1、 Interlocking system is a safety control system which is used to train and train traffic control in station and depot. The system includes the realization of the interlocking relationship, the establishment of access, control of the switch and the opening of the signal machine, as well as access to
2、unlock, in order to ensure traffic safety. The interlocking equipment is divided into mainline station interlocking equipment and depot interlocking equipment. Interlocking equipment in the early use of relay interlocking, and now more use of computer interlocking system. Electric interlocking Elect

6、ignal machine, switch machine, and other outdoor equipment. The software is the core part of realization route, signal and switch interlock logic, consists of two parts: one is involved in the interlocking computing station database; two is the interlocking logic operation, applications to complete
7、the interlock function. The station database includes the station assignment table, the station interlocking table, the push button access table, the station display data, etc The application is composed of a plurality of program modules, system management module, clock interrupt program management

14、nterlocking system uses the method of modifying the data, and almost no need to change the existing circuit and interlocking program to meet the need. Facilitate system maintenance. Most of the computer interlocking system is electronic equipment, these electronic devices have no mechanical wear, so
15、 the daily maintenance amount is small. In addition, the computer interlocking system often has perfect monitoring phase fault diagnosis function, which is convenient for the maintenance personnel to analyze and find and timely troubleshooting.
