Description

The present invention relates to a container terminal and its operation method, and more particularly to a container terminal and its operation method for improving cargo handling efficiency.

A container terminal has been proposed that detects the vehicle registration number of a foreign vehicle and issues a cargo handling command to a portal crane before the foreign vehicle that has passed through the gate arrives near one end of the storage lane for cargo handling ( For example, see Patent Document 1).

In this container terminal, foreign vehicles that have passed through the gate are divided according to destination and are made to stand by in the first waiting area. Therefore, when a plurality of foreign vehicles having different destinations enter at once, the foreign vehicle is congested when the vehicle registration number of the foreign vehicle is detected. Further, in this container terminal, the foreign vehicles are guided in order by making the foreign vehicles stand by a plurality of times before arriving at the cargo handling position where the cargo is handled from the gate. Therefore, the waiting time of the foreign vehicle was long. The congestion of foreign vehicles and the prolongation of waiting time are factors that reduce cargo handling efficiency.

Further, in the above container terminal, when the foreign vehicle arrives at the storage lane different from the instruction at the gate, the portal crane is temporarily put on standby at the cargo handling position of the foreign vehicle. The waiting time of this gantry crane is also a factor that reduces cargo handling efficiency.

On the other hand, since the outpatient vehicle 20 is not a dedicated vehicle for the container terminal 10, it is not equipped with a dedicated communication device, a position detection device, or the like. Therefore, the container terminal 10 of the present invention includes a yard detection device 41, a gate detection device 42, and a control device 43. While the outpatient vehicle 20 arrives at the target storage lane 14 using them, an outpatient command Cx for the outpatient vehicle 20 is issued to the portal crane 30. The period during which the foreign vehicle 20 arrives at the target storage lane 14 includes the period from the moment when the foreign vehicle 20 passes through the gate 13 to the moment when the foreign vehicle 20 arrives at the target storage lane 14.

Further, in the container terminal 10, the control device 43 is interposed between the communication between the management device 40 and the crane control device 36. Then, the control device 43 functions as a buffer for the cargo handling command transmitted from the management device 40 to the crane control device 36. The control device 43 accumulates the work occurring in the storage lane 14 as a buffer, and preferentially selects the work for the outpatient vehicle 20 from the work. The control device 43 is installed in the management building 17.

The yard detection device 41 is wirelessly or wiredly connected to the control device 43 so as to be able to communicate with each other. The yard detection device 41 is installed on the side of the outpatient approach road 24 extending from the entry of the outpatient vehicle 20 into the container yard 11 from the gate 13 to the arrival in the outpatient lane 25. In this embodiment, a plurality of yard detection devices 41 are installed in the vicinity of one end of each storage lane 14. That is, each yard detection device 41 is installed on the side of the end point of the outpatient approach path 24, which is located before entering the outpatient lane 25. The gate detection device 42 is wirelessly or wiredly connected to the management device 40 so as to be able to communicate with each other. The gate detection device 42 is arranged at each gate 13.

The yard detection device 41 and the gate detection device 42 detect the vehicle-specific identification information Nx provided in advance by the outpatient vehicle 20. In this embodiment, the yard detection device 41 and the gate detection device 42 are roadside devices of the electronic toll collection system, and are wirelessly connected to the on-board unit 44 of the electronic toll collection system provided in advance in the passing foreign vehicle 20. Communicate. Then, the yard detection device 41 and the gate detection device 42 read the unique vehicle-mounted device number stored in the vehicle-mounted device 44 as the identification information Nx. The on-board unit 44 can transmit the on-board unit number by wirelessly communicating with the yard detection device 41 and the gate detection device 42 even if the card in which the electronic charge is stored is not inserted.

A yard breaker 45 and a yard indicator 46 are installed in the vicinity of the yard detection device 41, and these are connected to the control device 43 so as to be able to communicate wirelessly or by wire. The yard barrier 45 is, for example, a mechanism for raising and lowering the barrier rod in conjunction with the yard detection device 41, and blocks and releases the entry into the outpatient lane 25. The yard indicator 46 is, for example, an electric bulletin board system, and in conjunction with the yard detection device 41, instructs the driver of the outpatient vehicle 20 of the cargo handling position.

