摘　　要：液晶显示器与高性能的RabbitCore RCM2200型模块配合使用,可以组成继电保护装置的人机界面接口(MMI)模件,该模件主要负责显示和修改保护CPU的信息。重点介绍了RabbitCoreRCM2200型模块与内置T6963c控制器的VPG12864T液晶模块的实用接口硬件设计,给出了直接控制方式及接口电路;利用RCM2200模块的特点,即E口实现数据的读、写操作。RCM2200模块的程序设计采用Z-World公司的编译软件DynamicC编程,给出了VPG12864T液晶显示模块写参数命令的流程图。显示的汉字是以标准16×16字库为基准,选取MMI模块界面所要应用的汉字,生成一个新的精简汉字库,给出了生成汉字库格式及屏幕显示汉字的流程图。所设计的接口可行、高效。The MMI（Man Machine Interface） of relaying protection,composed of LCD（Liquid Crystal Display） and high-performance RabbitCore RCM2200,is used to display and modify the information of protection CPU. The hardware design of the interface between RabbitCore RCM2200 module and VPG12864T LCD module with embedded T6963c controller is introduced with circuits and its direct control mode is presented. Read and Write operations are implemented using port E of RCM2200. The software of RCM2200 is programmed with Dynamic C of Z-World Corporation and the flowchart of VPG12864T parameter setting is presented, The Chinese characters are displayed in 16×16 pixels and the Chinese character base is generated by selecting the Chinese characters needed. The structure of Chinese character base and the flowchart of Chinese character display are proposed. The designed interface is feasible and efficient.
