# 使用 BatchUpdateDetector 更新 AWS IoT Events 偵測器模型
<a name="iotevents-commented-example-batch-update-detector"></a>

您可以使用 `BatchUpdateDetector`操作將偵測器執行個體置於已知狀態，包括計時器和變數值。在下列範例中， `BatchUpdateDetector`操作會重設溫度監控和控制下區域的操作參數。此操作可讓您執行此操作，而無需刪除、重新建立或更新偵測器模型。

CLI 命令：

```
aws iotevents-data batch-update-detector --cli-input-json file://areaDM.BUD.json
```

檔案： `areaDM.BUD.json`
