Get Asset DI Data¶

Get the status change (DI) data of specified devices within a certain period.

The API captures the state of a particular asset over a period of time and returns only data that reflects changes in the state of the asset. For example, the raw data within a period is given as follows:

Time       Status
01:14    0
01:30    0
03:45    0
12:23    1
13:34    0
15:24    1
17:25    1

The returned results are as follows:

Time       Status
01:14    0
12:23    1
13:34    0
15:24    1

Note

The status data of specific assets may be represented by other integers. If there is no DI data at the start time of the request, it will trace back the last state value within the last 30 days from the start time. The data is returned with the timestamp of the request start time.

Using GET Method¶

Request Format¶

GET https://{apigw-address}/tsdb-service/v2.0/di

Request Parameters (URI)¶

Name	Location (Path/Query)	Mandatory/Optional	Data Type	Description
orgId	Query	Mandatory	String	The organization ID which the asset belongs to. How to get organization ID>>
modelId	Query	Optional	String	The model ID. How to get model ID>>
assetIds	Query	Mandatory	String	The asset ID. Supports the query of multiple asset IDs, separated by commas. How to get asset ID>>
measurepoints	Query	Mandatory	String	The measurement point ID. Supports the query of multiple measurement point IDs, separated by commas. How to get measurement point ID>>
startTime	Query	Mandatory	String	The start time of the sampling data, where both UTC and local time formats are supported. For UTC time format, the application will query all the asset data by the unified start timestamp and end timestamp. Timezone information is required for the UTC time format: 2019-06-01T00:00:00+08:00. For local time format, the application will query the asset data by the local time of where the device is located. Its format is: YYYY-MM-DD HH:MM:SS.
endTime	Query	Mandatory	String	The end time of the sampling data. Its format must be consistent with `startTime`.
accessKey	Query	Optional	String	The service account for authentication purposes. How to get the accessKey>>
localTimeAccuracy	Query	Optional	Boolean	true = query returns data with millisecond time stamp false (default) = query returns data without millisecond time stamp
autoInterpolate	Query	Optional	Boolean	true = query the latest status data in the past if no data is found at the query start time false (default) = do not query the latest status data in the past if no data is found at the query start time

Response Parameters ¶

Name	Data Type	Description
data	List<JSONObject>	The list of asset data. The data returned for a single point of a single device is sorted by the data timestamp in ascending order. For more information, see items

items¶

Sample¶

{
        "assetId": "yourAssetId",
        "timestamp": 1560249312446,
        "yourPointId": 1,
        "localtime": "6/11/2019 6:35:12 PM"
}

Parameters¶

Name	Data Type	Description
assetId	String	The asset ID.
timestamp	Long	The data timestamp (UNIX time, accurate to the second).
pointId	Integer	This parameter is a variable, representing the identifier and data of the measurement point.
localtime	String	The data timestamp in local time format (accurate to the second). If UTC time format is used when specifying the `statTime` and `endtime`, this value will be null.
