Description
Technical Field
The utility model relates to a safety inspection equipment technical field especially relates to a hazardous articles automatic check out equipment.
Background
At present, in public transportation places such as railway stations, subway stations and the like, passerby security inspection is required to be carried out on passing passengers, firstly, the passerby forms an X-ray image through a security inspection machine, a security inspector identifies suspected explosives or drugs, and then a trace explosive/drug detector is used for rechecking. Although trace explosives/drugs detectors are equipped in the places, the detection of 100% explosives/drugs in the detected luggage is difficult, and the ratio of the luggage subjected to the explosives/drugs detection is low. In addition, the identification capability of the security inspector on the explosive/drug images in the X-ray images of the luggage is influenced by objective factors such as the skill level and the working state of the security inspector, and the individual difference of the security inspector has a great influence on the detection rate of the explosive/drug. So that although the detection equipment for explosives/drugs is provided, when the security inspector identifies the luggage X-ray image, the security inspector is easy to miss detection, and the explosives/drugs are not detected by the trace explosive/drug detector.
In addition, the labor cost for explosives/drugs detection is high. In the existing security inspection mode, a security inspector is required to identify images of a security inspection X-ray machine for primary security inspection, and other security inspectors can confirm whether suspicious bags contain explosives/drugs by using a trace explosive/drug detector for secondary inspection, so that the security inspector at a relevant post is required to be specially trained to be competent for detection of the explosives/drugs.
And the efficiency of explosive/drug detection and inspection is low. Because the security inspector uses the trace explosive/drug detector for secondary security inspection, the speed of the security inspector using the trace explosive/drug detector for secondary security inspection is lower than that of the security X-ray machine (the speed of the security inspector identifying one luggage for image inspection by the security X-ray machine is 5-10 seconds, the speed of the security inspector using the explosive/drug detector for image inspection by the luggage is 20-30 seconds), and when more than two luggage need of secondary security inspection by the security inspector using the trace explosive/drug detector occur continuously, the overall security inspection speed is greatly reduced, and the security inspection passing speed of passengers is seriously influenced.

Referring to the above-mentioned drawings, the automated hazardous material detecting apparatus 100 may generally include a first conveyor 111, a second conveyor 112, a hazardous material detector 130, and a guide mechanism 120. In addition, the automatic dangerous article detection equipment 100 of the embodiment further includes a casing 101, an inlet and an outlet are formed on two opposite sides of the casing 101, so that the article 105 to be detected can enter and leave the automatic dangerous article detection equipment 100, and the conveying direction of the article 105 to be detected is shown as an arrow direction.
The beginning of the conveying surface of the first conveyor belt 111 is used to receive the article 105 to be detected and is configured to convey the article 105 to be detected towards its end. The first conveyor belt 111 does not have to be the starting conveyor belt of the automated hazardous material detection apparatus 100, i.e., the starting end of the first conveyor belt 111 may be provided with other conveyor belts connected thereto.
The beginning of the conveying surface of the second conveyor belt 112 is spaced opposite the end of the conveying surface of the first conveyor belt 111 and is configured to receive and continue to convey the articles 105 to be detected conveyed by the first conveyor belt 111. The second conveyor belt 112 does not have to be an end conveyor belt of the automatic hazardous material detection device 100, i.e., the end of the second conveyor belt 112 may be provided with other conveyor belts connected thereto.
The number of the dangerous goods detectors 130 is one or more, each dangerous goods detector 130 has a sampling port 131, and the sampling port 131 is arranged at the interval between the first conveyor belt 111 and the second conveyor belt 112 and is used for detecting and sampling the goods 105 to be detected passing through the upper part of the sampling port. The hazardous article detector 130 generally has a large-sized main body portion, which may be disposed below the first and second conveyors 111 and 112. In particular, the hazardous article detector 130 which is structurally integrated but has a plurality of sampling ports 131, and each sampling port 131 is functionally independent from each other, i.e., can simultaneously detect a plurality of articles 105 to be detected, respectively, should be regarded as a plurality of hazardous article detectors 130.
Because the hazardous article detector 130 of the present invention usually selects an explosive detector and/or a drug detector to detect and sample hazardous articles, and the effective detection distance between the existing explosive detector and the drug detector is about 0 to 10 cm, the sampling port 131 should be set to be horizontal and as close as possible to the transmission surface of the first transmission belt 111; however, in order to reduce the contact between the hazardous article detector 130 and the article 105 to be detected and avoid the hazardous article detector 130 from being damaged due to frequent friction, the sampling port 131 is usually set to be 1 to 20 mm lower than the conveying surface of the first conveyor belt 111. The distance of sampling mouth 131 to the transmission face can be according to the effective detection distance of the hazardous articles detector 130 of selecting for use in practice, the nimble adjustment of the interval size between sampling mouth 131 length and first conveyer belt 111 and the second conveyer belt 112, and the universality can set up to 5 millimeters or 10 millimeters.
