Checked baggage handling method and checked baggage handling system {METHOD AND SYSTEM FOR PROCESSING BAGGAGE FOR CONSIGNATION IN AIRPORT}

The present invention relates to a method of handling checked baggage at an airport, and more particularly, to an increase in baggage throughput and improvement in accuracy of baggage reading through a simplification of a baggage handling procedure transferred through a conveyor line.

The technology behind the present invention is disclosed in the following documents.

1) Japanese publication number: 2001-233440 (2001.08.28), "Automatic baggage sorting system"

2) Japanese Publication No.: Japanese Unexamined Patent Application Publication No. Hei 5-116735 (1993.05.14), "Tracking Control Method of Baggage Transfer Line"

3) Japanese registration number: 3268525 (2002.01.18), "Airport baggage transfer system"

According to the baggage handling process at the airport, when baggage is loaded from the Check In counter to the Scale Conveyor and Input Conveyor, the entered baggage is transported to the Collection Conveyor while x-raying. The device reads the baggage and transfers the read baggage to a carousel where the departure baggage is loaded on a belt conveyor.

As such, since the existing baggage handling system consists of several types of conveyors and operates independently of each other, it takes a considerable amount of time (up to 14 minutes) to handle the sorting of input baggage and transfer to the carousel.

In addition, the existing baggage handling system directly searches for items that violate the security level in the X-ray image of the baggage, so the efficiency of the baggage reading procedure may decrease during the opening search, and there may be baggage that exceeds the permitted specifications. In this case, it may be difficult to meet the processing speed you are trying to achieve because the overall processing flow is slowed because it interferes with the processing of other normal baggage being conveyed to the conveyor.

Particularly in a small airport, since it is difficult to install a long conveyor, it is necessary to read baggage within a short time, but there may be limitations in accurately reading various types of baggage owned by ordinary passengers.

An embodiment of the present invention aims to increase the throughput of baggage per hour and improve the accuracy of baggage reading by constructing a simplified baggage handling system that can be applied in a medium-sized or smaller airport.

A method of handling checked baggage according to an embodiment of the present invention includes the steps of obtaining a first image of the baggage put on a conveyor line, and classifying the baggage according to a first reading result of the first image. And, injecting the baggage to which the abnormal tag has been assigned according to the classification, to a re-search line branching from the conveyor line, and obtaining a second image of the baggage to which the abnormal tag has been added to the re-search line. And transferring the baggage from which the abnormal tag is removed to a designated carousel according to a second reading result of the second image.

In addition, the checked baggage handling system according to an embodiment of the present invention comprises an acquisition unit for acquiring a first image of baggage to be put into a conveyor line, and classification of the baggage according to a first reading result of the first image. A classification unit, an input unit for inserting the baggage with an abnormal tag according to the classification into a rescan line branching from the conveyor line, and a product obtained for the baggage to which the abnormal tag is inserted into the rescan line. 2 According to the second reading result of the image, it may include a processing unit for transferring the baggage from which the abnormal tag is removed to a designated carousel.

According to an embodiment of the present invention, through a simplified baggage handling system that can be applied in a medium-sized or smaller airport where it is difficult to install a long conveyor line, it is possible to shorten the handling time of baggage and improve the accuracy of baggage reading. .

According to an embodiment of the present invention, a separate reading terminal is not provided on the conveyor line by transmitting all X-ray images of the baggage to the central reading terminal away from the conveyor line, so that the baggage reading is processed by the central reading terminal. By doing so, you can simplify the baggage handling system.

According to an embodiment of the present invention, a simplified baggage handling system can be constructed so that classification of baggage for re-inspection and re-insertion of normal baggage that has been re-inspected can be easily handled on a conveyor line with a limited distance.

According to an embodiment of the present invention, by introducing baggage classified as abnormal according to reading from a central reading terminal to a re-inspection line branching from the conveyor line, the processing flow of the conveyor line is not delayed while re-inspecting the abnormal baggage. And it is possible to speed up the opening search.

According to an embodiment of the present invention, by moving baggage that is normally reclassified by processing in a re-inspection line to the conveyor line through a re-introduction line connected to the re-inspection line, the re-introduction of normal baggage is facilitated. can do.

Referring to FIG. 1, the checked baggage handling system 100 may include a conveyor line 110, a re-search line 120, and a re-entry line 130.

The conveyor line 110 may serve to transfer normal baggage among baggage input from the check-in counter to the departure carousel 140.

The conveyor line 110 may include a first conveyor line 111, a second conveyor line 112 and a horizontal sorter (not shown).

