The security checkpoint may only be a security equipment for us, but it is an indispensable part of society. Without security screening machines, social order lacks stability, so security screening machines are very important to society. Next, let's take a look at the specific content:

What contribution does the security checkpoint make to society? Security gates are now widely used in various industries, and it is expected that households will use security gates in the near future. Stay away from danger and open the anti-theft door.

Security gates contribute to production enterprises by preventing the theft of raw material prices such as copper, aluminum, tin, nickel, etc., which can lead to related industries such as hardware, electroplating, electronic appliances, wire and cable, mechanical casting, etc. Semi finished products and components are steadily increasing. It is precisely because these precious metals are so expensive and have many recycling points. Some employees with malicious intentions can use them to prevent the loss of valuable metals.

Enterprises attempt to prevent and reduce the loss of metal materials. Practice has proven that the application of security gates can scientifically, objectively, human-oriented, and effectively prevent and stop incidents in factories. This is because the security checkpoint has the characteristics of high detection accuracy, adjustability, objectivity, no human interference, no need for search, respect for employees, fast speed, and easy operation.

With the progress of the times and the rapid development of science and technology; The application of security gates in research institutes. According to regulations, commercial dance halls, bars, and other facilities will be equipped with safety inspection equipment and relevant personnel will undergo safety checks to avoid similar incidents.

Conduct security checks on customers entering this category, and ensure that their clothing, carry on keys, coins, belt buckles, metal zippers, mobile phones, and other metal items are all shielded by alarms and exceed their capacity.

The above-mentioned metal items are warned to prevent customers from carrying, controlling, and other weapons into consumer areas, thereby preventing combat incidents, ensuring the safety of consumers' lives and property, and the property and reputation of operators.

Environmental requirements: The security checkpoint is suitable for installation outside the entrance of the gate or inside the passage of the gate. When working at the security checkpoint, there should be no large metal objects within a 1-meter radius to prevent unnecessary interference and ensure accuracy.

The security checkpoint can generate an alarm for passing metal objects because the two side door panels are equipped with sensors that can emit and receive alternating electromagnetic fields. When a metal conductor is excited by an alternating electromagnetic field, eddy currents are generated in the metal conductor, which in turn emit a magnetic field with the same frequency as the original magnetic field but in the opposite direction. The metal detector detects the presence of metal objects nearby by detecting the presence or absence of the eddy current signal. The excitation electromagnetic wave is emitted by the transmitter, and the signal of the metal object is received by the receiving sensor. The receiving sensor detects the signal generated by the eddy current and then amplifies it through a series of circuits. When the signal reaches the set value, an alarm is generated in the form of sound and light.

Security inspection is a responsible undertaking, as well as a combination of concepts and technology. This field is extensive and requires professional and socially responsible practitioners and professionals. Security checkpoint products have been widely used in various public places and enterprises. If inferior products that do not meet product safety and quality requirements are used to ensure public safety, it will bring extremely unstable factors to public safety. This is the shame and concern of the security checkpoint industry.

Therefore, it is necessary to strengthen and accelerate the formulation and implementation of industry standards, strengthen market supervision, conduct strict qualification assessment and mandatory certification, not only traditional safety certification, but also product specific performance certification (such as the impact of metal detection magnetic induction radiation intensity on personal health and safety, and waterproof performance, etc.). Raise the threshold for production and market entry, standardize product promotion, crack down on false advertising, in order to form an orderly market competition and reflect the social responsibility of practitioners.
