Railway signal microcomputer interlock system

Abstract

The invention relates to a railway signal microcomputer interlocking system capable for meeting the operating requirement of railway transportation of a metallurgical enterprise. The railway signal microcomputer interlocking system is characterized in that the railway signal microcomputer interlocking system is divided into six physical levels, namely a human-computer session layer, an interlocking computation layer, a double-nucleus driving layer, a combined circuit layer and a monitoring object layer so as to complete the interlocking function of various signals of a railway yard. The railway signal microcomputer interlocking system can increase transporting efficiency, improve labor condition, reduce accident rate of safety, realize modernized management of transportation and bring economic benefit so that gradual pulling of spring railroad switches by transporting personnel in the prior spot is changed into concentrated control of the railroad switches in a control chamber, thereby realizing interlocking; and the railway signal microcomputer interlocking system greatly shortens transportation time, saves comprehensive expense more than 30 percent, reduces equipment maintenance expense and reduces the workload of maintenance.

Description

technical field [0001] The present invention is a control technology based on modern control technology, communication technology and computer technology. Many locomotives, low speed, high shunting density and other characteristics of the railway signal microcomputer interlocking system can meet the requirements of metallurgical enterprises for railway transportation operation. Background technique [0002] At present, my country's railway standard 6502 railway signal control is based on the electromagnetic relay system, which has: heavy equipment, single function, large maintenance, difficult maintenance, difficult to connect with the upper management computer network, and difficult to network with other modern railway transportation control systems. It has not adapted to the needs of modern control and management of railway transportation. Contents of the invention [0003] The purpose of the present invention is to provide a system that uses microcomputer as the main te...
