摘　　要：现有伺服监控系统一般采用计算机作为上位机实现,传统方式采用RS232的上位机监控方式,但是RS232的通信距离近,波特率低而且抗干扰能力差。采用带有双CAN的STM32F407作为主控芯片及其外围电路的监控系统,采用CAN通信进行驱动器参数的配置以及监控,扩大了监控的距离,双CAN设计提高了可靠性,并针对伺服驱动器的特点设计了CAN自定义的通信帧。同时为了方便在没有上位机时的监控,设计了按键数码管监控驱动器的方式,进一步提高了系统的工作范围和可靠性。采用AT24C02作为存储芯片,对系统的参数进行存储,设计了两个存储区域,提高了系统的可靠性。该设计具有较高的可靠性的驱动器监控系统,具有重要参考价值。The existing servo monitoring system is usually realized by PC,and the traditional way is RS232,but the communication distance of RS232 is short,baud rate is low and anti-jamming ability is poor.In this design,STM32F407 with dual CAN is used as the main control chip and its peripheral circuit monitoring system,CAN communication is used to configure the driver parameters and monitor,and the monitoring distance is extended.The dual CAN design improves the reliability,and according to the characteristic of servo driver,a CAN-defined communication frame is designed in this paper.At the same time,in order to facilitate the monitoring in the absence of a PC,the design of digital control button driver to monitor the way to further improve the working range and reliability of the system.AT24C02 is used as the memory chip to store the system parameters,and two memory areas are designed to improve the reliability of the system.This design has the high reliability drive monitor system,has the important reference value.
