基于短信回傳的溫度監(jiān)測(cè)節(jié)點(diǎn)設(shè)備設(shè)計(jì)

摘  要

GSM模塊，是一個(gè)類似于手機(jī)通訊模塊。集成了手機(jī)若干功能于一塊電路板上，它可以實(shí)現(xiàn)收發(fā)短消息，通話等功能。擁有它就相當(dāng)于擁有了手機(jī)的核心部分。在很多領(lǐng)域都有應(yīng)用。本項(xiàng)目是基于TC35的GSM模塊遠(yuǎn)端監(jiān)測(cè)監(jiān)控節(jié)點(diǎn)溫度。其設(shè)備有單線溫度傳感器DS18B20、試驗(yàn)用單片機(jī)、GSM模塊TC35等構(gòu)成。首先單片機(jī)要實(shí)現(xiàn)溫度監(jiān)測(cè)的功能，通過(guò)單片機(jī)上的溫度傳感器采集到周圍溫度并顯示在顯示器上。其次實(shí)現(xiàn)單片機(jī)與GSM模塊的通信，手機(jī)發(fā)送短信給GSM模塊的SIM卡，GSM模塊收到單片機(jī)上當(dāng)時(shí)溫度，將其上傳至電腦或者網(wǎng)絡(luò)，做數(shù)據(jù)分析和備份。GSM模塊是通過(guò)AT指令控制的。

本文主要是從GSM模塊TC35模塊的使用著手研究。首先要清楚該模塊的功能。再了解該模塊的使用方法。該模塊通過(guò)AT指令來(lái)收發(fā)短信，從而達(dá)到遠(yuǎn)程控制和測(cè)試的作用。其次，了解單片機(jī)的使用方法和作用。并自主編程，從而達(dá)到預(yù)期要求。最后了解整個(gè)設(shè)計(jì)流程的大體框架。做出電路圖和原理圖。

Abstract

The GSM module is similar to the mobile communication module. Integration of several functions of the phone, he can receive and send calls and other functions in a circuit board. Has it the equivalent of a core part of the mobile phone. Has applications in many fields. This project is based on remote monitoring of the TC35 GSM module to monitor the junction temperature. Their equipment has single-wire temperature sensor DS18B20 test of microcontroller, GSM module TC35. First single-chip temperature monitoring function, the acquisition by the temperature sensor on a single chip to ambient temperature and displayed on the monitor. Followed by communication between SCM and GSM modules, mobile phones to send text messages to the SIM card of the GSM module, GSM module receives the SCM temperature, and upload it to your computer or network, doing data analysis and backup. The GSM module is controlled via AT commands.
