[0019] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Existing data interpolation algorithms only interpolate a single device and do not consider the collaborative relationship between devices. The KNN (K-Nearest Neighbor) interpolation algorithm can perform data interpolation based on the similarity of data and has a certain ability to capture the collaborative effect between devices.

[0022] When using the KNN algorithm for data interpolation, since the original data, that is, some working data of the device, is missing and the distance between samples cannot be directly calculated, the KNN distance matrix cannot be formed, and thus the missing data needs to be temporarily filled first. For time series data such as the working data of the device, usually only the previous or the next data of the missing data is used to fill the missing data to form a complete data set.

[0023] However, when calculating the distance between samples, it is affected by the temporarily filled data. Using the previous or next data of the missing data to fill the missing item only considers the working data of a single device and does not consider the collaborative similarity between devices. For example, if the missing data of a certain device is abnormal current data and other devices have collected this abnormal current data, if it is filled only according to the previous or next data of this device, a large error will be obtained when calculating the distance matrix using the filled working data, and thus there will also be a large error in the final interpolation result.

[0024] To solve the above problems, the present invention provides a device collaborative scheduling method, device, equipment and medium based on the industrial Internet of Things. The following is a detailed introduction to the solution of the present invention.

[0025] Figure 1 As shown in the flowchart of the device collaborative scheduling method based on the industrial Internet of Things according to an embodiment of the present invention, the device collaborative scheduling method based on the industrial Internet of Things can be executed by a device collaborative scheduling device with data processing capabilities. The device collaborative scheduling device can be a device collaborative scheduling device based on the industrial Internet of Things. Referring to Figure 1 FIG., the device collaborative scheduling method based on the industrial Internet of Things may include the following steps: Step S1, obtain the working data sequences of various categories of each device.

[0026] Among them, the working data sequence is a time-series data sequence representing the working state of the device.

[0027] In a specific implementation process, the working data sequences of various categories of each device can be obtained from an object platform storing various data of the device. The working data sequences of various categories of each device can be the load data, current data, voltage data, energy consumption data, task execution time data, etc. of the device. It should be noted that the load data can be collected through sensors or device monitoring tools on the device; the current data and voltage data can be collected through sensors or smart meters on the device; the energy consumption data can be collected through energy consumption monitoring devices or smart meters on the device; the task execution time data can be obtained from the object platform.

[0028] Step S2, determine a number of target sequences based on the working data sequences of the same category of each device and perform interpolation on each target sequence, where the target sequence is a working data sequence missing several data.

[0029] It should be noted that when using common interpolation algorithms such as linear interpolation algorithm, spline interpolation algorithm, polynomial interpolation algorithm, etc. to interpolate the working data sequence of a device, only the working data sequence of a single device is considered, that is, the collaborative relationship between devices is not considered. The KNN (K-Nearest Neighbors) algorithm can perform data interpolation based on the similarity of data. Therefore, in this embodiment, the KNN algorithm is used to interpolate the device. However, when calculating the distance matrix using the KNN interpolation algorithm, the missing data needs to be filled first. In the existing algorithms, only the previous data or the next data of the missing data is used to fill the missing item, and the similarity and collaborative relationship between devices are not considered.

[0030] Based on this, in the embodiment of the present invention, based on the similarity and collaborative relationship between devices, the working data sequence of the device with missing data is interpolated by using the working data sequences of the devices with non-missing data. Considering that in the same working workshop, multiple devices work simultaneously, and at this time, the environmental conditions and sensor configurations of multiple devices are similar. The working data sequences of the devices with non-missing data can often better reflect the working state of the device represented by the missing data. Therefore, the working data sequences of the devices with non-missing data can better provide interpolation references for the devices with missing data.

[0031] In this embodiment, an example of any category of working data sequence is used for illustration. It can be understood that due to the collaborative relationship between devices, for different devices, there is a certain correlation in the working data sequences of the same category. For example, if there are some missing data in the current data sequence of a certain device, the data in the current data sequence of other devices can be used to temporarily fill the missing data of this device. Therefore, compared with only relying on other data in the current data sequence of this device for temporary filling, by introducing the current data sequences of other devices, the similarity and collaborative relationship between devices can be combined, and the accuracy of temporarily filling the missing data can be significantly improved.

