基于ZigBee的智能家居设备设计

摘要

According to the shortcoming of wiring dififculties, poor mobility, high-cost maintenance and so on in the traditional smart home, a smart home scheme based on Zigee wireless sensor network technology is designed. The whole system regards S3C2440 as the server combining with the ZigBee network technology to control the sub-node terminals by the coordinator. The sub-node terminals contain the common devices such as the smart home environment information real-time display, ten-level dimming and simulate curtain are controlled by STM32. The current date(including lunar calendar and weekdays), time and room temperature are displayed on the LCD in real time, and the lighting intensity and the degree of the curtain’s closure can be controlled between 0 and 100% by sending instructions to the coordinator on the smart phone after veriifcation.%针对传统智能家居存在布线困难、移动性差、维护成本高等缺点，提出了一种基于ZigBee无线传感网技术的智能家居方案。整个系统以S3C2440作为服务器，结合ZigBee组网技术，实现了通过协调器控制子节点终端。具体的子节点终端设备由STM32单片机控制，设备包括家居环境信息实时显示、十级调光和模拟窗帘。经测试验证，系统在液晶屏上实时显示当前日期（包括阴历和星期）、时间以及室内温度；通过在智能手机终端界面发送指令，灯光亮度和窗帘闭合度实现0~100%可调。
