Patent No. 4260447 JP, 2003-313856, A JP, 2002-37453, A

In the method described in Patent Document 1, since the gate clerk needs to select an inspection target from a plurality of containers or vehicles, the inspection by the gate clerk may take time due to the selection operation. For example, when a plurality of entrance gates are crowded, it is expected that a large number of containers or vehicles will be displayed on the checker terminal, and it will take time for the gate clerk to select one inspection object from among them. Therefore, it is desired to shorten the inspection time of the moving body or cargo that is about to enter.

A gate management system according to one aspect of the present invention, an acquisition unit that acquires a mobile body identifier that uniquely identifies one mobile body that has come to an entrance gate, and a cargo identifier that uniquely identifies a cargo of the mobile body, A generation unit for generating screen data for displaying an inspection screen including a moving body identifier and a cargo identifier, wherein the inspection screen allows a gate clerk of an entrance gate to select one moving body from a plurality of moving bodies. It does not include the interface of the above, but includes an interface for inputting the inspection result of the cargo of one mobile body to the gate clerk. The generation unit and screen data for displaying the inspection screen on the checker terminal of the gate clerk. And a transmitting unit for transmitting to the checker terminal.

A gate management method according to one aspect of the present invention is a gate management method executed by a gate management system including at least one processor, wherein a mobile body identifier that uniquely identifies one mobile body that has arrived at an entrance gate is provided. An acquisition step of acquiring a cargo identifier that uniquely identifies a cargo of the mobile body, and a generation step of generating screen data for displaying an inspection screen including the mobile body identifier and the cargo identifier, wherein the inspection screen is , Not including an interface for allowing a gate clerk of an entrance gate to select one moving body from a plurality of moving bodies, but including an interface for causing the gate clerk to input a cargo inspection result of one moving body, The method includes a generation step and a transmission step of transmitting screen data to the checker terminal of the gate attendant so as to display the inspection screen on the checker terminal.

A gate management program according to an aspect of the present invention, an acquisition step of acquiring a mobile body identifier that uniquely identifies one mobile body that has come to an entrance gate, and a cargo identifier that uniquely identifies a cargo of the mobile body, A generation step for generating screen data for displaying an inspection screen including a moving body identifier and a cargo identifier, wherein the inspection screen causes a gate clerk of the entrance gate to select one moving body from a plurality of moving bodies. It does not include the interface of, but includes an interface for inputting the inspection result of the cargo of one moving body to the gate clerk. The generation step and screen data for displaying the inspection screen on the checker terminal of the gate clerk. And a transmitting step of transmitting to the checker terminal.

In such an aspect, the checker terminal displays one moving object coming to the entrance gate as an inspection target from the beginning. Therefore, the gate clerk can immediately start the inspection of one mobile body (the mobile body displayed on the checker terminal) without selecting one from the plurality of mobile bodies. Inspecting the vehicle or cargo at the entrance gate is shortened because the gate clerk does not have to select the vehicle.

In the gate management system according to another aspect, the acquisition unit acquires the mobile body identifier input or confirmed by the surveillance staff who has confirmed the image of the mobile body taken by the camera at the entrance gate, and subsequently, Alternatively, the cargo identifier corresponding to the mobile unit identifier may be acquired. It is possible to provide accurate information about the moving body and the cargo to the gate staff by executing the acquisition of the cargo identifier and the subsequent processing triggered by the input or confirmation of the moving body identifier by the operation of the observer. it can. Since the gate clerk does not select the moving body on the inspection screen, it is important to accurately provide the gate clerk (checker terminal) with information on one moving body to be inspected.

In the gate management system according to another aspect, the transmission unit may transmit the screen data to the monitoring terminal so that the inspection screen is displayed on the monitoring terminal and the monitoring staff inputs the inspection result. Since the time and labor required for the gate staff to input the inspection result are reduced by the amount of the inspection person inputting the inspection result, it is expected that the inspection time of the moving body or cargo can be shortened.

In the gate management system according to another aspect, the inspection screen includes a plurality of inspection items for the cargo of one moving body, and the transmitting unit first transmits the screen data to the monitoring terminal, and a part of the plurality of inspection items is included. The screen data indicating that the inspection result is input may be received from the monitoring terminal, and the received screen data may be transmitted to the checker terminal. Since the time and labor required for the gate staff to input the inspection result are reduced by the amount of the inspection person inputting the inspection result, it is expected that the inspection time of the moving body or cargo can be shortened. In addition, since the inspection screen is sent to the checker terminal after the input of the supervisor is completed, it is possible to prevent both the supervisor and the gate clerk from redundantly inspecting one inspection item. This can also contribute to shortening the inspection time.

