In the recent period, foreign engineering machinery technology is led by electronics and information technology. In the aspects of computer fault diagnosis and monitoring, precise positioning and operation, engine fuel control and ergonomics, a lot of research has been carried out. The matching software and hardware control system of engineering machinery makes the engineering machinery products advance to the direction of informationization and intelligence, improves the high-tech content of construction machinery, and promotes the technological development of the construction machinery industry.
Bulldozer operation control and guidance system
Some foreign powerful enterprises adopt advanced navigation systems based on GPS technology and digital map technology. They are equipped with a touch computer in the cab, which can display the position of the machine in the work area, the difference between the actual value of the work area and the design value and related. Information, even inexperienced drivers, can effectively fulfill requirements such as grade operations. Some new products enable precise control of the slope, and the cab visual display system guides the driver to precise operation with an accuracy of up to centimeter.
The computer fault diagnosis system onboard computer can evaluate the running state of the machine according to the detection signals of various sensors, combined with the expert knowledge base, predict the possible faults; issue fault information alarms or guide the driver to find and eliminate faults when faults occur. .
Diesel engine control management system
Some new diesel engines are equipped with a single-chip based fuel injection control and engine optimal performance regulation system to improve fuel utilization and ensure that engine exhaust emissions comply with environmental control regulations. The system can also communicate with other devices via the CAN bus, making the entire machine a complete management system.
In addition, the shift control system automatically shifts gears according to the driving speed and load state of the machine, and matches the engine speed with the operating conditions to achieve energy saving.
The universal application of ergonomics Because the control system can directly reflect the humanized design concept, foreign engineering machinery pays special attention to the coordination between the driver and the operation interface, and emphasizes the comfort of operation. The touch screen, text graphic display, wireless remote control and multi-function operating handle are widely used, and the operation panel layout is reasonable.
In the future, intelligent systems integrating hydraulics, microelectronics and information technology will become the mainstream development direction and will be widely used in the design of engineering machinery; computer-aided driving systems, information management systems and fault diagnosis systems will rely on microelectronics technology and The wide application of information technology is constantly improving; electronic monitoring and automatic alarm systems, automatic shifting and shifting devices will be widely used; engineering machinery for precise material excavation, loading, loading and transportation will install GPS positioning and loading. Automatic weighing device.
Based on the research of construction technology, using a combination of computer technology, microelectronics technology, information technology, wireless communication technology and automatic control technology as a means, various construction machine groups (such as asphalt mixing stations and asphalt carriers for highway construction) Intelligent research on asphalt transfer vehicles and asphalt pavers to form a construction machine group will be carried out one after another.
