The basis of this product design concept for the CNC system, that is, the aircraft as a controllable system that can be 6-dimensional movement, the acquisition of cameras by the aircraft transported to the appropriate location for data acquisition, passed to the data center for data analysis based on machine vision and deep learning, and then give the final column inspection discriminatory results.
2. The special aircraft for parking lot inspection can be used to carry out inspection operations in the parking lot under the full environment from day to night, and has strong anti-electromagnetic interference capability to ensure the smooth implementation of the inspection process.
3. The aircraft can quickly carry out flying inspection on the car body, roof and underneath the car, reducing the staff's work of climbing high and working low, greatly enhancing the work efficiency, reducing the staff's work intensity and avoiding work hazards.
4. The aircraft adopts advanced visual slam navigation, and is equipped with self-researched navigation functions, real-time detection of the aircraft's spatial location, with the control system to make the aircraft positioning accuracy in the centimeter level.
5. The aircraft is equipped with internal visual obstacle avoidance system, using optical flow self-stabilization, equipped with a variety of monitoring sensors such as air pressure fixed height and ToF sensor fixed height, to ensure the positioning requirements in the listing workshop, and through the depth camera visual collision avoidance system to ensure the safe flight of the equipment, to ensure the normal operational needs and personnel and vehicle safety.
Safety of personnel and environment
6. The aircraft has fewer electrical components, and the probability of failure is lower.
7. The aircraft is equipped with fill light to ensure the normal operation of the vision system in a low light environment and meet the needs of night operation.
8. The aircraft is equipped with a fully enclosed blade protection cover to prevent damage to the body or hitting the wall during operation and other phenomena to strengthen protection safety measures.
9. The aircraft is designed for intrinsic safety, with safety shield, and its own light weight, small size, even if the electrical failure will not cause harm to the equipment.
Collision safety
10. With advanced flight control system, route planning software can set waypoints according to the site environment, and support each waypoint to execute multiple groups of actions, with remote control center, according to the needs of the listing will be stored as route files, in the future automatic inspection tasks at any time to call.
11. The aircraft is equipped with a proprietary 3-axis gimbal, with a controlled rotation range of -135° to 90° (pitch), to meet the work needs of the aircraft on the roof, side and bottom of the vehicle, on the basis of which the AI algorithm will independently compare the target area and the current real-time picture, and accordingly correct the camera shooting angle, thus ensuring that each operation ensures the detection needs.
12. With 10 km map transmission distance, 720p@30fps real-time map transmission quality, and 12 Mbps map transmission maximum bit rate, to ensure the real-time information transfer between the vehicle and the control center.
13. The workstation is equipped with landing point, battery charging and changing device, when the vehicle is low on power or after completing the listed work, it will land on the landing point of the workstation independently and complete battery charging and changing to meet the continuous listed demand.
14. The workstation has flight control and data processing functions, including waypoint planning system, data transfer and storage system, information processing system, status monitoring system, abnormal alarm system, site monitoring system and manual control and other multi-systems.
15. The workstation has a display terminal to collect manual data in the process of listing and inspection to facilitate human-machine interaction operations.
16. The data center uploads the results of the judgment and classification of the inspection content to the cloud computing platform, and with the arithmetic power and big data support of the cloud computing platform, the inspected model, location and inspection content are matched and judged, and the fault points of different classifications are identified through different deep learning algorithms. Different deep learning models are trained according to different car models and locations for faults that often occur at fault points to improve the recognition rate.
17. The cloud computing platform has a generalized deep learning detection model, which can identify and judge foreign objects such as plastic bags, animal carcasses, feces, bottles, pieces of paper and other household items under the car, and can detect the types of foreign objects to improve the recognition rate.
The robot flight inspection system is mainly composed of inspection aircraft, workstation, flight control and data processing center.
1. List inspection aircraft
The aircraft scans the top, side, interior and bottom of the vehicle waiting for inspection position by carrying binocular vision structured light measurement and other technologies, generates 3D point cloud and 2D high-definition images, and can visually inspect the vehicle listed in the parking lot, including deformation, missing, loose fasteners, foreign object invasion, etc., and can realize the dimensional measurement of key components.
Serial inspection vehicle
The aircraft is equipped with a 3-axis camera gimbal, with a controlled rotation range of -135° to 90° (pitch) to meet the needs of the work, on the basis of which the AI algorithm will independently compare the target area and the current real-time picture, according to which the camera shooting angle is corrected, thus ensuring that each operation to ensure the detection needs.
2 Workstation
The workstation is set up in the parking lot, which can quickly and automatically complete the aircraft charging operations. At the same time, the aircraft is parked in the workstation during non-operating hours, always keeping the battery fully charged.
