Description

Technical Field

[0001] The present invention relates to the technical field of port terminals, and in particular to a port terminal quay crane control system and a computer program. Background Art

[0002] Quay crane, whose full name is dockside loading and unloading bridge, also known as bridge crane and shore container crane, is mainly used for loading and unloading operations of container ships and is crucial to improving the operating efficiency of container terminals.

[0003] In the existing automated port terminals, quay crane operations include automated operations and manual operations. Manual operations require the driver to operate through the console. Generally, an operating console in the remote control center is used to control the quay crane at a terminal site. The driver remotely controls the quay crane in the console. Only after the console is successfully bound to the quay crane can the quay crane be operated to carry out container operations. There are generally multiple ship berths and multiple quay cranes and their corresponding drivers at the front end of the terminal. The binding of the quay crane to the remote control console and the operation function mainly rely on the container management system of the port terminal.

[0004] The above-mentioned quay crane control method has the following problems: since a single operating console can only be bound to control a single quay crane, when the quay crane is waiting for the container truck to transport the container to the designated operation area or waiting for the transfer platform to complete the automated container grabbing, the driver and the operating console are in an idle state without any operation process and business, which wastes a lot of communication networks and human resources, resulting in a substantial increase in the terminal's operating costs.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0020] like Figure 1 As shown, a port terminal quay crane control system includes: a remote control center, an operation console connected to the remote control center, and a single PLC set on the quay crane; wherein, The remote control center is equipped with a remote control PLC, which can distribute quay crane operation tasks; The stand-alone PLC of the quay crane is connected to the remote control center; The remote control PLC and the stand-alone PLC of the quay crane are equipped with jump request and release request interfaces; When the quay crane needs to be operated manually by the driver, its stand-alone PLC sends a platform jump request to the remote control PLC. The remote control PLC selects an idle operating console and sends a connection binding request to the quay crane. The operating console connects and binds with the stand-alone PLC of the quay crane through the remote control center to control the quay crane operation. After the quay crane completes the manual operation, the stand-alone PLC of the quay crane sends a release request to the remote control PLC, and the remote control PLC sends a release request to the operating console to which it is connected. The operating console releases the connection with the quay crane and returns to the idle state. The operating console controls multiple quay cranes by switching the jump platforms and releasing them; The operating console is equipped with an interactive interface, through which the driver can control the quay crane operations and view relevant information about the quay crane.

[0021] There can be one or more operating stations, and one operating station can switch to control multiple quay cranes. Through the jump request, the operating station switches the quay crane to be controlled; the release request disconnects the control of the operating station and the quay crane.

[0022] The operating console switches to control the quay crane including: When there is only one operating console, when the remote control PLC receives a jump request from a stand-alone PLC of a quay crane, if the operating console is idle, it sends a connection binding request to the quay crane to the operating console; After receiving the connection binding request from the quay crane, the operation console reminds the driver through the interactive interface; The driver agrees to the connection binding request of the quay crane through the interactive interface of the operation console; The driver controls the quay crane for manual operations through the interactive interface of the operating console.

[0023] The operating console switches to control the quay crane including: When there are multiple operating platforms, the quay cranes and operating platforms shall be marked with serial numbers in sequence; When the remote control PLC receives a platform jump request from a stand-alone PLC of a quay crane, if the operating console with the same serial number as the quay crane is idle, the operating console with the same serial number is preferentially selected to send a connection binding request to the quay crane, otherwise other idle operating consoles are selected to send a connection binding request to the quay crane; After receiving the connection binding request from the quay crane, the operation console reminds the driver through the interactive interface; The driver agrees to the connection binding request of the quay crane through the interactive interface of the operation console; The driver controls the quay crane for manual operations through the interactive interface of the operating console.

[0024] In actual applications, when the quay crane needs the driver to manually complete the automatic operation preparation work, manually operate the main mechanism to eliminate the fault, etc., the single-machine PLC of the quay crane will send a jump request to the operator's console via the remote control PLC, such as Figure 2One such situation is shown.

