[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 2 and Figure 3 As shown, the transmission line monitoring system used in the transmission line monitoring method of the present invention may include a data processing end and a monitoring server end. The data processing end, i.e., the application layer 301, may include a display screen 1, a video control matrix 2, an office computer 3, and a first switch 4. The monitoring server end, i.e., the service layer 302, may include a second switch 5, a server 6, and a firewall 7 that communicate with the first switch 4. The server 6 may include an image recognition server, a video server, a platform server, etc. Various monitoring devices and systems, i.e., the device layer 303, such as a distributed fault location system 8, a drone 9 and its system, a meteorological system 10, a camera 11, a forest fire monitoring system 12, etc., are connected through the firewall 7 and the second switch 55.

[0036] The distributed fault location system, meteorological system, and UAV system can access server 6 via public network data protected by a firewall. The forest fire monitoring system is directly connected to fiber optic cable and can use a 100M bandwidth intranet network, supporting simultaneous viewing of 6 video streams (1 video stream requires 6M bandwidth). It is directly connected to firewall 7 to form a local area network. Server 6 provides data access to the D5000 dispatch system, which outputs traveling wave and recorded wave data through an isolation device. The monitoring room and server are directly connected via fiber optic switch. Firewall 7 is used to control access to access control devices. Through boundary protection, it can effectively avoid network layer security threats and prevent unauthorized access and attacks between different network areas. Firewall 7 can be set to a default denial mode, allowing access only according to explicit rules. It also has DOS / DDOS functionality, providing effective solutions against various denial-of-service attacks to protect the internal network from unauthorized access from external networks and ensure network bandwidth. By configuring IP / MAC binding, link-layer control is performed on hosts that can be identified by MAC address, ensuring that only users with matching IP / MAC addresses can access the server. Alarm policies can be configured on Firewall 7, leveraging its logging capabilities to record detailed and complete logs and statistical reports, enabling effective recording and statistical analysis of network access behavior. It can also be used in conjunction with encryption algorithms to protect data transmission. Plaintext can be encrypted using the MD5 algorithm to obtain ciphertext; plaintext concatenated with ciphertext can then be encrypted using the RSA algorithm before being used for data transmission. Upon receiving data, the server decrypts it using the RSA algorithm to obtain plaintext and ciphertext, then encrypts the obtained plaintext using the MD5 algorithm. This ciphertext is then compared with the transmitted ciphertext to verify the integrity of data transmission. Data storage confidentiality is enhanced by encrypting data using the national standard SM2 algorithm before storing it in the database, strengthening the system's data confidentiality mechanism.

[0037] Reference Figure 1 The transmission line monitoring method shown may include the following steps:

[0038] 101. Establish data transmission links with each external monitoring device based on the preset transmission protocol.

[0039] The monitoring equipment and systems can be connected via HTTPS to exchange data. HTTPS not only solves the problem of encrypting and preventing tampering of data transmission, but more importantly, it authenticates the data access objects to prevent data interception. The interface with the server can use a REST (GET, POST, PUT, DELETE) web service interface via HTTPS. All messages returned by the interface are encapsulated in JSON format, and all information is transmitted after being encrypted with AES. The interface requester uses an agreed-upon key to decrypt the JSON before parsing. All parameters involved in the interface request are transmitted using URL encoding, and the interface provider performs URL decoding. Chinese or mixed Chinese and English characters involved in the interface can be encoded in UTF-8 and encrypted using URL encoding before transmission to ensure reliable and secure data transmission.

[0040] 102. Obtain the power transmission line map of the target area and display it in the first display box 401 of the display interface. The power transmission line map shall have icons representing each monitoring device on at least the power transmission lines.

[0041] Transmission line maps can be created using a 3D visualization model based on electronic maps. Icons displaying information such as crossings of rivers, highways, ravines, and potential hazards (construction, trees, obstacles, wildfires) can be integrated with the transmission lines and displayed in the first frame of the screen. (Refer to...) Figure 4 The first display box shown, namely the large screen in the middle, uses a combination of maps and statistical charts to display content including the route of the line, the location of the poles and towers, the location of the substation, lightning weather, the location of forest fire hazards, the location of drone operations, the type of three-span crossings, the type of hazards, and line fault information. The data is comprehensively summarized using a map as a carrier, making it easy to understand the current situation.

[0042] 103. In response to the fault information pushed by the line dispatching system, determine the time of occurrence of the fault and the location of the fault on the transmission line diagram.

[0043] The fault information can be obtained mainly from the fault information pushed by the D5000 dispatch system. Through this fault information, we can respond immediately and locate the time of change of switch quantity (the time of change of switch quantity is the time of occurrence of the monitored fault). Based on this time node, we can obtain the location of the fault.

[0044] 104. Determine the first monitoring device within a preset range of the fault location, and obtain the alarm information of the first monitoring device at the moment of the fault occurrence based on the transmission link.

[0045] It can be linked with visual monitoring devices. By linking with distributed faults, it can display the current fault line information based on the alarm information of the monitoring equipment within the range. It can query the voltage level of the fault line, the line name, the names of the towers around the fault point, the distance of the fault point from the substation, and the latest on-site pictures before and after the fault.

[0046] 105. Based on the alarm information, determine the cause of the fault and change the icon status of the second monitoring device associated with the cause on the transmission line diagram so that the cause of the fault is displayed in the second display box 402 of the display interface when the icon of the second monitoring device is selected.

