0 概述信号系统是变电站和生产流程中不可缺少的部分。长期以来,光字牌式的传统型信号系统一直在各种场合占有主导地位。它具有运行方式简单、结构直观等优点。然而,由于它全部由各种继电器、光字牌(指示灯)组成,具有维护量大、占地面积大、难以实现综合自动化等弊端。随着微电子技术和微处理器(单片机)技术的发展,我们对原有信号系统进行了改造,开发出一种全新
0 Overview Signal systems are an integral part of substation and production processes. For a long time, the conventional optical signal system has dominated various occasions. It has the advantages of simple operation, intuitive structure and so on. However, due to its all kinds of relays, light plate (light) composition, with a large amount of maintenance, covers an area of large, difficult to achieve comprehensive automation and other drawbacks. With the development of microelectronic technology and microprocessor (single chip microcomputer) technology, we have rebuilt the original signal system and developed a brand new
