DoricTech is committed to modernizing the traditional coal transportation chain with IoT technology. We proposed the idea of combining digital container transfer and a digital inland hub, which improves the loading and unloading process for traditional line haul transportation. The solution comprises self-developed enclosed coal containers and a series of IoT-powered smart terminals, including GPS devices, axle load sensors, and RFID sensors. They seamlessly integrate into the entire transportation process, connecting key nodes such as mines, weighhouses, and consolidation points. This interconnected network enables the visualization and real-time control of the entire coal transportation chain. Additionally, by employing 1000+ new energy trucks, we realize zero emissions at the last mile of shipping and receiving. While increasing efficiency by more than 4 times, the solution effectively reduces carbon emissions and other pollutants.
