BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the description of the embodiments of the present invention. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0017] Figure 1 is a flow chart of a production line intelligent scheduling method according to one embodiment of the present invention; Figure 2 It is a principle block diagram of an intelligent scheduling device for a production line in one embodiment of the present invention. DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] In one embodiment, if Figure 1 As shown, a production line intelligent scheduling method is provided, comprising the following steps: S10: When monitoring that a new scheduling task is put into the task pool or a scheduling task is adjusted, the task levels of all unexecuted scheduling tasks in the task pool, the equipment priorities of all equipment used by all unexecuted scheduling tasks, and the workpiece priorities of all workpieces required to be processed by all unexecuted scheduling tasks are obtained.

[0020] Understandably, the task pool refers to a database used to store and issue scheduling tasks. A new scheduling task refers to a scheduling task that is newly put into the task pool. Scheduling tasks refer to the planning and execution of processes such as workpiece processing. Unexecuted scheduling tasks refer to tasks that have not yet been issued for execution. The task level is used to characterize the criticality of the task. The equipment priority is used to characterize the priority of the equipment used for the unexecuted scheduling task. The workpiece priority is used to characterize the priority of the workpiece required to be processed for the unexecuted scheduling task. Among them, the task level, equipment priority and workpiece priority can use numerical values ​​to represent different levels. For example, the task level is 400, the equipment priority is 101 and the workpiece priority is 1000. Scheduling task adjustment refers to adjusting one or more of the task level, equipment priority or workpiece priority of the unexecuted scheduling tasks in the task pool.

[0021] Specifically, the task pool for scheduling tasks is monitored. If no new scheduling tasks are detected in the task pool or the task level / equipment priority / workpiece priority of unexecuted scheduling tasks in the task pool is adjusted, the task is issued and executed according to the current priority. If a new scheduling task is detected in the task pool or the task level / equipment priority / workpiece priority of unexecuted scheduling tasks in the task pool is adjusted, the relevant information of all unexecuted scheduling tasks in the task pool is obtained. Then, from all the relevant information, the task level of all unexecuted scheduling tasks, the equipment priority of all unexecuted scheduling tasks, and the workpiece priority of all workpieces required to be processed by all unexecuted scheduling tasks are extracted.

[0022] In another embodiment, a quantity threshold corresponding to the task pool is obtained. When the number of scheduled tasks in the task pool reaches the quantity threshold, the executed scheduled tasks are deleted and the records of the executed scheduled tasks are transferred to another database for storage and the data information is synchronized to the system to facilitate subsequent reference.

[0023] In another embodiment, the task pool only contains unexecuted scheduled tasks, and when a task in the task pool is issued, the task is deleted from the task pool. In this way, when it is detected that a new scheduled task is added to the task pool or the task level / equipment priority / workpiece priority of an unexecuted scheduled task in the task pool is adjusted, the relevant information of all scheduled tasks in the task pool is obtained, and the task level of all scheduled tasks, the equipment priority of all scheduled tasks, and the workpiece priority of all workpieces to be processed by all scheduled tasks are extracted from all relevant information.

[0024] S20: sorting all the unexecuted scheduled tasks by the task level, the device priority, and the workpiece priority corresponding to the same unexecuted scheduled task to obtain the task priority corresponding to each of the unexecuted scheduled tasks.

[0025] It can be understood that the task priority is used to represent the urgency of the unexecuted scheduled task, and a higher priority represents a more urgent task.

[0026] Specifically, the task priority corresponding to each unexecuted scheduling task is determined based on the task level, device priority and workpiece priority corresponding to the same unexecuted scheduling task, that is, the task level, device priority and workpiece priority corresponding to the same unexecuted scheduling task are obtained, and the weight of the task level, the weight of the device priority and the weight of the workpiece priority corresponding to the unexecuted scheduling task are queried and obtained. Then, the priority of the unexecuted scheduling task is processed by the weight of the task level and the task level, the weight of the device priority and the device priority, and the weight of the workpiece priority and the workpiece priority, so as to obtain the task priority corresponding to the unexecuted scheduling task. In this way, the priorities of all unexecuted scheduling tasks are calculated in the above manner to obtain the task priorities corresponding to each unexecuted scheduling task.