[0032] In one embodiment, in step S2, determining a plurality of target sequences based on the working data sequences of the same category of each device and interpolating each target sequence may specifically include: S21. Determine a plurality of target sequences from the working data sequences of the same category of each device, where each target sequence is a data sequence containing missing data bits; S22. For any missing data bit of any target sequence, determine the supplementary sequence of the missing data bit from the other working data sequences except the target sequence, and supplement the missing data bit based on the supplementary sequence, where the supplementary sequence corresponds to the position of the missing data bit and has data; S23. Interpolate each target sequence based on the working data sequences of each device after supplementation according to a preset algorithm.

[0033] In a specific implementation process, several working data sequences with missing data are found from the working data sequences of each device as target sequences. It can be understood that each target sequence is a data sequence containing missing data bits, and the missing data bits are the data bits that need to be interpolated.

[0034] In one embodiment, in step S22, supplementing the missing data bits based on the supplementary sequence may specifically include: S221. Calculate the difference factors between each supplementary sequence and the missing data bits; S222. Use the supplementary sequence with the smallest difference factor as the matching sequence for the missing data bits; S223. Use the data corresponding to the position of the missing data bits in the matching sequence as the supplementary data for the missing data bits.

[0035] Among them, the difference factor can characterize the data difference between each supplementary sequence and the target sequence corresponding to the missing data bits within a preset window size.

[0036] It should be noted that the specific steps for interpolating the working data sequences of various types of devices using the KNN algorithm are: cleaning the data to remove abnormal data; calculating the KNN distance matrix; selecting K nearest neighbors; and filling the missing data bits based on the K nearest neighbors.

[0037] This embodiment improves the step of calculating the KNN distance matrix. In the existing KNN algorithm, it is necessary to temporarily fill the missing data before calculating the KNN distance matrix. The supplementary data in this example is the data for temporarily filling the missing data.

[0038] In step S221, the device collaboration scheduling device can first set a preset window centered on the missing data bits, and then calculate the difference factors between each supplementary sequence and the target sequence where the missing data bits are located within the preset window.

[0039] Specifically, taking the th missing data bit of the th target sequence and the th supplementary sequence of this missing data bit as an example, the difference factor between the th supplementary sequence of the th missing data bit of the th target sequence and the th target sequence within the preset window can be calculated using the following formula (1): :

[0040] In the formula, Indicates the th target sequence where the th missing data bit is located, and the th missing data bit and the th supplementary sequence within the preset window, the difference factor, Indicates the th target sequence where the th missing data bit is located, and the th missing data bit and the th supplementary sequence within the preset window, the number of data they jointly have, Indicates the th data of the th target sequence within the preset window where the th missing data bit is located, Indicates the th data of the th supplementary sequence within the preset window where the th missing data bit is located, Indicates taking the absolute value, Indicates the hyperbolic tangent function, Indicates the preset adjustment factor.

[0041] It should be noted that if within the preset window, the th target sequence where the th missing data bit is located has 8 data, while the th supplementary sequence where the th missing data bit is located only has 5 data, then is 5. In formula (1), represents the average difference of the corresponding data values at the common time points of the two sequences within the preset window. Since the more data the two sequences jointly have within the preset window, that is, the larger it is, the higher the confidence level of the calculated difference factor. And because the hyperbolic tangent function has a normalization effect, that is, normalizing the input value to between -1 and 1 (since in this embodiment is a non-negative number, so in this embodiment is to normalize to between 0 and 1).

[0042] When remains unchanged, if is larger, is closer to 1, and thus is larger; while if is smaller, is smaller, which can be understood as having a penalty effect to ensure that the difference factor does not increase excessively under low confidence.

[0043] It is understandable that in this embodiment, is used to make adjustments to which can be understood as multiplying by a weight representing the confidence level. In addition, in this embodiment, adding the natural number 1 to is to avoid the influence on the calculation result when is 0.

