Description

  The present invention relates to a container chassis operation management system capable of efficiently performing cargo handling work in a container terminal.

  In the container terminal, a container yard where a container for loading or unloading the container ship is in contact with a quay where the container ship is anchored. Cargo handling equipment such as container cranes is in operation. The chassis includes a local chassis that loads and unloads containers in a container yard, and an external chassis that transports containers between landers.

  FIG. 6 is a plan view showing an example of the container terminal 1. The container ship 2 is moored to the quay 3 and the container 5 is loaded and unloaded by the quay container crane 4. The quay 3 is arranged at the edge of the container yard 6, and the container 5 loaded and unloaded on the container ship 2 is stored in the container yard 6. An appropriate number of containers 5 are stacked in a matrix to form a container block 5a, and an appropriate number of container blocks 5a are arranged in a matrix in the container yard 6. A chassis 7 is used to move the container 5 in the container yard 6 or to transport it to and from the shipper. A yard crane 8 is used to load and unload the container 5 on the chassis 7. The yard crane 8 shown in FIG. 6 is a bridge crane, and loads and unloads the container 5 in a state where it straddles the container block 5a and the chassis 7 stopped to the side of the container block 5a. The yard crane 8 moves in the traveling direction along the container block 5a and moves in the perpendicular direction along the right-angle lane 6a between the container block 5a and the container block 5a in order to move to the adjacent container block 5a. And can be done.

  Out of the chassis 7, the foreign chassis 7 enters the container yard 6 through the entrance gate Gi and leaves the exit gate Go or the subgate Gs. This is because the chassis 7 loaded with the actual container 5 containing the imported cargo needs to be bonded at the exit gate Go, and the chassis 7 loaded with the empty container 5 or the container 5 loaded. The chassis 7 that is not is not required to carry out bonded procedures, and is thus retired from the sub-gate Gs. On the side of the entrance gate Gi, there are a management building 9, a guardman stuffing station 10, an office building 11 and the like. In addition, an empty van pool 12, a repair shop 13, and a water washing place 14 in which empty containers 5 are stored are arranged on the opposite side of the management building 9 across the entrance gate Gi.

  In this type of container terminal 1, a chassis 7 and a yard crane 8 are operated under certain management. For example, if a reservation is made by a land carrier to make a visit to pick up a container 5 stored for land transportation, the corresponding container 7 is transferred to a position where the chassis 7 on the premises is easy to carry out. And wait for the land carrier to come. At this time, the yard crane 8 is used for loading / unloading the container 5 to / from the chassis 7. If the land carrier arrives at the entrance gate Gi, move the chassis 7 to the designated storage position after carrying out the prescribed procedures such as receiving a check on the document that contains information on the cargo to be picked up at the entrance gate Gi. Thus, the predetermined crane 5 is loaded or unloaded by the yard crane 8.

  Conventionally, the instruction regarding the work for loading and unloading the container 5 of the chassis 7 has been made by handing the oral or work plan document to the driver of the chassis 7 at the entrance gate Gi. For documents and verbal instructions, the chassis driver must carry various necessary documents and carry out the prescribed procedures at the gate Gi. In the gate Gi, the driver can check documents and documents This is a complicated operation, such as inputting the items described in 1 to the terminal device.

  Therefore, in order to improve the container transfer efficiency by eliminating the container loading / unloading procedure using documents at the gate Gi of the container terminal, Patent Document 1 sets a wireless IC card into which container logistics information is input. A trailer side terminal provided in a tractor head that receives and transmits logistics information, and a container terminal gate that processes the logistics information received from the trailer side terminal and transmits container storage information to the trailer side terminal and the yard crane side terminal. Disclosed is a container loading / unloading management device in a container terminal comprising a gate terminal provided and a yard crane terminal provided in a yard crane of a container yard that receives and transmits container storage information between the gate terminal and the terminal. Has been.

