I. Requirements Analysis

In recent years, the probability of power line tripping and forced outages caused by human factors, external damage, and theft has been on the rise. Therefore, curbing accidents caused by human factors and ensuring the safe operation of the power grid have become urgent issues for line management and maintenance units. Our company's developed online laser-based anti-external damage monitoring device for transmission lines can completely resolve the inability to promptly detect external damage from large construction machinery during illegal construction operations and theft issues. This significantly reduces power outage incidents caused by external damage and theft, minimizes the resulting economic losses, and enables more rational and effective personnel allocation to ensure the safe operation of power lines.

II. Working Principle

The laser-based anti-collision monitoring system for transmission lines employs dual detection and protection mechanisms: laser detectors mounted on towers and AI video surveillance. Primary protection: When the tower-mounted laser detector detects a crane exceeding height limits, it immediately triggers audible and visual alarms, signaling proximity to high-voltage lines and halting operations to prevent contact. Simultaneously, the alarm signal is transmitted via 5G/4G wireless to the central platform. Platform software can notify the dispatcher, while real-time video can be activated via mobile or computer to view the scene. Real-time voice announcements can also be made to promptly halt dangerous operations. Secondary Protection: Tower-mounted AI video cameras detect crane intrusion and immediately initiate recording, signaling unauthorized entry. The monitoring center issues real-time voice alerts to promptly halt hazardous operations.

III. Features and Functions

1. Basic configuration for laser anti-tampering system: Master control unit, video monitoring unit, laser anti-tampering monitoring unit, communication unit, power supply unit, audible-visual alarm, mounting brackets, and auxiliary materials.

2. Laser Scanning Detection Function: Revolutionizing traditional physical anti-collision protection, this system employs high-precision horizontal laser scanning at a safe distance below power lines to form a horizontal protective plane. Should a crane approach from below or the side and its upper structure contact the laser plane, an alarm is immediately triggered. This activates video recording and synchronized alerts in the crane cab, warning the operator of potential high-voltage contact. Unlike image recognition algorithms, laser scanning offers extended coverage distance and timely, precise responses. It addresses the limitations of image recognition, which may exhibit partial errors or false alarms, making it the most reliable and accurate detection method among current external intrusion prevention technologies.

3. Front-end AI video recognition and analysis capabilities enable comprehensive monitoring of the entire conductor corridor. Upon detecting foreign object intrusion, the system automatically triggers the anti-tampering monitoring host to capture photos and record video. Simultaneously, it provides 360° surveillance coverage of the entire conductor corridor.

4. Real-time video monitoring capability with resolution ≥1080P, enabling live video feeds of transmission line corridors, tower foundations, and potential hazard sites.

5. Remote loudspeaker with voice broadcast and audible-visual alarm functionality, enabling remote announcements while simultaneously triggering audible-visual alarms upon detecting objects exceeding height limits.

6. Can be linked to the crane proximity warning system. When the laser scanner detects a crane entering the danger zone, it immediately triggers the crane proximity warning device to sound an alarm, alerting the operator to cease operations.

7. Supports nighttime detection capabilities, enabling seamless monitoring of transmission line operations during rainy or foggy conditions while maintaining 24/7 operational readiness.

8. The device shall be powered by solar energy and lithium batteries, utilizing industrial-grade power management modules and an efficient solar-battery power management solution to ensure reliable system operation.

9. Supports full network compatibility with 4G/5G/Wi-Fi functionality;

10. Supports standard grid protocols and integrates with internal network platforms.
