Background Art

[0002] In modern data acquisition and transmission systems, concentrators play a crucial role. They are responsible for collecting data from multiple data acquisition devices and transmitting it to a central processing unit or a data management system. However, with the increase in the types of data acquisition devices and the diversification of communication protocols, concentrators face many challenges when processing data from different devices. Traditional data acquisition methods usually rely on specific hardware interfaces and communication protocols, which limits the flexibility and scalability of data acquisition systems. When a new data acquisition device is introduced into the system, it often requires cumbersome configuration and debugging to ensure its normal communication with the concentrator. In addition, different devices may use different data formats and communication protocols, which further increases the complexity and cost of data processing.

Brief Description of the Drawings

[0069] Figure 1 It is a schematic diagram of a plug-and-play data acquisition method for a concentrator based on a general protocol. Detailed Embodiment

[0070] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0071] In one embodiment of the present invention, the present invention provides a plug-and-play data acquisition method and system for a concentrator based on a general protocol, and the method includes:

[0072] S1. Obtain device acquisition data through a data acquisition device, perform data feature extraction to obtain device acquisition feature data, determine the general data protocol and the general device protocol, and obtain a protocol classification data group and a protocol classification device group;

[0073] S2. Perform data grouping and packaging to obtain device information with the same protocol and data with the same protocol, compare the number of general protocols of the two types of devices and data, and perform protocol conversion according to the comparison result to obtain converted data;

[0074] S3. Establish a device centralized processing link, obtain the protocol information of the data acquisition device, retrieve the processing protocol, perform protocol matching, and then transmit the device acquisition data to obtain channel transmission data;

[0075] S4. Calculate the data transmission health coefficient, perform data anomaly determination based on the data transmission health coefficient, and perform protocol update according to the determination result, as Figure 1 described.

[0076] The working principle of the above technical solution is as follows: The data acquisition device first obtains data from different devices. Feature extraction is performed on these data with the aim of identifying key data features. The general protocol of the data (such as Modbus, OPCUA, etc.) and the general protocol of the devices are determined to classify the data and devices with the same protocol separately. The classified data and devices form a protocol classification data group and a protocol classification device group respectively for unified processing. The data and devices with the same protocol are grouped and packaged, which can reduce the complexity and resource consumption in data and device information processing. The number of general protocols of the devices with the same protocol and the data with the same protocol is compared to find out the classification (data or device) with a smaller protocol complexity. According to the comparison result, necessary protocol conversion is carried out to ensure that the data can be correctly transmitted and understood between different devices. A device centralized processing link is established, which will serve as the channel for data transmission between the acquisition device and the concentrator. The protocol information of the data acquisition device is obtained to ensure that the concentrator can correctly identify and process the data from different devices. The corresponding processing protocol is retrieved for protocol matching to ensure that the data will not be lost or in error due to protocol mismatch during transmission.

[0077] The transmission device collects data to obtain the channel transmission data, which is the final output of the data from the acquisition device to the concentrator. The data transmission health coefficient is calculated, and this coefficient reflects the stability and reliability of data transmission. Abnormality determination is performed according to the data transmission health coefficient. If the coefficient is lower than the preset threshold, it is considered that there is a problem with data transmission. According to the determination result, the protocol is updated or adjusted to improve the stability and efficiency of data transmission.

[0078] The technical effects of the above technical solution are as follows: Through feature extraction and protocol classification, unnecessary data processing steps are reduced, and the efficiency and accuracy of data acquisition are improved. Through protocol conversion and the establishment of a centralized processing link, redundancy and errors in data transmission are reduced, and the cost of data transmission is lowered. Through the calculation of the data transmission health coefficient and abnormality determination, problems in data transmission can be discovered and solved in a timely manner, enhancing the stability of data transmission. This method is based on a general protocol and can support the access of multiple devices and data, improving the scalability and flexibility of the system. Through protocol update and the maintenance of the centralized processing link, the maintenance work of the system is simplified, and the maintenance cost is reduced. The plug-and-play data acquisition method and system for a concentrator based on a general protocol improve the efficiency and stability of data acquisition, transmission, and processing through a series of technical means, and reduce the cost and maintenance difficulty of the system.

