[0048] Please refer to Figures 1 to 5 , this embodiment provides a detection device for detecting items in a package, including a housing 1, a moving component 2, a logic operation module 3, a signal transmitting module 4, and a signal receiving module. The housing 1 includes a first accommodation cavity 11, a second accommodation cavity 12, and a first opening 13. The first opening 13 is provided on the side wall of the housing 1 corresponding to the first accommodation cavity 11. The first accommodation cavity 11 and the second accommodation cavity 12 are adjacent and communicate with each other; the logic operation module 3 is arranged in the second accommodation cavity 12; the moving component 2 is arranged in the first accommodation cavity 11. The moving component 2 includes a driving unit 23, a slider 21, and a guide rail 22 laid along the first direction a. The slider 21 is sleeved on the guide rail 22, and the driving unit 23 is electrically connected to the logic operation module 3; the signal transmitting module 4 is arranged on the slider 21 and is electrically connected to the logic operation module 3. The signal transmitting module 4 is used to periodically emit multiple segments of first radio waves toward the first opening 13 in the direction of the package to be detected; the signal receiving module is arranged on the slider 21 and is electrically connected to the logic operation module 3. The signal receiving module is used to collect multiple segments of second radio waves and send them to the logic operation module 3. The second radio waves are generated by reflection of the first radio waves on the items in the package to be detected.

[0049] In this embodiment, the first accommodating cavity 11 and the second accommodating cavity 12 are arranged adjacent to each other. Specifically, it can be combined with Figure 1 As shown, the first accommodating cavity 11 is used to place the moving component 2, and the second accommodating cavity 12 is used to place the logic operation module 3. The first accommodating cavity 11 where the moving component 2 is located is in a long strip shape, specifically a long strip structure extending along the first direction a. Then, the guide rail 22 is in the same extending direction as the first accommodating cavity 11. This design is convenient for reducing the volume of the entire first accommodating cavity 11 and also better meets the handheld requirement of the entire detection device during use. It should be noted that the position of the first opening 13 in this embodiment is not limited. That is, the first opening 13 can be arranged on multiple side walls of the housing 1 corresponding to the first accommodating cavity 11. For example, when the first opening 13 is arranged in the radial direction of the guide rail 22, the user can directly grasp the housing 1 and align the first opening 13 with the package. Then, the slider 21 of the moving component 2 will synchronously detect the reflection signals of items at different depths in the package during the movement process. When the first opening 13 is arranged in the axial direction of the guide rail 22, the user can grasp the housing 1 from the side and orient the first opening 13 towards the package. Then, it is convenient for the user to scan the reflection signals of the items in the package along the first direction a when the slider 21 moves. Optionally, two detection devices can be arranged. The first opening 13 of one detection device is arranged in the radial direction of the guide rail 22, and the first opening 13 of the other detection device is arranged in the axial direction of the guide rail 22 to realize the scanning of items in two directions of the package and improve the detection efficiency.

[0050] The moving component 2 includes a driving unit 23, a slider 21, and a guide rail 22 laid along the first direction a. Specifically, the driving unit 23 can be a motor, preferably a stepping motor. The guide rail 22 can be a round rod-shaped guide rail 22, and the number of the guide rails 22 can be two or more to realize the smooth movement of the slider 21. The slider 21 and the guide rail 22 can also be commercially available linear slide rails, etc. This embodiment does not limit this. In some alternative embodiments, a cable carrier 24 can also be included. The cable carrier 24 can accommodate the wiring harnesses of the signal transmitting module 4 and the signal receiving module on the slider 21, and at the same time reduce the bending degree of the wiring harnesses during frequent movement, thereby extending the service life of the entire device.

[0051] In this embodiment, the signal transmitting module 4 is arranged on the slider 21, and the signal receiving module is also arranged on the slider 21. This is convenient for timely collecting the signals reflected by the items after being emitted by the signal transmitting module 4. Please refer to Figures 3 to 5, in some embodiments, the signal transmitting module 4 includes a plurality of signal transmitting subunits, and the plurality of signal transmitting subunits are distributed in a first preset manner; and / or, the signal receiving module includes a plurality of signal receiving subunits, and the plurality of signal receiving subunits are distributed in a second preset manner. The first preset manner and the second preset manner may be the same or different. Through the arrangement of the first preset manner and the second preset manner, a corresponding distribution of one signal transmitting subunit and one signal receiving subunit can be achieved to ensure the comprehensive reception of the second radio wave. Specifically, the signal transmitting module 4 and the signal receiving module may be radio frequency modules and may be radars. When the signal transmitting module 4 and the signal receiving module are integrally formed, it is preferably a millimeter-wave radar.

