#物联网挑战赛#-智能教室小助手 简单

头像 阿琛 2023.05.29 115 4

项目介绍：

 

使用行空板作为主控板，通过摄像头识别二维码的方式统计作业收集情况，并将收集的结果显示在教室的大屏幕上。可以实时看到各科作业的收集情况，同时还能看到当前教室的光线亮度，噪音大小以及最新交作业的同学。实现智能教室小助手的功能。

制作过程：

 

在智能作业收集助手的作品基础上，增加了行空板的物联网部分。通过物联网将数据实时与大屏联通，从而实现了将统计结果显示在大屏上的效果。

 

步骤一：打开物联网终端

步骤二：在网页打开物联网终端，并设定相关的主题

步骤三：为行空板连接物联网，并订阅相关主题

步骤四：设计大屏的显示效果，并为各模块绑定订阅数据

通过以上四步，就能够完成大屏与行空板的数据交互了，配置很简单，效果也非常棒！不仅能够将计算后的结果数据通过物联网同步到大屏，也可以把行空板监测到的实时数据同步过来，比如光线亮度和噪音等。从而实现一个智慧班级的管理功能。
