Problems solved by technology

[0004] When the geographical location of the wireless device moves, the interference situation of the electromagnetic environment where the wireless device is located is often very different. For wireless devices working at fixed frequency points, it is difficult to ensure that they have the same anti-interference performance in different geographical locations. Resulting in reduced communication reliability and stability for wireless devices
If you rely on the user to manually change the operating frequency or set it offline, it will affect the continuity, stability and reliability of data transmission by the wireless device

Embodiment approach

[0111] The first implementation manner is: the currently collected observation value of the electromagnetic environment is used as the parameter value of the electromagnetic environment where the transmitting and receiving ends currently coexist.

[0112] The second implementation mode includes the following steps:

[0113] Adding the observed values ​​of the electromagnetic environment collected multiple times in history to the circular queue of preset length in order of acquisition;

[0114] determining the mean value of the remaining values ​​in said circular queue except for the minimum value;

[0115] Comparing the average value with the observation value collected last time in the circular queue;

[0116] The parameter value is determined to be the larger of the average value and the observation value collected last time in the circular queue.

[0117]In the embodiment of the present disclosure, the observed value collected in real time may be used as a parameter value...

Abstract

The disclosure relates to a frequency point switching method, device, storage medium and wireless equipment, so as to accurately perform frequency point switching to avoid interference and effectively reduce the occurrence of wrong switching. The frequency point switching method includes: determining the parameter value of the electromagnetic environment where the two ends of the transceiver currently coexist, and the parameter value at least includes: the actual value of the signal-to-noise ratio SNR and the actual value P of the received power of the receiving end r ; Determining the theoretical value of received power in a non-interference environment and the theoretical value of the signal-to-noise ratio in a non-interference environment under the current actual distance between the two ends of the transceiver. The difference of value SNR is beyond the allowable range of signal-to-noise ratio error S c , and the theoretical value of received power and the actual value of received power P r The difference is within the allowable range of received power error P c When the time is within, frequency switching is triggered, so that the operating frequencies of the transmitting and receiving ends are synchronously switched to the target frequency.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular, to a frequency point switching method, device, storage medium, and wireless device. Background technique [0002] The ISM (Industrial Scientific Medical) frequency band is also known as the unlicensed frequency band. The use of this frequency band does not require authorization from the Radio Regulatory Commission. There are many types of wireless devices operating in this frequency band, resulting in many unpredictable sources of interference in the ISM frequency band. Therefore, the anti-jamming capability becomes one of the important indexes to measure the performance of the wireless equipment working in the ISM frequency band. [0003] At present, most wireless devices working in the ISM frequency band work with a fixed frequency point, that is, the manufacturer has set the working frequency point to a fixed value when the device leaves the factory, ...
