Description

  The present invention relates to a load arrangement order recognition support system for grasping the arrangement order of packages arranged in an unordered manner without being distinguished for each destination, such as a load unloaded from a cargo plane.

  For example, in the case of air cargo transported by a cargo plane, it is performed via a relay airport. At the transit point, all cargo is unloaded from the cargo plane, and each cargo is transferred to another cargo plane for each destination.

  The cargo dropped from the cargo plane is arranged in a line on the side of the cargo plane in order to distinguish and distribute each destination. At this time, since the work of unloading is prioritized, the cargo unloaded from the cargo plane is arranged in an irregular order without being distinguished for each destination. In other words, the cargoes that are unloaded from the cargo plane are towed in order with the pallet on which the cargo is loaded being sequentially pulled by the towing vehicle, in the order of being unloaded.

  Then, as the person in charge moves along the freight line arranged in a row, the pallet number on which the freight is loaded is compared with the materials at hand to ascertain the destination of the freight on that pallet and The driver is instructed and towed. At this time, depending on the scale of the cargo plane, the length of the cargo row is about 100 m, and the person in charge walks along the cargo row and performs confirmation work while stopping at the position of each pallet. In addition, since the destinations of the cargo are out of order, in some cases, the person in charge must work while going back and forth, resulting in poor work efficiency and time.

  On the other hand, a portable terminal for cargo tracking and a cargo tracking system have been proposed (see Patent Document 1). This cargo tracking system uses a mobile terminal with a camera function, barcode analysis function, and communication function to obtain the ID of each cargo displayed in the barcode on the delivery slip, and associates the ID with the latest ID. The status is transmitted to the server using the communication function of the mobile phone.

JP 2006-108865 A

  In the freight tracking system disclosed in Patent Document 1, in order to improve the accuracy of a freight tracking service performed by a transportation company or the like, the status of the freight is grasped, and the order of the loads is not recognized.

  For example, it is conceivable to attach an electronic tag to the pallet so as to efficiently confirm the cargo in the cargo train. However, since the number of pallets distributed is enormous, and is owned by a plurality of suppliers, it is almost impossible to attach a common electronic tag to all pallets.

  Therefore, the present invention can quickly and accurately confirm the order of loads in the cargo row without the person in charge walking along the cargo row, and the person in charge can reliably confirm the driver of the towing vehicle. The purpose is to provide a load sequence recognition support system that allows instructions to be pulled.

  As a technical means for achieving the above-mentioned object, the load arrangement order recognition support system according to the present invention is arranged on the pallet by loading the pallets on which the load is placed on the carriage and arranging them in a random order. Based on the pallet number, in the load arrangement order recognition support system for confirming the destination of the load placed on the pallet and grasping the order of the load in order to tow by the towing vehicle for each destination, A vehicle-mounted terminal device equipped with a GPS function and a photographing means are attached to a tow vehicle, and a person in charge of grasping the order of loads is carried by the person in charge, and communication is performed between the vehicle-mounted terminal device and the mobile terminal device. Each of the carts includes a recognition server that exchanges information via a line and a separation sensor that detects that the connection state between the towing vehicle and the cart is released, and the cart is towed by the towing vehicle. Almost Arranged on a straight line to separate the tow vehicle from the carriage, and when the in-vehicle terminal device receives the separation signal detected by the separation sensor, the photographing means photographs the pallet number to create a still image In addition, the position of the tow vehicle is captured from the position information by the GPS function, and the still image and the position information of the tow vehicle captured by the GPS function are transmitted from the in-vehicle terminal device to the recognition server, and the recognition The server sequentially compares the still images and the position information transmitted from the in-vehicle terminal device to calculate the arrangement order, and the recognition server transmits the calculated arrangement order data to the portable terminal device, The mobile terminal device displays the still images on the display unit of the mobile terminal device based on the received order data so that the person in charge can grasp the order of the palettes It is characterized in that.

  For example, cargo loaded on a cargo plane is placed on a pallet, and a pallet number is attached to the pallet by printing or the like so that the destination of the cargo can be specified. When the cargo arrives at the transit point, it is necessary to classify the cargo according to each destination and reload the cargo into the corresponding cargo plane or transport vehicle. At this time, the unloaded cargo is mounted on the carriage together with the pallet, pulled by the towing vehicle, and arranged in a row on the side of the cargo plane. At this time, they are arranged so as to be arranged substantially in a straight line. When the carriage is separated from the towing vehicle, the separation sensor detects the separation and sends a separation signal to the in-vehicle terminal device mounted on the towing vehicle. Upon receipt of this separation signal, the pallet number is photographed by the photographing means of the in-vehicle terminal device, and the still image is created. Since the position to which the pallet number is assigned is substantially constant, the photographing means can be fixedly provided at a fixed position of the towing vehicle. If the separated signal is received, the position of the tow vehicle captured by the GPS (Global Positioning System) function at that time is acquired, and the position information and the still image are sent to the recognition server. Next, the cart on which the next cargo unloaded from the cargo plane is placed is arranged next to the previously arranged cargo on the straight line, and the towing vehicle is separated from the cart.