In addition, since the object 105 to be detected may be a satchel, a suitcase or other objects with various shapes and widths in actual use, in order to ensure that the object 105 to be detected completely passes through the sampling range of the sampling port 131 as far as possible, the dangerous goods detector 130 with the rectangular or approximately rectangular sampling port 131 should be selected, and the dangerous goods detector 130 with the total width of the sampling port 131 close to the width of the first conveyor belt 111 is preferably selected to ensure that the detection range of the sampling port 131 covers the width of the conveying surface as far as possible. The length of the sampling port 131 can be flexibly selected based on the existing hazardous article detector 130 on the basis of ensuring the detection sampling efficiency and the passing efficiency of the article 105 to be detected.
A guide mechanism 120 having two guide arms 121 located above the first conveyor belt 111; the two guide arms 121 are configured to guide the object 105 to be inspected to a transport direction facing the sampling port 131. In general, the guide arm 121 may be divided into a swing portion and a rotating shaft portion, wherein the swing portion may be cylindrical, elliptic cylindrical, or plate-shaped, and may have other shapes. The swinging portion of the guide arm 121 is used to push or block the object 105 to be inspected to adjust the object 105 to be inspected to a position facing the sampling port 131. Referring to fig. 2 and 3, the object 105 to be detected located at the position indicated by the dotted line is transferred to the guide arm 121 along with the first conveyor belt 111, is adjusted in position after being guided by the guide arm 121, and is transferred to the position indicated by the solid line along with the first conveyor belt 111.
It can be understood that the position of the object 105 to be detected opposite to the sampling port 131 is the position of the width of the object to be detected opposite to the center of the sampling port 131, i.e. the moving direction of the object 105 to be detected at the center point of the width of the object to be detected is opposite to the center of the sampling port 131. Similarly, the conveying direction of the object 105 to be detected is opposite to the sampling port 131, i.e. the moving direction of the object 105 to be detected at the center point of the width thereof is opposite to the center of the sampling port 131.
In some optional embodiments, referring to fig. 2, the number of the hazardous article detection instruments 130 is one, the sampling port 131 of the hazardous article detection instrument 130 is disposed at a position where the width center point of the hazardous article detection instrument 130 coincides with the center line of the conveying surface of the first conveyor belt 111, and the guide arm 121 guides the article 105 to be detected to the position where the width center point is located on the center line of the conveying surface of the first conveyor belt 111, so that the article 105 to be detected can be directly opposite to the sampling port 131.
In other alternative embodiments, referring to fig. 3, the number of the hazardous article detection apparatuses 130 is multiple, and the sampling ports 131 of the hazardous article detection apparatuses 130 are sequentially arranged in the width direction of the gap. Because the automatic hazardous article detection device 100 may need to continuously sample and detect a large number of articles 105 to be detected in practical application, while the conventional hazardous article detector 130 generally needs a certain time to analyze a detection sample, the automatic hazardous article detection device 100 provided with only one hazardous article detector 130 may not meet the requirements in terms of work efficiency, and thus, a plurality of hazardous article detectors 130 may be provided. The guide arm 121 can guide a plurality of continuous objects 105 to be detected to different sampling ports 131 in sequence, so that the automatic hazardous article detection device 100 can simultaneously perform detection sampling and sampling analysis on the plurality of objects 105 to be detected, and the detection sampling efficiency is effectively improved. According to the actual use requirement of the automatic hazardous material detection device 100, the number of the sampling ports 131 is usually two to four; in addition, the distance between the adjacent sampling ports 131 should be reduced as much as possible on the basis that the object 105 to be detected passing through one sampling port 131 does not affect the adjacent sampling ports 131.
In some alternative embodiments, the two guide arms 121 are rotatably disposed at two opposite sides of the first conveyor belt 111, and the rotation axis is perpendicular to the conveying plane of the first conveyor belt 111; the two guide arms 121 can swing above the first conveyor belt 111. The two guide arms 121 are identical in shape and configuration, but the two guide arms 121 do not need to swing at the same time, and the two guide arms 121 may be configured such that only one of the guide arms 121 swings, or the two guide arms 121 swing at the same time by different angles, respectively, and obviously, the two guide arms 121 may also swing at the same angle at the same time. In the operating state, the two guide arms 121 respectively swing between a position parallel to the transport direction of the first conveyor belt 111 and having ends pointing in the transport direction of the first conveyor belt 111 and a position having ends pointing in the other guide arm 121, but the two guide arms 121 may also swing at other angles.