For example, the first conveyor line 111 may be implemented as a collection conveyor, the second conveyor line 112 may be implemented as a belt conveyor, and the horizontal sorter is a first conveyor line 111 and a second conveyor line 112. ) Can be installed between.

The checked baggage handling system 100 directs the horizontal sorter to the second conveyor line 112, so that normal baggage among the baggage inputted to the first conveyor line 111 is departed through the second conveyor line 112. 140).

The checked baggage handling system 100 photographs the baggage inputted to the first conveyor line 111 with an X-ray apparatus, and transmits the photographed image (first image) to a remote central reading terminal (not shown), It is possible to classify whether the baggage is normal baggage or abnormal baggage according to the first reading result input from the central reading terminal.

The checked baggage handling system 100 changes the horizontal sorter to face the rescan line 120 for re-inspection of baggage classified as abnormal baggage, and is inserted from the first conveyor line 111 to the rescan line 120. I can.

The checked baggage handling system 100 may display an image (second image) photographed with an X-ray apparatus for the baggage put into the re-scan line 120 on an unopened search terminal (not shown) provided in the re-scan line 120. have.

At this time, the checked baggage handling system 100, when an object estimated to be dangerous or explosive is input as being included in the image as a result of the first reading, transfers the baggage to the unopened search desk 121 provided in the rescan line 120. The image is taken after the object is removed by a search agent by automatic discharging, and if the baggage is input as a result of the first reading that is outside the specified standard, the baggage is automatically discharged to the unopened search counter 121 Thus, the image can be photographed after the luggage is changed in the shape of the baggage being placed by the search agent.

The checked baggage handling system 100 may remove the abnormal tag from the baggage according to the second read result input from the unpacking search terminal.

If the abnormal tag is not removed, the checked baggage handling system 100 may automatically discharge the baggage back to the unopening search table 121.

When the abnormal tag is removed, the checked baggage handling system 100 may move the baggage to the reload line 130 and display the second read result on the terminal (MES) provided on the reload line 130. have.

Checked baggage handling system 100, if the second reading result displayed on the terminal is not related to any one of detection of dangerous goods, detection of explosives, exceeding a predetermined standard, and not obtaining an image, the baggage on the re-entry line is Can be confirmed as baggage.

The checked baggage handling system 100 drives the reload line 130 as it is determined as normal baggage by the terminal to depart the normal baggage on the reload line 130 through the second conveyor line 112 It can be transferred to the carousel 140.

In this way, the checked baggage handling system 100 separates from the conveyor line 110, a re-inspection line 120 for re-inspecting the baggage, and a re-introduction line for re-introducing the re-inspected normal baggage to the conveyor line 110 ( 130), it is possible to accurately read and process various types of baggage within a short time in airport facilities where it is difficult to install the conveyor line 110 for a long time.

2 is a block diagram showing the internal configuration of a checked baggage handling system according to an embodiment of the present invention.

Referring to FIG. 2, the checked baggage handling system 200 according to an embodiment of the present invention includes an acquisition unit 210, a classification unit 220, an input unit 230, a processing unit 240, and a database 250. It can be configured to include.

The acquisition unit 210 acquires a first image of baggage that is put into the conveyor line.

For example, whenever the acquisition unit 210 acquires an image of the baggage from an X-ray device, it recognizes the identification information from the barcode attached to the baggage with an Auto Tag Reader (ATR), and recognizes the image and the image. An abnormal tag assigned according to a result of reading about may be stored in the database 250 in correspondence with the identification information.

Here, the abnormal tag may be assigned to a baggage requiring an opening inspection so that it is distinguished from a normal baggage capable of being mounted on an aircraft.

For example, referring to FIG. 4, the acquisition unit 210 acquires a first image of the baggage inputted to the first conveyor line 401 from the X-ray device 418, and then the X-ray device 418 The identification information of the baggage can be recognized through the ATR 417 installed at the rear end of the terminal, and the first image and identification information can be transmitted to a remote central reading terminal to request reading.

The central reading terminal is implemented as a remote reading PC separated from the conveyor line, and through the first image, it reads whether there is an item that is estimated to be dangerous or explosive in the baggage, whether the baggage exceeds a specified standard, and the reading result You can enter the button according to.

The classification unit 220 classifies the baggage according to a first read result of the first image.

That is, the classification unit 220 may classify baggage that can be loaded on an aircraft as a normal baggage according to the first reading result, and may assign an abnormal tag to a baggage requiring a separate opening inspection to be distinguished from normal baggage.

According to the first reading result input from the central reading terminal, the classification unit 220 assigns an abnormal tag to baggage that is not classified as a normal baggage, and provides identification information of the baggage to which the abnormal tag is assigned, according to the first reading result. It can be stored in the database 250 together with the classification.