[0079] In an embodiment of the present invention, S1 includes:

[0086] Obtain preset device general protocol types to classify the device general protocol, and then group the data acquisition devices by protocol to obtain multiple protocol classification device groups.

[0087] The working principle of the above technical solution is as follows: Obtain the specific requirements for data acquisition, including data types, acquisition frequencies, accuracy requirements, etc. According to these requirements, select or configure the corresponding data acquisition devices. These devices include sensors, instruments, intelligent devices, etc., which can directly obtain the required raw data. Use the selected data acquisition devices to obtain raw data from the environment, and this data may contain noise, redundant information, etc. Perform preprocessing on the raw data, including steps such as data cleaning, format conversion, and denoising, to obtain more accurate and reliable device-acquired data. Extract features from the preprocessed device-acquired data. The purpose is to extract key information or features from a large amount of data, and these features can represent the essence or change trend of the data. According to the extracted feature data, determine the general data protocol of the data acquisition device according to preset rules. This method classifies the general protocols for data and devices respectively, which is convenient for obtaining devices with the same protocol and data with the same protocol, facilitating batch transmission processing of a large number of data or devices with the same protocol, etc., improving the efficiency of data protocol processing, and being more intelligent and automated. The general data protocol refers to the general format or standard used during data transmission, storage, and processing. Determine the general device protocol of the device according to the data acquisition device to which the feature data belongs. The general device protocol refers to the communication protocol or data format followed by the device when communicating with other devices or systems. Obtain the preset types of general data protocols, classify the determined general data protocols, so as to group the device-acquired feature data according to the protocol type, forming multiple protocol classification data groups. Obtain the preset types of general device protocols, classify the determined general device protocols, so as to group the data acquisition devices according to the protocol type, forming multiple protocol classification device groups.

[0088] The technical effects of the above technical solution are as follows: This method classifies the general protocols for data and devices respectively, facilitating the acquisition of devices with the same protocol and data with the same protocol, and facilitating the batch transmission and processing of a large number of data or devices with the same protocol, etc., improving the efficiency of data protocol processing, and being more intelligent and automated. By clarifying the acquisition requirements and selecting appropriate acquisition devices, the required data can be obtained more quickly and accurately. The preprocessing step can reduce data redundancy and noise and improve data quality. By determining the general data protocol and the general device protocol, the data between different devices can be transmitted and processed according to a unified standard, enhancing the generality and interoperability of the data. It realizes the seamless integration and sharing of data, reducing the difficulty and cost of data integration and processing. Grouping the data according to the protocol type helps in the classified management and storage of data, improving the efficiency and convenience of data protocol management. This grouping method also facilitates data protocol transmission, enabling analysts to locate the required data set more quickly. The data acquisition method based on the general protocol can support a variety of different types of data acquisition devices and data formats, improving the scalability and flexibility of the system. The system can easily add new acquisition devices or data types without making a large number of modifications or reconstructions to the system. This method can achieve efficient and accurate data acquisition and processing, improving the scalability and flexibility of the system.

[0089] In one embodiment of the present invention, S2 includes:

[0090] Pack the data acquisition device information of each protocol classification device group to obtain device information with the same protocol (including device information with the same protocol formed by a single data acquisition device);

[0091] Pack the device acquisition characteristic data of each protocol classification data group to obtain data with the same protocol (including data with the same protocol formed by the device acquisition characteristic data of a single device);

[0092] Compare the number of general device protocols of the device information with the same protocol with the general data protocol of the data with the same protocol;

[0093] When the number of general device protocols of the device information with the same protocol is less than the general data protocol of the data with the same protocol, convert the general data protocol of the device acquisition characteristic data into the general device protocol of the data acquisition device corresponding to the data;

[0094] When the number of general data protocols of the data with the same protocol is less than the general device protocol of the device with the same protocol, convert the general device protocol of the data acquisition device into the general data protocol of the device acquisition characteristic data corresponding to the device;

[0095] Obtain the converted device information with the same protocol or data with the same protocol through protocol conversion.

