摘　　要：为解决电机控制系统运行参数的多通道实时监测可能影响系统正常调试和运行的问题,提出了异步电机PWM控制系统主控制器TMS320F28069与副控制器TMS320F2812配合使用的新方案,设计了一种通过主、副控制器的e CAN模块实现的基于CAN总线的电机测试数据通信系统的硬件和软件,并采用TI公司自带图形显示功能的CCS3.3集成开发工具,实时监测显示多通道变量波形。实验结果表明,该测试数据通信系统具有抗干扰能力强、实时性好、准确性高、简单可靠,且对主控制程序执行无影响等特点。Aiming at the problem of the normal testing and running of motor control system was affected by monitoring the multi-channel internal operation datum of system, a new scheme was put forward, where main controller of PWM induction motor control system TMS320F28069 and auxiliary controller TMS320F2812 were cooperated. The hardware and software of communication system of tested datum on CAN bus were designed by e CAN modules of main and auxiliary controllers. The waveforms of multi-channel variables were monitored and shown in real time with graph function of TI integrated design tools CCS3. 3. The experimental results indicate that the communication system of tested datum peculiarity such as strong anti-interference ability,good real-time,high accuracy,simpleness,reliability,no effect to main control program,and so on.
