Embodiment 1

[0037] An adaptive frequency hopping method of the present invention is applicable to a remote controller and a terminal.

[0038] See attached figure 2 , including the following steps:

[0039] Step S1 1. After power on, the main control chip determines the working mode of the main device.

[0040] The main control chip (MCU) can select the master device working mode (as a signal sending end) and the slave device working mode (as a signal receiving end) through its own pins.

[0041] One of the characteristics of the present invention is that the wireless remote controller temporarily or temporarily acts as a "slave device" of the master device in other communication systems in the self-adaptive frequency hopping control. And the working state of the wireless remote controller is automatically switched by its own internal computer program.

[0042] Step S2 1. The main control chip initializes the transceiver chip through the three-wire SPI, and sets the transceiver ch...

Embodiment 2

[0054] An adaptive frequency hopping method of the present invention is applicable to a remote controller and multiple (m≥1) terminals.

[0055] See attached image 3 , including the following steps:

[0056] Step S1 1. Power on, the main control chip determines the working mode of the remote control as the main device.

[0057] Step S2 1. The main control chip initializes the transceiver chip through the three-wire SPI, and sets the transceiver chip to work in channels 1 to m in sequence.

[0058] Step S3 , the main control chip controls the transceiver chip to broadcast the channels of integer multiples of m with the initial operating frequency, to detect whether there are co-frequency receiving devices on the channels of integer multiples of m, and store the detection results of integer multiples of m in the main in the memory of the control chip. The integer multiple is reasonably determined according to the frequency bandwidth.

[0059] If there is a connection be...

Abstract

The invention discloses a self-adaptive frequency hopping method and a computer readable storage medium. A master device (such as a wireless remote controller) sends out a channel detection signal in self-adaptive frequency hopping control, temporarily or temporarily serves as a slave device of a master device in other communication systems, detects the channel occupation condition, and selects the most favorable channel to instruct the slave device to carry out frequency hopping communication. The self-adaptive frequency hopping method is simple and efficient in implementation means.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to an adaptive frequency hopping method and a computer-readable storage medium. Background technique [0002] The 2.4G frequency band is a globally open license-free industrial frequency band, especially suitable for short-distance communication. Since the 2.4G frequency band is narrow and there are many users, it is easy to generate potential interference from other devices using the same communication technology and devices using other communication technologies in the same frequency band, seriously affecting the communication quality, and even destroying the communication between the two parties. For example, Bluetooth technology operates in the same 2.4GHz ISM band as Wi-Fi and technologies using the IEEE 802.15.4 standard. [0003] Therefore, frequency hopping technology is usually used for communication in the 2.4GHz frequency band, and a series of ...
