Description

Technical Field

[0001] The present invention relates to the technical field of logistics distribution management, and in particular to a cargo security inspection and sorting method and system. Background Art

[0002] The current air cargo security screening process usually involves using a roller conveyor to transport the cargo to an X-ray machine for scanning, while security personnel conduct image interpretation next to the on-site X-ray machine. Once suspicious items are found, refer to Figure 4 If suspicious goods are found, the security personnel will manually operate the X-ray machine and the conveyor to reverse the goods, and then open the package for inspection. At this time, the goods on the front and rear conveyors will be reversed together. At this time, the goods cannot be received. The normal goods that have passed the X-ray machine must also be reversed, so the efficiency of receiving goods is low and the security inspection environment is not good;

[0003] After confirmation that there are no problems, the goods need to pass through the X-ray machine again before entering the controlled area (i.e. the airside), and then be sent to the corresponding flight by means of transportation such as small trucks. However, in the context of ever-increasing cargo throughput, this traditional security inspection model can also lead to serious cargo accumulation, seriously affecting security inspection efficiency and increasing the workload of workers. Summary of the invention

[0004] In view of the above problems or problems existing in the prior art, the present invention is proposed.

[0005] Therefore, the purpose of the present invention is to provide a cargo security inspection and sorting method, which realizes synchronous transportation, real-time tracking and efficient security inspection, significantly improves the efficiency and safety of air cargo handling, and reduces the labor intensity of manual labor.

[0007] Displacement monitoring units are installed on the scanning conveyor and the sorting conveyor respectively to obtain virtual position information of the goods;

[0008] The image information of the goods on the scanning conveyor and the sorting conveyor is obtained respectively. The security inspection unit determines whether the goods are abnormal based on the image information and virtual position information to ensure that the goods that pass through the sorting machine and arrive at the receiving platform meet the normal standards.

[0009] As a preferred solution of the cargo security inspection and sorting method of the present invention, the security inspection unit determines whether the cargo is abnormal based on the image information and the virtual location information, including the following steps:

[0010] The security inspection unit determines whether the current goods are abnormal based on the image information of the current goods on the scanning conveyor;

[0011] If the current cargo is abnormal, the virtual location information of the abnormal cargo is sent to the system control unit;

[0012] The system control unit determines the abnormal goods based on the virtual position information of the abnormal goods and the image information of the abnormal goods on the sorting conveyor, and controls the exit direction of the sorting machine to convey the abnormal goods to the security inspection unit.

[0013] As a preferred solution of the cargo security inspection and sorting method described in the present invention, the installed speed monitoring unit is an encoder.

[0014] As a preferred solution of the cargo security inspection and sorting method of the present invention, the step of determining that the transport speeds of the scanning conveyor and the sorting conveyor are consistent comprises the following steps:

[0015] Based on the encoder, pulse signals corresponding to the scanning conveyor and the sorting conveyor are respectively obtained;

[0016] The rotation speeds of the scanning conveyor and the sorting conveyor are calculated based on the frequency of the pulse signal changes per unit time.

[0019] Based on the encoder, pulse signals corresponding to the scanning conveyor and the sorting conveyor are respectively obtained;

[0020] The real-time displacement of the scanning conveyor and the sorting conveyor are calculated according to the number of changes in the pulse signal per unit time.

[0021] As a preferred solution of the cargo security inspection and sorting method described in the present invention, the speeds of the first conveyor and the second conveyor are determined to ensure that the cargo is instantaneously accelerated when it transitions from the first conveyor to the second conveyor, thereby generating a first distance with adjacent cargo still on the first conveyor, to ensure that the cargo that passes first can complete the scanning task before the cargo that passes later enters the scanning conveyor.

[0022] In order to further solve the above technical problems, the present invention provides the following technical solutions: a speed monitoring and synchronization control module, which ensures that the transportation speeds of the scanning conveyor and the sorting conveyor are consistent, and monitors and adjusts the speeds of both through an encoder; a displacement monitoring and virtual position tracking module, which uses an encoder to calculate the rotation angle of the conveyor and the linear displacement of the goods, and generates virtual position information of the goods; an image information acquisition and analysis module, which uses an X-ray machine to scan the goods and combines the virtual position information, and the security inspection unit determines whether the goods are abnormal; an abnormal goods processing module, when abnormal goods are detected, the system control unit guides the sorting machine to transfer the abnormal goods to the security inspection unit for further inspection according to its virtual position information.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and provides a cargo security inspection and sorting method, comprising:

[0036] S1: A speed monitoring unit is installed on the scanning conveyor and the sorting conveyor respectively to ensure that the transport speeds of the scanning conveyor and the sorting conveyor are consistent.

[0037] It should be noted that the scanning conveyor includes a conveyor and an X-ray machine to form a scanning area, and the sorting conveyor refers to a conveyor that transfers the scanned goods to the sorting machine, which is composed of the third conveyor (EQ1-04) and the fourth conveyor (EQ1-05).

