[0035] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0036] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of this disclosure.
[0037] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.
[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0039] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0040] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0041] Figure 1 This is a schematic flowchart illustrating a communication method according to an embodiment of the present disclosure. In some embodiments, the following communication method is performed by a control device in a CT device, including steps 11-12.
[0042] In step 11, from the first set of input / output ports of the CT device, select the i-th input / output port group that corresponds one-to-one with the i-th piece of information to be transmitted in the first set of information to be transmitted. N is the total number of messages to be sent in the first set of messages to be sent.
[0043] It should be noted that the i-th input / output port group includes one or K input / output ports, where K is a natural number greater than 1.
[0044] In step 12, based on the content of the i-th message to be sent, the state of each input / output port in the i-th input / output port group is controlled so that the i-th message to be sent is transmitted to the input / output port group corresponding to the i-th input / output port group on the transmission line of the baggage handling system.
[0045] It should be noted that each input / output port in the i-th input / output port group sends predetermined information when it is closed, and stops sending predetermined information when it is open.
[0046] In some embodiments, when the i-th input / output port group includes an input / output port, the input / output port group that corresponds one-to-one with the i-th input / output port group on the transmission line includes an input / output port.
[0047] When the i-th input / output port group includes K input / output ports, the input / output port group on the transmission line that corresponds one-to-one with the i-th input / output port group includes K input / output ports.
[0048] For example, such as Figure 2As shown, the first input / output port set of the CT device 21 includes three input / output port groups. The first input / output port group includes one input / output port, C1, corresponding to CT device state 1 and CT device state 2. The second input / output port group includes three input / output ports, C2, C3, and C4, corresponding to state 1 to state 6. The third input / output port group includes one input / output port, C5, corresponding to CT device state 3 and CT device state 4. The states of each input / output port are shown in Table 1.
[0049] Table 1
[0050] like Figure 2 As shown, input / output ports C1-C5 are also provided on transmission line 22. C1 of the CT device is electrically connected to C1 of the transmission line, C2 of the CT device is electrically connected to C2 of the transmission line, C3 of the CT device is electrically connected to C3 of the transmission line, C4 of the CT device is electrically connected to C4 of the transmission line, and C5 of the CT device is electrically connected to C5 of the transmission line. Therefore, the CT device 21 can exchange information with the transmission line 22.
[0051] In the communication method provided in the above embodiments of this disclosure, by controlling the state of each input / output port in the corresponding input / output port group according to the content of each message to be sent, the linkage between the CT equipment and the baggage handling system can be effectively realized.
[0052] Figure 3 This is a flowchart illustrating a communication method according to another embodiment of the present disclosure. In some embodiments, the following communication method is performed by a control device in a CT device, including steps 31-32.
[0053] In step 31, from the second set of input / output ports of the CT device, select the j-th input / output port group that corresponds one-to-one with the j-th message to be transmitted in the second set of messages to be transmitted. M represents the total number of messages to be sent in the second set of messages to be sent.
[0054] It should be noted that the j-th input / output port group includes one or P input / output ports, where P is a natural number greater than 1.
[0055] In some embodiments, when the j-th input / output port group includes one input / output port, the input / output port group corresponding one-to-one with the j-th input / output port group on the transmission line includes one input / output port. When the j-th input / output port group includes P input / output ports, the input / output port group corresponding one-to-one with the j-th input / output port group on the transmission line includes P input / output ports. For example, P is 4.
[0056] In step 32, based on the content of the j-th message to be sent, the state of each input / output port in the j-th input / output port group is controlled so as to send the second message to be sent to the input / output port group on the transmission line that corresponds one-to-one with the j-th input / output port group.
[0057] It should be noted that each input / output port in the j-th input / output port group sends predetermined information when it is closed, and stops sending predetermined information when it is open.
[0058] For example, such as Figure 4 As shown, the CT device 41 and the transmission line 42 communicate through input / output ports. If the CT device 41 is used as an EDS (Explosive Detection System), the I / O (input / output) signals output by the CT device 41 are shown in Table 2.
[0059] Table 2
[0060] Table 3
[0061] In some embodiments, such as Figure 5 As shown, the CT device 51 receives baggage barcodes (e.g., IATA codes, etc.) and package identifiers (BagIDs) from serial port 521 on transmission line 52 via serial port 511. Next, the first baggage detection result is sent to serial port 521 via serial port 511, wherein the first baggage detection result includes baggage barcodes, package identifiers, and automatic image interpretation results.
