The Port of Nanjing is an inland port on the Yangtze River in Nanjing, Jiangsu Province, China. The port, previously using a passive infrared sensor system with an alarm rate up to 90%, needed an effective detection and warning system to help prevent warehouse damage and other potential accidents during heavy equipment operations. It also required a system that would trigger video surveillance cameras and record events.
The port’s management sought out Quanergy Systems, a provider of LiDAR sensors and smart 3D solutions, and ultimately deployed Quanergy’s M-Series LiDAR sensors to provide highly accurate measurement and detection. Features of the M-Series include low false alarms, long object classification range up to 70 meters, 360-degree horizontal view and native integration with VMS and PTZ cameras that include support for Genetec and Milestone video management systems.
“This deployment further extends Quanergy’s presence in the port automation market, one of the first industrial segments to embrace the power of 3D LiDAR,” said Tony Rigoni, director of industrial markets, Quanergy Systems Inc.
The reasons Nanjing Jiuao selected Quanergy’s LiDAR-based system was because of some key benefits of Quanergy’s sensor solutions. The solutions would provide accurate and reliable detection even in harsh warehouse environments – LiDAR sensors aren’t impacted by environmental factors, as other sensors are. Quanergy’s solutions also includes 3D object identification that reduces false alarms because it can differentiate between small animals, like birds and machinery or people. It also provides coverage of a much larger area per sensor than other traditional sensors, requiring fewer devices and reducing acquisition, installation, and management costs.
The impact was quickly evident, as Quanergy’s LiDAR-based system brought the false alarm rate down to about 2% and met Nanjing Port’s requirements for timely detection and warning capabilities.
“With the data provided from Quanergy’s LiDAR system, our customer’s warehouse team has been able to have a more accurate visual display of the operations area,” said Sheng Teng, general manager, Nanjing Jiuao.