  Since the recognition server has acquired the still images of the pallet numbers arranged on the straight line and the position information of the tow truck when it is separated from the cart loaded with the pallet, the position information data Are compared and the still images are arranged in the order based on the position information.

  The recognition server sends out still images in the calculated arrangement order to the portable terminal device, and the portable terminal device displays the still images with the palette numbers in the arrangement order. The person in charge grasps the destination of the cargo placed on each pallet by visually recognizing the still image, and instructs the driver of the towing vehicle to pull each cargo for each destination.

  In addition, the load arrangement order recognition support system according to the invention of claim 2 is provided with a reference terminal device in the vicinity of the cargo line, and the recognition server includes the positional information sent from the towing vehicle, and the reference terminal. According to the position information of the apparatus, the position of the tow vehicle is obtained using the position of the reference terminal apparatus as a reference point, and the arrangement order is calculated.

  The position information acquired by the GPS function includes an error, and the error constantly fluctuates. On the other hand, since the timing at which the carriage is separated is basically different for each carriage, the error included in the position information of each carriage is also different. In the support system according to the present invention, since it is only necessary to grasp the arrangement of the carriages, that is, it is only necessary to know the relative position between the carriages, when the distance between the carriages is long, it varies depending on the performance of the GPS function. In the case of 5 to 10 m or more, there is no problem in calculating the relative position even if the position information error varies. However, in the case assumed by this support system, the distance between the carriages can be considered to be within 1 m. Therefore, the arrangement order may be erroneously calculated due to the difference in the error. Therefore, the position information sent from the towing vehicle is converted into a value based on the distance from the reference terminal device, and the pallet arrangement order is calculated, and this time-varying error is offset. is there.

  In addition, the load arrangement order recognition support system according to the invention of claim 3 uses a commercial line provided by a telecommunications carrier for a communication line between the in-vehicle terminal device, the portable terminal device, and the recognition server. It is characterized by.

  A communication line using a wireless local area network (LAN) can be used. However, in the case of a baggage transported by a cargo plane, the airport is vast, and the recognition server is a building that is easy to manage, such as a control tower or a roof. Therefore, the wireless LAN may have a huge amount of equipment such as antennas. In addition, since there may be many wireless systems in the airport, there is a risk of interference with them. In view of these circumstances, a commercial line that is advantageous for transmitting image data is used. As this commercial line, for example, there is a so-called W-CDMA (Wideband Code Division Multiple Access) that adopts a wireless access system of a third generation mobile phone such as FOMA (registered trademark).

  According to the load arrangement order recognition support system according to the present invention, the person in charge can grasp the load arrangement order without walking along the freight line. For this reason, the operation | work which grasps | ascertains an arrangement order can be simplified, and the time of the distribution operation | work of the destination of a load can be shortened. Therefore, for example, in the case of air freight, the occupation time of the work area by the cargo sorting operation in the airport can be shortened, and the use efficiency of the airport can be improved.

  In addition, according to the load arrangement order recognition support system according to the invention of claim 2, even if there is a temporal change in the error of the GPS function, the change is offset and the accurate arrangement order can be grasped. . For this reason, it can prevent as much as possible that a load is accidentally sorted.

  Further, according to the load arrangement order recognition support system according to the invention of claim 3, since the equipment cost is reduced, this system can be easily introduced.

  Hereinafter, based on the illustrated preferred embodiment, a load arrangement order recognition support system according to the present invention will be specifically described. In this embodiment, the arrangement order is recognized when the cargo 1 transported to the airport at the waypoint by the cargo plane 10 is sorted by destination.

  The load arrangement order recognition support system according to the present invention includes a towing vehicle 4 for towing a carriage 3 for loading cargo 1 together with a pallet 2 on which the cargo 1 is placed, and an in-vehicle terminal device mounted on the towing vehicle 4. 5, the camera 6 mounted on the tow truck 4 and connected to the in-vehicle terminal device 5 as a photographing means, and the arrangement order of the cargo 1 are ascertained. Mobile terminal 7 possessed by the person in charge P who instructs whether or not tow the vehicle, a control tower, a recognition server 9 installed in a shed 8 where the cargo 1 is temporarily placed for tariffs, and the like. The in-vehicle terminal device 5 and the mobile terminal device 7 are connected to exchange information via a commercial communication line provided by a communication carrier. As this communication line, a LAN or the like can be used. However, in a large site such as an airport, a commercial line should be used from the viewpoint of equipment cost or interference prevention of the radio system in the airport. Is advantageous. For example, a third-generation mobile phone wireless access method such as FOMA (registered trademark) can be used.

  The in-vehicle terminal device 5 has a GPS function so that the position information of the towing vehicle 4 can be captured. Further, a separation sensor (not shown) for detecting the state where the carriage 3 is separated by releasing the connection with the carriage 3 to which the towing vehicle 4 has been towed is provided. A separation signal generated from the separation sensor when the carriage 3 is separated from the towing vehicle 4 is received by the in-vehicle terminal device 5.