[0025] In actual applications, the operating console has a touch screen for the driver to operate. When the operating console receives a platform jumping request sent by a quay crane, the request button on the touch screen flashes and the operating console speaker emits a prompt sound. The driver chooses to press the platform jumping request button to accept the connection binding of the quay crane. Then the driver can control the connected and bound quay crane to perform operations by operating the operating console.

[0026] In actual application, taking the example of two operating consoles switching to control three quay cranes, the operating console requests and allocations can be as follows: The three quay cranes are marked as machines 1, 2, and 3 respectively, and the two operating stations are marked as ROS1 and ROS2 respectively.

[0027] (1) Machine No. 1 requests that both ROS1 and ROS2 are idle.

[0028] The machine will connect to ROS1 first, and the driver must confirm receipt before it can operate.

[0029] (2) Machines 1 and 2 request that ROS1 and ROS2 are both idle.

[0030] The order is from ROS1 to ROS2 on a first-come, first-served basis, and the driver needs to confirm receipt before the operation can begin.

[0031] (3) Machines 1, 2, and 3 request that ROS1 and ROS2 are both idle.

[0032] First come first served, the first two will be connected in ROS order, and the driver needs to confirm receipt before operation. The last machine will wait in line.

[0033] (4) Single machine request, single ROS idle.

[0034] Direct connection requires the driver to confirm receipt before operation can begin.

[0035] (5) Two machines requesting, but only ROS is idle.

[0036] First, request the device to connect to the current ROS, and the driver needs to confirm the receipt before the operation can be carried out. The remaining machines queue up and wait for ROS to be idle.

[0037] (6) 1 machine request, both ROS1 and ROS2 are occupied.

[0038] The current machine continues to wait until the ROS station is idle.

[0039] The operation modes of the console include: MODE 0, 1, and 2. 0 means unallocated, 1 means allocated but not received, and 2 means allocated and received.

[0040] The connection modes of the operating console include: manual mode and automatic mode.

[0041] When the connection mode of the console is manual mode, the console maintains the current state. If the device is already connected, it will continue to connect to the current device, or it can actively release the current device. If the device is not connected, you can manually connect to the corresponding device, and you can also actively release it at any time.

[0042] When the connection mode of the operation console is automatic mode, the operation is performed according to the automatic request logic.

[0043] The console switches from manual mode to automatic mode: If ROS1 is in manual mode and connects to machine 1, ROS2 automatically connects to machine 2. If machine 3 requests the console, when ROS1 directly switches back to automatic mode, if machine 1 can be released, it will directly release machine 1 and immediately connect to machine 3; when ROS1 manually disconnects machine 1 and then switches back to automatic mode, it will immediately connect to machine 3.

[0044] The console switches from automatic mode to manual mode: When ROS1 is connected to machine 1, when it switches to manual mode, ROS1 remains connected to machine 1 and can actively connect and release operations. When it switches back to automatic mode, the console jumps again according to the request information.

[0045] The operating console switches to control the quay crane and also includes: After the driver controls the quay crane through the interactive interface of the console to complete the manual operation, the stand-alone PLC of the quay crane sends a release request to the remote control PLC; When the remote control PLC receives the release request sent by the stand-alone PLC of the quay crane, it sends the release request to the operating console to which it is connected and bound; After receiving the release request from the quay crane, the operation console reminds the driver through the interactive interface; The driver agrees to the release request of the quay crane through the interactive interface of the operating console, and the operating console returns to idle state.

[0046] In actual applications, when the driver completes the manual operation and the quay crane meets the automatic operation conditions, the stand-alone PLC of the quay crane will send a release request to the operator console where the driver is located through the remote control PLC, such as Figure 3 Shown is the system workflow before release.

