Home appliance fault diagnosis method and system

Abstract

The invention discloses a home appliance fault diagnosis method and system, which receives the fault information sent by the home appliance based on the Sigfox network and judges whether it is valid; if not, sends a scan command to the home appliance, so that the home appliance scans its own sensor based on the scan command to obtain secondary fault information , the home appliance fault diagnosis platform receives the secondary fault information, and diagnoses the fault of the home appliance based on the secondary fault information. By judging whether the fault information is valid, when the fault information cannot specifically reflect the cause of the fault, send a scan command to the home appliance, so that the home appliance starts the sensor to scan to obtain the scan data, and sends the secondary fault information containing the scan data to the home appliance fault diagnosis platform , so that enterprises can know the cause of home appliance failure, improve the accuracy of home appliance failure diagnosis, and carry out targeted after-sales maintenance, thereby improving the efficiency of home appliance maintenance.

Description

technical field [0001] The invention belongs to the technical field of network home appliances, and in particular relates to a home appliance fault diagnosis method and system. Background technique [0002] After home appliances are sold to customers, whether their fault diagnosis and after-sales maintenance are in place is also an important indicator for improving product quality. [0003] When an existing home appliance fails, it usually reminds the user by alarming or displaying a fault code, and the user contacts the after-sales service center for maintenance; or, the information such as the fault condition and the fault code is sent to the after-sales maintenance of the home appliance through the network. On the platform, the home appliance after-sales maintenance platform actively initiates after-sales maintenance. [0004] However, the existing fault diagnosis and maintenance methods have the following problems: the above-mentioned fault reporting method requires the...

Problems solved by technology

[0004] However, the existing fault diagnosis and maintenance methods have the following problems: the above-mentioned fault reporting method requires the customer to call the after-sales maintenance center of the fault code displayed on the home appliance, and the maintenance personnel will roughly analyze the possible problems according to the fault code and then go to the Repair at the user's home, which makes the maintenance process cumbersome and time-consuming; or send the fault code to the after-sales maintenance center through the Internet, and the maintenance personnel analyze the possible problems according to the fault code and then go to the user's home for repair, but this method relies on WIFI The operation of high-power network devices and network transmission, and the abnormal operation of any regional network will affect the stability and reliability of the home appliance after-sales maintenance network, resulting in the failure code of home appliances cannot be accurately reported to the after-sales service center, reducing the after-sales service. The effect of maintenance
