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>>

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>>

pointIdsWithLogic

Mandatory

String

The aggregation logic with measurement point ID. The supported aggregation calculation methods include count, avg, sum, max, min, first, and last. The time range for the aggregation query is (startTime, endTime), that is, the aggregation operand contains the data at the time of startTime, but does not contain the data at the time of endTime. Format: Function(pointId), e.g. sum(pointId). How to get measurement point ID>>

interval

Mandatory

Integer

The time interval for the aggregation algorithm to work. The range is 0-1440, calculated in minutes. If the interval value is 0, the measurement point has no aggregation logic; if the interval value is greater than 0, the measurement point must have the aggregation logic.

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.

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>>

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

{
        "count(ai_point)": 4,
        "assetId": "Ps4PViva",
        "timestamp": 1587312600000,
        "localtime": "2020-04-20 00:10:00"
}

Parameters

Name

Data Type

Description

pointIdsWithLogic

Double

This parameter is a variable, representing the identifier and data of the measurement point (with or without aggregation logic)

assetId

String

The asset ID.

timestamp

Long

The data timestamp (UNIX time, accurate to the second).

localtime

String

The data timestamp in local time format (accurate to the second). The value of the localTimeFormat parameter determines whether the local time value includes the time zone information.
