Embodiment Construction
[0023] The formation of file fragments has various and complex reasons, which are related to the type and size of stored data, the nature of the storage device itself, and the frequency of data writing and deletion. At present, there is no good solution in the field of storage of complex types of data. For the single data storage of video recording data in the field of security and automobile monitoring, the existing method is to equip the storage device with a dedicated file management system, which can prevent file The generation of fragments, but due to the special file format, the data stored in it cannot be commonly used in other devices, and the cost is high, and it is not suitable for complex data storage environments.
[0024] The method and device provided by the invention are used to prevent the problem of file fragmentation in the case of single-type data storage, and can also be applied to complex data storage environments, and achieve the effect of universal file d...

The invention provides a data storage method and device. The method is applied on storage equipment which adopts a general file a management system, and is used for writing stored data by utilizing ways of pre-distributing spaces for data and overwriting data through detecting residual spaces of storage equipment. The provided data storage device comprises a detection module, a first pre-distribution module, a second pre-distribution module and a storage control module, wherein the detection module is used for detecting the residual spaces of storage equipment; the first pre-distribution module and the second pre-distribution module are used for creating files, distributing spaces for the files and adding identification information to the files; and the storage control module is used for controlling data writing. Through the method and device provided by the invention, file fragments are prevented from being generated in the process of storing the data to the storage equipment.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a data storage method and device. Background technique [0002] At present, in the fields of security monitoring and vehicle monitoring, it involves full-time audio and video recording requirements, limited by cost and technical issues, the recorded data will be continuously written and deleted in the storage device, and a large number of files will be generated in the process fragmentation, thereby reducing the efficiency and speed of the entire system, reducing the life of storage devices, and bringing security and stability risks to stored data. With the demand and popularity of high-definition, ultra-high-definition and multi-channel video recording, the above The problem will get worse. [0003] A method for defragmenting mobile terminal files is disclosed in the prior art. The method is to copy the data in the defragmentation area to another memory; then format the...
