Abstract

The invention discloses a train communication network conformance test method and a device. The method comprises the following steps: (1) classifying train communication network equipment, and analyzing the conformance test requirements of the communication network of the train communication network equipment after classification to obtain an initial test requirement set of conformance; (2) optimizing the initial test requirement set to obtain a reduced test requirement set; (3) designing an initial test case set according to the reduced test requirement set, and optimizing the initial test case set to obtain an optimal test case set; and (4) testing the conformance of the communication network by use of the optimal test case set. According to the invention, the test case set is optimized on the premise of ensuring the reliability, a given test goal can be fully met with as fewer test cases as possible through test case set optimization, and therefore, the test efficiency is improved, and the test cost is reduced.

Description

technical field [0001] The invention relates to the field of train communication network consistency testing, in particular to a train communication network consistency testing method and device based on particle swarm optimization algorithm. Background technique [0002] As a popular means of transportation, railway is an important national infrastructure and national economic artery, and plays an irreplaceable role in national defense construction. In recent years, the state has increased investment in railway transportation. The investment in railway fixed assets in the "Twelfth Five-Year Plan" is 2.8 trillion yuan, of which 2.3 trillion yuan is invested in infrastructure, and 500 billion yuan is invested in equipment and renovation. 2015 is the final year of the "Twelfth Five-Year Plan" for railways. According to the plan, by 2015, the operating mileage of national railways will reach 120,000 kilometers. This year, my country's high-speed railway business mileage will ...
