Refrigerator inverter compressor life index calculation system and method

Abstract

The invention discloses a refrigerator inverter compressor life index calculation system and method, and relates to the technical field of compressor life indexes. The system comprises a refrigerator intelligent controller and a cloud system. The refrigerator intelligent controller comprises a micro-control unit, a power-on and power-off timing unit, a storage unit and a rotating speed detection unit. The micro-control unit is in electric signal connection with the power-on and power-off timing unit, the storage unit and the rotating speed detection unit. The micro-control unit controls the power-on and power-off timing unit to calculate and obtain compressor power-on time P, compressor high-speed running time Q and compressor power-off time R; the micro-control unit controls the compressor power-on time P, the compressor high-speed running time Q and the compressor power-off time R to be multiplied by a corresponding weighting factor, summing and dividing by the compressor rated life T to obtain a compressor life index Y; a user is helped to know the overall operation condition of the refrigerator; calculation is simple, and the value of data collected by the cloud is exerted.

Description

technical field [0001] The invention belongs to the technical field of compressor life index, and in particular relates to a calculation system and method for the life index of a frequency conversion compressor of a refrigerator. Background technique [0002] The biggest difference between smart home appliances and ordinary home appliances is that smart home appliances are connected to the Internet of Things, and can transmit the status information of home appliances themselves, such as refrigerator temperature and compressor operating status, to the cloud control center through the existing communication network. [0003] In the era of intelligence, the application of big data has gradually penetrated into social production and people's lives. People gradually realize the value contained in big data, and reasonable mining and analysis of big data will help product design and guide users to use products rationally. At present, smart refrigerators have been on the market for...
