Test platform for trackside interlock system and test method based on same

Abstract

The invention discloses a test platform for a trackside interlock system. The trackside interlock system comprises a first logical operation module and a second logical operation module. The test platform comprises a first switcher, a second switcher, a router, two dispatching systems for dispatching supervision, three working stations for man-machine interaction, a dispatching data recorder for storing event logs, a communication data recorder for recording data messages, an environment simulator computer for simulating input of trackside signals, a first simulation board and a second simulation board. The test platform can perform a simulation integration test well and has the advantages of being simple in structure, easy to built and maintain and high in reliability and expandability. The invention further discloses a test method based on the test platform. By means of the test platform and the test method, input and output of trackside equipment can be comprehensively simulated to achieve testing of various operation scenes and various fault scenes.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a test platform and a test method for a trackside interlocking system. Background technique [0002] The wayside interlocking system is the core subsystem in the rail traffic control system, which is dedicated to implement the security function of the wayside interlocking logic. It interfaces with trackside equipment through a safe interface circuit to collect and control signals, switches, axle counters, emergency stop buttons, platform screen doors and anti-flood doors, etc. With the rapid development of my country's urban rail transit, the testing of trackside interlocking software is becoming more and more common. It is necessary to effectively provide a laboratory simulation test environment and test method for the interlocking system. At present, there are mainly the following two methods: [0003] The first is to simulate all subsystems and wayside equipment except the interl...

AI Technical Summary

Problems solved by technology

[0005] The first test method is suitable for white box testing of interlocking systems, and is generally used for development and testing of interlocking system software personnel, and does not have the conditions for simulation integration testing

The second one can integrate various subsystems together for simulation testing, but there are many shortcomings, the hardware platform is more cumbersome, there are more input and output lines or boards, the hardware cost is high, maintainability and scalability Poor performance, unable to perform fault scenario test, weak practicability