[0047] After determining the cause of the fault or alarm, the status of the corresponding tower and monitoring equipment icons is changed to indicate the cause of the fault or alarm, providing users with the most intuitive reminder. For example, if the fault is caused by a fire, the icon of the corresponding forest fire monitoring equipment can be changed to a burning flame state, and a pop-up window will display the fault information when the user selects the corresponding icon. This transmission line monitoring method realizes the centralized collection of data from various monitoring devices and monitoring systems, and can comprehensively determine the fault based on the information from each device, making efficient use of resources while making fault determination more efficient and accurate.

[0048] To further optimize this technical solution, in some specific embodiments of the present invention, alarm information reported by each monitoring device can also be displayed in the third display box 403 of the display interface, and in response to the selection operation of the target alarm information, the content of the target alarm information can be displayed and the target alarm information can be pushed to the target management personnel.

[0049] The identified and received hazard information is listed in the homepage alarm pop-up window, arranged in chronological order from top to bottom. Maintenance personnel approve each hazard message individually, and alarm records can be pushed to all followers' WeChat accounts. If it is a false alarm, the hazard record can be cleared.

[0050] For example, by integrating alarm data from distributed fault location systems and forest fire systems, after a line fault occurs, the system can immediately link up with each system to query and display the relevant alarm information generated by each system, analyze the cause of the fault, and simultaneously link up with monitoring devices around the fault point to capture images and record the situation on site before and after the fault occurred.

[0051] Furthermore, based on the characteristic information represented by the alarm information of each monitoring device, the alarm information of each monitoring device can be statistically classified and displayed in a preset format chart in the fourth display box 404.

[0052] Specifically, based on historical alarm data, statistical analysis can be performed on alarm big data from the perspectives of alarm coordinate location, alarm time distribution, and alarm trigger type. By drawing hotspot maps of hazard distribution, hazard alarm time distribution curves, and hazard type percentage charts, data such as high-incidence areas, high-incidence times, and alarm types can be analyzed. The above data, along with data such as the total length of lines in each region and the number of hazards, are displayed on a map, making it easier for users to summarize information and make more scientific and reasonable decisions.

[0053] After determining the location of the fault, the image acquisition device closest to the fault location is invoked to acquire the image or video of the fault location, and the image or video is displayed in the fifth display box 405.

[0054] For example, when alarm data is generated by the forest fire monitoring system and the distributed fault location system, the alarm linkage interface displays the processing interface in real time to pinpoint the specific cause of the line fault. After obtaining data such as high-risk areas, high-risk periods, and alarm types, during a forest fire hazard, the alarm linkage switches the forest fire system image carousel interface, and simultaneously the platform links with monitoring devices around the hazard point to take pictures. The on-site situation is then viewed through images on the forest fire alarm linkage interface displayed on the screen.

[0055] When a user clicks on a drone icon on the power transmission line map, the system responds to the selection of the drone icon closest to the fault location on the map, activating the corresponding drone to perform real-time monitoring of the fault location. This allows for viewing real-time images of the tower itself and the transmission line itself.

[0056] When an alarm is issued by a forest fire monitoring device, the system can respond to the alarm by calling the drones and / or image acquisition devices associated with the forest fire monitoring device to monitor the alarm location, in order to determine the accuracy of the alarm information, and can push real-time images and pictures from the scene.

[0057] In some specific implementations, the fault location can be determined based on waveform ranging and traveling wave ranging information at the moment the fault occurs. At least the location of the tower closest to the fault point can be obtained based on the switching signals of the transmission line, the voltage curves and current curves of each tower, and this location is then taken as the fault location.

[0058] The data accessed by the dispatching system mainly includes remote signaling data from the D5000 system and fault waveform recording data. The server actively retrieves data through the corresponding data acquisition interfaces. The remote signaling data mainly includes switch and disconnector opening and closing signals, unstored energy signals, overcurrent stage I, II, and III signals, instantaneous overcurrent stage I and II signals, and zero-sequence overcurrent stage I and II signals. The fault data mainly includes waveform recording events, curves, reports, and waveform recorder data.

[0059] The collected data is sent from the third zone of the intranet to the data receiving server in the fourth zone. The receiving server then integrates the data and sends it to the command platform server via a secure isolation device for centralized display and data linkage. Throughout the entire process, scheduling data is transmitted only in one direction; no internet data is transmitted into the intranet. Servers connected to the internet are equipped with both physical and software firewalls for dual isolation, ensuring data security.

[0060] The system fault linkage interface allows users to intuitively view relevant waveform ranging, distributed fault location data, and traveling wave ranging information when fault alarms occur. Users can also view corresponding waveform curves and compare image data before and after a fault in the corresponding section. By clicking the one-click capture button, users can issue capture commands to the tower section equipment after linkage analysis. Through comparison of image data from multiple towers, users can quickly locate whether the line fault is caused by external damage. Clicking the traveling wave curve button allows users to view the waveform data of the corresponding section.

[0061] By periodically acquiring waveform recording data and corresponding alarm information from the waveform recording interface, and combining it with distributed fault location data, the fault location can be quickly determined and the waveform curve data can be displayed. Multi-dimensional data analysis is used to analyze the causes of line faults. Historical data is used to display waveform changes before and after the fault. Remote signaling data switching quantities are recorded long-term. When abnormal changes occur in the switching quantities, the D5000 system quickly pushes corresponding change information, and the system responds with a rapid alarm. Historical data is used to locate the time points of switching quantity changes, and combined with on-site images at those time points, the cause of the fault can be quickly determined. The system can also respond to the carousel operation of the fifth display frame, displaying the latest images or videos from each image acquisition device. For example, when the forest fire system issues an alarm, it can link a camera to capture images to confirm whether there is a fire. After discovering a potential forest fire hazard, it can link the forest fire system to check the on-site situation, achieving mutual verification of information between systems. A video carousel interface is also provided for browsing forest fire monitoring system videos, allowing real-time viewing of on-site videos.
