Description

Technical Field

[0001] The present invention relates to the technical field of automated control of gantry cranes, and particularly to a gantry crane control system based on a remote operation console and a method for binding and allocating the remote operation console to the gantry crane. Background Art

[0002] In the operation scenario of an automated container terminal, the dual - trolley quay - side container handling mode is mainstream. In this mode, the two trolleys of the automated gantry crane (the two trolleys include the gantry trolley and the main trolley) each perform their own functions. The gantry trolley operates automatically throughout the process, while the main trolley flexibly combines manual operation and automatic operation. According to detailed statistics, in the process of the main trolley completing one operation round, the proportion of the time occupied by manual operation is about 1 / 4, while the proportion of the time of automatic operation is as high as 3 / 4.

[0003] Currently, the terminal follows the traditional method of binding and allocating gantry cranes, that is, only one remote control console can establish a binding connection with one gantry crane. When the main trolley enters the manual operation stage, the remote control console will take over the control authority and be responsible for the information interaction and transmission with the gantry crane. However, this mode has significant drawbacks. Since the main trolley is in the automatic operation state most of the time, the remote control console bound to it is idle for 3 / 4 of the time, resulting in a waste of remote control console resources.

[0004] For an automated container terminal, improving the operation efficiency of gantry cranes is the key to reducing operation costs. In order to optimize the man - machine ratio and fully explore the potential of resources, it is extremely urgent to design a more scientific and reasonable method for binding and allocating gantry cranes to remote operation consoles. Summary of the Invention

[0005] Aiming at the problem that the traditional method of binding and allocating gantry cranes in the terminal causes the remote control console bound to the gantry crane to be idle during the automatic operation of the main trolley, resulting in a waste of remote control console resources, the present invention provides a gantry crane control system based on a remote operation console and a method for binding and allocating the remote operation console to the gantry crane.

[0006] In a first aspect, the technical solution of the present invention provides a gantry crane control system based on a remote operation console. The number of remote operation consoles is N, and the number of gantry cranes is M. The N remote operation consoles are divided into P groups. One of the remote operation consoles in each group is defined as the main control operation console, and the rest are auxiliary operation consoles; the main control operation console in each group is unique, and there is at least one auxiliary operation console. The number of gantry cranes in each group is determined according to the proportion of the automatic and manual operation time of the gantry crane. The system further includes an operation console controller; each gantry crane is provided with a gantry crane controller. The operation console controller receives the status of the gantry crane fed back by the gantry crane controller, and controls the binding of the gantry crane in the manual state to the main operation console in its own group of gantry cranes, and controls the gantry crane through the main operation console; it controls the binding of the suspension bridge in the set operation state or fault state to the auxiliary operation console in its own group of gantry cranes.

[0007] As a further limitation of the technical solution of the present invention, the auxiliary operation console in the group is for exclusive use in its own group or shared with other groups.

[0008] As a further limitation of the technical solution of the present invention, there are two touch buttons on each remote operation console, namely the release button and the transfer to auxiliary button; After triggering the release button, the binding relationship between the current gantry crane and the operation console is released, but the allocation relationship between the gantry crane and the operation console remains unchanged, and the gantry crane runs independently; the operation console includes a main operation console and an auxiliary operation console; After triggering the transfer to auxiliary button, the current bound gantry crane is unbound from the main operation console, and the current gantry crane is transferred to the waiting queue of the auxiliary operation console.

[0009] As a further limitation of the technical solution of the present invention, when the gantry crane is in the set operation state or fault state, it is transferred and bound to the auxiliary operation console for processing. When the set operation is completed or the fault is eliminated, the binding relationship is released from the auxiliary operation console and returns to the main operation console.

[0010] As a further limitation of the technical solution of the present invention, the priority of the auxiliary operation console in each group is set. When a gantry crane in the set operation state or fault state is transferred out from the main operation console, it is bound to the auxiliary operation console with the highest priority among the idle auxiliary operation consoles.

[0011] As a further limitation of the technical solution of the present invention, when the gantry crane QC1 is in the manual state, the operation console controller automatically binds it to the main operation console in the group. After completing the manual part, the gantry crane enters the automatic state. After receiving the trigger information of the release button, the current binding relationship is released, and the main operation console is released; When the operation console controller detects that the main operation console is in the unbound state, it will automatically reassign the next gantry crane in the manual state to be bound to the main operation console; After the gantry crane QC1 completes the automatic part and starts to enter the manual part, the operation console controller queues the gantry crane QC1 into the manual state queue and waits to be rebound after the main operation console in its group is released.