In the gate management system according to another aspect, the entrance gate includes two or more lanes each provided with a camera, and the monitoring terminal displays an image of one lane with priority over an image of another lane. A display unit is provided, and the image display unit analyzes the image of each camera to identify the lane with the longest row of moving bodies and preferentially display the image of the identified lane, or to the monitoring terminal. The image of the lane corresponding to the checker terminal that transmitted the request signal may be preferentially displayed. By preferentially displaying the image of a specific lane in this way, the occupant processes the lane, so that the time for the mobile unit to wait for the inspection can be shortened as a whole of the gate management system. Alternatively, it is possible to reduce the variation in the time required for the inspection of each lane.

According to one aspect of the present invention, it is possible to shorten the inspection time of a moving body or a cargo that is about to enter.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements will be denoted by the same reference symbols, without redundant description.

The functions and configuration of the gate management system 1 according to the embodiment will be described with reference to FIGS. 1 to 7. The gate management system 1 is a computer system that manages entrance of a moving body that loads cargo. A "moving body" is a device that transports a person or thing from one place to another. The type of mobile body is not limited in any way. For example, the vehicle may be a motorcycle, bicycle, train, water vehicle, underwater vehicle, or airplane. Therefore, the route along which the moving body travels may be a land route, a water route, or an air route. A "cargo" is an item that is transported by a mobile body. “Entry” means that the moving body enters a predetermined area such as a specific facility or area. In the present embodiment, a truck is shown as an example of the moving body, a container is shown as an example of the cargo, and a container terminal that stores the container is shown as an example of an area where the moving body enters.

The gate management system 1 distinguishes individual cargoes by a combination of a mobile body identifier that uniquely identifies a mobile body and a cargo identifier that uniquely identifies a cargo. The vehicle number shown on the license plate of the truck is shown as an example of the mobile body identifier, and the combination of the container number and the seal number is shown as an example of the cargo identifier. The container number is a number that identifies the container and is generally printed on the side surface of the container. The sticker number is the number printed on the sticker that seals the door of the container containing the package.

Container terminals typically include yards, gates, and incidental equipment. The yard is a space for temporarily storing the container. The gate is the entrance and exit of the yard, and the entrance and exit of containers is managed at this gate. Ancillary equipment is other equipment necessary for the container terminal, such as a central control room, customs office, and quarantine station.

Generally, the gate is divided into an entrance gate and an exit gate. Since the gate management system 1 manages the container that enters the yard from the entrance gate, the mechanism will be described in detail in this embodiment. FIG. 1 schematically shows an example of an entrance gate to which the gate management system 1 is applied. The entrance gate comprises at least one lane 2. Lane 2 is a road through which a truck carrying a container passes. FIG. 1 shows two lanes 2. Each lane 2 is provided with a check-in booth 3 equipped with a circuit breaker, a camera 4 for photographing a truck or a container, and an antenna 5 for acquiring data from a vehicle-mounted device of the truck. There is DSRC (Dedicated Short Range Communications) as a wireless communication technology for receiving data from the vehicle-mounted device, but the wireless communication method is not limited to this. A gate attendant 6 who visually inspects the container is arranged in each lane 2. Two or more gate attendants 6 may be arranged in one lane 2, or one gate attendant 6 may be in charge of a plurality of lanes 2. An observer 8 in the central control room 7 can confirm the image of the camera 4 in each lane 2.

The gate management system 1 includes a server 10, a monitoring terminal 20, a checker terminal 30, and a database group 40 in order to manage entrance of a truck carrying a container. The server 10 is a computer that executes main processes of the gate management system 1. The monitor terminal 20 is a computer operated by the monitor 8. The checker terminal 30 is a computer operated by the gate attendant 6. The number of monitoring terminals 20 and checker terminals 30 is not limited. Also, the types of computers that function as the monitoring terminal 20 and the checker terminal 30 are not limited. For example, the monitoring terminal 20 placed in the central control room 7 may be a stationary personal computer. The checker terminal 30 possessed by the gate clerk 6 working at the entrance gate (outdoor) may be a mobile terminal such as a tablet terminal or a high-performance mobile phone (smartphone). The database group 40 is a set of one or more databases that store data necessary for processing in the gate management system 1. The place where the server 10 and the database group 40 are installed is not limited, and these devices may be provided inside or outside the container terminal.

