Air conditioner controller automatic test equipment and test method thereof

Abstract

The invention provides an air conditioning controller automatic test device and method which employs single-chip computer technology. The device can carry out complete automatic test, even in one person-multi-testers automatic test way and can realize the generalization of testers, reducing the quantity of testers significantly. Diversified working conditions under which the air conditioner works can be obtained by simulating with voltage, thereby reducing the difficulty of the air conditioning controller test. The device comprises a tester, a thimble connected with a contact of a controller under test, a thimble mounting seat and a connecting lead connecting the thimble and an element of the tester circuit. The tester comprises a shell and elements of the tester circuit which comprises a main-board, a connecting board between the main-board and the thimble mounting seat and a light board. The main-board comprises an HV feedback signal processing circuit, a scavenging motor detecting circuit, a control signal output circuit, an infrared signal transmission circuit, a simulation temperature voltage signal generating circuit, a light board driving circuit and a single-chip microcomputer. The light board of the tester is provided with a display device.

Description

technical field [0001] The invention relates to the testing field of air-conditioning controllers, in particular to an automatic testing device and testing method for an air-conditioning controller. Background technique [0002] For mass-produced products, in order to improve production efficiency, modern production and methods use assembly lines for operations, and automatic mechanical equipment is installed in each corresponding part of the assembly line, which greatly reduces the labor intensity of workers. In the production process of air conditioners, it is necessary to test the controller. In order to improve the test efficiency of the controller, reduce labor intensity, save costs, and the test process is not affected by human factors, it has become an inevitable trend to develop automatic test equipment. Now the single-chip microcomputer technology is quite mature, making automatic testing possible. [0003] The patent number is: CN200520058176.9, and the title is: ...

AI Technical Summary

Problems solved by technology

The air conditioner test system in this patent is mainly realized by PC microcomputer and PC multi-function expansion card. The computer needs communication to control various components to detect the controller. At the same time, the detection results also need communication to feed back the results to the PC. Once the communication fails, it will cause misjudgment.