[0012] As a further limitation of the technical solution of the present invention, when the operation console controller receives feedback from the bridge crane controller that the bridge crane is in a set state or a fault state, the operation console controller transfers the bridge crane to the auxiliary operation console waiting team, and automatically binds to the auxiliary operation console when there is an idle auxiliary operation console. After completing the set state operation and receiving the trigger signal of the release button, the operation console controller automatically transfers the bridge crane back to the main control operation console; After the operating console controller detects that the auxiliary operating console is in the released state, it will automatically bind the next bridge crane in the set state or fault state to the auxiliary operating console.

[0013] As a further limitation of the technical solution of the present invention, the system also includes a video monitoring subsystem. When the operating console is bound to the bridge crane, the operating console controller sends a switching signal to the video monitoring subsystem. The video monitoring screen on the operating console displays the information and picture of the corresponding bridge crane. When the bound bridge crane is changed, the picture automatically switches to the corresponding bridge crane.

[0014] In a second aspect, the technical solution of the present invention provides a method for binding and allocating a remote operating console and a suspension bridge applied to the system of the first aspect, wherein each remote operating console is provided with a release button and a transfer auxiliary button, and the method comprises the following steps: When the bridge crane QC1 is in manual state, the console controller automatically binds it to the main control console in the group. After completing the manual part, the bridge crane enters the automatic state. After receiving the trigger information of the release button, the current binding relationship is released and the main control console is released; When the console controller detects that the main control console is in an unbinding state, it will automatically reallocate the next bridge crane in manual state to be bound to the main control console; After the bridge crane QC1 completes the automatic part and starts to enter the manual part, the console controller puts the bridge crane QC1 into the manual state queue and waits for the master console in the group to release it before binding it again; When the bridge crane is in a set operation state or a fault state, it is transferred and bound to the auxiliary operation console for processing. When the set operation is completed or the fault is eliminated, the binding relationship is released from the auxiliary operation console and returned to the main control console.

[0015] As a further limitation of the technical solution of the present invention, when the bridge crane is in a set operation state or a fault state, the step of switching and binding to the auxiliary operation console for processing, and when the set operation is completed or the fault is eliminated, the binding relationship is released from the auxiliary operation console to the main control console includes: When the console controller receives feedback from the gantry crane controller that the gantry crane is in the set state or the fault state, the console controller transfers the gantry crane to the waiting queue of the auxiliary console. After there is an idle auxiliary console, it is automatically bound to the auxiliary console. After completing the operation in the set state and the console controller receives the trigger signal of the release button, it automatically transfers the gantry crane back to the main control console; After the console controller detects that the auxiliary console is in the release state, it will automatically bind the next gantry crane in the set state or the fault state to the auxiliary console.

[0016] The beneficial effects of the technical solution of the present invention are as follows: Divide N remote consoles into P groups, and determine the number of gantry cranes in each group according to the proportion of the automatic and manual operation time of the gantry crane. It avoids the situation that the remote console is idle for a long time due to the automatic operation of the gantry crane in the traditional mode, greatly improves the resource utilization rate of the remote console, reduces resource waste, and realizes the scientific and efficient allocation of resources. Clearly define the division of labor between the main control console and the auxiliary console in each group, with the main control console being unique and at least one auxiliary console. When the gantry crane is in the manual state, the console controller binds it to the main control console of its own group to achieve targeted control. With the help of the auxiliary console, reserve space for possible task expansion and collaborative operation, greatly improving the flexibility and efficiency of system control. By optimizing the binding relationship between the remote console and the gantry crane, the operator can respond to the manual operation requirements of the gantry crane more quickly and effectively, reducing waiting time and operation delays, thereby improving the overall operation efficiency of the gantry crane and providing strong support for reducing the operation cost of the automated terminal.

