On-line upgrading control method of household appliance system and household appliance system

Abstract

The invention discloses an on-line upgrading control method and a home appliance system. The home appliance system comprises a functional component connected with an external memory. The on-line upgrading control method comprises the following steps: the server is inquired whether there is an available software update of the functional component; if so, the available software updates are downloaded to the external memory, and the original software of the functional component is backed up to the external memory; and available software updates are obtained from an external memory and updating the functional components to be updated with the available software updates when the functional components to be updated are idle or the home appliance system is restarted. As such, when a software update is available for that home appliance system, the software version is automatically downloaded and updated, and the downloaded usable software updates and the original software are stored in an external memory. On the premise of ensuring that the software upgrades can be rolled back, the modification of each piece of electronic control hardware of the household appliance system is reduced, and the master control chip with larger storage space need not be replaced, so as to reduce the type selection cost of the master control chip.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an online upgrade control method of a household appliance system and the household appliance system. Background technique [0002] At present, under the trend of Internet of Everything, home appliances can be connected to the Internet through communication modules, which has become a standard function of new home appliances on the market. Terminal equipment connected to the network, in addition to bringing personal usage habits, cloud storage and analysis services to users, terminal equipment can also automatically download and update software versions through networking. [0003] For example, as a complex home appliance system, an air conditioner can be divided into multiple independent functional modules, and each module has an independent software version number. Because of the complexity of the air conditioner system software, few air conditioners on the market support onl...

Problems solved by technology

[0003] For example, as a complex home appliance system, an air conditioner can be divided into multiple independent functional modules, and each module has an independent software version number. Due to the complexity of the air conditioner system software, few air conditioners on the market support online upgrades.

For air conditioners that support online upgrades, the main control chip of the air conditioner usually needs to use twice the storage space of the application code in order to back up the old code, which directly increases the cost of the main control chip selection
