Obviously, the drawings described below are only some embodiments of the present invention.

DETAILED DESCRIPTION
[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0017] like Figure 1 As shown, the first aspect of the present invention provides a method for constructing a reduction motor control network and collecting data, comprising the following steps: S102: constructing a reduction motor control network, integrating the data of the reduction motors in the target area into the reduction motor control network, and initializing data acquisition parameters of the reduction motor control network; S104: setting a data collection cycle, collecting torque data information of each reduction motor within a data collection cycle through the reduction motor control network, and analyzing and processing the torque data information of the reduction motor within a data collection cycle to obtain processed torque data information; S106: constructing torque data feature change data based on time series based on the processed torque data information, introducing a dynamic Bayesian network, and inputting the torque data feature change data based on time series into the dynamic Bayesian network to update the observation state; S108: Obtain updated time-series-based torque data feature change data by observing the state update, and perform torque state anomaly identification and analysis on the updated time-series-based torque data feature change data, and generate relevant control strategies based on the anomaly identification and analysis results.
[0018] It should be noted that the present invention can monitor multiple reduction motors by constructing a reduction motor control network, so as to promptly detect abnormal conditions of the reduction motors, and then promptly control the reduction motors, avoid abnormal use of the reduction motors, and increase the service life of the reduction motors.
[0019] like Figure 2 As shown, further, in the construction and data acquisition method of the reduction motor control network, the reduction motor control network is constructed, the data of the reduction motor in the target area is integrated into the reduction motor control network, and the data acquisition parameters of the reduction motor control network are initialized, specifically including: S202: constructing a reduction motor control network, and obtaining the maximum information processing amount of the reduction motor control network within a data collection cycle and the data size information of a single number of reduction motors during data collection, and obtaining the number information of the reduction motors in the current target area; S204: Calculating the total estimated data processing volume under the number of reduction motors in the current target area based on the data size information of the single number reduction motors during data collection and the number of reduction motors in the current target area; S206: If the total estimated data processing volume under the quantity information of the reduction motors in the current target area is greater than the maximum information processing volume of the reduction motor control network within a data collection cycle, then reinitialize the quantity information of the reduction motors when performing data collection within a data collection cycle; S208: Until it is no more than the maximum information processing amount of the reduction motor control network within a data collection cycle, a data collection plan is constructed according to the number information of the reduction motors during data collection within a data collection cycle, and data collection planning is carried out according to the data collection plan.
[0020] It should be noted that, in fact, the data that needs to be collected by the reduction motor include real-time speed information, real-time torque information, real-time voltage information, real-time current information, etc. The more data that needs to be collected, the larger the data size information of a single number of reduction motors during data collection will be. For example, the data size that needs to be processed once is 10 megabytes. In fact, the processing power of the computer system has an upper limit, that is, the reduction motor control network has a maximum amount of information processing within a data collection cycle. This method can optimize the number of reduction motors during data collection within a data collection cycle based on the fact that the reduction motor control network has a maximum amount of information processing within a data collection cycle, thereby improving the rationality of data collection.
[0021] It should be noted that obtaining the maximum information processing capacity of the reduction motor control network within a data acquisition cycle specifically includes: By testing the reduction motor control network, the maximum information processing volume change characteristics of the reduction motor control network within a data acquisition cycle under each storage volume data are obtained; Introducing a graph neural network, inputting the maximum information processing volume change characteristics of the reduction motor control network under each storage volume data within a data acquisition cycle into the graph neural network, and using the storage volume data as the first node of the graph neural network; Taking the maximum information processing amount feature as the second node of the graph neural network, constructing a directed description relationship, connecting the first node and the second node based on the directed description relationship, constructing a topological structure graph, and obtaining a related adjacency matrix based on the topological structure graph; constructing a knowledge graph, inputting the related adjacency matrix into the knowledge graph for storage, obtaining the real-time data storage capacity of the current reduction motor control network, and inputting the real-time data storage capacity of the current reduction motor control network into the knowledge graph for data matching; Through data matching, the real-time data storage capacity of the current reduction motor control network below the current data storage capacity is obtained, and the maximum information processing capacity of the current reduction motor control network within a data acquisition cycle is updated according to the real-time data storage capacity of the reduction motor control network below the current data storage capacity.
[0022] It should be noted that due to the influence of data storage capacity, when the computer system is processing data, the larger the data storage capacity, the corresponding data processing capacity gradually decreases. Therefore, this method is used to update the maximum information processing capacity of the current reduction motor control network within a data acquisition cycle, thereby improving the rationality of the construction of the reduction motor control network.