  Similarly, Patent Document 2 discloses a wireless IC card to which container logistics information is input, a trailer side terminal provided on a tractor head that sets the wireless IC card and receives / transmits logistics information, and the trailer side terminal. A terminal on a container terminal gate that mediates transfer of distribution information between the computer of the distribution information center and the trailer side via the gate side terminal processing the distribution information transmitted from the gate side terminal A container unloading / entry management apparatus in a container terminal comprising a computer of a distribution information center that transmits storage information such as a destination address of a trailer to a terminal is disclosed.

  Furthermore, Patent Document 3 discloses a container terminal in a container terminal having a main container yard and a temporary container yard. This is a carry-in management method, in which a wireless IC document tag that transmits a container number is set on the in-vehicle device, and a check gate having an antenna connected to a computer is provided at the entrance / exit of the temporary container yard. When the container is loaded in advance, make a reservation for the container outside the fixed time in advance to the computer, and when the tractor head pulls the chassis carrying the container and arrives at the entrance / exit of the temporary container yard, Of the container to be carried in from the wireless IC document tag set in When the antenna number is transmitted and the antenna receives the container number, it communicates with the computer and displays the destination address of the temporary container yard on the vehicle-mounted device, and the tractor head passes the designated delivery of the temporary container yard according to the instructions from the antenna. Move to the location, and when the tractor head delivers the container to the yard crane at that location and returns to the entrance / exit, it will send out to the antenna from the wireless IC document tag and register that the loading of the container is completed and exit.

  However, in the container carry-in / out management device described in Patent Documents 1 and 2, the trailer driver can move to a designated container delivery place and perform a predetermined work, but the procedure to be performed on the trailer The trailer and the yard crane will be instructed each time, and it is difficult to pre-set the cargo handling work schedule for loading and unloading containers at the container terminal, and the work efficiency can be improved as desired. Can not. Further, in the container carry-in management method described in Patent Document 3, the container carry-in system can be performed in 24 hours by performing work according to a predetermined schedule. It is difficult to respond quickly.

  Therefore, the container chassis operation management system according to the present invention is capable of responding promptly even when an unexpected situation such as a sudden change of work or a schedule occurs even if the operation is performed according to a predetermined schedule. The purpose is to be able to operate the container terminal smoothly.

  As a technical means for achieving the above object, a container chassis operation management system according to the present invention includes a chassis for container loading and unloading using a cargo handling device on a chassis for transporting containers. In a container chassis operation management system that adjusts operations in relation to cargo handling equipment, the container chassis management server includes cargo handling equipment management data, chassis management data, cargo handling work management data, and work procedure setting program. A chassis terminal device that exchanges information with the container yard management server and an ID tag that records the contents of the cargo handling work required by the chassis are mounted on the premises chassis, and the cargo handling equipment includes the The cargo handling equipment terminal device for exchanging information with the container yard management server and the chassis are provided. A tag reader that reads information recorded in the ID tag, reads information recorded in the ID tag provided in the chassis at an appropriate position in the container yard, and notifies the container yard management server of the read information The container yard management server receives a notification of chassis information obtained from the chassis ID tag, updates the chassis management data, and receives a notification of completion of a cargo handling operation by the cargo handling equipment. Updating the cargo handling equipment management data and the cargo handling work management data, updating the cargo handling work management data with the cargo handling equipment management data and the chassis management data, and the standby work content and work order at that time by the work procedure setting program, The optimum work is set in consideration of other necessary conditions, and the chassis terminal device and the cargo handling equipment terminal device are set. A list of the contents of the standby work is displayed at the same time, and the contents of the optimum work commanded to the chassis in charge of the cargo handling work and the cargo handling equipment are displayed in a specialized manner.

