In the fields of power inspection, forestry monitoring, border inspection and other fields, higher requirements are put forward for the endurance and inspection functions of drones. This solution takes gasoline-electric hybrid technology as the core, deeply optimizes the configuration of energy management and inspection systems, and creates a professional inspection drone suitable for long-distance and long-term operations to meet the needs of efficient inspections in complex scenarios.

1. High-efficiency petrol-electric hybrid power system

(1) Upgrading of petrol-electric hybrid architecture

use Intelligent series hybrid system , consisting of a high-power-density aviation heavy-fuel engine and a large-capacity, high-energy-density lithium battery pack. As the power generation unit, the engine is a 4-stroke turbocharged model with a maximum power of 150kW, which can continuously and stably generate electricity to charge the battery pack. ； As the power output unit, the lithium battery pack uses ternary lithium batteries with a capacity of 200Ah to ensure instantaneous high power output. Through the intelligent energy management system, the engine and battery pack work together. During the cruising phase, the engine generates electricity under optimal working conditions, and excess power is stored in the battery. ； Under acceleration, climbing and other working conditions, the battery pack provides auxiliary power to improve power performance.

(2) Power system energy saving optimization

  1. Efficient transmission design : Adopting a direct-drive transmission structure to reduce transmission components and energy loss, the transmission efficiency is increased to 92%. At the same time, the matching of motors and propellers is optimized, and a dedicated low-speed, high-torque motor is selected, paired with a large-diameter, low-speed propeller, to reduce air resistance during flight and improve propulsion efficiency.

  1. Intelligent power generation control : Real-time adjustment of engine speed and power generation based on flight status and battery power. When the battery power is higher than 80%, the engine automatically reduces the speed and enters low-power power generation mode. ； When the battery power is lower than 20%, the engine speed will be increased to increase power generation, giving priority to ensuring flight safety.

At the same time, it supports custom target recognition models, and users can train specific target recognition algorithms according to actual needs.

  1. Real-time data transmission : Adopting dual links of 4G/5G communication and satellite communication to ensure that inspection data can be transmitted to the ground control center in real time and stably under different network environments. Supports the transmission of multiple types of data such as high-definition video streams, 3D map data, and inspection reports.

4. Application scenarios

  1. Electric power inspection : In the vast transmission line area, long-distance autonomous inspections can be carried out to quickly discover line faults and equipment hazards. Compared with traditional manual inspections, the efficiency is increased by more than 80%.

  1. forestry monitoring : Conduct long-term inspections of large areas of forest to promptly detect problems such as forest fires, pests and diseases, and provide strong support for forestry resource protection.

  1. border patrol : In border areas with complex terrain and harsh environment, long-term and large-scale patrols can be realized, border dynamics can be monitored in real time, and national security can be ensured.
