Description

Technical Field

[0001] The present application relates to the field of logistics, and in particular to a logistics security inspection system and a logistics sorting system. Background Art

[0002] Many existing logistics transfer sites use circular sorting lines to achieve automated sorting to improve sorting efficiency. There are multiple transport carts on the circular sorting line, and multiple induction tables and sorting grids are set around the circular sorting line. The induction table (usually composed of multiple conveyor belts) transports the parcels to the transport carts on the circular sorting line, and the transport carts then take the parcels to the corresponding sorting grids, thus completing the sorting of parcels at different destinations.

[0003] At the same time, in order to strengthen the safety and regulatory management of delivery channels, a logistics security inspection system will also be installed on the induction table. The existing logistics security inspection system mainly collects the X-ray image and package information of the package through the security inspection machine and the six-sided scanning device respectively, and then binds the corresponding X-ray image and package information based on the time difference of the package's movement between the security inspection machine and the six-sided scanning device. When dangerous goods are found in the X-ray image, the corresponding package can be found accurately and quickly based on the package information.

[0004] However, due to the limited number of transport carts, there may be no empty transport carts during the peak sorting period. At this time, the induction table needs to suspend the supply of parcels and wait until a vacant transport cart is available before continuing to supply parcels. In other words, the induction table will start and stop repeatedly during the peak sorting period, and the start and stop time cannot be estimated, so the solution based on time difference binding code in the existing security inspection system cannot cope with this repeated start and stop situation. Summary of the invention

[0016] The present application also proposes another logistics security inspection system, which includes a security inspection machine and a scanning device. The security inspection machine is provided with a first conveyor belt, an image detector and a stroke sensor, wherein the first conveyor belt is used to convey the package to be inspected, the image detector is used to collect the security inspection image of the package to be inspected, and the stroke sensor is used to collect the stroke of the first conveyor belt when the image detector collects the security inspection image. The scanning device is provided with a second conveyor belt and a first sensor, wherein the second conveyor belt is connected with the first conveyor belt and is used to convey the package to be inspected, and the first sensor can be triggered by the package to be inspected passing through its position; the scanning device is used to collect the package information of the package to be inspected when the first sensor is triggered. The first sensor is also electrically connected to the security inspection machine through a wire, and when the first sensor is triggered, a trigger signal is sent to the security inspection machine through the wire, and the stroke sensor is also used to collect the stroke of the first conveyor belt when the security inspection machine receives the trigger signal, so as to bind the security inspection image and the package information according to the stroke of the first conveyor belt.

[0017] Optionally, in one embodiment, a plurality of scanning devices are provided, each of the scanning devices is provided with the first sensor, and the plurality of first sensors are electrically connected to the security inspection machine via wires.

[0018] Optionally, in one embodiment, the logistics security inspection system also includes a server, and the security inspection machine and the scanning device are electrically connected to the server; the server is used to receive the travel of the first conveyor belt or the second conveyor belt, the security inspection image and the package information, so as to bind the security inspection image and the package information according to the travel of the first conveyor belt or the second conveyor belt.

[0019] The present application also proposes a logistics sorting system, which includes the logistics security inspection system described in any of the above embodiments.

[0020] In the logistics security inspection system provided by the present application, when the package to be inspected passes through the security inspection machine, the image detector of the security inspection machine will shoot and collect the security inspection image of the package to be inspected, and at the same time, the stroke sensor will collect the stroke of the first conveyor belt in the security inspection machine. When the package to be inspected passes through the first sensor in the scanning device under the transmission of the first conveyor belt and the second conveyor belt, the first sensor will be triggered by the package to be inspected, and the scanning device will collect the package information of the package to be inspected. Because the logistics security inspection system provided by the present application also includes a second sensor, and the second sensor is installed adjacent to the first sensor, when the first sensor is triggered by the package to be inspected, the second sensor will also be triggered by the package to be inspected, and at this time the stroke sensor will collect the stroke of the first conveyor belt in the security inspection machine again.

[0021] It can be understood that because the conveyor belt drives the package to be inspected to move by friction, and the package to be inspected is stationary relative to the conveyor belt, the difference between the two strokes collected by the stroke sensor can represent the movement distance of the package to be inspected. If the difference between the two strokes is roughly equal to the installation distance between the security inspection machine and the scanning device, it means that the package to be inspected that triggers the first sensor and the second sensor is the same package, which means that the security inspection image collected when the first sensor is triggered and the package information collected when the second sensor is triggered belong to the same package and can be bound together.

