基于GSM的温度数据采集

I 摘要

随着GSM(Global System for Mobile communication)移动通信网络的迅速普及和竞争的日益激烈，新技术和新业务的开发和应用已经提到一个十分重要的位置。短消息业务（SMS）作为GSM网络的一种基本业务，已得到越来越多的系统运营商和系统开发商的重视，基于这种业务的各种应用也蓬勃发展起来。

温度是工业生产过程中测控的重要参数之一，在国防、军事、科学试验及工农业生产过程中，温度的测量和控制具有十分重要的作用。尤其在航天、材料、能源、冶金、化工等领域中，温度测量占有极重要的地位。利用GSM短消息业务能够实现数据的远程通信，这一技术适用于野外测量环境，在工业监测领域中有着广泛的应用前景。

本文针对生产生活中温度测量的需要，以GSM网络作为远程信号的传输平台，在可行性和实用性的原则指导下，以STC89C52单片机为控制核心，利用DALLAS（达拉斯）公司生产的DS18B20温度传感器、数据通信模块（GSM模块MZ28，通过标准AT指令控制）和直流电机驱动模块等外围电路元件实现温度的采集和数据的传输的功能。

II Based on GSM temperature date collection

Abstract

Along with rapid popularization and furious competition of GSM network, research and

application of new technology and new operation have been mentioned to a quite important

position. SMS as a basic service of GSM network has been attended by more and more system

operator and developer, and kinds of applications based on this service have been rapid developed.

The temperature is industrial production process, one of the important parameters for

measurement in defense, military and scientific experiments and industrial and agricultural

production process, temperature measurement and control has a very important role. Especially in

aerospace, materials, energy, metallurgy, chemical industry, etc, temperature measurement

occupies an important position. Using GSM short message service can realize the data remote

communication; this technology is suitable for field measurement environment, and in the field of

industrial monitoring widely.

Aiming AT the production and living with the needs of measurement temperature, GSM

network as remote signal transmission platform, the feasibility and practicability, guided by

principles of STC89C52 microcontroller as control core, DALLAS (DALLAS) using the

temperature sensor DS18B20 production company, data communication module (GSM module

MZ28, through standard AT command control) and dc motor driver module peripheral circuit

components to realize the collection of temperature and data transmission function.

Keywords: GSM；Temperature measurement；Remote detection；STC89C52；DS18B20；MZ28；AT instructions