In some optional embodiments, the automated hazardous material detection apparatus 100 further comprises a camera 140. The camera 140 is disposed above the second conveyor belt 112, and the monitoring area faces the first conveyor belt 111, for monitoring the article 105 to be detected conveyed on the first conveyor belt 111. In order to ensure the monitoring effect, the camera 140 is usually disposed on the inner side wall of the casing 101, and the position above the center line of the transmission surface of the second conveyor belt 112 near the top of the casing 101, and monitors the area of the first conveyor belt 111, so as to obtain the position and shape parameter information of the object 105 to be detected at any time. Usually, the automatic dangerous article detection equipment 100 is further provided with a monitoring screen, and a monitoring picture acquired by the camera 140 can be transmitted to the monitoring screen, so that the object 105 to be detected can be found and processed in time when the object is stuck in the automatic dangerous article detection equipment 100.
In some alternative embodiments, the guide mechanism 120 further includes a motive structure 124. The power structure 124 is connected to the two guide arms 121 respectively, and is configured to drive the two guide arms 121 to swing. The power structure 124 is typically integral with the fixed base of the guide arm 121 at the bottom of the guide arm 121, but may be located at the top of the guide arm 121 or elsewhere. The power structure 124 generally includes a motor, and a rotating shaft of the motor is connected to a rotating shaft portion of the guide arm 121 directly or indirectly through a gear, for providing a power for swinging the guide arm 121. A controller is arranged in one of the camera 140 and the power structure 124, and is used for receiving the position information of the object 105 to be detected, which is acquired by the camera 140, analyzing the position and the size of the width of the object 105 to be detected, further calculating the rotation angle of the guide arm 121, and controlling the power structure 124 to drive the guide arm 121 to swing. The controller may also be integrated into other control systems of the automated hazardous material detection apparatus 100.
In some alternative embodiments, the power structure 124 is a stepper motor power structure 124 or a servo motor power structure 124. The motor of the stepper motor power structure 124 is a stepper motor, and the motor of the servo motor power structure 124 is a servo motor. In practical applications, the automatic hazardous material detecting apparatus 100 needs to continuously detect a plurality of objects 105 to be detected, which are uncertain in shape, size, and weight, so that certain requirements are provided for the accuracy of the swing force, the swing speed, and the control rotation angle of the control guide arm 121 of the power structure 124. The stepping motor and the servo motor can better meet the requirements. It is well known to those skilled in the art how to select a suitable motor and combine the motor and the gear set to meet the requirements of the present embodiment, and the detailed description thereof is omitted.
The power structure 124 typically oscillates the two guide arms 121 as follows:
when the number of the sampling ports 131 is one, the controller continuously analyzes the image acquired by the camera 140, obtains information of the position of the width center point of the object 105 to be detected and information of the position of the object 105 to be detected relative to the guide arm 121, controls the power structure 124 to drive the guide arm 121 close to one side of the object 105 to be detected to swing when the object 105 to be detected is about to pass through according to the analysis result, and pushes the object 105 to be detected to the center line direction of the first conveyor belt 111 until the position of the width center point of the object 105 to be detected analyzed by the controller is over against the center of the sampling port 131 in the transmission direction, namely, the width center point of the object 105 to be detected is located on the center line of the conveying surface of the first conveyor belt 111.
When the number of the sampling ports 131 is multiple, the controller continuously analyzes the image acquired by the camera 140 and obtains information of the position of the width center point of the object 105 to be detected and information of the position of the object 105 to be detected relative to the guide arm 121, and the additional controller also needs to receive the working state of each sampling port 131. Then the controller controls the power structure 124 to drive the guide arm 121 close to one side of the object 105 to be detected to swing when the object 105 to be detected is about to pass through, and pushes the object 105 to be detected to a position opposite to the width central point of the sampling port 131 in the standby state, that is, when a certain sampling port 131 is in the detection state, the guide arm 121 pushes the object 105 to be detected to other sampling ports 131 in the standby state. Typically, the sampling ports are sequentially assigned to the articles 105 to be tested in the set position. It is understood that the detection state of the sampling port 131 includes detection sampling of the passing object 105 to be detected and analysis of the sampling result.
