Power lines stretch for hundreds of kilometers across mountains, rivers, and open countryside, running entirely in the open without any cover. This means that all natural changes and human activities along the route directly affect the conductors and towers. In other words, operations and maintenance personnel are not dealing with a single specific fault, but rather a network of potential hazards spanning the entire line. Currently, the following challenges in power grid monitoring have persisted for a long time:
Damage caused by external forces and accidental damage during construction
These include third-party construction activities such as excavation, lifting, and drilling; illegal fishing; foreign objects entangled in conductors; and unauthorized work near overhead lines. In particular, during construction work conducted directly beneath overhead high-voltage lines, accidental contact by machinery or vehicles, as well as construction workers handling, lifting, or hoisting long metal building materials such as rebar, steel pipes, and scaffolding, can easily result in these materials coming into contact with or bridging the high-voltage lines due to limited visibility and an inability to accurately judge safe distances. The consequences can directly lead to pole collapses, broken wires, short circuits, and circuit breaker trips, and may even result in electric shock accidents. Since these hazards occur unpredictably, traditional patrols are simply unable to detect them in advance.
Conflicts Between Trees and Power Lines and Forests Along Power Lines
Conflicts between trees and power lines often occur in mountainous areas or urban-rural fringe zones. These conflicts manifest as the planting of tall-growing plants such as fast-growing poplars and bamboo within power line protection zones, as well as uncontrolled vine growth. When branches rub against or break and snag on power lines, this can easily lead to broken conductors and electrical discharges; during thunderstorms, this is likely to cause arcing and fires.
Outdoor Power Monitoring Solution
Dingxin Smart Technology’s DX-WPS100-SP7 micro-pan-tilt video surveillance device employs a combined image and video monitoring approach. It supports 360° horizontal and ±90° vertical rotation, providing comprehensive, blind-spot-free coverage across five key areas: channel environments, potential hazard zones, equipment status, work sites, and emergency repairs.
The system integrates edge computing, AI recognition, wireless transmission, and data security technologies. The AI algorithms are trained using deep learning based on a large dataset of power construction images, enabling them to automatically identify construction machinery such as cranes, tower cranes, and excavators, as well as potential hazards like suspended foreign objects, smoke, and wildfires. Upon detecting an anomaly, the system issues real-time alerts without relying on manual interpretation.
At on-site construction sites, the device can also detect violations such as failure to wear a hard hat, failure to wear a red vest or work uniform, failure to fasten a safety harness, smoking on site, and using a cell phone, while simultaneously capturing the violator’s facial image. Upon detecting a violation, the device triggers an audible and visual alarm and supports remote public address announcements, enabling a closed-loop management process directly at the worksite.
Data is transmitted to a designated platform via a 4G-APN private network SIM card, allowing the monitoring center to access real-time footage from any tower at any time. This enables real-time oversight of the operational status of all equipment along the line and the environmental conditions of the transmission corridors, significantly reducing the frequency of field inspections and substantially lowering labor, vehicle, and time-related maintenance costs.
Suitable for implementation in a variety of scenarios
Unlike conventional surveillance equipment, which suffers from high power consumption, limited power supply options, and poor environmental adaptability, the DX-WPS100-SP7 micro PTZ video surveillance device features an ultra-low-power hardware design combined with a wide-voltage input solution. It is perfectly suited for outdoor environments without access to mains power and is powered by a solar energy storage system, offering convenient installation and deployment along with broad adaptability.
In addition, our micro-gimbal video surveillance devices have undergone professional electromagnetic compatibility optimization and feature exceptional interference resistance. They can operate stably in the complex electromagnetic environments of power transmission lines—where strong radiation and high levels of interference are present—ensuring smooth video transmission, reliable recognition algorithms, and uninterrupted device operation, thereby mitigating interference issues caused by high-voltage power environments. Leveraging superior hardware performance and environmental adaptability, the system provides comprehensive coverage across all power scenarios—including transmission, distribution, and substation operations. It is widely deployed in various power projects, such as online monitoring of high-voltage transmission lines, security management of distribution network corridors, environmental monitoring around substations, construction site supervision for power infrastructure, and routine monitoring of remote power facilities. With its high versatility and practicality, the system meets the intelligent upgrade needs of diverse power operation and maintenance projects.
