Fig. 1 is a flow diagram of some embodiments of a method of scheduling a handling task of the present disclosure. This embodiment is performed by an upper control system.
In step 110, the status of the receiving station, the handling equipment and the placing station is obtained.
In some embodiments, it is monitored in real time whether there is cargo being transported to the receiving station, whether the handling equipment is idle, and whether the delivery station is idle.
In some embodiments, the relevant information is stored at the pick-up station, the handling equipment, and the pick-up station, respectively, by an underlying equipment control system, such as a PLC. For example, the receiving station information includes a station identification, a task number, a starting station, a destination station identification, an application bit flag, and a response bit flag. The loading dock information includes a dock identification and a task number. The station identifier is, for example, a station number, the starting station is the receiving address of the handling equipment, and the destination station is the placing address of the handling equipment.
The handling equipment information comprises equipment identification, task number, cargo number, starting station, target station, application bit mark and response bit mark. The handling device is for example a shuttle and the device identification is for example a device number.
In some embodiments, it is detected by a photocell sensing device whether the cargo is being transported to the receiving station.
In step 120, when the status of the receiving station is that the receiving request task is to be executed, a transporting task of the receiving station is formed, and the transporting task is written into the task list, wherein the transporting task includes a task priority, a receiving station identifier and a target loading station identifier.
In some embodiments, the handling task further includes a task state, wherein the task state is an unexecuted state when the handling task is formed; when a transport task is assigned to transport equipment, the task state is an executing state; and after the handling equipment transports the goods from the goods receiving station to the destination goods placing station, the task state is a finished state.
In step 130, when the handling device is in an idle state and the target loading platform in the handling task is in an idle state, the handling task is allocated to the handling device according to the priority of the task in the task list, so that the handling device transports the goods from the loading platform to the target loading platform according to the receiving platform identifier and the target loading platform identifier.
In some embodiments, the handling task further includes a task number, where when the handling device arrives at the receiving station according to the receiving station identifier, the task number in the handling task and the task number stored in the receiving station are checked, and if the checking is passed, a handling instruction is sent to the handling device, so that the task with a wrong receiving task can be avoided.
In some embodiments, the handling task further includes a task generation time, wherein the handling task is allocated to the handling device 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 and calculated to obtain the priority corresponding to the receiving platform, and then the task with the highest priority is distributed to the carrying equipment.
In the above embodiment, the upper control system and the bottom electric control system perform a data interaction protocol to obtain the states of the receiving platform, the transporting device and the placing platform so as to generate the transporting task, and the priority of the transporting task is flexibly controlled to realize the reasonable issuing and execution of the task, thereby improving the transporting efficiency of the goods and avoiding the phenomenon that individual goods wait for a long time and cannot be executed.
Fig. 2 is a flow chart illustrating further embodiments of a method for scheduling a handling task according to the present disclosure. In this embodiment, the goods such as tobacco leaves, finished cigarettes, auxiliary materials and the like are placed in the tray, the handling equipment is introduced by taking the shuttle as an example, and related information is set for the receiving station, the placing station and the shuttle in advance through the bottom equipment control system.
In step 210, it is monitored whether a pallet arrives at the receiving station, if yes, step 220 is executed, otherwise, waiting is continued.
In some embodiments, during the transfer of the pallet from the upstream process to the receiving station, the presence of the pallet at the receiving station may be monitored by an in situ photocell sensing device.
In some embodiments, the pick-up and drop-out stations are conventional chain or roller conveyor apparatuses. As shown in fig. 3, A1, A2, A3 in the warehouse are receiving stations, B1, B2, B3 are placing stations, the receiving stations and the placing stations are located at two sides of a shuttle rail, and the shuttle runs in the rail.
At step 220, the pallet initiates a shuttle handling request.
In some embodiments, the status of the receiving station is set to be ready to perform the receiving request task when the goods are detected to be transported to the receiving station, and the receiving request is not responded to. For example, if the pallet arrives at the shuttle receiving platform, such as A1, the application position of the A1 platform is marked with 1, that is, the platform initiates the shuttle receiving request, and the response position is marked with 0, that is, the receiving request is not responded, and the shuttle carrying task to be executed is not generated yet.
