Problems solved by technology

This test method can test the TCU software, but because the TCU operating environment is complex and changeable, and there are many peripheral signals, it is difficult to ensure the full coverage of the test scenarios during the test process, and the authenticity of the simulation data output by the real-time simulator is not high. High, it is impossible to realize the actual operation of the module rail transit vehicle

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0037] Such as figure 1 As shown, a kind of software test scene construction method that the present embodiment is used for rail transit comprises the following steps: S1. The test system obtains the running data of the traction drive control unit of the rail transit vehicle, and deletes the fault scene data table and the normal scene data Duplicate data in the table; S2. Classify the operating data, eliminate duplicate data, and generate software test scenarios.

[0038] In this embodiment, the specific steps of step S1 include: receiving the operating data generated during the operation of the rail transit vehicle through the data receiving device installed on the rail transit vehicle and connected to the network of each traction drive control unit, and loadin...

Abstract

The invention discloses a railway traffic software testing scene construction method which includes the steps of a test system obtaining operation data of a traction transmission control unit of a rail transit vehicle, classifying operation data, removing repetition data, and generating a software testing scene. A data repeater comprises a first network unit, a data processing unit and a second network unit, which are connected sequentially. The invention further discloses a software test simulation system including a simulation test module, a simulation database and the data repeater. The simulation data are high in reality, and can simulate and restore the real operation situation of a rail transit vehicle, and full coverage of a test scene in a software testing process is effectively ensured. The data repeater has the advantages of simple structure and easy installation.

Description

technical field [0001] The invention relates to the field of simulation testing of rail transit vehicles, in particular to a method for constructing a software test scene for a traction drive control unit of a rail transit vehicle, a data transfer device and a system. Background technique [0002] The traction control unit (Tractive Control Unit, TCU) of rail transit vehicles is the core component of the traction system, which realizes the control functions of vehicle traction acceleration and regenerative electric braking deceleration, and is the "heart" of rail transit vehicles. Rail transit vehicle traction drive control unit software generally consists of inverter control software, four-quadrant control software, auxiliary variable control software, adhesion control software, bottom layer software, middle layer software, and logic control software. [0003] Existing TCU software testing is carried out on the laboratory simulation test platform, the real-time simulator ou...
