Abstract
Description
[[Technical Field]]
[0001] The present invention relates to a terminal having cargo handling equipment using hydrogen gas as fuel, and a management system and management method for managing the cargo handling equipment, and more particularly to a terminal, a management system and a management method that can suppress a decrease in cargo handling efficiency. [[Background Art]]
[0002] Various container terminals with reduced carbon dioxide emissions have been proposed (see, for example, Patent Document 1). Patent Document 1 discloses the configuration of a gantry crane that operates by receiving electric power supplied from a trolley wire laid in a container terminal. By electrifying cargo handling equipment such as gantry cranes, carbon dioxide emissions at container terminals can be suppressed.
[0003] When laying a trolley wire in an existing container terminal, there is a problem that cargo handling work cannot be performed for a long period of time. On the other hand, it has been studied to suppress carbon dioxide emissions by changing the fuel of gantry cranes to hydrogen gas.
[0004] Since hydrogen gas has lower calorie per volume than light oil, the gantry crane may run out of fuel during cargo handling work. In addition, the frequency of fuel supply work for gantry cranes is higher with hydrogen gas than with light oil. When the fuel of a gantry crane is changed to hydrogen gas, there is a possibility that cargo handling efficiency at the container terminal may decrease.

[0012] Hereinafter, a terminal, a management system, and a management method will be described based on the embodiments shown in the drawings.
[0013] As illustrated in FIG. 1, a terminal 1 includes a plurality of storage lanes 3 where containers 2 are stored, and a quay 5 where a container ship 4 berths. The containers 2 are handled by cargo handling equipment 6. The cargo handling equipment 6 includes, for example, a quay crane 6a disposed on the quay 5, a gantry crane 6b traveling along the storage lanes 3, and an intra-terminal chassis 6c traveling within the terminal 1. In the present specification, the cargo handling equipment 6 is not limited to those described above, and any equipment used for cargo handling may be used, and this is a concept including, for example, straddle carriers, forklifts, top lifters, and reach stackers. The cargo handling equipment 6 may be manned cargo handling equipment 6 operated directly or remotely by an operator, or may be unmanned cargo handling equipment 6 controlled by automatic control.
[0014] A plurality of pieces of the cargo handling equipment 6 are configured to operate using hydrogen gas as fuel. The cargo handling equipment 6 has, for example, a fuel cell, or a mechanism combining a hydrogen engine and a generator, for example. In the terminal 1, this is not limited to the case where all the cargo handling equipment 6 uses hydrogen gas as fuel. A configuration may be adopted in which some pieces of the cargo handling equipment 6 operate with electricity supplied from a power supply cable, and other pieces of the cargo handling equipment 6 operate using hydrogen gas as fuel.
[0015] The terminal 1 includes a management building 7, and a gate 9 that manages entry and exit of external chassis 8. A management system 10 that manages work schedules for the cargo handling equipment 6 is installed in the management building 7. In FIG. 1, the management system 10 is indicated by a broken line for explanation.
[0016] Terminal 1 is equipped with multiple supply devices 11 for supplying hydrogen gas to cargo handling equipment 6. The supply devices 11 consist of, for example, mobile supply devices 11a having a vehicle equipped with a hydrogen tank. The mobile supply devices 11a can move to the vicinity of the cargo handling equipment 6 and supply hydrogen gas. The supply devices 11 may also consist of, for example, fixed supply devices 11b having a dispenser fixed to the ground surface and a hydrogen tank. The fixed supply devices 11b can supply hydrogen gas to the cargo handling equipment 6 that has moved.
[0017] The terminal 1 of the present invention is not limited to a container terminal. Terminal 1 includes quays for shipping products from steel mills, etc., and quays for bulk cargo such as coal.
[0018] As illustrated in Figure 2, the management system 10 can be configured using various known computers. The management system 10 includes a central processing unit (CPU) 12, main memory 13, auxiliary storage (e.g., HDD) 14, input units (keyboard 15, mouse), and output units (display 16, printer). By adding functions to a conventional management system or modifying the program, it can be used as the management system 10 of the present invention.
[0019] The processes performed by the management system 10 will be explained with reference to the flow shown in Figure 3. The following explanation will use the case where the cargo handling equipment 6 is a gantry crane 6b as an example. When the management system 10 starts processing (start), a large amount of cargo handling operation data is first read in the reading step S1. Specifically, cargo handling operation data is read from the auxiliary storage unit 14 to the main storage unit 13. Cargo handling operation data may be created by the management system 10 based on the scheduled departure and arrival dates and times of transport equipment such as container ships 4 and foreign chassis 8, and the scheduled number of goods to be entered and exited in storage facilities such as storage lanes 3. In this case, the scheduled departure and arrival dates and times of transport equipment are read from the auxiliary storage unit 14 to the main storage unit 13 in the reading step S1, and the main storage unit 13 and the central processing unit 12 create the cargo handling operation data.
[0020] As illustrated in Figure 4, the cargo handling data includes the container number of container 2, the location of container 2 in storage lane 3, and the details of the work. The work item names, such as 1 and 2, may also be included in the cargo handling data.
[0021] For example, in work item 1, the gantry crane 6b will be used to transport container 2, XXXU1234567, in a 3-lane, 2-column, 5-row, 3-tier configuration, to the outside chassis 8. In work item 2, the gantry crane 6b will be used to transport container 2, YYYU2345679, in a 5-lane, 3-column, 4-row, 5-tier configuration, from the outside chassis 8. The positions of container 2 are defined using the following criteria: the column is the position in the direction of travel of the gantry crane 6b, the row is the position in the traverse direction perpendicular to the direction of travel, and the tier is the position in the vertical direction.
[0022] In assignment step S2, multiple cargo handling operation data are assigned to each cargo handling equipment 6. For example, cargo handling operation data for work item name 1 is assigned to a gantry crane 6b that performs cargo handling operations on 3 lanes, and cargo handling operation data for work item name 2 is assigned to a gantry crane 6b that performs cargo handling operations on 5 lanes. Similarly, if the cargo handling equipment 6 consists of in-plant chassis 6c, multiple cargo handling operation data are assigned to each in-plant chassis 6c.
