Australian Coal Mine Uses V2V Communications
Thursday, May 14, 2020 | Comments

Rajant and Hitachi Construction Machinery Australia are improving operational safety and productivity through the use of autonomous haulage systems in an Australian coal mine. Hitachi selected Rajant Kinetic Mesh as its industrial wireless network enabling vehicle-to-vehicle (V2V) communications, which allows autonomous vehicles to talk directly to each other, providing enhanced coverage and reliability.

“Rajant is a Hitachi central wireless network partner for the mining industry when it comes to automation,” said Hitachi’s Greg Smith, general manager AHS business unit, Australia. “Deployed in 200 of the largest mines globally, Rajant has the network Hitachi relies on for our autonomous haulage systems, significantly reducing human exposure to safety hazards in mining’s hostile environments.

In the Australian coal mine deployment with Hitachi, there are six autonomous haul trucks in production, scaling to more than 45 during 2020 and 2021. The mine’s existing Rajant wireless network deployed across a vast number of mobile and fixed infrastructure easily met the requirements to support and enable Hitachi’s autonomous operations. Additionally, Hitachi systems can be retrofitted onto existing vehicles expanding their scope and market significantly.

“Hitachi has experienced and witnessed that Rajant networks dynamically adapt to evolving conditions and make multiple connections over multiple frequencies per node for continuous, mobile connectivity,” said Smith. “This level of mission-critical reliability is a mandate for V2V and particularly for autonomy.”
