Description

The present invention relates to a technique of a baggage inspection device and a baggage inspection system for performing efficient baggage inspection.

In recent years, the threat of terrorism has increased worldwide. Explosives, in particular, are increasingly being used in recent terrorism as powerful explosives manufacturing methods made from daily necessities have spread via the Internet. One of the effective means for preventing such explosive terrorism is to find an explosive hidden in a bag or the like with an explosives detector. One of the explosives detection methods is bulk detection, which finds a mass of explosives using X-rays or the like. In addition, trace detection, in which fine particles adhering to a bag or the like are skipped by an air flow or the like and traces of a trace amount of explosive are found from the fine particles, is also one of the explosives detection methods. Since the information obtained by bulk detection and trace detection is different and can be operated in a complementary manner, security can be improved by using both detection methods together.

Japanese Unexamined Patent Publication No. 2006-58318 Japanese Patent No. 5690840

Explosives detection devices are effective as counterterrorism measures, but they are used only in limited places such as airports. Low throughput is one of the reasons why explosives detectors are not widespread. In other words, it takes time for inspection, so it is difficult to operate in places where a large number of people come and go, such as stations, buildings, commercial facilities, and stadiums. Among the explosives detection, for trace detection, a high-throughput inspection system as shown in Patent Document 2 is disclosed. Therefore, it is desired to develop a high-throughput inspection system by bulk detection.

The present invention has been made in view of such a background, and an object of the present invention is to perform an efficient baggage inspection.

In order to solve the above-mentioned problems, the present invention has a first lane in which luggage moves and a second lane in which people move, and the first lane has a moving floor surface. The second moving lane has a second moving part having a moving floor surface, and has the first moving part and an inspection part for inspecting the baggage. The second moving portion and the second moving portion move while maintaining the same height as each other, and the first moving portion moves at a speed corresponding to the moving speed of the second moving portion.
Other solutions will be described as appropriate in the embodiments.

Next, an embodiment (referred to as “embodiment”) for carrying out the present invention will be described in detail with reference to the drawings as appropriate.

[First Embodiment]
FIG. 1 is a diagram showing a configuration of a cargo inspection system Z according to the first embodiment.
The cargo inspection system Z has a cargo inspection device 1 and a processing device (processing unit) 2.
The cargo inspection device 1 shown in FIG. 1 is an image of a so-called moving walkway, which travels on a movable floor board in a place without steps.
When the person P brings the luggage B, the person P places the luggage B on the luggage floor plate (first moving portion) 125 of the luggage lane (first lane) L2. Then, the person P stands in the person lane (second lane) L1 composed of the person floor plate (second moving portion) 111 and the handrail 112. These human for floor 111, speed belt portion of the luggage floor panel 125 and handrail 112 corresponding to the same direction, in this example are moving at the same speed. The person P and the baggage B are not elements constituting the baggage inspection device 1.
By doing so, the person P moves in the person lane L1 and the luggage B moves in the luggage lane L2. Further, in this example, the person P and the luggage B translate at the same speed.

An X-ray imaging device (inspection unit, X-ray inspection unit) XR is provided at a predetermined position in the luggage lane (first lane) L2. In the X-ray photographing apparatus XR, the X-ray irradiating apparatus 121 and the X-ray receiving apparatus 122 are arranged so as to face each other so as to sandwich the luggage lane L2. When the luggage B passes between the X-ray irradiating device 121 and the X-ray receiving device 122, the X-ray irradiating device 121 irradiates the X-ray R. Then, the X-ray R transmitted through the baggage B is detected by the X-ray receiver 122. The signal generated as a result of being detected by the X-ray receiver 122 is sent to the processing device 2 via the signal line 3. The processing device 2 obtains information on the transmission image of the baggage B by performing signal processing.

In order to avoid exposure to the person P by the X-ray R, a partition wall 124 for shielding the X-ray R is provided between the person lane (second lane) L1 and the luggage lane L2. A part of the partition wall 124 is provided with lead glass (visible portion) 123 that transmits visible light and shields X-ray R so as not to obstruct the line of sight E of the person P. By doing so, the person P can visually recognize his / her luggage B. As a result, the person P does not have to worry about the loss of the luggage B. Further, it is possible to prevent the person P from mistakenly mistaken the baggage B for another person's baggage B or misplaced the baggage B when getting off the person lane L1.

If the baggage inspection device 1 is installed close to the wall W as shown in FIG. 1, the X-ray R is shielded by the wall W. Therefore, it is necessary to newly provide a partition wall at the position of the wall W in FIG. There is no. By doing so, it is possible to reduce the cost. In this case, it is desirable that the wall W has a thickness that does not allow the X-ray R to pass through, or is made of a material that does not easily transmit the X-ray R.
Further, as shown in FIG. 1, when the partition wall on the side other than the human lane L1 side is replaced by the wall W, the X-ray light receiving device 122 may be attached to or embedded in the wall W. Of course, the wall W may be used as a partition wall, and the X-ray receiving device 122 may be installed on this partition wall.
Further, in order to prevent the person P from being exposed to the X-ray R leaked from above the luggage lane L2, it is desirable that the ceiling 126 is installed at least in the vicinity where the X-ray photographing apparatus XR is provided.

