摘要
在此介绍一种基于Android平台的家用无线防盗报警系统,其不仅实现低成本检测、显示和报警,而且能通过串口Wi Fi设备将系统数据无线传输到用户的智能手机上,实现远程无线控制。系统采用超声波测距模块、振动检测模块和红外对射电路实现自动检测功能,采用蜂鸣器和LED实现声光报警功能,以内置精简指令集RISC的AVR单片机作为数据处理中心,通过异步串行收发器USART将系统状态数据发送至HLK-RM04模块,该模块内置TCP/IP协议栈实现用户串口、以太网、Wi Fi接口之间数据的转换和传输。系统还通过对Android手机应用程序编程,使用户在智能手机上实现AVR单片机与智能手机之间数据传输,实现对整个系统的设置与控制。
The household antitheft alarm system based on Android platform and combined with the microcontroller not only can achieve lowcost detection,display and alarm,but also can transmit the system data to the users’intelligent mobile phone in wireless transmission mode through the serial port WIFI equipment, and realize remote wireless control. The ultrasonic ranging module,vibration detection module and infrared emission circuit are used in the system to realize automatic detection function. The buzzer and LED are adopted to achieve sound and light alarm function. The AVR single chip microcomputer with builtin reduced instruction set is taken as data processing center. The system status data is sent to the module LAKRMO4 through the asynchronous serial transceiver USART. The TCP/IP protocol stack is built in the module to realize data transmission and conversion among the user serial port,Ethernet and WIFI interface. Through programming of Android mobile phone application program,the user can achieve data transmission between AVR SCM and intelligent mobile phone in intelligent mobile phone,and realize setting and control of the whole system.