[0023] In creation step S3, a work schedule is created for each piece of cargo handling equipment 6. The management system 10 performs data processing to create a work schedule for each piece of cargo handling equipment 6, which combines multiple cargo handling work times and idle time in between work times, provided that the cargo handling efficiency from start to finish, as indicated by numerous pieces of cargo handling work data, does not fall below a certain standard, while satisfying the constraint that the total cargo handling efficiency from start to finish does not fall below a certain standard. The method for creating the work schedule in creation step S3 may use an existing method. However, this differs from conventional methods in that it creates a work schedule that combines not only cargo handling work times but also idle time.
[0024] The criteria for cargo handling efficiency can be set arbitrarily. This criterion only needs to eliminate work schedules that clearly reduce cargo handling efficiency. Constraints may be set to maximize the number of packages that can be processed at Terminal 1, to avoid delaying the completion times of numerous cargo handling operations, or to minimize the impact on reducing cargo handling efficiency. These are conditions that the solution must satisfy in a mathematical programming problem (optimization problem), and they limit the calculations performed by the management system 10.
[0025] Cargo handling efficiency can be evaluated by the number of container loads (such as 2-liter containers) that can be handled per unit of time, or by the amount of fuel consumed per unit of time.
[0026] Work schedules can be created using machine learning predictive models or mathematical optimization. A work schedule may be created by predicting fuel consumption for a large number of cargo handling operations, and then using a predictive model generated by machine learning from the scheduled execution times of numerous cargo handling operations and the predicted fuel consumption, setting multiple cargo handling operations and gaps. Alternatively, a work schedule may be created by setting multiple cargo handling operations and gaps using a predictive model generated by machine learning that uses a large number of accumulated work schedules as training data, along with a large number of cargo handling operations. Alternatively, a work schedule may be created by setting multiple cargo handling operations and gaps using a large number of cargo handling operations and an optimization algorithm. The training data consists of a large number of accumulated work schedules. Machine learning is only required if it is conditional. Since it is also an optimization problem, methods such as gradient descent, genetic algorithms, and Bayesian optimization may be used instead of predictive models.
[0027] In the setting step S4, at least one of several gaps set in the work schedule is selected, and a supply operation is set to supply hydrogen gas from the supply equipment 11 to the cargo handling equipment 6 during this gap. The creation step S3 and the setting step S4 may be executed simultaneously, and the supply operation may be set at the same time as the cargo handling work time and gaps are set.
[0028] In notification step S5, the created work schedule is notified to each cargo handling equipment 6 and supply equipment 11. As illustrated in Figure 2, the management system 10 may be equipped with a communication device 17, and the work schedule may be notified to the cargo handling equipment 6 and supply equipment 11 via this communication device 17. The cargo handling equipment 6 and supply equipment 11 have devices such as communication devices for receiving the work schedule from the management system 10.
[0029] As illustrated in Figure 5, the work schedule created by the management system 10 includes not only loading and unloading time but also gap time. This work schedule is for a gantry crane 6b that performs loading and unloading operations on two lanes. In the embodiment illustrated in Figure 5, one of the gap time slots is set to supply operation R1. The loading and unloading data corresponding to supply operation R1 may specify the position where the supply operation is performed, for example, five rows.
[0030] If the gantry crane 6b is a manned crane, the work schedule is displayed on the monitor of the gantry crane 6b. The operator performs the cargo handling operations while checking the work schedule. For example, the cargo handling operations are performed sequentially from top to bottom of the work schedule.
[0031] The work schedule, which satisfies the constraint that cargo handling efficiency does not fall below a certain standard, incorporates gaps in time when cargo handling operations are not performed. These gaps can be used to supply hydrogen gas to the cargo handling equipment 6. Instead of replenishing fuel that has run low during cargo handling operations as indicated by numerous cargo handling data, it is possible to replenish the fuel to be consumed in the next cargo handling operation using the gaps in time between multiple cargo handling operations. Furthermore, since the timing of the supply operation is predetermined, preparations for the supply operation can be made in advance. This is advantageous in suppressing the decrease in cargo handling efficiency caused by fuel replenishment.
[0032] A series of consecutive operations are involved in the cargo handling operations of the gantry crane 6b. As illustrated in Figure 1, multiple containers 2 may be transported in succession from a container ship 4 to a designated storage lane 3, or from a designated storage lane 3 to a container ship 4. Cargo handling operations performed between such a container ship 4 and terminal 1 are hereinafter referred to as on-board cargo handling. The shorter the mooring time of the container ship 4, the greater the amount of cargo that can be processed at terminal 1, thereby improving cargo handling efficiency. Therefore, it is desirable that on-board cargo handling be performed in a short amount of time and in a concentrated manner.
[0033] To efficiently handle cargo on board, multiple containers 2 stored in storage lane 3 may be rearranged. This may involve changing the position of containers 2 within a single storage lane 3, or moving containers 2 from one storage lane 3 to another. This type of cargo handling performed in storage lanes 3 is sometimes referred to as rearrangement.
[0034] Containers 2 may be brought into storage lane 3 from outside Terminal 1 by an external chassis 8, or containers 2 in storage lane 3 may be brought out of Terminal 1 by an external chassis 8. This type of cargo handling between storage lane 3 and external chassis 8 may hereafter be referred to as external cargo handling.
[0035] A series of consecutive cargo handling operations, such as onboard cargo handling, sorting cargo handling, and onboard cargo handling, may be grouped together and configured as a data group. In Figure 5, each data group is assigned a different alphabet to the name of the work item. For example, A1-3 is onboard cargo handling, B1-5 is sorting cargo handling, and C1-4 is onboard cargo handling.
[0036] A data group is formed by grouping together adjacent data when multiple cargo handling operation data assigned to the target cargo handling equipment 6 are arranged chronologically. Data groups are set in creation step S3 based on the cargo handling operation data. For example, if there is a series of cargo handling operation data where the column for the gantry crane 6b is almost the same, the management system 10 will group these cargo handling operation data into the same data group. Data groups may also be set in assignment step S2, for example, when assigning a large number of cargo handling operation data to each cargo handling equipment 6.
[0037] The data group may be set, for example, in the loading step S1. For example, when multiple cargo handling operation data are set as vessel cargo handling, they are pre-linked as the same data group.