A gate barrier 47 and a gate indicator 48 are installed at the gate 13, and these are connected to the management device 40 so as to be able to communicate wirelessly or by wire. The gate barrier 47 is, for example, a mechanism in which the barrier rod moves up and down in conjunction with the gate detection device 42, and blocks and releases the gate 13. The gate indicator 48 is, for example, an electric bulletin board, and instruct the driver of the outpatient vehicle 20 of the cargo handling position in conjunction with the gate detection device 42. As the gate indicator 48, for example, a printing machine that prints a printed matter in which the cargo handling position Qx of the outpatient vehicle 20 is described may be used.

FIG. 4 illustrates the flow of control signals in the container terminal 10. The management device 40 and the control device 43 are composed of a CPU that performs various information processing, an internal storage device that can read and write programs and information processing results used for performing the various information processing, and various interfaces.

The internal storage device of the management device 40 stores the control number Mx, the storage position Px, the cargo handling position Qx, and the outpatient command Cx associated with the identification information Nx of the outpatient vehicle 20.

The identification information Nx is the vehicle-mounted device number of the vehicle-mounted device 44 in this embodiment. The control number Mx is a unique number of the container C, and may include an owner code and a number indicating the size and type of the container C. The storage position Px is a storage position in the container yard 11 of the container C, and is a lane number (position of the storage lane 14), a bay number (longitudinal direction (y direction) of the storage lane 14), and a row number (side of the storage lane 14). It consists of a direction (x direction)) and a tier number (height direction (z direction) of the storage lane 14). The cargo handling position Qx is the cargo handling position of the outpatient vehicle 20 and the premises vehicle 21, and is a lane number and a bay number, an external address, a quay crane 16 number, and the like. The outpatient command Cx is a command for the cargo handling work performed by the gantry crane 30 generated in the storage lane 14 to handle the cargo handling of the container C for the outpatient vehicle 20, and is in a pending state (flag is OFF) by the management device 40. State) is generated.

The management device 40 has a control number My associated with the identification information Ny of the premises vehicle 21, a storage position Py, a cargo handling position Qy, a premises command Cy, and a movement of the container C in the container yard 11 in the internal storage device. The control number Mz, the storage position Pz, the cargo handling position Qz, and the yard command Cz are also stored. The yard command Cy and the yard command Cz are also generated in the hold state (OFF state).

In the control device 43, the pending cargo handling command transmitted from the management device 40 to the internal storage device is classified and received for each storage lane 14 in which the storage position of the container C subject to the cargo handling command exists. It is stored in order. That is, a plurality of cargo handling commands generated in the same storage lane 14 are stored in the internal storage device of the control device 43.

Priorities are set for each of the cargo handling commands stored in the control device 43. The priority is set lower in the order of the premises command Cy, the outpatient command Cx, and the yard command Cz, and the yard command Cy has the highest priority. Further, in the same cargo handling command, the earlier the cargo handling command is received, the higher the priority is set.

The pending state of the outpatient command Cx is that when the outpatient vehicle 20 arrives near one end of the storage lane 14 and enters the outpatient lane 25, that is, the identification information Nx is detected by the yard detection device 41. It is released when the flag is turned on (flag is turned on). The hold state of the premises command Cy is released (turned on) when the premises vehicle 21 arrives near one end of the storage lane 14 and enters the outpatient lane 25. The hold state of the yard command Cz is a state in which the portal crane 30 is not operated by the premises command Cy and the outpatient command Cx, that is, the storage has the same number of received the outpatient command Cx and the premises command Cy. It is released (turned on) when the number of portal cranes 30 in lane 14 is less than the number.

In the gantry crane 30, the hold state of the plurality of cargo handling commands classified for each storage lane 14 stored in the control device 43 is released, and the high priority cargo handling command is transmitted to the crane control device 36. Then, automatic traveling is performed based on the cargo handling command.

For example, in FIG. 4, in the storage lane 14 of lane number 1, three cargo handling commands are received in the order of the yard command Cz, the outpatient command Cx, and the premises command Cy, and the hold state of the outpatient command Cx is released. It is (turned on). In this case, the control device 43 transmits only the outpatient command Cx to the crane control device 36.