  For example, what is reserved for the day's work is recorded as standby work in the cargo handling work management data, and this data is sent to the cargo handling equipment terminal device of the cargo handling equipment and connected to the terminal device. A list is displayed on the display device. As a result, the operator of the cargo handling equipment and the driver of the chassis can grasp the current cargo handling work. In addition, the work to be commanded to the cargo handling equipment is specialized and displayed by, for example, blinking on a display device or by displaying it with a different color. Thereby, the operator can grasp the cargo handling work that he / she is in charge of, and moves the cargo handling equipment to the storage position of the container to be worked to perform a predetermined work. On the other hand, the chassis terminal device of the chassis is commanded with the chassis work specialized, and the driver moves the chassis to a storage position for loading or unloading the container according to the command.

  When the cargo handling work on the cargo handling equipment is completed, the operator notifies the container yard management server of the completion of the work. The container yard management server updates cargo handling equipment management data and cargo handling work management data based on this notification. In this case, the cargo handling device management data records that the cargo handling device is in a work waiting state, and the cargo handling work management data records that the cargo handling operation is completed. Next, the next cargo handling work is displayed in a specialized manner on the cargo handling equipment terminal device of the cargo handling equipment waiting for the work. As a result, the cargo handling device moves to the designated storage position and performs the cargo handling operation.

  The completed work is recorded as a completed work in the cargo handling work management data, and a log is saved.

  Further, the container chassis operation management system according to the invention of claim 2 rents an ID tag associated with a container related to cargo handling work when the foreign chassis passes through the gate, and the gate of the container terminal A gate terminal device for exchanging information with a container yard management server and a tag reader for reading information recorded in an ID tag provided in the chassis are provided.

  In the case of a foreign chassis, when a cargo handling reservation is made at a container terminal, an ID tag that records reservation contents can be prepared in advance, and this ID tag is lent when it comes to the building and held at an appropriate position on the chassis. The ID tag is returned when the foreign chassis leaves. At the gate, information on the work content of the chassis is read from the ID tag provided in the chassis by the tag reader, and sent to the container yard management server. In the container yard management server, information related to the foreign chassis is recorded in the chassis management data, and is recorded as standby work in the cargo handling work management data. Then, based on the cargo handling equipment management data and the cargo handling work management data related to the standby work, the work procedure setting program is executed to determine the order of the cargo handling work at that time. Based on this order, the work list is updated and the display is updated on the terminal device of the cargo handling equipment.

  For example, priority is given to the order in which the foreign chassis arrives among the standby operations, and the next cargo handling operation is commanded to the cargo handling device that has completed the cargo handling operation and is quickly moved to the storage position where the cargo handling operation should be performed. In other words, in view of the work status of each cargo handling equipment and the status of various work, work with optimal efficiency is assigned.

  In addition, the container chassis operation management system according to the invention of claim 3 is characterized in that the cargo handling equipment is equipped with a DGPS to detect the position at the time.

  For efficient operation of the cargo handling equipment, it is necessary to grasp the cargo handling equipment that can be quickly moved to the work position of the cargo handling work required to be performed at that time. Since the notification of completion of work is notified from the cargo handling equipment to the container yard management server, the position of the cargo handling equipment at that time can be grasped, but the cargo handling equipment moves as time elapses. For this reason, a DGPS (Differential Global Positioning System) is mounted on the cargo handling device to determine the position of the cargo handling device.

  According to the container chassis operation management system of the present invention, it is possible to grasp the situation of the chassis and the cargo handling equipment, standby work, etc., and to operate the chassis and the cargo handling equipment under optimum conditions for the standby work. The container terminal can be operated efficiently. In addition, when work occurs suddenly such as an urgent thing, the work can be processed by manual operation. Therefore, it is possible to quickly cope with unexpected situations such as sudden work while efficiently performing work that is scheduled in advance.

  In addition, according to the container chassis operation management system of the second aspect of the invention, it is possible to predict and wait for the visit time of the foreign chassis, so the cargo handling work can be performed more efficiently. Moreover, the work can be performed in the same manner as the campus chassis.

  In addition, according to the container chassis operation management system of the third aspect of the invention, the position of the cargo handling device can be grasped in real time, so that the procedure of the cargo handling operation can be set reliably.
