A general automatic test system for rail transit signal equipment

Abstract

The invention discloses a general automatic test system for rail traffic signal equipment, which has flexible interface and protocol configuration, automatic test, and has the functions of modeling of tested equipment and project management. Its technical solution is: use keyword-driven, scalable, and easy-to-write test sequences as the test script editing method, support the transmission mode of the communication interface required by rail transit signal equipment, and interconnect with the test excitation source through Ethernet to avoid communication with The coupling between test stimulus sources can be added and configured according to the actual test interface needs, so as to facilitate the configuration and semantic definition and mapping of communication protocols. Realization includes system requirements, test requirements, requirements change management, test case management, test script framework import and generation, test script editing, test plan generation, test plan execution, test process recording, test report generation, automatic generation of round test plans according to defects And other closed-loop test management, which improves 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...
