创建物 AWS 联网 FleetWise 活动

要在 S3 存储桶中存储车辆数据，请选择 Amazon S3。S3 是一种对象存储服务，可将数据以对象形式存储在存储桶中。有关更多信息，请参阅《亚马逊简单存储服务用户指南》中的创建、配置和使用 Amazon S3 存储桶。

S3 优化了数据存储成本，并提供了其他车辆数据使用机制，例如数据湖、集中式数据存储、数据处理管道和分析。您可以使用 S3 存储数据以进行批处理和分析。例如，您可以为机器学习 (ML) 模型创建硬刹车事件报告。传入的车辆数据在交付前会缓冲 10 分钟。

在 S3 目标设置中，执行以下操作：

要将车辆数据存储在 Timestream 表中，请选择 Amazon Timestream。您可以使用 Timestream 查询车辆数据，以便识别趋势和模式。例如，您可以使用 Timestream 来创建车辆燃油水平警报。传入的车辆数据将近乎实时地传输到 Timestream。有关更多信息，请参阅什么是亚马逊 Time stream？ 在《亚马逊 Timestream 开发者指南》中。

在 Timestream 表设置中，执行以下操作：

在 Timestream 的服务访问权限中，执行以下操作：

要向MQTT主题发送车辆数据，请选择MQTT主题。

通过MQTT消息发送的车辆数据以近乎实时的方式传送，允许您使用规则采取行动，或将数据路由到其他目的地。有关使用的更多信息MQTT，请参阅《AWS IoT Core 开发者指南》 AWS IoT中的设备通信协议和规则。
