鞍钢矿山公司五大露天铁矿,铁路运输是主要运输形式,其铁路信号控制设备采用传统的继电器式,该设备继电器用量大,故障率高。为提高矿山运输效率,鞍钢矿山研究所和齐大山铁矿共同研制了“PC车站联锁集中系统”,将八十年代国际水平的PC技术应用于矿山铁路信号系统。PC即可编程序控制器,是一种数字控制专用计算机,它可以记忆贮存指令,执行诸如顺序计时、计数和运算等功能,并通过各类开关量或模拟量的输入/输出模块,以控制各种自动化装置。而PC车站联锁集中是通过软件程序实现信号集中联锁的。信号设备在FC操纵下,防止了向独头线重复发车的可能性,有效地杜绝了正面撞车事故的发生。这一系统有较强
Anshan Iron and Steel Company five major open-pit iron ore, rail transport is the main form of transport, the railway signal control equipment using the traditional relay type, the device uses a large amount of relay, high failure rate. In order to improve the efficiency of mine transportation, Anshan Iron and Mining Institute and Qidashan Iron Mine co-developed the “PC Station Interlocking Centralized System” to apply the world-class PC technology of the 1980s to mine railway signaling systems. PC is a programmable controller. It is a special digital control computer that can store and store instructions, perform functions such as sequential counting, counting and computing, and control various types of digital or analog I / O modules Various automation devices. The concentration of PC station interlocking through the software program to achieve centralized signal interlocking. The signal equipment under the control of FC prevents the possibility of repeated starting to the single-headed line and effectively eliminates the occurrence of a frontal crash. This system is stronger