[0022] That is to say, the logistics security inspection system provided by the present application binds the security inspection image and the package information of the package to be inspected based on the travel difference, and has nothing to do with the movement time difference of the package to be inspected between the security inspection machine and the scanning device. Therefore, no matter how long the induction table repeatedly starts and stops, the logistics security inspection system of the present application can accurately bind the corresponding security inspection image and the package information together, effectively solving the technical problem that the existing logistics security inspection system cannot cope with the situation where the induction table repeatedly starts and stops.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] Embodiment 1:

[0034] The embodiment of the present application provides a logistics security inspection system 100 to solve the problem that the existing logistics security inspection system 100 cannot cope with the situation where the induction table 300 is repeatedly started and stopped, which will be described below with reference to the accompanying drawings.

[0035] In the embodiments of the present application, Figure 1 As shown, the logistics security inspection system 100 is applied to the infeed table 300 of the logistics sorting system 1000. Specifically, the infeed table 300 is mainly composed of a plurality of conveyor belts connected in sequence to convey the parcels to be inspected to the circular sorting line 200. The infeed table 300 is divided into a front conveying area 310, a security inspection area 320 and a rear conveying area 330 connected in sequence. A pull-out conveyor belt is provided in the front conveying area 310, and the pull-out conveyor belt is used to pull two adjacent parcels a certain distance apart before conveying them to the security inspection area 320. The rear conveying area 330 is connected to the circular sorting line 200. The logistics security inspection system 100 provided in the present application is arranged in the security inspection area 320, and in the present embodiment, the logistics security inspection system 100 includes a security inspection machine 10, a scanning device 20 and a second sensor 40.

[0036] Among them, Figure 2 As shown, the security inspection machine 10 is provided with a first conveyor belt 11, an image detector 12 and a stroke sensor 50. The input end of the first conveyor belt 11 is connected to the pull-distance conveyor belt in the front conveying area 310, and the output end is connected to the second conveyor belt 21 in the scanning device 20, so that the first conveyor belt 11 can transport the package to be inspected from the front conveying area to the scanning device 20. In the process of transporting the package to be inspected by the first conveyor belt 11, the package to be inspected will pass through the image detector 12. The image detector 12 mainly detects the package to be inspected through X-rays, and processes the detection results into X-ray security inspection images through a processor, so as to judge whether the package to be inspected contains dangerous goods; and the specific structure, type, installation method, etc. of the image detector 12 can be realized according to the existing technology, and no specific limitation is made here.

[0037] The travel sensor 50 is used to collect the travel of the first conveyor belt 11 when the image detector 12 collects the security inspection image. Specifically, the security inspection machine 10 is generally provided with a security inspection controller 13 and a detection sensor 14. When the package to be inspected on the first conveyor belt 11 moves to the position of the detection sensor 14, the detection sensor 14 will be triggered and send a trigger signal to the security inspection controller 13. After receiving the trigger signal, the security inspection controller 13 controls the image detector 12 to collect the security inspection image, and controls the travel sensor 50 to collect the travel of the first conveyor belt 11. In order to facilitate subsequent calculations and binding, the travel is the total travel of the first conveyor belt 11 after starting, and the travel collected by the travel sensor 50 at this time can be recorded as the first total travel. It should be noted here that the specific structure, type, etc. of the travel sensor 50 can also be implemented according to the existing technology, as long as the travel of the first conveyor belt 11 can be accurately detected and collected. For example, when the first conveyor belt 11 is driven by the conveying motor, the travel sensor 50 can be an encoder, a Hall sensor, etc. installed on the conveying motor.

[0038] The scanning device 20 is provided with a second conveyor belt 21 and a first sensor 30. The input end of the second conveyor belt 21 is connected to the output end of the first conveyor belt 11, and the output end of the second conveyor belt 21 is connected to the rear conveying area 330, or the second conveyor belt 21 can also be directly connected to the ring sorting line 200, so that the second conveyor belt 21 can transport the parcel to be inspected from the first conveyor belt 11 to the rear conveying area 330 or the ring sorting line 200. It should be noted here that the front and rear positions of the security inspection machine 10 and the scanning device 20 can be interchanged, that is, the scanning device 20 is located at the upstream side of the security inspection machine 10, and the parcel information of the parcel to be inspected is first collected during security inspection, and then the security inspection image of the parcel to be inspected is collected. This is also feasible. In actual application, the specific arrangement method can be selected according to the actual situation.