[0023] Furthermore, in the construction and data collection method of the reduction motor control network, a data collection cycle is set, and the torque data information of each reduction motor within a data collection cycle is collected through the reduction motor control network, and the torque data information of the reduction motor within a data collection cycle is analyzed and processed to obtain the processed torque data information, specifically: A data collection cycle is set, and the torque data information of each reduction motor within a data collection cycle is collected through the reduction motor control network. An outlier detection algorithm is introduced, and the torque data information of each reduction motor within a data collection cycle is input into the outlier detection algorithm for outlier detection; By outlier detection, outlier point data in the torque data information of each reduction motor within a data collection cycle is obtained, and outlier point data in the torque data information of each reduction motor within a data collection cycle is deleted; After deletion, the sorted torque data information of each reduction motor within a data collection cycle is obtained and output as processed torque data information.
[0024] It should be noted that since data collection is to collect a number of data within a data collection cycle (such as 10 seconds, 20 seconds, 1 minute, etc.), the data collected within this data collection cycle may be abnormal. The outlier detection algorithm is used to delete abnormal data to make data collection more reasonable.
[0025] Furthermore, in the construction and data acquisition method of the reduction motor control network, the torque data characteristic change data based on the time series is constructed based on the processed torque data information, the dynamic Bayesian network is introduced, and the torque data characteristic change data based on the time series is input into the dynamic Bayesian network for observation state update, specifically: The processed torque data information is sorted and arranged according to the order of time points, the torque data characteristic change data based on time series is constructed, and the dynamic Bayesian network is introduced; Inputting the torque data characteristic change data based on the time series into the dynamic Bayesian network, and taking the torque data information of each timestamp in the torque data characteristic change data based on the time series as an observation state; Calculate the state transition probability value of each observation state transferring to another observation state, set the state transition probability threshold, and determine whether the state transition probability value of each observation state transferring to another observation state is greater than the state transition probability threshold; The observed state whose state transition probability value is greater than the state transition probability threshold is updated to another observed state, and the observed state whose state transition probability value is not greater than the state transition probability threshold is maintained unchanged.
[0026] It should be noted that the state transition probability value of each observation state transferring to another observation state is calculated through the dynamic Bayesian network, and the state transition probability threshold is set. The observation state with a state transition probability value greater than the state transition probability threshold is updated to another observation state, and the observation state with a state transition probability value not greater than the state transition probability threshold is maintained unchanged. In this way, the torque data characteristic change data based on the time series can be updated in time to improve the rationality of monitoring.
[0027] Furthermore, in the construction and data acquisition method of the reduction motor control network, by observing the state update, the updated torque data characteristic change data based on the time series is obtained, and the torque state abnormality identification and analysis are performed on the updated torque data characteristic change data based on the time series, specifically including: By observing the state update, the updated torque data characteristic change data based on the time series is obtained, and the torque data threshold is set to determine whether there is torque data greater than the torque data threshold in the updated torque data characteristic change data based on the time series; When there is torque data greater than the torque data threshold value in the updated torque data characteristic change data based on the time series, the corresponding reduction motor is regarded as an abnormally operating reduction motor and an early warning is issued; When there is no torque data greater than the torque data threshold value in the updated time series-based torque data characteristic change data, the output is the normal operation of the reduction motor.
[0028] It should be noted that in some special scenarios, such as abnormal external factors, the torque data of the reduction motor gradually increases within a predetermined time. When it increases to a certain limit, the reduction motor will cause abnormal operation. This method can identify abnormally operating reduction motors.
[0029] Furthermore, in the construction of the reduction motor control network and the data acquisition method, the relevant control strategies are generated based on the abnormality identification and analysis results, specifically including: Acquire the real-time torque data of the abnormal reduction motor in the abnormal identification and analysis results, and acquire the estimated maximum torque data of the current abnormal reduction motor, and set the stop working torque threshold according to the estimated maximum torque data of the current abnormal reduction motor; Determine whether the real-time torque data of the abnormal reduction motor in the abnormal identification analysis result is greater than the stop working torque threshold; When the real-time torque data of the abnormal reduction motor in the abnormal identification and analysis result is greater than the stop-work torque threshold, a stop-work instruction is issued, and the reduction motor is controlled according to the stop-work instruction; When the real-time torque data of the abnormal reduction motor in the abnormal identification and analysis results is not greater than the stop working torque threshold, the current abnormal reduction motor is continuously monitored and warned.
[0030] It should be noted that, in fact, the motor has a maximum torque parameter under the extreme working parameters. Through this method, the stopping working torque threshold can be set according to the estimated maximum torque data of the current abnormal reduction motor, so as to control the current abnormal reduction motor and improve the service life of the reduction motor.
