Electric control board program upgrading method and device

Abstract

The embodiment of the invention provides an electric control board program upgrading method and device, belonging to the field of intelligent home appliance design. The method comprises the followingsteps of receiving an update function package from an upgrading server via a network, wherein, the identification of the update function package is different from the identification of the original function package corresponding to the electronic control panel program; using the received update function package to replace a corresponding original function package in an electronic control panel program, wherein the electronic control panel program includes a plurality of original function packages. According to the technical proposal, when the electronic control board program is upgraded, onlythe update function package is received from the upgrade server, and the received update function package is used to replace the corresponding original function package in the electronic control boardprogram, so as to reduce the access and download flow of the server, save the upgrade time, and reduce the error rate in the upgrade process.

Description

technical field [0001] The invention relates to the field of smart home appliance design, in particular to a method and device for upgrading an electric control board program. Background technique [0002] Home appliances are controlled and operated by the electric control board through the program. Program upgrades may be required in the following situations during the use of home appliances: some unknown bugs (defects) in the program, new functions need to be added to the electric control board, program version updates, etc. [0003] The existing technology provides a method for upgrading the program of the electric control board. The upgrade module downloads the upgrade package of the entire electric control board of the home appliance from the server according to the upgrade request of the electric control board. The previous program in the electric control board is written into the new software program. [0004] In the process of implementing the present invention, th...