[0039] The first sensor 30 is installed on one side of the second conveyor belt 21 in the width direction. Specifically, in order to prevent the package to be inspected from falling off the conveyor belt, baffles are generally provided on both sides of the conveyor belt in the width direction, and the first sensor 30 can be installed on the baffles. Alternatively, a fixing frame can be provided on one side of the second conveyor belt 21 in the width direction, and the first sensor 30 is installed on the fixing frame, so that when the second conveyor belt 21 is conveying the package to be inspected, the first sensor 30 can be triggered by the package to be inspected passing through its position. Specifically, in this embodiment, the first sensor 30 is a photoelectric sensor. When the package to be inspected passes the position of the first sensor 30, the package to be inspected will block the light beam emitted by the first sensor 30, causing the light intensity to change. The first sensor 30 converts the change in light intensity into a change in an electrical signal, and then outputs a corresponding trigger signal.

[0040] The scanning device 20 can collect the package information of the package to be inspected when the first sensor 30 is triggered. Specifically, the scanning device 20 is further provided with at least a scanning controller 23 and a scanner 22. When the first sensor 30 is triggered, a trigger signal is sent to the controller, and the controller controls the scanner 22 to scan and collect the package information of the package to be inspected according to the trigger signal. The package information generally includes the order number (or label number), the consignor information, the consignee information, etc. Among them, the structure and type of the scanning device 20 can be implemented according to the existing technology. For example, the scanning device 20 can be a six-sided scanning device, and then each surface of the package to be inspected can be scanned to smoothly collect the package information.

[0041] In the logistics security inspection system 100, after the security inspection image and package information of the package to be inspected are collected separately, it is also necessary to bind the security inspection image and the package information together, so that when dangerous goods are found in the security inspection image, the corresponding package can be found quickly and accurately according to the bound package information. However, the existing logistics security inspection system 100 binds the security inspection image and the package information based on the time difference, which cannot cope with the situation where the supply table 300 is repeatedly started and stopped and the start and stop time cannot be estimated. Therefore, in order to solve the above problems, the logistics security inspection system 100 of the present application is also provided with a second sensor 40, which is also a photoelectric sensor, and the second sensor 40 is installed in a position close to the first sensor 30, so that the first sensor 30 and the second sensor 40 are almost triggered by the package to be inspected at the same time, and the principle of the second sensor 40 being triggered by the package to be inspected can refer to the first sensor 30, which will not be repeated here. In addition, the second sensor 40 is also electrically connected to the security inspection machine 10 through a wire, and the stroke sensor 50 is also used to collect the stroke of the first conveyor belt 11 when the second sensor 40 is triggered by the package to be inspected. Specifically, the security inspection machine 10 is also provided with a security inspection controller 13, which can be a PLC controller (i.e., Programmable Logic Controller) or a single-chip microcomputer controller. The second sensor 40 and the stroke sensor 50 are both electrically connected to the security inspection controller 13. When the second sensor 40 is triggered, a trigger signal is sent to the security inspection controller 13 through a wire. The security inspection controller 13 is used to control the stroke sensor 50 to collect the stroke of the first conveyor belt 11 when receiving the trigger signal. Similarly, for the convenience of subsequent calculation and binding, the stroke is also the total stroke of the first conveyor belt 11 since its start, and the stroke collected by the stroke sensor 50 at this time can be recorded as the second total stroke.

[0042] It can be understood that, because the first sensor 30 and the second sensor 40 are triggered almost at the same time, and when the first sensor 30 is triggered, the scanning device 20 will collect the package information of the package to be inspected, and when the second sensor 40 is triggered, the stroke sensor 50 in the security inspection machine 10 also collects the stroke of the first conveyor belt 11, so when the package to be inspected passes through the scanning device 20 and the package information is collected, the stroke sensor 50 also collects the second total stroke of the first conveyor belt 11. And because the conveyor belt drives the package to be inspected to move by friction, the package to be inspected is stationary relative to the conveyor belt, so the difference between the first total stroke and the second total stroke can represent the movement distance of the package to be inspected. Therefore, when the difference between the first total stroke and the second total stroke is approximately equal to the installation distance between the security inspection machine 10 and the scanning device 20, it means that the package to be inspected that triggers the first sensor 30 and the second sensor 40 is the same package, which means that the security inspection image collected when the first sensor 30 is triggered and the package information collected when the second sensor 40 is triggered belong to the same package and can be bound together.