For example, the classification unit 220 includes items that are estimated to be dangerous goods (e.g.,'spray more than a certain number','liquids','firearms','knife','drugs', etc.) through the first image. If it reads, it can classify the baggage as'suspect baggage' and give it an abnormal tag.

In addition, when the classification unit 220 reads that the item estimated to be an explosive is included through the first image, the baggage is classified as'ETD baggage' and may be assigned an abnormal tag.

In addition, if no reading result for the first image is input within a selected time (eg, '12 seconds'), the classification unit 220 may classify the baggage as'excessive time baggage' and assign an abnormal tag. have.

In addition, the classification unit 220 may classify baggage that has not been read by the central reading terminal because an image has not been photographed by the X-ray device, as'unexpressed baggage that has not been read image', and may assign an abnormal tag.

In addition, when the baggage is read as exceeding the predetermined standard through the first image, the classification unit 220 may classify the baggage as'excess standard baggage' and assign an abnormal tag.

The input unit 230 inserts the baggage to which the abnormal tag has been assigned according to the classification, to a re-search line branching from the conveyor line.

The conveyor line may include a first conveyor line (eg,'collective conveyor') into which the baggage is put, and a second conveyor line (eg,'belt conveyor') transferring normal baggage to the carousel. .

The acquisition unit 210 transmits the first image acquired from the X-ray device in the first conveyor line to a remote central reading terminal, and the first image input from the central reading terminal that reads the first image. 1 When an abnormal tag is given to the baggage according to the read result, the input unit 230 may change the direction of the horizontal sorter on the first conveyor line toward the second conveyor line to face the rescan line. .

For example, referring to FIG. 4, the input unit 230 changes the horizontal sorter 403 set to face the second conveyor line 402 from the first conveyor line 401 to face the rescan line 404 , Baggage with an abnormal tag may be put into the re-search line 404 instead of the second conveyor line 402.

The input unit 230 may illuminate a tower light installed in the horizontal sorter in a color according to the first reading result in conjunction with the insertion of the abnormal tag attached baggage into the re-search line.

For example, the input unit 230 lights up the tower light in'blue' related to an image not acquired,'green' related to exceeding the reading time, or lights up in'red' related to detection of dangerous objects. Or, it may be lit in'yellow' associated with explosive detection, or if it is related to exceeding a predetermined standard, a plurality of colors may be flashed and flashed.

The processing unit 240 removes the abnormal tag and designates the baggage from which the abnormal tag has been removed according to a second read result of the second image obtained for the baggage to which the abnormal tag is applied to the re-search line. Transfer to the carousel.

For example, when the tower light is lit in'blue' related to an image not being acquired or'green' related to an exceeded reading time, the acquisition unit 210 displays the second image as an X-ray in the rescan line. It can be obtained from the device and displayed on the opening search terminal. The processing unit 240 may determine whether to remove the abnormal tag for the baggage that is reclassified according to a second reading result input from the opening search terminal that has read the second image.

For example, referring to FIGS. 3 and 4, when the tower light 405 is lit in blue or yellow, it is necessary to discharge the baggage from the processing unit 240 to the unopened search table 308 provided in the re-scan line 307 Without, the acquisition unit 210 may display a second image photographed by the X-ray apparatus 312 on the rescan line 307 on the unopened search terminal 406. The classification unit 220 receives the result of reading whether an item estimated to be dangerous or explosive is included through the second image from the opening search terminal 406 and whether it meets a predetermined standard, and receives a second image for the second image. Baggage can be reclassified according to the reading result.

As another example, when the tower light is lit in'red' related to detection of dangerous substances or'yellow' related to detection of explosives, the processing unit 240 determines the position of the object estimated to be dangerous or explosive in the second image. The object may be removed from the baggage by discharging the baggage to be displayed on the unopened search terminal and to which the abnormal tag has been assigned, to an unopened retrieval zone provided in the re-search line.

For example, referring to FIGS. 3 and 4, when the tower light 405 is lit in red, the processing unit 240 automatically discharges the baggage to the unopened search table 308 provided in the rescan line 307, and is assumed to be a dangerous material. By displaying the location of the item in a pink frame on the opening search terminal 406, the dangerous item can be removed from the baggage by the security screening agent (passenger) who has confirmed this.

The acquisition unit 210 acquires a second image of the baggage removed from the dangerous substance from the X-ray apparatus 312 and displays it on the opening search terminal 406, and displays the second image in the opening search terminal 406. Through this, it is possible to read whether the dangerous goods have been removed.

When the classification unit 220 inputs that the dangerous goods have been removed by the opening search terminal 406 that has read the second image, the baggage can be reclassified as normal baggage. In this case, the processing unit 240 Can be removed.

