摘要
基于ST公司的ARM Cortex-M3内核的STM32F207嵌入式微处理器,设计并实现了一种高性能、低功耗、小体积的电源监控系统方案。该系统采用微处理器内嵌的3路多通道ADC采集部件,无需外扩其他器件,即可实现对多路电源数据的同步采集,利用微处理器强大的运行能力实现各种参数的运算与分析,并利用基于RS485的Modbus协议通讯方式将数据传输给上位机进行集中管理。测试结果表明,此系统大幅度提高了电源监控系统的实时性及可靠性,并有集成度高、体积小、功耗低等优点。
Based on the ST＇s ARM Cortex-M3 as the kernel of STM32F207 micro-controller,this paper introduces a kind of low power consumption,high performance power supply monitoring system design scheme.The monitoring system uses STM32F207 multi- channel ADC acquisition chip built-in 3 road,without external expansion chip,the system can realize synchronous data acquisi- tion of multi-channel data,and by using modbus protocol based on RS485 to transmit data to PC for centralized monitoring.
