Description

Technical Field

[0001] The present invention relates to the field of information processing, and in particular to an airport baggage sorting method and system. Background Art

[0002] With the development of domestic economy, science and technology, domestic civil aviation has achieved unprecedented development in recent years. The number of civil aviation passengers has been increasing every year, and the baggage throughput of major airports has also reached a new height. The handling of airport baggage is a complex and huge task. In order to improve the efficiency of baggage sorting, major airports have built baggage sorting systems, which greatly improves the efficiency of baggage handling. At present, there are three main forms of domestic baggage sorting system terminals: a linear conveyor at the end, a baggage chute at the end, and a baggage carousel at the end. Among them, for the baggage sorting system with a baggage carousel at the end, after the baggage slides from the conveyor into the baggage carousel, the baggage handling staff around the baggage carousel manually identify the flight to which each piece of baggage belongs, and then take the baggage from the baggage carousel and load it into the baggage trailer and tow it away. However, the above-mentioned existing airport baggage sorting method and system are prone to baggage identification errors in the link of manually judging the flight to which the baggage belongs, resulting in sorting errors, and the efficiency of manual verification is also relatively low. Summary of the invention

[0003] The present application provides an airport baggage sorting method and system to improve the accuracy and efficiency of baggage sorting.

[0004] On the one hand, the present application provides an airport baggage sorting method, comprising:

[0005] The encoder acquires the conveying speed of the luggage relatively stationary on the luggage carousel in real time, and sends the conveying speed of the luggage to the single chip microcomputer;

[0006] The barcode scanner scans the luggage tag currently passing through the barcode scanner to obtain the identification of the luggage tag corresponding to the current luggage, and sends the identification of the luggage to the single-chip microcomputer;

[0007] The single chip microcomputer controls the display device to scroll and display the flight number of each piece of luggage at a speed equal to the conveying speed of the luggage;

[0008] The single chip computer uploads the identification of the current luggage to the cloud server and receives the flight number of the current luggage returned by the cloud server;

[0009] Under the control of the single chip microcomputer, the display device displays the flight number to which the current luggage belongs on the display screen of the display device, so that the luggage handler can take away the current luggage.

[0010] On the other hand, the present application provides an airport baggage sorting system, the system comprising a baggage carousel, an encoder, a barcode scanner, a single-chip microcomputer and a display device, the baggage carousel has a built-in motor, and the motor is connected to the encoder through a coupling:

[0011] The encoder is used to obtain the conveying speed of the luggage relatively stationary on the luggage carousel in real time, and send the conveying speed of the luggage to the single chip microcomputer;

[0012] The barcode scanner is used to scan the luggage tag currently passing through the barcode scanner to obtain the identification of the current luggage corresponding to the luggage tag, and send the identification of the luggage to the single-chip microcomputer;

[0013] The single chip microcomputer is used to control the display device to scroll and display the flight number of each piece of luggage at a speed equal to the conveying speed of the luggage, and to upload the identifier of the current luggage to the cloud server and receive the flight number of the current luggage returned by the cloud server;

[0014] The display device is used to display the flight number to which the current luggage belongs on the display screen of the display device under the control of the single chip microcomputer, so that the luggage handler can take away the current luggage.

[0015] From the technical solution provided by the present application, it can be seen that compared with the prior art that relies on manual judgment of the flight to which the luggage belongs, which is prone to cause luggage sorting errors and low verification efficiency, the present application obtains the luggage identification through a barcode scanner, and obtains the flight number to which the luggage belongs through processing by a cloud server. In other words, as two key links in luggage sorting, the luggage identification and the flight to which it belongs are obtained by computer program processing rather than manual judgment. The baggage handler only needs to identify the luggage corresponding to the flight number displayed on the display screen and take it away (this link is not prone to errors even if it is handled manually). Therefore, whether in terms of sorting accuracy or in terms of verification and sorting efficiency, the technical solution of the present application has been greatly improved compared with the prior art.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In this specification, qualifiers such as first and second may only be used to distinguish one element or action from another element or action, without requiring or implying any actual such relationship or order. Where circumstances permit, reference to an element or component or step (etc.) should not be interpreted as being limited to only one of the elements, components, or steps, but may be one or more of the elements, components, or steps, etc.

