摘要
利用嵌入式高性能ARM的Cortex-M3内核微控制器芯片STM32设计多点测温系统,并给出了硬件设计的原理框图.重点阐述了温度采集端、报警电路和上下位机通信部分的设计,并进行了相关软件的设计.由于DS18B20和STM32芯片内部集成度比较高,从而简化了硬件结构.该系统具有扩展方便、可靠性高、配置简单和成本低等特点.
A method of designing multi-point thermometer is introduced in the paper, which is based on em- bedded and high performance Cortex-M3 micro-controller STM32. The hardware circuit of temperature capture terminal, alarm circuit, upper and lower machine communication part are presented, and the related software is designed. Since DS18B20 and STM32 microcontroller is highly integrated, the hardware struc- ture of the thermometer is simplified. It is convenient to extend and is outstandingly reliable, simple in configuration and low cost.
