No metal security screening gate alarm

Scientific definition of magnetic field at security gate

Usually, we can ignore the weak magnetic field, because the weak magnetic field is equivalent to the effect we have in the middle of the geomagnetic field. The earth’s magnetic field has always existed, but it does not have much impact on us. However, the impact of strong electromagnetic fields on the human body cannot be ignored. Generally speaking, the country stipulates that the magnetic field of electrical appliances is within 3 Within 0UT, the impact on the human body can be ignored. Generally, when the security screening gate is working, its magnetic field strength will not exceed 10UT, which can be said to be completely safe. However, some security screening gate manufacturers cannot meet the detection requirements at low power due to manufacturing technology, so they start Increase the power and expand the frequency. At this time, it will be more difficult to ensure that the radiation of the security screening gate is at a normal level. However, even so, the impact of the security screening gate on people is far less than the impact of electrical appliances such as mobile phones on us. This is mainly because the electromagnetic field emitted by the security screening gate is mainly 6.8~ The magnetic field between 8KHZ and MHZ is generally very harmful to the human body. Therefore, it can be said that passing through the security gate will not have a big impact on pregnant women. Even if they pass through it hundreds of times a day, the radiation they receive in a week is only equivalent to making a phone call on a mobile phone.

The next step is to accept a AOCTRON metal security screening gate

Safety performance of metal security screening gates

The power supply of the whole machine is placed on the top of the host, and the power of the whole machine can be controlled by the remote control. It adopts an uninterruptible power supply protection system, and the battery power supply is not less than 8 hours. The system has a parameter protection function when the power is cut off. It is made of imported waterproof synthetic fiber materials and is made through precision processing technology. The LCD can be installed tilted according to the human body’s viewing angle characteristics to facilitate reading/operation. (optional)

Metal detection function

Metal detection security screening gates must have high security requirements, which include the following factors:

1. The uniformity of the magnetic field is the key to the detection rate;

2. The detection power of the security check must be sufficient to detect any hazardous metal objects, regardless of its entry position and angle;

3. The detection power of the metal detection security gate must be sufficient to detect people, no matter what speed they are passing through;

4. It also needs the ability to detect ferrous metals and non-ferrous metals.

Detection area of metal security screening gate

Based on the basic structure of the human body, it is divided into 12 overlapping mesh detection areas. Interactive transmitting and receiving to accurately determine the location of metal objects. Eliminate weak areas and blind areas in the detection area, resulting in higher sensitivity and more stable performance. Bilateral through-beam infrared scanning quickly captures induction signals, eliminating detection errors caused by induction lag when human bodies pass by, and automatically counts the number of people passing through. The 12 main detection areas have 1000-level sensitivity programs, which can pre-set the possible locations, volume, weight, and size of metal objects according to actual usage conditions for appropriate sensitivity adjustment.

Tell me, is there any electrical radiation at the security gate?

Any electronic product has a certain amount of electromagnetic radiation. There is also a lot of electromagnetic radiation around us. Such as radio stations, TV stations, mobile phone towers, high-voltage lines, computers, TVs, microwave ovens, induction cookers, mobile phones, etc. It is not difficult to see from the above table that, like other electronic equipment, security screening gates will also produce radiation when used, but compared to these electronic products, the electromagnetic radiation of security screening gates is minimal.