[0043] That is to say, the logistics security inspection system 100 provided by the present application binds the security inspection image and the package information of the package to be inspected based on the travel difference, and has nothing to do with the movement time difference of the package to be inspected between the security inspection machine 10 and the scanning device 20. Therefore, no matter how long the induction table 300 is repeatedly started and stopped, the logistics security inspection system 100 of the present application can accurately bind the corresponding security inspection image and the package information together, effectively solving the technical problem that the existing logistics security inspection system 100 cannot cope with the situation where the induction table 300 is repeatedly started and stopped.

[0044] It should be noted that, as to the specific value of "the difference between the first total stroke and the second total stroke" to be roughly equal to "the installation distance between the security inspection machine 10 and the scanning device 20", in actual judgment, a range can be set according to the installation distance between the security inspection machine 10 and the scanning device 20 (specifically, the installation distance between the detection sensor 14 in the security inspection and the first sensor 30 in the scanning device 20), the pulling distance between two adjacent packages, etc. When the difference between the first total stroke and the second total stroke is within the set range, it can be indicated that the packages that trigger the first sensor 30 and the second sensor 40 are the same package. For example, when the pulling distance between two adjacent packages to be inspected is 900 mm and the installation distance between the security inspection machine 10 and the scanning device 20 is 5000 mm, the difference between the upper limit value and the lower limit value of the set range can be 1.5 times the pulling distance, that is, 1350 mm. Therefore, based on the installation distance between the security inspection machine 10 and the scanning device 20 being 5000 mm, the lower limit value of the set range is 4325 mm (that is, 5000-(1350 / 2)=4325), and the maximum value is 5675 mm (that is, 5000+(1350 / 2)=5675).

[0045] In addition, regarding the point that “the second sensor 40 is installed adjacent to the first sensor 30”, in this embodiment, the installation distance between the first sensor 30 and the second sensor 40 is not greater than 15 cm, for example, the installation distance between the first sensor 30 and the second sensor 40 can be 1 cm, 2 cm, 3 cm, 5 cm, 8 cm, 10 cm, 12 cm, 15 cm, etc. It can be understood that if the installation distance between the first sensor 30 and the second sensor 40 is too large, the synchronization between the first sensor 30 and the second sensor 40 when being triggered will be poor, thereby affecting the success rate and accuracy of the mutual binding between the security inspection image and the package information. Therefore, by making the installation distance between the first sensor 30 and the second sensor 40 not greater than 15 cm, it can be ensured that the first sensor 30 and the second sensor 40 are triggered almost at the same time, thereby ensuring the success rate and accuracy of the mutual binding between the security inspection image and the package information.

[0046] Furthermore, the first sensor 30 and the second sensor 40 are set at the same installation height relative to the second conveyor belt 21. It can be understood that if the first sensor 30 and the second sensor 40 are installed at different heights, it may cause the package to be inspected at a certain height to only trigger the first sensor 30 or only trigger the second sensor 40, thereby causing the corresponding travel data or package information to be missing and affecting the binding. Therefore, by setting the first sensor 30 and the second sensor 40 at the same installation height relative to the second conveyor belt 21, it is possible to avoid the situation where only one of the sensors is triggered, ensuring the smooth binding of the security inspection image and the package information.

[0047] Furthermore, in the extension direction of the second conveyor belt 21, the second sensor 40 is closer to the security inspection machine 10 than the first sensor 30. It can be understood that because the second sensor 40 is electrically connected to the security inspection machine 10 through a wire, when the second sensor 40 is arranged closer to the security inspection machine 10 than the first sensor 30, it will be more convenient to wire and connect the second sensor 40 to the security inspection machine 10.

