- 摘要:
- 针对国内中高端的工程机械控制器市场主要被国外厂商垄断,导致工程机械控制器价格昂贵、后期维护能力差、供货周期长,而传统控制器又不能够满足现代化工程机械的控制中的高速通信需求的问题,设计了基于CANopen的工程机械控制器。选用Infineon的XC2287M芯片作为平台的核心部件,详细说明系统中各模块的作用,并且完成系统原理图和PCB的设计; 选择符合IEC61131-3标准的CoDeSys作为控制器的调度核心,进行CoDeSys Runtime的移植和I/O接口配置; 控制器采用CANopen协议应用于控制系统中,使得通信更加方便快捷; 对控制器进行基本功能测试和CAN通信测试。实验结果表明,基于CANopen的工程机械控制器能够实现对矿山工程机械的控制。
- Abstract:
- At present, the domestic middle and high levelmarket of construction machinery controller is monopolized by foreign manufacturers, this leads to the issues that the construction machinery controller is expensive, poor maintenance ability and long supply cycle, while the traditional construction machinery controller cannot meet the requirements of high-speed communication in the control of modern construction machinery.Therefore,a construction machinery controller based on CANopen was designed for solving the above problems. Firstly, Infineon’s XC2287M chip was selected as the core of the hardware platform, the hardware system design process of each module was described in detail and drawn schematic and PCB. Next, CoDeSys compliant with IEC61131-3 standard was selected as the software dispatch core, then the CoDeSys Runtime was transplanted and I/O interface configuration was implemented.Thirdly, the CANopen protocol adopted by the controller was applied to the control system so that CAN communication became more convenient and faster. Finally, the basic function test and CAN communication of the controller was carried out. The experimental results show that the construction machinery controller based on CANopen can achieve the control of mine construction machinery.
