Embodiment Construction

[0084] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0085] In related technologies, when there is interference in the working frequency band where the current communication channel is located, usually the working frequency can be switched to a pure frequency band without interference to ensure communication quality. However, if the electromagnetic environment in which the wireless communication system is located is complex and changeable, and there are a large number of discrete narrow-band interferences in the channel, within the frequency range supported by the system, when a pure frequency band that is sufficient to accommodate the current working bandwidth cannot be found, the discrete frequency band that f...

Abstract

The purpose of the present disclosure is to provide a method and device for switching channels, a storage medium and electronic equipment, so as to solve the problem in the related art that wireless communication is prone to poor communication quality due to narrowband interference. The method includes: detecting whether the signal-to-noise ratio information of the working frequency band where the communication channel is located satisfies a first preset condition; if the first preset condition is not met, determining a target bandwidth that is larger or smaller than the bandwidth of the working frequency band; Obtain the signal-to-noise ratio information of the frequency band to be detected with each preset frequency point in the preset frequency range as the center frequency point and the target bandwidth as the bandwidth; according to the acquired multiple frequency points to be detected The signal-to-noise ratio information of the frequency band, judging whether there is a target frequency band whose signal-to-noise ratio information meets the second preset condition in the multiple frequency bands to be checked; if there is the target frequency band, switching the communication channel to the target frequency band .

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a method and device for switching channels, a storage medium, and electronic equipment. Background technique [0002] The channel of wireless communication is easily affected by factors such as noise and interference. In addition, because wireless communication devices are often mobile, this will bring unpredictable randomness to the wireless channel, which poses challenges to the reliability of high-speed communication using wireless channels. Especially in the ISM (Industrial Scientific Medical) frequency band, since the use of this frequency band does not need to be authorized by the Radio Regulatory Commission, there are various types of civil radio equipment working in this frequency band, such as various types based on Wi-Fi, Bluetooth and ZigBee technologies. Wireless equipment, and various special equipment used in industrial production and scientifi...
