Tongli Heavy Industry: The number one in the unmanned off-road wide-body dump truck industry!

Preface: In 2017, based on the by-wire system and by-wire chassis of Tongli Heavy Industry, Tongli Heavy Industry and Tage Intelligent Travel jointly developed the industry's first unmanned off-road wide-body dump truck, marking the official launch of unmanned technology research and development and manufacturing in the off-road wide-body dump truck industry.

Looking back on the application and development process of unmanned driving technology in the domestic non-road wide-body dump truck industry, we have gone through the process from nothing to something, from testing to road use, and from single-vehicle and single-group operation to multi-vehicle and multi-group operation. The process has been solid and arduous, and each stage has left the footprints of the "pioneers" constantly surpassing themselves.

Customer pain points trigger technological breakthroughs

For a long time, mining customers have been facing multiple "pain points" in the management of mine transportation. Firstly, the mining area has a complex environment, with significant variations in working conditions. It is difficult to recruit and manage workers, and the proportion of labor costs in the total income is high. Secondly, due to limitations in human resources, vehicle dispatching and other links, the improvement of mine transportation efficiency has encountered bottlenecks. Thirdly, wide-body vehicles have long operating hours and high working intensity, which makes them prone to production safety accidents.

Based on the analysis of the current situation of construction management mentioned above, the demand for fewer or no personnel in mines has become increasingly clear and urgent. The application of driverless technology can avoid the uncertain factors of "people". Once this breakthrough is made, it can further improve the efficiency of production operations. Meanwhile, through information and digital technologies, driverless technology can reduce costs such as vehicle maintenance, high fuel consumption, and tire damage caused by non-standard operations, help avoid driver casualties, and truly achieve intrinsic safety and cost reduction and efficiency improvement in production operations.

Since 2016, the state has been continuously promoting the intelligentization process of mines. At that time, the application of autonomous driving technology on public roads attracted much attention, while unmanned driving technology in domestic mines was still in its infancy, with unclear technical routes and application scenarios. As the pioneer and leader of non-road wide-body dump trucks, based on its understanding of the elements in the short-distance transportation of bulk materials in open-pit mines, as well as Tongli Heavy Industry's dedication and responsibility to meet customer needs, relying on years of accumulation in the wide-body dump truck industry, Tongli Heavy Industry has proactively laid out research on product intelligence and embarked on the path of improving unmanned driving technology for wide-body vehicles.

Application of unmanned off-road wide-body dump trucks in mines

Driverless wide-body vehicles emerged in response to The Times

From August to December 2017, Tongli Heavy Industry independently modified a TLD65 wide-body vehicle and named it TLI65. This was the first wire-controlled wide-body vehicle in the industry. In December of the same year, Tongli Heavy Industry's wire-controlled wide-body dump truck completed road tracking driving. This was the first test vehicle in the industry capable of autonomous driving.

During the same period, Tage Zhixing, the first domestic technology enterprise dedicated to unmanned transportation solutions for mines, coincided with Tongli Heavy Industry's principle of "taking the demands of mine construction as the core, continuously leading with technological innovation, and developing high-efficiency and high-reliability products" and its spirit of striving for excellence in industry. The two sides joined forces strongly Innovative cooperation in the research and development and manufacturing of unmanned driving technology in the industry has been initiated.

In January 2018, based on the by-wire system and by-wire chassis of Tongli Heavy Industry, the industry's first unmanned wide-body dump truck, jointly developed by Tongli Heavy Industry and Tage Intelligent Travel, rolled off the production line at Tongli Heavy Industry. This marked the official start and growth of unmanned off-road wide-body dump trucks, and the research and development and manufacturing of unmanned driving technology in the industry officially began. This vehicle integrates the advanced by-wire control system and control algorithms of that time, adapting to the characteristics of application scenarios such as unstructured roads in mining areas, large size of wide-body vehicles, and significant variations in load capacity. From testing to road use, it marked the beginning of autonomous driving of off-road wide-body dump trucks in the industry.

China's first driverless wide-body vehicle

By 2022, Tongli Heavy Industry's unmanned driving by-wire system had been continuously upgraded from version 1.0 to 2.0, 2.5, and 3.0, achieving new technological breakthroughs in the linkage between the unmanned transportation system and the coal crushing system, as well as in replacing traditional manned vehicles to realize regular, large-scale, and unmanned production operations. In the mining area, a stable capacity replacement for raw coal transportation has been formed, achieving fully unmanned group operation in multiple closed scenarios throughout the entire process.

The future path of gathering strength and energy

During the development of unmanned off-road wide-body dump trucks, Tongli Heavy Industry has joined forces with unmanned driving technology providers such as Tago Intelligent Travel to jointly develop, aiming to create professional products to the ultimate level and seize the window of opportunity for the technological transformation and demand meeting of unmanned driving in mines.

Based on the line control system of Tongli Heavy Industry, the unmanned driving products have achieved a transformation from single vehicles and single groups to multiple vehicles and multiple groups through five years of technological improvement and application verification. From unmanned operation during the driving process to unmanned operation throughout the entire "loading - transportation - unloading" process; From simple dispatching of roadside units to in-depth collaboration of "vehicle-road-cloud"; From the basic realization of functions to the orderly, smooth, secure and controllable system; From single-shift testing to continuous shift operation, we have achieved phased ideal results.

The unmanned driving system features deep collaboration among vehicles, roads and clouds

Today, the waves of intelligence and the Internet of Everything are breathing new life into the construction machinery industry. Tongli Heavy Industry will continue to maintain an open attitude, join hands with business partners such as Tago Intelligent Travel, and jointly focus on the unmanned driving field in mines. Relying on technology, it will embrace new energy and master unmanned driving, striving and pursuing its dreams unremittingly to jointly build environmentally friendly, safe, smart and minimally manned mines.
