Disaster recovery backup vehicle-mounted emergency charging method for routing inspection UAV (unmanned aerial vehicle) motorcade

Abstract

The invention relates to a disaster recovery backup vehicle-mounted emergency charging method for a routing inspection UAV (unmanned aerial vehicle) motorcade. The method comprises the steps that an intelligent charging circuit board controls a storage battery pack to charge a UAV lithium battery through a DC / DC charging module of the intelligent charging circuit board when a vehicle is moving, and the storage battery pack carries out the charging of 220 AC equipment carried by a disaster recovery backup emergency worker at the same time through a DC / AC module; the intelligent charging circuitboard controls a vehicle-mounted generator to charge the UAV lithium battery through the AC / DC module and the DC / DC charging module of the intelligent charging circuit board when the vehicle is parked on a disaster recovery backup site, and the vehicle-mounted generator charges the storage battery pack at the same time through the AC / DC module; the intelligent charging circuit board controls thestart of a fan when the internal temperature of a cabinet is detected to be greater than a threshold value or there is fire in the cabinet. The method effectively improves the utilization efficiency of the UAV battery, greatly improves the endurance of an UAV, greatly enlarges the routing inspection range of the UAV, and plays an important guarantee role in the UAV routing inspection after diasters.

Description

technical field [0001] The invention relates to a vehicle-mounted emergency charging method for disaster recovery of a fleet of inspection drones. Background technique [0002] With the rapid development of the national economy and power system, the scale of the power grid is also expanding. In recent years, the coverage area of ​​overhead transmission lines in my country has become wider and wider. It is estimated that by 2020, the total mileage of transmission lines will reach 1.59×10 6 km, but it should be noted that more than 60% of these lines are located in mountainous areas. The impact of the field environment on the lines is mainly reflected in the proneness to broken strands of wires, corrosion of insulators, broken poles and towers, and insufficient safety distances for line corridors. and other equipment defects or channel safety hazards. If these hidden dangers cannot be discovered and dealt with in time, serious accidents may occur, threatening the safety and...

Problems solved by technology

[0004] The UAV needs to rely on the battery to provide flight power when patrolling (inspecting). Currently, the battery capacity of the UAV is only for cruising for about 15 minutes. When the battery is exhausted, the UAV needs to fly back to recharge. Hour

In addition, the charging life of the battery of the drone is limited, and the battery cannot be fully charged during normal maintenance. Generally, it is charged before the inspection task is confirmed, and the inspection is started after the charging is completed.

This working mode has some problems in actual work. One is that there is often no battery charging condition in the field. If you want to conduct a long-term inspection, you need to provide multiple spare batteries, which is costly and limited in flexibility; If you need to go out for inspection in case of emergency, the battery must be fully charged before starting, and the time arrangement is greatly restricted
