无论正流量还是负流量控制，皆是以内燃发动机（以下简称发动机）驱动的行走类工程机械液压系统之节能为目的。而节能中其关键点还是在围绕着发动机的输出功率和工程机械实际使用功率的匹配。进入2014年中国的行走机械进入欧IV标准阶段，这也标志着发动机控制系统进入了更为精确控制的阶段。CAN总线技术在发动机上的成熟应用，为液压系统的总线升级打下了良好的基础。该文正是在这种的背景下，论述了真正意义上的正流量控制，是要求液压的控制系统，对于发动机和液压负载时时精确匹配来达到能量的最小损失。而这一过程的控制正是CAN总线技术的强项所在。

Both positive and negative flow control systems are developed for the energy-saving of mobile construction machine driven by in-ternal combustion motor. The key aspect of energy-saving is to match output power of motor with service power of construction machines. China is entering into the stage of IV emission standard, which marked more precise control of motor. CAN-Bus technology’s mature appli-cation in motor lays a good foundation for hydraulic system’s bus updating. In this circumstance, this paper discussed the strength of CAN-Bus technology, which achieves minimum energy loss by constantly matching motor with hydraulic load.