FIG. 2 is a top view of the cargo inspection device 1 according to the first embodiment. In FIG. 2, the same components as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. Also, refer to FIG. 1 as appropriate.
Here, it is assumed that the person P holding the luggage B heads from the entrance F1 to the exit F2 (white arrow). Of course, the belts of the floor board 111 for humans, the floor board 125 for luggage, and the handrail 112 flow from the inlet F1 to the exit F2.

As shown in FIG. 2, an inlet gate 130 is provided on the side of the inlet F1 and an outlet gate 170 is provided on the side of the outlet F2. As shown in FIG. 2, the partition wall 124 does not need to be provided at all from the inlet F1 to the outlet F2. Since the X-ray R irradiated by the X-ray irradiation device 121 is attenuated by the square of the distance from the X-ray irradiation device 121, the partition wall is set to a distance such that the leakage of the X-ray R is attenuated to a level that does not affect the human body. 124 may be provided.
As for the range in which the ceiling 126 is provided, the ceiling 126 may be provided in a range shielded by the partition wall 124.

The baggage inspection device 1 is adapted to run side by side for a while after the person P and the baggage B pass through the partition wall 124. By providing such a parallel running portion, it is possible to provide a pickup area A1 for the person P to confirm and pick up his / her luggage B. By doing so, the person P can get off the floor board 111 for the person at the exit F2 together with the luggage B with a margin. As a result, the flow of the person P becomes smooth.

When the partition wall 124 has a width and the floor plate 111 for humans and the floor plate 125 for luggage are separated from each other, the space between the floor plate 111 for humans and the floor plate 125 for luggage may be narrowed in the pickup area A1. In FIG. 2, as an example, the cargo floor plate 125 is configured to move toward the human floor plate 111 after passing through the partition wall 124.
In the example shown in FIG. 2, since the partition wall 124 has a thickness, the luggage floor plate 125 is configured to be closer to the human floor plate 111, but the present invention is not limited to this. If the thickness of the partition wall 124 can be reduced, the luggage floor plate 125 may be configured to proceed straight from the inlet F1 to the outlet F2.

Further, as shown in FIG. 2, a baggage sensor (baggage passage detection unit) 127 is provided near the entrance F1 side of the X-ray irradiation device 121. The luggage sensor 127 is an infrared sensor or the like. When the passage of the baggage B is detected by the baggage sensor 127, the processing device 2 causes the X-ray irradiation device 121 to irradiate the X-ray irradiation device 121 with X-rays R. By doing so, the X-ray R can be irradiated only when the baggage B passes through, so that an energy saving effect can be realized.
Further, since the irradiation of X-ray R can be minimized, the leakage to the person P and the influence of exposure can be minimized.

Further, as shown in FIG. 2, an infrared camera (biological detection unit) 128 is provided near the entrance F1 side of the luggage sensor 127. When the processing device 2 analyzes the image of the infrared camera 128 and detects a heat source of a predetermined size, it determines that a person P, a pet, or the like is on the luggage floor plate 125, and stops the irradiation of X-ray R. do. By doing so, it is possible to prevent a person P (particularly a child or the like) or a pet or the like from being accidentally exposed to radiation.
In addition, a commonly used camera may be used instead of or together with the infrared camera 128 of FIG. In this case, the processing device 2 determines whether or not the person P, the pet, or the like is on the cargo floor plate 125 by image analysis or the like.

The entrance gate 130 and the exit gate 170 will be described later.

FIG. 3 is a schematic view of the cargo inspection device 1 according to the first embodiment as viewed from the direction of the entrance F1. In FIG. 3, the same components as those in FIGS. 1 and 2 are designated by the same reference numerals, and the description thereof will be omitted.
As shown in FIG. 3, an entrance gate 130 is provided at the entrance F1. A display board 131 is installed at the entrance gate 130. On the display board 131, the distinction between the human lane L1 and the luggage lane L2 is clearly indicated. By doing so, it is possible to call attention so that the person P does not enter the luggage lane L2. By the way, the alert may be given by being guided by voice.

Then, a surveillance camera (entrance photographing unit) 132 provided at the entrance gate 130 takes a picture of the person P placing the luggage B on the luggage floor plate 125 in the luggage storage area A2. The processing device 2 associates the person P with the luggage B based on the image taken by the surveillance camera 132. Such a linking process will be described later.

Further, the processing device 2 determines whether or not the person P accidentally got on the cargo floor plate 125 based on the image taken by the surveillance camera 132. Then, when the processing device 2 determines that the person P is erroneously riding on the luggage floor plate 125, the processing device 2 stops driving the belt portions of the human floor plate 111, the luggage floor plate 125, and the handrail 112. Then, the processing device 2 stops the irradiation of the X-ray R by the X-ray irradiation device 121 (see FIGS. 1 and 2). Further, the processing device 2 issues an alarm from the alarm device (alarm unit) 133 to give a warning to the person P who got on by mistake and urge him to leave. By providing the surveillance camera 132 in this way, the safety aspect can be improved.

