Technical Field

[0001] The present invention relates to automated wharf technology, and more specifically, to a method and system for automatically changing and gradually specifying instructions for automated wharf operation machinery. Background Art

[0002] During on-site operations at automated terminals, accurate and timely operating instructions are crucial to improving the efficiency of operating machinery and reducing unnecessary waiting between operating machinery.

[0003] The operating instructions that the current system sends to the operating machinery generally specify all the details of the instructions from the beginning. For example, the destination location that the system sends to the automated horizontal transport machinery is clearly defined as Bay, Column, and Layer from the beginning. However, since the execution of the instruction by the operating machinery is a process that will last for a certain period of time, and some events may occur during this period, such as the rear vehicle arriving first, etc., which may make the current operating instruction decided previously not necessarily the most optimized in the later stage of execution, and frequently changing the instruction will increase the pressure on the system. Summary of the invention

[0004] In view of the above-mentioned defects existing in the prior art, the purpose of the present invention is to provide a method and system for automatic change and gradual detailing of instructions for automated terminal operating machinery, which can avoid frequent changes of operating instructions in the system, ensure the execution of the scheduling system, and ensure the operating efficiency of the operating machinery.

[0008] Preferably, the method for automatically changing and gradually specifying instructions for automated terminal operation machinery specifically includes the following process:

[0010] The scheduling decision unit is triggered by one or more real-time status events of the working machines, and makes decisions and outputs an execution task list of the working machines;

[0011] The scheduling and dispatching unit is triggered by a real-time status event of one or more of the operating machines, reads the decision result of the scheduling and decision-making unit, and then dispatches the operating instructions to the corresponding operating machines in whole or one by one according to the configuration parameters and business logic;

[0012] The ECS (Equipment Control System) module receives and further decomposes the job instructions issued by the scheduling and dispatching unit.

[0013] Preferably, when the scheduling dispatching unit reads the decision result of the scheduling decision unit, the reading order is the first job task in the decided task list.

[0014] Preferably, the ECS module obtains real-time data of each of the operating machines from the bottom layer and feeds it back to the monitoring unit.

[0039] Example

[0040] In this embodiment, after the operation instruction is dispatched to the operation machine, the scheduling module in the TOS system will update some details of the operation instruction according to the latest decision result in the scheduling module, the execution process and execution status of the current operation instruction. Which details of the instruction to be updated are related to the execution process of the operation machine (task) and can be configured, as follows:

[0041] 1.1, Automatic change of instructions

[0042] 1.1.1, Change of task location (step by step)

[0043]

[0044] The slot location can be determined by SLOT. <location> . <area> . <bay> . <lane> . <tier>express.

[0045] 1) Task changes are for work machines that have been bound to work orders.

[0046] For the idle operating machinery, it is only nominally bound to an Order instruction, and is <location> . <area> . <bay>The order is gradually determined until the final position, that is, the operating machine may be replaced by other tasks with the same partial position information during the execution process;

[0047] For heavy-loaded operating machinery, the operating machinery's task box will not change, but its drop box location may change based on the dispatching or other module decisions;

[0048] The step-by-step breakdown of the location can be configured as follows

[0049] Note:

[0050]

[0051] 2) The location enumeration values ​​are gradually refined in the following order: location>area>bay>lane>tier. When the operating machine leaves the configured "last allowed change of mechanical segmentation process", the configured "change location (ToAlerateLocation)" and the position before the sorting will no longer be allowed to be changed by the subsequent dispatching instruction automatic change service, unless the TOS actively initiates the change instruction or the operating machine changes the task.

[0052] 3)3. Position <location>The change in the dispatching module means the change of the task type. That is, when the machine is in the corresponding "last allowed change of machine segmentation process", the machine is allowed to participate in the vehicle selection module of the dispatching.

[0053] 4) The change of task location includes the change of the task starting location and the task destination location:

[0054] a) The change of the task starting position is for an empty vehicle, that is, the change of the task starting position occurs during the entire empty vehicle movement process.

[0055] Example: The following table shows the strategy configuration for changing the starting position of an IGV task.

[0056]

[0057] i) When the instruction dispatching module dispatches the latest decision result of the scheduling to the IGV, the module will determine the type of task to be performed by the IGV, as well as the task starting block (shipping, container loading) or vessel, and no further changes are allowed;

[0058] ii) When the module detects that the IGV is 5 seconds away from reaching the box area, the module will determine the destination Bay where the IGV has arrived at the box area and no further changes are allowed;

[0059] iii) When the module detects that the IGV is 1 second away from reaching the destination Bay, the module will determine the final destination lane and tier, that is, determine the final task box to be operated;

[0060] iv) Similar to the IGV that can be configured to perform unloading tasks, the details of the unloading QC can be changed;

[0061] v) The completion time of the current mechanical segmentation process can be estimated by the expected completion time of the ECS, and the expected completion time of the ECS can also be specific to the segmentation process.

[0062] B) The change of the task destination location is for heavy vehicles. It may mainly occur in unloading, loading containers, moving containers within the yard and other working conditions. At this time, the module needs the real-time decision results of the expert dispatching system.

[0063] 1.1.2, Configuration of releasing (canceling current tasks) and reassigning tasks for operating machinery

[0064] Automatic cancellation is only for the machines that are currently bound to the order but are still in the idle state.

[0065]

[0066] These operating machines for elimination tasks will enter the vehicle selection range in the scheduling module;

[0067] 1.1.3, Automatic change of task plan start (completion) time

[0068] During the loading operation, the planned start time (earliest start time) of the loading WI in the CWP operation sequence reflects the urgency of the WI task in the plan, which may affect the possibility of obtaining the response of the horizontal transport machinery and other operation machinery. Therefore, the real-time and accuracy of the estimation of the time attributes related to the WI task is very important in scheduling.

[0069] (WI) The execution time of the task plan is affected by factors such as the change of the CWP plan itself and the current completion progress of the predecessor task. When these factors change and corresponding events are generated, the attribute value can be re-estimated in real time by calling the corresponding module.

[0070] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.< / location> < / bay> < / location> < / tier> < / lane> < / bay> < / location>