[0038] The display method and included information of cargo handling operation data and data groups illustrated in Figure 5 are examples only, and the present invention is not limited thereto. The display method of cargo handling operation data, etc. can be changed as appropriate, and the information included in cargo handling operation data, etc. can be added as appropriate.
[0039] As illustrated in Figure 6, the management system 10 may have an estimation step S6 that estimates the required amount P1, which is the amount of hydrogen gas required by the cargo handling equipment 6 for a cargo handling operation, based on the cargo handling operation data of the work schedule. In estimation step S6, the required amount P1 [kg], which is the amount of hydrogen gas consumed in that cargo handling operation, is estimated for each cargo handling operation data of the work schedule created in creation step S3. The required amount P1 is estimated, for example, as the weight of hydrogen gas. In estimation step S6, the required amount P1 can be estimated, for example, from the workload of the cargo handling equipment 6. Estimation step S6 is not a mandatory component.
[0040] As illustrated in Figure 7, a gantry crane 6b stopped in a row unloads a 3-row, 2-tier container 2 onto a premises chassis 6c. In Figure 7, the movement path of the container 2 is shown with a dashed line for illustrative purposes. Once the position of the container 2 to be handled is determined, the workload of the gantry crane 6b can be determined from the height to which the container 2 is lifted and the distance it moves in the row direction (left-right direction in Figure 7). From this workload, the required amount P1 is estimated in estimation step S6. Similarly, when the gantry crane 6b travels in the row direction (front-back direction in Figure 7), the workload is determined from the weight of the gantry crane 6b and the distance traveled, and from this workload, the required amount P1 is estimated in estimation step S6. The greater the distance over which the container 2 and the gantry crane 6b are moved, the greater the workload and the greater the hydrogen gas consumption.
[0041] The estimation step S6 may have a configuration that determines the amount of work considering the weight of the container 2 to be handled, and then estimates the required amount P1 from this amount of work. In conventional management systems, the weight of each container 2, including its contents, is sometimes recorded for each container number. The management system 10 can obtain the weight of container 2 from, for example, the handling data. For example, there will be a difference in the required amount P1 between an empty 4-ton container and a 25-ton container that is nearly filled to the limit. This is advantageous for improving the accuracy of the estimation of the required amount P1 in estimation step S6. If weight is not considered in estimation step S6, the weight of container 2 may be predetermined, for example, 15 tons, and estimation step S6 may determine the amount of work based on this predetermined weight.
[0042] As illustrated in Figure 2, the cargo handling equipment 6 has a remaining amount sensor 18 that measures the remaining amount P2 of hydrogen gas in the hydrogen tank on which it is mounted. The management system 10 can obtain the remaining amount P2 from this remaining amount sensor 18 via the communication device 17. The management system 10 may have a configuration that allows it to obtain the remaining amount P2 in estimation step S6. The remaining amount sensor 18 may consist of, for example, a pressure sensor that measures the pressure inside the hydrogen tank, or a weight sensor that measures the weight of the hydrogen tank and the hydrogen gas inside.
[0043] The estimation step S6 may have a configuration that estimates the required time P3 [min] for each cargo handling operation data. In estimation step S6, the travel distance of the gantry crane 6b and the travel distance of the container 2 are determined from the contents of the cargo handling operation data, and the required time P3 for that operation is estimated. Next, based on the assumption that hydrogen gas is consumed in proportion to the required time P3, the required amount P1 may be estimated in estimation step S6.
[0044] In the embodiment illustrated in Figure 6, the management system 10 sets the supply operation R in the work schedule based on the values of the required amount P1 and the remaining amount P2 in the setting step S4. In this embodiment, the management system 10 sets the cargo handling work time and the idle time in the creation step S3, and then sets the supply operation in the setting step S4.
[0045] As illustrated in Figure 8, in estimation step S6, the required amount P1 of hydrogen gas is estimated for each cargo handling operation data. By accumulating this required amount P1, the amount of hydrogen gas needed up to a predetermined cargo handling operation data can be estimated. If the remaining amount P2 acquired by the management system 10 from the remaining amount sensor 18 of the gantry crane 6b is, for example, 3.2 kg, then when the work item name is C2, the accumulated required amount P1 becomes 3.45 kg, exceeding the remaining amount P2. In setting step S4, a supply operation R is inserted into a gap time set at a time t before the required amount P1 exceeds the remaining amount P2, that is, before C2. For example, a supply operation R is set into a gap time between work item names A3 and B1, or between B2 and B3, or between B5 and C1. Multiple supply operations R may be set into separate gap times. A supply operation R may be set into any gap time in the work schedule as long as the accumulated value of the required amount P1 does not exceed the remaining amount P2.
[0046] The table illustrated in Figure 8 is not managed as a work schedule. However, it may be changed to display the required quantity P1 and required time P3 in the work schedule as needed. In the setting step S4, the work schedule into which the supply work R has been inserted is sent from the management system 10 to each material handling device 6 and each supply device 11 in the notification step S5.
[0047] The management system 10 can set supply operations R during gaps in the work schedule. Supply operations R can be set in advance as one of the work items for the cargo handling equipment 6. Since a schedule can be set to refuel before the cargo handling equipment 6 runs out of fuel, it can be said that supply operations R are controlled by feedforward. This is advantageous in suppressing a decrease in cargo handling efficiency because it prevents situations where the cargo handling equipment 6 runs out of fuel and becomes inoperable.
[0048] If the supply equipment 11 is mobile, the supply equipment 11a can be moved or prepared for the supply operation R while the cargo handling equipment 6 is performing cargo handling operations. Also, if there is a shortage of fuel stored at terminal 1, orders for fuel from outside terminal 1 can be placed in advance. This is advantageous in suppressing a decrease in cargo handling efficiency.
[0049] As illustrated in Figure 8, the setting step S4 may have a configuration that obtains the required time P3 from the estimation step S6 and sets the start time t of the supply operation R from this required time P3 and the current time. For example, if the name of the work item currently being performed is B3, the current time is 10:14, and the cumulative required time P3 until the supply operation R2 is 6 minutes, the setting step S4 sets the start time t of the supply operation R2 to 10:20.
