Air conditioner controller automatic testing system and testing method thereof

Abstract

The invention discloses an air conditioner controller automatic testing system. The air conditioner controller automatic testing system comprises an upper computer and a lower computer which are in communication, the upper computer comprises a data calculating and processing unit and a testing result display unit, and the lower computer comprises one or more of a remote control code emitting unit, a temperature wrap unit, a motor driving and measuring unit, a communication unit, a motor rotating speed measuring unit and a display testing unit. The testing system can automatically test the logic function of an air conditioner controller, the detecting process is controlled by the computers, the defects of manual testing are completely overcome, and testing efficiency is improved. In addition, through the testing system, test cases are unified, the consistency of product testing results is guaranteed, a certain function can be verified automatically and repeatedly according to needs, the test cases are designed to find problems, data are automatically recorded, high traceability is achieved, the problem relevance ratio is high, and meanwhile the method for detecting the problems can be accumulated constantly to form new test cases.

Description

technical field [0001] The invention relates to the field of air conditioner logic function test, in particular to an automatic test system and a test method for the logic function of an air conditioner controller. Background technique [0002] At present, air conditioners widely use microprocessors as controllers to execute corresponding logic functions, thereby realizing various specific functions of the air conditioner. Whether the logic function of the controller is reliable is an important item to judge whether the air conditioner can normally realize the air conditioning function. But at present, the logic function test of the controller basically depends on people, all manual, the efficiency is not high, and the technology is relatively backward. The following problems exist in the use of pure manual testing: (1) The dependence on people is relatively large, and different people have different understandings of the same logic function specification, and there may be ...

Problems solved by technology

But at present, the logic function test of the controller basically depends on people, all manual, the efficiency is not high, and the technology is relatively backward

The following problems exist in the use of pure manual testing: (1) The dependence on people is relatively large, and different people have different understandings of the same logic function specification, and there may be deviations; (2) The repeatability verification is not strong, and the same test operation is performed manually , the results may be different; (3) The coverage rate depends on repeated testing by experienced people; (4) The testing process is not conducive to monitoring, and the method of detecting problems is poor in portability, and needs to rely on checklists

This patent uses thimbles to collect the driving signals and feedback signals of the circuits of the various components of the air-conditioning controller. When testing different control boards, it is necessary to rearrange the position of the thimbles on the thimble mounting base. The pre-test preparations are time-consuming. In addition, the system Use the light board to display the test results, the test results are relatively simple, and cannot display the defect location of the logic function of the air conditioner controller and record the test data, so it is impossible to conduct a comprehensive test
