/PRCWT/Guangzhou, July 27, 2023——Forklifts play a vital role in the logistics and warehousing industry and are widely used in all walks of life. However, safety accidents caused by the blind field of visual field of traditional forklift trucks are still occurring frequently.
The forklifts we see are usually 360° "sunroofs", but in fact there are still many areas that are beyond the driver's field of view. On the one hand, these blind areas are caused by the structure of the forklift truck itself: the two lifting cylinders and four bearing places in the front and rear of the forklift truck will cause the driver to partially block the line of sight; On the other hand, the high stacking of goods will block the driver's field of vision, which will also lead to a blind field of vision; In addition, at the corner of the road, the entrance and exit, will form different degrees of blind areas. Once there are pedestrians, vehicles and other obstacles in the blind area, it will directly lead to a blind area crash, which will cause cargo damage and lead to casualties.
With the evolution of warehouse automation, some traditional forklifts are gradually replaced by unmanned forklifts, and more advanced unmanned forklift manufacturers usually install some sensors on the vehicle body to act as its "eyes" to help the forklift identify road conditions information and make up for the pain points of low safety of traditional forklifts.
However, most manufacturers of unmanned forklift trucks on the market usually only install a laser radar at the top of the forklift truck for navigation, positioning and detection of surrounding obstacles. Due to the limitation of the field of view Angle, there are still undetectable visual field blind areas in the low parts of the vehicle body. In order to detect low obstacles around the car body, and taking into account the cost problem, individual manufacturers will also install two single-line lidar on both sides of the bottom of the forklift truck, however, single-line lidar can only detect plane information, it is difficult to accurately detect the distance of irregular obstacles, goods fall, etc., especially at the turn, there is still a high safety risk.
· All-round three-dimensional safety protection, the cost of the whole machine is still controllable
In view of the safety hazards existing in the current market of unmanned forklifts, the multi-line LiDAR 3D SLAM unmanned forklift launched by Leum Intelligent relies on the strong advantages of Leum intelligent in the LiDAR industry, equipped with a number of high-performance LiDAR, providing a full range of three-dimensional perception for unmanned forklifts, fully guaranteeing safe operation.
Laser God intelligent multi-line LiDAR 3D SLAM unmanned forklift truck is equipped with a maximum of 8 self-developed and self-produced LiDAR for the reconstruction of three-dimensional environment, pallet identification and safety protection, and the cost of the whole machine is still super competitive.
Among them, "CH32R ultra-wide Angle blind Lidar" and "C32W large field of view mechanical LiDAR" are two professional blind liDAR designed for all kinds of mobile robots, aiming to provide a broader field of view for unmanned vehicles such as unmanned forklift trucks, realize three-dimensional protection, and ensure driving and operation safety.
·CH32R ultra-wide-angle blind laser radar
The ultra-wide-angle blind Lidar CH32R is placed on the top of the unmanned forklift, and the ultra-large field of view of 360°(H)x90°(V) can fully detect low objects within the range of 120 meters (at 70% reflectivity), making up for the blind field of vision around the vehicle. The dot frequency of up to 1.28 million dots per second and the horizontal resolution of 0.09° ensure the clarity and accuracy of small obstacles detected.
·C32W large field of view mechanical LiDAR
The large field of view mechanical Lidar C32W can be inverted on the left and right sides of the bottom of the forklift truck, and the 360°(H)x70°(V) large field of view can focus on scanning low objects in the range of 120 meters below (at 70% reflectivity), effectively detecting obstacles in the near distance and preventing collision of unmanned forklift trucks.
When the unmanned forklift truck installed with the above blind liDAR detects obstacles, the system will automatically control the vehicle body to stop moving, or trigger the three-color light and the vehicle body horn to warn, so as to ensure the safe operation of the unmanned forklift truck.
Safety is no small matter, the safety of unmanned forklift is not only a matter of protecting equipment and goods, but also to ensure the health and life safety of each participant in the working environment. Improving the safety of unmanned forklift operation and avoiding the safety risks of unmanned forklift operation are the premise and basis for efficient production and transportation of enterprises. Leishen Intelligent will continue to play its own technical advantages and integrate years of practical experience to work together with customers to create a safer and more efficient intelligent warehousing service.
