设计题目:基于GPRS的远程无线温度采集系统的设计
摘要
GPRS作为一种高速、高效、经济的无线系统,具有网络覆盖范围广、数据带宽宽、适应性强、计价按数据流量计算、实时在线的优点,特别适用于间断的、突发性的或频繁的、少量的数据传输,能够满足数据采集及监控的双向数据信息传输。
文中设计了一种温度控制系统,提高了温度检测系统的综合性能用单片机作为微控器,选用数字温度传感器,对温度进行控制,提出了一种基于GPRS技术的远程温度监测系统方案,采用MSP430单片机和DS18B20数字温度传感器实现现场温度数据的采集和处理,再通过GPRS模块MG323实现远程的数据传输和接收,具有精度高、稳定性好的特点。硬件方面设计了一个基于单片机的温度智能控制系统,以MSP430单片机为核心,采用了温度传感器DS18B20,以GPRS无线通信模块为基础,基于AT指令和数据采集器,构建一个远程的温度数据采集系统,对温度进行控制。

Abstract
GPRS as wireless a high-speed, high efficiency, economy system, has a work coverage, according to the data with Eric, strong adaptability, valuation data flow calculation, the advantages of real-time online, especially suitable for intermittent, sudden and frequent, small amounts of data transmission, can satisfy the data acquisition and monitoring of the bidirectional data transmission.
In this paper, we design a temperature control system, improve prehensive use of temperature detection system single chip as micro controller, digital temperature sensor, the temperature control, puts forward a remote temperature monitoring system scheme based on GPRS technology, the scene is realized by using MSP430 MCU and DS18B20 digital temperature sensor temperature data acquisition and processing, again by MG323 GPRS module to achieve remote data transmission and receiving, has features of high precision and good stability. A hardware design based on single chip puter intelligent temperature control system, with MSP430 single chip puter as the core, adopting the temperature sensor DS18B20, based on the GPRS munication module, based on the mands and data collector, to build a remote temperature data acquisition system, to control the temperature.
