Universal automatic test system for rail transit signaling equipment

Abstract

The invention discloses a universal automatic test system for rail transit signaling equipment, which has flexible interface and protocol configuration, automatic test and functions of equipment modeling and project management. The technical scheme is as follows: using keyword-based drivers, extensible, Easy-to-write test sequences are used as a way to edit test scripts, as the communication interface transmission mode require for supporting the signal equipment of the rail transit is interconnected with the test excitation source through the Ethernet, the coupling between the test excitationsource and the t excitation source is avoided, and the test interface mode can be added and configured according to the actual test interface requirement, so that the configuration of the communication protocol and the semantic definition and mapping are conveniently realized. Realize the closed-loop test management including system requirements, test requirements, requirements change management,test case management, test script framework import generation, test script editing, test plan generation, test plan execution, test process record, test report generation, automatic generation of round test plan according to defects, and so on, improve the degree of automation.

Description

technical field [0001] The invention relates to a simulation test system, in particular to a general automatic test system for rail transit signal equipment. Background technique [0002] For the functional integrity of a single subsystem of a rail transit signaling system or a complete large system, corresponding testing techniques are required. The current test technology mostly uses structured programming language, general scripting language, etc. to realize the automated test of the device under test. This test method requires high software programming ability of test executives, and involves a lot of test stimulus source interface encapsulation and definition work , the interface and communication protocol changes will involve a large number of underlying package code modifications, and the test script support structure has poor versatility and scalability. In addition, this test technology only realizes the automated test process of signal systems and equipment, and c...