[0022] To make the objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the specific embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0023] As Figure 1 shown, an embodiment of the present invention provides a gantry crane control system based on a remote operation console. The number of remote operation consoles is N, and the number of gantry cranes is M. The N remote operation consoles are divided into P groups. One of the remote operation consoles in each group is defined as the main control operation console, and the rest are auxiliary operation consoles; the main control operation console in each group is unique, and there is at least one auxiliary operation console. The number of gantry cranes in each group is determined according to the ratio of the automatic and manual operation time of the gantry crane. The system further includes an operation console controller; each gantry crane is provided with a gantry crane controller. The operation console controller receives the gantry crane status feedback by the gantry crane controller, and controls to bind the gantry crane in the manual state to the main control operation console in its own group of the gantry crane, and controls the gantry crane through the main control operation console; controls to bind the gantry crane in the set operation state or the fault state to the auxiliary operation console in its own group of the gantry crane.

[0024] In the scenario of an automated container terminal, the number N of remote operation consoles and the number M of gantry cranes are determined. For example, the terminal has 10 remote operation consoles (N = 10) and 20 gantry cranes (M = 20).

[0025] According to the statistical data on the operation of gantry cranes in the past, the ratio of the automatic and manual operation time of the gantry crane is determined. Suppose that after statistics, the ratio of the automatic operation time of a certain type of gantry crane is 75%, and the ratio of the manual operation time is 25%. According to factors such as the number N of remote operation consoles and the ratio of the operation time of the gantry crane, the N remote operation consoles are divided into P groups. For example, according to a certain algorithm and actual requirements, 10 remote operation consoles are divided into 5 groups (P = 5).

[0026] Specify a master operation console for each group, and the rest are auxiliary operation consoles. For example, among the 2 remote operation consoles (1 master and 1 auxiliary) in each group, one of them is randomly determined or determined according to factors such as the performance of the operation console as the master operation console. Install a gantry crane controller on each gantry crane, and this controller has the function of real-time monitoring the operating state of the gantry crane, including whether the gantry crane is currently in the automatic operation state or the manual operation state. The gantry crane controller continuously feeds back the gantry crane state information to the operation console controller. For example, when the gantry crane switches from the automatic operation to the manual operation state, the gantry crane controller immediately sends a state change signal to the operation console controller. The operation console controller receives the gantry crane state information fed back from each gantry crane controller. According to the received information, it judges whether the gantry crane is in the manual state. If it is detected that a certain gantry crane is in the manual state, the operation console controller determines the group to which the gantry crane belongs according to the preset rules. The operation console controller controls to bind the gantry crane in the manual state to the master operation console in its own group.

[0027] For example, if gantry crane No. 3 is in the manual state and its group is Group 2, the operation console controller will establish a connection between gantry crane No. 3 and the master operation console of Group 2. After the master operation console is bound to the gantry crane in the manual state, the operator can precisely control the gantry crane through the master operation console to realize operations such as cargo loading and unloading. With factors such as changes in the terminal business volume and changes in the gantry crane operation mode, the proportion of the automatic and manual operation time of the gantry crane may change. At this time, the group division and the number of gantry cranes in each group can be re-evaluated and adjusted according to the new time proportion. For example, if the type of cargo at the terminal changes during a certain period, resulting in the proportion of the manual operation time of the gantry crane rising to 35%, then recalculate and adjust the gantry crane allocation of each group. During the operation of the system, if a certain master operation console fails or has too high a load, the operation console controller can re-designate the auxiliary operation console in the group as the master operation console to ensure the stable operation of the system. For example, if the master operation console of Group 3 issues a fault alarm, the operation console controller automatically switches the auxiliary operation console in this group to the master operation console and re-establishes the binding relationship with the corresponding gantry crane.

[0028] In some embodiments, the auxiliary operation console in the group is for the exclusive use of its own group or shared with other groups. Based on the scenarios described in the above embodiments, if the strategy of the auxiliary operation console being for the exclusive use of its own group is adopted, for example, according to a certain algorithm and actual requirements, 10 remote operation consoles are divided into 5 groups (P = 5), each group is equipped with 2 remote operation consoles, one of which is the master operation console and one is the exclusive auxiliary operation console.

[0029] If it is considered that the auxiliary operation console is shared with other groups, the groups may be divided according to factors such as the terminal operation area and the crane busyness. For example, 4 remote operation consoles are divided into 2 groups. The first group is equipped with 3 remote operation consoles (1 main control and 2 auxiliary), and the second group is equipped with 3 remote operation consoles (1 main control and 2 auxiliary). The auxiliary operation console equipped in the first group is shared with the second group, as Figure 2 shown. Inside the first group, there are also quay cranes QC1, QC2, and QC3; inside the second group, there are also quay cranes QC4, QC5, and QC6.

