Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of security gate, concretely is an airport traffic security gate. BACKGROUND

[0002] The security gate for airport is also called security door, which is a detection device for detecting whether the person carries metal articles, also called metal detection door. The metal detection security door is mainly applied in airport, station, large meeting and other public places with large flow to check the hidden metal articles on the body of the person, such as gun, controlled knife and the like. A few high-grade security doors on the market can achieve that when the person to be inspected passes through the security door, the metal carried on the body of the person exceeds the parameter value set in advance according to weight, quantity or shape, the security door alarms immediately, and the position of the metal causing the alarm is displayed, so that the security personnel can find the metal articles carried by the person in time. Most of the security doors for factory only distinguish whether the metal articles are carried, and the position is located and alarmed to prevent the products from being taken out of the factory illegally. The best security door can detect the article of the size of the paper clip, and is suitable for public places: including gymnasium, entertainment place (disco, dance hall and the like), airport, railway station, bus station, port, exhibition hall, museum, bank, oil depot, power station and the like, the security door is originally generated 3.5-4.95M sine oscillation by crystal oscillator, is divided into 7.6K sine wave by frequency divider, is inputted into the electromagnetic wave emission of door plate (7 area) large coil after power amplification by triode and coil, is received by 1-6 area coil in the door. After receiving, the received signal is compared with the reference signal, the change is found, the output level of the acquisition card is changed, and the CPU scans the data of the six area acquisition cards within 280 milliseconds, judges the area of the metal and outputs the display. The metal detection door (security door) is the first line equipment and facility of the security of the control area, and is used for checking and filtering the harmful and attacking metal such as knife, gun, bomb and the like. In addition to becoming the security device necessary for each airport, the prison, large sports meeting place, exhibition hall, bank, court, mint, treasury, government agency, embassy, military and police unit, telecommunication machine room, various precious metal industry, electronic industry, entertainment place and the like, these places need to protect the safety of the crowd and place are widely used to avoid hijacking, danger and theft.

[0003] The stability of the security door is essential, which is the primary condition for customers to choose and purchase the security door. Unstable security door will cause false alarm and missed alarm phenomenon, making the staff at a loss, and the security door does not play a real role. Since the sensor of the security door (i.e. the two side plates of the door body) is outwardly open, it can both emit electromagnetic waves to the external environment and receive electromagnetic waves generated by the external environment. There are many devices in the external environment that can radiate fusion electromagnetic field outward, such as high-voltage lines, large motors, electric welders, intermediate frequency furnaces, interphones, etc. These magnetic fields will interfere with and affect the normal detection of the security door; therefore, all security doors will be more or less disturbed by the external environment. The manufacturers with technical strength can solve the stability of the security door itself and handle the external interference, so that the interference degree of the security door is minimized.

[0004] Generally, the security door should be designed with a real-time signal strength indicator light, which can display the size of the metal object and the strength of the interference signal. The real-time signal indicator light plays a very important role in the initial installation and use. In the initial installation and use, the security door can be adjusted to the appropriate detection parameters according to the indication of the signal light, so as to minimize the interference brought by the external environment, thereby improving the detection accuracy of the security door. Some production enterprises cancel this signal light in order to hide from people, or turn it off when no one passes, so that the user thinks that the security door is working normally; however, the security door is always in an unstable state at this time, and it will alarm whether you carry metal or not. The security door with signal strength indicator light can adjust the working parameters according to the interference intensity during installation, eliminate the influence of external interference on the security door, and ensure the normal work of the security door. The security door has an environmental self-checking function, effectively achieving anti-interference and interference elimination.

[0005] Select the same environment (including the same power supply and external electromagnetic interference) for testing: power on, block the infrared beam device to remove the infrared limit alarm function. Set the alarm sensitivity to a relatively sensitive (higher) level, and let the security door be in alarm waiting. At this time, observe the number of signal lights that are bright. If there are many bright lights, even false alarms, try to change the working frequency of the security door to avoid the interference of the external adjacent frequency, until the signal light is the least bright. If the working frequency is changed and the security door still works unstably or even false alarms, it means that the stability and anti-interference ability of the security door itself are poor. Compare various types of security doors one by one, and select the best one under the same detection ability (detecting the same kind of metal object).

[0006] The security door can alarm metal objects passing through because the two door panels are equipped with sensors that can emit and receive alternating electromagnetic fields. When the metal conductor is excited by the alternating electromagnetic field, eddy current is generated in the metal conductor, and the current emits a magnetic field with the same frequency as the original magnetic field but opposite direction. The metal detector detects whether there is metal nearby by detecting the eddy current signal. The transmitter emits excitation electromagnetic waves, and the receiving sensor receives the signal of the metal object. The receiving sensor detects the signal generated by the eddy current, and then processes the signal through a series of amplification circuits. When the signal reaches a set value, an audible and visual alarm is generated. The existing airport traffic security gate is fixed and inconvenient to move. Content of the utility model
