Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] In the embodiment of the present invention, a data storage method is implemented by controlling the data received at the same time to be saved in a file, and using a timeline to track the file.
[0034] figure 1 The flow of the data storage method provided by the embodiment of the present invention is shown, and the monitoring video data sent by a certain monitoring channel in the video monitoring system is saved as an example, which is described in detail as follows:
[0035] In step S101, when a trigger command is received, a time point including trigger time and data storage information ...

The invention is applied in the data processing field and provides a method for storing data, a method for reading the data and a system thereof. The method for storing the data comprises the following steps: generating a time point which comprises trigger time and data storage information on a corresponding time line when a trigger command is received, storing or stopping to store the received data into a file of current storage data according to the current storage state and the matching state of the trigger command, and updating the data storage information in the time point which is generated newly according to relevant information of the file. In the example of the invention, the method for storing the data is realized through controlling the data which is received on the same time to be stored in one file and through using the time line to track the file, a plurality of preservation operations to same data which is triggered by a plurality of trigger commands are avoided, and the spatial demand to a storage device and the storage device cost are lowered, which is convenient for inquiring.
Description
technical field [0001] The invention belongs to the field of data processing, and in particular relates to a data storage method, a data reading method and a system. Background technique [0002] In the field of security monitoring, it is necessary to save the surveillance video data on a network video server or a digital video recorder (Digital video recorder, DVR), so that the surveillance personnel can view it afterwards. Since a monitoring channel may trigger multiple recording strategies at the same time (such as the timer recording strategy set by the user, the motion detection alarm strategy, etc.), the system will save the recording data of the monitoring channel as Multiple video files increase the space occupancy rate of the storage device and increase the cost of the device. [0003] And when the client checks the historical video data of the monitoring channel through time-shifting, since there are multiple video files in a certain period of time, the system nee...
