Hitachi Construction Machinery introduced their Aerial Angle peripheral vision display system with object detection technology at MINExpo this week.
Hitachi's Aerial Angle technology enhances the visibility for mining equipment operators by alerting them to obstacles when driving, stopping or starting their dump trucks.
The new object detect assist technology features two operating modes – Stationary Mode, which incorporates camera image processing technology and Forward Mode, which incorporates millimeter wave radar technology developed by Hitachi, Ltd.
In Stationary Mode a warning is provided to the dump truck operator when the vehicle is stopped or starting to move if any moving objects such as other vehicles are detected nearby. The warning is displayed in the driver's seat monitor with accompanying sound. Moving objects are recognized through images captured by cameras mounted on the front, rear, left and right sides of the dump truck. By quickly notifying the operator of any changes to the surrounding environment, the system contributes to improved operator awareness.
In Forward Mode a warning is sent to the operator while driving when approaching another vehicle on the road ahead. The approach warning is displayed in the driver’s seat monitor with accompanying sound. This mode uses millimeter wave radar, which is effective in poor visibility conditions such as rain, snow, fog or dust.
Two types of warnings are provided to the operator based on the radar data, according to factors such as the approach distance and relative speed of the object.
The Aerial Angle object detect assist technology is also being integrated into Hitachi’s driverless autonomous dump trucks that are currently in development.
“Customers around the world are striving to enhance efficiency of the entire mining supply chain,” said Craig Lamarque, division manager, Hitachi Construction Machinery. “As a result, there is an increasing demand for machinery manufacturers to incorporate information communications technology (ICT) into mining machinery and management systems, and to provide solutions that integrate these technologies. This technology addresses the important customer issues of enhancing operator awareness, improving productivity and reducing life cycle costs.”
“Hitachi Construction Machinery Group embraces the ‘One Hitachi’ concept of using the construction machinery technology that it has accumulated over many years in combination with its strengths in ICT, control and Internet of Things technology.”
