Example one
Fig. 1 is a flowchart of a fault emergency method according to an embodiment of the present invention, where the embodiment is applicable to a substation monitoring situation, the method may be performed by a fault emergency device, which may be implemented in the form of hardware and/or software, and the fault emergency device may be configured in a computing device. As shown in fig. 1, the method includes:
s110, for the monitoring subsystems corresponding to the transformer substations, when a fault emergency request corresponding to the current monitoring subsystem is received, the server host corresponding to the current monitoring subsystem is determined.
The monitoring subsystem can be understood as a system for monitoring the operation of the transformer substation so as to ensure the safe operation of the power grid. The fault emergency request may be an instruction for instructing execution of a fault emergency. The server host has a capability of running a plurality of virtual machines, for example, the server host may be a rack server, or may also be a blade server or a tower server, and the configuration of the server host may be: the dominant frequency is greater than 2GHz, such as 2.9GHz, the number of cores is greater than 8, such as 16 cores, a DDR (Double Data Rate, double Data synchronous dynamic random access memory) memory is greater than 128G, an ECC (error correction code) memory error correction technology and a disk array technology (RAID-5) are supported, the network is provided with 4 gigabit network ports, 8 PCle 4.0 high-speed channels and 16 2.5-inch hard disks, an optical fiber Ethernet card configured with 1000Mbps is connected with a substation A, B network, and the network mode adopts NAT network address conversion. It should be noted that the type and configuration of the server host can be determined by a technician according to actual working conditions. It should be further noted that the fault emergency method adopted by each monitoring subsystem is the same, so that any one of the monitoring subsystems is explained as the current monitoring subsystem.
In this embodiment, when it is detected that the current monitoring subsystem fails, it may be considered that a failure emergency request is received, and at this time, a server host corresponding to the current monitoring subsystem needs to be confirmed, so that the application data in the current monitoring subsystem is run based on a virtual machine on the server host, and the transformer substation is monitored in time. For example, when a certain substation, such as the a station background monitoring subsystem, has a fault (including system poisoning, downtime, password locking, and the like), the user may establish a connection between the a station network and the server host corresponding to the a station, so that the server host invokes the system execution program corresponding to the a station monitoring subsystem.
It should be noted that, in order to improve the intelligence and the rapidity of the fault emergency, when the fault emergency request corresponding to the current monitoring subsystem is received, in the process of determining the server host corresponding to the current monitoring subsystem, the fault emergency request may be generated when the current monitoring subsystem is detected to have a fault; analyzing the fault emergency request to obtain a host identification carried on the fault emergency request; and determining a server host corresponding to the host identifier, and establishing communication connection between the current monitoring subsystem and the server host so that the server host calls system standby data from the current monitoring subsystem.
Wherein the host identity can be used to characterize the uniqueness of the server host. The system backup data may be backup data of an application in the monitoring subsystem.
Specifically, when a fault of the current monitoring subsystem is detected, a fault emergency request may be generated, and the fault emergency request may be analyzed to obtain a host identifier carried in the fault emergency request. And determining a server host corresponding to the current monitoring subsystem based on the host identifier, and establishing communication connection between the current monitoring subsystem and the server host based on the network card so that the server host can call system standby data from the current monitoring subsystem.
And S120, calling system standby data corresponding to the current monitoring subsystem based on the server host, and placing the system standby data on a target virtual machine corresponding to the current monitoring subsystem for running so as to monitor a corresponding transformer substation based on the running target virtual machine.
The server host comprises at least one virtual machine to be used. The virtual machine is constructed through virtualization software through hardware virtualization, and an operating system of the virtual machine can be a Linux operating system and can well run an application program of the substation monitoring subsystem. The virtualization software may be a VirtualBox, VMware, virtualPC, KVM-x86 or the like.
In this embodiment, after the communication connection between the current monitoring subsystem and the server host is established, the server host may be used to retrieve the system standby data corresponding to the current monitoring subsystem, and place the system standby data on the target virtual machine corresponding to the current monitoring subsystem for operation. For example, after the communication connection is normal, the login server host system calls system standby data such as background system software and backup data of the station A to run on a target virtual machine configured in a corresponding environment, so that switching of a background monitoring system is realized, and a corresponding transformer substation is monitored. At the moment, the function executed by the target virtual machine is equivalent to the function executed when the current monitoring subsystem normally operates, so that when the current monitoring subsystem breaks down, normal monitoring in the transformer substation is still guaranteed, and the safe operation of the transformer substation is guaranteed.
It should be noted that, in order to improve the accuracy and the security of the system backup data storage, the system backup data of the current monitoring subsystem may be stored in the data storage module associated with the current monitoring subsystem, so as to be called from the corresponding data storage module when the server host calls the system backup data corresponding to the current monitoring subsystem.
