Description

Technical Field

[0001] The present invention relates to the technical field of network convergence, and in particular to a network convergence switching device and method based on a multi-source data protocol. Background Art

[0002] With the continuous development of information technology, data exchanges between enterprises, organizations and individuals are becoming more frequent, and the number and types of data sources are increasing. Different data sources may use different data protocols, resulting in data not being able to be seamlessly integrated and transmitted, which poses great challenges to data management and application.

[0003] For example, announcement number: CN103402262B discloses a linear wireless sensor network aggregation method, wherein the linear duty cycle wireless sensor network aggregation includes time slot allocation and aggregation scheduling. In the time slot allocation stage, the initialization working cycle Tinit is a multiple of 3, and the working time slots of any three consecutive nodes except the BS are continuous and different on the time axis; in the aggregation scheduling stage, the working cycle of any node except the BS in the initial mode is Tinit, and the working time slot is set to τ. The working cycle Twork in the working mode is 3, and the working time slot is ((τ-1)mod3)+1. By setting a timer to dynamically switch between the two modes, the nodes in the network are scheduled in a duty cycle manner, which saves node energy, prolongs the network life, and determines the theoretical upper limit of the time to complete the aggregation. The non-duty cycle wireless sensor network aggregation method periodically searches and schedules all nodes in the network except the BS, and completes the aggregation in the shortest time under the linear wireless sensor network model. It is used for collision-free aggregation applications in linear wireless sensor networks.

[0004] Based on the above solutions, it is found that there are still some shortcomings in the current network convergence methods, which are specifically reflected in the following aspects: it is impossible to effectively process and integrate data from different sources and support decision-making and operation execution in complex network environments. Summary of the invention

[0010] Furthermore, the calculation formula of the data source aggregation index is as follows:

[0011] χ=Cnet*λ1+Csen*λ2+Cemb*λ3;

[0014] Furthermore, the specific calculation formula of the data source aggregation compliance coefficient is as follows:

[0015]

[0016] In the formula, β represents the data source aggregation compliance coefficient, χ represents the data source aggregation index, χ1 represents the threshold of the data source aggregation index, and Δχ represents the allowable deviation value of the data source aggregation index.

[0017] Furthermore, the specific process of obtaining evaluation information on the degree of aggregation of data sources of different protocols is as follows: based on the data source aggregation compliance coefficient, compare it with the standard value of the data source aggregation compliance coefficient. If the data source aggregation compliance coefficient is less than the standard value of the data source aggregation compliance coefficient, it means that the data sources of different protocols are not aggregated, and the data sources of different protocols are converted into data formats and standardized; if the data source aggregation compliance coefficient is greater than the standard value of the data source aggregation compliance coefficient, it means that the data sources of different protocols are aggregated.

[0018] Furthermore, the specific process of converting and standardizing the data format of network device data, sensor data and embedded device data based on the evaluation information of the degree of aggregation of data sources of different protocols is as follows: based on the evaluation information of the degree of aggregation of data sources of different protocols, the data format of network device data, sensor data and embedded device data is converted using the scripting language Python; the time fields in data sources of different protocols are unified into the same date and time format, and text data is converted into numeric data to ensure that the data types of all data fields are consistent, and missing values ​​are processed by filling in default values ​​and interpolation.

[0035] Specifically, the specific calculation process of the data source aggregation index based on network device data, sensor data and embedded device data is as follows: based on network device data, analyze the aggregation compliance of network device data, and calculate the network device data source aggregation index; based on sensor data, analyze the aggregation compliance of sensor data, and calculate the sensor data source aggregation index; based on embedded device data, analyze the aggregation compliance of embedded device data, and calculate the embedded device data source aggregation index; based on the network device data source aggregation index, sensor data source aggregation index, and embedded device data source aggregation index, assign weights to the network device data source aggregation index, sensor data source aggregation index, and embedded device data source aggregation index, and calculate the data source aggregation index.

