Metal detector price manufacturer: metal security doors are mainly used to detect metal materials and send out alarm reminders. Applications include airports, subway stations, public security systems, culture and education, factories, event venues, and large-scale events. The working principle of the safety inspection door is to cause a sine function oscillation of 3.5-4.95M through a crystal oscillator circuit. The frequency divider is a 7.6K upper and lower sine wave. After the power amplification circuit is developed through triode and electromagnetic coil, the large electromagnetic coil of the door leaf (area 9) is input to carry out radio wave transmission, which is respectively accepted by the electromagnetic coils of area 1-8 in the door.

After the power amplification circuit is developed through triode and electromagnetic coil, the large electromagnetic coil of the door leaf (area 9) is input to carry out radio wave transmission, which is respectively accepted by the electromagnetic coils of area 1-8 in the door. After acceptance, the received data signal is compared with the standard data signal. After the change is found, the output level of the data acquisition card is changed. The CPU scanners the data of the 8 location advantage data acquisition cards within 280ms to distinguish the location advantage of the metal and export it. The simple point of view is to use the basic principle of magnetic field induction to distinguish the data signals in the area of the security inspection door. If there is metal, it will affect the electromagnetic field, so that after the change of the original electromagnetic field is identified, the alarm can be carried out according to the corresponding location advantage, and the number of people and the number of alarms can be statistically analyzed. It can also show that the metal is in the approximate part of the human body and alarm according to the sound and light effect.


Metal detector price manufacturer: then how does the mobile phone security door work? in fact, the working principle of the mobile phone security door is the same as that of the metal security door. only two kinds of security doors detect different commodities. the metal security door detects metal commodities, while the mobile phone security door only detects the mobile phone, and then removes other metal objects without generating an alarm. We all know that the purpose of mobile phone security door is relatively strong.

Price manufacturer of metal detector: through the above specific contents, the difference between mobile phone security door and metal security door must be very clear, right


Metal detector price manufacturer: first, colleges and universities are a clean place. they are all areas where Sandy students upgrade themselves and are also areas where talents are cultivated in our country. however, mobile phones, an electronic device, have brought great convenience to people, but at the same time, they also make people create many bad hazards. how can colleges and universities have to have mobile phone security doors! First, students' mobile phone obsession endangers students' autonomous learning, and second, it is a big system loophole! We all know that colleges and universities should also organize students to bring mobile phones.


Metal detector price manufacturer: security check door, everyone knows something about it. At present, the common security check door on the market is generally a general metal security check door, also known as a metal detection security check door. However, in addition to giving an alarm when metal objects are detected, the metal safety inspection door will also give an alarm to objects carried with human health. The safety inspection process is relatively complicated, especially in places with peak traffic flow and a large number of public resource networks, the high efficiency of safety inspection needs to be strengthened. This mobile phone security door can be shielded only for mobile phone alarm, because there are many kinds of objects in students' schoolbags.


Metal detector price manufacturer: therefore, through the above articles, we should be able to understand why mobile phone security doors can be used on campus!


Metal detector price manufacturer: today, I 'd like to share with you the basic knowledge of the security gate. everyone's security gate is to check whether the staff is carrying metal detection equipment, so the punishment is metal security gate. The important use of metal security doors are airports, subway stations, large-scale activities and other public places for checking people hidden metal objects, control equipment, etc. A few security gates in the market can make the security gate immediately alarm when the metal carried by the inspector from the security gate exceeds the parameters set in advance according to the net weight, total number or appearance, and indicate the location advantage of the metal causing the alarm, so that the security personnel can find the metal objects carried by the person as soon as possible. The vast majority of factory-specific security doors only identify whether to bring metal objects, fine positioning and alarm, to prevent goods from being taken out of the factory in violation of regulations. The security door with better characteristics can detect paper clip size objects.