  A process when the arrangement order is recognized by the person in charge by the load arrangement order recognition support system configured as described above will be described.

  The cargo 1 is loaded on the cargo plane 10 while being placed on the pallet 2. As shown in FIG. 3, the pallet 2 is provided with a tag 2a on which a pallet number for identifying the pallet 2 is printed, etc., and the destination of the cargo 1 is recognized corresponding to the pallet number. it can. When the cargo plane 1 arrives at the waypoint, the loaded cargo 1 is unloaded. At this time, the pallet 2 is unloaded, loaded on the waiting cart 3, pulled by the towing vehicle 4, and lined up in a line on the side of the cargo plane 10 as shown in FIG. become.

  When the trolley 3 is pulled by the traction vehicle 4 and positioned on the straight line, the trolley 3 is separated from the traction vehicle 4. At this time, the separation sensor detects that the carriage 3 and the towing vehicle 4 are separated and generates a separation signal. When this separation signal is received by the in-vehicle terminal device 5, the camera 6 captures the pallet number of the tag 2a attached to the pallet 2 and creates a still image thereof. Further, the position information captured by the GPS function with respect to the towing vehicle 4 at the time of separation is acquired by the in-vehicle terminal device 5.

  The in-vehicle terminal device 5 sends the position information and the still image with the pallet number to the recognition server 9. The recognition server 9 stores the received still image and position information as a pair of the ordered still data. On the other hand, each time the carriage 3 is sequentially pulled by the tow truck 4 and arranged on the straight line, the position information and the still image are sent to the recognition server 9. The recognition server 9 calculates the relative arrangement order by comparing the stored arrangement order data with the respective position information. The calculated relative arrangement order data is sent to the portable terminal device 7 possessed by the person in charge P.

  The mobile terminal device 7 displays the received arrangement order data as an image on the display unit 7a of the mobile terminal device 7 as information, as shown in FIG. 2A. This display image is an image of the pallet number of the tag 2a displayed in the order in which the pallets 2 are arranged. For example, when the interval between adjacent pallets 2 is large, It is preferable to display images with a wide interval. In addition, the recognition server 9 may process the sent still image into text data and display it as text data on the display unit 7a. FIG. 2B shows an example in which destination information of each pallet is displayed on the screen. The person in charge P is considered to know the destination information of each pallet by referring to the material written on the form. If the destination information can be acquired by the recognition server of the support system as digital data, the information is recognized as digital data. In the case where the server cannot obtain it, it is conceivable to display it on the portable terminal device 7 as image data obtained by scanning the entry contents of the paper. In this way, the person in charge P grasps the arrangement order of the pallets on the screen of FIG. 2A of the mobile terminal device 7 without printing and carrying paper materials, and each pallet is displayed on the screen of FIG. 2B. It becomes possible to confirm the destination of. As described above, when the still image is converted into text data and the destination information is acquired as digital data, both can be linked to display the order of the palettes and the destination information on one screen.

  The person in charge P can grasp the destination corresponding to the arrangement order of the cargo 1 by visually checking the arrangement order data displayed on the display unit 7 a of the mobile terminal device 7. Therefore, based on this arrangement order data, the driver of the towing vehicle 4 is instructed to tow the destination of the cargo 1 together.

  By the way, although the cargo 1 unloaded from the cargo plane 10 is arranged on the straight line, there is a possibility that an error may occur in the order of the cargo 1 due to the temporal variation of the positional information error acquired from the GPS function. . Therefore, a reference terminal device 11 similar to the in-vehicle terminal device 5 is installed. For example, as shown in FIG. 1, the reference terminal device 11 is installed at a position facing the area where the cargo handling work of the cargo 1 is performed in the shed 8. The reference terminal device 11 may be portable and installed near the work area during cargo handling work. The reference terminal device 11 is provided with a GPS function in the same manner as the in-vehicle terminal device 5, and the position information is transmitted to the recognition server 9.

  In the load arrangement order recognition support system including the reference terminal device 11, the recognition server 9 uses the position information of the tow vehicle 4 sent from the in-vehicle terminal device 5 and the position information of the reference terminal device 11 tow the vehicle. The position of the car 4 is converted into a distance from the reference terminal device 11 and the arrangement order is calculated. Since the reference terminal device 11 is the same as the in-vehicle terminal device 5, fluctuations that occur in the positional information of the towing vehicle 4 acquired by these are offset when the recognition server 9 calculates the arrangement order. Therefore, accurate arrangement order data can be acquired.

  According to the load sequence recognition support system according to the present invention, the load is pulled by a tow vehicle, and the load is placed by separating the tow vehicle from the cart loaded with the load. Since the pallet number can be recognized and notified to the person in charge, the person in charge can grasp the arrangement order without walking along the load, which contributes to speeding up the work of allocating the destination of the load.

It is a figure explaining the structure of the arrangement | sequence recognition recognition support system of the load which concerns on this invention. It is a figure explaining the display content of the portable terminal device which the person in charge of the load distribution operation | work in the arrangement order recognition assistance system concerning this invention has. It is a figure explaining the state in the case of pulling cargo with a tow vehicle.
