Fig. 2 is a schematic view of the structure of the boarding bridge passage; Fig. 3 is a schematic view of the installation position of the security detection device of the present invention; and Fig. 4 is a schematic view of the installation position of the security door of the present invention.

Best way to implement the invention

Figure 2 shows a preferred embodiment of the present invention. The invention arranges a material property detection device and a dangerous article shape and size detection device on an airport passenger boarding bridge, and realizes the safety detection function of the passenger boarding bridge, so that the passenger boarding bridge not only has a connection between the terminal and an aircraft The closed and comfortable transport function between passengers also has an independent security detection function. The main part of the structure of the passenger boarding bridge is composed of aisle. The aisle is divided into an inner aisle 7 and an outer aisle 8. The end of the inner aisle near the rotating platform has a structural part 9 that adjusts the length of the aisle series. The plate is mainly made of metal structures. The outer side of this part of the structure is covered with a thin steel plate, the inner side is decorated with a decorative plate, and the space is between the inner and outer sides. This space can be used to install the equipment used in safety inspection-material property detection device and dangerous goods shape and size detection device. Generally, it can be connected to the upper and lower chords 1 and 2 of the side plate of the channel through the connector. The detection device host 3 is installed in the left side plate. The right side plate is equipped with matching image intensifiers, signal image processing, and computer control systems. Related equipment 4. In this way, when the passenger passes the boarding bridge, that is, when passing through the left and right side panels, the detection device can detect the special items on the passenger and the special items in the carry-on luggage, as shown in FIG. 3.

In this section of the structural part that adjusts the length of the channel series, there are straight webs 5 on the left and right sides, and the detection door is installed at the straight webs on both sides. The test door consists of two door posts 6, which are installed inside the two door posts. It is a magnetometer. When passengers pass through the passage, if they carry metal objects, the magnetic field formed by this "door" changes, and the detection door sends out an alarm signal. In this inner space of the left and right doorposts, devices such as "microscopic eye" and "electronic nose" can also be installed, as shown in Figure 4.

The safety detection device of the present invention can be installed beside the aisle side plate sandwich of the aisle side plate to adjust the length of the aisle series of the abutment bridge on the inner part of the aisle to adjust the length of the aisle series. The place. The detection device for the shape and size of dangerous goods is used to detect a certain shape and size of special-shaped metal objects carried by passengers, such as a length exceeding a specified size, a shape similar to a firearm, a dagger, and a dangerous tool. Metal objects such as keys and nail clippers carried by passengers are not tested. Such detection devices include 1, magnetometers, 2, metal detection door, 3, a "microscopic eye" of the long-distance detector, the device can see people's clothes from 3 meters away, showing whether someone has hidden weapons or can even detect hidden Drugs and eavesdroppers, etc., work by detecting the heat radiated from the object under test. Therefore, anyone can inspect the whole body without being noticed anywhere, so it is also called "microscopic eye". 4. Microwave holography inspection instrument-Holography usually refers to holography of visible light waves. In order to find weapons hidden in clothes or wrapped in opaque materials, microwave holography is used. Microwaves are permeable to air, fog, some dielectrics, and other characteristics. A holographic device with a frequency of 70 GHz and a wavelength of 4.3 mm is used. For "electron beam inspection", you can display on the monitor screen pistols, knives and other objects hidden under layers of clothing or wrapped in synthetic leather. 5. Millimeter-wave camera A millimeter-wave camera is a device that uses the millimeter-wave focusing imaging of human body radiation. Because the amount of millimeter-wave radiation emitted by objects depends on their physical properties and temperature. The human body emits more millimeter waves than metals, ceramics, plastic explosives, powdered explosives, clothing, and insulating materials. Millimeter waves can penetrate any insulating material, all clothing and most building materials. Therefore, in front of the millimeter-wave camera, the human body is missing. Against the silhouette of the human body, coins, buttons, pens, keys, etc. are clearly visible. If you conceal any contraband such as pistols, bombs, drugs, etc., it will be even clearer. Therefore, millimeter wave cameras are the most effective means of human surveillance.

