Description

Technical Field

[0001] This application relates to the field of magnetic drive technology, and particularly to a method, device, computer device, computer-readable storage medium, and computer program product for restoring the mover numbering. Background Art

[0002] On a magnetic drive conveyor line, the structure of a mover (also known as a trolley) is mainly composed of permanent magnet plates and has no circuit structure. Therefore, all the numbering sources of the system trolleys are obtained by the driver feeding back the positions of the trolleys on the current track, and the system sequentially assigns trolley numbers according to the current positions.

[0003] In a logistics line that combines magnetic drive and belt, since there is no driver on the belt line, it is impossible to obtain the current trolley system numbering information, and at the same time, the trolley has no physical number. Therefore, after leaving the belt line, the current system numbering information may be lost due to power failure or system errors, resulting in abnormal operation of the magnetic drive conveyor line.

Obviously, the drawings in the following description are only some embodiments of the present application.

[0037] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] The mover number restoration method provided by the embodiments of the present application can be applied to a Figure 1 magnetic drive system as shown. The magnetic drive system includes a magnetic drive conveyor line, a mover running on the magnetic drive conveyor line, and a control system. The magnetic drive conveyor line can be a hybrid conveyor line or a pure magnetic drive line. The hybrid conveyor line includes a magnetic drive section and a belt section, and the pure magnetic drive line only includes a magnetic drive section. The magnetic drive section includes a driver, and the driver can obtain the position of the mover, so that the control system can generate the number of the mover based on the position of the mover.

[0039] For the hybrid conveyor line, when the mover moves to the belt section, the current system number information may be lost due to power failure or system error. For example, the data backed up at the previous time point is generally used for restoration. However, in the hybrid magnetic drive line, since the mover cannot be located on the belt line without auxiliary positioning devices such as drivers, when a mover runs onto the belt line, the backed-up data at this time is incomplete, and the number of backed-up movers may be less than the actual number of movers.

[0040] For the pure magnetic drive line, during the movement of the mover, the number may also be lost due to reasons such as power failure. At this time, the number data of the previous mover recorded by the magnetic drive line is generally used for a certain restoration work. However, when using the number data of the previous mover recorded by the magnetic drive line for restoration currently, if the data backed up before the power failure is problematic, the restored number data of the mover is also problematic.

[0041] To solve the above problems and accurately restore the mover number, in the present application, the backup data of the mover number corresponding to each backup time point is first obtained; then the backup data of the mover number at each backup time point is identified to determine the target valid backup data; and the mover numbers of each mover are restored based on the target valid backup data. In this way, the backup data is first identified to determine the accurate backup data, and then the mover number is restored based on the accurate backup data, which improves the accuracy of the mover number.

[0042] In an exemplary embodiment, as Figure 2 shown, a mover number restoration method is provided. Taking the control system in Figure 1 as an example, the method includes the following steps S202 to S206. Among them:

[0043] S202: Obtain the backup data of the mover numbers corresponding to each backup time.

[0044] The backup data of the mover numbers includes the backup time, the mover number, and the mover position.

[0045] The mover number is obtained based on the mover position. The mover position can be represented by mover coordinates. The mover coordinates are mapped with respect to a preset origin according to the road section where the mover is located and the position of the mover on the road section to obtain three-dimensional coordinates. In the traditional solution, the mover coordinates only consider one-dimensional coordinates and road section information, which not only has less information but also has low robustness. In this embodiment, it can adapt to ordinary straight sections (one-dimensional (x)), fork roads, circular lines (two-dimensional (xy)), and multi-layer logistics lines in three-dimensional space (xyz). At the same time, it can also be abstracted into a two-dimensional topology of xy (z = 0) to implement subsequent calculations.

[0046] S204: Identify the backup data of the mover numbers at each backup time to determine the target valid backup data.

[0047] The valid backup data is the correct backup data. By identifying the backup data of the mover numbers at each backup time, the valid backup data is obtained.