In the storage lane 14 of lane number 2, four cargo handling commands are received in the order of outpatient command Cx, yard command Cz, yard command Cy, and yard command Cy, and the outpatient command Cx and the fourth are received. The hold status of the yard command Cy has been released (turned on). In this case, the control device 43 preferentially transmits the premises command Cy for which the hold state has been released to the crane control device 36, and then transmits the outpatient command Cx to another crane control device 36. In this way, when there are a plurality of cargo handling commands that can be transmitted to the same storage lane 14, the control device identifies the portal crane 30 that transmits the cargo handling commands based on predetermined conditions. The conditions are set based on the high priority and the high cargo handling efficiency, and in the storage lane 14 of the lane number 2, the portal crane 30 to which the premises command Cy can be preferentially processed is specified. The cargo handling efficiency can be determined, for example, from the fact that the gantry crane 30 does not process the cargo handling command and that the gantry crane 30 is close to the cargo handling position Qx.

In the storage lane 14 of lane number 3, two cargo handling commands are received in the order of the yard command Cz and the outpatient command Cx, and the hold state of the yard command Cz is released (turned on). In this case, the control device 43 transmits only the yard command Cz to the crane control device 36.

The operation method of the container terminal 10 will be described below with reference to the flowcharts illustrated in FIGS. 5 to 7. Specifically, after the foreign vehicle 20 carrying the container C from the outside arrives at the gate 13, the container C is stored in the storage lane 14 of the lane number 1, and the foreign vehicle 20 moves from the gate 13 to the outside. The flow up to departure will be described as an example.

5 and 7 show a schematic flow when the foreign vehicle 20 passes through the gate 13, and FIG. 6 illustrates a schematic flow when the foreign vehicle 20 arrives near one end of the storage lane 14.

As illustrated in FIG. 5, when the foreign vehicle 20 arrives at the gate 13 blocked by the gate barrier 47 from the outside, the gate detection device 42 detects the identification information Nx from the on-board unit 44 of the foreign vehicle 20. (S10). Next, the management device 40 associates the detected identification information Nx with the control number Mx of the container C carried by the outpatient vehicle 20, the storage position Px, the cargo handling position Qx, and the outpatient command Cx (S20). The outpatient command Cx is generated in the hold state (OFF) based on the storage position Px.

Next, the management device 40 permits the outpatient vehicle 20 to enter the container yard 11 (S30), the management device 40 transmits the outpatient command Cx (S40), and the control device 43 sends the outpatient command Cx. Receive Cx (S50). Specifically, the following steps are processed in parallel.

As a step (S30) for permitting entry, the management device 40 displays the cargo handling position Qx associated with the identification information Nx on the gate indicator 48, and instructs the driver of the outpatient vehicle 20 to indicate the cargo handling position Qx. .. Next, the management device 40 raises the blocking rod of the gate barrier 47 to release the blocking of the gate 13. When this step is completed, the foreign vehicle 20 passes through the gate 13 and enters the container yard 11. Then, the outpatient vehicle 20 travels along the outpatient travel path 22 toward the storage lane 14 instructed by the management device 40.

On the other hand, as a step regarding the outpatient command Cx, the management device 40 transmits the outpatient command Cx to the control device 43 in a pending state (S40). Next, the control device 43 classifies the received outpatient command Cx into each storage lane 14 in which the storage position Px of the container C to be handled by the outpatient command Cx exists (S50). Next, the control device 43 stores the outpatient command Cx in the internal storage device at the end of the order, and arranges the cargo handling command generated for the same storage lane 14 in the order in which it is received. (S60).

When the two parallel steps are completed as described above, the process returns to the start and functions similarly for the next outpatient vehicle 20.

In this way, when the outpatient vehicle 20 enters the container yard 11, the management device 40 sequentially creates an outpatient command Cx for the outpatient vehicle 20 arriving at the gate 13 from the outside, and the control device 43. The outpatient command Cx is sent to. Then, the control device 43 receives the outpatient command Cx for the outpatient vehicle 20 before the outpatient vehicle 20 arrives near one end of the storage lane 14 which is the target of the cargo handling position Qx instructed by the management device 40. And store it once. That is, the control device 43 functions as a buffer.