In addition, the classification unit 220 may reclassify the baggage as ETD baggage if the dangerous article has been removed by the unopened search terminal 406 that read the second image, but is input as containing an article that is estimated to be another explosive. .

As described above, when it is read that an object estimated to be a dangerous or explosive material is included in the image, the processing unit 240 may transmit the identification information of the baggage discharged to the unopened search zone provided in the rescan line to the security personnel.

As another example, when the tower light i) flashes in multiple colors associated with exceeding the specified standard, the processing unit 240 discharges the baggage with the abnormal tag attached to the unopened search area provided in the re-scan line, and places the baggage. You can have the shape change.

For example, referring to FIGS. 3 and 4, when the tower light 405 flashes in various colors, the processing unit 240 automatically discharges the baggage to the unopened search table 308 provided in the re-scan line 307 Then, after processing so that the shape of the baggage is changed by the security screening agent, and the result of reading as conforming to the specified standard through the second image obtained from the X-ray device is input from the opening search terminal, the classification unit ( 220) can reclassify baggage as normal baggage so that abnormal tags are removed.

In addition, the processing unit 240 may ii) separate the attached baggage from the sorting position, ii) when the loaded baggage has a deformed shape, iii) an ATR tracking error in which the number of baggage recognized by the ATR does not match. In the event that the baggage inserted in the X-ray device is discharged with the following baggage, even if the tower light flashes in multiple colors associated with any of the cases, the baggage is discharged to the opening screening area. This laid shape can be corrected.

As an example, the processing unit 240 moves the baggage from which the abnormal tag has been removed from the rescan line to a reload line, and when the baggage that has moved to the reload line is determined as normal baggage, drives the reload line. , Baggage on the reloading line may be transferred to the carousel through the conveyor line connected to the reloading line.

At this time, the acquisition unit 210 transmits the second reading result to a terminal provided on the re-input line (for example, a'barcode manual detection MES terminal'), and the processing unit 240 transmits the second reading result to the terminal displayed on the terminal. If the read result is not associated with any one of detection of dangerous goods, detection of explosives, exceeding a predetermined standard, and not obtaining an image, the baggage on the re-entry line can be determined as normal baggage.

For example, referring to FIG. 4, the processing unit 240 may move baggage that is normally reclassified as a result of reading by the unpacking search terminal 406 from the rescan line 404 to the reinsertion line 407.

The acquisition unit 210 may recognize the barcode of the baggage placed on the re-entry line 407 through the MES terminal 408 and display the second reading result of the baggage on the MES terminal 408.

If the second reading result is not associated with any one of detection of dangerous goods, detection of explosives, exceeding a predetermined standard, and not obtaining an image, the processing unit 240 operates the re-input line 407 through the MES terminal 408, Baggage placed on the reloading line 407 may be reloaded into the second conveyor line 402.

Here, the MES terminal 408 is a device for re-inserting baggage, and may be equipped with a barcode re-entry function, a read result display function, and a re-entry line 407 (eg, re-entry conveyor) driving function.

Thereafter, the processing unit 240 may transfer the normal baggage reloaded by the second conveyor line 402 to the departure carousel.

As described above, according to an embodiment of the present invention, through a simplified baggage handling system that can be applied in a medium-sized or smaller airport where it is difficult to install a long conveyor line, the baggage handling time is shortened and the accuracy of baggage reading is improved. I can make it.

According to an embodiment of the present invention, a separate reading terminal is not provided on the conveyor line by transmitting all X-ray images of the baggage to the central reading terminal away from the conveyor line, so that the baggage reading is processed by the central reading terminal. By doing so, you can simplify the baggage handling system.

According to an embodiment of the present invention, a simplified baggage handling system can be constructed so that classification of baggage for re-inspection and re-insertion of normal baggage that has been re-inspected can be easily handled on a conveyor line with a limited distance.

According to an embodiment of the present invention, by introducing baggage classified as abnormal according to reading from a central reading terminal to a re-inspection line branching from the conveyor line, the processing flow of the conveyor line is not delayed while re-inspecting the abnormal baggage. And it is possible to speed up the opening search.

According to an embodiment of the present invention, by moving baggage that is normally reclassified by processing in a re-inspection line to the conveyor line through a re-introduction line connected to the re-inspection line, the re-introduction of normal baggage is facilitated. can do.

3 is a diagram showing a layout of a checked baggage handling system according to an embodiment of the present invention.