[0096] The working principle of the above technical solution is as follows: For each protocol classification device group, the internal data acquisition device information is packaged to form device information of the same protocol. These information includes but is not limited to device ID, device type, device location, etc., and all these information follow the same general device protocol. For each protocol classification data group, the internal device acquisition feature data is packaged to form data of the same protocol. These data are processed according to the same general data protocol, so they have similar data structures and formats. Compare the number of general device protocols of the device information of the same protocol with the general data protocol of the data of the same protocol. Find out the type with the least complex number of protocols in comparison, such as devices or data, and perform protocol conversion from one to the other to facilitate a large amount of unified processing of the same protocol. When the number of general device protocols of the device information of the same protocol is less than the general data protocol of the data of the same protocol, it means that the number of data protocols is more complex than the number of device protocols. At this time, it is necessary to convert the general data protocol of these data into the general device protocol of the corresponding data acquisition device to ensure data consistency and processability. On the contrary, when the number of general data protocols of the data of the same protocol is less than the general device protocol of the device information of the same protocol, it indicates that the number of device protocols is more complex than the number of data protocols. At this time, it is necessary to convert the general device protocol of these devices into the general data protocol of the corresponding device acquisition feature data to ensure the smooth communication and data transmission between devices. After protocol conversion, the converted device information of the same protocol or data of the same protocol is obtained. These data or information have been processed according to the unified protocol standard.

[0097] The technical effects of the above technical solution are as follows: Through protocol conversion, it is ensured that all data follow the same protocol standard, improving data consistency and processability. This helps to reduce data errors and conflicts and improve data quality and reliability. Protocol conversion enables data between different devices to be transmitted and processed according to a unified protocol, enhancing device interoperability. This can achieve seamless integration and collaborative work of devices, improving the overall performance and efficiency of the system. By classifying and packaging different devices and data according to the protocol and then performing necessary protocol conversion, the difficulty and complexity of system integration are reduced. This enables the system to more quickly adapt to new device and data types, improving the scalability and flexibility of the system. After protocol conversion, all data follow the same protocol standard, which can optimize data transmission and processing efficiency. For example, it can reduce redundancy and errors in data transmission, improve the speed and accuracy of data transmission; at the same time, it can also simplify the data processing process and improve the efficiency and accuracy of data processing.

[0098] In one embodiment of the present invention, S3 includes:

[0099] Obtain preset plug-and-play information, and set plug-and-play nodes according to the preset plug-and-play information;

[0100] Connect the data acquisition device to the concentrator through a plug-and-play node to obtain a device centralized processing link;

[0101] Obtain a data acquisition and transmission channel through the device centralized processing link;

[0102] The concentrator obtains the information of devices with the same protocol or the protocol information of data with the same protocol of the data acquisition device through the data acquisition and transmission channel;

[0103] Invoke the corresponding processing protocol according to the said protocol information;

[0104] Match the said protocol information with the processing protocol to obtain protocol matching information;

[0105] Transmit the device-acquired data according to the protocol matching information to obtain channel-transmitted data.

[0106] The working principle of the above technical solution is as follows: Obtain preset plug-and-play information, which includes key parameters such as device type, communication protocol, data format, etc., and is used to guide the access of devices and the processing of data. According to this information, the system sets up plug-and-play nodes, which serve as the interfaces between the data acquisition devices and the concentrator, and are responsible for device access, data forwarding and processing. The data acquisition device is connected to the concentrator through the plug-and-play node to form a device centralized processing link. This link is the channel for device data transmission and processing, ensuring that data can be efficiently and accurately transmitted from the device to the concentrator.