[0050] Setting step S4 allows a time t to be assigned to the work schedule. Since the start time t of the supply operation R is set, for example, the mobile supply equipment 11a can be moved in advance and made available for standby at the location where the gantry crane 6b receives the fuel supply. If the mobile supply equipment 11a is operated by an operator, the system may be configured to notify the supply equipment 11a of the start time t from the management system 10. The mobile supply equipment 11a has equipment such as a communication device for receiving notifications sent from the management system 10.
[0051] The setup step S4 may have a configuration that assigns a start time t to each cargo handling operation data in addition to the start time t of the supply operation R. There may be a predetermined time t at which cargo handling operations can begin after the container ship 4 has docked at the quay 5. The setup step S4 may have a configuration that sets the start time t of predetermined cargo handling operation data based on this time t. As illustrated in Figure 8, if data group C is onboard cargo handling and the time t at which cargo handling with the container ship 4 can begin is 11:00, then it is clear that the operation of C1 will start at least after 11:00. The start time t of C1 is set to 11:00, for example.
[0052] The system may have a configuration in which, each time an item of the cargo handling data is executed and processed, the start time t of the supply operation R and each cargo handling data is corrected in the setting step S4. In this case, the setting step S4 and the estimation step S6 are executed repeatedly. Even if the time required for the operation differs from the estimated required time P3, or if there is a delay in the operation, it becomes easier to maintain the accuracy of the start time t. As the items of the cargo handling data are executed and, for example, the item of supply operation R2 approaches, the accuracy of the start time t for supply operation R2 can be improved.
[0053] In the setup step S4, the configuration may include inserting supply work R during the gaps between data groups. In this case, supply work R is inserted during the gaps between work item names A3 and B1, and between B5 and C1, as shown in Figure 8. No supply work R is inserted during the gap between B2 and B3.
[0054] When a series of cargo handling operations must be performed in a short period of time, such as onboard cargo handling, supply operations R are not performed in between, which is advantageous for improving cargo handling efficiency. Even if a problem occurs during supply operations R and the work cannot be completed on time, the impact on the cargo handling operations can be minimized because it is not performed in the middle of a series of cargo handling operations.
[0055] As illustrated in Figure 6, the management system 10 may have a configuration that performs a calculation step S7 to calculate the supply amount P4 [kg], which is the amount of hydrogen gas to be supplied in the supply operation R. The calculation step S7 is not a mandatory configuration requirement. The calculation step S7 may have a configuration in which a lower limit is set when the supply amount P4 is calculated. In this case, the calculation step S7 obtains the required amount P1 from the estimation step S6 until the end of the data group after the supply operation R. The calculation step S7 calculates the supply amount P4 using the amount of hydrogen gas that is the difference between this required amount P1 and the remaining amount P2 as the lower limit. The calculated supply amount P4 is linked to the work schedule as data. The supply equipment 11 may be configured to receive information on the supply amount P4 along with the start time t of the supply operation R when it receives notification from the management system 10 regarding the supply operation R.
[0056] A specific example is explained below. When supply operation R2 is performed between work items B5 and C1 as illustrated in Figure 8, calculation step S7 obtains the required amount P1 until the end of data group C from estimation step S6. When work item B3 is completed, calculation step S7 obtains the current remaining amount P2 and the required amount P1 for B4-5 (0.7 kg) and C1-16 (8.0 kg). If the current remaining amount P2 is, for example, 2.0 kg and the required amount P1 is 0.7 + 8.0 = 8.7 kg, the difference of 6.7 kg is calculated in calculation step S7 as the lower limit of the supply amount P4. In supply operation R2, 6.7 kg or more of fuel is supplied to the cargo handling equipment 6.
[0057] In calculation step S7, the supply quantity P4 is set, for example, to the lower limit of 6.7 kg. The supply quantity P4 may also be set by adding a predetermined amount, such as 1.0 kg, to the lower limit. In this case, the supply quantity P4 would be 6.7 + 1.0 = 7.7 kg. The supply quantity P4 may also be set by multiplying the lower limit by a predetermined multiplier, such as 120%. In this case, the supply quantity P4 would be 6.7 * 1.20 = 8.04 kg.
[0058] The configuration in which a lower limit is set in calculation step S7 prevents the cargo handling equipment 6 from running out of fuel and becoming inoperable during the operation of data group C, which follows the supply operation R2. This is advantageous in suppressing a decrease in cargo handling efficiency.
[0059] The calculation step S7 may have a configuration in which an upper limit is set when the supply amount P4 is calculated. In this case, the calculation step S7 obtains the start time t of the data group after the supply operation R from the work schedule. The supply amount P4 is calculated in the calculation step S7 with the amount of hydrogen gas that can be supplied to the cargo handling equipment 6 by this start time t as the upper limit. The calculated supply amount P4 is linked to the work schedule as data.
[0060] A specific example is explained below. When supply operation R2 is performed between work items B5 and C1 as illustrated in Figure 8, calculation step S7 obtains a start time t, such as 11:00, from the work schedule in data group C. If supply operation R2 is completed by this start time t, 11:00, the cargo handling operations in data group C will start without delay. If the start time t for supply operation R2 is set to 10:20 in the work schedule, for example, supply operation R2 can be performed for 40 minutes.
[0061] In creation step S3, when setting gaps in time between multiple cargo handling operations where cargo handling operations are not performed, the same method as in calculation step S7 above may be used. In other words, if there are cargo handling operations with a pre-set start time t, gaps can be set at the time before that start time.
[0062] Supply operation R includes tasks such as connecting the supply equipment 11 and the cargo handling equipment 6 with piping for hydrogen gas. The time during which hydrogen gas can be supplied is shorter than the time of supply operation R1, for example, 35 minutes. The amount of hydrogen gas that can be supplied in this time, for example 59.5 kg, becomes the upper limit of the supply amount P4. In supply operation R2, 59.5 kg or less of fuel is supplied to the cargo handling equipment 6.
[0063] In calculation step S7, the supply quantity P4 is set, for example, to the upper limit of 59.5 kg. The supply quantity P4 may also be set by subtracting a predetermined amount, such as 5.0 kg, from the upper limit. In this case, the supply quantity P4 would be 59.5 - 5.0 = 54.5 kg. The supply quantity P4 may also be set by multiplying the upper limit by a predetermined multiplier, such as 90%. In this case, the supply quantity P4 would be 59.5 * 0.9 = 53.55 kg.