[0031] Among them, in this method, obtaining the estimated maximum torque data of the current abnormal reduction motor specifically includes: The maximum torque data change characteristics of the reduction motor under various working environments are obtained through big data, and a prediction model for the maximum torque data change characteristics of the reduction motor is constructed based on a deep neural network; Inputting the maximum torque data change characteristics of the reduction motor under the various working environments into the reduction motor maximum torque data change characteristic prediction model for training, and obtaining the trained reduction motor maximum torque data change characteristic prediction model; Obtaining the working environment information of the current abnormal reduction motor and the maximum torque data change characteristics within a preset time, and inputting the working environment information of the current abnormal reduction motor and the maximum torque data change characteristics within a preset time into the trained reduction motor maximum torque data change characteristic prediction model for prediction; The estimated maximum torque data of the abnormal reduction motor in the current timestamp is obtained through prediction, and the estimated maximum torque data of the current abnormal reduction motor is updated according to the estimated maximum torque data of the abnormal reduction motor in the current timestamp.
[0032] It should be noted that the maximum torque data change characteristics of the reduction motor under different working environments (such as temperature, humidity, load conditions, etc.) are different. Through this method, the estimated maximum torque data of the current abnormal reduction motor can be updated to further provide the rationality of monitoring.
[0033] like Figure 3 As shown, the second aspect of the present invention provides a reduction motor control network construction and data acquisition system 4, including a memory 41 and a processor 42, the memory 41 includes a reduction motor control network construction and data acquisition method program, and when the reduction motor control network construction and data acquisition method program is executed by the processor 42, the following steps are implemented: Construct a reduction motor control network, integrate the data of the reduction motors in the target area into the reduction motor control network, and initialize the data acquisition parameters of the reduction motor control network; Setting a data collection cycle, collecting torque data information of each reduction motor within a data collection cycle through a reduction motor control network, and analyzing and processing the torque data information of the reduction motor within a data collection cycle to obtain processed torque data information; Based on the processed torque data information, torque data feature change data based on time series is constructed, a dynamic Bayesian network is introduced, and the torque data feature change data based on time series is input into the dynamic Bayesian network for observation state update; By observing the state update, the updated torque data characteristic change data based on the time series is obtained, and the torque state abnormality identification and analysis are performed on the updated torque data characteristic change data based on the time series, and the relevant control strategy is generated based on the abnormality identification and analysis results.
[0034] Furthermore, in this system, a reduction motor control network is constructed, the data of the reduction motor in the target area is integrated into the reduction motor control network, and the data acquisition parameters of the reduction motor control network are initialized, specifically including: Construct a reduction motor control network, obtain the maximum information processing volume of the reduction motor control network within a data collection cycle, and the data size information of a single reduction motor during data collection, and obtain the quantity information of the reduction motors in the current target area; Based on the data size information of a single number of reduction motors during data collection and the number information of reduction motors in the current target area, the total estimated data processing volume under the number information of reduction motors in the current target area is calculated; If the total estimated data processing volume under the quantity information of the reduction motors in the current target area is greater than the maximum information processing volume of the reduction motor control network within one data collection cycle, the quantity information of the reduction motors during data collection within one data collection cycle is reinitialized; Until it is no greater than the maximum information processing amount of the reduction motor control network within one data collection cycle, a data collection plan is constructed based on the quantity information of the reduction motors when performing data collection within one data collection cycle, and data collection planning is carried out according to the data collection plan.
[0035] Furthermore, in this system, a data collection cycle is set, and the torque data information of each reduction motor within a data collection cycle is collected through the reduction motor control network, and the torque data information of the reduction motor within a data collection cycle is analyzed and processed to obtain the processed torque data information, specifically: A data collection cycle is set, and the torque data information of each reduction motor within a data collection cycle is collected through the reduction motor control network.

[0037] Furthermore, in the system, by observing the state update, the updated torque data characteristic change data based on the time series is obtained, and the torque state abnormality identification and analysis are performed on the updated torque data characteristic change data based on the time series, specifically including: By observing the state update, the updated torque data characteristic change data based on the time series is obtained, and the torque data threshold is set to determine whether there is torque data greater than the torque data threshold in the updated torque data characteristic change data based on the time series; When there is torque data greater than the torque data threshold value in the updated torque data characteristic change data based on the time series, the corresponding reduction motor is regarded as an abnormally operating reduction motor and an early warning is issued; When there is no torque data greater than the torque data threshold value in the updated time series-based torque data characteristic change data, the output is the normal operation of the reduction motor.