[0062] When the CT equipment has automatic image interpretation capability, serial port 511 sends the interpretation result to serial port 521.
[0063] In the case of manual image interpretation, the CT device 51 sends the interpretation results to the serial port 522 in the transmission line 52 via the serial port 512.
[0064] In some embodiments, such as Figure 5 As shown, the CT device 51 receives the baggage barcode (e.g., IATA code) and the mandatory diversion package identifier (BagID) from the serial port 522 on the transmission line 52 via the serial port 512. Next, the second baggage detection result is sent from the serial port 512 of the CT device 51 to the serial port 522, wherein the second baggage detection result includes the baggage barcode, package identifier, and manual image interpretation result.
[0065] In some embodiments, such as Figure 6As shown, the predetermined controller port 611 of the CT device 61 interacts with the Industrial Ethernet Protocol PN (PROFINET) coupler 63 so that the PN coupler 63 sends the information sent by the predetermined controller port 611 to the predetermined controller port 621 on the transmission line 62, and sends the information sent by the predetermined controller port 621 to the predetermined controller port 611.
[0066] For example, controller ports 611 and 621 are designated as PLC (Programmable Logic Controller) ports.
[0067] It should be noted that by using the PN coupler 63, network IP isolation between the CT equipment and the transmission line can be effectively achieved. Furthermore, long-distance communication is possible via PN communication. For example, it can reach 100m using ITP (Industrial Shielded Twisted Pair) cable, and several kilometers or even tens of kilometers using fiber optic transmission.
[0068] In some embodiments, such as Figure 6 As shown, the CT device 61 interacts with the intelligent image review system 64 through the TCP (Transmission Control Protocol) port 612 to obtain the CT scan image review results of the intelligent image review system 64.
[0069] Therefore, the CT scan image review results provided by the intelligent image review system 64 can be sent to the transmission line 62 via the PN coupler 63.
[0070] In some embodiments, such as Figure 7 As shown, the DP (Distributed Peripheral) port 71 of the CT device 71 interacts with the DP port 721 on the transmission line 72 via PROFIBUS (Process Field Bus).
[0071] It should be noted that long-distance communication can also be achieved through DP communication. For example, at a baud rate of 500K, the maximum transmission distance is 400m, and at lower rates, it can even reach 1000m.
[0072] In some embodiments, such as Figure 7 As shown, the CT device 71 interacts with the intelligent image review system 73 through TCP port 712 in order to obtain the CT scan image review results of the intelligent image review system 73.
[0073] Therefore, the CT scan image review results provided by the intelligent image review system 73 can be sent to the transmission line 72 through the DP port 711.
[0074] In some embodiments, such as Figure 8 As shown, the control device 811 in the CT equipment 81 can directly interact with the intelligent image review system 83 via the TCP / IP protocol to obtain the CT scan image review results from the intelligent image review system 83. Next, the control device 811 sends the CT scan image review results to the transmission line 82 via the TCP / IP protocol.
[0075] In some embodiments, the control device 811 monitors and manages the CT equipment based on information sent by the intelligent image review system 83.
[0076] For example, the control device 811 controls the CT equipment 81 to turn on and off, or to go into sleep or wake up, based on the information sent by the intelligent image review system 83, and can also collect the relevant status of the CT equipment 81 in real time.
[0077] Figure 9 This is a schematic diagram of the structure of a control device according to an embodiment of the present disclosure.
[0078] like Figure 9 As shown, the control device 90 is presented in the form of a general-purpose computing device. The control device 90 includes a memory 91, a processor 92, and a bus 93 connecting different system components.
[0079] The memory 91 may include, for example, system memory, non-volatile storage media, etc. System memory may store, for example, an operating system, application programs, a boot loader, and other programs. System memory may include volatile storage media, such as random access memory (RAM) and / or cache memory. Non-volatile storage media may store, for example, instructions for a corresponding embodiment of at least one model training method being executed. Non-volatile storage media include, but are not limited to, disk storage, optical storage, flash memory, etc.
