Storage system for network communication recording device of digital substation

Abstract

The invention discloses a storage system for a network communication recording device of a digital substation. The storage system comprises a main controller board module, a hard disk pack module and an IPMI (Intelligent Platform Management Interface) module, wherein the main controller board module is provided with an embedded processor, dual memories and an operation accelerator chip; software system modules are arranged in the dual memories; an operation system module of each software system module is used for running an guiding and loading program for the embedded processor, driving an embedded Linux operation system and introducing a Rootfs file system; a monitoring module is used for monitoring system operation, network link, chip temperature and voltage data of a module and providing the data to the outside through an IPMI specification; a storage control module is used for establishing, removing, restoring, reestablishing and monitoring a disk array of the hard disk pack module, carrying out operation management through a WEB management interface module and realizing NAS (Network Attached Storage) management and IPSAN (Internet Protocol Storage Area Network) management through a data access management module; a data tamper preventing module is used for preventing data from being illegally tampered; and the hard disk pack module is an RAID (Redundant Array of Independent Disk) 0 / 1 / 5 / 6 type disk array; and the IPMI module is used for monitoring the operation condition of the storage system and exporting monitoring data according to the IPMI specification.

Description

technical field [0001] The invention relates to a storage system for a digital substation network communication recording device, which is suitable for the special storage system of the digital substation network communication recording device based on the CPCI interface of NAS and IPSAN hybrid storage control. Background technique [0002] There are many problems in the process layer of the traditional integrated automatic substation: for example, the investment of the transformer is large, it occupies a large area, and it is complicated to cooperate with the secondary system; the information exchange is based on the hard wiring of the secondary cable, and the cable has electromagnetic interference and poor reliability. It often happens that the secondary equipment runs abnormally due to the electromagnetic interference of the cable; the information collected by the process layer equipment cannot be shared, etc. [0003] After adopting the digital substation, the process la...

Problems solved by technology

[0002] There are many problems in the process layer of the traditional integrated automatic substation: for example, the investment of the transformer is large, it occupies a large area, and it is complicated to cooperate with the secondary system; the information exchange is based on the hard wiring of the secondary cable, and the cable has electromagnetic interference and poor reliability. It often happens that the secondary equipment runs abnormally due to the electromagnetic interference of the cable; the information collected by the process layer equipment cannot be shared, etc.

[0008] 1. The resources of the screen cabinet in the digital substation are limited, and the installation space for the storage system is limited. The storage system should use the minimum number of hard disks while meeting the capacity requirements;

[0009] 2. The digital substation belongs to the harsh industrial environment, requiring no fan for the equipment in the station, and has high requirements for the system's damp heat performance;

[0010] 3. The data writing speed of the storage system does not meet certain substation configuration and traffic requirements under the network topology, resulting in congestion, resulting in incomplete message records;

[0011] 4. Since digital substations are mostly built in the field, the working environment of network communication recorders is relatively harsh, and there is a certain probability of damage to the disk of the storage system, resulting in data loss;

[0012] 5. The data protection level, failure recovery capability and service continuity cannot meet the requirements of the non-stop working mode of the network communication recording device;

[0013] 6. The stored data has been tampered with so that the original data cannot be provided;

[0014] 7. The background host is incompatible with the data access protocol of the storage system, and the data access bandwidth is insufficient
