Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] The CBTC system automated test architecture includes three modules: the test engine, the tested CBTC software signal system, and the trackside simulator that provides external condition simulation, such as figure 2 shown. Among them, the test engine includes an interface to interact with the simulation module to obtain or command the state of the trackside components. The key subsystems of the tested CBTC software signaling system include mobile control unit (MCU), wayside equipment control unit (ECU) and vehicle control unit (VCU), which contains the complete software of the three control units. The wayside simulator includes a simulated wayside element (Simulate wayside element) that receives control commands from the wayside control unit to the wayside components and sends the state of the wayside components to the wayside component control unit.

Abstract

The invention discloses a simulation method of a trackside simulator for automated testing of a CBTC system. The simulation method comprises the steps of reading trackside equipment data in a data table through a compiled Python script; reading IO of each trackside device in the data table through a compiled Python script, and establishing an IO structure; organizing trackside equipment data and IO structures thereof according to different equipment types, and establishing an equipment type-data structure-IO structure mapping relationship; and reading and setting the trackside equipment stateaccording to the equipment type-data structure-IO structure mapping relationship. Accordingly, efficiency and reliability are improved.

Description

technical field [0001] The invention relates to the field of CBTC (communication-based automatic train control system) system automation testing, in particular to a simulation method of a trackside simulator for CBTC system automation testing. Background technique [0002] At present, the CBTC system still relies on manual testing to verify the function of the trackside subsystem, but for complex stations, there are many types and quantities of input and output (IO). For example, there may be hundreds of basic routes, and the verification of lateral turnouts or conflicting routes will be dozens of times or more than the basic routes. It is very inconvenient and disadvantageous to manually test the data repeatedly. Therefore, it is necessary to study automated testing, and the effective simulation design of the trackside simulator, one of the keys of automated testing, is very important. Contents of the invention [0003] The purpose of the present invention is to provide...