An example of processing for managing entrance of trucks and containers using the gate management system 1 is generally performed as follows. When a truck comes to the entrance gate (more specifically, one lane 2) and stops at a certain position (for example, in front of a circuit breaker), the camera 4 photographs the license plate of the truck. Generate an image. The gate management system 1 analyzes the image and acquires the vehicle number that uniquely identifies the truck. In one aspect, the gate management system 1 acquires the vehicle number when the surveillance staff member 8 confirms the camera image. Further, the gate management system 1 acquires the container number and the seal number of the container loaded on the truck from the antenna 5. Specifically, the vehicle-mounted device of the truck stores the container number and the seal number in advance, and when communication is established between the vehicle-mounted device and the antenna 5, the gate management system 1 acquires these numbers. ..

When the vehicle number, the container number, and the seal number are acquired, the gate management system 1 generates screen data showing an inspection screen for inputting the result of the visual inspection of the truck. Then, the gate management system 1 transmits the screen data to the checker terminal 30 of the gate clerk 6. The checker terminal 30 displays the inspection screen. The inspection screen displays the vehicle number of one truck and the container number and seal number of the container loaded by the truck. In addition, the inspection screen displays an interface that accepts input of inspection results for the container of that truck.

The gate clerk 6 compares the inspection screen with the truck and container in front of the eyes, and inspects whether the vehicle number, the container number, and the seal number shown on the inspection screen match the actual ones. Further, the gate clerk 6 inspects the appearance of the container and inputs the result on the inspection screen. It is also possible that a plurality of gate staff members 6 are arranged in one lane 2 and they share one container for inspection. The inspection result is registered in a predetermined database. If there is no problem in the inspection result, the gate clerk 6 performs a process or procedure for putting the truck in the yard. In this case, the truck goes to a designated point in the yard where the container is unloaded. On the other hand, if there is a problem in the inspection result, the gate clerk 6 performs a predetermined process or procedure without guiding the truck into the yard. For example, if the seal is broken or the container has dents or holes, the gate clerk 6 will not admit the truck.

FIG. 2 schematically shows the overall configuration of the gate management system 1. Each device in the system can perform data communication with another device via a communication network N such as a LAN.

FIG. 3 shows a general hardware configuration of the computer 100 that functions as the server 10, the monitoring terminal 20, or the checker terminal 30. The computer 100 includes a processor 101 that executes an operating system and application programs, a main storage unit 102 that includes a ROM and a RAM, an auxiliary storage unit 103 that includes a hard disk and a flash memory, a network card or a wireless network. The communication controller 104 includes a communication module, an input device 105 such as a keyboard, a mouse, and a touch panel, and an output device 106 such as a monitor and a touch panel. Specific hardware elements may vary from computer to computer. For example, stationary computers typically include a keyboard and mouse as input devices 105 and a monitor as output device 106. A tablet terminal or a high-performance mobile phone (smartphone) generally includes a touch panel as the input device 105 and the output device 106.

FIG. 4 shows a functional configuration of the gate management system 1. The functional elements of each device are realized by loading predetermined software onto the processor 101 or the main storage unit 102 and executing the software. The processor 101 operates the communication control unit 104, the input device 105, or the output device 106 according to the software to read and write data in the main storage unit 102 or the auxiliary storage unit 103. The data or database required for processing is stored in the main storage unit 102 or the auxiliary storage unit 103.

FIG. 4 also shows details of the database group 40. In this embodiment, the database group 40 includes a lane database 41 and a container database 42. The “database” is a functional element (storage unit) that stores a data set so as to be able to handle arbitrary data operations (for example, extraction, addition, deletion, overwrite, etc.) from a processor or an external computer. The database mounting method is not limited, and may be a database management system or a text file, for example.

The lane database 41 is a device that stores lane information indicating devices installed or arranged in the lane. FIG. 5 shows an example of lane information. In this embodiment, each record of the lane information includes a lane number that uniquely identifies the lane and an identifier (ID) of each device installed or arranged in the lane. In the present embodiment, a camera ID, an antenna ID, and a terminal ID (identifier of the checker terminal 30) are shown as the device identifier. The correspondence between the lane number, the camera ID, and the antenna ID is determined when the camera and the antenna are installed. The correspondence between the lane number and the terminal ID is determined when the gate clerk 6 is placed in the lane, so that the terminal ID can be updated every time the gate clerk 6 is replaced. In the example of FIG. 5, a plurality of terminal IDs are associated with the lane “2”, which means that a plurality of gate attendants 6 inspect the container in the lane “2”.

