In some embodiments, the position detection device may be configured to detect the position of the target collection site, and adjust the position of the odor detection assembly 4 based on the position of the target collection site to enable the odor detection assembly 4 to aspirate a sample from the target collection site of the subject. For example, the position detecting device may automatically send a signal to the guiding mechanism 43 or the robot arm 41 to move the guiding mechanism 43 or the robot arm 41, so that the electronic nose 42 reaches the target collecting site.

In the case of bulk goods, the position detection device can first adjust the electronic nose 42 to a predetermined position, the vehicle passing through the passage formed by the carrier 1, the electronic nose 42 taking the aspirated sample during the passage of the vehicle. Alternatively, the vehicle may be stationary in the passageway and the position sensing device may adjust the guide mechanism or mechanical arm to cause the electronic nose 42 to take samples of the bulk cargo by aspiration in different orientations. The former vehicle does not stop through the mode of breathing in the sample, has improved inspection efficiency, and the latter mode detects more accurately.

Further, the position detection device may include: the image acquisition assembly and the image recognition component. The image acquisition assembly is used for acquiring image information of an object to be detected. The image recognition component is used for recognizing the image information of the object to be detected and determining the position of the target acquisition part. Further, the image acquisition assembly may include: at least one of a scanning unit and an image pickup unit. The scanning component can be used for scanning the object to be detected and acquiring the coordinate information of the outline of the object to be detected. The image recognition component is used for recognizing the outline of the bulk cargo according to the coordinate information of the outline of the object to be detected and determining a target acquisition part. Alternatively, the camera component may be used to capture images of the object to be detected. The image recognition component is used for recognizing the outline of the bulk cargo according to the image of the object to be detected and determining the target acquisition part.

The scanning component (for example, a laser scanner) can acquire the outline and coordinate information of the object to be detected through laser scanning. The imaging component (e.g., high definition camera) may capture an image of the object under examination. The image acquisition assembly sends the acquired information of the object to be detected to the image recognition assembly. The image recognition component can recognize the outline of the vehicle and determine the target acquisition site of the outline. The target collection site may be a location that is a predetermined distance from a predetermined point of the bulk cargo contour and may maintain the e-nose 42 a safe distance from the bulk cargo contour without contact. Different appearance profiles preset different points, should preset the point and can make the more accurate comprehensive sampling of breathing in of electron nose. For example, the preset point is a point where a center point of a three-dimensional body formed by the outline extends vertically upward to intersect with the outline surface, a preset distance in the vertical upward direction of the point is the target collection portion, and the preset distance may be slightly greater than a distance difference between the point and a highest point of the outline. The target acquisition site may also be determined in other ways, and is not limited to the illustrated example.

After the position detection device determines the target collection part, the electronic nose is adjusted to reach the target collection part, the vehicle runs through the channel, the electronic nose is indicated to be started to suck air for sampling under the condition that the position detection device detects that bulk goods enter a sampling range of the electronic nose, and the electronic nose is indicated to stop sucking air for sampling and detect gas after the bulk goods leave the sampling range of the electronic nose.

In the case where the object to be inspected is a container, since the position of the vent hole in the container needs to be accurately detected as a target collection portion, the vehicle can be stopped for inspection. The indication information may be set to indicate that the vehicle is stopped at a preset position in the passageway. For example, the position detection means may issue a warning message (e.g., a signal light, a voice, etc.) to stop the vehicle when it is detected that the vehicle is approaching the preset position. Or, the vehicle may also directly run through the passage, and the position detection device enables the electronic nose 42 to follow the target collection portion by detecting the position of the vent hole on the container during the running process of the vehicle, and performs air suction sampling on the vent hole on the container.

