Description

Technical Field

[0001] The utility model belongs to the technical field of patrol inspection online monitoring, and in particular relates to a transmission line remote patrol inspection online monitoring device based on MESH networking high-definition video images. Background Art

[0002] With the rapid development of the national economy, the demand for electricity in all walks of life is increasing, and the requirements for the quality of power supply (stability, uninterruptedness and accompanying services) provided by the power supply department are also getting higher and higher. Therefore, the safety of the power grid operation of long-distance high-voltage transmission lines is particularly important.

[0003] Because ultra-high voltage transmission lines extend for tens or even hundreds of kilometers and are located in diverse environments, they are significantly affected by the geographical environment and climate. Power outages every year are primarily caused by line accidents.

[0004] Traditional transmission line inspections rely primarily on periodic inspections by maintenance personnel. While these systems can detect equipment hazards, they lack the ability to detect specific environments and climates due to their inherent limitations. During inspection intervals, they also cannot accurately monitor changes in external forces within the line corridor. This lack of monitoring can easily lead to line accidents before the next inspection. Therefore, online monitoring systems for ultra-high voltage transmission lines have emerged.

[0005] In order to achieve timely and accurate prediction before power grid accidents occur and eliminate potential line accident hazards in the bud; in order to use scientific and technological means to enable line personnel to quickly determine the point of accident after a transmission equipment accident occurs, and reduce and lower the difficulty of accident investigation; in order to solve the current contradiction between the shortage of transmission line personnel and the rapid growth of transmission lines and the difficulty of patrolling some special areas, it is urgently necessary to study and gradually introduce the use of new technologies, use scientific and technological means to further enhance the reliability of the operation of the Inner Mongolia East Power Grid, and gradually realize the digital, networked, and intelligent modern management model of my country's power grid.

[0006] Due to the vast coverage of my country's power grid, long transmission distances, complex terrain, and the fact that some areas are located in uninhabited areas, data transmission and communication methods are key to the transmission line monitoring system's ability to perform real-time online monitoring of the lines. Although wireless networks such as China Mobile, China Unicom, and China Telecom have relatively wide coverage, and optical fibers have been installed in most transmission lines, there are still some drawbacks and difficulties in the communication and transmission of the transmission line online monitoring system:

[0007] 4G and GPRS communication costs are low, and the initial cost investment is also small. However, micro-meteorological online monitoring systems generally operate in remote mountainous areas. GPRS and 4G signal coverage is very limited, and the signal is also very unstable, which cannot meet the application requirements of real-time data communication of micro-meteorological online monitoring systems.

[0008] Overhead transmission lines are basically laid with optical fiber, but the optical fiber interfaces are very limited. At the same time, some power supply companies currently provide optical fiber interfaces, but are generally reluctant to mix optical fiber ports with power-specific transmission. Therefore, the use of optical fiber for meteorological data transmission also has certain limitations.

[0009] In view of the above situation, it is necessary to find new communication methods to meet the communication application requirements of online monitoring systems for transmission lines in different regions.

[0010] Through the above analysis, the problems and defects of the existing technology are as follows:

[0011] (1) 4G and GPRS communication costs are low, and the initial cost investment is also small, but the micro-meteorological online monitoring system generally operates in remote mountainous areas. The GPRS and 4G signal coverage is very limited, and the signal is also very unstable, which cannot meet the application requirements of real-time data communication of the micro-meteorological online monitoring system.

[0012] (2) Overhead transmission lines are basically laid with optical fibers, but the optical fiber interfaces are very limited. At the same time, some power supply companies currently provide optical fiber interfaces, but are generally unwilling to mix optical fiber ports with power-specific transmission. Therefore, the use of optical fibers for meteorological data transmission also has certain limitations. Utility Model Content

[0070] Appearance and styling

[0072] Base station control box interface such as Figure 2 shown.

[0073] Power interface specifications such as Figure 4 shown.

[0074] Installation connection diagram Figure 5 shown.

