Abstract: Air conditioning products combine all kinds of intelligent control technology and operation information collection technology, and have strong self-troubleshooting ability. With the popularization of Wi-Fi function in air conditioning products, the remote after-sales service of air conditioning products is gradually realized. The air-conditioning products collect operation information, and then communicate with the website server through Wi-Fi module, so as to realize the remote after-sales service of air-conditioning products. Compared with the traditional air-conditioning maintenance methods, they have greatly improved the maintenance efficiency. The use of the system simplifies the air conditioning after-sales service process, improves the product maintenance efficiency, and is conducive to promoting the improvement of the quality of air conditioning products.

Key words: Telediagnosis, After-sales of air conditioner, BDA, Fault analysis
