Embodiment Construction

[0019] The specific implementation manner of the present invention will be further described below in conjunction with a specific example. The wireless communication frequency hopping method provided by the present invention is used to re-establish a connection after a communication disconnection, and belongs to a passive frequency hopping method, that is, the frequency hopping is performed only after the communication disconnection, and the frequency hopping is stopped after the communication connection. This embodiment includes one master terminal and one slave terminal, and the present invention also includes embodiments of multiple master terminals and one slave terminal, one master terminal and multiple slave terminals, or multiple master terminals and multiple slave terminals.

[0020] Such as figure 1 and figure 2 Shown are the work flow diagrams of re-establishing the connection after the master end and the slave end are disconnected. In this embodiment, the steps o...

Abstract

A wireless communication frequency hopping method is disclosed and comprises the following steps: a plurality of wireless frequency points are preset, and a master terminal sends out predetermined format data; if return data from a slave terminal is received in preset time, communication connection is successfully established; otherwise the master terminal repeatedly sends out the preset format data and again confirm whether the return data from the slave terminal is received; if the return data from the slave terminal is not received when the times for which the master terminal sends out the preset format data reaches a preset number, the master terminal hops to another wireless frequency point and continues sending the preset format data after sleeping for a first time, and the preset format data sent from the main terminal is received by the slave terminal according to a fixed cycle; if the preset format data is received in a cycle, the data is returned to the master terminal, and communication with the master terminal is kept at corresponding frequency points; otherwise, the slave terminal hops to another wireless frequency point, and the master terminal and the slave terminal have a fixed frequency hopping sequence. The method is advantaged by simplicity, high efficiency and high reliability.

Description

technical field [0001] The invention belongs to the field of wireless communication, and relates to a frequency hopping method for wireless communication, which is applicable to the process of re-establishing connection after communication disconnection of various wireless communication terminals such as remote controllers and display panels and devices using the method. Background technique [0002] Existing wireless communication technologies have some common communication protocols in the 2.4GHz frequency band, such as Bluetooth, WiFi, Zigbee, etc. These protocols have some disadvantages in the process of re-establishing connection after some actual products, especially bathroom products, are disconnected, such as long reconnection time (most of the above three communication protocols take more than 4 seconds), low reconnection success rate, and low power consumption. Large and other problems are not conducive to energy saving, high implementation costs, and complex proto...