[0044] In one embodiment, in step S23, interpolating each target sequence based on the supplemented working data sequences of each device according to a preset algorithm may specifically include: S231. Calculate the KNN distance matrix based on the supplemented working data sequences of each device, and determine the K nearest neighbor devices of each missing data bit based on the KNN distance matrix; S232. Interpolate each missing data bit based on the supplemented working data sequences of the K nearest neighbor devices of each missing data bit.

[0045] In the specific implementation process, first use the KNN algorithm and calculate the KNN distance matrix based on the supplemented working data sequences of each device, and then determine the K nearest neighbor devices of each missing data bit based on the KNN distance matrix.

[0046] Furthermore, in step S232, each missing data bit can be interpolated using the weighted average method based on the supplemented working data sequences of the K nearest neighbor devices of each missing data bit.

[0047] It is understandable that the weighted average method can make the nearer (i.e., the higher the similarity) neighbor data contribute more to the interpolation.

[0048] In this exemplary embodiment, since the difference factor characterizes the data difference between each supplemented sequence and the target sequence where the missing data bit is located within a preset window size, on this basis, determine the matching sequence of each missing data bit based on the difference factor and perform temporary filling of the missing data bit based on the matching sequence. Then, use the KNN algorithm to perform interpolation calculation on the temporarily filled working data sequence, which can utilize the similarity and collaborative relationship between devices and greatly improve the accuracy of interpolation.

[0049] Step S3. Determine the working state of each device based on the interpolated working data sequences of each device; Step S4. Perform task scheduling on each device based on the working state of each device.

[0050] In the specific implementation process, the working state of the device can be determined by analyzing the change trend and fluctuation amplitude of the data in the interpolated working data sequences of each device.

[0051] It is understandable that the interpolated working data sequence compensates for the data loss caused by equipment failures, communication delays, or sensor malfunctions, thereby providing a more continuous and smooth working data. By monitoring and comparing the interpolated working data in real time, it is possible to identify whether the equipment is in a normal operation, warning, failure, or shutdown state, etc., thereby providing support for equipment maintenance and scheduling.

[0052] In one embodiment, in step S4, task scheduling for each device based on the working state of each device may specifically include: S41. Preset a scheduling model, where the input of the scheduling model is the working state of each device, and the output of the scheduling model is the scheduling strategy for each device; S42. Perform task scheduling for each device based on the scheduling model.

[0053] In the specific implementation process, a scheduling model can be constructed and trained through a heuristic algorithm. The working state of each device is input into the scheduling model, and the scheduling model processes and makes decisions on the working state of each device, and outputs the corresponding scheduling strategy for each device. Among them, the scheduling strategy may include: the start-stop sequence of the device, workload distribution, maintenance arrangement, etc.

[0054] Furthermore, tasks are assigned to the most suitable device according to the priority of the tasks and the corresponding scheduling strategy of each device, thereby adjusting the operation sequence and load balance of the devices, and ensuring that each device executes tasks smoothly and efficiently according to the scheduling strategy.

[0055] Furthermore, the execution situation of the device is monitored in real time, and the scheduling strategy is dynamically adjusted to cope with emergencies or changes in the device state, so as to ensure the optimized execution of different tasks.

[0056] It is understandable that task scheduling for each device based on the corresponding scheduling strategy of each device can optimize resource utilization, improve production efficiency, and reduce failure shutdown time.

[0057] In this exemplary embodiment, by obtaining various types of working data sequences of each device; then determining several target sequences based on the working data sequences of the same type of each device and interpolating each target sequence; finally, determining the working state of each device based on the interpolated working data sequences of each device and performing task scheduling for each device based on the working state of each device; thus, by using the working data sequences of the same type of multiple devices to interpolate various types of working data sequences of each device, the problem that the existing data interpolation algorithm only interpolates a single device and does not consider the collaborative relationship between devices, resulting in poor interpolation accuracy, is solved. At the same time, task scheduling based on the interpolated working data sequences of each device can better optimize resource utilization, thereby improving production efficiency.
