闭锁逻辑解析在电脑钥匙软件设计中的应用

用电脑钥匙执行操作票是微机防误操作中最为核心和关键的部分,也是电脑钥匙软件设计的难点。通过对各种不同电气设备防误闭锁方法的研究梳理,解析出几个基本的闭锁和状态检测操作元素。以基本操作元素为基础,构建各种设备操作过程的逻辑描述表达式。采用结构程序设计的方法,按照表达式的逻辑要求进行软件设计,能够较好化简程序,满足五防电脑钥匙在操作票执行过程中对任何设备解闭锁操作方式的要求。

Application of Lockout Logic Analysis in Computer Key Software Designing

Using computer key to execute operation is the core of microprocessor-based anti-misoperation system, and is also the difficult part in designing the system. Through an investigation of anti-misoperation and lockout systems for various electrical devices, several basic operational operation units for lockout operation and state detection are pointed out. Based on the basic operational operation units, logic relationships between operational steps of various electrical devices, as well as corresponding expressions, are established. Module type based program designing method and logic relationships between operational steps of various electrical devices can simplify the process of sotb,vare development, and satisfy the requirements of any electrical devices＇ operation.