[0030] Designate a main control operation console for each group, and the rest are auxiliary operation consoles. For example, inside each group, determine the main control operation console according to factors such as the operation console performance and location.

[0031] Situation of exclusive use of the auxiliary operation console: If the group to which the quay crane in the manual state belongs adopts the strategy of exclusive use of the auxiliary operation console group, the operation console controller controls to bind the quay crane to the main control operation console in the group. For example, if quay crane No. 3 is in the manual state and its affiliated group is the second group, the operation console controller will establish a connection between quay crane No. 3 and the main control operation console of the second group, and the auxiliary operation consoles of this group are only reserved for this group.

[0032] Situation of shared auxiliary operation console: If the main control operation console of the group to which the quay crane in the manual state belongs is busy or fails, and there is a strategy of shared auxiliary operation console, the operation console controller first tries to bind the quay crane to the main control operation console of this group. If the binding fails, the operation console controller will search for a sharable auxiliary operation console according to the sharing rules, and establish a connection between the quay crane and the main control operation console of the group where the sharable auxiliary operation console is located (at this time, this auxiliary operation console participates in the control of this quay crane). For example, when quay crane No. 5 in the first group is operating manually and the main control operation console fails, and there is a sharable auxiliary operation console in the second group and the sharing conditions are met, the operation console controller will establish an association between quay crane No. 5 and the main control operation console of the second group and this sharable auxiliary operation console.

[0033] After the main control operation console is bound to the quay crane in the manual state, the operator can precisely control the quay crane through the main control operation console to realize operations such as cargo handling. When the shared auxiliary operation console participates in the control, the auxiliary operation console can assist the main control operation console in data monitoring, operation assistance, etc. to jointly complete the control of the quay crane.

[0034] Correspondingly, with the changes in factors such as the terminal business volume and the quay crane operation mode, the proportion of the automatic and manual operation time of the quay crane may change. At this time, the group division and the number of quay cranes in each group can be re-evaluated and adjusted according to the new time proportion.

[0035] Exclusive use: For example, if the type of cargo at the terminal changes over a period of time, causing the proportion of manual operation time of the bridge crane to rise to 35%, for groups that use exclusive auxiliary operating desks, it may be necessary to readjust the number of groups or the number of remote operating desks within each group to better match the manual operation needs of the bridge crane.

[0036] Sharing: When the proportion of manual operation time changes, in addition to adjusting the number of groups and the allocation of remote operation stations, it is also necessary to re-evaluate the sharing rules and sharing scope of auxiliary operation stations. For example, if the demand for manual operations increases, it may be necessary to expand the sharing scope of some auxiliary operation stations to meet the control needs of more manual operations of bridge cranes.

[0037] During system operation, if a main control console fails or is overloaded, the console controller can re-assign an auxiliary console within the group as the main control console to ensure stable operation of the system.

[0038] Exclusive use: For groups that use their own auxiliary operating consoles, if the main operating console fails, the auxiliary operating console of the group will be directly switched to the main operating console, and the binding relationship with the corresponding bridge crane will be re-established.

[0039] Sharing situation: If the main control console of a group fails in the sharing mode, in addition to switching the auxiliary control console of the group to the main control, it is also necessary to consider whether to adjust the sharing rules, such as whether to temporarily expand the sharing scope of other group auxiliary control consoles to the bridge crane of the group to deal with emergencies. For example, if the main control console of the third group fails, in addition to switching the auxiliary control console of the group to the main control, some auxiliary control consoles of the first group can be temporarily allowed to provide support for the bridge crane of the third group under certain conditions.

[0040] In some embodiments, each remote operation console has two touch buttons, namely a release button and a transfer auxiliary button; After the release button is triggered, the current binding relationship between the bridge crane and the operating console is released, but the allocation relationship between the bridge crane and the operating console does not change, and the bridge crane operates independently; the operating console includes a main control console and an auxiliary operating console; After triggering the auxiliary button, the currently bound bridge crane will be untied from the main control console, and the current bridge crane will be transferred to the auxiliary control console waiting queue.

[0041] When the bridge crane is in a set operation state or a fault state, it is transferred and bound to the auxiliary operation console for processing. When the set operation is completed or the fault is eliminated, the binding relationship is released from the auxiliary operation console and returned to the main control console.

