Embodiment Construction

[0041] The present invention will be further explained below in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown, a kind of heat pump type electric vehicle air conditioner defrosting control system based on computer vision technology of the present invention comprises low-pressure heat exchanger 1, general controller 2, computer vision system 7; Wherein,

[0043] The low pressure sensor 1 is connected with the master controller 2, and is used to monitor the low pressure of the air conditioning system in real time, save the low pressure value in a low pressure storage period, and feed back the low pressure value to the master controller 2.

[0044] The main controller 2 is used to make logical judgments of entering and exiting the defrosting control; according to the low pressure value fed back by the low pressure sensor 1, judge whether to turn on the computer vision system, take pictures of the evaporator, analyze the frosting degree of the evapo...

Abstract

The invention discloses a heat pump type electric vehicle air conditioner defrosting control system and method based on computer vision technology. The system includes a low-pressure heat transfer device, a general controller, and a computer vision system; a low-pressure sensor detects a low-voltage value and feeds back to the general controller , the main controller judges whether to turn on the computer vision system according to the low pressure value; the camera transmits the captured evaporator picture to the image storage system for storage, and the image recognition and analysis system analyzes and recognizes the image, and calculates the frosting rate of the evaporator. When the frosting rate of the controller reaches 50%, the main controller sends out a defrosting command, and the air conditioning system enters the defrosting logic. defrost. The invention adopts computer vision technology to intelligently judge the frosting degree of the evaporator, overcomes the defects of the traditional defrosting method, can accurately judge the frosting situation of the evaporator, and make a correct defrosting action.

Description

technical field [0001] The invention relates to a defrosting control method for an air conditioner of a heat pump electric vehicle, in particular to a defrosting control system and method for an air conditioner of a heat pump electric vehicle based on computer vision technology. Background technique [0002] The existing traditional defrosting control methods for heat pump air conditioners generally include several types as shown in Table 1 below: [0003] Table 1 [0004] [0005] The above traditional defrosting control methods all have certain defects. The defrosting judgment is not accurate, and misoperations such as "no defrosting with frost" or "no frost defrosting" will occur. Contents of the invention [0006] The purpose of the present invention is to provide a heat pump electric vehicle air conditioner defrosting control system and method based on computer vision technology, aiming to solve the defrosting detection and defrosting control problems of the heat ...
