Description
The application relates to a Chinese patent application (application day: 2021, 03, 30, and the title of the application: a multi-cabin door structure for a multifunctional vehicle-mounted security inspection system and a multifunctional vehicle-mounted security inspection system) with application number 202110344091.0.
Technical Field
The present disclosure relates to a multi-functional on-vehicle security inspection system, and a multi-hatch structure for a hatch body of the multi-functional on-vehicle security inspection system.
Background
The conventional security inspection object machine can only obtain a transmission two-dimensional image of an inspected object, and due to the overlapping of various substances in the case, drugs/explosives mixed in different substances are accurately detected, and particularly, it is very difficult to identify drugs/explosives from organic substances. In addition, the traditional security inspection object machine can only obtain perspective images along the ray direction, imaging of the same object at different placement angles can be different, and contraband is easy to ignore by a diagraph when placed at a specific angle. For the above reasons, while the conventional security inspection object machine is used for inspection, the unpacking inspection is still needed, including random spot inspection of the baggage and the package which are not suspected in a certain proportion, which brings about a small pressure to inspection. In addition, the real state of the interior of the object cannot be reflected on the perspective two-dimensional image, and if an interlayer condition exists, destructive disassembly of the object is required, and the condition also brings risks to inspection work. The vehicle-mounted article machine security inspection system developed based on the traditional security inspection article machine also has the defects. Most of the existing mobile security detection devices are single detection devices, namely only article security detection devices or only human body security detection devices.
In the security inspection industry, at present, a single vehicle-mounted article security inspection system and a single vehicle-mounted human body security inspection system have mature products, but the configuration of two types of equipment is not convenient. Therefore, the vehicle-mounted device can comprehensively check human bodies, articles and the like, and the checking content contains various contraband articles such as explosives, drugs and the like, and has wide application prospect. The design of the vehicle-mounted equipment is required to conform to various ergonomics, and is convenient for checking the checked person and the checked object.

The CT (computed tomography) security inspection technology is a high-tech security inspection technology developed in recent years. CT technology was originally applied in the medical field, and later extended to industrial nondestructive inspection and security inspection. The CT security inspection technology can acquire and utilize the measured object density, effective atomic number and other multidimensional information to realize detection and alarm of various drugs/explosives in the luggage, and has higher detection capability and lower false alarm rate; the CT security inspection system can well make up the defects of the traditional article machine in application.
In the present disclosure, a multi-functional on-board security system is provided. The truck chassis is used as a carrier of the multifunctional vehicle-mounted security inspection system, and excellent carrying capacity and good passing performance of the truck are utilized to configure equipment. A cabin 15 is arranged behind the truck chassis cab and divides the cabin 15 into a front portion and a rear portion, the front portion being an operating room 16 and the rear portion being an equipment room 17.
The present disclosure uses a moving vehicle as a carrier and advanced CT security equipment as a primary article detection means. The multifunctional vehicle-mounted security inspection system of the present disclosure includes: a cab 1; an operating room inlet 2; a millimeter wave human body detection device detection platform 3; a millimeter wave human body detection device 4; an X-ray fluoroscopic human body detection device 5; an X-ray fluoroscopic human body detection device inlet 6; an outlet conveying mechanism 7 of the CT article detection equipment; a CT article detecting apparatus 8; an inlet conveying mechanism 9 of the CT article detection equipment; a radioactive material detection apparatus 10; an operator station 11; a backscatter detection device 12; trace explosive drug safety inspection device 13; and a raman detector 14. The multifunctional vehicle-mounted security inspection system has the characteristics of flexibility and quick response, can be widely applied to important places such as airports, stations, ports, frontier defense investigation, major activities and the like, can meet the special requirements of special industry departments such as public security, civil aviation, customs and the like on the mobility of inspection places, and particularly aims at the situation that the inspected objects are widely distributed but have low density or emergency.
The equipment room 17 is provided with: a CT article detection device 8, an X-ray perspective human body security inspection device 5 and a radioactive substance detection device 10. The CT article detection device is transversely arranged at the rear part of the cabin 15. The radioactive substance detection device 10 is arranged on the left side in front of the CT article detection device 8, the X-ray perspective human body security inspection device 5 is arranged on the right side in front of the CT article detection device 8, and the X-ray perspective human body detection device inlet 6 is also arranged on the X-ray perspective human body device, so that the people to be detected can conveniently go in and out. The operation room 16 is provided with 1-2 stations and corresponding operation tables, and can control each device. The operator's compartment is provided with a separate 2 operator's compartment inlet through which an operator can enter. The back scattering detection device 12, the trace explosive safety inspection device 13, the Raman detector 14 and other detection instruments are arranged in the operation room, so that the operation room is convenient for operators to use. The millimeter wave human body security inspection device 4 is arranged outside the operation room 16 and is provided with the millimeter wave human body detection device detection platform 3, so that the detected personnel can conveniently complete detection outside the cabin 15. The layout of the respective devices in the device chamber 17 and the operation chamber 16 described above is merely exemplary, and other layouts may be included.
