Embodiment 1

[0036] Embodiment 1. This embodiment proposes a bare disk storage method for smart substation network messages, including the following steps:

[0037] Hard disk partition steps, such as figure 1 As shown, it is a schematic diagram of the hard disk storage data structure. The hard disk is divided into several data blocks BLOCK, respectively BLOCK1, BLOCK2..., each storage block BLOCK contains several file blocks F_M, respectively F_M1, F_M2..., for each data block Blocks and file blocks are sequentially numbered, such as 0,1,2,3....

[0038] The data block function division step, in each data block, the data block numbered 0 is fixedly selected as the metadata block, which is used to store the metadata of the file block, and the remaining data blocks are used to store the network message data of the file block, which is the data block for the report Text data blocks; By dividing data blocks according to functions, metadata and network message data are stored separately. You o...

Abstract

The present invention provides a method for storing network messages of an intelligent substation in a bare disk. The method comprises the following steps of: a hard disk partitioning step of dividing a hard disk into a plurality of data blocks; a data block function partitioning step; by taking the types of the network messages as partitioning bases, assigning the data block matched with the occupied space of the network message for each type of the network message; a memory allocating step of allocating a memory for each type of the network message; and a network message storing step. The storage method utilizes the hard disk evenly, which facilitates the security and stability of a hard disk system. The network messages are stored separately by type, which shortens traversal time of later retrieval. A separate storage space design causes fault tolerance and security to be improved.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a bare disk storage method for intelligent substation network messages. Background technique [0002] The network messages of the smart substation are generated 7×24 hours, so the corresponding analysis and processing devices in the substation must be in the mode of uninterrupted operation. In addition, the online storage traffic of network packets is huge, and the storage function requirements are relatively simple. Under the current technical conditions, the storage medium of this massive data must rely on the hard disk. In smart substations, due to the use of networking and full digitalization, electrical equipment is connected to the network, and the interaction of electrical equipment is transmitted by network messages. There are five most common types of network messages: [0003] 1) SV network messages are generated continuously at high frequency, accoun...