[0048] In this embodiment, the first conveyor belt 11 and the second conveyor belt 21 have the same running speed, and the first conveyor belt 11 and the second conveyor belt 21 start and stop synchronously. According to the introduction above, this application collects the front and rear strokes of the first conveyor belt 11 through the stroke sensor 50. On the one hand, it is based on the fact that some security inspection machines 10 on the market will have their own stroke sensors 50. Then, when applying the technical solution of this application, it is only necessary to add the corresponding control program so that the stroke sensor 50 in the security inspection machine 10 can collect the stroke of the first conveyor belt 11 at a specific time, and there is no need to make major changes to the security inspection machine 10. On the other hand, the stroke of the first conveyor belt 11 can always be used as a reference for image code binding, reducing detection variables and improving the success rate and accuracy of image code binding. However, because the package to be inspected is not only conveyed by the first conveyor belt 11, but also conveyed by the second conveyor belt 21, in order to avoid the situation where there is a stroke difference between the first conveyor belt 11 and the second conveyor belt 21, which results in the stroke of the first conveyor belt 11 not representing the stroke of the package to be inspected, this embodiment makes the running speeds of the first conveyor belt 11 and the second conveyor belt 21 the same, and the first conveyor belt 11 and the second conveyor belt 21 start and stop synchronously, so as to ensure that the stroke of the first conveyor belt 11 represents the stroke of the package to be inspected, thereby better coping with the situation where the induction table 300 is repeatedly started and stopped.

[0049] In this embodiment, if Figure 2 As shown, because there are usually many types of parcels to be inspected, for example, some parcels to be inspected are affixed with waybill numbers, while some parcels to be inspected are affixed with label numbers, and when collecting parcel information of the parcels to be inspected, different scanners 22 are usually required to scan. Therefore, in this embodiment, the scanning device 20 includes multiple scanners 22, and the multiple scanners 22 are arranged at intervals along the second conveyor belt 21 to collect different types of parcel information respectively. In order to ensure that each scanner 22 can collect parcel information in a timely manner when the parcel to be inspected reaches each scanner 22, the first sensor 30 includes multiple sensing photoelectric ( Figure 2 30 and 31), a plurality of photoelectric sensors are mounted one by one on a plurality of scanners 22. When the photoelectric sensors are triggered by the package to be inspected, the corresponding scanner 22 will collect the package information of the package to be inspected. At the same time, in order to make each scanner 22 collect the package information, the security inspection machine 10 also controls the stroke sensor 50 to collect the stroke of the first conveyor belt 11 at the same time. In this embodiment, the second sensor 40 includes a plurality of auxiliary photoelectric sensors ( Figure 240 and 41), multiple auxiliary photoelectric devices are electrically connected to the security inspection machine 10 respectively, and multiple auxiliary photoelectric devices are installed on multiple scanners 22 one by one, and the sensing photoelectric device and the auxiliary photoelectric device on each scanner 22 are arranged adjacent to each other. Then, when the sensing photoelectric device on each scanner 22 is triggered, the adjacent auxiliary photoelectric device will also be triggered, so that when each scanner 22 collects the package information of the package to be inspected, the security inspection machine 10 will also control its stroke sensor 50 to collect the stroke of the first conveyor belt 11, so as to bind the security inspection image and the package information according to the stroke difference of the first conveyor belt 11 and the installation distance between the security inspection machine 10 and the corresponding scanner 22.

[0050] It should be noted that a package to be inspected usually has only one type of information, for example, the package to be inspected only has a waybill number but no label number, or only has a label number but no waybill number. Only one scanner 22 among multiple scanners 22 collects the real package information, and the information collected by other scanners 22 is displayed as empty. Therefore, before binding, the package information collected by multiple scanners 22 can be merged to obtain the real package information, and then bound to the corresponding security inspection image.

[0051] For example, in this embodiment, Figure 2 As shown, the scanning device 20 includes a six-sided scanner 221 and an RFID identifier 222 (i.e., Radio Frequency Identification), wherein the six-sided scanner 221 is used to collect the waybill information of the package to be inspected, and the RFID identifier 222 is used to collect the RFID tag information of the package to be inspected. The first sensor 30 includes a first sensing photoelectric 31 installed on the six-sided scanner 221 and a second sensing photoelectric ( Figure 2 30), the second sensor 40 includes a first auxiliary photoelectric 41 and a second auxiliary photoelectric ( Figure 2 40), the first auxiliary photoelectric 41 is installed adjacent to the first sensing photoelectric 31, and the second auxiliary photoelectric is installed adjacent to the second sensing photoelectric. If the parcel to be inspected is affixed with a waybill number, the six-sided scanner 221 collects the waybill information of the parcel to be inspected, and finally binds the security inspection image with the waybill information of the parcel to be inspected; if the parcel to be inspected is affixed with an RFID tag number, the RFID identifier collects the RFID tag information of the parcel to be inspected, and finally binds the security inspection image with the RFID tag information of the parcel to be inspected.

