摘　　要：起重机吊重防摇控制主要采用吊重、小车、大车等运动状态信息反馈控制小车和大车电机及吊重起升电机的驱动,进而控制小车和大车的运动状态来达到防止和衰减吊重防摇的目的。考虑到CAN总线的使用特点、控制系统中传感器位置分散和起重机的工作特点,利用CAN总线构建防摇控制系统。用单片机PIC16F877设计了CAN总线智能节点,很好地解决了控制系统中硬件可能受到的干扰抑制问题,单片机控制CAN控制器由CAN驱动器经CAN总线发送和接收现场实时数据。CAN总线智能节点的设计是基于DSP的防摇控制系统设计的前期内容之一。The trolley＇s motor, the crane＇s motor and the load＇s hoisting motor are controlled mainly using the load＇s, the trolley＇s and the crane＇s dynamic state information with feedback control for the load＇s anti-swing control system of the overhead crane or the gantry crane. Then, the trolley＇s and crane＇s dynamic state are controlled and the load＇s anti-swing is preveuted and damped. The anti-swing control system was constructed with CAN bus because the CAN bus＇ use advantage, the sensors＇ dispersive distributing in control system and the crane＇s work characteristics were taken into account. The CAN bus＇ intelligent node was designed with MCU PIC16F877. So, the problem of possible interference suppression in hardware control system was better settled. The CAN controller is controlled by the MCU and the CAN driver sends and receives on-the-spot real-time data by the CAN bus. The design of CAN bus＇ intelligent is one of the design of anti-swing control system based on the DSP.
