物的模型TSL
更新时间:2019-06-17 15:27:41
TSL概念
物模型是对设备是什么,能做什么的描述,包括设备身份标识、连接状态、描述信息,以及设备的属性(properties)、服务(services)、事件(events),后三者构成了设备的功能定义。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)。
产品功能
在每个产品中,都需要定义一套物的模型,即“功能定义”。每个产品有两类功能:
功能类型 | 描述 |
---|---|
标准功能 | 根据ICA数据标准,平台为每个品类创建了默认的标准功能,分为可选和必选 |
自定义功能 | 如果标准功能不符合您的设备特征,您也可以自定义功能 |
而功能的组成为三要素:属性、事件、服务。分别用于:
功能三要素 | 描述 |
---|---|
属性 | 用于描述设备运行时的状态,支持状态读取和设置,如开关、温度、颜色等。 |
服务 | 用于实现更复杂的业务逻辑,可包含输入参数和输出参数,可用于让设备执行某项定特定的任务。如烤箱的烘焙功能中,需要设定时间和温度等。 |
事件 | 用于描述设备运行时的事件,如瞬时性的通知信息,也可包含多个输出参数。如人体红外传感器识别到有人经过、空调上报了故障等。 |
功能审核
由于平台目前遵循ICA数据标准,所以自定义的部分需要平台审核,处理周期为1个工作日内,一般不会阻塞您的开发进展。在审核完成之前,平台暂无法使用未通过审核的自定义功能。审核期间,状态如下:
自动生成TSL
功能定义完成后,平台能够根据“标准功能” 和(通过审核后)“自定义功能”,自动生成一份Json格式的TSL。
