Anti-interference method, device and equipment and readable storage medium

Abstract

The invention discloses an anti-interference method, device and equipment and a readable storage medium. The method comprises the following steps: determining a minimum value and a maximum value in a first working frequency value range of a radio frequency module; calculating a first ratio of the minimum value to the to-be-measured frequency value and a second ratio of the maximum value to the to-be-measured frequency value; wherein the to-be-measured frequency value is the working frequency value of the interference source; and if the difference value between the first ratio and the second ratio meets the preset condition, determining that the to-be-measured frequency value does not interfere with the radio frequency module, and controlling the interference source to work at the to-be-measured frequency value. No matter how the working frequency of the radio frequency module changes, the selected frequency value to be measured does not influence the normal work of the radio frequency module, so that the working frequency of the interference source does not need to be frequently adjusted, the normal work of the radio frequency module and the interference source is ensured, and the anti-interference is realized on the premise of not increasing the hardware cost. The anti-interference device and equipment and the readable storage medium provided by the invention also have the above technical effects.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an anti-jamming method, device, equipment and readable storage medium. Background technique [0002] At present, smart devices (such as smart watches, VR devices, AR devices, etc.) have more and more functions, and the density of devices is getting higher and higher, and the self-interference phenomenon of the whole machine is becoming more and more serious. Interference sources that generate interference include modules such as display screens and cameras in smart devices. The operating frequency of these interference sources will interfere with the radio frequency module in the smart device. Radio frequency modules such as: 4G / 5G modules, WiFi modules and other hardware modules with communication functions. [0003] The general solution is: add a filter circuit to the hardware circuit, and strengthen the grounding measures, or change the spatial layout of ...

AI Technical Summary

Problems solved by technology

However, due to the high cost of changing the hardware circuit, and the effect varies greatly, the interference problem cannot be completely solved, and the circuit layout will also lead to poor consistency, which is inconvenient for mass production and implementation.
