AWS IoT FleetWise 不再向新客戶開放。現有的 AWS IoT FleetWise 客戶可以繼續使用 服務。[上的連線行動性指南 AWS](https://aws.amazon.com/solutions/guidance/connected-mobility-on-aws/)提供如何為連線行動解決方案開發和部署模組化服務的指引，這些解決方案可用於實現與 AWS IoT FleetWise 同等的功能。

# 建立 AWS IoT FleetWise 訊號目錄
<a name="create-signal-catalog"></a>

您可以使用 [CreateSignalCatalog](https://docs.aws.amazon.com/iot-fleetwise/latest/APIReference/API_CreateSignalCatalog.html) API 操作來建立訊號目錄。下列範例使用 AWS CLI。

若要建立訊號目錄，請執行下列命令。

將 {{signal-catalog-configuration}} 取代為包含組態的 .json 檔案名稱。

```
aws iotfleetwise create-signal-catalog --cli-input-json file://{{signal-catalog-configuration}}.json
```

## 訊號目錄組態
<a name="signal-catalog-configuration"></a>
+ 將 {{signal-catalog-name}} 取代為您建立的訊號目錄名稱。
+ （選用） 將{{描述}}取代為描述，以協助您識別訊號目錄。

如需如何設定分支、屬性、感應器和致動器的詳細資訊，請參閱 [Configure AWS IoT FleetWise 訊號](define-signal.md)。
