Problems solved by technology

As a result, when the number of stored files is large and are basically small files of 1K or 2K, the waste of storage space is very serious, and the overall storage efficiency is often less than 50%, which cannot meet the needs of data storage.
For this reason, have to adopt the large-capacity data memory that increases device cost
[0003] In addition, due to the lack of file backup and recovery mechanisms in the above-mentioned existing devices, data security is not good
When individual bytes in the file are abnormal (such as byte mutation due to environmental influences—0 becomes 1, 1 becomes 0), it is likely to cause the overall damage of the file. Once the damaged file belongs to the system class or is particularly important Parameter files, which may lead to serious consequences including the automatic device entering the wrong operation mode

Embodiment 1

[0042] In this embodiment, the method for improving the data storage efficiency and security of the intelligent network load interactive terminal includes the following steps:

[0043] Step 1, storage step

[0044] Step 1.1, divide the storage space into regular area and backup area;

[0045]Step 1.2: Create a secondary index file that saves the information stored in each logical file in the physical file, including name, address, length, and checksum (see figure 2 );

[0046] Step 1.3. For the secondary index file, extract the logical file name, sort it alphabetically, and establish a primary index file that reflects the corresponding subscript position in the secondary index file (see figure 1 ), stored in memory;

[0047] Step 1.4, store the logical files smaller than 50% of the physical files on the physical files in the regular area in the form of at least two closely stored on the same physical file; at the same time, store the logical files smaller than 50% of the p...

Abstract

The invention relates to a method of improving data storage efficiency and security of an intelligent network load interaction terminal, and belongs to the technical field of network communication. The method includes the steps of a storage step, an extraction step, regular reading, data recovery and network asking for help. Logical files are stored in physical files in a manner of gathering partsinto a whole, and thus storage capacity is significantly increased; and a first-level index file and a second-level index file are also introduced, and thus finding efficiency of data is effectivelyguaranteed. In addition, a multi-guarantee mechanism of CRC32 checking, compressed backing-up and network asking for help is also adopted, the method has extremely high data recovery capability, and the security of data storage and reliability of terminal running are ensured.

Description

technical field [0001] The invention relates to a method for improving data storage efficiency and security, in particular to a method for improving data storage efficiency and security of an intelligent network load interactive terminal, which belongs to the technical field of network communication. Background technique [0002] The intelligent grid-load interactive system is a real-time measurement and control system for the collection and control of electrical quantities of multiple power supply and distribution lines based on high-speed network communication for the purpose of quick response (see application number 201310124359.5, name "A Network Based on Smart Grid The Chinese patent document of "Dutch Interactive Multi-Dimensional Operating System"), which contains a large number of embedded intelligent automation devices. In order to reduce costs, the size of the data memory block used by these devices is generally 4K, and the minimum processing unit of mainstream fil...