[0036] In this implementation scheme, based on the network device data, the network devices are numbered 1, 2, 3...i...n in sequence, where n represents the total number of network devices. The calculation formula for the network device data source aggregation index is as follows:

[0038] In the formula, Cnet represents the network device data source aggregation index, which is used to measure the degree of aggregation of network device data sources, and Nnet i Indicates the data volume of the ith network device, Unet i Indicates the data update frequency of the ith network device, Ynet i represents the data integrity of the ith network device, Nnet1 represents the standard value of the network device data volume, Unet1 represents the standard value of the network device data update frequency, Ynet1 represents the standard value of the network device data integrity, ω1 represents the weight factor of the network device data volume, ω2 represents the weight factor of the network device data update frequency, and ω3 represents the weight factor of the network device data integrity. Based on the sensor data, the sensors are numbered 1, 2, 3...j...m in sequence, m represents the total number of sensors, and the calculation formula of the sensor data source aggregation index is as follows:

[0039]

[0040] In the formula, Csen represents the aggregation index of sensor data sources, which is used to measure the aggregation degree of sensor data sources, and Nsen j Indicates the amount of data from the jth sensor, Usen j Indicates the update frequency of the jth sensor data, Ysen jrepresents the data integrity of the jth sensor, Nsen1 represents the standard value of the sensor data volume, Usen1 represents the standard value of the sensor data update frequency, Ysen1 represents the standard value of the sensor data integrity, ξ1 represents the weight factor of the sensor data volume, ξ2 represents the weight factor of the sensor data update frequency, and ξ3 represents the weight factor of the sensor data integrity;

[0041] Based on the embedded device data, the embedded devices are numbered 1, 2, 3...t...d in sequence, where d represents the total number of embedded devices. The calculation formula for the embedded device data source aggregation index is as follows:

[0042]

[0043] Where Cemb represents the aggregation index of embedded device data source, which is used to measure the aggregation degree of embedded device data source, and Nemb t Indicates the data volume of the tth embedded device, Uemb t Indicates the data update frequency of the tth embedded device, Yemb t represents the data integrity of the tth embedded device, Nemb1 represents the standard value of the embedded device data volume, Uemb1 represents the standard value of the embedded device data update frequency, Yemb1 represents the standard value of the embedded device data integrity, δ1 represents the weight factor of the embedded device data volume, δ2 represents the weight factor of the embedded device data update frequency, and δ3 represents the weight factor of the embedded device data integrity.

[0044] Specifically, the specific process of assigning weights to the network device data source aggregation index, sensor data source aggregation index, and embedded device data source aggregation index is as follows: construct a data source aggregation hierarchy, extract features from the network device data source aggregation index, sensor data source aggregation index, and embedded device data source aggregation index, and compare the degree of influence of the network device data source aggregation index, sensor data source aggregation index, and embedded device data source aggregation index on the network device data source aggregation index; normalize the network device data source aggregation index, sensor data source aggregation index, and embedded device data source aggregation index through a comparison matrix to obtain the weight factors of the network device data source aggregation index, sensor data source aggregation index, and embedded device data source aggregation index.

[0045] In this implementation scheme, based on the calculated weight factors, the weights of different data sources in data aggregation can be reasonably allocated, so that the information of each data source can be more fully utilized in the data aggregation process; reasonable weight factors can make the data aggregation results more consistent with the contribution of each data source, thereby improving the accuracy and reliability of the data aggregation results; through the weight factors, a reasonable data aggregation strategy can be formulated, more attention can be paid to data sources that contribute more to the data, and their data can be used more in the data aggregation process, thereby optimizing the effect of data aggregation.

[0046] Specifically, the calculation formula of the data source aggregation index is as follows:

[0047] χ=Cnet*λ1+Csen*λ2+Cemb*λ3;

[0048] Where χ represents the data source aggregation index, which is used to measure the degree of data source aggregation. Cnet represents the network device data source aggregation index.

This improves the accuracy of the data aggregation results and optimizes the data aggregation strategy, so that the data aggregation index is more in line with the actual situation and provides more reliable data support for decision-making.

[0050] Specifically, the specific process of evaluating the degree of aggregation of data sources of different protocols is as follows: based on the data source aggregation index, compare it with the threshold of the data source aggregation index, calculate the difference between the data source aggregation index and the threshold of the data source aggregation index, compare the difference between the data source aggregation index and the threshold of the data source aggregation index with the allowable deviation value of the data source aggregation index, and calculate the data source aggregation compliance coefficient.

