Step By Step
物联网产品及设备的创建
1、创建产品
2、导入物模型

}注意： 替换自己产品的ProductKey
3、添加设备
IoT Studio绑定产品+设备
1、创建项目
2、项目创建完成后分别关联创建的产品和设备
3、新建业务服务
4、业务流程搭建
5、云数据库MySQL节点配置介绍
- 5.1 MySQL的版本
请使用MySQL5.7或MySQL5.6版本，其它版本兼容性会有问题，可能会出现连接异常。
- 5.2 参数配置
{
"table": "iotdevice1",
"rows": [
{
"CellSignalStrength": "{{query.props.CellSignalStrength.value}}",
"Distance": "{{query.props.Distance.value}}",
"Longitude": "{{query.props.GeoLocation.value.Latitude}}",
"Latitude": "{{query.props.GeoLocation.value.Longitude}}"
}
]
}也可以是（注意节点Id按照具体节点情况修改）：
{
"table": "iotdevice1",
"rows": [
{
"CellSignalStrength": "{{payload.props.CellSignalStrength.value}}",
"Distance": "{{query.props.Distance.value}}",
"Longitude": "{{query.props.GeoLocation.value.Latitude}}",
"Latitude": "{{node.node_339cdef0.props.GeoLocation.value.Longitude}}"
}
]
}payload表示上一个节点输出参数；query表示输入节点的参数；node.nodeId表示指定某一节点的输出参数。
- 5.3 MySQL建表语句
/*------- CREATE SQL---------*/
CREATE TABLE `iotdevice1` (
`CellSignalStrength` int(11) DEFAULT NULL,
`Distance` double DEFAULT NULL,
`Longitude` double DEFAULT NULL,
`Latitude` double DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8设备在线模拟测试
1、部署调试
2、数据流转查看
3、流程测试正常后，发布即可