Optionally, invoking system standby data corresponding to the current monitoring subsystem based on the server host includes: determining a data backup hard disk corresponding to the current monitoring subsystem; and calling system standby data from the data backup hard disk based on the server host.
The system standby data comprises an application program. The storage capacity of the data backup hard disk can be larger than 16TB, the data backup hard disk is doubly configured with the disk arrays with the same capacity, the data backup hard disk is installed in a transformer substation, and when the monitoring subsystem is not in fault, the data backup hard disk is in communication connection with the in-station monitoring subsystem and used for storing application programs, system data and the like of the monitoring subsystem, and the data are used as system standby data.
In this embodiment, a communication connection between the server host and the data backup hard disk corresponding to the current monitoring subsystem may be established, and the system backup data may be retrieved from the data backup hard disk, so as to place the system backup data on the target virtual machine for operation.
It should be noted that, in order to ensure that the system backup data is most suitable for the current monitoring subsystem and that the program data of the latest version of the current monitoring subsystem is running on the target virtual machine in the event of a failure emergency, a communication connection between the current monitoring subsystem and the data backup hard disk may be established, so that when the data backup hard disk detects that the application data in the current monitoring subsystem is updated, the data backup hard disk determines the update data, updates the system backup data based on the update data, and causes the server host to retrieve the updated system backup data from the data storage device.
In this embodiment, the current monitoring subsystem and the data backup hard disk may be in real-time communication connection, the data backup hard disk may perform data update detection on the current monitoring subsystem at intervals of a time period, and when it is detected that application data in the current monitoring subsystem is updated, the updated data is backed up and stored, so that the update of the system backup data is realized. For example, the data backup hard disk is set with an interval time T to update, backup and store the application program and the backup data in the current monitoring subsystem, so that the server host retrieves the updated real-time system backup data from the data storage device.
It should be noted that, in order to reduce the storage pressure of the data in the data backup hard disk, when it is detected that the system backup data in the data backup hard disk occupies a large amount of memory, some old data may be deleted to ensure the normal operation of the data backup hard disk.
Optionally, the method further includes: determining the proportion of the standby data based on the system standby data in the data backup hard disk and the hard disk space of the data backup hard disk; if the system standby data proportion exceeds a first preset proportion and does not reach a second preset proportion, generating storage prompt information; and if the system standby data proportion exceeds a second preset proportion, determining standby data to be released from the system standby data and deleting the standby data.
Wherein the standby data to be released is determined based on the time information when the standby data is received. The storage prompt information can be used for representing the memory condition of the data backup hard disk.
In this embodiment, the ratio of the system spare data in the data backup hard disk to the hard disk space of the data backup hard disk may be calculated as the spare data ratio. When the system standby data percentage exceeds a first preset percentage (for example, 60%) and does not reach a second preset percentage (for example, 90%), a storage prompt message, such as pop-up window information about exceeding a load, or a memory warning light prompt message, may be generated. When the system spare data percentage exceeds a second preset percentage (for example, 80%), it may be indicated that there are few idle controls remaining in the hard disk space, and at this time, the spare data that is received for a long time may be used as the spare data to be released and deleted from the data backup hard disk.
For example, the data backup hard disk may be constructed based on a NAS storage disk, for example, the storage capacity of the NAS disk is 16T, and another disk array with a capacity of 16T is configured in a double-copy manner for backup in case of a failure of the main storage. A dynamic storage program and a capacity management program can be arranged in the data backup hard disk to realize a dynamic synchronous storage mode. In practical application, the NAS disk and the substation monitoring subsystem may be connected by using a network cable, the automatic synchronization time interval is set to 3 days, when the usage exceeds a first preset percentage (e.g., 60%) in the dynamic synchronous storage mode, the data backup hard disk may display a yellow light, and when the usage exceeds a second preset percentage (e.g., 80%), the data backup hard disk automatically deletes the oldest system history data, such as the old version of the system application program, and important data, such as various alarm information and event sequence record (SOE), should be permanently stored and should not be deleted.
It should be noted that, in this embodiment, a manual storage area may also be allocated in the data backup hard disk, and when the monitoring subsystem performs operations such as version upgrade and maintenance, after an operator grants an authority, the application program and data of the monitoring subsystem may be stored in the manual storage area, and at the same time, the operator may manually delete existing stored data in the hard disk.
Optionally, after the server host calls the system backup data corresponding to the current monitoring subsystem and places the system backup data on the target virtual machine corresponding to the current monitoring subsystem for operation, the method further includes: and when a fault repaired signal sent by the current monitoring subsystem is received, the control system standby data exits from the target virtual machine.
