Power transmission lines are mostly distributed in remote mountainous areas, hills and wilderness with complex terrain. These areas are generally covered by public network signal blind spots, becoming a major pain point for intelligent power transmission monitoring.

High-definition video and broadband data collected by drones cannot be transmitted back in real time due to the lack of stable communication links. It makes it difficult for backend staff to grasp the line operation status on time, delays hidden danger detection, and restricts the intelligence level and efficiency of power transmission inspection.

To solve this industry challenge, the communication solution for unmanned power transmission monitoring areas centered on DJHW/JC-33-100M-C ad hoc network device has been launched. It builds a full-link closed-loop architecture of Front-end Collection — Multi-hop Relay — Public Network Access — Solar Power Supply, realizing stable and efficient backhaul of broadband data in unmanned areas, and providing solid communication support for smart power transmission inspection.

1. Solution Core Objectives

Break through the communication bottleneck of unmanned power transmission monitoring areas, solve the problem of real-time backhaul of high-definition broadband video data, and build an integrated full-link communication system of Front-end Collection - Intermediate Transmission - Back-end Presentation.

It promotes the transformation of power transmission inspection from traditional periodic manual inspection to a new model of all-weather online perception and real-time visual management.

2. Four Core Links | Build a Complete Communication Closed-loop

2.1 Data Collection & Initial Transmission

High-definition cameras deployed on site capture the operating status of power transmission facilities such as conductors, insulators and hardware in real time, and record potential environmental risks including surrounding construction, vegetation overgrowth and foreign object entanglement.

The collected high-definition video broadband data is transmitted to the DJHW/JC-33-100M-C ad hoc network device in real time. As the core communication terminal of the solution, it features powerful signal receiving and forwarding capabilities, efficiently carrying high-bandwidth video transmission and laying a solid foundation for long-distance relay transmission.

2.2 MESH Multi-hop Networking & Relay Transmission

Aiming at no public network coverage, signal occlusion and long transmission distance in mountainous and woodland areas, the solution adopts MESH chain ad hoc network technology. Multiple DJHW/JC-33-100M-C devices realize wireless multi-hop relay transmission.

MESH ad hoc network is centerless, self-networking, self-healing and multi-hop forwarding. Each device acts as both a terminal and a routing node, automatically networking and forwarding data mutually. It establishes a chain communication link in non-line-of-sight complex environments, extending monitoring data step by step to transmission towers with public network coverage, and thoroughly solving signal attenuation, occlusion and long-distance backhaul difficulties in unmanned areas.

2.3 Flexible Public Network Access & Background Real-time Monitoring

After data is transmitted to towers with network coverage via multi-hop relay, two flexible access modes are supported:

4G/5G coverage areas: Access public network quickly through 4G/5G CPE router;

Wired accessible areas: Direct network cable access for more stable transmission.

Data is forwarded to the backend monitoring center in real time. Managers can view all drone inspection video feeds on the central control screen, promptly identify line damage, foreign object winding, external construction intrusion and tree barrier hazards. It realizes remote visual management, reduces manual inspection intensity and avoids field operation safety risks.

2.4 Solar PV Energy Storage Power Supply | 24/7 Uninterrupted Operation

Unmanned wild power transmission areas have no municipal power supply, which is a key difficulty for long-term stable device operation.

The solution deploys solar photovoltaic power supply system on transmission towers, equipped with energy storage batteries to provide stable power supply for DJHW/JC-33-100M-C ad hoc network devices and cameras.

It automatically switches between energy storage in sufficient sunlight and power supply at night or on cloudy days, adapting to harsh outdoor weather. The system maintains 24/7 uninterrupted operation, avoiding monitoring suspension and data loss caused by power outages.
