the intelligent home equipment is communicated with the client and the firmware upgrading server through the WIFI module, and the WIFI module of the intelligent home equipment can download and cache a plurality of firmware versions of the MCU of the intelligent home equipment from the firmware upgrading server according to the notification of the client;
the client judges whether the MCU firmware version number cached by the current WIFI module of the intelligent household equipment has the MCU firmware version number disclosed by the firmware upgrading server or not by accessing the firmware upgrading server, and if not, the client informs the WIFI module to download the corresponding MCU firmware version;
when the MCU of the intelligent household equipment needs to carry out version change, wherein the version change comprises version upgrading and version rollback, the client sends the version number to be changed to the WIFI module of the intelligent household equipment, and the WIFI module of the intelligent household equipment sends the corresponding firmware version to the MCU of the intelligent household equipment according to the received version number.
Specifically, the client may be a mobile phone APP or a webpage.
Specifically, in intelligent household equipment, accessible serial ports, communication modes such as I2C communicate between WIFI module and the MCU.
The invention has the beneficial effects that: due to the fact that the network bandwidth of WIFI connection is large, the flash space of the WIFI module is extensible, the downloading time of the firmware of the MCU can be finished within a few seconds, and the firmware of multiple versions can be cached, the method and the system can rapidly conduct upgrading operation on single intelligent household equipment or a batch of intelligent household equipment at the same time, and greatly improve the MCU firmware iteration efficiency of products and the fault tolerance rate of the equipment. And the WIFI module supports caching of multiple versions of firmware, so that the invention can also realize the version rollback function, meet the diversified version requirements of users and improve the user experience