The function and effect of each device will be briefly described below. The X-ray perspective human body security inspection device 5 can judge whether dangerous goods and contraband are carried in the body of the person to be inspected by analyzing the scanning image, and can be mainly used for finding out drugs hidden in the abdomen of the human body. The millimeter wave human body security inspection device 4 can generate millimeter wave holographic images for inspected personnel by utilizing an active millimeter wave holographic imaging technology, and can determine whether suspicious articles are hidden on the surface of a human body or not from the images. The backscatter detection device 12 employs a non-contact security inspection technique that inspects in an image, and can quickly and accurately detect potential threats behind non-metallic surfaces. The radioactive substance detection apparatus 10 implements a monitoring system that judges whether or not the region to be detected contains a radioactive substance, by utilizing the principle that the leakage radiation of the radioactive substance will cause an abnormal change in the system count rate as it passes through the system monitoring channel. The trace explosive drug safety inspection device 13 can judge the kind of the detection substance by detecting the peak time of the weak current from the detector and matching it with the standard substance library. The raman detector 14 irradiates a substance to be detected with laser light, detects a raman spectrum of the substance to be detected, and recognizes the substance to be detected by comparing with a spectrum in a spectrum library.
The above advanced security inspection devices are very effective detection means in the respective detection fields, and each device has unique characteristics and a certain application range. If comprehensive security detection is desired, all devices need to be equipped individually. It should be noted that the multifunctional vehicle-mounted security inspection system does not necessarily include the above-mentioned various security inspection devices, some or all of the security inspection devices may be selected according to needs, and other security inspection devices known in the art may be applied to the multifunctional vehicle-mounted security inspection system.
In security inspection, an exemplary operational flow is as follows: the detected person sequentially goes back along the car body from front to back from the left side of the car head, and can complete the implementation monitoring of the radioactive substance without stopping when passing through the radioactive substance detection equipment 10; continuing to move forward, after the inspected person places the object on the entrance conveying mechanism 9 of the CT object detection equipment 8, the object moves from the left tail to the right tail, and at the moment, the object is completely detected and returned into the inspected person by the exit conveyor 7 of the CT object detection equipment; then the person to be detected moves forward along the right side of the vehicle tail, and enters the X-ray perspective human body detection equipment 5 for detection by the boarding ladder at the entrance 6 of the X-ray perspective human body security inspection equipment, namely the person to be detected needs to walk into the cabin 15; after detection, the human body detection platform continues to move forward, and the human body detection platform 3 stands for detection, namely, a detected person does not need to walk into the cabin 15; after detection, at the operation room entrance 2, the suspected substance is sampled by an operator, and the sample is brought into the operation room 16, and passes through trace explosive drug safety inspection equipment 13, a Raman detector 14 and other detection equipment; after detection, the vehicle head can leave from the front of the right side of the vehicle head if all the vehicle head passes through the vehicle head. The above security flow examples are merely exemplary, and the security flow may also vary according to the variation of the location of each security device. In the embodiment shown in fig. 3, the CT article detecting apparatus 8 adopts a single-side article in-out mode, and in the flowchart shown in fig. 3, the person to be inspected can complete all security inspection processes on a single side of the vehicle.
The vehicle-mounted mobile security inspection device is rapid in movement and convenient to unfold. After receiving the security inspection instruction, the system can quickly reach the designated security inspection place, quickly expand and start security inspection work. The security inspection equipment is not required to be taken off for installation and debugging, and can directly detect articles.
The vehicle-mounted security inspection equipment adopts the truck chassis as a carrier, so that the ground clearance is higher; the security personnel who is not suitable for holding the luggage carry out the article security action. Access Li Baoguo is inconvenient. Therefore, the sinking type design of the integral security inspection equipment is adopted.
Fig. 4 is a schematic illustration of a truck as a carrier for an in-vehicle security system prior to being untreated, in accordance with one embodiment of the present disclosure. As shown in fig. 4, the truck frame 20 is divided into a first portion 21 generally forward of the rear wheels and a second portion 22 generally rearward of the rear wheels. To install an in-vehicle security system according to the present disclosure, the second portion 22 of the truck boom 20 is truncated, as indicated by the shape "X" in FIG. 4.
