摘要
介绍了一种基于CAN总线的设备监控系统的设计方法,监控的对象是不同品牌的PLC。系统由一个主站模块和30个分支节点模块组成,各模块均采用ARM Cortex-M3内核的STM32F107系列单片机,它拥有内置CAN控制器,能够高效的实现CAN总线通信。此外,各节点模块还拥有多种通信接口,支持多种PLC通信协议。
This paper presents a method to design a kind of equipment monitor and control system based on CAN bus. The system is consist of PLCs in different brands, one Master module and 30 Slaves, each of which has a STM32F107 MCU with Cortex-M3 core, containing an internal CAN bus controller that makes the CAN bus works efficiently. In addition,each module has multiple transmission interfaces and supports communication protocols of all the PLCs on line.
