| Abstract: | 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. |
