Embodiment Construction

[0034] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] Such as figure 1 As shown, it is a flow chart of a preferred embodiment of the method for updating and storing data of smart city video data in the present invention. In the data update storage method of this embodiment, there are video data collection steps, video data storage steps, and data update storage control steps, and the video data collection steps and video data storage steps belong to the existing framework. The video data acquisition step is mainly to collect the video data of each camera related to the system in the city; the video data storage step is mainly to control the writing of video data on the data storage area, and also read the data when the user calls the video data control, but in the ...

Abstract

The invention discloses a multi-point coordinated updating and storing method and system for smart city video data. The system comprises a data updating and storing control layer located between a video data acquisition layer and a video data storing layer, and the data updating and storing control layer determines associated cameras in all cameras, segments updated video data in the associated cameras in a main storage space according to time periods to obtain corresponding video segments, selects data from the video segments corresponding to the associated cameras according to a preset rule and copies the selected data to corresponding backup spaces in a backup storage space to store the data. Accordingly, on the condition that the total volume of the storage spaces is invariable, by means of the method that the main storage space saves the video data in a preset time, and the backup storage space saves part of the key data before the preset time, the total data saving time is prolonged.

Description

technical field [0001] The invention relates to the field of data storage, and more specifically, to a method and system for multi-point cooperative update and storage of video data in a smart city. Background technique [0002] Smart cities are the development trend of cities in the future. The construction of smart cities requires the use of a large number of video cameras, based on the storage and processing of video images captured by these video cameras, to realize the intelligence of the city. In the existing architecture, the video data acquisition layer is responsible for collecting data, and the video data storage layer is responsible for storing the data of the video data acquisition layer. These video data are often stored on the server. Since the storage space on the server is fixed, these videos There is an upper limit (recorded as T days, such as 30 days) for the number of days that the video monitoring data of the camera is saved, and the number of days of the...