Fig. 5 is a schematic view of a secondary support 30 according to one embodiment of the present disclosure. The secondary bracket 30 is mechanically secured to the truck frame where the second portion 22 has been cut, and a schematic view of the assembly of the secondary bracket 30 to the truck is shown in fig. 6.
In the embodiment shown in fig. 5, the sub-mount 30 is a section steel welded. The sub-mount 30 includes: a front frame 31, a middle connection 32 and a rear frame 33. The front frame 31 and the rear frame 33 are mechanically connected to or integrally formed with the middle connecting portion 32. The front frame 31 comprises at least two parallel frame strips 311 extending in the longitudinal direction perpendicular to the middle connection 32, preferably two parallel frame strips 311. In order to increase the rigidity of the front frame 31, a plurality of reinforcing cross bars 312 extending laterally are provided between the frame bars 311 extending in parallel. As shown in fig. 9, in order to facilitate the passage of the cable or the like through the sub-mount 30, a plurality of threading holes 313 are provided in the sub-mount, and the threading holes 313 may be provided in the reinforcing cross bar 312 or in the frame strip 311. At one end of the frame strip 311 remote from the middle connection portion 32, a cantilever 314 protruding toward both sides in the lateral direction is provided, and the lateral width of the cantilever 314 is larger than the lateral span of the plurality of frame strips 311. The cantilever 314 is used to support the hull 15. The lateral width of the middle connection portion 32 is also greater than the lateral span of the plurality of frame bars 311 and corresponds to the width of the cantilever arms 314.
The rear frame 33 includes two frame bars 331 extending from both lateral ends of the middle connecting portion 32. Each frame strip 331 includes a first portion 3311 and a second portion 3312 that form a generally L-shape. The first portion 3311 extends vertically downward from the lateral end portion thereof perpendicularly to the middle connecting portion 32, and the vertical extending height of the first portion 3311 is designed such that the ground clearance height thereof is suitable for the height of the luggage placed by the person to be inspected. The second portion 3312 extends rearward in the longitudinal direction from a vertical lower end of the first portion 3311. A hollow structure is arranged between the two frame strips 331. At the front and rear end positions of the two frame bars 331, a reinforcing rib 332 is provided between the two frame bars 331 extending in parallel. Optionally, a via hole is also provided on the rear frame 33. Therefore, the rear frame 33 has a sinking structure, a hollow structure in the middle, a space for the CT object detecting device 8, and a reinforcing rib connection in part, so that the whole sub-bracket 30 has a special-shaped structure
The rear frame 33 is configured to carry the CT article detection apparatus 8, and schematic diagrams of the rear frame 33 carrying the CT article detection apparatus 8 are shown in fig. 7A (side view) and fig. 7B (top view). As can be seen in fig. 8, the rear of the nacelle is submerged. The inspected article may be fed into the CT article detection apparatus 8 through the door as shown in fig. 8 to be inspected.
In the vehicle-mounted security inspection system of the present disclosure, since the X-ray inspection is to be protected, similar to the X-ray irradiation, the outside of the irradiation area is to be protected, so that the inspection person is required to enter the vehicle, and can enter the cabin 15 through the X-ray transparent human body security inspection device entrance 6 to perform the inspection in the X-ray transparent human body inspection device 5. The millimeter wave human body detection device 4 is completely harmless, does not need to be protected, and can be directly arranged outside a vehicle, and a person to be detected can stand on the millimeter wave human body detection device detection platform 3 to finish the test.
The three doors associated with the millimeter wave human body detection device detection platform 3 will be described below.
Since the millimeter wave human body detection device 4 is higher than the inside of the cabin 15, the millimeter wave human body detection device 4 cannot be directly installed in the cabin 15. The millimeter wave human body detection equipment 4 is arranged close to the outer wall of the cabin body 15, the outer wall is designed as a three-open cabin door, the left and right open cabin doors 41 and 42 can well shield interference, handrails can be stretched out, and the downward-turned lower cabin door 43 can support the millimeter wave standing detection platform 3. The lower door 43 requires the installation of a booster pneumatic spring 50 as an auxiliary support due to its large gravity, which reduces effort when the worker turns the door.

In the present disclosure, the millimeter wave standing detection platform 3 and the lower hatch door 43 are pivotable between a folded state as shown in fig. 14 in which the millimeter wave standing detection platform 3 and the lower hatch door 43 are close to each other, and an unfolded state as shown in fig. 13 in which the millimeter wave standing detection platform 3 and the lower hatch door 43 are apart from each other in the vertical direction and both are unfolded to be parallel to the horizontal direction.