As a result, low-priority work such as rearranging the container C in the storage lane 14 can be postponed and the cargo handling of the outpatient vehicle 20 can be prioritized, so that the waiting time of the outpatient vehicle 20 at the cargo handling position Qx can be shortened. Will be advantageous to. Further, if the cargo handling of the premises vehicle 21 occurs at this time, the cargo handling of the premises vehicle 21 is prioritized over the cargo handling of the outpatient vehicle 20, so that the waiting time of the premises vehicle 21 at the cargo handling position Qx can be shortened. Will be advantageous. That is, it is possible to improve the efficiency of a plurality of cargo handling operations generated in the container yard 11, so that the work efficiency of the gantry crane 30 can be improved.

The outpatient vehicle 20 that has passed through the gate 13 arrives at the end point of the outpatient approach road 24 in which the entry to the outpatient lane 25 is blocked by the yard barrier 45. At this time, as illustrated in FIG. 6, the yard detection device 41 installed on the side of the end point thereof detects the identification information Nx from the on-board unit 44 of the arriving foreign vehicle 20 (S100).

Next, the control device 43 is one end of the storage lane 14 in which the arriving foreign vehicle 20 is instructed by the management device 40 based on the control number Mx (storage position Px, cargo handling position Qx) associated with the detected identification information Nx. It is determined whether or not the vehicle has arrived in the vicinity of the unit (S110).

In this step, if it is determined that the foreign vehicle 20 has not arrived, that is, the foreign vehicle 20 has arrived at the erroneous storage lane 14, the control device 43 prohibits the foreign vehicle 20 from entering the foreign vehicle lane 25. (S120). Specifically, the control device 43 maintains the barrier at the entrance of the outpatient lane 25 by the yard barrier 45. Further, the control device 43 displays the cargo handling position Qx associated with the identification information Nx, that is, the correct lane number on the yard indicator 46, and instructs the driver of the outpatient vehicle 20 to handle the cargo handling position Qx.

On the other hand, when it is determined in the above step that the crane has arrived, the control device 43 permits the outpatient vehicle 20 to enter the outpatient lane 25 (S130) and issues an outpatient command Cx to the portal crane 30. (S140 to S170). Specifically, the following steps are processed in parallel.

As a step (S130) of permitting the outpatient vehicle 20 to enter the outpatient lane 25, the control device 43 displays the cargo handling position Qx associated with the identification information Nx, that is, the bay number on the yard indicator 46. The driver of the outpatient vehicle 20 is instructed to handle the cargo handling position Qx. Next, the control device 43 raises the blocking rod of the yard barrier 45 to release the blocking of the approach to the outpatient lane 25. When this step is completed, the outpatient vehicle 20 enters the outpatient lane 25 and travels along the outpatient lane 25 toward the cargo handling position Qx instructed by the management device 40.

As a step (S140 to S170) of issuing the outpatient command Cx to the portal crane 30, the control device 43 releases (turns on) the hold state of the outpatient command Cx based on the detected identification information Nx (S140). ). Next, the control device 43 selects a high-priority outpatient command Cx from the cargo handling commands generated in the same storage lane 14 and whose holding state is released (S150). Next, the control device 43 identifies the gantry crane 30 that transmits the outpatient command Cx based on a predetermined condition (S160). In this embodiment, as illustrated in FIG. 3, the illustrated portal crane 30 is not currently processing a cargo handling command having a higher priority than the outpatient command Cx, and the storage position Px and the storage position Px and Close to the cargo handling position Qx. Next, the control device 43 transmits the selected outpatient command Cx to the crane control device 36 of the specified portal crane 30 (S170).

Next, the control device 43 waits until the remote control of the portal crane 30 by the crane operator is completed, and transmits to the management device 40 that the outpatient command Cx is completed based on the completion of the remote control. (S180). When the completion of the outpatient command Cx is transmitted as described above, the process returns to the start and functions similarly for the next outpatient vehicle 20.

The operation until the remote control of the gantry crane 30 is completed is as follows. The outpatient vehicle 20 permitted to enter the outpatient lane 25 travels to the cargo handling position Qx instructed by the management device 40, and stops at the cargo handling position Qx. Further, the gantry crane 30 that has received the outpatient command Cx automatically travels to the cargo handling position Qx by the crane control device 36 based on the outpatient command Cx, and stops at the cargo handling position Qx.

