基于ARM软核的智能家居无线传感器网络设计

设计并实现一种基于片上系统(System on Chip,SoC)的智能家居无线传感器网络(Wireless Sensor Network,WSN)。根据IEEE 802.15.4标准提出一种智能家居体系的WSN传输层通信协议,通过高级精简指令集微处理器(Advanced RISC Machine,ARM)软核处理器搭建基于现场可编程门阵列(Field-Programmable Gate Array,FPGA)的硬件结构来实现中央控制单元,用C语言编程来实现该通信协议的主要功能,并在FPGA开发板上搭建电路平台进行验证。以温湿度传感器DHT11作为传感器子设备对WSN进行验证,实验结果表明,系统正确地实现了智能家居WSN的功能。

Design of mmart home wireless sensor network based on ARM soft core

A smart home wireless sensor network based on SoC(System on Chip) is designed and realized.According to IEEE 802.15.4 standard,a transport layer communication protocol of wireless sensor network aiming at smart home system is proposed.And the hardware structure of ARM(Advanced RISC Machine) soft core based on FPGA(Field-Programmable Gate Array) is designed to realize the central control unit.Also,C language is used to program so that the main function of the communication protocol can be realized.The system is simulated in NC-Verilog to check the validity of logic,and it is verified on the platform which is built by FPGA demo board to check the validity of the design.The wireless sensor network is verified by a temperature and humidity sensor called DHT11 as the sensor sub-device.The experimental results show that the designed system realizes the function of the smart home wireless sensor network correctly.