[0064] If the start time t of the data group after supply operation R2 is not set, the upper limit of the supply amount P4 may be set to the amount that fills the hydrogen tank of the cargo handling equipment 6. If the capacity of the hydrogen tank of the gantry crane 6b is, for example, 100 kg, it takes, for example, about 1 hour to fill it from a state where the remaining amount P2 is almost zero.
[0065] The configuration, which sets an upper limit in calculation step S7, allows fuel to be supplied to the cargo handling equipment 6 in time for the start time t of data group C, which follows the supply operation R2. This is advantageous in suppressing a decrease in cargo handling efficiency.
[0066] If the supply device 11 performs supply operations R to multiple cargo handling devices 6, the supply amount P4 may be calculated in calculation step S7 using the amount of hydrogen gas that the supply device 11 can supply in time for the next supply operation R as the upper limit. This is advantageous for improving the operating rate of the supply device 11.
[0067] The calculation step S7 may include a configuration that calculates the maximum amount of hydrogen gas that can be supplied to the cargo handling equipment 6 based on the difference between the pressure in the hydrogen tank mounted on the cargo handling equipment 6 and the pressure mounted on the supply equipment 11. In this case, the calculation step S7 calculates the maximum amount of hydrogen gas calculated based on the differential pressure and the maximum amount of hydrogen gas that can be supplied from the supply equipment 11 to the cargo handling equipment 6 during the set gap time for the supply operation R. The maximum amount of hydrogen gas based on the differential pressure and the maximum amount of hydrogen gas based on the gap time are compared, and the smaller one is set as the upper limit in the calculation step S7.
[0068] This configuration avoids the problem where, when filling the cargo handling equipment 6 with hydrogen gas using differential pressure, the set supply amount P4, which is determined by utilizing the gap time, cannot actually be supplied to the cargo handling equipment 6. When calculating the supply amount P4 in calculation step S7, the configuration that utilizes differential pressure is not a mandatory requirement. For example, if the supply equipment 11 has a compressor and hydrogen gas is supplied to the cargo handling equipment 6 under pressure, the set supply amount P4 can be supplied to the cargo handling equipment 6 using only the gap time.
[0069] In calculation step S7, both a lower limit and an upper limit may be set, and the supply amount P4 may be calculated based on these. In this case, the supply amount P4 may be set to the amount shown in the example of the upper limit. According to the above example, the supply amount P4 is set to 59.5 kg. The supply amount P4 may also be set to the amount that is the average of the upper limit and the lower limit. According to the above example, the supply amount P4 is set to (6.7 + 59.5) / 2 = 33.1 kg. Setting the supply amount P4 to the amount that is the average of the upper limit and the lower limit rather than the upper limit shortens the supply operation R time, so the supply equipment 11a can perform the supply operation R of the other gantry crane 6b.
[0070] For example, the lower limit may exceed the upper limit if the amount of hydrogen gas required to execute the next data group C after supply operation R2 is insufficient, such as when the time available for supply operation R2 is short. This makes it difficult to proceed with the work schedule. In such cases, the management system 10 may have a configuration to send a notification requesting a significant change to the work schedule. Workers in the management building 7 may take measures such as changing the storage lane 3 where container 2 is stored and using different cargo handling equipment 6 for handling. This change in storage lane 3 may also be achieved by repeating the assignment step S2.
[0071] On the other hand, by setting a broad range for creating the work schedule, such as up to 24 hours in advance, it becomes easier to avoid the lower limit exceeding the upper limit.
[0072] As illustrated in Figure 6, the estimation step S6 may include a configuration that estimates the required time P3 for the supply operation R based on the supply quantity P4 calculated in the calculation step S7. In this case, the setting step S4 may include a configuration that sets the end time t of the supply operation R from the aforementioned required time P3 and the current time.
[0073] Since the end time t of the supply operation R is set, it becomes possible to set the work schedule for the next supply operation R for other supply equipment 11. Because the start time t and end time t of the supply operation R for multiple material handling equipment 6 can be set in advance, it is advantageous for improving the utilization rate of the supply equipment 11.
[0074] Specifically, the supply operation R for the second cargo handling device 6 can be scheduled for a time after the end time t of the supply operation R for the first cargo handling device 6. The number of supply devices 11 is not limited to one. Terminal 1 may have multiple supply devices 11. In the work schedule for each cargo handling device 6, it is desirable that the number of overlapping gaps at the same time be based on the number of supply devices 11. This avoids the problem where supply operations R are scheduled for the gaps of multiple cargo handling devices 6, but the supply operations cannot be performed according to the work schedule because there are not enough supply devices 11.
[0075] Examples of work schedules set for multiple cargo handling devices 6 are shown in Figures 9 and 10. If the gantry crane 6b is a manned crane operated by an operator, the operator performs cargo handling operations while checking this work schedule. As illustrated in Figures 9 and 10, the work schedule includes the start and end times of the supply operation R, as well as a column indicating the position where the supply operation R is performed. To avoid the gantry crane 6b moving in conjunction with the supply operation R, it is desirable that the column be set, for example, to the position where the previous work item was completed.
[0076] Priorities for supply operations R are set for multiple cargo handling devices 6. The priority can be set such that, for example, cargo handling devices 6 that perform on-board cargo handling have a higher priority, followed by on-board cargo handling, and then sorting cargo handling, with priority decreasing in that order. The management system 10 sets the supply operations R starting with the cargo handling devices 6 with the highest priority. If the supply devices 11 are mobile, an indicator to improve the efficiency of the movement route of the supply devices 11a may also influence the aforementioned priority. This makes it possible to achieve a situation where the movement route of the supply devices 11a is the shortest possible while prioritizing the supply operations R for the cargo handling devices 6 with the highest priority.
[0077] As illustrated in Figure 11, the mobile supply equipment 11a may have a vehicle 20 and hydrogen tanks 21 mounted on the vehicle 20. In this embodiment, the supply equipment 11a consists of two vehicles 20. The first vehicle 20 has a plurality of hydrogen tanks 21 arranged inside a 20ft container. These hydrogen tanks 21 are filled with hydrogen gas compressed to a high pressure, such as 82 MPa. The vehicle 20 is equipped with 16 hydrogen tanks 21, each filled with, for example, 12.5 kg of hydrogen gas.
