Problems solved by technology

Since the metal detection technology is aimed at the detection of metal objects, when detecting mobile phones and similar products, a large number of false alarms of other metal objects will inevitably occur.
And there is also electromagnetic radiation exceeding the national standard, which is not suitable for workplace applications
[0004] In the process of realizing the present invention, it is found that at least there are disadvantages such as high false alarm rate, low reliability, and excessive electromagnetic radiation in the prior art

Embodiment

[0039] The detection door includes a plurality of magnetic sensors, an electric control system, and a door structure cooperating with them.

[0040] Such as figure 1 As shown, the door body structure mainly includes: bottom pedal 1, main detection column 2, auxiliary detection column 3, data processing system box 4, infrared beam sensor 5;

[0041] The bottom pedal 1 is detachable. A pair of main detection columns 2 are vertically symmetrically arranged on both sides of the bottom pedal 1, and a pair of auxiliary detection columns 3 are vertically symmetrically arranged on the side of the pair of main detection columns 2 away from the bottom pedal 1. On both sides of the bottom pedal 1 and below the main detection column 2 and the auxiliary detection column 3 is a data processing system box 4 .

[0042] A group of infrared through-beam sensors 5 are installed symmetrically along the direction of the main detection column 2 on the bottom pedal 1, which are respectively a tran...

Abstract

The invention belongs to the weak magnetic detection technology field, and particularly relates to a communication recording device detection door based on a magnetic sensor. The invention provides a communication recording device detection door based on the magnetic sensor, which has the advantages of high anti-interference capability, high detection rate and low false alarm rate; and the detection rate is not influenced no matter a mobile phone is in flight mode, sleep mode or shutdown state. A passive detection principle is adopted, therefore, human health is safe, and no electromagnetic radiation happens.

Description

technical field [0001] The invention belongs to the technical field of weak magnetic detection, and in particular relates to a detection door for communication and recording equipment based on a magnetic sensor. Background technique [0002] With the development of science and technology, more and more security inspections in confidential places require the detection of communication recording equipment. Common communication recording devices include: voice recorders, cameras, mobile phones, earphones, microphones, walkmans, etc. At present, there are three most commonly used technical means on the market, namely: signal jammers, hand-held detectors, and metal detection doors. The signal jammer cannot prevent the camera, recording pen, mobile phone, etc. from taking photos and recording functions or Trojan horse viruses from causing leaks. In addition, the electromagnetic waves emitted by jammers can also affect your health. Hand-held detectors are cumbersome and complica...