At step 230, a transport task is generated and the system continues to step 210.
In some embodiments, when a certain receiving station applies for the position flag 1 and responds to the position flag 0, the system acquires the station information to form a transport task to be executed, and writes the transport task into a task list of the system. The handling task information comprises a shuttle number, a task number, a receiving platform, a target platform, a task priority, task generation time, a task state and the like, and the initial state of the task is not executed. If the task is successful, the application bit flag of the receiving platform is set to 0, namely the platform does not initiate the shuttle vehicle receiving request, and the response bit flag is set to 1, namely the receiving request is responded.
In some embodiments, the tasks are prioritized according to the use of the receiving platform.
At step 240, the shuttle initiates a task execution request.
In some embodiments, the task flag of the handling device is set to the pickable state when the handling device is in the idle state, and the response flag is set to the unassigned task state. For example, when the shuttle is in an idle state, the shuttle initiates a task execution application, applies for position flag 1, i.e., the shuttle is idle, available for pickup, and responds to position flag 0, i.e., the system has not yet assigned a task to the shuttle.
In step 250, the shuttle obtains the highest priority task from the list of tasks to be performed.
In some embodiments, the system issues the task to the shuttle according to the task priority and the task generation time if it is monitored that the task target delivery station is idle.
In some embodiments, after the handling device receives the handling task, the task flag of the handling device is set to the picked-up state and the response flag is set to the assigned task state. For example, the application position of the shuttle is marked 0, i.e. the shuttle is already occupied, and no new task can be received. The response bit is set to 1, i.e., the system has assigned a task to the shuttle.
At step 260, the shuttle starts receiving cargo.
In some embodiments, after the shuttle receives the task, the starting device starts to execute the task, and the current task state is set as executing. When arriving at the receiving station platform, the system can compare and check the task number on the shuttle vehicle with the task number of the receiving station platform, and only the receiving is allowed if the task number is consistent with the task number of the receiving station platform, otherwise, the condition that the receiving error is possible is indicated, and the shuttle vehicle stops at the station platform, and then the system alarms to prompt manual intervention processing. And after the information is successfully checked, the shuttle vehicle executes the goods receiving operation, and simultaneously the system clears the information such as the task number, the tray number, the starting address, the target address and the like of the goods receiving station.
At step 270, the shuttle is put in stock.
In some embodiments, after the shuttle has transported the pallet from the starting station to the destination station, as in B1, the system writes the task information of the shuttle, e.g., the task number, to the destination station.
At step 280, the shuttle resumes an idle state.
In some embodiments, after the delivery of the shuttle is completed, the task number, the delivery station and the destination station information of the shuttle are cleared, the application position flag 1 is set, that is, the shuttle is idle, the delivery can be carried out, and the response position flag 0 is set, that is, the system does not assign a task to the shuttle yet, and the current task is set to be in a 'completed' state.
In step 290, it is determined whether the shuttle has a transport task to be executed, if so, step 240 is executed, otherwise, step 280 is executed.
In some embodiments, there are multiple stations that successively initiate a shuttle delivery application, and thus, after the shuttle has completed a single task, continue to determine whether the shuttle has more of a transport task to be performed.
In the embodiment, the receiving sequence of the shuttle is flexibly controlled by initializing the task priority of each receiving station or modifying the priority of the unexecuted task, so that the task execution efficiency is improved, the long-time waiting phenomenon of individual tasks can be avoided to a great extent, and the operation efficiency of the warehouse is improved.
In addition, in the related technology, the whole scheduling process is in charge of bottom electric control, task data are not formed, and the task tracing and analysis are not facilitated. In this embodiment, each handling task can monitor the complete execution process to form a history record, which is beneficial to subsequent business backtracking.
In other embodiments of the present disclosure, the handling task further includes a handling device number, where when a handling device corresponding to the handling device number fails, other handling devices are called.
In some embodiments, different shuttles are respectively responsible for the transport tasks of the corresponding areas, and when one of the shuttles fails, other shuttles can be notified to take over the transport tasks of the corresponding areas, so that the whole system can normally operate.
