Test system and method of control function of visual train operation monitoring device

Abstract

The invention discloses a test system and method of a control function of a visual train operation monitoring device. Simulation test operation scenes such as a line and a train are combined with a semi-physical signal simulation device, a finished control function test environment of the train operation monitoring device is formed, an automated test and a manual intervention test which are based on the scenes are achieved and are convenient to construct, and therefore a test process is more visual and efficient. According to the technical scheme, the test method of the control function of the visual train operation monitoring device comprises the steps that human-computer interface testing, ground line and device data loading, virtual train kinematical modeling, train running position operation, train simulation running scene graphical display, controlling and collecting of a test excitation signal generator, spot responder messaging, tested device feedback information displaying and network communication are achieved by a test main control subsystem; operation information collection, operation information frame content displaying and analysis, operation state information network communication forwarding of a monitored device CAN bus under test are achieved by a device state monitoring subsystem.

Description

technical field [0001] The invention relates to a testing technology for the control function of a train operation monitoring device, in particular to a visualized system and method for testing the control function of a train operation monitoring device which combines a simulated test operation scene and a semi-physical signal simulation device. Background technique [0002] During the function test and verification process of the LKJ2000 train operation monitoring device, it is necessary to send excitation signals such as speed, pressure, working condition, track signal, and communication to it, and observe and detect its output instructions and feedback information to judge the monitoring device under test. Functional integrity, and evaluate its safety control performance. [0003] At present, in the functional test and experiment of the monitoring device, the laboratory functional verification of the monitoring device only relies on a simple simulation test device, mainly...

AI Technical Summary

Problems solved by technology

[0006] 1. Only a single test stimulus such as track signal, speed pulse signal, wind cylinder pressure and voltage signal, and working condition digital signal is given according to the operating environment required by the monitoring device, which cannot be combined with the test scene and test parameters to provide a complete functional test environment. ;

[0007] 2. Mainly send one-way test incentives to the monitoring device under test, lack of correctness judgment on the test response output by the monitoring device under test, and can only realize the open-loop test function;

[0008] 3. When the testers use the analog test device for functional testing, they need to perform cumbersome manual button operations. The test process and results need to be manually observed and recorded. The test experience is not good and the workload is heavy.
