For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
Fig. 1 is a flow diagram of some embodiments of a transport task scheduling method of the present disclosure. This embodiment is performed by an upper control system.
At step 110, the status of the receiving dock, the handling apparatus, and the put dock is obtained.
In some embodiments, real-time monitoring of whether cargo is being transported to the receiving dock, whether the handling equipment is idle, and whether the put dock is idle.
In some embodiments, the relevant information is stored by the underlying equipment control system, e.g., the PLC, at the pick-up station, the handling equipment, and the put-off station, respectively. For example, the pick-up station information includes a station identifier, a task number, an origination station, a destination station identifier, a request bit flag, and a response bit flag. The put station information includes a station identification and a task number. The station id is, for example, a station number, the starting station refers to the pick-up address of the transport apparatus, and the destination station refers to the drop-off address of the transport apparatus.
The carrier information includes a device identifier, a task number, a cargo number, an origin station, a destination station, an application bit flag, and a response bit flag. The handling device is, for example, a shuttle car, and the device identification is, for example, a device number.
In some embodiments, it is detected by a photocell sensing device whether cargo is being transported to the pick-up station.
In step 120, when the receiving platform is in a state of waiting for executing the receiving request task, a transporting task of the receiving platform is formed and written into a task list, wherein the transporting task includes a task priority, a receiving platform identifier and a target put platform identifier.
In some embodiments, the handling task further comprises a task state, wherein the task state is an unexecuted state when the handling task is formed; when the conveying task is distributed to the conveying equipment, the task state is an executing state; and after the transporting equipment transports the goods from the goods receiving platform to the target goods placing platform, the task state is a finished state.
In step 130, when the transporting device is in an idle state and the target put platform in the transporting task is in an idle state, the transporting task is allocated to the transporting device according to the priority of the task in the task list, so that the transporting device transports the cargo from the receiving platform to the target put platform according to the receiving platform identifier and the target put platform identifier.
In some embodiments, the carrying task further includes a task number, wherein when the carrying device arrives at the receiving station according to the receiving station identifier, the task number in the carrying task and the task number stored in the receiving station are verified, and if the verification is passed, a carrying instruction is sent to the carrying device, so that a task can be prevented from being received by mistake.
In some embodiments, the handling task further includes a task generation time, wherein the handling task is assigned to the handling equipment according to the priority of the task in the task list and the task generation time. For example, the task priority and the task generation time correspond to different weights, the task priority and the task generation time are weighted to obtain the priority corresponding to the receiving platform, and the task with the highest priority is distributed to the conveying equipment.
In the above embodiment, the upper control system and the bottom electronic control system perform a data interaction protocol to obtain the states of the receiving platform, the carrying equipment and the placing platform to generate the carrying task, and the reasonable issuing and execution of the task are realized by flexibly controlling the priority of the carrying task, so that the conveying efficiency of the goods is improved, and the phenomenon that the individual goods cannot be executed due to long-time waiting is avoided.
Fig. 2 is a flowchart illustrating a method for scheduling a transfer task according to another embodiment of the disclosure. In this embodiment, goods such as tobacco leaves, finished cigarettes, auxiliary materials and the like are placed in the tray, the carrying device is introduced by taking the shuttle as an example, and related information is set for the receiving platform, the placing platform and the shuttle in advance through the bottom device control system.
In step 210, it is monitored whether any tray arrives at the receiving station, if yes, step 220 is executed, otherwise, the waiting is continued.
In some embodiments, during the transfer of the pallet from the upstream process to the receiving station, the pallet may be monitored for arrival at the receiving station by an in situ photocell sensing device.
In some embodiments, the receiving and discharge stations are conventional link or roller conveyor equipment. As shown in fig. 3, a1, a2 and A3 in the warehouse are receiving platforms, B1, B2 and B3 are put platforms, the receiving platforms and the put platforms are located on two sides of the shuttle rail, and the shuttle runs in the rail.
At step 220, the pallet initiates a shuttle transport request.
In some embodiments, upon detecting that the cargo is transported to the pick-up station, the status of the pick-up station is set to be ready to perform a pick-up request task and the pick-up request is not responded to. For example, if the pallet arrives at a shuttle pick-up station, such as a1, the application bit at station a1 is marked 1, i.e., the station initiates a shuttle pick-up request, and the response bit is marked 0, i.e., the pick-up request is not responded to, and no shuttle transport task to be performed has been generated yet.
