基于物联网的家庭照明系统研制

Family Lighting System Development Based on Internet of Things

该文主要介绍了一种基于物联网技术的家庭照明系统的研制,采用Nordic公司的无线射频芯片nRF24LE1芯片（内置8051处理器核）作为物联网的硬件实体,将家庭里的电灯组合成一个系统,采用密码算法进行相互通信,主控制器采用ARM处理器对系统进行总体控制,同时内置GSM通信模块SIM300C,使得用户也可以通过手机短信的方式随时随地了解系统整体情况,并对整个系统进行控制;在软件方面,我们使用自定义的协议实现主控制器与终端设备的通信;另外,我们使用密码表方法实现了不同系统的隔离。

This paper mainly introduces a family lighting system development based on Internet of Things.By using Internet of Things tech nology and wireless communication technology,we connect all the lights inside a family into a network through a unified management of the master controller.For wireless communications,we adopt radio frequency chip of Nordic company’s NRF24L01 and NRF24LE1（built-in 8051 processor core）.The master controller adopts ARM processor LPC2368 to overall control the system.The master controller has internal GSM communication module-SIM300C,so users can also send control messages to the main controller through SMS,the main controller will analyze the messages and then send control commands to terminal equipments.In software communication aspect,we use user-defined protocol to realize the communication between the master controller and terminal equipments.In addition,to assure reli able and stable communication,we also design a cryptographic algorithm and state machine thought.
