基于无线通信网络技术的远程监控系统设计
摘要
近年来,远程监控技术越来越多的受到人们的关注。远程控制技术是对受控对象进行远距离控制和监测的技术,它是利用自动控制技术、通信技术和计算机技术实现的远程监控系统。本文介绍了一种基于无线通信网络技术的远程监控系统,系统以GSM网络为基础,以AT89S51单片机为控制器,可实现对室内温度的监控和安全的监控功能,利用DS18B20采集室内温度数据,
通过液晶显示器显示出来,同时可实现超限报警,并每隔一段时间向手机用户发送一次温度数据;利用红外对射方式实现防盗功能,当产生防盗信号或者温度超出设定范围时,都会实现现场报警,并向手机用户发送报警信息。

Design of remote monitoring system based on wireless
work technology
Abstract
In recent years, remote monitoring technology is getting more and more attention by people. Remote control technology can remote control and monitor the controlled object. It use the automatic control technology, communication technology puter technology to achieve the function of remote monitoring. This paper introduced a remote monitoring system which is based on the work technology. The system is based on the work, and take the AT89S51 single-chip processor as the controllor. The system can achieve the monitoring function of the temperature of the house and the safety. It use the DS18B20 to acquisite the temperature data, through the LCD display, and can be realized at the same time overrun alarm. The system will send temperature data to the mobile phone users every once in a while. The system use the infrared shooting mode to achieve the anti-theft function. If there is security signal or the temprature is beyond the range of the setting range, the warning will alarm and the system will send warning information to the mobile phone users.
