Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1, reference Figure 1-Figure 4 , which is the first embodiment of the present invention, and provides a real-time access system for power grid data, including:

[0040] The present application provides a method for effectively solving the above-mentioned problems. Next, multiple embodiments will be combined to explain in detail how to implement the real-time access system of the power grid data.

[0041] Figure 1 The system structure diagram of a real-time access system and method for power grid data is shown, including: a data acquisition module, a communication protocol selection module, a data transmission module, a data receiving module, a storage module, a data analysis module, a display module, a safety protection module, and a frequency control module;

[0042] The data acquisition module is used to collect operating status information from power grid equipment;

[0043] The communication protocol selection module is used to select a suitable communication protocol according to the data type and network environment;

[0044] The data transmission module is used to send the data collected by the data acquisition module according to the protocol selected by the communication protocol selection module;

[0045] The data receiving module is used to receive the data sent by the data transmission module;

[0046] The storage module is used to store the data received by the data receiving module;

[0047] A data analysis module, used to process and analyze the data in the storage module to identify the operating status and potential faults of the power grid equipment;

[0048] The display module is used to display the analysis results of the data analysis module to the user to assist in decision-making;

[0049] Security protection module, used to monitor data flow, prevent unauthorized access and data leakage, and protect the system from malicious attacks;

[0050] The frequency control module includes a fault frequency analysis module and a sampling frequency control module. The fault frequency analysis module calculates the fault frequency of the power grid equipment based on the analysis results provided by the data analysis module, and the sampling frequency control module adjusts the sampling frequency of the data acquisition module according to the fault frequency.

[0051] Furthermore, the data acquisition module collects various data in the power grid in real time through sensors, smart meters, monitoring equipment, etc., such as electrical quantities such as current, voltage, power, frequency, and related information such as equipment status and environmental parameters, and classifies and organizes the collected information, so that the collected information is organized in batches to form a complete file group, thereby facilitating the subsequent targeted transmission of data.

[0052] Furthermore, the communication protocol selection module can select and determine a communication protocol suitable for data transmission, such as Modbus, RS485, Ethernet, etc., to ensure effective data interaction between the acquisition device and the data access system, and then wirelessly transmit the data through the data transmission module to transmit the data to the specified location.

[0053] Furthermore, the data receiving module receives the data transmitted by the data transmission module, thereby connecting the external data to the system, and then transmits the received data to the storage module for storage. The storage module can store the data received by the data receiving module, so that it is convenient to directly extract the data when it is used next time.

[0054] Furthermore, the data analysis module can analyze the data in the storage module and use data analysis algorithms and tools to conduct in-depth analysis of the stored data to obtain valuable information such as the operation status, fault diagnosis, and trend prediction of the power grid. These analysis results can be used for power grid monitoring, scheduling decisions, and optimized operation. The results of the data analysis module are then transmitted to the display module for display, so that the staff can observe the data and results analyzed by the data analysis module.

[0055] Furthermore, the fault frequency analysis module is connected to the output end of the data analysis module, and can calculate the fault frequency of the power grid equipment according to the analysis results of the data analysis module. The output end of the fault frequency analysis module is connected to the acquisition frequency control module, which can classify the fault frequency according to the fault frequency analyzed by the fault frequency analysis module, thereby controlling the detection frequency of the data acquisition module. When it is found that the fault frequency of a certain power grid equipment or the equipment in the entire power grid equipment system is too high in a certain time period, the detection frequency of the data acquisition module will be controlled by the acquisition frequency control module to speed up, so that the fault can be discovered in time when it occurs; if the fault rate of the power grid equipment is low in a certain time period, the detection frequency of the data acquisition module will be controlled to be reduced, so that the service life of the detection equipment can be well extended.

[0056] Furthermore, the security protection module is connected in parallel with the data receiving module. When the received data is found to be dangerous, the security protection module can cut off the data transmission and delete the previous data, thereby deleting the virus carried in the data. When encountering a greater danger, the network will be automatically disconnected to avoid losses. The security protection module includes a security protection module, a data clearing module, a data truncation module, a network disconnection module, a multiple identity authentication module and a manual networking module.

[0057] Furthermore, the security protection module is connected to the output end of the data receiving module, and the security protection module is connected in parallel with the storage module, so as to detect whether the data received by the data receiving module has security risks. The output end of the security protection module is connected to the data clearing module, and the output end of the data clearing module is connected to the data transmission module and the data receiving module. When the security protection module finds a security risk, the data in the data transmission module and the data receiving module will be cleared through the data clearing module, thereby preventing the virus from remaining in the system.

[0058] Furthermore, the data truncation module can disconnect the data transmission channel of the storage module when the security protection module finds a problem, thereby preventing data with viruses from entering the storage module and causing danger to the system. The output end of the data truncation module is connected to a network disconnection module, which is connected in parallel with the storage module. When the network disconnection module finds a greater danger and closes the data transmission channel of the storage module, it will disconnect from the network to prevent further invasion of the virus.

[0059] Furthermore, after the system is connected to the network, the multi-authentication module can verify that the person who restarts the device is a staff member through multi-authentication of the user. At this time, the security protection of the security protection module will be turned on to allow the system to continue to work after the network connection. The manual networking module allows the staff to manually connect the system to the network after the danger is eliminated.

