基于射频卡的GSM远程监控报警系统的设计
摘要:本系统主要由STC89C53单片机,GSM模块TC35,超声波模块,红外发射接收模块,ID卡模块,NRF2401等模块组成,借助可靠成熟的GSM移动通信网络,以最快捷的短消息或电话方式,直接把家庭最新情况传送您的手机屏幕上,也可以通过手机打电话,短信方式控制家庭中的电器设备。该系统中采用超声波传感器,烟雾传感器,震动传感器,红外检测传感器等一系列传感器由单片机检测,后进行数据编码打包,通过多个短程高速通讯模块NRF2401进行实时数据无线传输,继而组成一个现场传感器网络系统,再由GSM模块把打包数据远程发送出去,通过基站传送到手机上,从而对远距离现场情况实时监测。并配备继电器、可控硅、温度传感器、门磁开关、电磁阀、酒精传感器等达到设备自动控制、环境监测、自动灭火功能。

A System with Alarm of GSM Remote Monitoring Based On the Radio Frequency Card
Abstract :This system mainly consists of STC89C53 MCU, GSM module TC35, ultrasonic module, infrared emission receiver module, ID cards, NRF2401 and other modules, with reliable and mature GSM work, it not only can directly send the latest situation to your mobile phone screen in the way of the most efficient short messages or phone, but also can control the home electrical equipment by automatically dialing with mobile phone or text messaging .The system mainly uses ultrasonic sensors, smoke sensors, vibration sensors, infrared detection sensors, it is an on-work of anti-theft system, that is consisted of multiple short-range and high-munication module called NRF2401,which transmit real-time data, and then monitor the real on-site situation of long distance in the passage of reporting the scene by the GSM module . Moreover ,it can put the function of automation ,environmental monitoring and automatic fire-extinguishing into effect ,which is equipped with relays, SCR, temperature sensor, ic switch, solenoid valve and alcohol sensors.
Keywords:munication; RF cards; munication; intelligent monitoring and control; infrared modulation;