3, the checked baggage handling system 300 includes a check-in conveyor 301, a first conveyor line 302, an X-ray device 303, an Auto Tag Reader (ATR) 304, and a central reading terminal ( 305, a horizontal divider (306), a rescan line 307, an X-ray device 312, an opening search table 308, a reload line 309, a second conveyor line 310, and a starting carrot. It can be configured to include the cell 311.

Each of the check-in conveyor 301, the first conveyor line 302, the rescan line 307, the reload line 309, and the second conveyor line 310 may be designed to have a width of about 100 cm.

The check-in conveyor 301 may play a role of injecting the baggage attached with a barcode (Tag) to the first conveyor line 302 by an operation panel (reservation system) at a check-in counter in the airport.

Check-in conveyor 301 may be composed of a scale conveyor (Scale Conveyor) and an input conveyor (Input Conveyor).

Scale conveyors can detect baggage carried by passengers, measure the weight, and determine whether the baggage meets the specifications.

The input conveyor may input the weight-measured baggage into the first conveyor line 302 according to an input of a foot switch.

The first conveyor line 302 may be implemented as, for example, a collection conveyor, and is driven without stopping in the direction in which the starting carousel 311 is located, so that the luggage placed on the first conveyor line 302 is departed from the carousel. Can be transferred to (311).

A plurality of photo sensors ('6') and encoder sensors are installed on the first conveyor line 302 at regular intervals, so that baggage that exceeds a predetermined standard can be primarily classified among transported baggage.

The checked baggage handling system 300 captures the baggage inputted to the first conveyor line 302 with the X-ray device 303, and then identifies the acquired baggage by recognizing the barcode attached to the baggage with the ATR 304. The information can be transmitted to the remote central reading terminal 305 together with the captured image to request reading.

The central reading terminal 305 is implemented as a remote reading PC separated from the first conveyor line 302, and can read whether an object estimated to be dangerous or explosive is included in the photographed image, or whether it exceeds a predetermined standard. I can.

In this way, the checked baggage handling system 300 allows the reading of the baggage conveyed by each of the first conveyor lines 302 to be performed at the central reading terminal 305 away from the first conveyor line 302, so that the reading procedure is performed. Therefore, it is possible to increase the processing efficiency by not obstructing the processing flow of baggage.

The checked baggage handling system 300 classifies the baggage for which the pass button is input within a selected time period (12 seconds) from the central reading terminal 305 as normal baggage, and determines the normal baggage that has not been assigned an abnormal tag as a first conveyor. It can move from line 302 to second conveyor line 310.

The second conveyor line 310 may be implemented as, for example, a belt conveyor, and is driven independently from the first conveyor line 302 to depart from the normal baggage placed on the second conveyor line 310. Can be transferred to (311).

Meanwhile, the checked baggage handling system 300 may classify as suspicious baggage and assign an abnormal tag to baggage that has been read from the central reading terminal 305 as including an article estimated to be dangerous.

In addition, the checked baggage handling system 300 classifies baggage read from the central reading terminal 305 as containing an item that is estimated to be an explosive in the baggage image as classified baggage (ETD baggage) according to the security level, and uses abnormal tags. Can be given.

At this time, the checked baggage handling system 300 may classify baggage for which no reading result is input within a selected time period (12 seconds) from the central reading terminal 305 as baggage exceeding the time limit, and may assign an abnormal tag. .

In addition, the checked baggage handling system 300 classifies baggage for which an image is not displayed on the central reading terminal 305 because an image is not captured by the X-ray device 303 as unexpressed baggage, and an abnormal tag Can be given.

The checked baggage handling system 300 changes the horizontal sorter 306 that was facing the second conveyor line 310 to face the rescan line 307 in the case of baggage that has been assigned an abnormal tag, so that the first conveyor line 302 ) Can be put into the branched re-search line 307, at this time, the tower light installed in the horizontal sorter 306 can be lit in a color related to the read result of the put baggage.

For example, the checked baggage handling system 300 illuminates the tower light in red indicating suspicious baggage, yellow indicating ETD baggage, green indicating exceeding the time limit, blue indicating no read image, or flashing multiple colors. May indicate excess.

The double-checked baggage handling system 300 automatically discharges the inserted baggage to the opening checkpoint 308 when the tower light is lit in red (suspicious baggage), yellow (ETD baggage), and blinking (exceeding the standard), and security personnel By removing the items that are assumed to be dangerous or explosives from the baggage, the baggage can be disposed of to change the shape.

The checked baggage handling system 300 transmits the image taken by the X-ray device 312 for the processed baggage to the unopened search terminal (recheck computer), and from the baggage according to the result of reading by the unopened search terminal. It is possible to determine whether to remove abnormal tags.