[0047] When the quay crane instruction is in semi-automatic operation, the path from the starting point to the semi-automatic target position in this process is automatically generated by the anti-sway semi-automatic system, without the need for manual operation by the driver, and the operating console can be released.

[0048] When the quay crane is executing instructions and the platform is in the process of automatically placing containers, the quay crane will automatically grab and place containers on the platform during this process. No manual operation is required by the driver, and the operating console can be released.

[0049] When the quay crane completes the current instruction and there is no subsequent new instruction, the current quay crane can stand by and rest, and the operating console can be released.

[0050] Preferably, the port terminal quay crane control system further comprises: a monitoring module; wherein, The monitoring module includes cameras installed at various locations of the quay crane and a video management system deployed in the remote control center and the operating console; The driver can view the video footage of the quay crane site through the interactive interface of the console.

[0051] Preferably, the monitoring module further includes: When the operating console switches to control the quay crane, the interactive interface of the operating console can synchronously switch the video screen of the corresponding quay crane.

[0052] Preferably, the operating console is provided with a display screen Dataview in addition to a touch screen for the driver to operate. Dataview is the medium for the driver to view the operation status of the single machine and is the main channel for the driver to grasp the overall information of the current operating quay crane. In order to enable the driver to accurately know the current operating quay crane command status, or the driver needs additional information to judge the current operating machine, Dataview displays the information required by the driver through the interface with the single machine PLC.

[0053] In addition, Dataview can also display surveillance video for drivers to check the on-site situation.

[0054] The beneficial effects of this embodiment are: the system controls multiple quay cranes by switching between multiple operating consoles, maximizing the utilization rate between the driver, the operating console and the quay crane, improving the operating efficiency of the container terminal and reducing operating costs; through the monitoring module that can be switched synchronously, the driver can view the on-site situation in real time and make corresponding processing in time.

[0055] like Figure 4 As shown, a port terminal quay crane control system includes: a remote control center, an operation console connected to the remote control center, and a single PLC set on the quay crane; wherein, The remote control center is equipped with a remote control PLC, which can distribute quay crane operation tasks; The stand-alone PLC of the quay crane is connected to the remote control center; The remote control PLC and the stand-alone PLC of the quay crane are equipped with jump request and release request interfaces; When the quay crane needs to be operated manually by the driver, its stand-alone PLC sends a platform jump request to the remote control PLC. The remote control PLC selects an idle operating console and sends a connection binding request to the quay crane. The operating console connects and binds with the stand-alone PLC of the quay crane through the remote control center to control the quay crane operation. After the quay crane completes the manual operation, the stand-alone PLC of the quay crane sends a release request to the remote control PLC, and the remote control PLC sends a release request to the operating console to which it is connected. The operating console releases the connection with the quay crane and returns to the idle state. The operating console controls multiple quay cranes by switching the jump platforms and releasing them; The operating console is equipped with an interactive interface, through which the driver can control the quay crane operations and view relevant information about the quay crane.

[0056] There can be one or more operating stations, and one operating station can switch to control multiple quay cranes. Through the jump request, the operating station switches the quay crane to be controlled; the release request disconnects the control of the operating station and the quay crane.

[0057] The operating console switches to control the quay crane including: When there is only one operating console, when the remote control PLC receives a jump request from a stand-alone PLC of a quay crane, if the operating console is idle, it sends a connection binding request to the quay crane to the operating console; After receiving the connection binding request from the quay crane, the operation console reminds the driver through the interactive interface; The driver agrees to the connection binding request of the quay crane through the interactive interface of the operation console; The driver controls the quay crane for manual operations through the interactive interface of the operating console.

[0058] The operating console switches to control the quay crane including: When there are multiple operating platforms, the quay cranes and operating platforms shall be marked with serial numbers in sequence; When the remote control PLC receives a platform jump request from a stand-alone PLC of a quay crane, if the operating console with the same serial number as the quay crane is idle, the operating console with the same serial number is preferentially selected to send a connection binding request to the quay crane, otherwise other idle operating consoles are selected to send a connection binding request to the quay crane; After receiving the connection binding request from the quay crane, the operation console reminds the driver through the interactive interface; The driver agrees to the connection binding request of the quay crane through the interactive interface of the operation console; The driver controls the quay crane for manual operations through the interactive interface of the operating console.

