Problems solved by technology

The shielding principle is to effectively block the signal network, so that it cannot obtain a link connection with the strongest signal or the nearest base station, destroying the connection between the mobile phone and the base station, making the mobile phone separated from the base station and unable to perform its functions

specific Embodiment approach

[0031] With reference to the drawings, the specific implementation is as follows:

[0032] A mobile communication signal interference protection evaluation method, such as figure 1 As shown, including the following steps:

[0033] Step 1. Set the measurement points in the actual scene, and respectively measure the signal strength at each actual measurement point before and after the jammer is turned on at the predetermined frequency f, where the type of the previously measured signal strength measured before the jammer is turned on is the peak power P Actual measurement_before , The measured signal strength type after the jammer is turned on is the minimum power P Measured_after .

[0034] The data measurement for the actual scene, that is, the target scene, mainly includes the following two parts:

[0035] (1) Measurement of signal strength.

[0036] First select the measuring point. In the actual measurement process, the selection of measurement points cannot be infinite, so select...

Abstract

The invention relates to a mobile communication signal interference prevention assessment method and system. According to the mobile communication signal interference prevention assessment method and system of the invention, in a given context, points are reasonably distributed, and then, a professional measuring instrument is adopted to measure actual values; a time domain finite difference algorithm and a non-parametric regression algorithm are adopted to predict signal strength respectively; analysis and correction are performed on a result through optimizing parameters in a prediction algorithm, and an interference-to-signal ratio can be obtained through calculation; the interference-to-signal ratio is compared with an actual interference effect, so that an interference prevention assessment index system can be obtained; full-range prediction and assessment are carried out; and therefore, the interference prevention effect of mobile communication signals can be judged.

Description

Technical field [0001] The present invention relates to mobile communication interference evaluation technology, in particular to a mobile communication signal interference protection evaluation method and system. Background technique [0002] A mobile communication jammer is a portable device that shields mobile devices in order to ensure the order and safety of places where the use of mobile phones is prohibited, such as governments, financial institutions, prisons, hospitals, examination rooms, gas stations, and important meetings. The principle of shielding is to effectively block the signal network so that it cannot obtain a link connection with the strongest signal or the nearest base station, destroying the connection between the mobile phone and the base station, and making the mobile phone separate from the base station and unable to perform its functions. The interference effect is an important performance index to measure an interference method or interference technolo...
