摘　　要：缆载吊机是建造大跨度悬索桥的关键装备,具有功能复杂、作业环境恶劣、性能要求高等特点,这对其控制系统的设计提出了更高要求。根据缆载吊机的机械结构和液压系统,提出了基于CAN总线的缆载吊机控制系统总体设计方案,对总线上主要节点的硬件和软件进行了详细设计,使用主从式PID算法实现了缆载吊机提升节段梁的同步控制,并通过吊装试验对控制算法进行检验,验证了控制系统的提升性能。With the characteristics of complex function, poor working environment, high performance requirements and so on, deck erection gantry is the key equipment for building long-span suspension bridge, which puts forward a higher demand on the design of its control system. Based on the mechanical structure and hydraulic system of the deck erection gantry, this paper puts forward the overall design scheme of the CAN- bus-based control system and detailed design of the hardware and software for the major nodes on the bus. By using the master-slave PID control algorithm, the system can realize the synchronous control of lifting deck units. The control algorithm is tested by a lifting experiment, and the performance of the control system is verified.
