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 invention aims to provide a channel switching method and apparatus, a storage medium and an electronic device, so as to solve the problem of poor communication quality easily caused by narrowbandinterference in wireless communication in related technologies. The method comprises the steps of detecting whether signal-to-noise ratio information of a working frequency band where a communicationchannel is located meets a first preset condition or not; if the first preset condition is not met, determining a target bandwidth greater than or less than the bandwidth of the working frequency band; acquiring signal-to-noise ratio information of a to-be-detected frequency band taking each preset frequency point in a plurality of preset frequency points in a preset frequency band range as a central frequency point and taking the target bandwidth as a bandwidth; judging whether a target frequency band of which the signal-to-noise ratio information meets a second preset condition exists in theplurality of frequency bands to be detected or not according to the obtained signal-to-noise ratio information of the plurality of frequency bands to be detected; and if the target frequency band exists, 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...