[0038] Preferably, in order to ensure the accuracy of the X-ray scanning results, the speed of the scanning conveyor and the sorting conveyor (including the third conveyor (EQ1-04) and the fourth conveyor (EQ1-05)) must be consistent with the scanning rate of the X-ray machine, which can ensure that the position of each cargo is known and fixed when entering the X-ray machine. This enables the system to assign a unique number to each cargo and bind the number to the actual position of the cargo, thereby achieving accurate position tracking. If the two are not synchronized, the image may be distorted or blurred, affecting the security personnel's judgment of the internal structure of the item.

[0039] Furthermore, the speed monitoring unit is an encoder.

[0040] Preferably, the rotation of the conveyor drives the corresponding encoder to rotate, and the rotating encoder will output a pulse signal to the system controller. Since the encoder is installed on the drive shaft of the conveyor and rotates synchronously, the pulse signal can output a corresponding pulse signal according to the rotation speed of the conveyor.

[0041] Furthermore, step S1 specifically includes the following steps:

[0042] S1.1: Obtain pulse signals corresponding to the scanning conveyor and the sorting conveyor respectively based on the encoder;

[0043] S1.2: Calculate the rotation speeds of the scanning conveyor and the sorting conveyor respectively according to the frequency of the pulse signal change per unit time.

[0044] It should be noted that the expression of pulse detection speed S is:

[0045] S = (P / T)*60 / N;

[0046] Among them, P represents the number of pulses, which refers to the total number of pulses emitted by the encoder within a certain unit time; T represents the unit time, which refers to the time used to measure the total number of pulses; N represents the number of pulses per circle, which refers to the number of pulses emitted when the conveyor belt rotates one circle.

[0047] S2: Install displacement monitoring units on the scanning conveyor and the sorting conveyor respectively to obtain virtual position information of the goods.

[0048] Furthermore, the displacement monitoring unit is an encoder.

[0049] Preferably, the rotation of the conveyor drives the corresponding encoder to rotate, and the rotating encoder will output a pulse signal to the system controller. Since the encoder is installed on the drive shaft of the conveyor and rotates synchronously, the pulse signal can output a corresponding pulse signal according to the rotation speed of the conveyor.

[0050] Furthermore, step S2 specifically includes the following steps:

[0051] S2.1: Obtain pulse signals corresponding to the scanning conveyor and the sorting conveyor respectively based on the encoder;

[0052] S2.2: Calculate the real-time displacement of the scanning conveyor and the sorting conveyor respectively according to the number of changes in the pulse signal per unit time.

[0053] It should be noted that the calculation steps are:

[0054] Obtain the displacement of each conveyor and the number of changes in the pulse signal per unit time, and calculate the displacement of a single pulse based on the fact that the total displacement is the sum of all the individual displacements;

[0055] The initial encoder pulse count of each group of goods on each conveyor is obtained, and the real-time displacement of each group of goods is calculated in real time according to the change in the pulse count of each group of goods, so as to determine the actual position of each group of goods.

[0056] It should also be noted that the calculation formula is expressed as:

[0057] Single pulse displacement = displacement of one conveyor circle (mm) / number of pulses of one conveyor circle;

[0058] The real-time displacement of the cargo (mm) = total pulse amount × single pulse displacement;

[0059] The actual position of the goods (mm) = total pulse amount × single pulse displacement;

[0060] For example, the displacement of the conveyor when it rotates one circle (360 degrees) is 10 meters, and the number of pulse signals generated when it rotates one circle is 2000. Since the length of the conveyor is fixed, the displacement of the goods when it rotates one circle is constant, which can be further calculated:

[0061] 10(m)*1000=10000(mm);

[0062] 10000 (mm) / 2000 (pulse amount) = 5 (mm);

[0063] Therefore, the displacement of a single pulse is 5 (mm), that is, every time the encoder sends a pulse, the goods move 5 (mm).

[0064] In this way, the controller will know the real-time displacement of the current goods on the conveyor. The goods are constantly moving forward on the conveyor, and the total number of pulses of the system controller tracking the virtual position information is also constantly accumulating. The total number of pulses is multiplied by the displacement of a single pulse to obtain the actual position of the goods, thereby realizing the virtual position tracking of the goods.

[0065] S3: The image information of the goods on the scanning conveyor and the sorting conveyor is obtained respectively. The security inspection unit determines whether the goods are abnormal based on the image information and the virtual position information to ensure that the goods that pass through the sorting machine and arrive at the receiving platform meet the normal standards.

[0066] It should be noted that cargo image information includes cargo images produced by X-ray machines and real-time images captured by on-site cameras.