[0027] In one embodiment, task levels, device priorities, and workpiece priorities are quantified. For example, task levels are 3 for high, 2 for medium, and 1 for low; device priorities are 3 for high, 2 for medium, and 1 for low; and workpiece priorities are 3 for high, 2 for medium, and 1 for low. For an unscheduled task, assuming its task level is L, its device priority is E, and its workpiece priority is J, the task priority P can be calculated using the following formula: P = W1*L+W2*E+W3*J. For example, if W1 = 0.4, W2 = 0.3, and W3 = 0.3, the task level is high (L = 3), the device priority is medium (E = 2), and the workpiece priority is high (J = 3), then P = 0.4*3+0.3*2+0.3*3 = 2.7. This example is for illustration only and does not represent an actual setup.

[0028] In another embodiment, a hierarchical model is constructed, with task priority as the target layer, and task level, equipment priority, and workpiece priority as the criterion layer. A judgment matrix is ​​constructed through methods such as expert scoring. For example, regarding the relative importance between task level and equipment priority, experts judge based on experience that task level is slightly more important than equipment priority. In this case, the elements in the row corresponding to task level and the column corresponding to equipment priority in the judgment matrix can be set to 3 (indicating slightly important), and the elements in the row corresponding to equipment priority and the column corresponding to task level can be set to one-third. The weight vector of each criterion is calculated, and after a consistency check, a reasonable weight distribution is obtained. Then, based on the score of the task under each criterion (the quantification method is the same as the weighted comprehensive method), the task priority corresponding to each unexecuted scheduled task is calculated. This embodiment is for illustration only and does not represent the actual setting.

[0029] S30: Determine a target task queue according to all the task priorities, and issue and execute the scheduling task according to the target task queue.

[0030] Understandably, the target task queue refers to the task execution queue corresponding to all unexecuted scheduled tasks in the task pool. The task execution queue refers to the execution order of all unexecuted scheduled tasks.

[0031] Specifically, all unexecuted scheduled tasks are sorted according to their priorities. That is, all task priorities are compared using a bubble sort method to obtain a priority sorting result. Unexecuted scheduled tasks corresponding to each task priority are then sorted using the task priorities in the priority sorting result to obtain a target task queue. Scheduled tasks are then issued and executed based on the unexecuted scheduled tasks in the target task queue.

[0032] In one embodiment, if two or more unexecuted scheduled tasks have the same priority, the task level is used as the primary sorting criterion, the device priority is used as the secondary sorting criterion, and the workpiece priority is used as the third sorting criterion. If two unexecuted scheduled tasks are identical, a notification is sent to a preset administrator, who then determines the execution order.

[0033] The intelligent production line scheduling method of the present invention acquires the task level, device priority, and workpiece priority of all unscheduled tasks by adding a new scheduled task to the task pool or adjusting the task level, device priority, and workpiece priority of unscheduled tasks in the task pool. By determining the task level, device priority, and workpiece priority of the scheduled task, the priority of each unscheduled task is determined, so that the task priority reflects the urgency of each unscheduled task, thereby ensuring that urgent tasks are prioritized. This allows the production sequence to be adjusted according to production needs, thereby improving production efficiency.

[0034] In one embodiment, in step S20, determining the task priority corresponding to each of the unexecuted scheduled tasks based on the task level, the device priority, and the workpiece priority corresponding to the same unexecuted scheduled task includes: S201, obtaining information weights corresponding to respective target information; the target information includes task level, equipment priority, and workpiece priority.

[0035] S202 : Calculate the task priority corresponding to each of the unexecuted scheduled tasks according to the task level and its information weight, the device priority and its information weight, and the workpiece priority and its information weight.

[0036] It can be understood that the information weight refers to the weight corresponding to each target information, for example, 0.3, 0.2 or 0.4. The weight is set in advance and can be adjusted according to actual conditions.

[0037] Specifically, the information weight corresponding to each target information is retrieved from the task level, device priority, and workpiece priority in the target information, that is, a weight list is obtained. The information weight corresponding to the task level is retrieved from the weight list and determined as the level weight corresponding to the task level. Similarly, the information weight corresponding to the device priority is retrieved from the weight list and determined as the device weight corresponding to the device priority. Similarly, the information weight corresponding to the workpiece priority is retrieved from the weight list and determined as the workpiece weight corresponding to the workpiece priority. Further, based on the task level and its information weight, the device priority and its information weight, and the workpiece priority and its information weight, the task priority corresponding to each unexecuted scheduled task is calculated. Specifically, the task level, device priority, and workpiece priority corresponding to the same unexecuted scheduled task are obtained. The task level and its corresponding level weight, the device priority and its corresponding device weight, and the workpiece priority and its corresponding workpiece weight are then weighted to obtain the task priority corresponding to the unexecuted scheduled task. In this way, by calculating the priorities of all unexecuted scheduled tasks in the above manner, the task priorities corresponding to each of the unexecuted scheduled tasks can be obtained.

