Embodiment Construction

[0019] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0020] refer to figure 1 The method for detecting communication interference of the wireless module of the present invention will be described. The method mainly includes the following steps:

[0021] Step 100 , before starting to detect communication interference, firstly set a SNR reference value, an initial value of error frame EDV and an error frame EDV threshold. Wherein, the error frame EDV threshold should be smaller than the error frame EDV initial value, the error frame EDV initial value is recommended to be a natural number greater than 5, for example, 8, and the error frame EDV threshold is recommended to be 2.

[0022] Step 101, start the communication interference detection function of the wireless module, and the starting action can be realized by inputting a correspondin...

Abstract

The invention discloses a method and a device for detecting wireless module communication interference. The method comprises the following steps: S1. setting each preset value relevant to SNR (Signal Noise Ratio) and an error frame; S2. starting communication interference detection; S3. detecting SNR in a cell, comparing the SNR with an SNR reference value, and performing step 4 only when the SNR is less than the SNR reference value; S4. When an error frame is received, subtracting 1 from the current value of the error frame EDV (Error Detection Value); S5. comparing the current value of the error frame EDV with the threshold value of the error frame EDV, and performing step 6 only when the current value of the error frame EDV is less than the threshold value of the error frame EDV; and S6. prompting that the communication interference exists. The method and the device can be used for quickly and accurately detecting the existence of the communication interference.

Description

technical field [0001] The invention relates to communication interference detection technology, in particular to a wireless module communication interference detection method and a corresponding wireless module communication interference detection device. Background technique [0002] During the normal communication process of the wireless module, once the user enters an area where jammers interfere with the communication frequency band, such as an area with full-band industrial jammers, it will suddenly occur that they cannot make calls or perform all normal communication activities. Case. At this time, if the user cannot know the cause of the communication interruption in time, he will not be able to take correct countermeasures to quickly solve the communication failure, such as avoiding the area with jammers in time, or activating certain security measures, etc. This will inevitably bring great inconvenience to the user. However, the current wireless modules just lack...