At step 230, a handling task is generated and the system continues to step 210.
In some embodiments, when detecting that a certain receiving station applies for the bit flag set 1 and responding to the bit flag set 0, the system acquires the station information, forms a carrying task to be executed, and writes the carrying task into a task list of the system. The carrying task information comprises a shuttle vehicle number, a task number, a receiving platform, a target platform, a task priority, a task generation time, a task state and the like, and the task initial state is not executed. If the task is successful, the application bit flag of the goods receiving platform is set to be 0, namely the platform does not initiate the goods receiving request of the shuttle car, and the response bit flag is set to be 1, namely the goods receiving request is responded.
In some embodiments, the tasks are prioritized according to the purpose of the receiving station.
At step 240, the shuttle vehicle initiates a task execution request.
In some embodiments, when the conveying equipment is in the idle state, the task flag bit of the conveying equipment is set to be in the accessible state, and the response flag bit is set to be in the task unallocated state. For example, when the shuttle is in an idle state, the shuttle initiates a task execution application, the application bit flag is set to 1, that is, the shuttle is idle, and can receive goods, and the response bit flag is set to 0, that is, the system has not allocated tasks to the shuttle.
At step 250, the shuttle car obtains the highest priority task from the list of tasks to be performed.
In some embodiments, the system issues the task to the shuttle car according to the task priority and the task generation time when the task target put platform is monitored to be idle.
In some embodiments, after the transporting equipment receives the transporting task, the task flag bit of the transporting equipment is set to the received state, and the response flag bit is set to the distributed task state. For example, the application bit flag of the shuttle is set to 0, i.e., the shuttle is already occupied and cannot receive new tasks. The response bit is marked 1, i.e. the system has assigned a task to the shuttle.
At step 260, the shuttle vehicle begins receiving goods.
In some embodiments, after the shuttle car receives the task, the starting device starts to execute the task, and the current task state is set as executing. When the shuttle vehicle arrives at the goods receiving station platform, the system compares and verifies the task number on the shuttle vehicle and the task number of the goods receiving station platform, and the goods receiving is allowed only if the task numbers are consistent, otherwise, the wrong goods receiving is possible, and the shuttle vehicle stops in front of the station platform to alarm and prompt manual intervention processing. And after the information is successfully verified, the shuttle car executes the goods receiving operation, and simultaneously the system clears the information of the task number, the tray number, the starting address, the target address and the like of the goods receiving station platform.
At step 270, the shuttle is put in stock.
In some embodiments, after the shuttle vehicle transports the pallet received from the origin station to the destination station, as in B1, the system writes the task information, e.g., task number, of the shuttle vehicle onto the destination station.
At step 280, the shuttle vehicle resumes an idle state.
In some embodiments, after the shuttle car is put in order, the information of the task number, the goods receiving platform and the target platform of the shuttle car is cleared, the application position flag is set to be 1, namely the shuttle car is idle and can receive goods, the response position flag is set to be 0, namely the system does not allocate the tasks to the shuttle car, and the current task is set to be in a 'finished' state.
In step 290, it is determined whether the shuttle vehicle has a transport task to be performed, if so, step 240 is performed, otherwise, step 280 is performed.
In some embodiments, there are multiple stations that successively initiate shuttle delivery applications, and thus, after a shuttle has completed a single task, it continues to determine whether the shuttle has a transport task yet to be performed.
In the embodiment, the task priority of each goods receiving platform is initialized or the priority of the unexecuted tasks is modified, the goods receiving sequence of the shuttle car is flexibly controlled, the task execution efficiency is improved, the long-time waiting phenomenon of individual tasks can be greatly avoided, and the operation efficiency of the warehouse is improved.
In addition, in the related technology, the whole scheduling process is in charge of bottom-layer electric control, and task data are not formed, so that the task tracing and analysis are not facilitated. In the embodiment, each carrying task can monitor the complete execution process to form a history record, thereby being beneficial to subsequent service backtracking.
In other embodiments of the present disclosure, the transporting task further includes a transporting apparatus number, wherein when the transporting apparatus corresponding to the transporting apparatus number fails, other transporting apparatuses are called.
In some embodiments, different shuttle vehicles are respectively responsible for the conveying task of the corresponding area, and when one shuttle vehicle fails, other shuttle vehicles can be informed to take over the conveying task of the area, so that the whole system can operate normally.
