基于CAN总线技术的挖掘机电子控制系统设计

先进的电子技术给工程机械设计带来了巨大的变化。第一次变化是广泛使用包括微控制器在内的电子设备,它们的应用包括信息显示、发动机控制和液压控制,但同时也增加了非常昂贵的电缆和复杂的布线;第二次变化将致力于如何通过数字通讯技术以减少这些复杂的布线。本文提出基于CAN总线技术的液压挖掘机电子控制系统设计,采用了两个控制器,分别命名为仪表控制器和发动机一液压控制器,结果大大简化了系统结构。

The Design of Electronic Control System of Excavator Based On CAN-bus

Advances in electronic technology have brought numerous changes in design of construction equipment. The first wave of the changes can be represented by the proliferation of electronic devices, including microcontroller. Their applications include information display,engine control and hydraulic control, but the increasing application of electronics has the side effect which is very expensive and complicated wiring.The second wave of the changes will be focused on how to reduce these complex wires by using digital communications. Based on the design of the electronic control system of excavator with CAN-bus, two communication controllers, i e., an instrument controller and an engine-hydraulic controller were defined, and the whole system was simplified greatly.