[0021] In this specification, for the convenience of description, the sizes of various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0022] This application proposes a method for sorting baggage at an airport, as shown in the attached Figure 1 As shown, the method mainly includes steps S101 to S105, which are described in detail as follows:

[0023] Step S101: the encoder acquires the conveying speed of the luggage relatively stationary on the luggage carousel in real time, and sends the conveying speed of the luggage to the single chip microcomputer.

[0024] The so-called luggage being stationary relative to the luggage carousel refers to the conveying speed of the luggage that is relatively stationary on the luggage carousel without sliding friction between the luggage and the luggage carousel, that is, the conveying speed of the luggage relative to other relatively stationary reference objects outside the luggage carousel. The conveying speed can be understood in a general sense. It should be noted that in the embodiment of the present application, the encoder is a rotary sensor that converts rotational displacement into a series of digital pulse signals, and is connected to the motor of the luggage carousel through a coupling. The encoder is mainly used to control the angular displacement by converting the pulse signal obtained by the rotational displacement. If the encoder is combined with a gear or a screw, it can also be used to measure the linear displacement. Specifically, in one embodiment of the present application, the encoder can obtain the conveying speed of the luggage that is relatively stationary on the luggage carousel in real time by: obtaining the speed of the motor of the luggage carousel in real time, and converting the speed of the motor into the linear speed of the luggage carousel as the conveying speed of the luggage according to the inherent mechanical transmission parameters of the luggage carousel and the speed of the motor of the luggage carousel as the conveying speed of the luggage.

[0025] Step S102: The barcode scanner scans the luggage tag currently passing through the barcode scanner to obtain the identification of the luggage tag corresponding to the current luggage, and sends the identification of the luggage to the single-chip microcomputer.

[0026] In the field of civil aviation, the so-called luggage tag is also called a luggage tag, which is a set of symbols that meet the IATA 1740C luggage coding requirements. The luggage tag has many forms, for example, it can be a one-dimensional barcode, or it can have a built-in RFID tag. In the embodiment of the present application, when the luggage tag is a one-dimensional barcode, the scanner can be a one-dimensional barcode scanner. Accordingly, the scanner can obtain the identification of the luggage tag corresponding to the current luggage by scanning the luggage tag currently passing through the scanner: when the one-dimensional barcode of the current luggage cuts the scanning line of the one-dimensional barcode scanner, the one-dimensional barcode scanner decodes the one-dimensional barcode of the current luggage and obtains the identification (ID) of the one-dimensional barcode corresponding to the current luggage, that is, whenever the one-dimensional barcode on the luggage passes through the scanning line before the one-dimensional barcode scanner, it forms a "cut" of the scanning line, and the one-dimensional barcode scanner obtains the one-dimensional barcode, and obtains the identification of the one-dimensional barcode corresponding to the current luggage after decoding it. Furthermore, considering its easy installation, barcode recognition can still be performed when the luggage is transported at a high speed, and it still has a high reading rate for damaged, contaminated and partially obscured barcodes. In the embodiment of the present application, the one-dimensional barcode scanner can use a scanner with model CLV320.

[0027] In another embodiment of the present application, when the luggage tag has an RFID tag built in, the scanner can be an RFID tag reader. Accordingly, the scanner can obtain the identification of the luggage tag corresponding to the current luggage by scanning the luggage tag currently passing through the scanner: when the RFID tag reader reads the RFID tag, it decodes the RFID tag to obtain the identification of the current luggage corresponding to the RFID tag. Further, as an embodiment of the present application, the optional model of the RFID tag reader is JT-8290W, which can accurately read RFID tags at a large distance, thereby meeting the requirements for obtaining luggage tags in the civil aviation field.

[0028] It should be noted that in the above-mentioned embodiment of the present application, the processor model of the single-chip microcomputer may be STM32F407ZET6, which has abundant I / O ports and peripheral communication interfaces, and can meet the needs of the technical solution of the present application.

[0029] Step S103: the single chip microcomputer controls the display device to scroll and display the flight number of each piece of luggage at a speed equal to the conveying speed of the luggage.

