Application Of Interlocking System Based On Interlocking Chart

In urban rail traffic signal control system, the computer interlocking system is an important part of core, as a part of the system to ensure the safety, a subsystem, it must be under the rules of certain interlocking trackside equipment, is a function can automatically generate interlock logic, improve the efficiency of the generated logic, reduce unnecessary human error. In this paper the system structure and function of interlocking subsystem, subsystem and the interface of the software and hardware are studied, and further studies the formulation of rules and interlocking interlocking table table application in engineering. According to system engineering theory to carry on the design, reasonable planning of rail transit signal system the function of each subsystem, realize the function module, information sharing, greatly improve the performance of the interlocking subsystem.1, the research of interlocking subsystem software design,2, research interlocking subsystem and external interface relationship between each subsystem;3, design a set of yard figure analysis module;4, arrangement plan of the main research the signal naming rules, and compiled a set of main signal arrangement;5, the interlocking table naming rules, and compiled a set of interlocking chart;6, according to the main signal layout and interlocking table, the study of interlocking logic, and the interlocking logic research7, arrangement plan of the main set up a platform and based on the signal and interlocking table provides the logic of the relationship between testing and simulation, validation logic relations correctly.
