A test method, test device and test system for a train air conditioning system

Abstract

The invention discloses a test method of a train air conditioning system. The test method comprises the steps of constructing a train control system TCMS simulation device and an air conditioning system simulation device and designing an air conditioning working condition strategy in advance, calling and combining configuration items in a preset air conditioning working condition strategy to generate a test case according to input test configuration parameters, and then sending the test case to the train control system TCMS simulation device, thereby enabling the train control system TCMS simulation device to execute a test on the air conditioning system simulation device according to the test case, obtaining an operation working condition feedback result of the air conditioning system simulation device and outputting the result. The human cost required to be invested in multiple tests is saved, the test requirements of different projects can be adapted, meanwhile, the test method canbe adapted to train air conditioning simulation online tests which need to be executed for a long time, and the test range of the train air conditioning before leaving a factory is widened. The invention further discloses a test device and a test system of the train air conditioning system, and the test device and the test system have the beneficial effects.

Description

technical field [0001] The invention relates to the technical field of train testing, in particular to a testing method, testing device and testing system of a train air conditioning system. Background technique [0002] The train air-conditioning system is an important part of the train operation system, and the operation test of the train air-conditioning system is also an important part of the train operation test. [0003] figure 1 It is a structural schematic diagram of a test system for a train air conditioning system in the prior art. The current test system of the train air-conditioning system consists of an air-conditioning controller 101 , a test bench 102 and an MVB analyzer 103 . Such as figure 1 As shown, the test bench 102 is connected to the air conditioner controller 101 through a hard line, and is used to simulate the switching action of the actual hardware and the input of the analog value; the MVB analyzer 103 sends hexadecimal instructions through the ...

Problems solved by technology

And due to the high degree of manual participation, the existing test system of the train air-conditioning system is an offline single-point test, which can only verify some basic functions, and cannot perform continuous long-term operation to verify the performance indicators of the air-conditioning control software to be tested, and thus cannot Simulate the actual train system operating conditions, so that some test items cannot be tested before the equipment leaves the factory, and can only rely on the actual train monotony and train adjustment of the OEM, as well as the circular railway experiment of the Academy of Railway Sciences. The cost of modifying software bugs is very high
