JOUAV recently announces the release of its innovative drone solutions, CW-15LiDAR and CW-15X UAV Hangar, which can carry out inspection missions more efficiently and fully automatically.

Drone inspections are now being conducted by many industries that require visual inspections as part of their maintenance procedures. Using drones to collect visual data on the condition of assets helps inspectors increase efficiency and avoid putting themselves in harm's way. To provide users with a more convenient and efficient operating experience, JOUAV unveils a brand-new LiDAR drone system and drone hangars for automatic inspections.

CW-15 LiDAR system with 1430m detection range

JOUAV's CW-15 LiDAR system has broken through the technical difficulty of carrying a long-range LiDAR system on a 15kg payload electric UAV. The LiDAR is deeply integrated with the drone system and has been successfully applied to digital mines, energy inspection, smart city, rail transportation, and other professional fields, providing users with a more convenient and efficient operating experience.

With a weight of only 2.7kg (including the camera) and a maximum range of 1430m, the JoLiDAR-120 LIDAR system offers an ultra-wide field of view of 100° and an ultra-high data acquisition rate of up to 1.8 million points/second. It combines laser point cloud data and visible light images to generate a high-density true color point cloud with a vertical accuracy better than 2cm without GCP.

The measurement beam can be scanned continuously from front to back in three different directions: forward +10°, vertical downward, and backward -10°, effectively improving the integrity of the data. The CW-15 equipped with JoLiDAR-120 LIDAR has an effective operating time of up to 100 minutes, which is suitable for large areas and high-precision data acquisition.

The LiDAR system is deeply integrated with the flight control system, and the protocols are interoperable. The LiDAR parameter setting can be completed through the JOUAV FlightSurv ground station software, without the need to open the scanning on the ground in advance.

The drone automatically starts data acquisition before entering the survey area, reducing data redundancy in non-operational aspects such as ground preparation, takeoff and climb, heading to the survey area and returning to land, improving the efficiency of internal data processing and extending the service life of the LiDAR.

During the flight, the working status of LIDAR temperature, GNSS, inertial guidance, data storage, etc. can be monitored in real-time to ensure the safe and effective operation of the LIDAR system.

Real application of CW-15LiDAR in Fengxin County

Fengxin County, a county located in the northwestern part of China's Jiangxi Province, has a forest coverage rate of 64.46%. This area is particularly suitable for wind farm construction because of its rich wind resources, stable wind direction and windward slope, small seasonal changes, and no extreme weather. Guohong New Energy Co. used CW-15LiDAR to collect 1:2000 point cloud results from the wind farm site in Fengxin County.

"The survey area is mostly mountainous, with great height differences of more than 1200 meters, dense vegetation cover, and windy weather all year round, leading to a significant increase in both risk and data collection difficulties," said Evan Wang, an engineer at the Fengxin wind farm project.

In this mapping project, they divided the survey area into three areas, low, medium, and high, according to the altitude. CW-15LiDAR flew 6 flights, including 2 flights in the high area, 3 flights in the middle area, and 1 flight in the low spot.

"Using the CW-15LiDAR, the entire data collection workflow itself took only 5 hours - a process that could easily have taken several days with traditional surveying methods. Under the large altitude difference conditions in the survey area, our engineers obtained a vertical accuracy was only 10.4cm," commented Evan.