[0052] Embodiment 2:

[0053] like Figure 3As shown, the present application also proposes another logistics security inspection system 100, which is also applied to the supply table 300 of the logistics sorting system 1000. The specific application environment can refer to the introduction in the previous embodiment 1, and the logistics security inspection system 100 in this embodiment also includes a security inspection machine 10, a scanning device 20 and a second sensor 40.

[0054] The security inspection machine 10 is provided with a first conveyor belt 11, a first sensor 30 and an image detector 12. The first conveyor belt 11 is used to convey the package to be inspected. The first sensor 30 can be triggered by the package to be inspected passing through its position. The image detector 12 is used to collect the security inspection image of the package to be inspected when the first sensor 30 is triggered. Specifically, in this embodiment, the first conveyor belt 11 and the image detector 12 are both configured in the same manner as in the embodiment. The first sensor 30 in the security inspection machine 10 is equivalent to the detection sensor 14 in the first embodiment. Both are used to detect whether the package to be inspected passes through, and send a signal to the security inspection controller 13 of the security inspection machine 10 when the first sensor 30 is triggered. The security inspection controller 13 then controls the image detector 12 to collect the security inspection image of the package to be inspected.

[0055] The scanning device 20 is provided with a second conveyor belt 21, a scanner 22 and a stroke sensor 50. The second conveyor belt 21 is connected to the first conveyor belt 11 and is used to convey the parcel to be inspected. The scanner 22 is used to collect the parcel information of the parcel to be inspected. The stroke sensor 50 is used to collect the stroke of the second conveyor belt 21 when the scanner 22 collects the parcel information. Specifically, in this embodiment, the second conveyor belt 21 and the scanner 22 are both configured in the same manner as in the first embodiment. The difference is that the scanning device 20 in this embodiment is provided with a stroke sensor 50. The stroke sensor 50 collects the stroke of the second conveyor belt 21 when the scanning device 20 collects the parcel information. In order to facilitate subsequent calculation and binding, the stroke is the total stroke of the second conveyor belt 21 after it is started. At this time, the stroke collected can be recorded as the first total stroke. The specific structure and type of the stroke sensor 50 can refer to the relevant introduction in the first embodiment.

[0056] The difference between this embodiment and the first embodiment is that the second sensor 40 is installed on the security inspection machine 10, and the second sensor 40 is installed adjacent to the first sensor 30, that is, when the package to be inspected passes through and triggers the first sensor 30 of the security inspection machine 10, the second sensor 40 will also be triggered by the package to be inspected. At the same time, the second sensor 40 is also electrically connected to the scanning device 20 through a wire, and the stroke sensor 50 is also used to collect the stroke of the second conveyor belt 21 when the second sensor 40 is triggered by the package to be inspected, so as to bind the security inspection image and the package information according to the stroke of the scanning device 20. Specifically, the scanning device 20 is also provided with a scanning controller 23, which can be a PLC controller or a single-chip microcomputer controller. The second sensor 40 and the stroke sensor 50 are both connected to the scanning controller 23. When the second sensor 40 is triggered, it will send a trigger signal to the scanning controller 23 in the scanning device 20 through a wire. The scanning controller 23 controls the stroke sensor 50 to collect the stroke of the second conveyor belt 21 according to the trigger signal. The stroke is the total stroke of the second conveyor belt 21 after starting. At this time, the collected stroke can be recorded as the second total stroke.

