CTCS-3 level train control system integrated test method

Abstract

The invention disclsoes a CTCS-3 level train control system integrated test method. According to the method, starting from key and necessity test items of an integration test, the integration test time and a driving route are combined, and CTCT-3 level train control system integration test is arranged as a whole.The method is composed of five steps, including a C2 level 90km / h pull-on test; a C3 level 90km / h pull-on test; a mobile authorization test; C3 level inter-level switching and a station track shunting test; and a manual route canceling and station side area speed limiting function test; the overall function of a C3-level system can be verified in a short time, functions of C3-level subsystems and the interface configuration function between the C3-level subsystems can be verified, the communication quality of train-ground communication can be verified, and a basis is provided for smooth joint debugging and joint testing of a signal system; meanwhile, each step is clear in thought, simple and clear in content, easy to understand and high in operability. The method is advantaged in that the universal sample plate for the C3-level integration test is provided, a solid foundation is laid for smooth development of subsequent joint debugging and joint test, a test method is provided for the integration test of the C3-level high-speed railway, and the high-quality effect of the integration test is guaranteed.

Description

technical field [0001] The invention relates to an integrated test method for China Train Operation Control System-Level 3 (CTCS-3) train control system of a high-speed railway with a speed of 250Km / h and above, which is used for signal train control before joint debugging and joint testing of CTCS-3 signal subsystems. System integration testing. Background technique [0002] First, a brief introduction to the CTCS-3 train control system. CTCS-3 train control system consists of Radio Blocking Center (RBC), Temporary Speed ​​Restriction Server (TSRS), Train Control Center (TCC), Computer Interlocking (IXL), Dispatch Command System (CTC), zpw2000 track circuit, transponder Composition; CTCS-3 level system is based on GSM-R wireless communication to realize two-way transmission of vehicle-ground information, Radio Blocking Center (RBC) generates traffic permit, track circuit realizes train occupancy check, transponder realizes train positioning, and has CTCS-2 High-level func...

Problems solved by technology

However, this method of artificially checking the difference between the expected result and the actual result causes defects such as long test cycle, low efficiency, and a large amount of waste of human resources.

Although the invention patent with the notification number CN102354209B realizes the automatic comparison process between the expected result and the actual result, saves a lot of human resources, shortens the test cycle, and improves work efficiency, it is still a simulation test system after all. Compared with the actual test, there is still a real gap in its accuracy and reliability
