Wireless communication frequency hopping method

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...