[0051] In this implementation scheme, evaluating the degree of aggregation of data sources of different protocols can help determine the importance and contribution of different data sources, optimize the selection and allocation of data sources, and improve data utilization and aggregation effect. At the same time, by setting the aggregation index threshold, the aggregation requirements can be finely controlled according to the specific application scenario to meet different application requirements. In short, evaluating the degree of aggregation of data sources of different protocols can help improve the efficiency and reliability of the network aggregation and exchange method of multi-source data protocols, and realize more intelligent and automated data aggregation processing.

[0052] Specifically, the specific calculation formula for the data source aggregation compliance coefficient is as follows:

[0054] Where β represents the data source aggregation compliance coefficient, which is used to measure the degree of data source aggregation compliance, χ represents the data source aggregation index, χ1 represents the threshold of the data source aggregation index, and Δχ represents the allowable deviation value of the data source aggregation index.

[0055] In this implementation, the data source aggregation compliance coefficient can help evaluate the aggregation degree of data sources, optimize data source selection and allocation, and control aggregation requirements, thereby improving the efficiency and reliability of the network aggregation exchange method based on the multi-source data protocol.

[0056] Specifically, the specific process of obtaining evaluation information on the degree of aggregation of data sources of different protocols is as follows: based on the data source aggregation compliance coefficient, compare with the standard value of the data source aggregation compliance coefficient. If the data source aggregation compliance coefficient is less than the standard value of the data source aggregation compliance coefficient, it means that the data sources of different protocols are not aggregated, and the data sources of different protocols are converted into data formats and standardized; if the data source aggregation compliance coefficient is greater than the standard value of the data source aggregation compliance coefficient, it means that the data sources of different protocols are aggregated.

[0057] In this implementation scheme, by setting and comparing standard values ​​of data source aggregation compliance coefficients, the aggregation requirements can be controlled, thereby improving data utilization and aggregation effects; obtaining evaluation information on the degree of aggregation of data sources of different protocols can help optimize the selection and allocation strategies of data sources, improve the efficiency and reliability of data aggregation processing, and thereby improve data utilization and aggregation effects.

[0058] Specifically, based on the evaluation information of the degree of aggregation of data sources of different protocols, the specific process of data format conversion and standardization of network device data, sensor data and embedded device data is as follows: based on the evaluation information of the degree of aggregation of data sources of different protocols, the data format of network device data, sensor data and embedded device data is converted using the scripting language Python; the time fields in data sources of different protocols are unified into the same date and time format, and text data is converted into numeric data to ensure that the data types of all data fields are consistent, and missing values ​​are processed by filling in default values ​​and interpolation.

[0059] In this implementation, based on the evaluation information of the degree of aggregation of data sources of different protocols, the format conversion and standardization of network device data, sensor data and embedded device data are performed through Python scripts, which helps to improve the efficiency, reliability and operability of the data aggregation and exchange method, and further promote the further optimization and application of the network aggregation and exchange method based on multi-source data protocols.

[0060] A network convergence switching device based on multi-source data protocols comprises a data acquisition and transmission module, a data processing module, a data conversion module and a data integration storage module; the data acquisition module is used to identify and connect data sources of different protocols, the data sources include network devices, sensors and embedded devices, obtain network device data, sensor data and embedded device data, and transmit the network device data, sensor data and embedded device data to a convergence node; the data transmission module is used to calculate a data source aggregation index based on the network device data, sensor data and embedded device data, which is used to measure the degree of data source aggregation, evaluate the degree of aggregation of data sources of different protocols, and obtain evaluation information of the degree of aggregation of data sources of different protocols; the data conversion module is used to perform data format conversion and standardization processing on the network device data, sensor data and embedded device data based on the evaluation information of the degree of aggregation of data sources of different protocols, convert the data into a target device protocol, and transmit the network device data, sensor data and embedded device data to the target device using the target protocol through the network convergence switching device; the data integration storage module is used to integrate and store the network device data, sensor data and embedded device data that have undergone data format conversion and standardization processing through the network convergence switching device.