[0038] In this embodiment, by obtaining the information weight corresponding to each target information, the importance of different information is determined, and then the task priority is calculated, and the accuracy of the task priority in reflecting the importance of the task is ensured.

[0039] In one embodiment, in step S20, that is, sorting all the unexecuted scheduled tasks by the task level, the device priority, and the workpiece priority corresponding to the same unexecuted scheduled task to obtain the task priority corresponding to each of the unexecuted scheduled tasks, further comprising: S203: Obtain the waiting time required for all the unexecuted scheduled tasks.

[0040] S204 : Determine the task priority corresponding to each of the unexecuted scheduled tasks according to the task level, the device priority, the waiting time, and the workpiece priority corresponding to the same unexecuted scheduled task.

[0041] It can be understood that the waiting time refers to the length of time required to wait for executing the task, for example, 5 minutes or 15 minutes.

[0042] Specifically, when it is monitored that a new scheduling task is put into the task pool or the task level / equipment priority / workpiece priority is adjusted, in addition to obtaining the task level of all unexecuted scheduling tasks in the task pool, the equipment priority of the equipment used, and the workpiece priority of the workpiece to be processed, the waiting time required for all unexecuted scheduling tasks is also obtained, that is, the relevant information corresponding to each unexecuted scheduling task is obtained, and then the task level, equipment priority, workpiece priority and waiting time corresponding to the priority are extracted from the relevant information. Furthermore, the task priority corresponding to each unexecuted scheduling task is determined based on the task level, device priority, waiting time and workpiece priority corresponding to the same unexecuted scheduling task, that is, the level weight corresponding to the task level, the device weight corresponding to the device priority, the workpiece weight corresponding to the workpiece priority and the time weight corresponding to the waiting time are queried and obtained, and the task level, device priority, waiting time and workpiece priority corresponding to the same unexecuted scheduling task, and their level weight, device weight, time weight and workpiece weight are weighted, that is, the task level is multiplied by the level weight, the device weight is multiplied by the device priority, the waiting time is multiplied by the time weight and the workpiece priority is multiplied by the workpiece weight, and all the multiplication results are summed up to obtain the task priority corresponding to the unexecuted scheduling task. In this way, by calculating the priorities of all unexecuted scheduling tasks in the above manner, the task priorities corresponding to each unexecuted scheduling task can be obtained.

[0043] In this embodiment, the importance of different information is determined through task level and level weight, device priority and device weight, waiting time and time weight, and workpiece priority and workpiece weight, thereby realizing the calculation of task priority, and thus the task priority can accurately reflect the importance of the scheduled task.

[0044] In one embodiment, in step S204, determining the task priority corresponding to each of the unexecuted scheduled tasks based on the task level, the device priority, the waiting time, and the workpiece priority corresponding to the same unexecuted scheduled task includes: S2041: Obtain a time threshold, and compare the time threshold with the waiting time corresponding to each of the unexecuted scheduled tasks.

[0045] S2042: If the waiting time exceeds the time threshold, obtain an adjustment parameter corresponding to the time threshold, and adjust the waiting time of the unexecuted scheduled task according to the adjustment parameter to obtain an adjusted waiting time.

[0046] S2043 : Determine the task priority corresponding to each of the unexecuted scheduled tasks according to the task level and its weight, the device priority and its weight, the adjustment waiting time and its weight, and the workpiece priority and its weight.

[0047] It is understood that the time threshold refers to the threshold used to evaluate the waiting time, for example, 3 minutes. The adjustment parameter refers to the value used to adjust the waiting time of the scheduled task, for example, 5 minutes. The adjusted waiting time refers to the waiting time after the adjustment.

[0048] Specifically, after obtaining the waiting time, a time threshold is obtained, and the waiting time corresponding to each unexecuted scheduled task is compared with the time threshold. If the waiting time does not exceed the time threshold, the waiting time of the unexecuted scheduled task is not adjusted. If the waiting time exceeds the time threshold, an adjustment parameter corresponding to the time threshold is obtained, and the waiting time of the unexecuted scheduled task is adjusted by the adjustment parameter, that is, the waiting time and the adjustment parameter are differenced, and it is determined whether the difference is greater than or equal to zero. When the difference is less than zero, zero is determined as the adjusted waiting time. When the difference is greater than or equal to zero, the difference is determined as the adjusted waiting time. In this way, the adjusted waiting time corresponding to each unexecuted scheduled task can be obtained. Furthermore, according to the task level and its weight, the device priority and its weight, the adjustment waiting time and its weight, and the workpiece priority and its weight, the task priority corresponding to each unexecuted scheduling task is determined, that is, the level weight corresponding to the task level, the device weight corresponding to the device priority, the workpiece weight corresponding to the workpiece priority, and the time weight corresponding to the adjustment waiting time are obtained, and the task level and its level weight, the device priority and its device weight, the adjustment waiting time and its workpiece weight, and the workpiece priority and its time weight corresponding to the same unexecuted scheduling task are weighted, and the task priority corresponding to the unexecuted scheduling task can be obtained. In this way, by calculating the priorities of all unexecuted scheduling tasks in the above manner, the task priority corresponding to each unexecuted scheduling task can be obtained.

