摘要
采用TI公司的54系列MCU最新型号MSP430F5438为终端控制核心,通过SHT10和MQ-2传感器采集环境中的温度、湿度、烟雾可燃气体参数,并用GPS定位监测点,以SIM300无线传输将数据及定位坐标发回控制中心的上位机以分析。上位机软件采用C++Builder配合SQL Server 2000编写,对采集的数据进行实时处理分析,并用跟踪曲线斜率的算法做出预警。由于利用该MCU特有的多种低功耗模式及外设与CPU独立工作的特性,终端的电力持续时间大大增加。
Using TI＇ s latest model MSP430F5438 of 54 series MCU as core processor, sensors of SHTIO and MQ-2 are used to collect the parameters of temperature, humidity and smoke, monitoring points are located by GPS, the sensor data and the location coordinate are sent to control center by GPRS/GSM module SIM300. The software in control center is made by C ＋＋ Builder with database SQL Server 2000, in which the data is further processed and analyzed in real-time, and early warnings can be given efficiently by the method of tracking the slope of the curve. As the use of the unique low-power modes and a variety of peripherals working independently of the MCU, the duration of the terminal＇ s power is greatly increased.
