Description

Abnormality diagnosis method and system, server, home appliance and environment sensor

technical field

The present invention relates to the technical field of household appliances, in particular to an abnormality diagnosis method, an abnormality diagnosis system, a server, a household appliance and an environment sensor.

Background technique

With the development of wired/wireless communication technology, users' demand for smart products is increasing day by day considering the convenience of use of products. The functions of smart products are becoming increasingly complex and diverse, and after-sales services such as fault diagnosis of smart products have become important issues.

The specific process of executing the abnormality diagnosis of the existing household appliance abnormality diagnosis system of the smart kitchen system is as follows:

(1) The control module in the "server" controls the startup of the diagnosis mode, and sends a diagnosis command to the "first diagnosis module" on the server side.

(2) The "first diagnostic module" on the server side generates command signals (used to control the built-in "second diagnostic module" in the executive appliance MCU), and sends the command signals to the "first communication module" on the server side.

(3) The "first communication module" on the server side converts the command signal sent by the "first diagnostic module" on the server side through a predefined communication protocol (for example, RS_485 communication protocol), and converts the converted command signal in a wireless or wired manner The signal is sent to the "second communication module" at the electrical appliance end.

(4) The "second communication module" on the electrical appliance side converts the command signal converted by the "first communication module" on the server side again through a pre-defined communication protocol (for example, RS_485 communication protocol), and sends the command signal converted again To the "Second Diagnosis Module" on the appliance side.

(5) The "second diagnostic module" on the electrical appliance side executes the diagnostic function, and sends the result data to the "second communication module" on the electrical appliance side.

(6) The "second communication module" on the electrical appliance side converts the above-mentioned result data through a predefined communication protocol (for example, RS_485 communication protocol), and sends it to the "first communication module" on the server side in a wireless or wired manner.

(7) The "first communication module" on the server side reconverts the result data converted by the "second communication module" on the electrical appliance side according to a predefined communication protocol (for example, RS_485 communication protocol), and sends the converted result data again To the "first diagnostic module" on the server side.

(8) The "first diagnosis module" at the server end sends the converted result data to the control module, and ends the diagnosis mode.

It can be seen that the existing diagnostic system only uses the pre-programmed diagnostic module built in the MCU to diagnose the abnormality of household appliances, so it cannot diagnose whether the functions not included in the pre-programmed diagnostic module at the initial stage of product development are abnormal. Moreover, once the diagnosis module is started, all pre-programmed codes need to be executed, so it needs to wait for a certain period of time in order to obtain the diagnosis result. In addition, the existing diagnostic module is built into the MCU. When the diagnostic algorithm needs to be updated, the after-sales service personnel need to personally visit each user’s home to update the firmware of the diagnostic program built into the MCU. In this way, manpower and capital are increased. investment and reduce customer perception.

To sum up, the existing home appliance abnormality diagnosis system of the smart kitchen system has problems such as single diagnosis basis, low accuracy, long diagnosis running time, and difficulty in updating the diagnosis algorithm.

Therefore, there is a need for a new abnormal diagnosis system for household appliances. On the one hand, it can diagnose abnormalities of household appliances more quickly and accurately, thereby providing users with more accurate maintenance information of household appliances and improving users' satisfaction with maintenance services; On the other hand, it can realize the online update of the diagnosis algorithm, reduce the maintenance cost and further improve the service quality and user experience.
