文中深入分析了备用电源自动投入(简称备自投)的特点——由多个步骤环节组成且每个步骤环节有不同的条件状态,因为备自投实质是一种基于时序控制的过程,不同的运行方式条件差异很大。提出一种基于有限状态机(FSM)和组态的备自投实现方案,能够解决时序控制过程和条件差异,通用性强。该方案由若干个输入部件和输出部件、1个有限状态机和组态文件组成,通过“搭积木”方式实现完全任意组态的备自投,以及各种复杂情况的备自投,能够方便工程维护,提高开发效率。
The article deeply analyzes the characteristics of the automatic standby power supply (referred to as prepared by the vote) - composed of multiple steps and each step has a different condition, because the backup is a real time based on the timing control of the process, different The operating conditions vary widely. A scheme based on finite state machine (FSM) and configuration is proposed. It can solve the difference of timing control process and conditions, and is versatile. The program consists of a number of input components and output components, a finite state machine and configuration file, through the “building blocks ” way to achieve completely arbitrary configuration of the self-vote, as well as a variety of complex situations, To facilitate project maintenance, improve development efficiency.
