What are the applications of people screening?

People screenings have come a long way as far as their history and design. People screening plays a huge role in maintaining safety and reducing violence. A number of public places around the world invest in people screening for good reason. With the help of trained personnel and monitored usage, people screening helps detect dangerous objects with metal such as knives and guns. The people screening has increased the effectiveness in detecting unwanted items when it is used with hand-held detection devices.

What technology does people screening have?

While a people screening can detect the contrabands, there are sure to be a number of complex concepts and technical points. But the most important technology for people screening is the Pulse Induction System or PI. Most metal detectors are based on this system. PI system includes having a special coil placed in the middle of the people screening while running through both sides and the top. The coil has special transmitters and receiver signals that pick up or detect metal material that passes through the main opening or where you walk through.

There are special magnetic forces of people screening that detect metal very quickly, literally in microseconds through pulse ranges at a thousand per minute. The electromagnetic field is made when the metal material passes through and causes the pulse in the people screening to react. The field range may vary depending on the setting of the people screening and the type of metal detected. Some types of metals are detected more quickly than others.

People screening works by using the principle of electromagnetism. When this electric field passes over a metal object, the field passes right through it. The electrons in it are induced to move and produce a magnetic field of their own. In addition, it also creates a secondary magnetic field as well which is detected by the people screening. The first coil induces the magnetic field into the metal object that a person might be carrying, whiles another coil in the people screening picks up this potential secondary magnetic field and accordingly sets off an alarm.

What should be paid attention when using people screening?

Among all types of people screening except for fully rainproof people screening, other types of people screening should not be exposed to rain. It is necessary to cover the canopy when being transported to prevent damage to the people screening.

There should be no large metal objects within 1 meter around the people screening, such as large iron doors, elevators, and large iron pillars.

When the people screening is installed, it is necessary to install people screening step by step according to the prescribed procedures. People screening must be fixed and reliable to prevent from shaking due to strong wind or bumps.

The people screening should be far away from objects that generate magnetic fields, such as distribution boxes and electrical equipment.

The installation site of people screening should be selected in the workshop with only one exit channel. An independent inspection area is set on the side.

Draw a pedestrian passage on the ground with a stop line from half a meter to one meter in front of the people screening. Employees must walk through the pedestrian passage when they leave. When the person in front passes through the people screening, the person behind must wait at the stop line to wait for the person completing before passing the people screening.

What are the applications of people screening?

When we go through the airport security check, many people can directly see the people screening. Many people don't know the people screening very well. They don't know why they didn't carry anything dangerous, but the people screening alarms when they passed from there. It is possible that we carry electronic products or electrical appliances, including voice recorders and precious metals.

The people screening is suitable for production-oriented enterprises, including electronics such as hard disks, mobile phones, MP3, translators, voice recorders, electronic devices; wires and cables; electrical appliances; gold and silver jewelry; mining; hardware products; precious metals such as copper and aluminum; and processing related industries.

The people screening is mainly used for all government departments, including the Municipal Public Security Bureau, courts, prisons, and detention centers. However, people screening is also suitable for use in public places, such as the entertainment venues and dance halls we often go to. Therefore, the people screening should be applied to these occasions.

The second applicable public places for people screening include stadiums, entertainment venues, airports, railway stations, bus stations, ports, exhibition halls, museums, banks, power stations, hotels, courts, prisons.

Therefore, the people screening plays a very important role in our daily life. And people screening not only gives more safety guarantees to others, but also gives a lot of safety guarantees to ourselves.
