An automatic and fast online test method and test module for adhesion control program

Abstract

The invention discloses an adhesive control program's automatic and rapid online testing method and testing module wherein the testing method comprises 1) setting a testing module to control a testing process for a to-be-tested adhesion control program; 2) in a testing mode, allowing the tested adhesion control program to execute testing procedures according to designated testing tasks by using the testing module and during the testing, simulating the running environment for the tested adhesive control program through the testing module; transferring the output signal of the tested adhesion control program to a pre-established adhesion control object model in order to simulate the running states of a vehicle and wheels thereof; and generating required information to the tested adhesion control program. The testing module includes a testing control logic unit and the following two elements in connection with the testing control logic unit: an adhesion control object model unit and a testing environment simulating unit. The testing method and testing module of the invention can be conveniently operated to achieve higher testing efficiency and precision at a lower testing cost. The method and module are also capable of conveniently repeating fault conditions. The testing process is also a safe and reliable one.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an automatic fast on-line testing method and a testing module for an adhesion control program suitable for rail transit vehicles. Background technique [0002] Such as figure 1 As shown, the rail vehicle adhesion control program runs by receiving input signals from the outside world, including driver handle commands, commands issued by the vehicle control system (including network control systems, air brake control systems, etc.), torque command signals, and current wheels. For the motion state, the current vehicle motion state, the current motor state, and the current inverter current module working state, after comprehensively considering various factors in the adhesion control program, the adhesion control command is output to the inverter module, and the inverter module then Control the motor to pull the vehicle forward and backward. [0003] For the test of the sticki...

Problems solved by technology

However, building a complete set of semi-physical simulation test platform is still not a simple matter. It usually requires huge hardware resources and consumes a lot of man-hours, manpower and material resources; There are great difficulties in the physical simulation test system, which is difficult to implement in practice

In addition, the semi-physical simulation test system usually needs to be equipped with a real-time simulation platform for model calculation, a host computer for test management and model management configuration, a chassis for actual testing, various connection boards and networks, etc. Large and inconvenient to carry, so it is difficult to meet the testing needs of solving sudden problems on site

Therefore, the test of the adhesion control program is not suitable for direct use of the built semi-physical simulation test system.
