模拟已经构造好的Json数据，三步完成设备数据接入到AIoTedge边缘计算平台。

一、视频步骤 #

二、页面分解步骤 #

第一步：单击导入 #

进入Node-Red，单击菜单中的【导入】按钮。

第二步：选择预置流程 #

在弹出的导入节点框中，选择【本地存储】，选择【模拟测试-随机生成温湿度-直连设备】，单击【导入】。

单击【导入】把流程，放入工作区的中间。

第三步：单击手动测试 #

当流程已经导入，首先将窗口切换到【调试】窗口，其次单击【部署】；

最后进行测试验证，单击【定时启动】前面的【方框】{这个为手动注入}。则会在右侧调试窗口中看到输出内容。

PS：单击一次，输出一次。