[0107] Through the device centralized processing link, the system obtains one or more data acquisition and transmission channels. These channels are the bridges for data transmission between the data acquisition device and the concentrator, and are responsible for transmitting the data collected by the device to the concentrator for processing in real time. The concentrator obtains the information of devices with the same protocol or the protocol information of data with the same protocol of the data acquisition device through the data acquisition and transmission channel. This information includes the communication protocol, data format, etc. of the data. According to the obtained protocol information, the system invokes the corresponding processing protocol. These processing protocols are preset by the system and are used to parse, convert and process data with different protocols. Match the obtained protocol information with the invoked processing protocol to obtain protocol matching information. Through the above protocol processing and matching, the processing efficiency of device-acquired data from different sources and different protocols can be improved; this information indicates which protocol the data should be processed and transmitted according to. According to the protocol matching information, the system transmits the device-acquired data. After the data undergoes necessary processing (such as format conversion, data cleaning, etc.), it is transmitted through the channel to the specified target location (such as a database, an analysis system, etc.).

[0108] The technical effects of the above technical solution are as follows: By presetting the plug-and-play information and plug-and-play nodes, the system can quickly identify and connect to new data acquisition devices without manual configuration and debugging, greatly improving the efficiency of device connection. The system can support various types of data acquisition devices and communication protocols. Through the expansion of plug-and-play nodes, new devices and data types can be easily connected, enhancing the scalability and flexibility of the system. By establishing the device centralized processing link and data acquisition and transmission channels, the system can efficiently transmit and process the data collected by the devices, reducing the data transmission delay and error rate, and improving the accuracy and reliability of the data. Through the preset processing protocol and protocol matching mechanism, the system can automatically identify and process data of different protocols, simplifying the data processing process and reducing the data processing difficulty and cost. Through the optimization of the above work process and the realization of technical effects, the overall performance of the system is improved, including aspects such as device connection speed, data transmission efficiency, and data processing ability.

[0109] In one embodiment of the present invention, S4 includes:

[0110] According to the data transmission health coefficient calculated based on the data transmitted through the channel, compare the data transmission health coefficient with a preset data health threshold to obtain a data health comparison result;

[0111] The calculation formula of the data transmission health coefficient is:

[0112]

[0113] where SJK is the data transmission health coefficient, n is the number of independent device acquisition characteristic data, A i is the actual acquisition data of the i-th device acquisition characteristic data in the data acquisition device, and B i is the actual acquisition data of the i-th device acquisition characteristic data in the concentrator after being transmitted through the general protocol conversion;

[0114] Judge the data transmission according to the data health comparison result to obtain data anomaly determination information;

[0115] Update the general protocol according to the data anomaly determination information.

[0116] The working principle of the above technical solution is: Calculate the data transmission health coefficient according to the data transmitted through the channel. Compare the calculated data transmission health coefficient with the preset data health threshold. The threshold is used to judge whether the data transmission is in a healthy state.

[0117] If the data transmission health coefficient is higher than or equal to the threshold, the data transmission is considered healthy; if it is lower than the threshold, the data transmission is considered to have anomalies or potential problems. Based on the result of the data health comparison, the system determines the data transmission and generates data anomaly determination information. This information will clearly indicate whether there are anomalies in the data transmission, as well as the degree and possible causes of the anomalies. According to the data anomaly determination information, the system updates the general protocol, including adjusting communication parameters, optimizing data transmission strategies, fixing vulnerabilities or errors in the protocol, etc. The purpose of the update is to improve the quality and efficiency of data transmission and ensure that data can be accurately and reliably transmitted to the target location.