[0048] The target refers to the backup time closest to the current time, so as to ensure that the target valid backup data is the latest and correct backup data.

[0049] Identifying the backup data of the mover numbers at each backup time can be based on a preset logic. Combining the scenario of this embodiment, when a mover runs onto the belt section, the backup data at this time is incomplete, and the number of backup movers is less than the actual number of movers. Therefore, the preset logic can be generated based on the number of movers. The preset identification logic can be to judge whether the number of movers has changed. If it has changed, it means the data is invalid.

[0050] In one optional embodiment, the backup data of the mover numbers at each backup time is identified to determine the target valid backup data, including: determining the current backup time, and comparing the backup data corresponding to the current backup time with the backup data corresponding to the previous backup time to obtain a comparison result; in the case where the comparison result indicates that the backup data corresponding to the current backup time is consistent with the backup data corresponding to the previous backup time, taking the previous backup time as the current backup time, and continuing to execute the step of comparing the backup data corresponding to the current backup time with the backup data corresponding to the previous backup time to obtain a comparison result until the comparison result indicates that the backup data corresponding to the current backup time is inconsistent with the backup data corresponding to the previous backup time, and taking the backup data corresponding to the current backup time as the target valid backup data.

[0051] Combined with Figure 3 as shown in Figure 3 FIG. is a schematic diagram of the backup logic in an embodiment. In this embodiment, n is the current backup time. Starting from the n backup time, it is determined whether the number of movers has mutated. For example, the number of movers in the backup data corresponding to the n backup time is compared with the number of movers in the backup data corresponding to the n - 1 backup time. If the comparison result indicates that the backup data corresponding to the current backup time is consistent with the backup data corresponding to the previous backup time, then taking the n - 1 backup time as the current backup time, and continuing to compare the number of movers in the backup data corresponding to the n - 1 backup time with the number of movers in the backup data corresponding to the n - 2 backup time until the comparison result indicates that the backup data corresponding to the current backup time is inconsistent with the backup data corresponding to the previous backup time, and taking the backup data corresponding to the current backup time as the target valid backup data.

[0052] Among them, the judgment of whether the backup data corresponding to the current backup time is consistent with the backup data corresponding to the previous backup time can be to determine whether there is a mutation in the number of movers corresponding to the current backup data compared with the number of movers corresponding to the previous backup data. Wherein the current backup data is the backup data corresponding to the current backup time, and the previous backup data is the backup data corresponding to the previous backup time.

[0053] Specifically, starting from the n moment, it is determined whether there is a quantity mutation; if there is no quantity mutation, it is determined that the backup data at the n moment is valid and is the target valid backup data; if there is a quantity mutation, it is traced back sequentially from the n - 1 moment until the moment when the quantity has not mutated for the last time stops. Figure 3 In the figure, the backup data with the correct quantity is found by tracing back to the n - 5 moment. The n - 5 moment is the correct time point, and the corresponding backup data is the target valid backup data. After determining the correct time point and the correct target valid backup data, the backup logic ends.

[0054] Another point that needs to be explained is that the number of backup times traced back by the backup logic can be less than a preset number, so as to avoid errors caused by the change in the number of movers over a long time. The value range of the preset number is 5 to 10, including the boundary values. In other embodiments, the value range of the preset number can also be other values, which are not specifically limited herein.

[0055] In the above embodiments, by comparing the number of mover numbers backed up at each time, the time when the backed-up mover numbers are correct can be determined, and then the target valid backup data can be determined. In this way, the obtained target valid backup data can be accurate, and the effectiveness of the target valid backup data can be improved.

[0056] S206: Restore the mover numbers of each mover based on the target valid backup data.

[0057] Among them, when the target valid backup data is correct, the mover numbers of the movers can be restored based on the mover positions of each mover in the valid backup data.

