摘　　要：针对用插装阀组成的拖拉机电液悬挂系统,给出了基于CAN总线的悬挂控制方案,主要包括悬挂子系统ECU、2个智能节点。智能节点的设计以LPC2119芯片为核心,具有硬件简单、封装小巧、软件模块化强的特点。试验表明,该节点能很好地满足悬挂系统的工作要求。at tractor electronic hydraulic hitch system constituted of cartridge valve, the electronic hydraulic hitch controller based on CAN bus, which included hitch subsystem ECU and two intelligent nodes was introduced. The developed intelligent node with hardware core of LPC2119 chip had characteristics of hardware in brief, smart pack, and software in blocking. Experiments verified that the developed nodes could satisfy the work request of hitch system.