The container database 42 is a device that stores container information indicating details of the container. The container information is also information indicating the correspondence relationship between the truck, the container, and the seal, and also information indicating the inspection result of the appearance of the container. FIG. 6 shows an example of a record of container information. In this embodiment, each record of container information includes a vehicle number, a container number, a seal number, and an inspection result. In the present embodiment, the initial value of the item of the inspection result is a null value (NULL), and either “OK (no problem found)” or “NG (no problem found)” is registered by the inspection. To be done. In FIG. 6, null values in the inspection item column are indicated by hyphens. FIG. 6 shows, for example, that a truck “XX123456” is loaded with a container “YY234567” with a seal “ZZ654321” and that there was no problem with that container. FIG. 6 also shows that the truck “XX345678” is loaded with a container “YY987654” with a seal “ZZ654789” and that the container has not yet been inspected.

The configuration of each database and each record in the database group 40 is not limited to the above, and any normalization or redundancy may be performed on each database.

Returning to FIG. 4, the server 10 includes a number acquisition unit 11 (acquisition unit), a screen generation unit 12 (generation unit), a screen transmission unit 13 (transmission unit), and a registration unit 14 as functional components.

The number acquisition unit 11 is a functional element that acquires a moving body identifier of one moving body to be inspected and a cargo identifier of a cargo of the moving body. More specifically, the number acquisition unit 11 acquires a vehicle number, a container number, and a seal number corresponding to one truck.

The vehicle number acquisition method is not limited. For example, the number acquisition unit 11 may acquire the vehicle number based on the image of the truck obtained by the camera 4 provided at the entrance gate. Specifically, the image captured by the camera 4 is sent to the monitoring terminal 20 together with the camera ID, and the monitoring terminal 20 displays the image. The observer 8 checks the vehicle number by looking at the license plate of the truck shown in the image, and inputs the vehicle number at the monitoring terminal 20. Alternatively, the monitoring terminal 20 or another computer analyzes the image and acquires the vehicle number as text data, and the monitoring terminal 20 displays the textified vehicle number. The monitor 8 compares the vehicle number with the image, corrects the vehicle number in text if necessary, and determines the vehicle number to be transmitted to the gate attendant 6 on the monitoring terminal 20. The monitoring terminal 20 transmits the vehicle number input or confirmed to the server 10, and the number acquisition unit 11 receives this vehicle number. Alternatively, the number acquisition unit 11 receives the image of the moving body together with the camera ID from the camera 4 without passing through the monitoring terminal 20 (that is, without passing through the operation of the surveillance staff 8), and analyzes the image. The vehicle number may be acquired at.

Alternatively, the number acquisition unit 11 may acquire the vehicle number received by the entrance gate antenna 5 from the vehicle-mounted device of the truck. Specifically, the number acquisition unit 11 receives the vehicle number and the antenna ID from the antenna 5.

The method for obtaining the container number and the seal number is also not limited. For example, the number acquisition unit 11 may access the container database 42 and read the container number and the seal number corresponding to the acquired vehicle number. Alternatively, the number acquisition unit 11 may acquire the container number and the seal number that the antenna 5 has received from the vehicle-mounted device of the truck together with the antenna ID. Regardless of whether it refers to the container database 42 or receives from the antenna 5, the number acquisition unit 11 first acquires the vehicle number input or confirmed by the monitor 8 using the monitoring terminal 20, and then the vehicle. You may acquire the container number and seal number corresponding to a number.

As described above, the method of obtaining the vehicle number, the container number, and the seal number is not limited. In any case, the number acquisition unit 11 outputs these numbers to the screen generation unit 12.

The number acquisition unit 11 also specifies in which lane 2 the track to be processed is located. The number acquisition unit 11 refers to the lane database 41 to identify the lane number corresponding to the received camera ID or antenna ID. Then, the number acquisition unit 11 outputs the lane number to the screen generation unit 12 together with the vehicle number, the container number, and the seal number.

