Switching method and switching device of wireless communication mode

Abstract

The invention provides a switching method and a switching device of a wireless communication mode. The method comprises the steps of when a key event is monitored and a key command is determined to be sent into a controlled device, determining whether the recorded state of a first wireless fidelity (WiFi) module arranged an intelligent remote controller and a second WiFi module arranged on the controlled device is a connection state or not; if the recorded state of the first WiFi module and the second WiFi module is determined to be the connection state, determining whether the first WiFi module and the second WiFi module reach the preset condition of establishing connection or not; if the first WiFi module and the second WiFi module are determined to reach the preset condition, establishing a communication connection between first WiFi module and the second WiFi module, and sending the key command into the second WiFi module by the first WiFi module; if the first WiFi module and the second WiFi module are determined not to reach the preset condition, sending the key command into the controlled device by an infrared module arranged on the remote controller. After the method and the device are used, excessive useless connection requests which are sent into the second WiFi module by the first WiFi module can be avoided, so that the power consumption of the intelligent remote controller can be reduced, and the service life of a battery of the intelligent remote controller is prolonged.

Description

technical field [0001] The present invention relates to the field of smart home technology, in particular to a method and device for switching wireless communication modes. Background technique [0002] Infrared remote controllers are the most commonly used remote controllers in households. Using infrared rays to communicate can avoid radio interference, and the infrared remote controllers have low manufacturing costs and high stability. However, since the infrared signal is not encrypted, if there are multiple controlled devices of the same type in an environment, it is easy to use the same remote control to remotely control multiple controlled devices at the same time, thus bringing unnecessary operations to the user. [0003] WiFi wireless remote control is gradually becoming popular in smart remote controls. The WiFi remote control signal can remotely control the controlled device from all angles in the room. Compared with the above-mentioned infrared remote control, t...

Problems solved by technology

In the existing technology, due to the advantages of WiFi over infrared, the controlled device is usually started and shut down by infrared, and the WiFi communication mode will be used first when in use. If the connection request command sent by WiFi fails, it will be switched again immediately. In WiFi mode, if the WIFI module on the controlled device is turned off, even if the remote control sends a connection request command to the controlled device through the WiFi module, the WiFi module on the remote control cannot establish a communication connection with the WiFi module on the controlled device. In this case, the WiFi module on the remote controller may initiate many useless connection requests to the WiFi module on the controlled device, and too many useless connection requests increase the power consumption of the remote controller