At this time, the checked baggage handling system 300 does not dispose of the baggage to the unopened checkpoint 308 when the tower light is lit in green (exceeding the time limit) or blue (reading image not displayed), and an X-ray device ( The image of the baggage taken with 312) can be transmitted to the opening search terminal to request reading.

The checked baggage handling system 300 moves the baggage from which the abnormal tag is removed according to the result of reading from the rescan line 307 to the reload line 309 from the rescan line 307, and It may be re-introduced to the second conveyor line 310 according to the drive.

At this time, the checked baggage handling system 300 displays the second reading result of the baggage placed on the reload line 309 on the terminal (MES terminal for manual barcode detection) provided on the reload line 309, and is displayed on the terminal. If it is determined as normal baggage according to the reading result, the baggage can be reloaded by driving the reloading line 309.

Depending on the embodiment, the checked baggage handling system 300 may further include a PLC system (not shown) configured with dual CPUs.

The PLC system is connected to the Remote I/O device by Profibus DP communication and can receive signals from the operation panel, and the X-ray devices (303, 312) are connected by MODBUS RTU, and the ATR (304) is Profibus. It is interfaced by and can be connected to other HMIs by Ethernet.

The checked baggage handling system 300 applies AT-class X-ray security screening to the departure baggage, and may search all departure baggage with a security screening device (X-ray).

The checked baggage handling system 300 transmits all images captured by the X-ray device to a multi-workstation (central reading terminal) built in a reading room dedicated to security search, and determines whether or not abnormal baggage (ineligible and re-scanned). , You can store and manage data on abnormal baggage.

If it is determined as suspicious baggage at the multi-workstation, the checked baggage handling system 300 can automatically separate the baggage with a diverter device (horizontal sorter) at the rear end of the X-ray device in the conveyor line to perform re-scanning. , Suspected baggage that violates the security level (for example,'explosives') can be automatically discharged to the opening screening area, processed out on the line, and then processed by security procedures.

In this way, the checked baggage handling system 300 establishes a non-stop line so that there is no congestion of baggage handling in each line due to security screening, and systematically establishes a linkage between the X-ray device and the line, so that the existing approximately 12 m/m/ By improving the baggage handling speed of about min to about 30~48 m/min, up to 1058 pieces of baggage per line per hour can be handled.

4 is a diagram illustrating a security search processing procedure in an opening search room in the checked baggage handling system according to an embodiment of the present invention.

4, the checked baggage handling system 400 includes a first conveyor line 401, a second conveyor line 402, a horizontal sorter 403, a rescan line 404, a tower light 405, and an unopened search. A terminal 406, a re-input line 407, an MES terminal 408, a photo sensor 409 to 416, 419, 420, an ATR 417, and an X-ray device 418 may be included.

The checked baggage handling system 400 captures the baggage inputted to the first conveyor line 401 with the X-ray device 418, and then recognizes the baggage identification information from the barcode attached to the baggage by the ATR 417, The captured image can be associated with identification information and stored in a database.

The X-ray device 418 is implemented by X-ray for OOG to take an X-ray image of baggage at a speed of 30m/min, and the checked baggage handling system 400 reads the captured image remotely. In order to display on the terminal in a pop-up format and classify the baggage according to the result of reading by the central reading terminal, the identification information of the baggage can be recognized using the ATR 417.

The checked baggage handling system 400 may transmit the photographed image and identification information to a remote central reading terminal, and classify the baggage according to the reading result by the central reading terminal.

For example, the checked baggage handling system 400 may move baggage classified as normal baggage from the first conveyor line 401 to the second conveyor line 402 and transfer it in a downstream direction with a predefined departure carousel. I can.

The checked baggage handling system 400 classifies the baggage that is read as containing an item that is suspected to be dangerous, as a suspect baggage, classifies the baggage that is read as containing the item that is suspected to be explosive, as ETD baggage, and selects the selected time ( Yes, baggage that is not read within '12 seconds') is classified as over-time baggage, and baggage that has not been imaged by the X-ray device 418 is classified as unexpressed baggage, and exceeds the specified specifications. Baggage to be classified as oversized baggage can be assigned an abnormal tag.

In this case, the checked baggage handling system 400 may change the direction of the horizontal sorter 403 and insert the baggage to which the abnormal tag has been assigned to the rescan line 404 instead of the second conveyor line 402.

In addition, the checked baggage handling system 400 can change the direction of the horizontal sorter 403 to insert the baggage into the re-scan line 404 even when an X-ray interface error, ATR tracking error, and baggage classification failure occur. have.

