Problems solved by technology

[0003] At present, there are many detection methods proposed for the indoor unit control board of air-conditioning products, but most of them adopt the detection method of external load, which belongs to strong current detection, and the detection results mainly rely on manual judgment, so the probability of misjudgment is relatively low. high
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 f

Embodiment 1

[0040] Embodiment 1, in order to make the proposed indoor unit control board detection strategy have a wider scope of application, that is, it can meet various types of air-conditioning products (such as commercial air conditioners, wall-mounted air conditioners, and vertical cabinets, etc.) According to the detection requirements, the functional circuits involved in the indoor unit control boards of various types of air conditioners are fully considered, and different detection methods are proposed for different functional circuits.

[0041] Specifically, the generalized design has the following detection methods:

[0042] (1) Detection of communication circuits:

[0043] For the communication circuit on the indoor unit control board, this embodiment adopts the method of formulating a communication protocol in advance, using the indoor unit control board to perform two-way communication with external communication devices, and then judging the communication according to wheth...

Abstract

The invention discloses an automatic detection method for a control panel of an air-conditioning indoor unit, and achieves the purposes that different measures are adopted to detect different functional circuits on the control panel of the indoor unit. The automatic detection method comprises the following steps: detecting a communication circuit; detecting a motor type drive circuit; detecting a sensor sampling circuit; detecting a high-low-level input type circuit; and detecting a weak current type drive circuit or a relay type circuit. By adopting the automatic detection method, damage to a to-be-detected control panel is avoided in the detecting process, qualitative detection and quantitative test of all functional circuits of the to-be-detected control panel can be achieved through both manual judgment and automatic decision, and on and off states for switching input can be both detected, so that not only is the accuracy of detection results improved and the detection efficiency is drawn 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 indoor 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 indoor unit contro...
