Abstract

The invention discloses an air conditioner fault detection method and a detection device. The detection method includes receiving external operating parameters of the air conditioner; collecting various operating parameters of the air conditioner; removing abnormal data points in each operating parameter; Calculate the change rate of each operating parameter; calculate the operation prediction value of each operating parameter according to the received operating parameters; establish a random forest model; the random forest model judges whether there is a fault condition and outputs a specific fault type. The present invention receives the external operating parameters and collects the operating parameters of the air conditioner, uses the operating parameters and operating parameters as the basis, calculates the change rate of the operating parameters and the operating prediction value, inputs the above data into the random forest model, and uses the random forest model to output The possible specific fault conditions of the air-conditioning equipment at the current moment, with high detection accuracy and strong real-time performance.

Description

technical field [0001] The invention relates to the technical field of air conditioner detection, and more specifically relates to an air conditioner fault detection method and detection device. Background technique [0002] Along with improving day by day of current people's quality of life, every household is all equipped with several air conditioners. With the continuous development of intelligent control technology, existing air-conditioning equipment is generally equipped with many intelligent control operation functions, such as voice control, voice parameter alarm, remote control, temperature, wind speed, compressor frequency intelligent control and other functions. [0003] Although the existing air-conditioning equipment is equipped with various intelligent control functions, few air-conditioning equipment is equipped with intelligent fault detection. For large-scale equipment, various abnormal conditions will inevitably appear in various modules inside the air-con...