The screen generation unit 12 is a functional element that generates screen data for displaying the inspection screen provided to the checker terminal. The screen generator 12 outputs the screen data to the screen transmitter 13 together with the lane number. The screen data is data used to display at least a part of the inspection screen. For example, the screen data includes the vehicle number, the container number, and the seal number acquired by the number acquisition unit 11, and the data or program code necessary for displaying the interface for inputting the inspection result of the container. The inspection screen includes an interface for inputting the inspection result of the container of one truck to be inspected, but does not include an interface for allowing the gate clerk 6 to select one of the plurality of trucks.

The screen transmission unit 13 is a functional element that transmits screen data to the checker terminal 30 in order to display the inspection screen on the checker terminal 30. The screen data transmission method is not limited to one, and various methods are conceivable. The screen transmission unit 13 may transmit the generated screen data only to the checker terminal 30. In this case, the checker terminal 30 displays the inspection screen in which all the inspection results have not been input. Alternatively, the screen transmission unit 13 first transmits the screen data to the monitoring terminal 20, and the screen data returned from the monitoring terminal 20 in response to this transmission (data in which at least a part of the inspection result is input) is sent to the checker terminal 30. It may be transmitted (transferred). In this transfer, the screen transmission unit 13 may transmit screen data that further includes the camera image confirmed by the monitor 8 to the checker terminal 30. In this case, the gate clerk 6 can grasp the location where the observer 8 could not make a decision and can work efficiently. For example, the gate attendant 6 mainly inspects a portion having a rough image. Alternatively, the screen transmission unit 13 may transmit screen data indicating that all items are unchecked to both the checker terminal 30 and the monitoring terminal 20. When transmitting the screen data to the checker terminal 30, the screen transmission unit 13 refers to the lane database 41 to identify the terminal ID corresponding to the input lane number. Then, the screen transmission unit 13 transmits the screen data to the checker terminal 30 having the terminal ID.

FIG. 7 shows an example of the inspection screen generated and transmitted by the server 10. As described above, the inspection screen 50 is a screen for inputting the inspection result of the container of one truck photographed by the camera, and displays one combination of the vehicle number, the container number, and the seal number. FIG. 7 shows an example in which the OK button and the NG button are arranged corresponding to the container number, the seal number, and the individual sides of the container. The gate clerk 6 selects “OK” if there is no problem with the inspection item and “NG” if there is a problem with it. In FIG. 7, the selected button is shaded.

FIG. 7 also shows an example of the state transition of the inspection screen. More specifically, this example shows a state transition in a situation where the gate clerk 6 inspects the container at the entrance gate after the observer 8 inspects the container in the central control room 7. As described above, the inspection screen 50 does not include an interface for allowing the gate clerk 6 to select one track from a plurality of tracks (moving bodies). The left side of FIG. 7 shows the initial state of the inspection screen 50, and more specifically, the inspection screen 50 displayed on the monitoring terminal 20. The observer 8 inspects the appearance of the container within the range that can be seen from the camera image. The center of FIG. 7 shows that the observer 8 inspected the upper part, the left side face, and the front face of the container, and determined that there was no problem in these three places, and selected “OK”. Subsequently, the inspection screen 50 is transmitted to the checker terminal 30 and displayed. The gate staff 6 visually inspects the appearance of the container. The right side of FIG. 7 shows that the gate clerk 6 inspects the container number, the seal number, the right side surface and the rear surface of the container, determines that there is no problem in these items, and selects “OK”. The gate clerk 6 can omit the inspection for the item input on the monitoring terminal 20. Alternatively, the gate clerk 6 may also inspect the items input by the monitoring terminal 20, and may change the input by the monitoring member 8 if necessary.

The registration unit 14 is a functional element that registers the inspection result of the container in the container database 42. The registration unit 14 receives the inspection data (inspection result of the container) sent from the checker terminal 30 or the monitoring terminal 20, and updates the corresponding container information according to the inspection data. By this processing, the inspection result is registered in the container database 42.

When the inspection screen is provided only to the checker terminal 30, the registration unit 14 receives the inspection data from the checker terminal 30 to which the inspection result is input and executes the registration. Even if the inspection screen is first provided to the monitoring terminal 20 and then the inspection screen in which the input at the monitoring terminal 20 is reflected is provided to the checker terminal 30, the registration unit 14 receives the inspection data received from the checker terminal 30. To register.

