Description

Technical Field

[0001] The utility model relates to the technical field of computers, in particular to a rapid backup and recovery system for power background computers. Background Art

[0002] As the power system is developing rapidly towards high reliability, high automation and high information level, the monitoring of power grid has become a key issue that is highly valued at home and abroad, especially the monitoring system plays an important role in control and monitoring in the power system. The power background monitoring system collects relevant telemetry, telesignaling and SOE data to complete monitoring, control and early warning, which greatly improves the reliability and safety of substation operation, improves the power supply quality, and realizes the monitoring and management of substation power supply and distribution system.

[0003] The power background monitoring system can complete the functions of comprehensive protection, data collection of multi-function instruments, remote control of equipment, and the four remote functions of telemetry, telesignaling, remote control, and remote adjustment. It reduces the inspection workload of operators and improves the safety and reliability of the automated operation of substations and distribution rooms.

[0004] At present, the power background monitoring system is based on computers, communication equipment, and measurement and control units. It can form any complex monitoring system with detection and control equipment. The continuous operation reliability of the power background computer system is particularly important. When the computer cannot recover from a serious fault and crashes, the entire power background system will stop working. Maintenance personnel will need a long time to reinstall the system and restart and recover on site, which may cause great unforeseen damage to the operation of the power system.

[0005] The utility model aims to provide a rapid backup and recovery system for power background computers in view of the deficiencies of the above prior art.

[0006] The technical solution adopted by the utility model is: a rapid backup and recovery system for a power background computer, comprising a power background computer, wherein the power background computer is connected to a solid-state hard disk and a backup and recovery host, and the solid-state hard disk having a first partition and a second partition is connected to the backup and recovery host; the first partition of the solid-state hard disk is a system storage area for the operation of the power background computer, and stores its operating system and system files, and the second partition of the solid-state hard disk is used to store backup and recovery data of the first partition, and the backup and recovery host can copy the data of the first partition to the second partition for data backup, and can also copy the data of the second partition to the first partition for data recovery.

[0007] Furthermore, the power background computer only runs on the first partition of the solid state drive and cannot access the second partition of the solid state drive, thereby achieving effective isolation protection for the backup and recovery data of the second partition.

[0008] Furthermore, the power background computer and the backup recovery host operate independently of each other and are provided with respective independent power supplies for power supply.

[0009] Furthermore, the backup and recovery host is an embedded computer and is provided with an independent UPS power supply. The embedded computer can run independently, which improves the reliability of system backup and recovery.

[0010] Furthermore, it is characterized in that the backup and recovery host is connected to a remote management computer, which can perform remote and rapid data backup and recovery operations.

[0011] The beneficial effect of the utility model is that the utility model is provided with a solid state hard disk with a first partition and a second partition, the power background computer and the backup recovery host are independently operated, the power background computer only operates on the first partition of the solid state hard disk and cannot access the second partition of the solid state hard disk, the backup data of the second partition can be effectively isolated and protected, and the backup recovery host can copy the data of the first partition to the second partition for data backup, and can also copy the data of the second partition to the first partition for data recovery. When the system of the power background computer is down, it can be restored in time through the solid state hard disk, which greatly shortens the business recovery time; at the same time, the embedded host is controlled by the command of the remote management platform, and the computer system can be remotely backed up / restored through the remote management computer, without the need for maintenance personnel to arrive at the site, and the normal operation of the power background system can be quickly and efficiently restored, and the operating status of the power background computer and the backup recovery status after the failure are monitored, which greatly improves the reliability of the operation of the entire power background system and effectively avoids the harm caused by computer failures to the normal operation of the power system.
