Transmission method of household appliance local area network

Abstract

The invention provides a transmission method of a household appliance local area network for solving the problem that when working at the same time, a plurality of existing household appliances cannot respond in time. The transmission method can solve the problem that under the situation of a module 433 selected at present, the household appliances cannot respond in time when working at the same time. The transmission method of the household appliance local area network comprises the steps that firstly, a gateway unit sends out a networking order, and the household appliances needing to have access to the network have access to the network in sequence; secondly, the gateway unit allocates corresponding network IDs to the household appliances having access to the network according to the network accessing sequence; thirdly, the gateway unit determines which transmission mode is needed to transmit data according to the order, wherein if the order is a broadcast order, the time quantum dividing method is adopted so that the different household appliances in the network can transmit the data in the corresponding quantum, and if the order is a single household appliance order, the method of monitoring a channel firstly and then carrying out transmission is adopted to transmit data; fourthly, if the gateway unit is subjected to strong wireless interference in one channel, the channel conversion method is adopted 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 for home appliance local area network. Background technique [0002] Currently, with the rise of smart home R&D, the interconnection of white goods and lighting has been on the agenda. However, how to perform better wireless transmission between home appliance LANs has always troubled relevant technical personnel. Because the interconnection of home appliances is not the same as the interconnection of mobile phones and black power products, the main difference is in its underlying transmission. The characteristics of the underlying transmission of home appliances interconnection are low cost, easy installation, small data volume, and number of devices. Many, timely response, moderate indoor transmission distance. Therefore, we cannot just copy the current underlying transmission method of black power products. According to the chara...
