Air conditioner external unit body cleaning platform

Abstract

The invention relates to an air conditioner external unit body cleaning platform. The air conditioner external unit body cleaning platform comprises an external unit assembling structure, dust detection equipment and automatic blowing equipment, wherein the external unit assembling structure comprises a machine body, a compressor, a condenser, a capillary tube, an axial fan, an outdoor fan and anelectrical element, and the compressor, the condenser, the capillary tube, the axial fan, the outdoor fan and the electrical element are arranged in the machine body; the dust detection equipment searches corresponding dust sub-images from a debris combined image based on the dust image characteristics, recognizes a plurality of dust pixels in the dust sub-images based on a preset dust upper limitthreshold value and a preset dust lower limit threshold value, the dust pixels are fit to a dust area, the area percentage of the dust area occupying the dust sub-images is determined, and sends a dust excessive signal when the area percentage exceeds the limitation; and the automatic blowing equipment is used for starting the blowing operation of the machine body when the dust excessive signal is received. According to the air conditioner external unit body cleaning platform, automatic cleaning of an air conditioner external unit can be realized.

Description

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to a cleaning platform for the body of an air-conditioning external unit. Background technique [0002] The temperature sensor on the heat exchanger of the air conditioner's external unit is used to detect the pipe temperature of the heat exchanger during cooling. If the temperature rises abnormally, the pipe pressure can be calculated, and then the abnormal temperature signal is sent to the control board. The outdoor temperature sensor of the outdoor unit is mainly used to detect the outdoor ambient temperature. Contents of the invention [0003] In order to solve the technical problem that the external unit of the air conditioner is not easy to clean, the present invention provides a cleaning platform for the external unit of the air conditioner, which can realize the automatic cleaning operation of the external unit and reduce dangerous manual operations. Brightness m...

Problems solved by technology

[0003] In order to solve the technical problem that the external unit of the air conditioner is not easy to clean, the present invention provides a cleaning platform for the external unit of the air conditioner, which can realize the automatic cleaning operation of the external unit and reduce dangerous manual operations. Brightness mean value analysis to determine each homogenized fragment that deviates from the image-level brightness mean value and perform corresponding directional edge deepening processing, thereby reducing unnecessary operations; using various parameters of the image to correct the binarization threshold of the image at the same time, The accuracy of the obtained binarized image is guaranteed; the presence of dust particles is physically detected by using a custom-made dust measuring instrument based on the relative attenuation rate of parallel monochromatic light based on detection common sense. On this basis, the image analysis mode is used to Dust particles are confirmed, and the ultrasonic dust removal mode is used for directional removal of dust particles