As an example, in the folded state, the lower hatch 43 and the standing detection platform 3 may be placed in a vertical direction and spaced apart a first distance in a horizontal direction, and said lower hatch 43 is flush with the cabin outer wall;
in the unfolded state, the lower cabin door 43 and the standing detection platform 3 are placed in the horizontal direction, are separated in the vertical direction by a second distance and are perpendicular to the outer wall of the cabin body, and the second distance is larger than the first distance;
in the course of going from the folded state to the unfolded state, lower hatch 43 and standing inspection platform 3 are gradually distanced from each other, said standing inspection platform 3 being configured for the person to be inspected to stand on in the unfolded state.
The door opening generally performs the following procedure: when the mobile security inspection vehicle arrives at a designated working place, the left cabin door 41 and the right cabin door 42 are opened firstly, the opening angle and the bulkhead form a right angle of 90 degrees, and the structure well shields the interference objects outside the vehicle; then the millimeter wave lower cabin door 43 is opened and parallel to the ground, and the standing detection platform 3 which can be turned out after being unfolded in place can be used as a standing platform for security personnel to conduct personnel security inspection operation.
The door closing generally performs the following procedure: when the security inspection operation is completed, the lower cabin door 43 is first retracted, and then the left and right doors 41 and 42 are closed. The auxiliary gas spring 50 plays an auxiliary supporting role, so that the side cabin can be conveniently retracted by operators.
An auxiliary gas spring 50 and a bracket mechanism are arranged between the millimeter wave standing detection platform 3 and the lower cabin door 43. The auxiliary gas spring 50 has one end connected to one of the millimeter wave standing detection platform 3 and the lower cabin door 43 and the other end connected to the other of the millimeter wave standing detection platform 3 and the lower cabin door 43. Specifically, one end of the auxiliary gas spring 50 is connected to a member whose position remains unchanged during the lifting and tilting-down of the lower door 43. For example, a standing inspection platform pivot axis 3a and a lower hatch door pivot axis 43a. During this movement, their position does not change since they are connected to the cabin frame. One end of the auxiliary gas spring 50 may be connected to the pivot shaft of one of the standing inspection platform and the lower door 43, while the other end is connected to the other of the lower door 43 and the standing inspection platform 3.
In the embodiment shown in fig. 13, standing inspection platform 3 comprises three rims, a first rim 34 and a second rim 35 being perpendicular to pivot axis 3a, and a third rim 36 being parallel to pivot axis 3a. The lower door 43 includes four rims, a first rim 431 and a second rim 432 extending perpendicular to the pivot axis 43a, respectively, a third rim 433 connected to the first rim 431 and the second rim 432 at both ends thereof and spaced apart from the pivot axis 43a in parallel to the pivot axis 43a, and a fourth rim 434 extending along the axis of the lower door pivot axis 43a, the fourth rim 434 being parallel and opposite to the third rim 433. Although in the illustrated embodiment, standing inspection platform 3 includes three rims, it may also include four rims similar to lower door 43. Although in the illustrated embodiment lower door pivot axis 43a and standing inspection platform pivot axis 3a are mounted on the outside of the frame, standing inspection platform pivot axis 3a may extend through first and second rims 34 and 35 of standing inspection platform 3. The lower door pivot shaft 43a may also extend through the first frame 431 and the second frame 432 without providing the fourth frame 434.
In the embodiment shown in fig. 13, the rod end of the auxiliary gas spring 50 is pivotally connected to the fourth frame 434 of the lower door 43, and the base end of the auxiliary gas spring 50 is pivotally connected to the lower surface of the standing inspection platform 3. In another embodiment, the base end of the auxiliary gas spring 50 is pivotally connected to the fourth frame 434 of the lower door 43, and the rod end of the auxiliary gas spring 50 is pivotally connected to the lower surface of the standing inspection platform 3. Since the position of the pivot shaft 43a does not change during the entire door movement, the position of the fourth frame 434 may also be regarded as unchanged, the rod end of the auxiliary gas spring 50 may be regarded as a fixed point, and the base end connected to the lower surface of the standing inspection platform 3 changes position with the downward and upward movement of the lower door 43, so that the standing inspection platform 3 is far from and near to the lower door 43. The difference between the center distances of the two extreme positions of the base end is the stroke of the gas spring.