[0049] In this embodiment, the importance of different information is determined through task level and its weight, device priority and its weight, adjustment waiting time and its weight, and workpiece priority and its weight, thereby realizing the calculation of task priority, and thus the task priority can accurately reflect the importance of the task.

[0050] In one embodiment, in step S20, determining the task priority corresponding to each of the unexecuted scheduled tasks based on the task level, the device priority, and the workpiece priority corresponding to the same unexecuted scheduled task, further includes: S205 : Acquire all task artifacts corresponding to the unexecuted scheduled tasks and the first priorities corresponding to the task artifacts, as well as all task devices and the second priorities corresponding to the task devices.

[0051] S206: Compare all the first priorities and select the first priority with the highest priority to be determined as the workpiece priority; and compare all the second priorities and select the second priority with the highest priority to be determined as the device priority.

[0052] S207 , inputting the task level, the device priority, and the workpiece priority corresponding to the same unexecuted scheduled task into a preset task model, and outputting the task priority corresponding to each unexecuted scheduled task.

[0053] Understandably, the first priority refers to the priority associated with each task artifact. A task artifact refers to the artifact required for processing in each unscheduled task. The second priority refers to the priority associated with each task device. A task device refers to the device used to execute the unscheduled task. The preset task model refers to a neural network model trained with a large amount of sample data and used to calculate task priorities.

[0054] Specifically, when there are multiple task devices and task artifacts in an unexecuted scheduled task, all task artifacts corresponding to the unexecuted scheduled task and the first priority corresponding to each task artifact, as well as all task devices and the second priority corresponding to each task device are obtained. That is, relevant information corresponding to the unexecuted scheduled task is obtained, and all task artifacts and the first priority corresponding to each task artifact, as well as all task devices and the second priority corresponding to each task device are extracted from the relevant information. Then, all first priorities are compared, and the first priority with the highest priority is screened out, and the first priority is determined as the artifact priority. Similarly, all second priorities are compared, and the second priority with the highest priority is screened out, and the second priority is determined as the device priority. Next, obtain the preset task model, and input the task level, equipment priority and workpiece priority corresponding to the same unexecuted scheduling task into the preset task model. The task priority is calculated for the task level, equipment priority and workpiece priority through the priority calculation formula learned during the training of the preset task model. That is, the task level, equipment priority and workpiece priority are weighted by the weight parameters learned during training, and the task priority corresponding to each of the unexecuted scheduling tasks output by the preset task model can be obtained.

[0055] In another embodiment, the task level, device priority, and workpiece priority corresponding to the same unexecuted scheduled task are obtained, and then the task level and its corresponding weight, the device priority and its corresponding weight, and the workpiece priority and its corresponding weight are weighted to obtain the task priority corresponding to the unexecuted scheduled task. In this way, by calculating the priorities of all unexecuted scheduled tasks in the above manner, the task priority corresponding to each unexecuted scheduled task can be obtained.

[0056] In this embodiment, by comparing the first priorities of all task artifacts and the second priorities of all task devices, the artifact priorities and device priorities are screened, thereby realizing the calculation of all task priorities, thereby ensuring the accuracy of the priorities of unexecuted scheduled tasks and reflecting the urgency of unexecuted scheduled tasks.

[0057] In one embodiment, in step S30, determining a target task queue according to all the task priorities, and issuing and executing the scheduled task according to the target task queue includes: S301 , sorting all the unexecuted scheduled tasks according to the priorities of all the tasks to obtain a target task queue.

[0058] S302: Distribute and execute the unexecuted scheduled tasks in the target task queue.