Specifically, when the shape of the baggage put in the X-ray apparatus 418 is out of the standard, the quantity of baggage put in the X-ray apparatus 418 and the quantity of baggage requested by the X-ray apparatus 418 are not the same. If a -ray interface error occurs, there may be a problem in baggage tracking, so the checked baggage handling system 400 may branch and process the baggage to the rescan line 404.

In addition, even if the shape of the baggage put into the ATR (417) is a variant, an ATR tracking error occurs in which the quantity of baggage that has passed through the ATR (417) and the number of baggage that has actually been recognized by the ATR (417) do not match. If this occurs, there may be a problem that the baggage image displayed on the central reading terminal and the actual baggage do not match, so the checked baggage handling system 400 may branch and process the baggage to the rescan line 404.

In addition, since baggage classification may be impaired when the attached baggage is separated from the sorting position or the baggage put in the X-ray device 418 is discharged together with the baggage that follows, the checked baggage handling system 400 can use the baggage rescan line ( 404).

The checked baggage handling system 400 uses a tower light 405 installed in the horizontal sorter 403 to change the handling procedure according to the classification for baggage to which an abnormal tag has been assigned, and a color associated with the reading result of the baggage. It can be turned on.

As an example, the checked baggage handling system 400 automatically discharges the baggage to the unopened search zone when the tower light is lit in red (classified as'suspect baggage'), displays the location of the dangerous object on the unopened search terminal 406, and You can have the passenger (airline) entrusted with you to remove the dangerous goods.

In addition, when the tower light is lit in yellow ('ETD baggage' classification), the checked baggage handling system 400 automatically discharges the baggage to the opening screen to search for explosives through the ETD device, and if there is an explosive, the security screening agent is asked. You can notify the identification information of the baggage.

In addition, the checked baggage handling system 400 may classify vertical baggage as'excessive baggage' and flash the tower light in multiple colors, and in this case, the baggage is automatically discharged to the opening screen and the baggage is placed. Can be processed to change.

The checked baggage handling system 400 transmits an image taken by an X-ray device provided in the re-scan line 404 to an opening retrieval terminal (recheck computer) 406 for the processed baggage, and the unopened retrieval terminal ( 406) can determine whether to remove the abnormal tag from the baggage.

At this time, the checked baggage handling system 400 does not dispose of the baggage to the rescan line 404 when the tower light is lit in green ('time limit baggage') or blue (read image not displayed). The image of the baggage photographed by the provided X-ray device may be transmitted to the opening search terminal 406 to request reading.

The checked baggage handling system 400 may move the baggage from which the abnormal tag is removed according to a result of reading from the unpacking search terminal 406 from the rescan line 404 to the reload line 407.

The checked baggage handling system 400 may utilize a manual barcode input terminal, a Manual Encoding Station (MES) terminal 408 for re-insertion operation. The MES terminal 408 may be implemented as, for example, a touch screen or a barcode scanner.

That is, the checked baggage handling system 400 may recognize the barcode of the baggage placed on the re-entry line 407 through the MES terminal 408 and display the read result of the baggage on the MES terminal 408.

When the confirmation of normal baggage is input from the MES terminal 408, the checked baggage handling system 400 may put the baggage placed on the reloading line 407 into the second conveyor line 402.

The checked baggage handling system 400 includes a plurality of photo sensors 409 to 416 and 419 installed in each of the first conveyor line 401, the second conveyor line 402, the rescan line 404, and the reload line 407. 420) can be used to detect and handle baggage.

5 is a view for explaining a data flow between an X-ray device and an ATR and a reading PC in the checked baggage handling system according to an embodiment of the present invention.

5 shows an embodiment of implementing the checked baggage handling system of the present invention as a PLC system (BHS) to handle baggage.

Referring to the data flow diagram 510 and the table 520 of FIG. 5, in step 501, the PLC system may transmit a virtual identification of baggage (“VID”) to the X-ray apparatus.

In step 502, the X-ray device photographs the baggage, and transmits the photographed image (X-ray image) together with the VID to the X-ray server. In step 503, the X-ray server transmits the photographed image and the VID. Can be transferred to a remote reading PC.

In step 504, the reading PC may read whether there is an item that is estimated to be dangerous or explosive in the baggage or within a predetermined standard through the captured image, and transmit the read result to the X-ray server together with the captured image and VID. .

In step 505, the X-ray server transmits the Baggage Evaluation Result ('BER') and VID to the X-ray device, and in step 506, the X-ray device transmits the BER and VID. Can be transferred to the PLC system.

In step 507, the ATR transmits the actual ID (Baggage Identification,'BID') of the read baggage from the barcode attached to the baggage to the PLC system, and in step 508, the PLC system transmits the VID and BID to the X-ray server. Can be transferred to.