[0067] It should also be noted that the sorting machine is a swing wheel sorting machine (EQ1-06). A photoelectric sensor is installed at the front entrance of the swing wheel sorting machine (EQ1-06). When each piece of goods reaches this point, the photoelectric sensor will be triggered once, and the photoelectric sensor outputs a signal to the controller. First, only one piece of goods is placed on the entire conveyor during debugging. When the photoelectric sensor is triggered, the controller program will output the virtual position of the current piece of goods. Through multiple experiments, it is verified whether the current virtual position output by the controller is accurate. After the position debugging is set, it is put into operation. After that, when each piece of goods runs to the swing wheel sorting machine (EQ1-06), the controller finds the goods information at this position according to the signal of the photoelectric sensor. The controller determines the direction of movement of the swing wheel sorting machine (EQ1-06) according to the goods information at the current position. If the goods are safe and do not need to be inspected, the direction of the swing wheel sorting machine (EQ1-06) is controlled to be in the middle, and the goods flow to the cargo stacking platform. If the goods are suspicious and need to be inspected, the direction of the swing wheel sorting machine (EQ1-06) is controlled to the left to separate the goods to the return conveyor.

[0068] It should also be noted that after the goods enter the X-ray machine, the system controller will first encode the goods. The system controller will bind the current goods code and the current image generated by the X-ray machine. The goods image generated by the X-ray machine will be transmitted to the remote security inspection and judgment room in real time. The image of the goods can be seen on the remote terminal computer. Two monitors are installed on the remote terminal computer, one displays the image of the goods and the other displays the real-time picture recorded by the on-site camera. The security inspector judges judge whether the goods need to be inspected by observing the images and pictures on the two monitors.

[0069] It should also be noted that when the goods do not need to be inspected normally, the security inspector does not need to operate on the terminal computer. The terminal computer will send the cargo code and the information that no inspection is required to the on-site X-ray machine by default. After receiving the signal instruction, the on-site X-ray machine will transfer it to the on-site controller. The on-site controller will compare and bind the cargo code in the virtual position tracking according to the received cargo code. After binding, when the cargo is transmitted to the oscillating wheel sorter (EQ1-06), according to the cargo information of the virtual position tracking, the controller determines that no inspection is required. The position of the oscillating wheel sorter (EQ1-06) is set to direct pass, and the cargo is transmitted to the receiving platform and then boarded the flight.

[0070] It should also be noted that when the goods are suspicious and need to be inspected, the security inspector needs to click on the suspicious goods picture with the mouse to select it. At this time, the terminal computer will send the suspicious goods code and inspection information to the on-site X-ray machine. After receiving the signal instruction, the on-site X-ray machine will transfer it to the on-site controller. The on-site controller will compare and bind the goods code tracked by the virtual position according to the received goods code. After binding, when the goods are transmitted to the swing wheel sorter (EQ1-06), according to the goods information tracked by the virtual position, the controller determines that inspection is required. The swing wheel sorter (EQ1-06) is placed on the left, and the suspicious goods will be transmitted to the fifth conveyor (EQ1-07) and transported to the land side (outside the control area) through the sixth conveyor (EQ1-08) and the seventh conveyor (EQ1-09).

[0071] It should also be noted that after the suspicious goods are transported out of the control area, the security personnel will work with the logistics staff to open the suspicious packages for inspection. After the inspection confirms that there are no dangerous goods or prohibited items, they will be put back on the first conveyor (EQ1-01) and can enter the site again. Subsequent goods will continue to operate according to the above process.

[0072] Furthermore, the speeds of the first conveyor and the second conveyor are determined to ensure that the goods are instantaneously accelerated when they transition from the first conveyor to the second conveyor, thereby creating a first gap with the adjacent goods still on the first conveyor to ensure that the goods that pass first can complete the scanning task before the goods that pass later enter the scanning conveyor.

[0073] It should be noted that the first conveyor (EQ1-01) and the second conveyor (EQ1-02) are belt conveyors driven by servo motors, and their length and conveying speed can be designed according to actual needs. During normal transportation, they are adjusted according to the speed of the rear-end sorting line. The first conveyor (EQ1-01) and the second conveyor (EQ1-02) are set to form a supply section. The goods are placed manually in a front-to-back order (avoiding the goods being placed side by side) on the first conveyor (EQ1-01). The system automatically queues the goods, and automatically pulls the distance when the goods are transferred to the second conveyor (EQ1-02), and enters the subsequent scanning area in an orderly manner.

[0074] Example 2

[0075] This is the second embodiment of the present invention, which provides a cargo security inspection and sorting system, including a rotation speed monitoring and synchronization control module, a displacement monitoring and virtual position tracking module, an image information acquisition and analysis module, and an abnormal cargo processing module.

[0076] Among them, the speed monitoring and synchronization control module ensures that the transportation speeds of the scanning conveyor and the sorting conveyor are consistent, and monitors and adjusts the speeds of both through the encoder; the displacement monitoring and virtual position tracking module uses the encoder to calculate the rotation angle of the conveyor and the linear displacement of the goods, and generates the virtual position information of the goods; the image information acquisition and analysis module uses the X-ray machine to scan the goods and combine the virtual position information, and the security inspection unit determines whether the goods are abnormal; the abnormal goods processing module, when abnormal goods are detected, the system control unit guides the sorting machine to transfer the abnormal goods to the security inspection unit for further inspection according to its virtual position information.