[0057] It can be understood that, because the first sensor 30 and the second sensor 40 are triggered almost at the same time, and when the first sensor 30 is triggered, the security inspection machine 10 will collect the security inspection image of the package to be inspected, and when the second sensor 40 is triggered, the stroke sensor 50 in the scanning device 20 also collects the stroke of the second conveyor belt 21, so when the package to be inspected passes through the security inspection machine 10 and the security inspection image is collected, the stroke sensor 50 also collects the second total stroke of the first conveyor belt 11. And because the conveyor belt drives the package to be inspected to move by friction, the package to be inspected is stationary relative to the conveyor belt, so the difference between the first total stroke and the second total stroke can represent the movement distance of the package to be inspected. Therefore, when the difference between the first total stroke and the second total stroke is approximately equal to the installation distance between the security inspection machine 10 and the scanning device 20, it means that the package to be inspected that triggers the first sensor 30 and the second sensor 40 is the same package, which means that the security inspection image collected when the first sensor 30 is triggered and the package information collected when the second sensor 40 is triggered belong to the same package and can be bound together.

[0058] That is to say, the logistics security inspection system 100 provided in this embodiment also binds the security inspection image and the package information of the package to be inspected based on the travel difference, and has nothing to do with the movement time difference of the package to be inspected between the security inspection machine 10 and the scanning device 20. Therefore, no matter how long the induction table 300 is repeatedly started and stopped, the logistics security inspection system 100 of the present application can accurately bind the corresponding security inspection image and the package information together, effectively solving the technical problem that the existing logistics security inspection system 100 cannot cope with the situation where the induction table 300 is repeatedly started and stopped.

[0059] In addition, in this embodiment, the positional relationship between the first sensor 30 and the second sensor 40, and the motion relationship between the first conveyor belt 11 and the second conveyor belt 21 can be set the same as in the first embodiment.

[0060] The present embodiment is also different from the first embodiment in that, in the present embodiment, there are multiple scanning devices 20, and the multiple scanning devices 20 are respectively used to collect different types of package information, for example, some scanning devices 20 are used to collect waybill information of the package to be inspected, and some scanning devices 20 are used to collect label information of the package to be inspected. And the multiple scanning devices 20 include a main device 24 and a plurality of auxiliary devices 25, and the "several" means that the number is not limited, and can be one, two, three, four, five, etc. Among them, each auxiliary device 25 is provided with a third sensor 60, and the logistics security inspection system 100 also includes a plurality of fourth sensors 70, and the plurality of fourth sensors 70 are installed on the plurality of auxiliary devices 25 in a one-to-one correspondence, and the third sensor 60 and the fourth sensor 70 on each auxiliary device 25 are arranged adjacent to each other; the second sensor 40 and the plurality of fourth sensors 70 are respectively electrically connected to the main device 24 through wires. Specifically, in this embodiment, when there are multiple scanning devices 20, it means that there are also multiple second conveyor belts 21. In order to reduce variables, this solution selects one of the scanning devices 20 as the main device 24, and the other scanning devices 20 as the auxiliary devices 25, and each fourth sensor 70 on each auxiliary device 25 and the second sensor 40 on the security inspection machine 10 are electrically connected to the main device 24 respectively, so that no matter the package to be inspected passes through the security inspection machine 10, the main device 24 or the auxiliary device 25, what is collected is the travel of the second conveyor belt 21 of the main device 24. In this way, the detection variables can be reduced and the success rate and accuracy of the image code binding can be improved.

[0061] For example, in this embodiment, Figure 3As shown, the scanning device 20 includes a six-sided scanning device and an RFID identification device. The six-sided scanning device is used to collect the waybill information of the package to be inspected, and the RFID identification device is used to collect the label information of the package to be inspected. The RFID device is used as a secondary device 25 and is provided with a third sensor 60 and a fourth sensor 70. The six-sided scanning device is used as a main device 24, and the second sensor 40 and the fourth sensor 70 are respectively electrically connected to the six-sided scanning device through wires. It can be understood that if the package to be inspected has no waybill number but a label number, when the package to be inspected passes through the six-sided scanning device, the package information collected by the six-sided scanning device is actually empty. At this time, the label information needs to be collected by the RFID device to achieve binding with the security inspection image. In order to ensure that the collected label information and the security inspection image correspond to the same package, when the package to be inspected passes through the RFID device and the label information is collected, the fourth sensor 70 is also needed to prompt the stroke sensor 50 to continue to collect the stroke of the second conveyor belt 21 in the six-sided scanning device, and then determine whether the collected label information and the security inspection image belong to the same package through the stroke difference, thereby ensuring the accuracy of the image code binding.

