摘要
随着社会信息化人性化的发展趋势，科技产品已经越来越多的进入了人们的日常生活，如手机、电脑等科技产物已经基本达到普及的水平。手机是一种高科技的通讯设备，除了拨打电话之外，收发短信也是手机的一大功能。而短信的最大特点就是无需拨打电话，人与人之间就能进行信息传递、沟通，并且获取更多信息。
本系统给出了一种基于GSM TC35i模块的远程温度监控系统，主要由单片机和GSM短信模块组成，借助最可靠、最成熟的GSM移动网络，以最直观的中文短消息或电话形式，直接把报警地点的情况反映到手机屏幕上。其中还有时间芯片DS1302来显示实时时间，温度采集采用主动式DS18B20温度传感器进行检测，变无形的温度看成有形的显示，给检测提供方便。并配备高低温处理设备，实现温度过高或过低对设备等的影响，使工作环境安全。

ABSTRACT
With the trends of information society of human developments, technology products have already come into people's lives and become more and more. For example, mobile phones, computers and other technology products have become basically and popularity. The cell phone is a high-tech communications of equipments. In addition to calling, SMS is also a major function of cell phones. The most prominent feature of SMS is that you needn’t make a call, between people and people will be able to communicate and transmit information, and could get more information.
This system is about a distance temperature monitoring system which based on GSM and TC35i module. It made of MCU and GSM massage module. It depends on the GSM Mobile Internet which is used as the most reliable and mature. This system can tell you the locations and conditions when it was alarming, directly to the phone screen in the most intuitive form of short message (in Chinese) or telephone. It also contains a time chip DS1302 to display the real time. Collecting the temperature use a temperature sensor DS18B20 to detect which made invisible temperature change to the visible display. With the display on the screen it is very Convenience to be detected. The equipment have had a high and low temperature processing system, it would processing the temperature when it was too high or too low on the equipment, so that working environments are safe.

Keywords：MCU, GSM module, Sensor.
