Research And Implementation Of Smart Home Control System Based On The Internet Of Things Technology

The thesis studies the Internet of things technology, intelligent home control system, embedded control system, ZigBee gateway design. It realizes the perception of smart home system hardware modules which designs a set of embedded gateway control system and related hardware driver installation Settings. The smart home system hardware platform consists of 1 PC, ARM9 S3C2440 development board, ZigBee network control module, a smoke sensor module, infrared sensor module, the photosensitive sensor module etc. Software environment deploys 32-bit Windows 7 operating system, VM ware virtual machine software, Ubuntu 10.10 Linux operating system, Qt designing software and Z- track protocol stack.Through the study of smart home control technology, it has a more detailed understanding about the overall structure and operation principle of intelligent home control system and related key technologies. It plans clearly the main design process of the system hardware and software. The thesis designs the smart home system based on Internet of things technology which includes the curtain control, temperature and humidity control, smart home alarm, home care, RFID access control, etc. It builds a sensor network using ZigBee wireless sensor technology which could collection information of indoor temperature, smoke information, multiple sensor data. It exchange information through the ZigBee coordinator and center control modules. The Center control module uses ARM S3C2440 development board, which is responsible for receiving the monitoring information uploaded by coordinator. After processing, it will sent control commands to the actuator node, achieve the goal of control perception node.The thesis introduces the development of Internet of things intelligent household and the existing major technology. It introduces the existing mainstream wireless communication technology and embedded system application of smart home. It designs the Internet of things home networking scheme which makes up of ZigBee wireless RF module(CC2530 module chip of TI company), embedded control chip(ARM S3C2440) and SMS transceiver module(SIMCOM SIM300 module). It realizes the remote control of the sensing nodes. Smart home system software design process are introduced, including the development of embedded control system, ZigBee wireless network control programming, processing module by completing the center, ZigBee embedded gateway, sensor nodes information exchange between three parts, the purpose of smart home system control. Finally, it tests the system, including SMS transceiver, smoke alarm and display interface testing.