[0118] The technical effects of the above technical solution are as follows: By calculating the data transmission health coefficient and comparing it with the preset threshold, the system can timely detect problems in data transmission and take corresponding measures for repair and optimization, thereby improving the quality of data transmission. The introduction and monitoring of the data transmission health coefficient enable the system to continuously evaluate the status of data transmission, timely detect potential problems and handle them, thereby enhancing the stability and reliability of the system. Through the above formula, the data changes of the device acquisition data collected by all data acquisition devices before and after protocol adjustment can be calculated, and further the influence degree of the protocol adjustment degree data can be obtained. The greater the influence degree, the greater the value of 1 - influence degree, and the smaller the health coefficient; updating the general protocol according to the data anomaly determination information makes the protocol update more accurate and efficient. This can reduce unnecessary protocol updates and debugging work, and improve the operation efficiency and performance of the system. Through the automated data transmission health monitoring and protocol update mechanism, the system can reduce manual intervention and maintenance costs, and improve the automation and intelligence level of the system. The improvement of data transmission quality and the enhancement of system stability will directly improve the user experience.

[0124] The working principle of the above technical solution is as follows: The data acquisition device first obtains data from different devices. Feature extraction is performed on these data to identify key data features. Determine the general protocol of the data (such as Modbus, OPCUA, etc.) and the general protocol of the device, which is to classify the data and devices with the same protocol separately. The classified data and devices form a protocol classification data group and a protocol classification device group respectively for unified processing. Group and package the data and devices with the same protocol, which can reduce the complexity and resource consumption in data and device information processing. Compare the number of general protocols of the devices with the same protocol and the data with the same protocol to find out the classification (data or device) with less protocol complexity. According to the comparison result, perform necessary protocol conversion to ensure that the data can be correctly transmitted and understood between different devices. Establish a device centralized processing link, which will serve as the channel for data transmission between the acquisition device and the concentrator. Obtain the protocol information of the data acquisition device to ensure that the concentrator can correctly identify and process the data from different devices.

Extract features from the preprocessed device-acquired data, with the aim of extracting key information or features from a large amount of data, and these features can represent the essence or change trend of the data. According to the extracted feature data, determine the general data protocol of the data acquisition device according to the preset rules. This method classifies the general protocols for data and devices respectively, which is convenient for obtaining devices with the same protocol and data with the same protocol, facilitating batch transmission processing of a large number of data or devices with the same protocol, etc., improving the efficiency of data protocol processing, and being more intelligent and automated. The general data protocol refers to the general format or standard used in the process of data transmission, storage, and processing.

Obtain the preset types of general data protocols, classify the determined general data protocols, so as to group the device-acquired feature data according to the protocol type, forming multiple protocol classification data groups. Obtain the preset types of general device protocols, classify the determined general device protocols, so as to group the data acquisition devices according to the protocol type, forming multiple protocol classification device groups.

[0136] The technical effects of the above technical solution are as follows: This method classifies the general protocols for data and devices respectively, facilitating the acquisition of devices with the same protocol and data with the same protocol, enabling batch transmission and processing of a large number of data or devices with the same protocol, etc., improving the efficiency of data protocol processing, and making it more intelligent and automated.

[0137] In an embodiment of the present invention, the protocol judgment and conversion module includes:

[0138] Pack the data acquisition device information of each protocol classification device group to obtain device information with the same protocol (including devices with the same protocol formed by individual data acquisition devices);

[0140] Compare the number of general device protocols of the device information with the same protocol with the general data protocol of the data with the same protocol;

[0141] When the number of general device protocols of the device information with the same protocol is less than the general data protocol of the data with the same protocol, convert the general data protocol of the device acquisition feature data into the general device protocol of the corresponding data acquisition device of the data;

[0142] When the number of general data protocols of the data with the same protocol is less than the general device protocol of the device with the same protocol, convert the general device protocol of the data acquisition device into the general data protocol of the device acquisition feature data corresponding to the device;

[0143] Obtain the converted device information with the same protocol or data with the same protocol through protocol conversion.