When the specified gantry crane 30 arrives at the cargo handling position Qx, the control by the crane control device 36 is switched to the remote control by the remote control device 37 by the crane operator. Specifically, the container C and the outpatient vehicle 20 are photographed by a camera installed in the gantry crane 30, and this image is displayed on the monitor of the management building 17. The crane operator handles the container C by remote control by the controller while checking the images of the container C and the outpatient vehicle 20 displayed on the monitor. After the portal crane 30 arrives at the cargo handling position Qx, the automatic control is switched to remote control, but the foreign vehicle 20 does not have to arrive at the cargo handling position Qx at the timing of the switching. Further, a device for detecting whether or not the outpatient vehicle 20 has stopped below the gantry crane 30, that is, at the cargo handling position Qx may be provided in either the gantry crane 30 or the outpatient lane 23.

The outpatient vehicle 20 resumes traveling toward the exit gate 13 when the container C mounted on the outpatient vehicle 20 is lifted by the hanging tool 32 and the hanging tool 32 rises to a predetermined height. After the container C is stored in the storage position P1 of the storage lane 14, the gantry crane 30 ends the remote control by the crane operator when the hanger 32 rises to a predetermined height.

When the remote control by the crane operator is completed, the portal crane 30 starts automatic traveling by the crane control device 36 based on the cargo handling command newly transmitted from the control device 43.

In this way, the container terminal 10 detects the identification information Nx of the foreign vehicle 20 while the foreign vehicle 20 passing through the gate 13 arrives at the storage lane 14 for cargo handling, and is based on the detected identification information Nx. Since the outpatient command Cx is issued to the gate-type crane 30, the gate-type crane 30 can start cargo handling only for the outpatient vehicle 20 that arrives as instructed. This is advantageous in avoiding the start of cargo handling of the portal crane 30 for the foreign vehicle 20 that is different from the instruction or the foreign vehicle 20 that has not arrived, and the useless waiting time of the portal crane 30 can be shortened.

Further, until the outpatient vehicle 20 passes through the yard detection device 41, the outpatient vehicle 20 travels on the outpatient approach road 24 in any order without waiting at an intermediate position, so that the arrival time of the outpatient vehicle 20 in the storage lane 14 Can be shortened. Along with these, cargo handling efficiency can be improved.

Further, since the foreign vehicle 20 travels freely in order until it passes through the yard detection device 41, even if the order of the foreign vehicle 20 is changed with respect to the passing order of the gate 13 after passing through the gate 13, the portal crane 30 Can start cargo handling only for the outpatient vehicle 20 that arrived as instructed.

Further, while the foreign vehicle 20 passing through the gate 13 arrives at the storage lane 14 for cargo handling, the identification information Nx of the foreign vehicle 20 is detected, and the gate crane 30 is outpatient based on the detected identification information Nx. Issue command Cx. That is, the gantry crane 30 can receive the outpatient command Cx for the outpatient vehicle 20 before the outpatient vehicle 20 arrives at the predetermined cargo handling position Qx in the storage lane 14. As a result, it becomes advantageous for the foreign vehicle 20 to quickly handle the cargo of the container C with respect to the foreign vehicle 20 after arriving at the cargo handling position Qx of the storage lane 14, and the waiting time of the foreign vehicle 20 in the container yard 11 is shortened. , The cargo handling efficiency can be improved. The control device 43 performs the above processing on the plurality of storage lanes 14 at the same time.

Further, the container terminal 10 uses the control device 43 as a buffer for the outpatient command Cx, the premises command Cy, and the yard command Cz. That is, each command is transmitted to the control device 43 in the hold state without directly instructing the portal crane 30 from the management device 40, and when the hold state is released, the priority of each command is changed. It is transmitted from the control device 43 to the portal crane 30 based on the height. As a result, high-priority commands (for example, yard command Cy for the premises vehicle 21) are proactively processed from the work occurring in the same storage lane 14, and the cargo handling work generated in the container yard 11 is streamlined. can do. Along with this, the work efficiency of the gantry crane 30 can be improved, and the cargo handling efficiency can be improved.

In addition, the container terminal 10 can reduce the information processing load of each of the cargo handling by processing the cargo handling by both the management device 40 and the control device 43, which is advantageous for speeding up the information processing.

In this embodiment, since the storage lane 14 having the lane number 1 is taken as an example, the outpatient command Cx is selected as the cargo handling command having the hold state released and having a high priority. For example, in the storage lane 14 of lane number 2, the premises command Cy is first selected as a cargo handling command whose hold state is released and has a high priority, and then the outpatient command Cx is selected. Further, in the storage lane 14 of the lane number 3, the yard command Cz is selected as a cargo handling command having a high priority and the hold state is released.

