Abstract

The invention relates to the field of refrigerator detection, and provides a temperature detection method for compressor circulation pipelines in order to solve the problem that current refrigerator compressor pipeline detection is high in cost and low in detection efficiency. The method mainly comprises the steps of training a model image of a compressor offline to obtain a matching model of the compressor, acquiring an infrared image and temperature data flow of the compressor, locating an exhaust pipe and a local return pipe of the compressor to obtain the number of pixels and the position coordinates of the exhaust pipe and the return pipe of the compressor, and acquiring the temperature data corresponding to the position coordinates in the temperature data flow. By adopting the technical scheme provided by the invention, non-contact automatic detection of compressor pipeline temperature is realized, manpower and maintenance cost are saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of refrigerator detection, in particular to a temperature detection method of a compressor circulation pipeline. Background technique [0002] Before the refrigerator leaves the factory, a functional test is required to make a comprehensive judgment on the function of the refrigerator by integrating factors such as the internal temperature of the refrigerator, the power of the compressor, and the temperature of the compressor inlet pipe and return air pipe. At present, temperature probes are generally used to collect the temperature of the compressor pipeline. In the process of testing, winding wires and voltage instability often occur, resulting in damage to the temperature probe. At the same time, in the test line, each test station is It needs to be equipped with a special data acquisition box, which makes the test cost of this method high and the detection efficiency low.
