Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Such as figure 1 As shown, this embodiment includes a gateway unit 1 and a sub-device node unit 2 composed of several home appliances; the gateway unit 1 and the sub-device node unit 2 are connected through a wireless network for data exchange, and the gateway unit is a home appliance The master device of the local area network, each device also includes a wireless module.

[0038] Before the normal communication between the gateway unit and the household electronic equipment, a network must be established, and normal communication can only be performed after the network is formed. The networking steps of the gateway are as follows:

[0039] A. After the home electronic equipment is powered on, press the switch button for X seconds to send a networking command to the wireless module of the home appliance, and the gateway unit presses the group ...

Abstract

The present invention solves the problem that multiple household electronic devices cannot respond in time when working at the same time, and provides a transmission method for the home appliance local area network, which can solve the problem that multiple household appliances cannot respond in time when the 433 module is currently selected. . The transmission method of the home appliance LAN: 1) The gateway unit issues a networking command, and each home electronic device that needs to be connected to the network enters the network in turn; 2) The gateway unit assigns the corresponding network ID to the connected home electronic devices according to the order of network access; 3) The gateway The unit judges what kind of transmission method to use for data transmission according to the instruction. If it is a broadcast instruction, the method of dividing the time period is used to allow different home appliances in the network to perform data transmission in the corresponding time period; if it is a single household electronic device instruction, it is used. First monitor the channel, and then transmit the method to transmit data; 4) If the gateway unit receives strong wireless interference on a certain channel, it will use the method of switching channels to avoid interference.

Description

technical field [0001] The invention relates to a transmission method of a local area network. In particular, it relates to a transmission method of a home appliance local area network. Background technique [0002] At present, with the rise of smart home research and development, the interconnection of white goods and lighting has been put on the agenda. However, how to better perform wireless transmission within the home appliance LAN has been perplexing relevant technical personnel. Because the interconnection of home appliances is not the same as the interconnection of mobile phones and black electric products, the main difference is in its underlying transmission. The characteristics of the underlying transmission of home appliance interconnection are low cost, easy installation, small amount of data, and a large number of devices. Multiple, timely response, moderate indoor transmission distance. Therefore, we cannot mechanically apply the underlying transmission met...
