摘要
介绍了一种以MSP430单片机为核心的多路温度采集系统。解决了以往系统功耗大,结构复杂,灵活性差的弊端。系统采用低功耗高集成度器件MSP430F149作为主控MCU,PT100铂电阻作温度传感器,利用程控放大器MCP6S28和自带12位A/D作信号采集,使得系统功耗低、结构简洁,性能稳定,并通过RS232串口可与上位机进行通讯。此外该系统通过更换不同的传感器部分软件即可组成其他数据采集系统,灵活性好。
A multi-channel temperature acquisition system based on MSP430 is introduced in this paper.The general problems,such as power,complex structure,are solved.The system is composed of low power and high integration device MSP430F149 as main control MCU,PT100 platinum resistance as temperature sensor,programmable amplifier MCP6S28 and 12bit A/D.The system has the advantage of low power,simple structure and stable performance.Through the RS232 serial port,it is able to communicate with PC.In addition,the temperature acquisition system can be changed to other date acquisition system through exchanging sensors and partly program.
