The use of paper records for tracking grounding wire usage is time-consuming and labor-intensive, and poor management often leads to the process becoming mere formality.
The inability to collect connection status leads to serious safety hazards such as incorrect removal, missed removal, incorrect attachment, and missed attachment, posing significant risks to both personnel and equipment safety.
Grounding wire connection points are untraceable, leading to potential hazards such as entering the wrong bay.
The retrieval and usage records of grounding wires lack digital methods, making it impossible to maintain electronic records, which creates challenges for performance evaluation and traceability.
Establish a WAPI network in the substation to achieve full signal coverage in the area, and deploy a wireless intelligent grounding wire management system. This ensures safe access to the wireless network and enables real-time data collection of grounding pile status, transforming the original “virtual remote signal” of the grounding pile in the microcomputer anti-misoperation system into a “real remote signal.” This avoids unnecessary travel during grounding wire installation and removal and eliminates the risk of misplacing or failing to remove grounding wires. An intelligent grounding wire cabinet is deployed to ensure the proper storage of grounding wires and manage their usage based on ticket issuance.
Ground wires retrieved based on tickets
The ground wires are locked using a locking device inside the intelligent ground wire cabinet. Only after the user unlocks the ground wire based on the operation task can the wire be retrieved, and the retrieval record is generated.
Ground wire status awareness
The ground wire detection device automatically detects the ground wire connection status and transmits the data back. Users can view the ground wire status in real time through the system software.
Real-time position tracking
Once the ground wire head is connected, the system recognizes the intelligent ground pile code and transmits the current connection location in real time over a wireless network. Users can view the ground wire location in real time through the software.
Traceable records
After the work task is completed, the ground wire usage record is automatically generated and saved. Users can trace the entire usage record of the ground wire through the system software.

基于NB-IoT的智能接地线管理系统在抽水蓄能电站的应用
抽水蓄能电站电气设备日常检修需要频繁使用临时接地线,但目前,绝大多数抽水蓄能电站临时接地线状态采集主要依靠人员自觉记录,存在误挂、漏拆的风险。
The substation WAPI network has been established to achieve full signal coverage within the station. The wireless intelligent grounding wire management system has been deployed, securely connected to the wireless network, enabling real-time collection of grounding stake status. This transforms the original microcomputer-based anti-misoperation system's "virtual remote signal" for grounding stakes into a "real remote signal," preventing unnecessary operations during grounding wire installation and removal, and eliminating errors such as incorrect attachment or missed removal of grounding wires. An intelligent grounding wire cabinet is deployed to ensure the proper storage of grounding wires and manage their usage based on ticket issuance.
With "safety and efficiency" as the goal, and "business collaboration" and "data integration" as the core, based on the requirements of one-click sequence control, intelligent substations, and centralized control station construction, the system adheres to the new-generation architecture of substation secondary products that are autonomously controllable and compliant with information security standards. It relies on new technologies such as "big data, cloud computing, IoT, AI, and intelligence" and introduces innovative applications such as intelligent sensing, intelligent ticketing, intelligent verification, and intelligent maintenance. This expands anti-misoperation control from primary equipment operations to secondary equipment operations, maintenance tasks, and O&M activities, achieving comprehensive anti-misoperation safety management and control.
Based on microcomputer anti-misoperation technology, the safety management and control system for substation operation and inspection targets every aspect of integrated O&M workflows, including switching, maintenance, and repair operations. Through process refinement and system applications, combined with existing innovative technologies, it establishes a platformized, networked, and intelligent substation O&M safety management and control system. This platform fully covers safety control for O&M and repair across multiple disciplines, effectively improving work efficiency, reducing operational costs, and enhancing power safety production levels.
JOYO advanced minicomputer-based anti-misoperation integrated operation system has evolved through three generations of substation microcomputer anti-misoperation technology, accumulating experience from over 40,000 substations. By introducing innovative design concepts and leading key technologies, it serves such functions as simulated operation, anti-misoperation interlocking, and operation ticket management. The system utilizes a computer key to unlock on-site equipment, receive, and transmit data, while various locks are used to interlock on-site equipment, preventing electrical misoperations and ensuring safe and controllable disconnector operations.
Substations, power plants, and industrial and mining enterprises' tool rooms store various safety tools and equipment, including insulating gloves, insulating shoes, safety helmets, voltage detectors, and temporary ground wires. Due to the large number, safety tools are placed in disorder. As a result, a lot of time needs to be spent counting them during inspections. The management practices are outdated . The UT-7710 series intelligent safety tools and equipment management device can electronically identify safety tools and equipment, enabling online detection and intelligent lifecycle management of safety tools and equipment. The safety tool management device can be used independently or used with other systems to achieve advanced management of safety tool .
The UT-050 series intelligent unlocking key management machine uses electronic sealing technology and mobile internet technology to standardize the authorization of all unlocking keys and automatically store usage records. These technical measures ensure the proper management and use of unlocking tools (keys). It accurately records details such as the applicant, approver, reason for unlocking, key retrieval, and return, and enables key monitoring, remote control, and directional unlocking, eliminating human errors, standardizing the management of unlocking tools (keys), and ensuring the safety of on-site personnel as well as the O&M safety of power grid equipment.
Currently, many accidents in transmission and distribution lines are caused by grounding wire issues. While negligence during operation is one factor, the more significant reason is the lack of effective management of grounding wires in transmission and distribution lines. This solution utilizes intelligent monitoring devices installed on grounding wires to enable real-time data collection and uploading of grounding wire connection status and location. Through cloud services and a mobile app, it enables remote monitoring and management of grounding wire storage and usage information. An intelligent grounding wire cabinet is deployed to ensure the proper storage of grounding wires and manage their usage based on ticket issuance.
