Embodiment

[0031] Smart home appliances, including controllers and home appliances; in wireless data communication, one of them is the main device and the other is the sub-device. If the controller is the main device, the home appliance is the sub-device; if the controller is the sub-device, the home appliance is the main device.

[0032] Such as figure 1 , a smart home appliance, comprising: a master device 1, which plays a major role in wireless communication, and is responsible for searching data channels and broadcasting data channel information on public channels. The sub-device 2 is in a secondary position in wireless communication, searches the data channel of the main device 1, and identifies and pairs with the main device 1, and then performs wireless data communication with the main device 1. The radio frequency module 3 realizes the sending and receiving of wireless data according to the commands of the main device 1 and the sub-device 2 .

Abstract

The invention relates to a wireless data communication method for an intelligent household appliance. The intelligent household appliance comprises a controller and a household appliance, wherein the wireless communication between the controller and the household appliance is realized through a radio frequency module in the controller. The controller and the household appliance in the wireless communication are respectively used as a main device and a subdevice and each of the controller and the household appliance has a sole address code respectively; communication channels comprise a common channel and a data channel. The main device selects a data channel and broadcasts information of the data channel at the common channel, the subdevice searches out the information of the data channel of the main device, and the subdevice performs code matching with the main device and then transmits wireless data. After the intelligent household appliance provided by the invention is adopted, the stability, the reliability and the anti-interference performance of wireless data transmission are improved.

Description

technical field [0001] The invention relates to the field of smart home appliances, in particular to a wireless data communication method for smart home appliances. Background technique [0002] With the diversification of smart home appliances, the complexity of functions, and the batching of control data, the stability and reliability of communication between controllers and home appliances that use wireless data transmission are more tested. Due to the limitation of the country's radio management regulations and the actual application environment, the wireless communication frequency band of smart home appliances generally adopts the 433M frequency band. The radio interference between smart home appliances is serious, and the control mode is relatively simple, making it more difficult to adapt to the wireless data transmission of future smart home appliances. development needs. Contents of the invention [0003] In order to overcome at least one defect (deficiency) of ...
