Embodiment Construction

[0087]In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0088] Before explaining the embodiment of the present invention in detail, some key terms involved in the embodiment of the present invention are explained first:

[0089] Unix timestamp: or Unix time (Unix time), POSIX time (POSIXtime), is a time representation, defined as from January 1, 1980, 00:00:00 GMT The total number of seconds so far.

[0090] Daylight Saving Time: Daylight Saving Time is also called Daylight Saving Time, Daylight Saving Time, and Daylight Saving Time. It is a local time system artificially stipulated to save energy. Usually, in summer when the dawn is relatively early, the time bar is artificially advanced by one hour, causing local Daylight saving time differs from winter time by one hour. Each country tha...

Abstract

The invention discloses a data management method, device and system, and belongs to the field of data processing. The method comprises the steps that a data query request of a terminal is received, the data query request carries an identifier, first starting time and first ending time of front-end equipment, the time type of the first starting time and the first ending time is standard time, and the standard time is the time type of the starting time and the ending time of data storage of a server; according to the identifier of the front-end equipment, the first start time and the first end time, target data collected by the front-end equipment, first time difference information and the start time and the end time of the target data are acquired, and the first time difference informationis used for indicating the time difference between the time zone time of the front-end equipment in the first time period and the standard time; and the target data, the first time difference information and the start time and the end time of the target data are sent to the terminal. According to the invention, the data management requirements of the front-end equipment in a plurality of time zones can be met.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data management method, device and system. Background technique [0002] In the field of video surveillance and storage, there may be multiple time zone scenarios, such as terminals used by users and servers used to provide storage services in multiple time zones, or front-end devices used to collect video data in multiple time zones, no matter where they are Multiple time zone scenarios will generate data management requirements in multiple time zone scenarios. [0003] At present, in related technologies, the time when the server stores video data adopts standard time, that is, UTC (Coordinated Universal Time, Coordinated Universal Time) time or Unix time stamp. The front-end device and the server are in the same time zone. When the terminal performs a query operation on the video data collected by the front-end device, the user can enter the start time and end time of...