That is, the container terminal 10 preferentially processes the cargo handling command in which the hold state is released from the work occurring in the same storage lane 14 by the control device 43, and the yard command is based on the high priority. Cy, outpatient command Cx, and yard command Cz can be processed in this order with priority. This is advantageous for promptly processing the premises command Cy, and the berthing time of the container ship 15 can be shortened. Along with this, cargo handling efficiency can be improved.

As illustrated in FIG. 7, when the foreign vehicle 20 arrives at the gate 13 blocked by the gate barrier 47 from the container yard 11, the gate detection device 42 receives the identification information Nx from the in-vehicle device 44 of the foreign vehicle 20. Is detected (S200). Next, the management device 40 determines whether or not the outpatient command Cx associated with the identification information Nx has been completed (S210).

If it is determined in this step that it has not been completed, the management device 40 prohibits the outpatient vehicle 20 from leaving the outside (S220). Specifically, the management device 40 maintains the gate 13 shut off by the gate barrier 47. Further, the management device 40 displays the cargo handling position Qx associated with the identification information Nx on the gate indicator 48, and instructs the driver of the outpatient vehicle 20 to indicate the cargo handling position Qx.

On the other hand, when it is determined in the above step that the process is completed, the management device 40 permits the outpatient vehicle 20 to leave the outside (S230), and detects the identification information Nx, the management number Mx of the container C, and the storage. The association with the position Px and the cargo handling position Qx is released (S240).

As a step (S230) for permitting the outpatient vehicle 20 to leave the outside, the management device 40 raises the blocking rod of the gate barrier 47 to release the blocking of the gate 13. At this time, if the management device 40 manages the cargo handling position outside the outpatient vehicle 20, the cargo handling position may be displayed on the gate indicator 48. When this step is completed, the foreign vehicle 20 passes through the gate 13 and exits to the outside.

After processing the step (S240) of canceling the association, the management device 40 stores the identification information Nx, the control number Mx, the storage position Px, the cargo handling position Qx, and the outpatient command Cx as a history in the internal storage device.

When the step is completed as described above, the process returns to the start and functions similarly for the next outpatient vehicle 20. In this way, when the outpatient vehicle 20 leaves the outside, the management device 40 cancels the association between the identification information Nx and the management number Mx.

That is, the identification information Nx of the outpatient vehicle 20 is associated with the control number Mx each time. As a result, when the foreign vehicle 20 arrives at the container terminal 10 again, the identification information Nx is associated with the new control number Mx.

As described above, the container terminal 10 generates a cargo handling command for the outpatient vehicle 20 and the premises vehicle 21 in the vicinity of the gate 13 or in the cargo handling area 12 of the ship, and temporarily stores the cargo handling command in the control device 43. Then, the control device 43 issues a cargo handling command to the gantry crane 30 while the outpatient vehicle 20 and the premises vehicle 21 arrive at the storage lane 14, so that the gantry crane 30 is earlier than the conventional one. You can receive cargo handling orders. As a result, when the outpatient vehicle 20 or the premises vehicle 21 arrives at a predetermined position in the storage lane 14, it becomes advantageous to quickly handle the cargo of the container C for them, and the outpatient vehicle 20 or the premises vehicle at the cargo handling position Qx becomes advantageous. The waiting time of 21 can be shortened. Along with this, cargo handling efficiency can be improved.

Specifically, in the storage lane 14 in which the storage position Px of the container C to be handled by the outpatient vehicle 20 exists, the outpatient command Cx is more than the yard command Cz for rearranging the container C in the storage lane 14. have priority. Therefore, the gantry crane 30 can also arrive at a predetermined position before the foreign vehicle 20 arrives at the predetermined position in the storage lane 14 to prepare for cargo handling with respect to the foreign vehicle 20. Even if the gantry crane 30 is working in accordance with the yard command Cz, the yard command Cz is forcibly terminated by generating the outpatient command Cx at an early stage or releasing the hold state. You may let me.

Moreover, by setting the priority of the premises command Cy higher than that of the outpatient command Cx, the cargo handling for the premises vehicle 21 can be processed with priority over the cargo handling for the outpatient vehicle 20. As a result, the berthing time of the container ship 15 can be shortened, which is advantageous for accepting a larger number of container ships 15.