In this embodiment, when a fault repaired signal sent by the current monitoring subsystem is received, the fault of the current monitoring subsystem may be considered to be repaired, the system standby data may be exited from the target virtual machine, that is, the operation may be stopped, and at this time, the transformer substation may be normally and effectively monitored based on the current monitoring subsystem. And when the current monitoring subsystem is recovered, the working personnel quits the target virtual machine and recovers the connection of the current monitoring subsystem.
It should be noted that, in order to ensure the accuracy of the construction of the server hosts and the corresponding virtual machines of the monitoring subsystems in the transformer substation and reduce resource waste, an effective number of server hosts may be determined based on the number of the transformer substation or the monitoring subsystems, and a corresponding number of virtual machines may be constructed on the server hosts.
Optionally, at least one monitoring subsystem to be used and the number of the corresponding subsystems are determined, wherein each monitoring subsystem to be used corresponds to one substation; determining at least one server host to be used based on the number of the subsystems, and determining at least one monitoring subsystem to be emergently corresponding to each server host to be used; and aiming at each server host to be used, creating a virtual machine to be applied of each subsystem to be monitored to be emergent corresponding to the server host to be used in the current server host to be used, so that when the current monitoring subsystem fails, the system standby data corresponding to the current monitoring subsystem is operated based on the target virtual machine corresponding to the current monitoring subsystem.
In practical applications, each substation may include a monitoring subsystem as the monitoring subsystem to be used. The number of server hosts may be determined based on the number of monitoring subsystems to be used. For example, assuming that the number of subsystems is 200, the server host may be 2, and assuming that the number of subsystems is 100, the server host may be 1. Each server host can correspond to a corresponding monitoring subsystem as a to-be-emergency monitoring subsystem. For a certain server host, a virtual machine corresponding to each subsystem to be monitored for emergency can be established in the server host, that is, each subsystem to be monitored for emergency has a virtual machine to be applied corresponding to the subsystem to be monitored for emergency. The configuration of each virtual machine can be reasonably distributed according to the operation requirements of different monitoring subsystems, and a virtual machine to be applied based on the Linux operating system and used by the corresponding monitoring subsystem is established, for example, a virtual machine of a virtualized Linux operating system can be established on a server host by adopting VirtualBox software to serve as the virtual machine to be applied. And when the current monitoring subsystem fails, running system standby data corresponding to the current monitoring subsystem based on the target virtual machine corresponding to the current monitoring subsystem.
According to the technical scheme, for the monitoring subsystems corresponding to the transformer substations, when a fault emergency request corresponding to the current monitoring subsystem is received, the server host corresponding to the current monitoring subsystem is determined; the method comprises the steps of calling system standby data corresponding to a current monitoring subsystem based on a server host, placing the system standby data on a target virtual machine corresponding to the current monitoring subsystem to run, and monitoring a corresponding transformer substation based on the running target virtual machine.
Example two
As an alternative embodiment of the above embodiment, in order to make the technical solutions of the embodiments of the present invention further clear to those skilled in the art, a specific application scenario example is given. Specifically, the following details can be referred to.
For example, referring to fig. 2, a schematic diagram of a fault emergency system may be shown. The technical scheme can be realized through the server host, the virtual machine deployed in the server host, the transformer substation network, the monitoring subsystem and the data backup hard disk. The server host machine has the capability of running a plurality of virtual machines, is used as a host machine of the virtual machines, is only provided with necessary software and hardware, and is configured with user authority management and a plurality of network cards which can be connected with a A, B network in a substation. Optionally, the server host type may be rack type, blade type, tower type, etc., and the configuration thereof satisfies that the dominant frequency is greater than 2GHz, the number of cores is greater than 8, and the ddr memory is greater than 128G. The virtual machine can be constructed through virtualization software through hardware virtualization, and an operating system of the virtual machine can be a Linux operating system and can well run a substation system application program. Alternatively, the virtualization software may employ VirtualBox, VMware, virtualPC, KVM-x86, or the like. For example, as shown in fig. 3, the number of virtual machines to be established in the server host may be determined according to the number of the substation monitoring subsystems in a certain area, for example, a virtual machine corresponding to each monitoring subsystem is created for each monitoring subsystem. The configuration of a server host can be distributed based on the operation requirement of a monitoring subsystem, for example, in order to facilitate the use of a transformer substation, the server host adopts a rack server, supports an ECC memory error correction technology and a disk array technology (RAID-5), is provided with 4 kilomega network ports, 8 PCle 4.0 high-speed channels and 16 2.5-inch hard disk positions, adopts a processor 6226 with 16 cores and a main frequency of 2.9GHz Intel to Qiangjin brand, adopts a memory of 128GB, is connected with a A, B network of the transformer substation by an optical fiber Ethernet card configured with 1000Mbps, and adopts NAT network address conversion in a network mode. And reasonably distributing the configuration of each virtual machine according to the operation requirements of different monitoring subsystems, constructing