When the inspection screen is transmitted to both the checker terminal 30 and the monitoring terminal 20 at the same timing, the registration unit 14 can separately receive the inspection data from these two terminals. In this case, the registration unit 14 preferentially registers the inspection data received from the checker terminal 30 in the container database 42. This means that the judgment of the gate clerk 6 who visually confirms the container has priority over the judgment of the surveillance staff 8 who visually judges the container. As an example, it is assumed that the registration unit 14 receives the inspection data from the checker terminal 30 after registering the inspection data received from the monitoring terminal 20 for a certain truck and container combination. In this case, the registration unit 14 overwrites the inspection result of the combination with the inspection data received from the checker terminal 30. As a result, the inspection result by the gate clerk 6 is registered in the item not inspected by the supervisor 8, and the item inspected by the monitor 8 is overwritten by the inspection result by the gate clerk 6. On the other hand, it is assumed that the registration unit 14 receives the inspection data from the monitoring terminal 20 after registering the inspection data received from the checker terminal 30 for a certain truck and container combination. In this case, the registration unit 14 registers the inspection data from the monitoring terminal 20 only in the item for which the inspection result in the checker terminal 30 is not registered. When the inspection results of the checker terminal 30 have already been registered in all the items, the registration unit 14 does not register the inspection data from the monitoring terminal 20 in the container database 42.

Next, the monitoring terminal 20 will be described. The monitoring terminal 20 includes an image display unit 21, a number confirming unit 22, and a screen control unit 23 as functional components.

The image display unit 21 is a functional element that displays an image captured by the camera 4. In the present embodiment, the image display unit 21 displays an image in which the surveillance staff 8 can visually recognize at least the vehicle number of the truck. When the entrance gate includes a plurality of lanes 2, the image display unit 21 may simultaneously display the images of the plurality of cameras 4 (that is, the images of the plurality of lanes 2). Alternatively, the image display unit 21 may sequentially display the camera images of the individual lanes 2 one by one.

When displaying the camera images in order, the image display unit 21 analyzes the camera image of each lane 2 to identify the lane 2 having the longest track row, and displays the camera image corresponding to the identified lane 2. It may be displayed in priority to the other lanes 2. Alternatively, when receiving the confirmation request from the checker terminal 30, the image display unit 21 may preferentially display the image of the camera 4 corresponding to the checker terminal 30 on another lane 2. The image display unit 21 refers to the lane database 41 and reads the lane number corresponding to the terminal ID included in the confirmation request, thereby specifying the lane 2 in which the image is to be displayed. Such priority display is intended to alleviate congestion in the lane 2, which is estimated to take a long time for inspection.

The number confirming unit 22 is a functional element that transmits the vehicle number input or confirmed by the monitor 8 to the server 10. The observer 8 confirms the vehicle number by looking at the license plate of the truck shown in the image displayed by the image display unit 21. Then, the monitor 8 inputs the vehicle number into the monitor terminal 20. In order to assist or omit the input operation of the surveillance staff 8, the number fixing unit 22 may analyze the image and display the vehicle number written on the license plate as text data. The observer 8 compares the vehicle number with the image, and if the analysis result is correct, the vehicle number is confirmed, and if the analysis result is incorrect, the error is corrected and the vehicle number is confirmed. When the monitor 8 inputs or confirms the vehicle number, the number confirming unit 22 transmits the vehicle number to the server 10.

If the vehicle number can be automatically recognized, the number confirming unit 22 transmits the vehicle number to the server without accepting the input of the surveillance staff 8, and only when an error occurs in the recognition, the surveillance staff 8 makes a decision. The vehicle number may be received and the vehicle number may be transmitted to the server 10. Alternatively, the number confirming unit 22 displays a plurality of vehicle numbers obtained via the antenna 5 from the vehicle-mounted devices of a plurality of trucks waiting in a certain lane 2 as options, and the monitor 8 is provided with the options. The vehicle number of the first truck shown in the camera image may be selected from among the above.

The screen control unit 23 is a functional element that receives the input of the inspection result. The screen control unit 23 receives the screen data sent from the server 10, processes the screen data, and displays the inspection screen. The observer 8 confirms the camera image displayed by the image display unit 21, inspects the appearance of the container within a range that can be understood from the image, and inputs the inspection result to the inspection screen. When the monitor 8 completes the input of the inspection result, the screen control unit 23 transmits the inspection data in which the input is reflected to the server 10.

Next, the checker terminal 30 will be described. The checker terminal 30 includes a notification unit 31 and a screen control unit 32 as functional components.