[0030] In the embodiment of the present application, the display device controlled by the single-chip microcomputer can be a scrolling LED screen. Since the single-chip microcomputer obtains the conveying speed of the luggage, it can control the display device to scroll and display the flight number of each piece of luggage at a speed equal to the conveying speed of the luggage. According to the technical scheme of steps S101 to S103, the conveying speed of the luggage and the display device scrolling and displaying the flight number of the luggage are synchronized. In other words, every time a piece of luggage L1 comes over, when its label is scanned by the barcode scanner, the flight number of the luggage L1 is displayed on the display device; when the next piece of luggage L2 comes over and its label is scanned by the barcode scanner, the display device scrolls down or moves left and right the flight number of the luggage L1 to display the flight number of the luggage L2, so that the display device is kept to display only the flight number of the current luggage.

[0031] Step S104: the single chip computer uploads the identification of the current luggage to the cloud server and receives the flight number of the current luggage returned by the cloud server.

[0032] In the embodiment of the present application, the single chip microcomputer can be connected to the cloud server through the network. Since the cloud server has a one-to-one correspondence between the identification of each piece of luggage and the flight number to which the luggage belongs, when the single chip microcomputer uploads the identification of the current luggage to the cloud server, the cloud server can obtain the flight number to which the current luggage belongs by querying, and then return the flight number to which the current luggage belongs to the single chip microcomputer.

[0033] Step S105: under the control of the single chip microcomputer, the display device displays the flight number to which the current luggage belongs on the display screen of the display device, so that the luggage handler can take the current luggage away.

[0034] Since the display device can clearly display the flight number to which the current baggage belongs (and only the flight number to which the current baggage belongs), baggage handlers only need to sort and transport the baggage according to the flight number, and do not need to check each piece of baggage, so the probability of error is low. It should be noted that even if the order of the baggage is disrupted, as long as the baggage rotates on the baggage carousel once and passes the barcode scanner again, the correct flight number of the baggage can be displayed on the display device again.

[0035] From the above attached Figure 1It can be seen from the example airport baggage sorting method that compared with the prior art that relies on manual judgment of the flight to which the baggage belongs, which is prone to baggage sorting errors and low verification efficiency, the present application obtains the baggage identification through a barcode scanner, and obtains the flight number to which the baggage belongs through processing by a cloud server. In other words, as two key links in baggage sorting, the baggage identification and the flight to which it belongs are obtained by computer program processing rather than relying on manual judgment. The baggage handler only needs to identify the baggage corresponding to the flight number displayed on the display screen and take it away (this link is not prone to errors even if it is handled manually). Therefore, whether in terms of sorting accuracy or in terms of verification and sorting efficiency, the technical solution of the present application has been greatly improved compared to the prior art.

[0036] Please refer to the attached Figure 2 , is an airport baggage sorting system provided by an embodiment of the present application, which may include a baggage carousel 201, an encoder 202, a barcode scanner 203, a single-chip microcomputer 204 and a display device 205, wherein the baggage carousel 201 has a built-in motor (not shown in the figure), the motor is connected to the encoder 202 through a coupling, and the single-chip microcomputer 204 is connected to a cloud server (not shown in the figure) through a network, as described in detail as follows:

[0037] The encoder 202 is used to obtain the conveying speed of the luggage relatively stationary on the luggage carousel 201 in real time, and send the conveying speed of the luggage to the single chip microcomputer 204;

[0038] The barcode scanner 203 is used to obtain the identification of the current luggage corresponding to the luggage tag by scanning the luggage tag currently passing through the barcode scanner 203, and send the identification of the luggage to the single chip microcomputer 204;

[0039] The single chip computer 204 is used to control the display device 205 to scroll and display the flight number of each piece of luggage at a speed equal to the speed of luggage conveyance, and to upload the identification of the current luggage to the cloud server and receive the flight number of the current luggage returned by the cloud server;

[0040] The display device 205 is used to display the flight number of the current luggage on the display screen of the display device under the control of the single chip computer 204, so that the luggage handler can take away the current luggage.

[0041] From the description of the above technical solution, it can be seen that compared with the prior art that relies on manual judgment of the flight to which the luggage belongs, which is prone to luggage sorting errors and low verification efficiency, the present application obtains the luggage identification through a barcode scanner, and obtains the flight number to which the luggage belongs through processing by a cloud server. In other words, as two key links in luggage sorting, the luggage identification and the flight to which it belongs are obtained by computer program processing rather than manual judgment. The baggage handler only needs to identify the luggage corresponding to the flight number displayed on the display screen and take it away (this link is not prone to errors even if it is handled manually).
