As we all know, the traditional roller has multiple controllers, and the engine, hydraulic system and complete machine are controlled by different controllers. Because they are "divide and rule", the degree of cooperation between them is poor. During the construction, the engine works in a high-speed and high-fuel consumption area, and the oil consumption and noise are relatively high. In addition, the mechanical operation mode of the traditional road roller leads to high labor intensity and poor operation experience of the driver.
Leading the development of the industry! Video Introduction of Weichai Road Roller Intelligent Control System.
So, is there any way to solve this situation? The answer is yes.
On October 21st, at the autumn new product launch conference of Weichai-Shantui held in Jining, Shandong Province, Weichai launched the "Intelligent Control System of Roller".
Intelligent control system, core assembly!
According to the reporter from machinery network of the First Project, the control system of Weichai road roller is composed of Weichai engine+Linde hydraulic system +ECU integrated control system. Weichai has created the super brain of integrated intelligent control of hydraulic power train of road roller, and brought more core competitive power train solutions to road roller enterprises and customers.
The WP4.6N series engine displayed in this activity is the whole new generation platform intelligent control roller power built by Weichai according to the latest research and development design concept. Under intelligent control, the engine can be intelligently and adaptively adjusted according to the characteristics of working conditions, and always works in the best fuel consumption area, with lower fuel consumption and lower noise, and the operation performance is improved by more than 10%.
The intelligent control system of road roller adopts a new generation Linde hydraulic system, which is characterized by intelligence, precision, high efficiency and reliability! Linde Electric Proportional Variable Pump is adopted as the walking pump and vibration pump of the new generation Linde hydraulic system, which changes the control configuration of traditional road roller, makes the speed control more stable, the vibration frequency more accurate, saves time and effort, and makes the road construction of road roller more intelligent and simple. At the same time, it has high volumetric efficiency, which is greatly improved compared with competing products in the industry, and is efficient and energy-saving.
The electronic control unit used in Weichai road roller intelligent control system is the world's first integrated intelligent control ECU for road rollers. It can control both the engine and the whole vehicle, realizing intelligent integrated control, creating a precedent in the industry and making the engine operation more intelligent and efficient. This intelligent ECU not only reduces the transmission between control systems and improves the transmission efficiency, but also eliminates the wiring harness for signal transmission and reduces the equipment failure points.
Three advantages, meet customer needs and create more value.
It is understood that Weichai's intelligent control system of road roller is a bold innovation to better meet the needs of customers. It directly hits the pain points of the industry and customers, and its unique three significant advantages can well meet the value needs of customers, which is of epoch-making significance.
First of all, intelligent oil consumption control of intelligent control system of road roller makes the whole machine more fuel efficient.
According to the actual measurement by the manufacturer, the engine speed will be adjusted adaptively according to the working conditions during construction (matched to the low-speed economic zone). Under the same speed and vibration frequency, the oil consumption of road rollers with intelligent control system can be reduced by more than 20% compared with the mainstream products in the industry.
Secondly, intelligent NVH control makes the whole machine quieter.
After optimizing the intelligent control system of road roller, the noise of each working condition is reduced by more than 2 dB, and the noise of cab is reduced by more than 3 dB, which can make the operator have a more comfortable driving experience.
Thirdly, intelligent thermal management technology+low speed matching can solve the emission problem.
Traditional roller works in high-speed and low-load area, and the efficiency of temperature discharge is low. With the continuous upgrading of emission regulations, it is difficult to meet the emission requirements. The intelligent control system of Weichai road roller can match the engine operation to the low-speed and high-load area, and make the temperature discharge more efficient. It can achieve the balance of carbon deposition and carbon elimination under normal working conditions, effectively avoid urea crystallization, and easily meet the emission upgrade requirements of the national fourth grade of off-road mobile machinery.
The intelligent control system of road roller developed by Weichai has realized the intelligent control of the whole vehicle, which can be described as "the core of intelligent control and super aggregation". It not only provides high-end intelligent control for equipment, and realizes low oil consumption and low noise, but also makes sufficient preparations for future construction machinery to realize four-stage emission. We have reason to believe that Weichai has opened a brand-new "intelligent control era" for the road roller industry!
