Description

Method for Controlling Electrical Appliances of Home Network System

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home network system, and more particularly, to a product control method of a home network system in which home appliances in a home network system can be controlled in groups according to an installation location or a product type for the same command. will be.

In general, a home network system (Hmoe Network System) is a home server, that is, a home automation control system built to centrally control various home appliances centering on home appliances corresponding to a main master. In addition, the user controls the operation of other home appliances, that is, a refrigerator, an air conditioner, a washing machine, a microwave oven, a boiler, etc. through a home appliance corresponding to the master.

In addition, when a control command is transmitted from the outside through a PC or a portable terminal, the home appliance corresponding to the home server receives the control command and controls the home appliance.

In the early stages of home automation, which automatically controlled home appliances at home or remotely, each device was controlled by telephone or infrared, and there was no connection between the devices. The home network system which establishes a network between home appliances using a communication means, and has a controller which controls this network, is integrated, and is approaching the commercialization stage.

Looking at the schematic configuration of such a home network system, as shown in Figure 1, a plurality of home appliances (device 1, device 2, ..., device N) (1a ~ 1n), that is, refrigerator, air conditioner, electronic A range network, a washing machine, a personal computer (PC), and the like are connected via a communication bus or a power line to form a home network.

At this time, a plurality of each electronic product microcomputer has a serial communication function can be directly connected to the communication bus or a separate communication module for each electronic product can be used to configure the home network by using a power line as a communication line.

In addition, a controller, that is, a home server 2 can be designated to control a plurality of home appliances 1a to 1n of the home network configured as described above. Since most homes have a personal computer, a separate controller is not provided. Instead of installing the application program for controlling the network in the personal computer, all home appliances 1a to 1n connected to the network can be controlled through the home server 2.

As described above, the product control method of the configured home network system, as shown in Fig. 2, the home server 2 giving a command transmits a command data packet as shown in Table 1 below.

STX Recipient address Sender address data

At this time, the command data packet is a 1 byte STX (Start of Text) indicating the start of the message to send the contents of the data to the other party, the home server (2) itself giving the command (sender address), the corresponding household appliances that receive the command Product 1a to 1n, that is, the address of the receiver.

Here, the address of the sender and the address of the receiver are configured by 2 bytes, and the receiver address is data indicating the type of home appliances (1a to 1n) and, if two or more identical products exist, a corresponding logical address. ) And data.

When the command data packet is received from the home server 2, each of the home appliances 1a to 1n compares the recipient address of the received command data packet with its own address (S1).

As a result of the determination (S1), if the recipient address of the command data packet is the same as its own address, a command corresponding to the transmitted data is processed (S2), whereas if the recipient address is not the same as its own address, the transmitted data is Ignore it (S3).

Therefore, when the home server 2 makes and transmits the command data as the above packet, the receiving side (home appliance) receives the command data packet and compares the receiver address in the packet with its own address to perform the corresponding command. .

In the above-described conventional method of controlling a home network system, a home appliance system has a structure for giving a command to individual products, so that one home appliance is controlled for a single command. Therefore, it is impossible to control a plurality of home appliances for the same command.

In other words, if you want to turn off all of the home appliances located in a particular place because the same command must be issued several times for each home appliance, there was a problem that a lot of traffic (Traffic) occurs in the network system.

Accordingly, the present invention has been made to solve the above-described problems of the prior art, the object of the present invention is to control a plurality of home appliances for the same command in a single command using a group address to a plurality of home appliances It is to provide a product control method of a home network system to control the system.

The product control method of the home network system according to the present invention for achieving the above object is provided with a home server for transmitting the command data, and a communication function capable of communicating with the home server according to the command data received from the home server A method for controlling a product of a home network system, comprising: a plurality of home appliances, comprising: determining whether a recipient address of received command data is an individual address or a group address when command data is received from the home server; If the address of the receiver is an individual address, the home appliance having the same address as the address of the receiver, performing a corresponding command; If the recipient address is a group address, the method may include performing one or more home appliances corresponding to the group address according to a group address according to a product type or a group address according to a location.

