Design Of An Intelligent Home System Based On The Android System And Zigbee

Intelligent household is in recent years an emerging field, it incorporates wireless sensor network technology and computer technology. Intelligent household in the early stages in the development of the industry itself, with broad space for development. This project involved to wireless sensor network and automatic control technology, design a kind of intelligent household system the general structure and the software and hardware solutions. Specific content as follows:The architecture of a system and overall design:according to the existing zigbee technology, and choose CC2430 as wireless sensor network node, the core chip CC2430 connection sensor, constitute sensor network node. Node between the star network topology, intelligent household sensor networks composed. Node equipment can be within the state of household environment information collection and data pretreatment. The central node (central controller based on ARM CPU) is running Android system S3C2440 development board and the samsung was carrying CC2430 chip system. The system can follow-up expansion of mobile phones as control terminals. System functions:in intelligent household central controller to run the program, can monitor household environment condition; For some electrical operation realize intelligent automatic control and manual operation.System hardware design:hardware design including intelligent household central controller and child controller of two parts. Central controller selection will CC2430 chip system loading to samsung S3C2440 development board, design the central controller general diagram; The monitoring of the son controller sensors selection, design the sensor and CC2430 connection circuit, the typical home appliance to control circuit.System software parts:system software into bottom drivers and upper applications. Underlying driver aspects firstly introduces zigbee communication protocol, design the son CC2430 program of controller, the process is complete AD transform task, data pretreatment task, wireless transmitting/receiving task. Design the central controller CC2430 module on the wireless transmitting/receiving procedures, serial communication program; In the upper applications running on android system design of the application.
