Request Parameters (Body)

Name

Mandatory/Optional

Data Type

Description

modelId

Optional

String

The model ID. How to get model ID>>

assetIds

Mandatory

String

The asset ID. Supports the query of multiple asset IDs, separated by commas. How to get asset ID>>

pointIds

Mandatory

String

The measurement point ID. Supports the query of multiple measurement point IDs, separated by commas. How to get measurement point ID>>

startTime

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

Mandatory

String

The end time of the sampling data. Its format must be consistent with startTime.

pageSize

Optional

Integer

The upper limit of the returned records in a single page for a single measurement point of a single device, which is 1,000 by default.

withQuality

Optional

Boolean

  • true = the quality indicator is included in the response

  • false = the quality indicator is not included in the response

localTimeAccuracy

Optional

Boolean

  • true = query returns data with millisecond time stamp

  • false (default) = query returns data without millisecond time stamp

localTimeFormat

Optional

Integer

Specify whether the local time value includes time zone information of devices. 0 (default): without time zone information; 1: with time zone information.

itemFormat

Optional

Integer

Specify the displaying format of the returned device data. Available options are 0, 1, and 2. For the example of each displaying format, see Item Format Example>>

boundaryType

Optional

String

Specify the type/scope of data to be queried if data is stored after compression. Available options are: inside (query compressed raw data only, default), outside (query compressed raw data and data records before the specified start time and after the end time), interpolated (query compressed raw data and interpolated data records at the specified start time and end time), and sample (return interpolated data records by specified time interval and algorithm within the specified start time and end time). The interpolated data can be used for making data in TSDB complete based on business needs.

interval

Optional

Integer

For boundaryType=sample, specify the time interval for generating the interpolated data records. The default value is 60, in seconds.

interpolation

Optional

String

For boundaryType=sample, specify the algorithm for generating the interpolated data records. Available options are: linear (linear interpolation, default), previous (prvious value interpolation), near (near value interpolation), after (next value interpolation). For detailed information about the algorithm, see Data Record Interpolation Algorithm>>