the virtual machine of a virtualized Linux operating system on a server host by adopting VirtualBox4.0 software, and correspondingly establishing the virtual machine based on the Linux operating system and used by the corresponding monitoring subsystem. Furthermore, a large-capacity data backup hard disk can be used for backing up the monitoring subsystem of the transformer substation in the district under jurisdiction and corresponding application data, and naming and distinguishing are carried out according to the station name. The data backup hard disk can be a virtual disk image document and contains corresponding configuration backup data of different transformer substation monitoring subsystems in a certain region, the format of the data backup hard disk can be VDI, and the data backup hard disk is stored in a large-capacity disk array. Specifically, for the purpose of doubling, the data backup hard disk is configured with 4 disk arrays with the same capacity of more than 8T, the capacity of each disk array is 8TB, two disk arrays respectively store the background system and corresponding system data of the substation, and the other two disk arrays are used as redundant spares. The monitoring subsystem can be installed in a transformer substation, is connected with the monitoring subsystem for communication when the monitoring subsystem is not in fault, and is used for storing application programs and system data of the monitoring subsystem. As is exemplary. Referring to fig. 4, it can be shown as a schematic diagram of a data backup hard disk, and system backup data such as a system application program and system data stored in the data backup hard disk may adopt two modes, which are a dynamic synchronous storage mode and a manual storage mode, respectively, where the dynamic synchronous storage mode is implemented as follows: the data backup hard disk is connected with the in-station monitoring subsystem in real time through a network cable, the application program and backup data of the monitoring subsystem are updated, backed up and stored by setting interval time T, when the storage capacity in the data backup hard disk exceeds 60%, the data backup hard disk can display a yellow light, and when the capacity exceeds 80%, the data backup hard disk automatically deletes the oldest system historical data. It should be noted that the oldest system history data, such as the old version of the system application, can be automatically deleted, and important data, such as various types of alarm information and sequence of events (SOE), should be permanently stored and should not be deleted. The manual storage mode is realized by the following steps: the data backup hard disk is distributed with a manual storage area, when the background system carries out operations such as version upgrading, maintenance and the like, the operator can store the system application program and the data in the area after granting the authority, and meanwhile, the operator can manually delete the stored data in the hard disk in the mode.
On the basis of the above scheme, referring to fig. 5, a schematic diagram of a fault emergency method can be shown, in practical application, whether a monitoring subsystem fails or not can be judged by monitoring faults of a substation monitoring subsystem, and when a certain substation, such as the station a monitoring subsystem, fails (including system poisoning, downtime, password locking and the like), a user can establish communication connection between a server host and a substation network and a data backup hard disk in which the monitoring subsystem is stored. And after the connection is normal, the login server host system calls system backup data such as software and backup data of the monitoring subsystem of the station A from the hard disk, and the system backup data are operated on a target virtual machine configured in a corresponding environment to realize the switching of the monitoring system. And after the fault of the monitoring subsystem in the station A is eliminated, the target virtual machine monitoring system is switched and quitted, and the operation of the monitoring subsystem in the station A is recovered. When the monitoring subsystem system of the transformer substation fails due to virus infection, computer downtime and the like, the virtual machine which is resident in the server host is utilized to call the application program of the corresponding transformer substation monitoring subsystem in the running data backup hard disk, and the application program is linked with the in-station network, so that the failed system is switched to the normal system, and the restoration of the in-station monitoring function is realized.
On the basis of the above scheme, in this embodiment, the authority in the fault emergency system may be further divided into a server administrator, a server programmer, and a server user, where the server administrator is used to manage the configuration and normal operation of the virtual machine in the server host, and manage the manual storage and deletion of data in the data backup hard disk. And the server programmer is used for managing the application programs in the server host and the virtual machine. And the server user is used for operating the virtual machine in the server host to realize the fault emergency switching function. The method is specifically realized by that three roles, namely a root system administrator, a security and confidentiality administrator and a security auditor, are arranged for managing and using the system through three rights.
In this embodiment, when a monitoring subsystem of a certain transformer substation fails, a server host is connected with an in-substation network, a virtual machine built in the server host is used for calling and operating system backup data of a system with a backup failure, and a monitoring subsystem of the transformer substation is switched from an original failure system to a virtual machine operating system of the server host.
According to the technical scheme, for the monitoring subsystems corresponding to the transformer substations, when a fault emergency request corresponding to the current monitoring subsystem is received, the server host corresponding to the current monitoring subsystem is determined; the method comprises the steps of calling system standby data corresponding to a current monitoring subsystem based on a server host, placing the system standby data on a target virtual machine corresponding to the current monitoring subsystem for operation, and monitoring a corresponding transformer substation based on the operated target virtual machine.
