- pansion of man-machine interface （HMI）. Simple scalability stop internal design of the menu structure, the menu display data is stored in the EEPROM in which the data is not lost when power-down. Use RS232 serial communication, the PC side, the PC software developed using MFC, without stop control chip code to make any modifications to the user through a simple operation of the PC side, to achieve the stoo control operation interface changes.
