采用PC机控制的矿井“信集闭”系统的数学模型

Mathematical Model of Mine Signal Centralizing and Locking System Contolled by Programmable Controller

把PC机应用于矿井“信集闭”系统在国内还是首次,为了适应PC机控制的需要,本文分析了矿井“信集闭”系统中的一些问题,建立了一种数学分析模型。该模型以布尔矩阵为基础。准确地描述了“信集闭”系统的各种联锁关系,并具有运算速度快,适应性强,联锁严密的优点。

It is the first time that a PC(Programrnable Controller )is used to control the signal centralizing and locking system of the mine in China. This paper analyses a few questions in the system and sets up a kind of mathematical model to meet the needs of PC controlling. Based on Boolean matrix this model describes all kinds of locking relationship in the system and it has the advantages of fast computing speed,strict locking and wide compatibility.