[0060] Furthermore, this embodiment also provides a real-time access method for power grid data, including:

[0061] The data acquisition module collects operating status information from power grid equipment, and the communication protocol selection module selects an appropriate communication protocol based on data characteristics and network conditions;

[0062] The data transmission module sends the data collected by the data acquisition module to the data receiving module according to the protocol selected by the communication protocol selection module, and the data receiving module receives the data and transmits it to the storage module;

[0063] The storage module temporarily caches and archives the data for a long time, the data analysis module processes and analyzes the data in the storage module, the display module displays the analysis results to the user, the security protection module monitors the data flow, and the frequency control module adjusts the data collection frequency according to the data analysis results.

[0064] This embodiment also provides a computer device, which may be a terminal, and its internal structure diagram may be as shown in FIG. Figure 2 As shown.

The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be achieved through WIFI, an operator network, NFC (near field communication) or other technologies. When the computer program is executed by the processor, a real-time access system for power grid data is realized. The display screen of the computer device can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer device can be a touch layer covered on the display screen, or a key, trackball or touchpad set on the computer device housing, or an external keyboard, touchpad or mouse, etc.

[0075] Example 2, reference Figure 1 - Figure 2 This is the second embodiment of the present invention. This embodiment provides a real-time access system for power grid data. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0076] In order to verify the effectiveness of the proposed real-time access system for power grid data, this embodiment selected two different power grid areas as research objects, named as Area A and Area B. Each area is equipped with a set of real-time access system for power grid data described in the present invention, aiming to compare the performance differences between the new system and the traditional data access method in terms of data collection efficiency, fault detection accuracy, system security, etc. Before the test, the power grid equipment in the two areas was fully inspected to ensure that the equipment was in good condition for fair comparison.

[0077] Data acquisition module configuration: High-precision sensors and smart meters are installed at key nodes of the power grid in Area A and Area B to monitor key parameters such as current, voltage, and power in real time. In addition, environmental parameter monitoring equipment such as temperature and humidity sensors are also set up to fully reflect the power grid operation environment.

[0078] Communication protocol selection module settings: According to the network environment characteristics of the power grid area, Modbus protocol was selected for area A, while Ethernet protocol was used for area B. The communication protocol selection module can automatically adapt to network changes to ensure the stability and efficiency of data transmission.

[0079] Data transmission and receiving module debugging: The data transmission module is configured to support multi-channel data transmission, and can dynamically switch communication links according to actual needs to ensure the continuity of data transmission even when a single channel has problems. The data receiving module has been rigorously tested to ensure that all data from the data transmission module can be received without error.

[0080] Storage and data analysis module configuration: The storage module not only provides temporary data caching function, but also supports long-term archiving of data to ensure that important data will not be lost. The data analysis module integrates advanced machine learning algorithms, which can conduct in-depth analysis of stored data, accurately evaluate the working status of power grid equipment, and predict potential failures.

[0081] Display module and security protection module settings: The display module uses an intuitive graphical interface to present data analysis results to users in the form of charts, which facilitates quick understanding of power grid operation. The security protection module integrates advanced security features such as firewalls, intrusion detection, and data encryption, and can respond quickly when threats are detected to ensure system safety and reliability.

[0084]

[0085] Table 2: Frequency control module effect analysis

[0086]

[0087] As can be seen from Table 1, after adopting the real-time access system for power grid data of the present invention, the data collection efficiency of Area A has been significantly improved to 98%, which is 13 percentage points higher than the 85% of the traditional system; the fault detection accuracy has also reached 99%, which is 7 percentage points higher than the traditional system in Area B. This shows that the new data access system has shown obvious advantages in data processing and fault detection. In addition, the system response time of the new system is only 1.2 seconds, which is much lower than the 3.5 seconds of Area B, showing a faster reaction speed and higher real-time performance. In terms of security protection, Area A did not have any security incidents during the entire test period, while Area B had 2 incidents, indicating that the new system also has stronger capabilities in security protection. Finally, in terms of user satisfaction rating, Area A scored 9.2 points, while Area B only scored 7.5 points, further proving that the new system has a better user experience.

[0088] It can be seen from Table 2 that through the application of the frequency control module, the fault frequency in area A has been reduced from 5 times per month to 2 times, a decrease of 60%, and the fault frequency in area B has also been reduced from 4 times per month to 1.5 times, a decrease of 62.5%. This shows that the frequency control module can effectively reduce the frequency of faults and improve the stability of power grid operation. At the same time, the detection frequency adjustment times in area A is 3 times per week, with an average detection time interval of 15 minutes, and in area B is 2 times per week, with an average detection time interval of 20 minutes. This shows that the new system can flexibly adjust the detection frequency according to actual conditions, which not only ensures the timeliness of fault detection, but also avoids unnecessary waste of resources. It is worth noting that the average life of equipment in area A has been extended by 15%, and that in area B has been extended by 10%, which not only reduces maintenance costs, but also improves the use efficiency of equipment, reflecting the great value of the present invention in practical applications.

[0089] In summary, the real-time access system for power grid data of the present invention has demonstrated significant advantages in many aspects such as data acquisition efficiency, fault detection accuracy, system response time, security and user experience. In particular, through the application of the frequency control module, the fault frequency is effectively reduced and the equipment life is significantly extended, which fully demonstrates the technical innovation and practical application value of the present invention.
