Under the crazy sweep of the new energy wave, the downstream value chain of construction machinery is rapidly achieving a "pure electrification" transition. However, as the most classic mining operation scenario for construction machinery, the working environment is harsh and the operating conditions are simple, resulting in inherent insulation of pure electric equipment. However, hybrid devices have become the best solution to replace traditional fuel equipment due to their advantages of no range anxiety, no charging restrictions, and greater fuel efficiency. At the same time, mining operations are constantly facing scenarios that may affect safety operations, such as landslides, sudden winds, and dust. However, the combination of hybrid technology and 5G remote driving can completely overcome two major challenges, achieving a revolution in efficiency and safety upgrades in mining operations.
Hybrid technology: empowering mines to open a new chapter
Although "green mines" and "smart mines" have become the main directions for mining development and construction, the objective problem of "difficulty in using electricity" in mining operations has become a bottleneck for switching electric equipment, and the emergence of hybrid technology provides a perfect solution. The hybrid loader of Yingxuan Heavy Industry achieves efficient conversion between "oil" and "electricity" through the national four high-power integrated range extender, completely solving the common range problem of pure electric loaders.
Hybrid loaders exhibit strong adaptability to complex mining environments. Taking the YX670HEV heavy-duty hybrid loader as an example, the entire machine is equipped with a large capacity lithium iron phosphate battery that supports pure electric operation mode. With the intelligent temperature control system of the battery, it can maintain stable operation in high temperature or cold areas. Combined with a 330 liter large capacity diesel tank, it can achieve nearly 30 hours of continuous operation, which is more in line with the practical operation of "resting people but not vehicles" in mining conditions. Compared with traditional fuel loaders, hybrid loaders can achieve a comprehensive fuel saving rate of ≥ 35%, with an annual fuel cost savings of over 200000 yuan per device. With the advantage of no urea consumption, the comprehensive operating cost has been reduced by 42%, truly meeting the core demands of customers for peace of mind, convenience, and cost savings.
5G remote driving: reshaping the safety boundaries of mines
With the intelligent empowerment of 5G remote driving technology, drivers can completely bid farewell to high-risk work sites. The driver only needs to sit in the control center and can accurately control the loader from hundreds of kilometers away through the 5G cockpit. This remote operation mode not only liberates drivers from harsh environments such as high cold, scorching heat, sudden winds, and dust, but also builds a comprehensive safety barrier through triple technological advantages.
·Immersive driving experience
The 5G remote driving technology is equipped with multiple sets of binocular cameras to achieve a 720 ° panoramic high-definition view, and can synchronously transmit the vehicle's images and sounds at the work site, allowing the driver to clearly perceive the surrounding environment. The 5G cockpit uses a reverse torque steering wheel to control the vehicle's steering, providing a remote driving experience that is no different from a real car.
·The sense of security empowered by technology
The whole machine is equipped with intelligent reverse obstacle avoidance function, which can automatically sense the distance of obstacles and display the distance in the 5G cockpit. When entering emergency distance, the whole machine can brake independently, achieving dual protection of active prevention and intelligent response. In order to ensure driving safety and operational efficiency, the 5G cockpit display screen displays real-time information on the vehicle's track deviation and corrects the vehicle's travel trajectory in real time. Both the whole machine end and the 5G cockpit end are equipped with emergency switches, which facilitate emergency braking in special situations.
·Instantaneous feeling empowered by 5G
Faced with the objective situation of remote terrain and poor signal in mining operations, the whole machine is equipped with a warning system before operation to automatically judge the quality of the network environment. 5G remote technology adopts a network dual channel mode to achieve coexistence of local area network and 5G network, and the selection is confirmed based on environmental conditions. Through dedicated network channels and program design, when one network control fails, another control method intelligently intervenes to maintain smooth signal transmission. With 5G high-speed communication technology, the whole machine can achieve millisecond level response, breaking the time and space boundaries of remote control. Relying on the instantaneous sense of 5G communication, the efficiency of the whole machine's shovel loading is close to the operational efficiency of integrating humans and vehicles.
The integration of hybrid technology and 5G remote driving technology is redefining mining operation standards, not only helping mining enterprises achieve cost reduction and efficiency improvement, but also promoting the entire industry to move towards intelligent transformation towards safety, efficiency, and environmental protection. With the continuous advancement of intelligent technology and the upgrading of product technology routes, the future of mines will achieve a new vision of "unmanned mining, remote operation, and intelligent management".