[0052] When the signal transmitting module 4 and the signal receiving module are integrally formed and are millimeter-wave radars, in some embodiments, the first preset manner and the second preset manner are the same; the first preset manner is 3 rows and 5 columns, and the interval between two adjacent signal transmitting modules 4 is 15 mm; and / or, the first preset manner is 3 rows and 4 columns, and the interval between two adjacent signal transmitting modules 4 is 5 mm. Optionally, in some embodiments, the signal intensity of the signal transmitting module 4 is 3.6 G to 8.3 G.

[0053] Preferably, multiple segments of the first radio wave can also be periodically emitted at a first preset frequency, and then multiple segments of the second radio wave signals within the first preset frequency can be obtained. By setting the form of the periodically transmitted radio wave, a comprehensive scan of the items in the package can be achieved, which helps to improve the recognition accuracy of the shape of the items. The first preset frequency can be adjusted according to actual needs.

[0054] Preferably, when the first radio wave is periodically emitted, different intensities can also be set. By adopting a stepped intensity setting, the multiple segments of the second radio wave obtained also have obvious intensity differences, which helps to improve the recognition accuracy of the shape of the items.

[0055] During use, based on the detection principle that the special packaging method on the outer surface of the target item will generate a strong reflected signal for the first radio wave, the detection device is aimed at the outer surface of the package, and the control logic operation module 3 drives the moving component 2 to move. At the same time, during the movement of the moving component 2, the signal transmitting module 4 emits the first radio wave, and at the same time collects and filters the second radio wave reflected by the item to obtain the second radio wave reflected by the item. Then, based on the second radio wave reflected by the item, the shape data of the item is obtained, and then the shape data of the item is recognized to determine whether the item is the target item. If there is an abnormality, the logic operation module 3 will generate a prompt message and send the prompt message to the user or display it to the user so that the user can timely discover that there is an abnormality in the current package.

[0056] In this embodiment, the reflected radio waves generated by irradiating radio waves on an article are collected and the signal strength is analyzed to obtain the shape of the article in the package, so as to identify the specific article category. The operation is simple, and there is no need to unpack the package during the use process, which not only ensures the privacy of the package but also can accurately identify the target article and improve the inspection efficiency.

It should be noted that the position of the second opening 14 is not limited in this embodiment, that is, the second opening 14 can be arranged on a plurality of side walls of the housing 1 corresponding to the second accommodation cavity 12. For example, when the first opening 13 is arranged in the axial direction of the guide rail 22, the second opening 14 can be arranged on the same side as the first opening 13, and the second opening 14 can also be arranged on the opposite side of the first opening 13; when the first opening 13 is arranged in the radial direction of the guide rail 22, the second opening 14 can also be arranged in another radial direction of the guide rail 22. In this embodiment, the number of the second openings 14 can be multiple, and the shapes, sizes and dimensions of the plurality of second openings 14 can all be different. Specifically, the shape and size of the second opening 14 are adapted to the categories of the ports arranged on the logic operation module. In some embodiments, the categories of the ports include one or more of a USB port, a Type-c port, a network card interface, a network port, a TF card interface or an SD card interface.

[0059] This way can realize the connection between the logic operation module and external devices, or can realize the electrical energy input and / or output between the electrical energy storage module in the detection device and the outside, so as to expand the application of the detection device. For example, the identification data of the articles in the logic operation module can be stored and sent through the USB port to record the inspection data of the entire inspection process and increase the traceability of the inspection data.

The display unit 5 is electrically connected to the logic operation module and can visually display the prompt information. Preferably, the display unit 5 is also provided with indicator lights. The number of indicator lights can be three. For example, the colors are red, yellow, and green. Yellow indicates that there is a fault in the detection device, red indicates an abnormal carrying of the target item, and green indicates that there is no target item in the package or the carrying quantity of the target item in the package is normal. This method can more intuitively remind the user of the inspection result and improve the inspection efficiency.