Further, the container terminal 10 uses the vehicle-specific identification information Nx provided in advance in the foreign vehicle 20, so that a dedicated wireless tag, a mobile terminal, and a large number of receivers that communicate with them are not required. This makes it possible to simplify the approach work of the foreign vehicle 20 at the gate 13. Further, in the yard detection device 41, it is sufficient to install at most as many storage lanes 14 in the area of the container yard 11, and the cost is compared with the case where the receivers are installed in the entire area of the container yard 11. Can be reduced. In addition, since no major layout change is required and installation work is minimized, it can be easily applied to existing ones.

In this embodiment, when the outpatient vehicle 20 passes through the gate 13 or enters the storage lane 14 by using the roadside device of the electronic toll collection system as the yard detection device 41 and the gate detection device 42. It is possible to detect the unique in-vehicle device number of the in-vehicle device 44 as the identification information Nx without slowing down the speed. This is advantageous in shortening the travel time of the outpatient vehicle 20.

For the yard detection device 41 and the gate detection device 42, for example, a license plate provided in advance of the outpatient vehicle 20 or an imaging device for imaging the exterior may be used. When an imaging device is used, the identification information Nx is a vehicle-specific vehicle registration number written on the imaged license plate, or the shape and color of the exterior.

When detecting the vehicle registration number as the identification information Nx, the yard detection device 41 and the gate detection device 42 may use a camera that captures the front or rear surface of the outpatient vehicle 20. When the outpatient vehicle 20 is a container trailer, the automobile registration number written on the license plate attached to the front surface and the automobile registration number written on the license plate attached to the rear surface are different. Therefore, it is preferable that the gate detection device 42 uses both a front image pickup device that images the front surface of the outpatient vehicle 20 and a rear surface image pickup device that images the rear surface. In this case, it is possible to surely avoid missing the automobile registration number, and both the front and rear automobile registration numbers can be used as the identification information Nx. As a result, since either the front image pickup device or the rear surface image pickup device may be used as the yard detection device 41, the degree of freedom in the installation position of the yard detection device 41 is increased.

When the exterior is detected as the identification information Nx, the yard detection device 41 and the gate detection device 42 are preferably cameras that image the side surface or the upper surface of the exterior of the outpatient vehicle 20 having a large surface area. By imaging the side surface or the upper surface having a large surface area in this way, the difference in the exterior of the outpatient vehicle 20 becomes clearer. In particular, the yard detection device 41 and the gate detection device 42 may use a camera that images the upper surface of the outpatient vehicle 20. When the portal crane 30 is remotely controlled, the crane operator can confirm the outpatient vehicle 20 by displaying the image of the upper surface of the outpatient vehicle 20 on the monitor installed in the management building 17.

Further, the yard detection device 41 and the gate detection device 42 may use a reader that communicates with the RFID tag provided in advance in the outpatient vehicle 20 and reads the identification information Nx stored in the RFID tag. In this case, when the foreign vehicle 20 arrives at the container terminal 10 for the first time, the RFID tag is delivered at the gate 13, but the delivery work can be omitted from the second time onward. As the RFID tag, a passive tag that does not have a built-in battery is preferable.

In this embodiment, by installing the yard detection device 41 for each storage lane 14, it is possible to identify that the outpatient vehicle 20 has arrived at the target storage lane 14. This is advantageous for confirming whether or not the outpatient vehicle 20 has arrived at the storage lane 14 instructed by the management device 40, and it is possible to avoid transmitting an erroneous outpatient command Cx. Along with this, the gantry crane 30 can always handle the foreign vehicle 20 arriving as instructed, so that the wasteful waiting time can be shortened and the cargo handling efficiency can be improved.

Further, by installing the yard barrier 45 and the yard indicator 46 interlocking in the vicinity of the yard detection device 41, the number of outpatient vehicles 20 entering the outpatient lane 25 can be limited. In this way, assuming that the number of outpatient vehicles 20 entering the outpatient lane 25 is one, the cargo handling for the outpatient vehicle 20 is processed in the order in which the outpatient vehicle 20 arrives in the same storage lane 14. Will be done. This is advantageous for avoiding the occurrence of traffic congestion due to the plurality of outpatient vehicles 20 at the midway position of the outpatient lane 25. When the outpatient vehicle 20 arrives at the erroneous storage lane 14, the control device 43 can notify the driver of the outpatient vehicle 20 to that effect by using the yard indicator 46. As a result, it is possible to avoid a situation in which the outpatient vehicle 20 waits for a long time at an erroneous position, which is advantageous for improving cargo handling efficiency.

