摘要
本系统以MSP430F149单片机为核心控制器件,外部加上其它功能模块,实现了室内温度调节,声光报警及GSM短信火警预报的功能。MSP430单片机本身具有高可靠性,而且在系统设计中充分利用了MSP430单片机管脚功能转换的特点与外围检测电路相结合,通过硬软结合,排除干扰信号,所以在很大程度上加强了系统的稳定性、可靠性。低功耗是本系统设计的重要理念,本系统设计主要工作在低功耗模式LMP3中。
The system uses MSP430F149 microcontroller as the core control device, with other externalfunctional modules, which achieves the functions of the indoor temperature regulation, sound and light alarmand GSM-texting fire alarm. MSP430 microcontroller is highly reliable, because the design makes full use ofthe combination of the pins conversion functions of MSP430 microcontroller and external detection circuit,which eliminates interference signals through hardware and soteeare combination. It greatly enhances thestability and reliability of the system. Love power consumption is an important design concept of the system.Therefore, the system is designed to work most of the time in low-power mode LMP3.