The notification unit 31 is a functional element that transmits a confirmation request, which is a signal for causing the surveillance staff 8 to confirm the image, to the surveillance terminal 20. The purpose of this signal is to prompt the watchman 8 to confirm the vehicle number of the truck in the lane corresponding to the checker terminal 30 (for example, a congested lane). When the gate clerk 6 operates the checker terminal 30 to instruct the request, the notification unit 31 generates a confirmation request including the terminal ID and transmits it to the server 10. In the server 10, the image display unit 21 switches the camera image according to the confirmation request. The checker terminal 30 may not include the notification unit 31.

The screen control unit 32 is a functional element that receives the input of the inspection result.

The gate clerk 6 in the lane 2 inspects the appearance of the container and inputs the result on the inspection screen, and the screen control unit 32 accepts the input (step S30). When the gate clerk 6 completes the input, the screen control unit 32 transmits the inspection data to the server 10 (step S31). The server 10 registers the inspection result by updating the container information in the container database 42 according to the inspection data (step S32).

FIG. 10 shows details of acquisition of the vehicle number. First, the image display unit 21 of the monitoring terminal 20 receives an image from the camera 4 and displays the image (step S41). The monitor 8 looks at the camera image and inputs or confirms the vehicle number. In response to this operation, the number confirmation unit 22 accepts the input or confirmation (step S42), and transmits the confirmed vehicle number to the server 10 (step S43). In the server 10, the number acquisition unit 11 receives the vehicle number, and this process corresponds to the above step S11 or step S21. After that, the processing of step S12 or later or step S22 or later described above is executed.

FIG. 11 shows a process of acquiring a vehicle number in response to a confirmation request from the checker terminal 30. In the checker terminal 30, the notification unit 31 transmits a confirmation request to the monitoring terminal 20 according to the operation of the gate clerk 6 (step S51). In response to the confirmation request, the image display unit 21 of the monitoring terminal 20 displays the camera image corresponding to the checker terminal 30 with priority over the camera image of the other lane 2 (step S52). The monitor 8 looks at the camera image and inputs or confirms the vehicle number. In response to this operation, the number confirmation unit 22 accepts the input or confirmation (step S53), and transmits the confirmed vehicle number to the server 10 (step S54).

The generation step and screen data for displaying the inspection screen on the checker terminal of the gate clerk. And a transmitting step of transmitting to the checker terminal.

In such an aspect, the checker terminal displays one moving object coming to the entrance gate as an inspection target from the beginning. Therefore, the gate clerk can immediately start the inspection of one mobile body (the mobile body displayed on the checker terminal) without selecting one from the plurality of mobile bodies. Inspecting the vehicle or cargo at the entrance gate is shortened because the gate clerk does not have to select the vehicle.

In the gate management system according to another aspect, the acquisition unit acquires the mobile body identifier input or confirmed by the surveillance staff who has confirmed the image of the mobile body taken by the camera at the entrance gate, and subsequently, Alternatively, the cargo identifier corresponding to the mobile unit identifier may be acquired. It is possible to provide accurate information about the moving body and the cargo to the gate staff by executing the acquisition of the cargo identifier and the subsequent processing triggered by the input or confirmation of the moving body identifier by the operation of the observer. it can. Since the gate clerk does not select the moving body on the inspection screen, it is important to accurately provide the gate clerk (checker terminal) with information on one moving body to be inspected. In addition, since the surveillance staff checks the images, it is not necessary to make the camera at the entrance gate highly accurate or to install another camera at a place where the license plate can be easily photographed. Therefore, the introduction cost of the gate management system can be suppressed. For example, the cost of the camera can be reduced as compared with the techniques of Patent Documents 2 and 3 described above in which it is necessary to recognize the vehicle number and the container number by analyzing the camera image.

In the gate management system according to another aspect, the transmission unit may transmit the screen data to the monitoring terminal so that the inspection screen is displayed on the monitoring terminal and the monitoring staff inputs the inspection result. Since the time and labor required for the gate staff to input the inspection result are reduced by the amount of the inspection person inputting the inspection result, it is expected that the inspection time of the moving body or cargo can be shortened. Since the observer only looks at the camera image, it can be inspected in a shorter time than the gate clerk who inspects while walking around the container. If the observer monitors a plurality of gates, the work at the entrance gate can be efficiently performed with a small number of personnel.