The image capturing assembly in the position detecting device may include at least one of a scanning component and a camera component. The scanning unit (e.g., a laser scanner) may be configured to scan the object to be inspected and obtain coordinate information of the contour of the object to be inspected. The image recognition component is used for recognizing the air holes of the container according to the coordinate information of the outline of the object to be detected, so that the target acquisition part is determined. Alternatively, the camera component may be used to capture images of the object to be detected. The image recognition component is used for recognizing the air vent of the container according to the image of the object to be detected, so that the target acquisition part is determined. The scanning component or the camera component can be arranged on a position adjusting mechanism (for example, arranged on a mechanical arm and arranged adjacent to an electronic nose) in the smell detection component 4, and under the condition that the vehicle is static, the position adjusting mechanism can be adjusted to enable the scanning component or the camera component to move so as to acquire image information of different parts of different containers.

The scanning component and the camera shooting component can work in a matched mode, and the scanning component is used for scanning the object to be detected and obtaining coordinate information of the outline of the object to be detected. The camera shooting component is used for collecting the image of the container under the condition that the distance between the container and the camera shooting component reaches a preset camera shooting distance. The image recognition component is used for determining the distance between the container and the camera component according to the coordinate information of the outline of the object to be detected, and determining the position of the vent hole as the position of the target acquisition part according to the image of the container. The scanning component basically detects the position and contour information of the object to be detected, and the camera shooting component accurately collects the image of the container. In this case, the camera member may be provided on the position adjusting mechanism in the smell detection assembly 4, and the camera member may be moved to accurately capture an image of the container.

In some embodiments, the electronic nose 42 includes a sampler including: a suction cup and a pressure detection component. The sucking disc can be used for adsorbing at target collection position and taking the sample of breathing in. The pressure detection part can be arranged on the sucker and used for detecting the pressure between the sucker and the object to be detected. And a position adjusting mechanism for stopping the operation when the detection value of the pressure detecting component exceeds the preset pressure. The sucking disc can adsorb the sample thief at the target acquisition position, can not remove more and press close to the target during the sampling, promotes the sampling effect.

In the aforementioned embodiments, in the case that the position detection device includes the image capturing assembly, the device may further include a simple distance measurement component, and the distance measurement component instructs the image capturing assembly to start working when detecting that the object to be detected reaches the preset position.

In some embodiments, as shown in FIG. 1, the checkpoint may further include: the radiation detection device 5 identifies a radioactive substance in the specimen. The radiation detection device 5 includes, for example: a nuclide identification component for detecting radioactive substances when the inspection station moves relative to the object to be inspected; and/or a gamma camera for detecting radioactive materials while the inspection station is stationary relative to the object to be inspected.

In some embodiments, the backscattered light beam emitted by the radiation scanning assembly 2, the projected imaging light beam, and the acquired signals emitted by the radiation detection device 5 are emitted at different times. For example, as shown in fig. 3, the projected imaging light beam emitted by the radiation scanning assembly 2 is a pulse signal, and the backscattered light beam emitted by the radiation scanning assembly 2 and the collected signal emitted by the radiation detection device 5 are a first square wave signal and a second square wave signal, respectively. The pulse signal is at the falling edge of the first square wave signal, the second square wave signal is at the low level when the first square wave signal is at the high level, and the second square wave signal is at the high level when the first square wave signal is at the low level. Or the pulse signal is at the rising edge of the first square wave signal, the second square wave signal is at the low level when the first square wave signal is at the high level, and the second square wave signal is at the high level when the first square wave signal is at the low level.

The back scattering light beam and the projection imaging light beam which are emitted by the ray scanning component 2 and the acquisition signal which is emitted by the radiation detection device 5 are emitted at different time, so that mutual interference can be avoided, and the detection accuracy is improved.

In some embodiments, the checkpoint may further comprise vehicle identification means (6) for identifying at least one of the model, license plate or container number of the vehicle to determine whether to activate the radiation scanning assembly 2, the disinfection device 3, the odor detection assembly 4 or the radiation detection device 5, etc. The inspection station can be linked with a customs system to acquire inspection task allocation information, and for different vehicles or containers, for example, whether X-ray inspection is required, whether electronic sniffing detection is required, whether disinfection is required, and the like.
