单片机仿真64D半自动继电逻辑关系

SCM Simulation of 64D Semi-automatic Block Logical Relationship

根据64D半自动闭塞的工作原理及办理过程,研制开发出一种用单片机完成64D继电半自动闭塞功能的系统。通过分析继电半自动闭塞所有逻辑关系,找出所有的触发条件。每个触发条件对应一个软件处理模块,画出相应的软件处理模块程序框图。在判断13个继电器状态时,根据实际情况减少判断继电器的数量,简化判断条件,既简化了软件开发,又降低了不确定性。

According to the working principle and operating process of 64D semi-automatic blocks, one SCM-based system which could conduct the functions of 64D relay semi-automatic block was developed By analyzing all the logical relationship of the relay-based semiautomatic block, all the can be identified. Each triggering event can be modeled as a software processing module triggering events and correspond- ing software processing module block diagrams can be generated. According to the actual situation, the number of judgment relays can be conditions can also be simplified certainty reduced in the 13 states of relays simplifying were ascertained and the judgment development of the software and reducing the uncertainty.
