Abstract

A network household electric control system has a household electric appliance controlling ASP server installed as an external server (300) on the Internet. When household electric appliances (150) are to be controlled from an operation terminal (130) in the house of a customer through a home server (120), the GUI is transparently transmitted from an external server to the operation terminal and is displayed with the browser so that the household electric appliances are monitored and controlled through that GUI.

Claims

1. A control system for networked home electrical appliances comprising:

an external server to receive through a global network a CGI program execution instruction from an optional terminal, execute a CGI program registered in advance, and transmit a result of the execution to the accessed terminal;

a home electrical appliance having a communication function and connected to a home network;

a home server connected to the home network, to control each home electrical appliance connected to the home network; and

an operation terminal connected to the home network and having a browser function, and

the external server is configured to have a function of returning a screen or a control code corresponding to a request from the operation terminal, and

the home server is configured to have a function of receiving a request from the external server, a function of transmitting a request to the external server, a function of relaying a request from the operation terminal to the external server behind the scenes, a communication function of controlling each home electrical appliance, and a function of receiving a notification from each home electrical appliance.

2. The control system for networked home electrical appliances as set forth in claim1, characterized in that:

the external server holds a GUI to monitor and control the home electrical appliance; and

in response to an access from the operation terminal, the home server accesses the external server behind the scenes and displays the GUI on a screen of the operation terminal as if it is on its own device.

3. The control system for networked home electrical appliances as set forth in claim 2, characterized in that:

the GUI has a relative pass of a CGI program written in an action field of a command on the home server; and

when receiving the command on the home server from the operation terminal, the GUI executes the CGI program specified by the relative pass in the action field of the command and returns a result of the execution to the operation terminal.

4. The control system for networked home electrical appliances as set forth in claim 3, characterized in that a module on the home server is executed according to the GUI supplied from the external server with use of arguments including a URL to be accessed upon a success of processing and a URL to be accessed upon an abnormal termination of processing.

5. The control system for networked home electrical appliances as set forth in any one of claims 1 to 4, characterized in that a secured protocol is used for communication between the external server and the home server and an unsecured protocol is used for communication between the home server and the operation terminal.

6. The control system for networked home electrical appliances as set forth in any one of claims 1 to 5, characterized in that full passes are described only for image files in the GUI output from the external server.

7. The control system for networked home electrical appliances as set forth in any one of claims 1 to 6, characterized in that the external server provides different service menus when accessed through the home server and when directly accessed.

8. The control system for networked home electrical appliances as set forth in any one of claims 1 to 7, characterized in that:

the operation terminal transmits data specifying its type; and

the external server refers to the data to determine the type of the operation terminal accessing the external server through the home server and provides a different service menu depending on the determined type.

9. The control system for networked home electrical appliances as set forth in any one of claims 1 to 8, characterized in that:

the operation terminal or the home server holds customer identification information and transmits the customer identification information when accessing the external server; and

the external server holds, as customer information, information about home electrical appliances of each customer, extracts corresponding customer information according to the customer identification information when providing a service menu in response to the access from the operation terminal or the home server, and enables only services providable by home electrical appliances owned by the customer in question.
