基于CC3200的可视化低功耗WiFi门铃设计与实现

Design and Implementation of Visual Low-power WiFi Door Bell Based on CC3200

针对当前无线门铃需要频繁更换电池的功耗性问题,提出了基于无线通信技术和物联网技术相结合的智能可视化低功耗WiFi门铃系统。该系统以带有片上WiFi功能的单片机CC3200为核心,搭载摄像头、OLED屏等外设,采用具有Android系统的智能手机为移动终端。结果表明,当无访客时门铃处于休眠状态,可大幅度降能耗;当访客到来时门铃从睡眠模式被唤醒,自动连接WiFi设备,主人可通过移动设备在App上接收音视频流数据,实现远程实时可视化对讲。

Aiming at the problem of power consumption of wireless doorbell which needs to change batteries frequently,an intelligent visual low-power WiFi doorbell system based on the combination of wireless communication technology and internet of things technology is proposed.Taking CC3200,a single chip computer with on-chip WiFi function,as the core,the system is equipped with cameras,OLED screens,et al.The mobile terminal is the smart phone with Android system.The results show that when there is no visitor,the doorbell is in a dormant state,which greatly reduces the power consumption;when the visitor arrives,the doorbell is woken up from sleep mode,automatically connects to the WiFi device,and the owner can use the mobile device to receive the audio and video streaming data on the App,thereby realizing remote real-time visual intercom.