[0062] Embodiment three:

[0063] like Figure 4 As shown, the present application also proposes another logistics security inspection system 100 , which is different from both the first and second embodiments in that the logistics security inspection system 100 includes a security inspection machine 10 and a scanning device 20 , but does not include a second sensor 40 .

[0064] Specifically, the security inspection machine 10 is provided with a first conveyor belt 11, an image detector 12 and a travel sensor 50. The first conveyor belt 11 is used to convey the parcel to be inspected, the image detector 12 is used to collect the security inspection image of the parcel to be inspected, and the travel sensor 50 is used to collect the travel of the first conveyor belt 11 when the image detector 12 collects the security inspection image. The scanning device 20 is provided with a second conveyor belt 21 and a first sensor 30. The second conveyor belt 21 is connected to the first conveyor belt 11 and is used to convey the parcel to be inspected. The first sensor 30 can be triggered by the parcel to be inspected passing through its position; the scanning device 20 is used to collect the parcel information of the parcel to be inspected when the first sensor 30 is triggered.

[0065] It should be noted that the security inspection machine 10 and the scanning device 20 in this embodiment can be configured in the same manner as in the embodiment, but what is different from the first and second embodiments is that the first sensor 30 in the scanning device 20 is also electrically connected to the security inspection machine 10 via a wire, specifically, it is electrically connected to the security inspection controller 13 in the security inspection machine 10, and when the first sensor 30 is triggered, a trigger signal is sent to the security inspection machine 10 via a wire, and the travel sensor 50 is also used to collect the travel of the first conveyor belt 11 when the security inspection machine 10 receives the trigger signal, so as to bind the security inspection image and the package information according to the travel of the first conveyor belt 11.

[0066] That is to say, both this embodiment and the first embodiment can solve the technical problem that the existing logistics security inspection system 100 cannot cope with the situation where the induction table 300 is repeatedly started and stopped, and the principle of solving the problem is the same. The difference is that this embodiment directly electrically connects the first sensor 30 in the scanning device 20 to the security inspection machine 10, and then when the first sensor 30 is triggered, the first sensor 30 will simultaneously send a trigger signal to the scanning device 20 and the security inspection machine 10, so that when the scanning device 20 collects the package information of the package to be inspected, the security inspection machine 10 also controls its stroke sensor 50 to collect the stroke of the first conveyor belt 11. It can be understood that such a setting can make the structure of the logistics security inspection system 100 simpler and the cost lower.

[0067] Furthermore, in this embodiment, there are multiple scanning devices 20, which are respectively used to collect different types of package information, and each scanning device 20 is provided with a first sensor 30, and the multiple first sensors 30 are respectively electrically connected to the security inspection machine 10 through wires. In this way, each time the package to be inspected passes through a scanning device 20, the security inspection machine 10 will control the stroke sensor 50 to collect the stroke of the first conveyor belt 11.

[0068] Embodiment 4:

[0069] like Figure 5 As shown, this embodiment is based on the first embodiment, the second embodiment or the third embodiment, so that the logistics security inspection system 100 also includes a server 80, and the security inspection machine 10 and the scanning device 20 are both electrically connected to the server 80; the server 80 is used to receive the travel of the first conveyor belt 11 or the second conveyor belt 21, the security inspection image and the package information, so as to bind the security inspection image and the package information according to the travel of the first conveyor belt 11 or the second conveyor belt 21. Specifically, the server 80 can be connected to the security inspection machine 10 and the scanning device 20 respectively through the communication interface, so that the security inspection machine 10 and the scanning device 20 can upload the security inspection image, the package type and the corresponding travel data to the server 80, and then use the more powerful computing and processing capabilities of the server 80 to bind the security inspection image and the package information, thereby improving the image code binding efficiency.

The supply platform 300 is used to transport the parcels to the transport carts 210 on the circular sorting line 200, and the transport carts 210 then take the parcels to the corresponding sorting openings 400, thus completing the sorting of parcels at different destinations. Among them, the supply platform 300 can be divided into a front conveying area 310, a security inspection area 320 and a rear conveying area 330 which are connected in sequence. A pull-out conveyor belt is provided in the front conveying area 310, and the pull-out conveyor belt is used to pull a certain distance between two adjacent parcels before sending them to the security inspection area 320. The rear conveying area 330 is connected with the circular sorting line 200, and the logistics security inspection system 100 provided in the present application is arranged in the security inspection area 320 to perform security inspections on the parcels.