[0144] The working principle of the above technical solution is as follows: For each protocol classification device group, the internal data acquisition device information is packaged to form device information with the same protocol. These information include but are not limited to device ID, device type, device location, etc., and all these information follow the same device general protocol. For each protocol classification data group, the internal device acquisition feature data is packaged to form data with the same protocol. These data are processed according to the same data general protocol, so they have similar data structures and formats. Compare the number of device general protocols of the device information with the same protocol with the data general protocol of the data with the same protocol. Find out the type with the least complex protocol quantity in comparison, such as device or data, and perform protocol conversion from one party to the other party to facilitate a large amount of unified processing of the same protocol. When the number of device general protocols of the device information with the same protocol is less than the data general protocol of the data with the same protocol, it means that the number of data protocols is more complex than the number of device protocols. At this time, it is necessary to convert the data general protocol of these data into the device general protocol of the corresponding data acquisition device to ensure the consistency and processability of the data. On the contrary, when the number of data general protocols of the data with the same protocol is less than the device general protocol of the device information with the same protocol, it indicates that the number of device protocols is more complex than the number of data protocols. At this time, it is necessary to convert the device general protocol of these devices into the data general protocol of the corresponding device acquisition feature data to ensure the smooth communication and data transmission between devices. After the protocol conversion, the converted device information with the same protocol or data with the same protocol is obtained. These data or information have been processed according to the unified protocol standard.

[0145] The technical effects of the above technical solution are as follows: Through protocol conversion, it is ensured that all data follow the same protocol standard, improving the consistency and processability of the data. This helps to reduce data errors and conflicts and improve the quality and reliability of the data. Protocol conversion enables data between different devices to be transmitted and processed according to a unified protocol, enhancing the interoperability of the devices. This can achieve seamless integration and collaborative work of the devices, improving the overall performance and efficiency of the system. By classifying and packaging different devices and data according to the protocol and then performing necessary protocol conversion, the difficulty and complexity of system integration are reduced. This enables the system to adapt to new device and data types more quickly, improving the scalability and flexibility of the system. After protocol conversion, all data follow the same protocol standard, which can optimize the data transmission and processing efficiency. For example, it can reduce redundancy and errors in data transmission, improve the speed and accuracy of data transmission; at the same time, it can also simplify the data processing process and improve the efficiency and accuracy of data processing.

[0146] In one embodiment of the present invention, the protocol transmission module includes:

[0147] Obtain preset plug-and-play information and set up plug-and-play nodes according to the preset plug-and-play information;

[0148] Connect the data acquisition device to the concentrator through the plug-and-play node to obtain a device centralized processing link;

[0149] Obtain a data acquisition transmission channel through the device centralized processing link;

[0150] The concentrator obtains the same-protocol device information or protocol information of the same-protocol data of the data acquisition device through the data acquisition transmission channel;

[0151] Retrieve the corresponding processing protocol according to the protocol information;

[0152] Match the protocol information with the processing protocol to obtain protocol matching information;

[0153] Transmit the device-acquired data according to the protocol matching information to obtain channel-transmitted data.

[0154] The working principle of the above technical solution is as follows: Obtain preset plug-and-play information, which includes key parameters such as device type, communication protocol, and data format, and is used to guide the access of devices and the processing of data. According to this information, the system sets up plug-and-play nodes, which serve as interfaces between data acquisition devices and concentrators, and are responsible for device access, data forwarding, and processing. The data acquisition device is connected to the concentrator through the plug-and-play node to form a device centralized processing link. This link is the channel for device data transmission and processing, ensuring that data can be efficiently and accurately transmitted from the device to the concentrator.