However, although in the illustrated embodiment, the rod end of the auxiliary gas spring 50 is pivotably connected to the fourth frame 434 of the lower door 43, the present application is not limited thereto, and the base end of the auxiliary gas spring 50 may be pivotably connected to the fourth frame 434 of the lower door 43. In the present disclosure, as long as one of the rod end and the base end of the auxiliary gas spring 50 is kept unchanged in position during movement of the lower door and the other end can be changed in position. Since neither the position of the standing inspection platform pivot axis 3a nor the lower door pivot axis 43a changes, one of the rod end and the base end of the auxiliary gas spring 50 may also be pivotally connected to the standing inspection platform pivot axis 3a, the other of the rod end and the base end being connected to the inner surface of the lower door 43.
The bracket mechanism includes a first bracket 51 and a second bracket 52, both ends of the first bracket 51 are pivotally connected to the first frame 431 of the lower door 43 and the first frame 34 of the standing detection platform 3, respectively, and both ends of the second bracket 52 are also connected to the first frame 431 of the lower door 43 and the first frame 34 of the standing detection platform 3, respectively, so that the first frame 431 of the lower door 43 and the first frame 34 of the standing detection platform 3 and the second bracket 52 constitute a parallelogram-like mechanism. As an example, the first frame 431 of the lower door 43 may be hinged with the lower door pivot axis 43a and the second bracket 52, respectively, and the first frame 34 of the standing inspection platform 3 may be hinged with the standing inspection platform pivot axis 3a and the second bracket 52, respectively. As shown in fig. 13, the hinge point of the first frame 431 of the lower door 43 and the lower door pivot axis 43a is a, the hinge point of the first frame 431 of the lower door 43 and the second bracket 52 is B, the hinge point of the first frame 34 of the standing detection platform 3 and the second bracket 52 is C, and the hinge point of the first frame 34 of the standing detection platform 3 and the standing detection platform pivot axis 3a is D. When the standing inspection platform 3 and the lower door 43 are switched from the unfolded state to the folded state, the first frame 431 of the lower door 43 rotates about the hinge point a (or about the lower door pivot axis 43 a) and the first frame 34 of the standing inspection platform 3 rotates about the hinge point D (or about the standing inspection platform pivot axis 3 a). When the first frame 431 of the lower door 43 and the first frame 34 of the standing detection platform 3 are rotated to the position shown in fig. 14, the standing detection platform 3 and the lower door 43 are in a folded state. The first bracket 51 and the second bracket 52 may provide a constraint for the rotation of the first frame 431 of the lower door 43 and the first frame 34 of the standing detection platform 3, may make the rotation of the first frame 431 of the lower door 43 and the first frame 34 of the standing detection platform 3 more stable, and may be able to follow a predetermined trajectory to avoid unnecessary mechanical interference.
In the present disclosure, preferably, two auxiliary gas springs 50 and two bracket structures are included. The other auxiliary gas spring 50 and the aforementioned auxiliary gas spring 50 are disposed in parallel with each other. Both ends of the other bracket mechanism are pivotally connected with the second frame 432 of the lower cabin door 43 and the second frame 35 of the standing detection platform 3, respectively.
The first bracket 51 is formed of a first portion 511 and a second portion 512, the first portion 511 and 512 being hinged together at a central portion of the first bracket 51 such that the first and second portions are rotatable relative to each other such that the relative positions of the first and second portions are different in the unfolded state and the folded state. The hinge end face 5111 of the first portion 511 and the hinge end face 5121 of the second portion are respectively formed obliquely so that the first portion 511 and the second portion 512 are not parallel to each other when the first bracket 51 is in the maximum unfolded state, and an angle therebetween is smaller than 180 °, for example, an angle between 150 ° and 170 °, as shown in fig. 13, in order to avoid occurrence of dead spots, thereby preventing the first portion 511 and the second portion 512 from being rotated in opposite directions. As shown in fig. 14, in the folded state, the first portion 511 and the second portion 512 are pivoted to be stacked together.
In the illustrated embodiment, the rod end of the auxiliary gas spring 50 is pivotally connected to the fourth frame 434 of the lower door 43, and the auxiliary gas spring 50 can assist in lifting the lower door upward, thereby reducing the burden on the worker. The above-described bracket mechanisms 51 and 52 abut each other through the end surfaces 5111 and 5121 in the deployed state, and rigidly support the standing inspection platform 3 such that the standing inspection platform 3 is away from the lower hatch door 43. The above-described bracket mechanisms 51 and 52 bring the standing inspection platform 3 close to the lower hatch door 43 by being stacked together in the folded state.
Although described in the above embodiments as an example of three doors, embodiments of the present disclosure are not limited thereto, and for example, a multi-door structure for a multifunctional in-vehicle security inspection system may include other numbers of doors, such as two, four, or more, etc.
The embodiment of the disclosure also provides a multifunctional vehicle-mounted security inspection system, which comprises the multi-cabin door structure according to any one of the embodiments.