[0059] In actual applications, when the quay crane needs the driver to manually complete the automatic operation preparation work, manually operate the main mechanism to eliminate the fault, etc., the single-machine PLC of the quay crane will send a jump request to the operator's console via the remote control PLC, such as Figure 2 One such situation is shown.

[0060] In actual applications, the operating console has a touch screen for the driver to operate. When the operating console receives a platform jumping request sent by a quay crane, the request button on the touch screen flashes and the operating console speaker emits a prompt sound. The driver chooses to press the platform jumping request button to accept the connection binding of the quay crane. Then the driver can control the connected and bound quay crane to perform operations by operating the operating console.

[0061] In actual application, taking the example of two operating consoles switching to control three quay cranes, the operating console requests and allocations can be as follows: The three quay cranes are marked as machines 1, 2, and 3 respectively, and the two operating stations are marked as ROS1 and ROS2 respectively.

[0062] (1) Machine No. 1 requests that both ROS1 and ROS2 are idle.

[0063] The machine will connect to ROS1 first, and the driver must confirm receipt before it can operate.

[0064] (2) Machines 1 and 2 request that ROS1 and ROS2 are both idle.

[0065] The order is from ROS1 to ROS2 on a first-come, first-served basis, and the driver needs to confirm receipt before the operation can begin.

[0067] First come first served, the first two will be connected in ROS order, and the driver needs to confirm receipt before operation. The last machine will wait in line.

[0068] (4) Single machine request, single ROS idle.

[0069] Direct connection requires the driver to confirm receipt before operation can begin.

[0070] (5) Two machines requesting, but only ROS is idle.

[0071] First, request the device to connect to the current ROS, and the driver needs to confirm the receipt before the operation can be carried out. The remaining machines queue up and wait for ROS to be idle.

[0072] (6) 1 machine request, both ROS1 and ROS2 are occupied.

[0073] The current machine continues to wait until the ROS station is idle.

[0074] The operation modes of the console include: MODE 0, 1, and 2. 0 means unallocated, 1 means allocated but not received, and 2 means allocated and received.

[0075] The connection modes of the operating console include: manual mode and automatic mode.

If the device is already connected, it will continue to connect to the current device, or it can actively release the current device. If the device is not connected, you can manually connect to the corresponding device, and you can also actively release it at any time.

[0077] When the connection mode of the operation console is automatic mode, the operation is performed according to the automatic request logic.

[0078] The console switches from manual mode to automatic mode: If ROS1 is in manual mode and connects to machine 1, ROS2 automatically connects to machine 2. If machine 3 requests the console, when ROS1 directly switches back to automatic mode, if machine 1 can be released, it will directly release machine 1 and immediately connect to machine 3; when ROS1 manually disconnects machine 1 and then switches back to automatic mode, it will immediately connect to machine 3.

[0079] The console switches from automatic mode to manual mode: When ROS1 is connected to machine 1, when it switches to manual mode, ROS1 remains connected to machine 1 and can actively connect and release operations. When it switches back to automatic mode, the console jumps again according to the request information.

[0080] The operating console switches to control the quay crane and also includes: After the driver controls the quay crane through the interactive interface of the console to complete the manual operation, the stand-alone PLC of the quay crane sends a release request to the remote control PLC; When the remote control PLC receives the release request sent by the stand-alone PLC of the quay crane, it sends the release request to the operating console to which it is connected and bound; After receiving the release request from the quay crane, the operation console reminds the driver through the interactive interface; The driver agrees to the release request of the quay crane through the interactive interface of the operating console, and the operating console returns to idle state.