[0042] Set the priority of the auxiliary operation console in each group. When a bridge crane with a set operation status or fault status is transferred out from the main control console, it is bound to the auxiliary operation console with the highest priority among the idle auxiliary operation consoles.

[0043] When the bridge crane QC1 is in the manual state, the console controller automatically binds it to the main console in the group. After completing the manual part, the bridge crane enters the automatic state. After receiving the trigger information of the release button, the current binding relationship is released and the main console is released; When the console controller detects that the main console is in the unbound state, it will automatically reassign the next bridge crane in the manual state to be bound to the main console; After the bridge crane QC1 completes the automatic part and starts to enter the manual part, the console controller queues the bridge crane QC1 in the manual state queue and waits to be rebound after the main console in the group is released.

[0044] When the console controller receives the feedback from the bridge crane controller that the bridge crane is in the set state or the fault state, the console controller transfers the bridge crane to the auxiliary console waiting queue. After there is an idle auxiliary console, it is automatically bound to the auxiliary console. After completing the set state operation and the console controller receives the trigger signal of the release button, it automatically transfers the bridge crane back to the main console; After the console controller detects that the auxiliary console is in the released state, it will automatically bind the next bridge crane in the set state or the fault state to the auxiliary console.

[0045] It should be noted that in the embodiments of the present invention, whether it is the main console or the auxiliary console, when the release button is triggered, the binding relationship between the current bridge crane and the console will be immediately released. However, it should be noted that the pre-set allocation relationship between the bridge crane and the console will not change, and at this time the bridge crane enters the independent operation state. For example, if the bridge crane QC1 is bound to a certain main console for operation and the operator triggers the release button, QC1 will disconnect from the main console and start to continue working according to its own pre-set independent operation program, and it still belongs to the originally assigned group.

[0046] When the transfer to auxiliary button is triggered on the console, the bridge crane currently bound to the main console will be unbound and then transferred to the auxiliary console waiting queue. This mechanism provides flexibility for dealing with different operation situations and resource allocation. For example, in a specific operation scenario, the operator believes that a certain bridge crane needs to be further processed by the auxiliary console, and can trigger the transfer to auxiliary button to transfer the bridge crane from the main console to the waiting queue of the auxiliary console.

[0047] When the bridge crane is in a set operation state (such as special operations such as loading and unloading of special cargoes) or a fault state, the system will automatically transfer its binding relationship to the auxiliary operation console for processing. Once the set operation is successfully completed or the fault is successfully eliminated, the binding relationship of the bridge crane will be released from the auxiliary operation console and returned to the main control console. For example, when the bridge crane QC2 fails during operation, the console controller will automatically transfer QC2 from the main control console and establish a binding relationship with the auxiliary operation console after detecting it, so that the operator can troubleshoot and handle the fault on the auxiliary operation console. When the fault is eliminated, QC2 will be re-bound back to the main control console and continue normal operation. In order to more efficiently manage the resource allocation of auxiliary operation consoles, the system sets a priority for the auxiliary operation consoles in each group. When a bridge crane in a set operation state or a fault state is transferred from the main control console, the system will first bind it to the idle auxiliary operation console with the highest priority. This ensures that important or urgent bridge crane tasks can be processed in a timely manner. For example, there are three auxiliary operating consoles in the group, each with a different priority. When the bridge crane QC3 needs to be transferred from the main control console due to special operations, if there are two auxiliary operating consoles idle at this time, the system will automatically bind QC3 to the idle auxiliary operating console with the highest priority.

[0048] When the bridge crane QC1 is in the manual state, the console controller will automatically bind it to the main control console in the group according to the preset rules. The operator performs the manual operation part of QC1 through the main control console. After completing the manual part of the operation, the bridge crane QC1 enters the automatic state. At this time, if the operator triggers the release button, the system will immediately release the current binding relationship between QC1 and the main control console after receiving the trigger information, thereby releasing the main control console so that it can be assigned to other bridge cranes that need manual operation. When QC1 completes the automatic part of the operation and starts to enter the manual part again, the console controller will put the bridge crane QC1 into the manual state queue. It will wait in the queue until the main control console in the group it belongs to is released again, and then it will be bound again to continue to complete the manual operation task. The specific allocation conversion diagram is shown as follows. Figure 3 shown.