[0059] Specifically, after obtaining the task priority, all task priorities are compared and sorted according to the size of the task priority, thereby obtaining a priority sorting result. Then, all unexecuted scheduled tasks are sorted according to the task priority in the priority sorting result, that is, the unexecuted scheduled tasks are sorted according to the position of the task priority in the priority sorting result, and the target task queue can be obtained. Next, tasks are issued and executed according to the target task queue, that is, when the previous scheduled task is completed, the unexecuted scheduled task with the highest task priority in the target task queue is issued, that is, the first unexecuted scheduled task in the target task queue is issued, and the unexecuted scheduled task is executed.

[0060] In this embodiment, all scheduled tasks are sorted by task priority, thereby obtaining the target task queue, facilitating the subsequent issuance and execution of scheduled tasks, and further enabling priority processing of urgent tasks.

[0061] In one embodiment, before step S30, that is, before issuing and executing the unexecuted scheduled tasks in the target task queue, the process further includes: S40, when it is monitored that the number of unexecuted scheduled tasks in the task pool changes or the scheduled tasks are adjusted, the task levels of all unexecuted scheduled tasks in the task pool, the equipment priorities of all equipment used by the unexecuted scheduled tasks, and the workpiece priorities of the workpieces required to be processed by all unexecuted scheduled tasks are obtained.

[0062] S50 , determining an update priority corresponding to each of the unexecuted scheduled tasks according to the task level, the device priority, and the workpiece priority corresponding to the same unexecuted scheduled task.

[0063] S60 , issuing and executing tasks according to the updated priorities corresponding to the unexecuted scheduled tasks in the updated task queue, wherein the updated task queue refers to the updated task execution queue corresponding to all unexecuted scheduled tasks in the task pool.

[0064] Understandably, updating the priority refers to recalculating the result of all unexecuted scheduled tasks. Updating the task queue refers to the updated task execution queue corresponding to all unexecuted scheduled tasks in the task pool.

[0065] Specifically, the unexecuted scheduled tasks in the task pool are monitored in real time. When the number of unexecuted scheduled tasks in the task pool is monitored to change or the scheduled tasks are adjusted, that is, when the scheduled tasks are monitored to be put into the task pool, or when the task level / equipment priority / workpiece priority of the unexecuted scheduled tasks in the task pool is adjusted, the task level of all unexecuted scheduled tasks in the task pool, the equipment priority of all equipment used by the unexecuted scheduled tasks, and the workpiece priority of all workpieces required to be processed by the unexecuted scheduled tasks are obtained. Then, based on the task level, equipment priority, and workpiece priority corresponding to the same unexecuted scheduled task, the update priority corresponding to each unexecuted scheduled task is determined. That is, the task level, equipment priority, and workpiece priority corresponding to the same unexecuted scheduled task are obtained, and the weight of the task level, the weight of the equipment priority, and the weight of the workpiece priority corresponding to the unexecuted scheduled task are queried and obtained. Then, the weight of the task level is weighted with the task level, the weight of the equipment priority is weighted with the equipment priority, and the weight of the workpiece priority is weighted with the workpiece priority to obtain the update priority corresponding to each unexecuted scheduled task. Next, all unexecuted scheduled tasks are sorted according to their update priorities. This involves first comparing all update priorities and then sorting them based on the comparison results to obtain an update priority sorting result. This sorting process then creates an update task queue. Unexecuted scheduled tasks in the update task queue are dispatched and executed in the order they appear.

[0066] In this embodiment, by monitoring the task pool, real-time updating of the priorities of all scheduled tasks is achieved, and the production order is adjusted according to production needs, thereby ensuring priority processing of urgent tasks, ensuring the accuracy of priorities, reflecting the emergency procedures of all scheduled tasks, and thus improving production efficiency.

[0067] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0068] In one embodiment, a production line intelligent scheduling device is provided, which corresponds one-to-one to the production line intelligent scheduling method in the above embodiment. Figure 2 As shown, the production line intelligent scheduling device includes a priority acquisition module 10, a priority determination module 20 and a scheduling task execution module 30. The functional modules are described in detail as follows: The priority acquisition module 10 is used to acquire the task levels of all unscheduled tasks in the task pool, the equipment priorities of all equipment used by all unscheduled tasks, and the workpiece priorities of all workpieces required to be processed by all unscheduled tasks when a new scheduled task is added to the task pool or a scheduled task is adjusted; The priority determination module 20 is configured to input the task level, the equipment priority, and the workpiece priority corresponding to the same unexecuted scheduled task into a preset task model, and output the task priority corresponding to each unexecuted scheduled task; The scheduling task execution module 30 is used to determine a target task queue according to all the task priorities, and to issue and execute the scheduling task according to the target task queue.