[0078] The second vehicle 20 has a precooler 22 for cooling the hydrogen gas supplied from the hydrogen tank 21, a dispenser 23 for supplying the hydrogen gas cooled by the precooler 22 to the cargo handling equipment 6, and a battery 24 for supplying electricity to the precooler 22 and the dispenser 23. The precooler 22 and the other components may be placed inside a 20ft container mounted on the vehicle 20. In Figure 11, for illustrative purposes, the piping for transporting hydrogen gas is shown with thick lines, and the power cable connected to the battery 24 is shown with dashed lines.
[0079] In accordance with the information sent from the management system 10, the supply equipment 11a, consisting of two vehicles 20, moves to the vicinity of the gantry crane 6b before the start time t of the supply operation R. The two vehicles 20 may consist of manned vehicles operated by workers or unmanned vehicles operated by automatic control.
[0080] Figure 12 shows an example of a work schedule notified to the supply equipment 11a. If the vehicle 20 is a manned vehicle driven by a worker, the worker performs the supply work R while checking this work schedule. The work schedule includes the number of the cargo handling equipment to be supplied, the start time and end time for each supply work R, and the location and supply amount P4 for the supply work R. The management system 10 will notify the supply equipment 11a to move to the location where the supply work will be performed before the start time of the supply work R. The location where the supply work R will be performed is set as the storage lane number and its column. The supply equipment 11a moves to the specified location by the start time of the supply work R.
[0081] As illustrated in Figure 11, when starting the supply operation R, the worker connects the hydrogen tank 21 and the precooler 22 with piping, and connects the dispenser 23 and the handling equipment 6 with piping. Hydrogen gas is filled from the hydrogen tank 21 to the handling equipment 6 by differential pressure. When ending the supply operation R, the worker disconnects the piping connected to the precooler 22 and the handling equipment 6.
[0082] Since the mobile supply equipment vehicle 20 of the mobile supply equipment 11a is easier to move than the gantry crane 6b, the vehicle 20 can move to the vicinity of the gantry crane 6b to perform the supply operation R. The supply operation R can be performed in the middle of the extension direction of the storage lane 3. Since the vehicle 20 moves at a faster speed than the gantry crane 6b, it is advantageous for efficiently performing the supply operation R.
[0083] In this embodiment, since the supply device 11a supplies hydrogen gas to the cargo handling equipment 6 using differential pressure, a compressor is not required. Because a power supply for the compressor is not required, the supply operation R can be performed at any location. A compressor requires, for example, a 110kW power supply and needs to be connected to a 450V power cable. If the supply device 11a is equipped with a compressor, the supply operation can only be performed in locations where a 450V power cable is available. The precooler 22 and dispenser 23 can operate with a power supply of about 10kW and can be powered by a battery 24 mounted on the vehicle 20.
[0084] Since the supply equipment 11a consists of two vehicles 20, if the amount of hydrogen remaining in the hydrogen tank 21 becomes low, the supply operation R can be continued by arranging for another vehicle 20 equipped with the hydrogen tank 21. By preparing multiple vehicles 20 equipped with hydrogen tanks 21 for each vehicle 20 equipped with a dispenser 23, etc., the supply operation R can be carried out efficiently. This is advantageous for improving the operating rate of the supply equipment 11a.
[0085] The supply equipment 11a is not limited to two vehicles 20. It may consist of a single vehicle 20. A 40ft container may be mounted on this vehicle 20, and equipment such as a dispenser 23 and a hydrogen tank 21 may be placed inside this 40ft container.
[0086] As illustrated in Figure 1, Terminal 1 may have a supply lane 25 on which the vehicle 20 of the supply equipment 11a travels. The supply lane 25 is formed to the side of the storage lane 3. A cargo handling lane 26 is formed between the supply lane 25 and the storage lane 3 on which the in-house chassis 6c and the external chassis 8 travel. The vehicle 20 and the in-house chassis 6c, etc., will each travel in their own dedicated lane. The vehicle 20 performing the supply work R will not obstruct the movement of the in-house chassis 6c, etc. This is advantageous in suppressing a decrease in cargo handling efficiency. Alternatively, Terminal 1 may not have a supply lane 25, and the vehicle 20 constituting the supply equipment 11a may travel in the cargo handling lane 26 to approach the gantry crane 6b.
[0087] As illustrated in Figure 1, terminal 1 may have a work area 27 for performing supply operations R. The work area 27 is formed at the end of the storage lane 3 in the direction of extension (left-right direction in Figure 1). In this case, a work area 27 is formed for each storage lane 3. When performing supply operations R, the gantry crane 6b and the vehicle 20 of the supply equipment 11a move to the work area 27. Because the location where supply operations R are performed is limited, it becomes possible to prepare, for example, a 450V power cable. It becomes possible to configure the supply equipment 11a with a vehicle 20 equipped with a compressor.
[0088] The supply operation R is performed at the end of the storage lane 3. Even when multiple gantry cranes 6b perform cargo handling operations in a single storage lane 3, the gantry crane 6b performing the supply operation R does not interfere with the cargo handling operations of other gantry cranes 6b. Furthermore, the supply equipment 11a performing the supply operation R does not obstruct the movement of the in-plant chassis 6c, etc. This is advantageous in suppressing a decrease in cargo handling efficiency at Terminal 1.
[0089] As illustrated in Figure 13, even when the cargo handling equipment 6 is an in-plant chassis 6c, the work schedule is set by the management system 10 in the same way as with the gantry crane 6b. The container number of the container 2 to be handled, the receiving position for receiving the container 2, and the unloading position for unloading the container 2 are set. In estimation step S6, the required amount P1 is estimated from the travel distance of the in-plant chassis 6c. Estimation step S6 may also have a configuration that estimates the amount of work from the weight of the container 2 to be handled, in addition to the travel distance of the in-plant chassis 6c, and estimates the required amount P1 from this amount of work. In setting step S4, a supply operation R is set in at least one of several gaps in time. If the management system 10 has a configuration that performs estimation step S6, the supply operation R is set in the work schedule based on the remaining amount P2 in the hydrogen tank of the in-plant chassis 6c and the required amount P1. This supply operation R is set in a gap in time.