[0058] For example, if the target valid backup data carries the mover positions, each mover can also obtain the corresponding mover position based on the driver in the magnetic drive segment. In this way, based on the mover positions, the matching relationship between the actual movers and the movers in the target valid backup data can be determined, and then the mover numbers of the matching movers can be obtained.

[0059] In the above mover number restoration method, the backup data corresponding to each backup time is obtained; the backup data of the mover numbers at each backup time is identified to determine the target valid backup data; the mover numbers of each mover are restored based on the target valid backup data. In this way, the backup data is first identified to determine the accurate backup data, and then the mover numbers are restored based on the accurate backup data, improving the accuracy of the mover numbers.

[0060] In one alternative embodiment, as shown in Figure 4 shown, Figure 4 is a flowchart of the mover number restoration steps in an embodiment. The mover number restoration steps, that is, restoring the mover numbers of each mover based on the target valid backup data, include:

[0061] S402: Randomly number each mover at the current time to obtain each random number group, and each random number group includes the numbers corresponding to each mover.

[0062] Among them, randomly numbering each mover at the current time to obtain each random number group is the initialization process at the current time, that is, after a power failure recovery or other situations, the numbers of each mover are initialized, and the initialization process is a process of randomly numbering the movers.

[0063] In one alternative embodiment, each mover is randomly numbered at the current moment to obtain respective random number groups, including: obtaining the positions of each mover at the current moment and generating random number groups based on the positions of each mover.

[0064] Specifically, at the current moment, for example, at the nth moment, the coordinate information of each mover is obtained, and then the movers are randomly numbered based on this coordinate information to obtain multiple random number groups.

[0065] Each random number group includes the mover numbers and the mover positions, and the corresponding mover numbers in each random number group are all different.

[0066] S404: Match each random number group with the target valid backup data.

[0067] S406: Based on the random number groups that match successfully with the target valid backup data, obtain the mover numbers of each mover at the current moment.

[0068] The target valid backup data includes mover numbers and mover positions. In this way, the mover numbers and mover positions in the random number groups are matched with the mover numbers and mover positions in the target valid backup data to obtain a matching result.

[0069] In one alternative embodiment, matching each random number group with the target valid backup data includes: based on the correspondence between the random numbers in each random number group and the mover numbers of each mover in the target valid backup data, calculating the correlation between the positions of each mover in the random number group and the positions of each mover in the target valid backup data to obtain the correlation; determining the random number groups with the correlation meeting the requirements as the random number groups that match successfully with the target valid backup data.

[0070] Among them, according to the correspondence between the random numbers in each random number group and the mover numbers of each mover in the target valid backup data, the positions of the movers with the corresponding numbers are matched, for example, calculating the correlation. Specifically, the correlation can be calculated respectively for the mover coordinates, for example, calculating the correlation between the two for the XYZ coordinates.

[0071] Optionally, the correlation can be a correlation analysis based on covariance. In other embodiments, the correlation can be other representation methods, which are not specifically limited herein.

[0072] After obtaining the correlations between each random number group and the target valid backup data, the random number groups with the correlation meeting the requirements can be selected as the random number groups that match successfully with the target valid backup data, and the successfully matched random number groups are used as the backup data at the current moment.

[0073] Among them, the correlation meeting the requirements can be to select the group of random number groups with the largest correlation, and use this group of random number groups as the correct number of the mover at the current moment.

[0074] In the above embodiments, the current recovery algorithm is improved. On the one hand, by comparing the number of backup mover numbers at each moment, the effective target effective backup data is determined, thereby reducing the error of the backup data and making the obtained target effective backup data accurate. On the other hand, by calculating the correlation between the target effective backup data and the random number groups obtained from the random numbers, the accurate random number groups with the correlation meeting the requirements are determined. In this way, the accuracy of the mover number recovery is improved by calculating the correlation and performing number recovery based on the target effective backup data.

[0075] It should be understood that although the steps in the flowcharts involved in the above embodiments are sequentially shown according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same moment, but can be executed at different moments. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least a part of other steps or steps or stages in other steps.
