The Empty Container Detection System adopts deep learning and acoustic signal analysis technology to realize intelligent and efficient detection of empty container/heavy container status. The equipment uses high-precision sensors, with self-detection, automatic obstacle avoidance, empty box detection, sound and light alarm, voice prompt, security protection and other functions. The equipment has short detection time, high detection accuracy safety and reliability, and can be intelligently connected with the bayonet system to achieve self-service customs clearance of vans and improve vehicle passing efficiency, and can be widely used in port, freight yard, port and other container vehicle inspection places.