[0090] In accordance with the instructions for supply operation R in the work schedule, the on-site chassis 6c travels to the fixed supply equipment 11b to receive hydrogen gas. If the management system 10 is configured to perform calculation step S7, the on-site chassis 6c receives an amount of hydrogen gas corresponding to the supply amount P4 set in calculation step S7. A sensor for identifying the on-site chassis 6c may be placed near the dispenser of the supply equipment 11b. Hydrogen gas is supplied to the on-site chassis 6c based on the supply amount P4 corresponding to the identification number of the on-site chassis 6c. Alternatively, the identification number may be entered into the dispenser by an operator, and a preset supply amount P4 may be supplied to the on-site chassis 6c.
[0091] A work schedule may be set for the fixed supply device 11b. This work schedule may include, for example, the identification number of the on-site chassis 6c, the supply quantity P4, and the start and end times of the supply operation R. The fixed supply device 11b has a communication device, etc., for receiving the schedule and supply quantity P4 notified from the management system 10.
[0092] This is advantageous in avoiding the problem of in-plant chassis 6c running out of fuel during loading and unloading operations. Furthermore, the time and amount P4 supplied by each in-plant chassis 6c receiving the supply operation R from the supply equipment 11b can be adjusted according to the work schedule. This avoids situations where multiple in-plant chassis 6c are waiting for the supply operation R near the supply equipment 11b. This is advantageous in improving the operational efficiency of the in-plant chassis 6c.
[0093] If the external chassis 8 uses hydrogen gas as fuel, the external chassis 8 may be included in the cargo handling equipment 6. The external chassis 8 consists of a manned chassis or an unmanned chassis. It is desirable that the external chassis 8 has equipment similar to that of the in-house chassis 6c. Specifically, it is desirable that it has equipment such as a communication device for receiving work schedules sent from the management system 10 and transmitting the remaining amount P2 of the hydrogen tank on board to the management system 10. Similar to the in-house chassis 6c, the external chassis 8 can travel to the fixed supply equipment 11b to receive hydrogen gas supply in accordance with the instructions for supply work R in the work schedule.
[0094] Even if an external chassis 8 does not have the same equipment as an in-house chassis 6c, it may still be included in the cargo handling equipment 6. When the external chassis 8 is checked in at gate 9 of Terminal 1, the identification number of the external chassis 8 and the container number to be handled by the external chassis 8 are recorded in the management system 10. At this time, the remaining amount P2 of the external chassis 8's hydrogen tank may also be recorded in the management system 10. The external chassis 8 receives the work schedule and other information set by the management system 10 at gate 9. The external chassis 8 can receive hydrogen gas supply according to the instructions for supply work R in the work schedule. Even if the external chassis 8 does not have a communication device or other equipment to exchange data with the management system 10, the external chassis 8 can still receive the work schedule and other information at gate 9. Terminal 1 can incorporate the external chassis 8 into its control system as cargo handling equipment 6.
[0095] When the cargo handling equipment 6 and supply equipment 11 are controlled by an operator, the operator performs the work while referring to the work schedule. When the cargo handling equipment 6, etc. are automatically controlled by a control device, the control device controls the cargo handling equipment 6, etc. based on the work schedule.
[0096] The above describes the supply operation R for the cargo handling equipment 6 that uses hydrogen gas as fuel. The management system 10 of the present invention can also be used when supplying diesel fuel to cargo handling equipment or when the supply equipment charges the storage battery of the cargo handling equipment. Cargo handling equipment that uses diesel fuel can receive diesel fuel supply without reducing cargo handling efficiency, even if the fuel tank is made smaller.
[0097] When supply equipment charges cargo handling equipment, the number of charging cycles may increase, similar to when hydrogen gas is used as fuel. Even in such cases, the cargo handling equipment can be charged efficiently, thus suppressing the decrease in cargo handling efficiency.
[0098] The cargo handling equipment 6 may be equipped with a storage battery, such as a lithium-ion battery, and the supply equipment 11 may supply electricity as fuel. In this case, the cargo handling equipment 6 and the supply equipment 11 are equipped with storage batteries instead of hydrogen tanks. In this specification, the term "fuel" includes electricity.
[0099] When the fuel is electricity, the required amount P1, remaining amount P2, and supplied amount P4 are expressed in terms of the amount of electricity [kWh]. In estimation step S6, the required amount P1 [kWh], which is the amount of electricity consumed in a predetermined cargo handling operation, is estimated. The remaining amount sensor 18 measures the remaining amount of electricity P2 [kWh] in the battery installed in the cargo handling equipment 6. In calculation step S7, the supplied amount P4 [kWh], which is the amount of electricity supplied in the supply operation R, is calculated.
[0100] The fuel may consist of methylcyclohexane, which is produced by chemically reacting hydrogen and toluene. In this case, the cargo handling equipment 6 is equipped with, for example, a hydrogen engine or fuel cell that uses hydrogen as fuel. Methylcyclohexane is dehydrogenated via a catalyst in a temperature environment of approximately 300°C, separating it into hydrogen and toluene. In this embodiment, the cargo handling equipment 6 includes a hydrogen engine, a dehydrogenation unit for separating hydrogen from methylcyclohexane, a tank for storing methylcyclohexane, and a tank for recovering the separated toluene. The dehydrogenation unit uses heat discharged from the hydrogen engine, for example, at a temperature of 300°C or higher, to separate the hydrogen. During the supply operation R, the supply equipment 11 is configured to supply methylcyclohexane to the cargo handling equipment 6 and recover toluene. Since the waste heat from the hydrogen engine is used as the heat source when dehydrogenating methylcyclohexane, the hydrogen separated from methylcyclohexane can be efficiently used as power for the cargo handling equipment 6.
[0101] The management system 10 assumes, when creating a work schedule, that the cargo handling efficiency from the start to the end of cargo handling operations, as indicated by a large amount of cargo handling data, does not fall below a certain standard. However, the present invention also includes cases where the work schedule does not satisfy the aforementioned constraints. For example, work schedules used in existing terminals may be reused. In some terminals, workers create work schedules based on rules of thumb. In other terminals, there may be existing systems that create work schedules based on predetermined rules. The management system 10 may have a configuration in which it sets gaps between cargo handling operations for an original work schedule prepared in advance for each cargo handling device 6, and creates a new work schedule that combines cargo handling operations and gaps. In this case, the management system 10 receives the original work schedule prepared in advance and outputs a new work schedule that combines cargo handling operations and gaps.
