Embodiment Construction

[0024] Preferred embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. figure 2 It is a structural diagram of the remote control system of the household appliance according to the present invention.

[0025] Outside the home, in order to remotely control home appliances connected to the local network, the operator needs to connect to the Internet for data transmission. The remote server 100 is used to store these data, so that the operator can confirm the webpage driven by the remote server 100 outside the home.

[0026] The operator connects to the above-mentioned web page by using an Internet connection device RC such as a computer, a notebook computer (notebook), a PDA, or a mobile phone, and can remotely input control commands to household appliances in the home and check status information of the above-mentioned household appliances. In order to manage multiple local networks, the remote server 100 ...

Abstract

Data synchronization between local server and remote server can be implemented through the invention. The local server manages household electric appliances connected on local area network. The remote server through Internet controls the said household electric appliances. When communication fault occurs between remote server and local server, the local server saves updated data caused by state change of household electric appliance onto database, and sends the updated data to remote server repeatedly till the remote server receives the data successfully so as to realize data synchronization. Thus, operator no matter inside or outside home can manages identical data so as to prevent data confusion. The invention prevents data loss caused by communication fault, and raises practicability and stability of control.

Description

field of invention [0001] The present invention relates to a remote control system of home appliances, in particular to a remote control system capable of remotely controlling the home appliances connected to the local network with a local server connected to the local network. A remote control system for household appliances that realizes mutual data synchronization between servers. Background technique [0002] Refer below figure 1 The configuration of a remote control system for general home appliances will be described. [0003] In recent years, a remote control system for connecting a plurality of home appliances C1 to C4 to a local network N constructed in a home or a building and controlling the above home appliances has become more and more widely used. At present, some systems have been developed, which can use the terminal RC connected to the Internet I to remotely control household appliances outside the home or building, and expand the control field of the hous...