In this case, the group address is formed by grouping addresses into all home appliances of all locations, one or more of the same home appliances of all locations, all home appliances of a specific location, one or more of the same home appliances of a specific location, etc. There is a characteristic.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

Hereinafter, a product control method of a home network system according to the present invention will be described with reference to the accompanying drawings.

3 is a flowchart illustrating a product control method of a home network system according to the present invention.

First, the home network system of the present invention is the same as the conventional system configuration, and therefore displays the same city reference numerals for the same configuration, but the present invention transmits the command data transmitted from the home server 2 to the plurality of home appliances 1a to 1n. Grouping the addresses according to the product type and location using the recipient address of is different from the above-described prior art.

In detail, the command data packet transmitted from the home server 2 includes an STX (Start of Text), an address (sender address) of the home server 2 giving the command, and a corresponding home appliance 1a to receive the command. 1n), that is, the address of the receiver.

In this case, the address of the receiver is composed of a flag (0) indicating an individual address in the case of an individual address and data representing a product type and a logical address (Logical Address) as shown in Table 2 below. As shown in Table 3, it is composed of a flag 1 indicating a group address, data indicating a product type, and data indicating a location code.

0 Product type Logical address

One Product type Location code

Here, in the case of the group address, the logical address is meaningless because one or more corresponding products assigned to the group must respond.

And, the grouping of the group address (Grouping) is set to each address according to the product type and location as shown in Table 4, all appliances in all locations, one or more of the same appliances in all locations, all appliances in a particular location Allows you to group recipients' addresses by product type or location, such as a product, one or more identical appliances at a specific location, and so on.

For example, televisions in all locations are 02FF, air conditioners in living rooms are FE02, all products in all locations are FFFF,… Group by configuring the recipient address with the grouped address.

That is, in the case of the group address, if all the data representing the product type in the recipient address is 1, all the products respond to the command, and if all the data representing the location code is 1, the products in all the locations will respond to the command. do.

In the home network system according to the present invention, a method of controlling home appliances according to the grouped addresses as described above will be described in detail with reference to FIG. 3.

In the method of controlling a product of a home network system according to the present invention, first, when a command data packet is received from the home server 2, each of the home appliances 1a to 1n grasps a recipient address of the received command data packet.

At this time, the flag of the most significant bit (MSB) indicating whether the individual address or the group address in the recipient address is determined (S10).

As a result of the determination (S10), if the most significant bit of the recipient address has a value of 0, that is, if it is an individual address, each of the home appliances 1a to 1n compares the recipient address composed of the product type and the logical address with its own address. For example, home appliances that are the same as their addresses process the corresponding orders, while home appliances that are not the same as their addresses ignore the orders (S11 to S13).

On the other hand, the determination result (S10), if the most significant bit of the recipient address has a value of 1, that is, if the group address to determine the product type and location code of the grouped address.

As a result of the determination, if the product type is all products (FF) and the location code is all positions (FF) in the address of the receiver, that is, if all group positions (OxFFFF) for all products (FF) at all positions (FF) All home appliances FF in FF perform the corresponding command (S20, S12).

On the other hand, if the group address (OxXXXX) for a specific product (XX) of a specific location (XX) (hereinafter, XX means any particular location or specific product type), the specific product (XX) located at the specific location (XX) The home appliance corresponding to) performs the command (S30 to S31, S12).

And, if the group address (OxFFXX) for all products (FF) of a specific location (XX), all home appliances (FF) located in the specific location (XX) performs the command (S40, S31, S12).

In addition, if the group address (OxXXFF) for a specific product (XX) of all locations (FF), the home appliance corresponding to the specific product (XX) located at all locations (FF) performs the command (S50, S12).

Therefore, the present invention can realize this in a single command data transmission when the address of the receiver is to be grouped according to the product type or location to control multiple home appliances for the same command.

The product control method of the home network system according to the present invention described above can be controlled by grouping the address of the receiver according to the product type and location to control a plurality of home appliances with a single command data transmission, thereby minimizing the generation of traffic in the network. There is an effect to improve the reliability and performance of the system.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