[0102] The present invention is not limited to a configuration in which a supply operation R, in which fuel is supplied from the supply device 11 to the cargo handling device 6, is scheduled during at least one of several gaps in time. Instead of the supply operation R, maintenance work or at least one of the following, such as a change of drivers or a break for the cargo handling device 6, may be scheduled during the gap.
[0103] The management system 10 of the present invention can also be said to have the following features. The management system 10 is a management system 10 that assigns multiple cargo handling work data from a large number of cargo handling work data to each of multiple cargo handling equipment 6, and is characterized by performing data processing to create a work schedule for each of the multiple cargo handling equipment 6 that incorporates multiple cargo handling work times in which cargo handling work is performed as indicated by the assigned multiple cargo handling work data, and gaps in time between those multiple cargo handling work times when no cargo handling work is performed.
[0104] The management system 10 may be configured to acquire location information and remaining quantity P2 of the cargo handling equipment 6 at predetermined time intervals, or it may be configured to acquire location information, etc., in real time. For example, the management system 10 can acquire location information, etc., of the cargo handling equipment 6, etc., at time intervals set in advance within the range of 1 second to 60 seconds.
[0105] The management system 10 may have a configuration for acquiring the location information of the cargo handling equipment 6. Specifically, for example, a configuration can be adopted in which multiple cargo handling equipment 6 are equipped with antennas for the Global Navigation Satellite System (GNSS). The location information of the cargo handling equipment 6 is acquired by these GNSS antennas and sent to the management system 10. The configuration in which the management system 10 acquires the location information of the cargo handling equipment 6 is not limited to the above. The management system 10 may also acquire the location information by detecting the relative position between a transponder installed at terminal 1 and the cargo handling equipment 6. The management system 10 may also have a configuration for acquiring the location information of mobile supply equipment 11a, similar to the cargo handling equipment 6. Here, the location information of the cargo handling equipment 6 and supply equipment 11a may include not only the current location information acquired from the GNSS antennas, but also future location information estimated from the location of container 2 specified in the work schedule and the direction of travel of the cargo handling equipment 6.
[0106] By acquiring location information of the cargo handling equipment 6, the management system 10 can determine whether the cargo handling equipment 6 is moving according to the work schedule. If the cargo handling equipment 6 is not moving according to the work schedule, it becomes possible to take measures such as changing the work schedule. The management system 10 can also determine whether the gaps in the work schedule are occurring as scheduled. Since the management system 10 can monitor the status of multiple cargo handling equipment 6, it is advantageous in suppressing a decline in cargo handling efficiency.
[0107] The management system 10 is configured to acquire the remaining fuel amount P2 of the cargo handling equipment 6, and may be configured to set a supply operation R to supply fuel from the supply equipment 11 to the cargo handling equipment 6 during at least one of several gaps in the work schedule, based on the location information of the cargo handling equipment 6, the remaining fuel amount P2, and the gaps in the work schedule. The management system 10 can determine whether the cargo handling equipment 6 can complete its movement to the location of the fixed supply equipment 11 by the time the supply operation R is scheduled. The management system 10 can also determine whether the cargo handling equipment 6 and the supply equipment 11a can meet by the time the supply operation R is scheduled, based on the location information of the cargo handling equipment 6 and the mobile supply equipment 11a. Since the management system 10 can determine whether the supply operation R can be executed as scheduled, it is possible to change the work schedule as needed. Depending on the location information of the cargo handling equipment 6 and the remaining fuel amount P2, it becomes possible to supply fuel to the cargo handling equipment 6 at an appropriate time. At this time, the work set during the gaps is not limited to the supply operation R, but may also be maintenance work, etc.
[0108] The management system 10 may include a configuration for setting the location where supply work R will be performed when scheduling supply work R during downtime. Based on the location information and remaining quantity P2 of the cargo handling equipment 6, it is possible to appropriately set the location where supply work R will be performed. This is advantageous in suppressing a decrease in cargo handling efficiency. The work for which the location is set at this time is not limited to supply work R, but may also be maintenance work, etc.
[0109] The terminal 1 according to the present invention may have a configuration similar to the management system 10 described above. In this case, the terminal 1 is a terminal comprising a plurality of cargo handling devices 6, a supply device 11 that supplies fuel to the cargo handling devices 6, and a management system 10 that assigns a plurality of cargo handling work data from a plurality of cargo handling work data to each cargo handling device 6. The management system 10 is characterized by performing data processing to create a work schedule for each of the plurality of cargo handling devices 6 that incorporates a plurality of cargo handling work times in which cargo handling work is performed as indicated by the assigned plurality of cargo handling work data, and gaps in time between those plurality of cargo handling work times in which no cargo handling work is performed. The management system 10 of this terminal 1 may have a configuration for acquiring location information of the cargo handling devices 6. The management system 10 of terminal 1 may have a configuration for acquiring the remaining amount P2 of fuel in the cargo handling devices 6, and may have a configuration for setting a supply operation R in which fuel is supplied from the supply device 11 to the cargo handling devices 6 in at least one of the plurality of gaps based on the location information, the remaining amount P2, and the gaps. The management system 10 of terminal 1 may have a configuration for setting the location in which the supply operation R is performed when setting the supply operation R in the gaps.
[0110] The management method according to the present invention may have the same configuration as the management system 10 described above. In this case, the management method is a management method that assigns multiple cargo handling work data from a large number of cargo handling work data to each of multiple cargo handling equipment 6, and is characterized by performing data processing to create a work schedule for each of the multiple cargo handling equipment 6 that incorporates multiple cargo handling work times in which cargo handling work is performed as indicated by the assigned multiple cargo handling work data and gaps in time between those multiple cargo handling work times in which no cargo handling work is performed. The management method may include a configuration for acquiring location information of the cargo handling equipment 6. The management method may include a configuration for acquiring the remaining amount P2 of fuel in the cargo handling equipment 6, and may include a configuration for setting a supply operation R in which fuel is supplied from the supply equipment 11 to the cargo handling equipment 6 in at least one of the multiple gaps based on the location information, the remaining amount P2, and the gaps in time. The management method may include a configuration for setting the location in which the supply operation R is performed when setting the supply operation R in the gaps in time.
