Method for automatically detecting air conditioner outdoor unit control panel

Abstract

The invention discloses a method for automatically detecting an air conditioner outdoor unit control panel, which adopts different detection modes according to different functional circuits on the outdoor unit control panel, and mainly comprises communication circuit detection, direct current fan drive circuit detection, sensor sampling circuit detection, high and low level input circuit detection, weak current drive circuit or relay circuit detection and the like. The special method for automatically detecting the air conditioner outdoor unit control panel provided by the invention not only can prevent the control panel to be detected from being damaged during the detection process, can qualitatively determining and quantitatively detecting all the functional circuits of the control panel to be detected through adopting a mode which combines manual judgment and automatic judgment, but also can detect both two states of 'on' and 'off' of a switching input, so the accuracy of the detection result is improved, and the detection efficiency is also taken into consideration.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration engineering, and in particular relates to a method for detecting an outdoor unit control panel of an air conditioner. Background technique [0002] With the gradual warming of the earth's climate and the continuous improvement of people's living standards, air-conditioning products have gradually entered thousands of households and are widely used. Existing air-conditioning products generally include two parts, an indoor unit and an outdoor unit, and no matter in the indoor unit or the outdoor unit, a control board for coordinating and controlling the execution components is provided. For the performance testing of air-conditioning products, it can be said that most of the time is tested on the indoor unit control board and outdoor unit control board of the air-conditioning product. [0003] At present, there are many detection methods proposed for the outdoor unit cont...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many detection methods proposed for the outdoor unit control board of air-conditioning products, but most of them use the detection method of external actual load, which belongs to strong current detection, and the detection results mainly rely on manual judgment, so there is a possibility of misjudgment higher

Moreover, during the testing process, if the operation is not done properly, the control board to be tested will be damaged, which will lead to more faulty machines and higher hardware costs.

In addition, since the traditional detection scheme judges the quality of the control board by observing the actual operating status of the air-conditioning product, this detection mode can only make a qualitative judgment on whether the control board is qualified or not, and cannot do quantitative Therefore, even if the control panel is qualified, it is not necessarily a qualified product, and there are doubts about the accuracy of the test results.
