Description

Technical Field

[0001] This invention belongs to the field of grounding wire management technology, specifically relating to an intelligent grounding wire management platform based on the Internet of Things and Beidou technology. Background Technology

[0002] Currently, the management of grounding wires mainly relies on regulations, making it difficult to achieve real-time management of their status. Without real-time knowledge of the grounding wires' condition, potential safety hazards may arise for the power system. Furthermore, the location and status of grounding wire connections during power construction and maintenance cannot be monitored in real time. It is impossible to determine whether grounding wires have been properly connected, whether they meet safety regulations, and especially whether they have been promptly removed, posing significant safety risks.

[0003] At present, most domestic and foreign research only focuses on the technical solutions of the software or hardware parts of the grounding wire, lacking systematicness and integrity, and cannot fundamentally solve the problem of temporary grounding wire safety monitoring. Specifically, it is manifested in the following ways: (1) Non-standard grounding wire management: There are problems with the maintenance, testing, storage and hanging / removing of grounding wires. In addition, traditional grounding wire management lacks intelligent management methods and is not suitable for the current management needs of substations; (2) Insufficient coordination between grounding wires and other equipment: During the power supply and closing process of substations, the grounding wire system and the anti-misoperation interlocking system, monitoring system and other systems cannot cooperate correctly with each other, resulting in problems such as untimely information transmission and uncoordinated operation, which can easily cause power system misoperation accidents and reduce the safety and reliability of the power system. Therefore, how to solve the problem of grounding wire connection reliability, accurately identify the geographical location of the grounding wire and whether the grounding wire is correctly connected, and realize the real-time monitoring of the grounding wire during the construction of power lines is still an important link in power safety management.

[0004] To address the aforementioned issues, it is essential to develop an intelligent grounding wire management platform based on the Internet of Things and BeiDou technology. Summary of the Invention

Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the platform composition of the present invention. Detailed Implementation

[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown, the present invention provides an intelligent grounding wire management and control platform based on the Internet of Things and Beidou technology, including an intelligent sensing layer, a network transmission layer, a platform core layer, and a business application layer.

[0020] The intelligent sensing layer includes a smart grounding wire and a smart grounding cabinet. The smart grounding wire collects the precise geographical location and status of the grounding wire in real time through multiple built-in sensors, while the smart grounding cabinet collects the connection / removal status and cabinet status of the grounding wire in real time through built-in status sensors.

[0021] The smart grounding wire integrates a multi-mode positioning unit, a status sensing unit, a wireless communication unit, and a power and power management unit. The multi-mode positioning unit includes a BeiDou satellite positioning module (BD) and a Landslide Protection (LBS) module, ensuring real-time and accurate location information transmission regardless of whether it's in open outdoor areas or complex urban environments. The status sensing unit uses a mechanical sensor or proximity switch to determine if the grounding wire is reliably connected to the power equipment (grounding status) and to detect when the grounding wire has been removed from the equipment but not returned to the grounding cabinet (retrieval / in transit status). The wireless communication unit integrates a 4G / 5G or NB-IoT communication module to upload the collected status and location data to the platform in real time. The power and power management unit uses a high-performance lithium battery and automatic power management technology, entering a low-power sleep mode during non-communication periods to significantly extend battery life, and also features power self-checking and reporting functions.

[0022] The intelligent grounding cabinet includes an on-site identification unit, an automatic charging unit, a cabinet door status monitoring unit, and a local control and communication unit. The on-site identification unit uses RFID, Bluetooth beacons, or pressure sensors to automatically identify and record the grounding wire's return status or its on-site / off-site status. The automatic charging unit provides contact or wireless charging for the intelligent grounding wire, ensuring it is always fully charged. The cabinet door status monitoring unit uses a high-definition camera to monitor the cabinet door's opening and closing status and records the time of grounding wire access and return. The local control and communication unit is responsible for data aggregation from the grounding cabinet and communicates with the platform layer via a local area network or wireless network.

[0023] The network transmission layer includes communication base stations and communication relay stations, which together form a hybrid wireless network covering all operational areas.

[0024] Among them, the communication base station is used to build a core wireless communication network in fixed areas such as substations and work area office buildings. The wireless data transmission adopts LoRa, Zigbee or dedicated wireless technology to communicate with the smart grounding wire and intelligent grounding cabinet within the range. The power supply is connected to the mains power to ensure continuous and stable operation.

