简要综述了工程机械中控制与操纵系统的发展历程和关键技术；提出了基于现场总线控制的网络控制实现功率传输和运动控制与综合的新方案；以应用于上海磁悬浮铁路工程轨道梁搬运的工程机械的计算机控制系统为例，讨论了基于现场总线控制系统(FCS)和PC104车载工控机的车辆计算机网络控制系统的设计方法和控制策略；研究结果为大型车辆与工程机械的控制与操纵提供了新的实现途径。

This paper surveys the development history and the relative key technology of the control and manipulating system in the huge transporter and construction machinery, and proposes a new kind of scheme to realize the transmission of power, motion control and synthesis based on network control by field-bus control. Taking the computer control system of the engineering machinery applied in the transporting of the railroad bridge in the Shanghai suspension magnetic railway as example, the design method and control strategy of the network control system based on the configuration of the field bus control system and PC104 airborne industrial control computer are discussed. The research conclusions provide the new approach to realize the control and manipulation of the huge transporter and construction machinery.
