介绍了一种基于CAN总线进行通信的轴角数据转换电路.在设计上,以dsPIC30F系列的DSP为核心处理器,通过轴角转换模块来实现数据的转换.以MCP2551作为高速CAN转换器,结合DSP片内集成的CAN总线控制器,来实现数据和外部的通信.该电路在设计上以DSP为核心,通过采用隔离芯片来保证电气隔离,从而降低外部环境及电路对通信的干扰,最终通过编程实现CAN总线通信功能;设计主要完成了轴角数据的转换、工作状态监督检测反馈和基于CAN总线的通信等功能,具有高速度、高精度、高可靠性的特点,可广泛应用于轴角转换和控制系统等领域.

This paper proposes design and realization for the synchro/resolver data conversion circuit based on CAN bus communication. The hardware and software function of the circuit are designed based on DSP. The circuit uses a high speed CAN bus converter and a CAN bus controller to achieve the internal and external communication. The design uses the dsPlC30F family of DSP as the core components, and uses an isolation chip to ensure electrical isolation, thereby reducing interference with external circuitry for communication. After the hardware circuit design completion, through software programming,the entire design ultimately achieve the overall （unctionality. The design has advant...
