摘要:

传统继电保护装置显示终端软件常常随保护装置本体软件升级或非标需求进行相应修改,为了满足保护装置显示终端通用性要求,提出一种通用性保护装置显示终端的设计与实现方法。基于该方法设计的显示终端,采用独立的中央处理器(CPU),自带字库文件,界面图形可脱离代码编写直接绘制。该显示终端程序软件架构分为两大任务,基于邮件方式的界面服务处理任务和基于RS-232串口的与保护装置本体通信任务。此显示终端不依赖保护装置本体,既不限定硬件平台,也不限定主机程序,具有通用性。测试结果和某10kV配网配电终端的成功运行证明了该显示终端用于保护装置的正确性和实用性。

Abstract:

Traditional display terminal for relay protection devices are often modified with the upgrading of software and nonstandard requirements. In order to meet the universal requirements of the display terminal, a design and implementation of a universal display terminal for protection devices is proposed. The display terminal based on the design above, whose interface graphics can be drawn directly without code writing, adopts independent CPU and has its own fonts files. There are two major tasks under the terminal programs software framework, which are interface service processing based on mailing and communication with protection device based on RS-232 serials. This display terminal has versatility in application, and it neither relys on protection device, nor be restricted by hardware platform or applications. The correctness and practicability of the display terminal has been proved by the successful trial in the distribution terminal of a 10kV distribution network.
