摘要
介绍选用ＳＴＤ总线设计变电站微机运动装置的硬件结构，软件设计方法及可靠性措施．设计中采用了自恢复、自诊断、软件滤波、硬件滤波及光电隔离等多种抗干扰措施，解决了同类装置经常出现的死机及运行不稳定的难题．装置具有小型化、组合化、模块化、标准化等特点．
How to use STD bus to design the hardware structure, the software approach, and the reliability measures of a microcomputer remote terminal unit in a substation is the main point in this paper. To improve the ability of resisting interference, the measures of self-healing, self-diagnosing,software filtering, hardware filtering, and light-electric segregating, etc., are used in the R&D. The measures are also used to solve some problems, such as, deadlock and unstable running, which usually take place in some similar units. The charecteristics of the unit are small-sized, assembled, blocked, and standardized, etc.