Further, by analyzing the image of the surveillance camera 132, the processing device 2 determines the size of the luggage B mounted on the luggage floor plate 125, the surface material of the luggage B, the placement direction of the luggage B, and the like. Then, the processing device 2 obtains the output and direction of the X-ray R for photographing the cargo B, if necessary, based on the information such as the size of the cargo B, the surface material of the cargo B, and the loading direction of the cargo B. May be adjusted.

Further, as shown in FIG. 2, an outlet gate 170 is also provided on the outlet F2 side.

As shown in FIG. 4, the exit gate 170 has a surveillance camera (exit photographing unit) 172 and an alarm device (alarm unit) 173.
As described above, the image of the person P and the image of the luggage B are linked from the image of the surveillance camera 132 provided at the entrance gate 130 shown in FIG. Based on the linked information and the image of the surveillance camera 172 of the exit gate 170, the processing device 2 causes the person P to carry the wrong baggage B (mistake) or try to leave without carrying the baggage B (mistake). Determine if it is misplaced). Then, when the processing device 2 detects a mistake or misplacement, the processing device 2 issues an alarm from the alarm device 173 provided at the exit gate 170. By doing so, it is possible to prevent the baggage B from being mistaken or misplaced. The processing to prevent mistakes and misplacement will be described later.

(Cargo step 140)
FIG. 12 is a diagram showing a first configuration example of the cargo step 140.
The cargo step 140a (140) shown in FIG. 12 is configured by fixing the step plate 141 and the riser 142 to the frame 143.
Here, in the escalator type cargo inspection device 1d as shown in FIG. 11, it is advisable to take measures to prevent the cargo B from falling from the cargo step 140a as it moves.
Therefore, in the cargo step 140a shown in FIG. 12, a slide plate (fall prevention portion) 144 is provided on the step plate 141. Then, when the large luggage B is placed on the luggage step 140a, the slide plate 144 is pulled out (arrow in FIG. 12). By doing so, the large luggage B is supported by the slide plate 144, and the luggage B can be prevented from falling (arrow in FIG. 12).

The drawer of the slide plate 144 may be realized, for example, by providing a weight sensor (not shown) in the vicinity of the riser 142 of the tread plate 141. That is, when the weight sensor detects the weight, it is detected that the luggage B may be larger than the tread plate 141, and the processing device 2 pulls out the slide plate 144. Then, when the cargo step 140a passes near the exit gate 170 and returns to the entrance F1 side, the processing device 2 stores the slide plate 144.

FIG. 13 is a diagram showing a second configuration example of the cargo step 140.
In the luggage steps 140b to 140d shown in FIGS. 13 to 15 below, the same components as those in FIG. 12 are designated by the same reference numerals, and the description thereof will be omitted.
In the cargo step 140b (140) shown in FIG. 13, a stopper (fall prevention portion) 146 is provided at the end of the tread 141 on the riser 142 side so that the cargo B does not fall. When the luggage B is placed on the tread 141, the stopper 146 is raised.
Specifically, for example, when the cargo step 140b starts to rise, the stopper 146 is raised.
The stopper 146 is pulled out and retracted in the vertical direction as shown by the arrow in FIG.
By providing such a stopper 146, it is possible to prevent the luggage B from falling.
Further, when the cargo step 140b is of a type that is folded when the luggage step 140 returns from the exit F2 side to the entrance F1 side, the stopper 146 may be stored by falling toward the broken line 146a side.

FIG. 14 is a diagram showing a third configuration example of the cargo step 140.
In the cargo step 140c (140) shown in FIG. 14, the tread 141 is provided with an inclination (fall prevention portion). By doing so, the luggage B is placed at an angle toward the luggage step 140c in the front stage and is supported by the luggage step 140c in the front stage. By doing so, it is possible to prevent the luggage B from falling.

FIG. 15 is a diagram showing a fourth configuration example of the cargo step 140.
In the cargo step 140d shown in FIG. 15, a tread 141d having an uneven portion (movement prevention portion) is provided. The uneven portion fixes the tire B1 to the luggage B with the tire B1 such as a suitcase so that the luggage B does not move. By doing so, it is possible to prevent the luggage B from moving, and it is possible to prevent the luggage B from falling.

The length of the tread plate and the height of the riser of the human step 150 used in the human lane L1 on which the escalator type person P is boarded are generally about 30 cm. Therefore, the length of the tread 141 used for the luggage lane L2 and the height of the riser 142 may be changed from those of the human lane L1. For example, at least one of the length of the tread plate 141 and the height of the riser 142 is installed at about 50 cm to 100 cm. By doing so, it is possible to prevent the person P from accidentally entering the cargo lane L2 because it is clearly different from the tread plate of a general escalator.
