摘要:
智能家居系统中以 AVR 为核心板,介绍了硬件模块设计、系统软件设计、传感器数据采集及硬件接口设计等部分。针对 Zigbee 网络传输速率不高的情况,为了提高数据传输速率,核心板与移动终端之间采用 WiFi 模块进行无线通信。 系统实现了家庭环境的温度管理、湿度管理、灯光管理、用电安全管理及烟雾检测与报警等功能。 经测试,在 30 m 范围内,无障碍环境下平均丢包率为 0. 049 6% ,有障碍环境下平均丢包率为 0. 161 6% ,无障碍及有障碍环境下系统的丢包率均低于5‰;节点数在 1 ~ 11 内,采用 WiFi 模块进行无线通信的数据传输速率为 9. 82 Mbps ~ 11 Mbps,采用 Zigbee 模块进行无线通信数据传输速率为 195 kbps ~ 249 kbps。 采用 WiFi 模块进行无线通信在设备节点满足智能家居需要的情况下,有效地提高了数据传输速率。
Abstract:
With the AVR as the core board in the smart home system,we introduce the hardware module design,system software design,sensor data acquisition and hardware interface design. Aiming at the condition of the Zigbee network transmission rate is not high,in order to improve the data transfer rate,the WiFi module is selected to communicate between the core board and the mobile terminals. The system realizes the functions of temperature management,humidity management, lighting management,electricity safety management and smoke detection and alarm. After the test,within the scope of 30 meter,the average packet loss rate was 0. 049 6% in barrier-free environment,the average packet loss rate was 0. 161 6% in the obstacle environment,the accessibility and obstacle environment system packet loss rate is less than 5‰. Number of nodes within 1 ~ 11,the wireless data transfer rate is 9. 82 ~ 11 Mbps by the WiFi module,the wireless data transfer rate is 195 ~ 249 kbps by Zigbee module. With the WiFi module for wireless communication in the device node under the condition of satisfying the needs of the smart home,data transfer rate is improved effectively.