[0025] Among them, the communication relay station is used to extend the network coverage and solve the communication problems in remote mountainous areas, underground tunnels and other signal blind spots. The wireless relay receives data from the perception layer and forwards it to the communication base station or directly uploads it to the platform layer in a multi-hop manner. The power supply integrates solar panels and high-capacity batteries to achieve energy self-sufficiency, adapt to environments without mains power, and intelligently manage the charging of solar panels and the discharging of batteries to ensure continuous operation in rainy weather.

[0026] The core layer of the platform includes a monitoring host and monitoring software. The monitoring host can be deployed locally or in the cloud. The monitoring host, which provides stable and efficient computing services, is used to run the monitoring software. It processes, stores and analyzes all incoming data through database and information processing technologies, and intuitively displays the real-time status, location and historical trajectory of the grounding wire through a graphical interface, realizing panoramic monitoring, intelligent alarm and electronic ledger management.

[0027] The monitoring software includes a real-time status monitoring unit, a graphical display unit, an alarm and error prevention unit, and a data traceability unit. The real-time status monitoring unit dynamically displays three states for each grounding wire: grounding status is highlighted in red, with the connection position precisely located on the map; "retrieved / in transit" status is displayed in yellow, indicating it has been removed but not yet returned, with real-time tracking of its movement; and "ready for use / stored" status is displayed in green, indicating it has been safely stored in the designated grounding cabinet. The graphical display unit includes a 2D / 3D map engine and a substation / line single-line diagram. The 2D / 3D map engine integrates BeiDou mapping, intuitively displaying the location distribution of all grounding wires, personnel, and vehicles. The substation / line single-line diagram directly connects and displays grounding wires on the main electrical wiring diagram, perfectly corresponding to the site conditions. The alarm and error prevention unit provides alarms for illegal displacement, unauthorized operation, live grounding wire connection, and missing grounding wires. The data traceability unit provides a complete electronic ledger recording the entire process of each grounding wire's receipt, transportation, connection, removal, and return, facilitating rapid backtracking.

[0028] Database and information processing technologies provide database storage and intelligent analysis for the platform layer. The databases include relational databases (such as MySQL and PostgreSQL, used to store structured data such as device information, user permissions, and operation records) and spatiotemporal databases (such as PostGIS, used for efficient storage and management of massive amounts of grounding wire location trajectory data). Intelligent analysis refers to the real-time processing of incoming IoT data streams through a data processing engine, including filtering, aggregation, and event triggering.

[0029] The business application layer is used to provide the information processed by the core layer to operation and maintenance and dispatch personnel through the web and mobile APP, and to link with the operation and maintenance department and dispatch system to directly integrate the grounding wire status into the safety production process, providing key data support for operation ticket execution, safety supervision and decision-making, and ultimately realizing lean management of the entire life cycle of the grounding wire.

[0030] The business application layer includes a multi-terminal access unit, an operations and maintenance (O&M) department interface, and a dispatch system interface. The multi-terminal access unit provides a web-based (PC) or mobile app (smartphone / tablet) interface for O&M personnel, dispatchers, and field supervisors to view and manage grounding wires anytime, anywhere. The O&M department interface pushes grounding wire status and alarm information to the O&M department's mobile inspection system and safety monitoring platform in real time. The dispatch system interface interacts with the power dispatching master station system (SCADA / EMS) to provide dispatchers with accurate information on on-site safety measures, assisting in the completion of power outage and restoration procedures, and fundamentally preventing serious accidents caused by powering on with the grounding wire connected.

[0031] In summary, the intelligent sensing layer of this invention serves as the data source, collecting the location, status, and identity information of the grounding wire on-site, and uploading the data stream to the network transmission layer. Then, the network transmission layer receives the data from the sensing layer and forwards it to the platform core layer. The platform core layer then receives the data from the transmission layer, is responsible for processing, storing, and analyzing the data, and provides visualization and intelligent alarms. After processing, the information is pushed to the application layer. Finally, the business application layer provides the processed information to different users (operations and maintenance, scheduling) and business systems in various forms, realizing a closed loop of security management.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