[0049] When the console controller receives the feedback from the gantry crane controller that the gantry crane is in the set state or the fault state, it will transfer the gantry crane to the waiting queue of the auxiliary console. Once there is an idle auxiliary console, the system will automatically bind the gantry crane to the idle auxiliary console. For example, if the gantry crane QC4 fails, the console controller will queue it in the waiting queue of the auxiliary console. When there is an idle auxiliary console, it will automatically bind QC4 to it for fault handling. After the gantry crane completes the operation in the set state and the console controller receives the trigger signal of the release button, it will automatically transfer the gantry crane back to the main control console. At the same time, when the console controller detects that the auxiliary console is in the release state, it will automatically bind the next gantry crane in the set state or the fault state to the auxiliary console to ensure the full utilization of the auxiliary console resources and guarantee the efficient operation of the entire gantry crane operation system.

[0050] In some embodiments, the system further includes a video monitoring subsystem. When the console is bound to the gantry crane, the console controller sends a switching signal to the video monitoring subsystem, and the video monitoring screen on the console displays the information and pictures of the corresponding gantry crane. When the bound gantry crane is replaced, the screen automatically follows and switches to the corresponding gantry crane.

[0051] It should be noted that in the facility construction stage of the automated container terminal in the embodiments of the present invention, the cameras of the video monitoring subsystem are reasonably installed at key positions of each gantry crane, such as the lifting point of the gantry crane, near the trolley running track, and the cargo loading and unloading area, etc., to ensure that all links of the gantry crane operation can be comprehensively captured. At the same time, the video monitoring subsystem is integrated with the entire gantry crane control system, so that the video monitoring subsystem can receive signals from the console controller and transmit the corresponding video pictures to each remote console.

[0052] On each remote console, through system configuration, the console is associated with the video monitoring subsystem. Ensure that when the console establishes a binding relationship with the gantry crane, it can accurately send a switching signal to the video monitoring subsystem and can receive and display the corresponding gantry crane information and pictures from the video monitoring subsystem.

[0053] When the gantry crane (such as gantry crane QC1) is in the manual state, the console controller automatically binds it to the main control console (assumed to be console OP1) in the group according to the preset rules. At the same time as the binding is completed, the console controller immediately sends a switching signal to the video monitoring subsystem. This signal contains identification information related to the gantry crane, such as the gantry crane number (e.g., QC1), etc., so that the video monitoring subsystem can accurately identify the target gantry crane to be switched.

[0054] After receiving the switching signal, the video monitoring subsystem quickly selects the video images corresponding to the bridge crane QC1 from the images collected by many cameras according to the bridge crane identification information in the signal, and transmits these images and related bridge crane information (such as the current operation status of the bridge crane, load data, etc.) to the operating console OP1. After the operating console OP1 receives the information from the video monitoring subsystem, it displays it in the video monitoring screen area on the operating console. At this time, the operator can intuitively see the real-time operation screen and related operation information of the bridge crane QC1 on the operating console OP1, providing strong visual support for their operation of the bridge crane.

[0055] Assume that the bridge crane QC1 completes the manual operation part and enters the automatic state. The operator triggers the release button to release the binding relationship between the bridge crane QC1 and the operating console OP1. Subsequently, when the operating console controller detects that the main control console OP1 is in the unbinding state, it will automatically bind the next bridge crane in the manual state (such as bridge crane QC2) to the main control console OP1. At the moment when the bridge crane QC2 is successfully bound to the operating console OP1, the operating console controller sends a switching signal to the video monitoring subsystem again. This signal also carries the identification information of the bridge crane QC2. After receiving the new switching signal, the video monitoring subsystem immediately stops transmitting the video images and information of the bridge crane QC1 to the operating console OP1, and quickly switches to the relevant video images and information of the bridge crane QC2, and then transmits it to the operating console OP1.

[0056] The video surveillance screen on the operating console will automatically switch. The operator can see the real-time operation screen and related information of the newly bound bridge crane QC2 on the same operating console without manual intervention, realizing seamless switching of the video surveillance screen and the bridge crane binding relationship, ensuring the operator's continuous monitoring and operation convenience of the bridge crane operation.