In some alternative embodiments, the hazardous material detector 130 includes any one or more of the following: explosive detector, drug detector, and inflammable substance detector. The utility model discloses a hazardous articles automatic check out test set 100 both can set up the hazardous articles detector 130 of different functions side by side between the interval of same conveyer belt along direction of transfer between, also can set up the hazardous articles detector 130 that has a plurality of different detector functions simultaneously, can also be on the basis of first conveyer belt 111 and second conveyer belt 112, increase the relative conveyer belt in extra interval and set up the hazardous articles detector 130 of different functions respectively between the interval of different conveyer belts. The hazardous material detector 130 may also include an alcohol detector, a metal detector, or other specific material detector, as required.
In some optional embodiments, the automated hazardous material detection apparatus 100 further includes an X-ray safety inspection device disposed on the conveying path formed by the first conveyor belt 111 and the second conveyor belt 112. The X-ray safety inspection machine 103 may cooperate with the threat detector 130 to provide more complete detection of the item 105 to be inspected. Since the X-ray safety inspection apparatus 103 itself is well known to those skilled in the art, the description thereof is omitted here.
In some alternative embodiments, the first conveyor belt 111 and the second conveyor belt 112 are adjustable speed conveyor belts. For example, the conveying speed may be slowed or stopped to allow the hazardous article detector 130 to perform more thorough and detailed detection sampling of a particular item 105 to be detected, which may be configured to include one or more of the following: larger sized articles, dark colored articles, articles with metallic luster, articles that cannot be fully inspected by the X-ray safety inspection apparatus 103, and other articles that may require critical inspection; the conveying speed can be increased to improve the passing efficiency of the empty conveyor belt or reduced to reduce the energy consumption when no object 105 to be detected exists; the transport may be stopped to trap the item 105 to be detected suspected of carrying a hazardous material inside the automated hazardous material detection equipment 100. Since the speed-adjustable conveyor belt itself is well known to those skilled in the art, the description of the present embodiment is omitted.
An article detection flow chart of the automatic dangerous article detection equipment 100 based on at least part of the above embodiments is shown in fig. 4. The article detection process of the automatic hazardous article detection equipment 100 comprises the following steps:
step S302, the article 105 to be detected enters the automatic dangerous article monitoring equipment 100 and is transported by the first conveyor belt 111;
step S304, judging whether the article 105 to be detected is over against the sampling port 131, if so, executing step S306, otherwise, executing step S308;
step S306, conveying the article 105 to be detected to a sampling port 131 by a first conveyor belt 111;
step S308, the guide arm 121 guides the object to be detected 105 to be over against the sampling port 131;
in step S310, the object 105 to be detected is transported away from the automated hazardous material detection apparatus 100 by the second conveyor belt 112.
Based on the automatic dangerous goods detection equipment 100 of at least some of the embodiments, when there are more goods 105 to be detected, the controller can flexibly control the transmission speed of the first conveyor belt 111 and the second conveyor belt 112, so as to improve the passing efficiency of the goods 105 to be detected as much as possible. If the dangerous goods detector 130 or the X-ray safety inspection instrument 103 detects that the object 105 to be detected carries the suspicion of the dangerous goods, an alarm can be automatically sent to remind an operator on duty to confirm; if the object 105 to be detected carrying serious dangerous goods suspicion is detected, the automatic alarm and the transmission stop can be automatically carried out so as to intercept the object 105 to be detected inside the automatic dangerous goods detection equipment 100. For the object 105 to be detected, which cannot be detected quickly by the hazardous article detector 130, the hazardous article automatic detection equipment 100 can automatically send an alarm to remind an operator on duty to perform a secondary inspection, without causing the object 105 to be detected to be retained in the hazardous article automatic detection equipment 100 to influence the passage of other subsequent objects 105 to be detected.
In some alternative embodiments, the standard flexible setting of the guiding position can be set, such as setting: the object 105 to be inspected is guided to a position where its width is entirely within the width of the sampling port 131, i.e., the object 105 to be inspected is guided to a position where it can completely pass through the sampling port 131 in the width direction. Specifically, for the object 105 to be detected with a width smaller than the width of the sampling port 131, it only needs to be guided to a position where the object can completely pass through the sampling port 131 without being guided to the center of the sampling port 131, for example, the object 105 to be detected is pushed by the guide arm 121 until the edge of the width is opposite to the width edge of the sampling port 131; for the object 105 to be detected whose width is not less than the width of the sampling port 131, it is still directed to face the sampling port 131. The above embodiment reduces the swing of the guide arm 121 on the basis of ensuring the full functions of the automatic hazardous material detection device 100, and is a further optimization of the above embodiment.
In some alternative embodiments, a universal conveyor belt may be used in place of the first conveyor belt 111 and the guide mechanism 120 and perform the same function.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