[0080] The processor 92 can be implemented using a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete hardware components such as discrete gates or transistors. Accordingly, each module, such as the acquisition module, the calculation module, and the adjustment module, can be implemented by executing instructions in the central processing unit (CPU) running memory to perform the corresponding steps, or by implementing dedicated circuits that perform the corresponding steps.
[0081] For example, processor 92 is configured for memory-based instruction execution implementation such as Figure 1 ,3 The method involved in any of the embodiments.
[0082] Bus 93 can use any of the various bus architectures. For example, bus architectures include, but are not limited to, the Industry Standard Architecture (ISA) bus, the Micro Channel Architecture (MCA) bus, and the Peripheral Component Interconnect (PCI) bus.
[0083] The interfaces 94, 95, and 96 of the control device 90, as well as the memory 91 and processor 92, can be connected via bus 93. Input / output interface 94 provides a connection interface for input / output devices such as monitors, mice, and keyboards. Network interface 95 provides a connection interface for various networked devices. Storage interface 96 provides a connection interface for external storage devices such as floppy disks, USB flash drives, and SD cards.

[0093] In some embodiments, the CT device 100 further includes an emergency stop device 109 for sending an emergency stop signal to the transmission line in the event of an emergency in the CT device 100.
[0094] For example, the emergency stop device 109 is a dry contact device so that it can still work when the CT equipment is powered off.
[0095] Figure 11 This is a schematic diagram of the structure of a communication system according to an embodiment of the present disclosure.
[0096] like Figure 11 As shown, the communication system includes a CT device 111, a baggage handling system transmission line 112, a PN coupler 113, and centralized image interpretation systems 114 and 115.
[0097] It should be noted here that the CT equipment 111 is... Figure 10 The CT device shown in any of the embodiments.
[0098] For the sake of simplicity, in Figure 11 In the diagram, only one input / output port 1112 is shown in the CT device 111. Those skilled in the art will understand that the CT device 111 may include multiple input / output ports, and may be divided into different sets of input / output ports as needed.
[0099] Similarly, in Figure 11 In the diagram, only one input / output port 1121 is shown in the transmission line 112. Those skilled in the art will understand that the transmission line 112 may include multiple input / output ports and may be divided into different sets of input / output ports as needed, so as to correspond one-to-one with the set of input / output ports in the CT device 111.
[0100] like Figure 11As shown, under the control of the control device 1111, the input / output port 1112 in the CT device 111 interacts with the input / output port 1121 in the transmission line 112; the first serial port 1113 in the CT device 111 interacts with the first serial port 1122 in the transmission line 112; the second serial port 1114 in the CT device 111 interacts with the second serial port 1123 in the transmission line 112; the PLC port 1115 in the CT device 111 interacts with the PLC port 1124 in the transmission line 112 through the PN coupler 113; the DP port 1116 in the CT device 111 interacts with the DP port 1125 in the transmission line 112; and the TCP port 1117 in the CT device 111 interacts with the centralized image interpretation system 114 through the TCP / IP protocol.
[0101] It should be noted that the PN coupler 113 sends the information sent by the PLC port 1115 of the CT device 111 to the PLC port 1124 in the transmission line 112, and sends the information sent by the PLC port 1124 in the transmission line 112 to the PLC port 1115 of the CT device 121.
[0102] It should also be noted that the centralized image interpretation system 114 reviews the CT scan images sent by TCP port 1117 in the CT device 111, and sends the review results of the CT scan images to TCP port 1117 in the CT device 111.
[0103] In addition, such as Figure 11 As shown, the control device 1111 interacts with the centralized image interpretation system 115 via the TCP / IP protocol, and can also interact with the transmission line 112 via the TCP / IP protocol.
[0104] It should also be noted that the centralized image analysis system 115 reviews the CT scan images sent by the control device 1111 and sends the review results of the CT scan images to the control device 1111.
[0105] In some embodiments, such as Figure 11 As shown, in some embodiments, the CT device 111 further includes an emergency stop device 1118 for sending an emergency stop signal to the transmission line 112 in the event of an emergency in the CT device 111. The transmission line 112 further includes an emergency stop device 1127 for sending an emergency stop signal to the CT device 111 in the event of an emergency in the transmission line 112.
[0106] For example, emergency stop device 1118 is a dry contact device so that it can still operate when the CT equipment is powered off. Emergency stop device 1127 is a dry contact device so that it can still operate when the transmission line is powered off.
