【摘要】 设计了基于CAN总线的铁路救援起重机的调平控制系统,阐述了支腿自动调平的方法,分析了支腿自动调平的过程。系统主要采用派芬的EPEC控制器和带CAN口的双轴倾角传感器,司机的操作指令和起重机的支腿控制机构状态的改变由EPEC控制器实时扫描,再进行逻辑和数据运算,通过CAN总线作为信息交换通道。设计了自动调平的程序流程并作分析,根据流程运用CODESYS软件平台对控制器进行了编程。更多还原

【Abstract】 The paper introduces a CAN bus based leveling control system for railway rescue crane,describes the automatic leveling method for outriggers,and analyzes its automatic leveling process.The Pal-Fin EPEC controller and dual axis tilting angle sensor with CAN port is adopted for this system.Operating instructions for drivers and changes in the status of the outrigger control mechanism are real-time scanned by the EPEC controller,with further logic and data calculation,and CAN bus is used for information exchange.The process flow of automatic leveling is designed and analyzed,with programming for the controller by CODESYS software.更多还原