[0155] Through the device centralized processing link, the system obtains one or more data acquisition transmission channels. These channels are the bridges for data transmission between data acquisition devices and concentrators, and are responsible for real-time transmission of the data collected by the devices to the concentrators for processing. The concentrator obtains the same-protocol device information or protocol information of the same-protocol data of the data acquisition device through the data acquisition transmission channel. These information includes the communication protocol, data format, etc. of the data. According to the obtained protocol information, the system retrieves the corresponding processing protocol. These processing protocols are preset by the system and are used to parse, convert, and process data of different protocols. Match the obtained protocol information with the retrieved processing protocol to obtain protocol matching information. This information indicates which protocol the data should be processed and transmitted according to. According to the protocol matching information, the system performs the transmission of the device-acquired data. After necessary processing (such as format conversion, data cleaning, etc.), the data is transmitted through the channel to the specified target location (such as a database, an analysis system, etc.).

[0156] The technical effects of the above technical solution are as follows: By presetting the plug-and-play information and plug-and-play nodes, the system can quickly identify and connect to new data acquisition devices without manual configuration and debugging, greatly improving the efficiency of device connection. The system can support various types of data acquisition devices and communication protocols. Through the expansion of plug-and-play nodes, new devices and data types can be easily connected, enhancing the scalability and flexibility of the system. By establishing a device centralized processing link and a data acquisition and transmission channel, the system can efficiently transmit and process the data collected by the devices, reducing the data transmission delay and error rate, and improving the accuracy and reliability of the data. Through the preset processing protocol and protocol matching mechanism, the system can automatically identify and process data of different protocols, simplifying the data processing process and reducing the data processing difficulty and cost. Through the optimization of the above work process and the realization of technical effects, the overall performance of the system is improved, including aspects such as device connection speed, data transmission efficiency, and data processing ability.

[0157] In one embodiment of the present invention, the data health monitoring module includes:

[0158] Calculate the data transmission health coefficient according to the data transmitted through the channel, and compare the data transmission health coefficient with a preset data health threshold to obtain a data health comparison result;

[0159] The calculation formula of the data transmission health coefficient is:

[0160]

[0161] where SJK is the data transmission health coefficient, n is the number of independent device acquisition characteristic data, A i is the actual acquisition data of the i-th device acquisition characteristic data in the data acquisition device, and B i is the actual acquisition data of the i-th device acquisition characteristic data in the concentrator after being transmitted through the general protocol conversion;

[0162] Judge the data transmission according to the data health comparison result to obtain data anomaly determination information;

[0163] Update the general protocol according to the data anomaly determination information.

[0164] The working principle of the above technical solution is: Calculate the data transmission health coefficient according to the data transmitted through the channel. Compare the calculated data transmission health coefficient with the preset data health threshold. The threshold is used to judge whether the data transmission is in a healthy state.

[0165] If the data transmission health coefficient is higher than or equal to the threshold value, the data transmission is considered healthy; if it is lower than the threshold value, it is considered that there are abnormalities or potential problems in the data transmission. According to the result of the data health comparison, the system determines the data transmission and generates data anomaly determination information. This information will clearly indicate whether there are anomalies in the data transmission, as well as the degree of the anomaly and the possible reasons. According to the data anomaly determination information, the system updates the general protocol, including adjusting communication parameters, optimizing data transmission strategies, repairing vulnerabilities or errors in the protocol, etc. The purpose of the update is to improve the quality and efficiency of data transmission and ensure that the data can be accurately and reliably transmitted to the target location.

[0166] The technical effects of the above technical solution are as follows: By calculating the data transmission health coefficient and comparing it with the preset threshold value, the system can timely discover problems in data transmission and take corresponding measures for repair and optimization, thereby improving the quality of data transmission. The introduction and monitoring of the data transmission health coefficient enable the system to continuously evaluate the state of data transmission, timely discover potential problems and handle them, thereby enhancing the stability and reliability of the system. Updating the general protocol according to the data anomaly determination information makes the protocol update more accurate and efficient. This can reduce unnecessary protocol updates and debugging work and improve the operating efficiency and performance of the system. Through the automated data transmission health monitoring and protocol update mechanism, the system can reduce manual intervention and maintenance costs and improve the automation and intelligence levels of the system. The improvement of data transmission quality and the enhancement of system stability will directly improve the user experience.