[0057] When the bridge crane (such as bridge crane QC3) is in a set operating state or a fault state, the console controller transfers it from the main control console (assumed to be console OP2) to the waiting queue of the auxiliary console. When there is an idle and highest-priority auxiliary console (assumed to be console OP3), the bridge crane QC3 is bound to the auxiliary console OP3. During the process of binding the bridge crane QC3 to the auxiliary console OP3, the console controller sends a switching signal to the video monitoring subsystem, informing it that the bridge crane QC3 has been bound to the auxiliary console OP3. After receiving the signal, the video monitoring subsystem adjusts the video transmission path and transmits the video image and relevant information of the bridge crane QC3 to the auxiliary console OP3. The video monitoring screen of the auxiliary console OP3 then displays the information and image of the bridge crane QC3, facilitating the operator to monitor the special operations or fault handling of the bridge crane QC3 on the auxiliary console.

[0058] When the bridge crane QC3 completes the set state operation or troubleshooting, and the console controller receives the trigger signal of the release button, the bridge crane QC3 is transferred back to the main control console OP2. At this time, the console controller sends a switching signal to the video monitoring subsystem again, and the video monitoring subsystem re-transmits the video image and information of the bridge crane QC3 back to the main control console OP2, and the video monitoring screen on the console is switched accordingly to ensure that the operator can continue to monitor the subsequent operations of the bridge crane QC3 on the main control console.

[0059] As Figure 4 shown, the technical solution of the present invention provides a method for binding and allocating a remote console and a suspension bridge applied to the system described in the first aspect. When each remote console is provided with a release button and a transfer-to-auxiliary button, the method includes the following steps: S1: When the console controller detects that the bridge crane QC1 is in the manual state, it automatically binds the bridge crane QC1 to the main control console in the group. After completing the manual part, the bridge crane QC1 enters the automatic state. After receiving the trigger information of the release button, the current binding relationship is released, and the main control console is released; S2: When the console controller detects that the main control console is in the unbound state, it will automatically re-allocate the next bridge crane in the manual state to be bound to the main control console; S3: After the bridge crane QC1 completes the automatic part and starts to enter the manual part, the console controller arranges the bridge crane QC1 in the manual state queue and waits to be re-bound after the main control console in the group is released; S4: When the console controller detects that the bridge crane is in a set operating state or a fault state, it switches the binding to the auxiliary console for processing. When the set operation ends or the troubleshooting is completed, the binding relationship is released from the auxiliary console and returns to the main control console.

[0060] In some embodiments, when the operating console controller detects that the bridge crane is in a set operation state or a fault state, the operation console controller switches to bind to the auxiliary operating console for processing. When the setting operation is completed or the fault is eliminated, the binding relationship is released from the auxiliary operating console to the main control console. The steps include: When the operation console controller receives feedback from the bridge crane controller that the bridge crane is in a set state or a fault state, the operation console controller transfers the bridge crane to the auxiliary operation console waiting team, and automatically binds to the auxiliary operation console when there is an idle auxiliary operation console. After completing the set state operation and receiving the trigger signal of the release button, the operation console controller automatically transfers the bridge crane back to the main control console; After the operating console controller detects that the auxiliary operating console is in the released state, it will automatically bind the next bridge crane in the set state or fault state to the auxiliary operating console.

[0061] It should be noted that the specific logic of the manual binding of the bridge crane with the main control console and subsequent operations in the embodiment of the present invention includes: When the bridge crane QC1 is in manual mode, the console controller automatically binds it to the main control console in the group.

[0062] After completing the manual operation, the bridge crane QC1 enters the automatic state.

[0063] If the trigger information of the release button is received, the current binding relationship between the bridge crane QC1 and the main control console is released, and the main control console is released.

[0064] When the console controller detects that the main control console is in an unbinding state, it automatically searches for the next bridge crane in manual state and binds it to the main control console.

[0065] After the bridge crane QC1 completes the automatic part and starts to enter the manual part, the console controller puts the bridge crane QC1 into the manual state queue. The bridge crane QC1 waits in the manual state queue until the master control console in the group is released, and then binds with the master control console again.

[0066] When the operation console controller receives feedback from the bridge crane controller that the bridge crane is in the set state or fault state, the bridge crane is transferred to the auxiliary operation console waiting queue. When there is an idle auxiliary operation console, the bridge crane in the waiting queue is automatically bound to the idle auxiliary operation console. After the bridge crane completes the set state operation, if the operation console controller receives the trigger signal of the release button, the bridge crane is automatically transferred back to the main control operation console.

[0067] When the operating console controller detects that the auxiliary operating console is in the released state, it automatically searches for the next bridge crane that is in the set state or fault state and binds it to the auxiliary operating console.