In this embodiment, the configuration in which the management device 40 transmits a cargo handling command in the pending state to the control device 43 has been described as an example. This is a case where the digging work has not occurred in the container C which is the target of this cargo handling command. When digging up work occurs in the container C that is the target of the cargo handling command, it is desirable that the management device 40 transmits the cargo handling command in which the hold state is released to the control device 43.

As a result, the cargo handling command including the digging work is transmitted to the crane control device 36 of the gantry crane 30 immediately after being arranged in the control device 43 in a state where the holding state is released. As a result, since the digging work is started promptly after the cargo handling command is issued, the waiting time of the outpatient vehicle 20 and the premises vehicle 21 due to the digging work can be significantly shortened.

The premises command Cy is a control device from the management device 40 when the yard vehicle 21 is detected by the yard detection device 41 or the premises vehicle detection device after the association is made on the container ship 15. It has been transmitted to 43. For example, in the container ship 15, the premises vehicle 21 and the container C handled by the premises vehicle 21 are associated with each other by using the handy terminal carried by the worker or the in-vehicle terminal mounted on the premises vehicle 21. It is good. Further, when the premises vehicle 21 passes a predetermined point when heading from the ship's cargo handling area 12 to the container yard 11, the detection device for the premises vehicle may be installed at that point.

The container terminal 10 of the second embodiment illustrated in FIG. 8 is different from the first embodiment in the number of yard detection devices 41 and the installation location thereof. The yard detection device 41 of this embodiment is one unit, and is installed on the side of the end of the outpatient approach road 24 on the gate 13 side. Further, the yard barrier 45 and the yard indicator 46 are not installed in the vicinity of the yard detection device 41. However, in this embodiment, the foreign vehicle 20 can travel in any order until it passes through the yard detection device 41, but after passing through the yard detection device 41, it is necessary to travel in the order of passage of the yard detection device 41. ..

In this embodiment, the outpatient command Cx is transmitted to the specified gantry crane 30's crane control device 36 in the order in which the outpatient vehicle 20 passes by the side of the yard detection device 41. Since the foreign vehicle 20 can run smoothly without stopping in the container yard 11 due to a barrier or the like, it is advantageous in shortening the moving time of the foreign vehicle 20.

Further, in this embodiment, since the yard detection device 41 detects the identification information Nx of the outpatient vehicle 20 closer to the gate 13, the hold state of the outpatient command Cx can be released earlier. As a result, the waiting time of the outpatient vehicle 20 in the container yard 11 can be effectively shortened, which is advantageous in improving the cargo handling efficiency.

In addition, the number of yard detection devices 41 installed in the container yard 11 can be reduced, which is advantageous in reducing the cost.

In the first embodiment, similarly to this embodiment, it is not necessary to install the yard barrier 45 and the yard indicator 46 in the vicinity of the yard detection device 41. By not installing the yard barrier 45, the number of outpatient vehicles 20 cannot be limited, while the temporary standby time of the outpatient vehicle 20 can be shortened. It is also possible to allow a plurality of outpatient vehicles 20 to enter the outpatient lane 25.

In the above-described embodiment, the container terminal 10 in which the outpatient vehicle 20 and the premises vehicle 21 travel on the side of the storage lane 14 has been described as an example, but the present invention is not limited thereto. For example, a reciprocating trolley is installed on the side of the storage lane 14, and the reciprocating trolley reciprocates on the side of the storage lane 14 from one end to the other end to carry the container C. Can also be applied to. In such a container terminal, the outpatient vehicle 20 stops in a region adjacent to one end of the storage lane 14 in the longitudinal direction, and the premises vehicle 21 stops in a region adjacent to the other end in the longitudinal direction. That is, the yard detection device 41 is configured to detect the identification information Nx while the outpatient vehicle 20 arrives at the region adjacent to the one end portion of the storage lane 14 in the longitudinal direction.
