A Study on Development of Interlocking Inspector for Electronic Interlocking System

전자연동장치 연동검사시스템 개발

The purpose of interlocking system was to prevent the route for a train being set up and its protecting signal cleared if there was already another, conflicting route set up and the protecting signal for that route cleared. Recently, the computer based control systems instead of conventional relays circuitry are widely used to industrial systems, therefore, interlocking system are rapidly changing from relay interlocking system to Electronic Interlocking System(EIS) that control requirements of interlocking at junctions using electronic circuits. In this paper, by examine checking technique of EIS, we will to acquire interlocking inspection algorithm and method for EIS and to develope inspection system for EIS. By using inspection system we obtain every advantage. It has the functions for test data generation and automatic test execution, and it can operate on personal computer. Time and cost for test work can be reduced to more of those now required by using this developed inspection system.