Hereinafter, in FIG. 6, the work flow of the checked baggage handling system 200 according to embodiments of the present invention will be described in detail.

6 is a flow chart showing a procedure of a method for handling checked baggage according to an embodiment of the present invention.

The method of handling checked baggage according to the present embodiment may be performed by the above-described checked baggage handling system 200.

Referring to FIG. 6, in step 610, the checked baggage handling system 200 detects whether baggage is put into the conveyor line.

In step 620, the checked baggage handling system 200 reads a first image of the baggage upon detection of the baggage input.

The checked baggage handling system 200 may obtain an image (first image) of the baggage from the X-ray apparatus, and classify the baggage according to a reading result input from the central reading terminal for the first image.

For example, the checked baggage handling system 200 classifies baggage that is read as containing items that are suspected of being dangerous, as'suspect baggage', and classifies baggage that is read as containing items that are suspected as explosives as'ETD baggage'. And, baggage that has not been read within a selected time period (e.g., '12 seconds') is classified as'time-out baggage', and baggage that has not been imaged by the X-ray device 418 is'unreadable image not displayed. Baggage can be classified as'baggage', and baggage that exceeds the specified standard is classified as'excessive baggage', and then an abnormal tag may be assigned according to the above classification.

That is, the checked baggage handling system 200 uses the identification information recognized from the barcode of the baggage to which the abnormal tag has been assigned, and the'suspect baggage','ETD baggage','timeout baggage', It can be recorded in the database with at least one classification of'expressed baggage' and'excessive baggage'.

In step 630, the checked baggage handling system 200 determines whether the baggage classified according to the reading result of the first image is normal baggage.

The checked baggage handling system 200 may check whether identification information is recorded in the database, and if not, may determine that the baggage is normal.

If it is determined as normal baggage, in step 680, the checked baggage handling system 200 transfers the normal baggage to the departure carousel of the designated line by the conveyor line.

If, as a result of the reading in step 630, the baggage is not determined as normal baggage, in step 640, the checked baggage handling system 200 branches the baggage to the rescan line, and in step 650, the checked baggage handling system 200 reads the second image of the baggage put into the rescan line.

If identification information is recorded in the database, the checked baggage handling system 200 may determine the baggage as abnormal baggage, and change the direction of the horizontal sorter to insert the baggage into the re-search line.

At this time, according to the classification recorded in the database along with the identification information, the checked baggage handling system 200 may turn on the tower light installed in the horizontal sorter, so that the baggage is handled differently according to the lighting color of the tower light.

For example, the checked baggage handling system 200 illuminates the tower light in red indicating suspicious baggage, yellow indicating ETD baggage, green indicating exceeding the time limit, blue indicating no read image, or flashing multiple colors to determine the specified standard. May indicate excess.

Checked baggage handling system 200 automatically discharges the inserted baggage when the tower light is lit in red (suspicious baggage), yellow (ETD baggage), and flashing (exceeding the standard), and is assumed to be dangerous or explosive. The image of the baggage (second image) may be obtained from the X-ray apparatus after processing to remove the baggage from the baggage or to change the shape in which the baggage is placed.

In addition, when the tower light is lit in green (exceeding the time limit) or blue (no read image displayed), the checked baggage handling system 200 does not dispose of the baggage to an 2 images) can be acquired.

In step 660, the checked baggage handling system 200 determines whether the baggage is normal baggage according to a result of reading the second image.

That is, the checked baggage handling system 200 displays the second image on the unopened search terminal (recheck terminal) provided on the re-search line, and determines whether to remove the abnormal tag from the baggage according to the reading result input by the unopened search terminal. I can.

If it is a normal baggage, the checked baggage handling system 200 may remove an abnormal tag and delete identification information of the baggage from the database.

In step 660, as a result of reading the second image, if it is not determined as a normal baggage (if the abnormal tag is not removed), the process moves to step 640 to process the baggage again on the rescan line.

If, as a result of reading the second image in step 660, the baggage is determined to be normal baggage (when the abnormal tag is removed), in step 670, the checked baggage handling system 200 performs a reloading line. Into the conveyor line again.

The checked baggage handling system 200 moves the baggage from which the abnormal tag has been removed from the rescan line to the reload line, and then displays the read result of the second image on the MES terminal provided in the reload line 309, When finally confirmed as normal baggage through the MES terminal, the baggage on the reloading line may be reloaded into the conveyor line.

In step 680, the checked baggage handling system 200 transfers the normal baggage to the departure carousel by the conveyor line.

As described above, according to an embodiment of the present invention, by constructing a non-stop line so that congestion due to security search does not occur in each line, it is possible to improve baggage handling speed and increase baggage throughput.