[0075] Note: The black sections (Antenna 1-1 and Antenna 1-2) in the diagram are transmitting coverage antennas, while the red sections (Antenna 2-1 and Antenna 2-2) are receiving coverage antennas. These serve as the structural and configuration distinction between the MESH base station and the remote terminal. (Dome 2) is an expansion requirement, allowing for the addition of an additional surveillance dome camera. This product has different internal configurations based on the functional requirements of the MESH base station and the remote terminal. Therefore, the base station cannot be used as a remote terminal.

[0076] Combining this product's base station and hotspot creates a data transmission and video surveillance network based on a wireless mesh private network. The hotspot's cascading function effectively extends base station coverage, enhancing network robustness and flexibility.

[0080] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0081] This utility model's transmission line mesh-based HD video image remote inspection and online monitoring device primarily relies on Wi-Fi mesh wireless networking technology to enable remote monitoring of transmission lines. Through the collaboration of multiple components housed within the housing, the device transmits HD video images via a wireless network to a remote monitoring terminal, enabling real-time monitoring of transmission lines and fault warnings. The D12 input and speaker jacks on the front of the housing provide power and audio input, while the dome camera's network port works in conjunction with the camera's power supply to provide HD video surveillance and transmit video signals to a remote monitoring center.

[0082] In the first step, after the device is powered on, the antennas within the MESH base station begin operating. The transmitting antennas (antenna 1-1 and antenna 1-2) transmit the video surveillance signals and sensor data collected by the device over the wireless network to nearby MESH base station nodes or hotspots. The receiving antennas (antenna 2-1 and antenna 2-2) receive feedback signals from other base stations or monitoring points, establishing a stable wireless communication link. Leveraging the self-organizing capabilities of the MESH network, multiple base station nodes operate simultaneously through different channels, ensuring stable transmission of video signals across the wireless network and effectively preventing interference and signal loss.

[0083] The second step is to connect the HD camera (dome camera) to the network and remotely debug it through the dome camera's network port and debugging port. The dome camera uses MIMO technology in a 2T2R architecture to transmit HD video to the MESH base station at a bandwidth of up to 866 Mbps. This HD video is transmitted using the device's built-in LPTP and HPMP protocols. These proprietary protocols ensure interference immunity and low latency during video and data transmission, enabling remote monitoring images to be presented in exceptionally real-time and clear detail.

[0084] The third step is to connect the feeder interface to the device's power management module to ensure continuous and stable operation. The device supports both AC 220V and DC 12V power supplies, adapting to various field conditions. With the feeder interface and power supply connected, the device maintains long-term, uninterrupted operation, making it particularly suitable for remote monitoring of transmission lines.

[0085] Fourth, the device's control box houses multiple functional modules, each handling user device access and backbone network services. During daily operation, the device rapidly scans the surrounding wireless environment and automatically selects the optimal channel for operation. Automatic link configuration within the base station ensures reliable connectivity between nodes. The device's multi-channel operation fully utilizes both the 2.4 GHz and 5 GHz frequency bands, improving network performance while also avoiding signal interference during large-scale coverage.

[0086] In the fifth step, monitoring data is transmitted to a remote terminal via the MESH network. The terminal user can view high-definition video and data of the transmission line on the monitoring system's display. The device also supports remote control. Users can send commands to the monitoring terminal via the communication controller to start or shut down connected devices and adjust their operating status as needed. This function is particularly useful for remote inspections and emergency monitoring.

[0087] Step 6: MESH base stations offer exceptionally flexible installation and use. By cascading multiple hotspots, network coverage can be effectively expanded. The greater the number of base station hops, the greater the network reach without significantly reducing bandwidth, ensuring robust monitoring of large-scale transmission lines. This device comprehensively optimizes the entire transmission line inspection and fault monitoring process, enabling efficient and reliable remote monitoring.

[0088] The above is only a specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any modifications, equivalent substitutions and improvements made by any technician familiar with this technical field within the technical scope disclosed by the present invention and within the spirit and principles of the present invention should be covered by the scope of protection of the present invention.
