Embodiment Construction

[0020] The specific implementation 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 the communication is disconnected, and belongs to a passive frequency hopping method, that is, the frequency hopping is performed only when the communication is disconnected, and the frequency hopping is stopped after the communication connection. This embodiment includes a master terminal and a slave terminal. The present invention also includes an embodiment of multiple master terminals and one slave terminal, one master terminal and multiple slave terminals, or multiple master terminals and multiple slave terminals.

[0021] Such as figure 1 with figure 2 Shown are the working flowcharts of re-establishing the connection after the master and slave are disconnected. In this embodiment, the steps of the wireless frequency...

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 is a frequency hopping method of wireless communication, which is suitable for various wireless communication terminals, such as remote controllers, display panels, etc., to re-establish connections after communication is disconnected and devices using the method. Background technique [0002] The existing wireless communication technology has some general communication protocols in the 2.4GHz frequency band, such as Bluetooth, WiFi, Zigbee, etc. These protocols have some drawbacks in the process of re-establishing the connection after the disconnection of some actual products, especially sanitary products, such as long reconnection time (most of the above three communication protocols take more than 4 seconds), low reconnection success rate, and power consumption Large-scale problems are not conducive to energy saving, high implementation costs, and complicated protocols. In addition, when m...
