Mountain transmission lines stretch across rugged terrain with large spans, high altitude differences, and dense forest occlusion, resulting in widespread public network gaps and complex electromagnetic environments. Traditional manual on-foot inspection incurs high labor costs, poses significant safety risks for high-altitude operations, and has limited coverage, making it difficult to quickly detect hidden hazards such as damaged insulators and foreign object entanglement, failing to meet the digital operation and maintenance needs of modern power grids.

The drone swarm MESH ad hoc network inspection solution, built on DJHW/HZ Series Airborne Ad Hoc Network Devices + DJHW/JZ Series Ground Stations, upgrades mountain power grid inspection across operation modes, communication links, and remote management through multi-drone formation operations and aerial three-dimensional networking, transforming inspection from manual on-site investigation to remote visual intelligent monitoring.

1. Operation Mode: Multi-Drone Formation Cluster Inspection for Expanded Coverage

The solution adopts a 4-5 drone synchronous takeoff and collaborative cluster inspection mode to overcome the limitations of short range and narrow coverage of single-drone operations:

• Each industrial drone is equipped with a DJHW/HZ Series Ad Hoc Network Terminal + HD Inspection Pod, which captures high-definition images and detailed data of conductors, hardware, towers, and insulators in real time;

• Multi-drones simultaneously inspect long-distance mountain lines in segments, enabling large-scale synchronous operations and drastically reducing the inspection cycle for entire lines;

• All site footage is aggregated to the ground command terminal in real time, achieving full-line hazard detection without blind spots.

2. Core Communication Solution: MESH Decentralized Ad Hoc Network Eliminates Mountain Disconnections

Traditional public network video links are prone to lag and disconnection due to mountain and forest occlusion, the biggest bottleneck in mountain drone inspection. The DJHW/HZ Series Ad Hoc Network Devices in this solution adopt a decentralized MESH distributed networking architecture:

1. Auto-networking on Power-On: Multiple airborne nodes quickly establish a three-dimensional wireless communication network in the air, independent of base stations or fixed public networks;

2. Multi-hop Relay Self-healing: Each device acts as both a terminal and a router. If a drone is blocked by mountains or experiences signal fluctuations, the network automatically optimizes routing paths to relay data;

3. Full-link Stable Transmission: Completely resolves industry-wide issues such as frozen frames, data packet loss, and command delays in deep mountain blind spots.

3. Ground Command Center: DJ/JZ Ground Station for Centralized Transceiving and Remote Coordination

The DJHW/JZ Series Ground Station serves as the communication and command core of the entire inspection system:

• Unifies access to all networking signals from the aerial swarm, centrally receiving, decoding, and storing front-end HD video and inspection data;

• Leverages the device's high-bandwidth, low-latency transmission advantages to synchronize multiple inspection streams on a large screen with smooth, artifact-free playback;

• Managers can remotely view full-line conditions in the control room without entering the mountains for on-site investigation.

4. Four Core Advantages of the Solution

✅ Cluster Efficiency: Multi-drone synchronous operations increase inspection efficiency for long-distance mountain lines by several times compared to manual methods, drastically shortening inspection periods

✅ Uninterrupted Communication: MESH ad hoc network operates independently of public networks, enabling stable HD data backhaul even in signal-dead areas like forests and valleys

✅ Remote Monitoring: Centralized visual monitoring at the backend instantly identifies hazards such as line damage, tree barriers, and external construction

✅ Cost Reduction & Risk Mitigation: Reduces extensive field labor input and eliminates safety risks for inspectors working at height or in remote mountains

5. Application Scenarios

• Routine inspection of high-voltage/ultra-high-voltage transmission lines in high-altitude mountainous areas

• Fault investigation of lines in remote forests and valleys during flood seasons or after disasters

• Periodic hazard surveys of large-scale long-distance pipelines

• Aerial survey for acceptance of newly built mountain power grid lines

6. Conclusion

The complete drone swarm ad hoc network inspection solution, built on DJHW/HZ Airborne Ad Hoc Network + DJHW/JZ Ground Station, forms a full closed-loop intelligent inspection chain: Front-end Cluster Collection → Aerial MESH Multi-hop Transmission → Ground Centralized Analysis → Backend Remote Judgment.

It not only solves the data backhaul challenges caused by public network gaps and severe occlusion in mountainous areas but also achieves large-scale efficient inspection through formation operations, helping power grid operation and maintenance reduce costs and increase efficiency, and accelerating the digital and intelligent transformation of mountain power grid operation and maintenance.
