功能定义完成后,平台根据“标准功能” 和“自定义功能”,自动生成JSON格式的物模型。

前提条件

已完成标准功能和自定义功能的配置。

背景信息

物模型是对设备是什么,能做什么的描述,包括设备的属性(properties)、服务(services)、事件(events)等。阿里IoT通过定义一种物的描述语言来描述物模型,称之为 TSL(即 Thing Specification Language)。更多物模型介绍

操作步骤

  1. 进入产品-功能定义页面。
  2. 在产品功能定义中,单击查看物模型

    查看物模型
    物模型详情
  3. 单击导出模型文件,可以将JSON文件保存到本地。