The substance property detection device is used to detect explosives and dangerous chemicals in passengers' hand luggage. This type of detection device includes: 1. Electronic nose-odor recognition system—various objects, such as drugs and explosives, have their unique odor. The electronic nose aroma scanner uses a series of high-molecular polymer sensors. When volatile molecules are inhaled from the air, the sensor can temporarily change its resistance, thereby changing the electrical signal. Analyze this change, You can determine what kind of smell it belongs to. This electronic nose scanner is used to check for dangerous goods such as drugs and explosives in airport luggage. 2. Magnetic Resonance Imaging (MRI) Baggage Scanner-This equipment is also developed using medical magnetic resonance body scanning technology. This new type of scanner uses a modified MRI called "quadrupole resonance analysis" to identify various materials from the molecular structure of the object being inspected. First, a transmitter was used to transmit low-frequency radio waves to the luggage, which instantly disturbed the nuclear arrangement inside the article. When the nuclei rearrange themselves, they emit signals that are immediately analyzed by the system's computer. Since each type of material emits a unique signal, no two compounds have the same signal. This makes it easy to detect explosives or illicit drugs. It can also detect liquid bombs, nerve gas, and other chemical weapons. This magnetic resonance explosive detection system QScan-1000 combined with Line231 X-ray safety inspection system can obtain the best detection effect. 3. Ion scanning explosive detector-It uses the difference in the rate of ion drift of various substances to identify substances. The detection sensitivity for drugs is 10E-9g, and the detection sensitivity for explosives is 10E-12g. 4. Neutron Detector 1. This is a new type of safety inspection equipment specially used to detect explosives, especially plastic explosives. Since neutrons are not shielded by metal or even heavy metal lead, they can penetrate all enveloping layers. And all explosives contain high levels of nitrogen. The neutron beam emitted by the neutron source hits the checked luggage. When it encounters the explosive, the nitrogen in the explosive will absorb the neutron and immediately release "gamma rays". By observing and recording gamma rays, explosives and plastic explosives can be detected. 5. X-ray inspection apparatus-An X-ray safety inspection system uses X-rays to see through an object, and distinguishes the object by seeing the image of the X-ray formed by the monitor. The dual-view X-ray security inspection device uses two bottom-ray and side-ray X-ray sources, which can simultaneously provide X-ray perspective images of luggage items in two directions, thereby avoiding the problem of unclear views due to a single perspective direction. Improved inspection reliability. At the same time, there are different new models of multi-energy X-ray safety inspection equipment, dual-channel multi-energy X-ray safety inspection equipment, and large exit angle X-ray safety inspection equipment. 6. CTX-5000 and CTX-5500 intelligent luggage scanners The baggage scanner uses medical CT technology, which can display the objects in the baggage from several angles. It combines the images displayed on different sides to form cross-sectional images, and analyzes them to determine whether there are explosives. Its performance surpasses similar X-ray machines.

The detection devices used in the present invention are all mature products. At present, there are many manufacturers providing this instrument, and special installation dimensions and structural forms can be customized according to the special requirements of users. Therefore, the implementation of the safety detection boarding bridge is simple and easy. Not only is it easy to install on the boarding bridge products in the factory, but more importantly, it can also be conveniently installed on the boarding bridge equipment currently in use at the existing airport.

The invention solves the problem that the metal articles carried by passengers and dangerous goods in parcels and luggage can be finally checked, that is, in addition to the security checkpoint of the departure hall, a security checkpoint is added on the boarding bridge passage, so that The missed detection rate was further reduced, the hidden dangers of aircraft flight safety were minimized, and the safety of civil aviation flight was further guaranteed.

The safety detection boarding bridge of the present invention can be applied to any airport, and the provided safety detection device can be installed on any type of passenger boarding bridge bridge, including glass side boarding bridges and steel structure side boarding bridges. Bridges, telescopic movable boarding bridges, T-type boarding bridges, etc. can also be installed on boarding bridges at passenger terminals, with a wide range of applications.
