1、I 无线家居监控系统无线家居监控系统 摘要:本系统是以 AT89S52 为现场控制器,以 ARM 主控制器,它们辅以 CC1100 无线通信模块、温度传感器 DS18B20、烟雾报警模块、PWM 调光模块组成,实现 温度信号的无线传输以及显示、亮度的无线传输显示和烟雾报警。系统使用 51 单片机采集温度,亮度和烟雾报警信息,然后通过 CC1100 无线模块将数据发射 到 ARM;ARM 通过 CC1100 无线模块接收数据然后显示温度和亮度、也可以通过触 摸屏来控制 51 单片机端的 LED 的亮度和对报警信号进行处理。 最终完成了温度、 亮度和烟雾信号的准确采集及 CC1100 的双向通讯,
2、实现对家居的安防和控制。 关键词:ARM9;S3C2440;DS18B20;CC1100;PWM 调光 Wireless home monitoring system Abstract: The system is based on AT89S52 site controller and based on the ARM host controller they are supplemented by CC1100 wireless communication module, temperature sensor DS18B20, smoke alarm module, PWM dimming
3、 modules, wireless transmission of temperature signals and display brightness wireless transmission display and smoke alarms. 51 single-chip system uses collecting temperature, brightness and smoke alarm information, and then through the CC1100 wireless module to data emission to the ARM; the ARM CC
4、1100 wireless module to receive data and then display the temperature and brightness, also can via the touch screen to control the brightness of the 51 single-chip side of the LED and alarm signal for processing. Finally to complete the two-way communication of accurate acquisition of temperature brightness and smoke signals.
