It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
Referring to fig. 1, a schematic diagram of a controller 100 for performing a method for preventing data loss of a grid monitoring system based on a primary-backup channel switching technology is provided in an embodiment of the present application.
In the example of fig. 1, the controller 100 is provided with a processor 110 and a memory 120, wherein the processor 110 and the memory 120 may be connected by a bus or otherwise, in fig. 1 by way of example.
Memory 120, as a non-transitory computer-readable storage medium, may be used to store non-transitory software programs as well as non-transitory computer-executable programs. In addition, memory 120 may include high-speed random access memory, and may also include non-transitory memory, such as at least one magnetic disk storage device, flash memory device, or other non-transitory solid state storage device. In some embodiments, memory 120 may optionally include memory located remotely from processor 110, which may be connected to the controller via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.
It will be appreciated by those skilled in the art that the controller 100 shown in fig. 1 is not limiting of the embodiments of the invention and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.
In the controller shown in fig. 1, the processor 110 may call a data loss prevention program stored in the memory 120, thereby performing a grid monitoring system data loss prevention method based on a primary-backup channel switching technology.
The method for preventing the data loss of the power grid monitoring system based on the main and standby channel switching technology can be applied to an application environment shown in fig. 2. The first remote terminal unit is in communication connection with the first server instance through a first main channel and is in communication connection with the second server instance through a first standby channel; the scheduling unit is respectively in communication connection with the first server instance and the second server instance.
Wherein the first remote terminal unit is used for collecting data.
The first server instance is used for receiving data transmitted by the first remote terminal unit through the first main channel and uploading the data to the background system in real time.
The second server instance is used for backing up the data transmitted by the first remote terminal unit through the first standby channel.
The scheduling unit may include the controller.
In one embodiment, as shown in fig. 3, a method for preventing data loss of a power grid monitoring system based on a primary-backup channel switching technology is provided, and the method is applied to the scheduling unit in fig. 2 for illustration, and includes the following steps:
in step S302, when abnormal hanging of the first server instance is detected, a first moment of abnormal hanging of the first server instance is obtained.
It should be noted that, the abnormal hanging of the server example of the present application includes the situations of abnormal hanging caused by too high load, abnormal hanging under virus attack, abnormal hanging under power-off, and the like.
In a specific implementation, when the scheduling unit detects that the first server instance is abnormally hung up, the moment of the first server instance, which is abnormally hung up, is obtained as the first moment.
Step S304, switching the first standby channel between the first remote terminal unit and the second server instance to a new first main channel, and obtaining a second moment of successful channel switching.
In a specific implementation, when the first server instance is abnormally suspended, in order to ensure that the data acquired by the first remote terminal unit can still be uploaded to the background system in real time, the scheduling unit switches an initial first standby channel between the first remote terminal unit and the second server instance to a new first main channel, so that the second server instance can acquire the data acquired by the first remote terminal unit through the new first main channel, and in addition, when the channel switching is performed, a second moment of successful channel switching needs to be acquired, so that the subsequent second server instance searches the data before the second moment of successful channel switching.
Step S306, a control instruction is sent to the second server instance to control the second server instance to inquire the data stored between the first time and the second time, and the data is uploaded to the background system.
In a specific implementation, since the second server instance backs up the data transmitted by the first remote terminal unit through the first standby channel, after receiving the control instruction sent by the scheduling unit, the second server instance can find out the data between the first moment and the second moment from the data stored before and upload the found data to the background system, so that the background system can still obtain the data after the first server instance is abnormally hung even if the first server instance is abnormally hung.
In the method for preventing the data loss of the power grid monitoring system based on the main and standby channel switching technology, when a first server instance is abnormally hung, a first moment of the first server instance being abnormally hung is acquired; the method comprises the steps of switching a first standby channel between a first remote terminal unit and a second server instance into a new first main channel, acquiring a second moment when the channel is successfully switched, and finally controlling the second server instance to inquire data stored from the first moment to the second moment and uploading the data to a background system.
In one embodiment, after the step of detecting that the first server instance is abnormally suspended in step S302, the method further includes: closing a first main channel between a first remote terminal unit and a first server instance; a third server instance is established and a new first alternate path is established between the first remote terminal unit and the third server instance.
Referring to fig. 4, a schematic diagram of a connection between a first remote terminal unit and each server instance after the first server instance is abnormally suspended, as shown in the drawing, after the first server instance is abnormally suspended, a first standby channel between the first remote terminal unit and the second server instance shown in fig. 2 is switched to a new first standby channel shown in fig. 3 in addition to a first main channel between the first remote terminal unit and the first server instance, and a third server instance is newly established, and a new first standby channel is established between the first remote terminal unit and the third server instance.
In this embodiment, after the first server instance is abnormally suspended, the scheduling unit closes the first main channel between the first remote terminal unit and the first server instance, and then establishes a new first standby channel between the first remote terminal unit and the third server instance, so that data acquired by the first remote terminal unit is backed up to the third server instance through the first standby channel, and data loss caused when the second server instance is abnormally suspended is avoided.
In one embodiment, if the first server instance and the second server instance are further connected to a second remote terminal unit, the second remote terminal unit is communicatively connected to the second server instance through a second primary channel and is communicatively connected to the first server instance through a second backup channel; after the step of detecting that the first server instance is abnormally suspended in step S302, the method further includes: a second backup path between the second remote terminal unit and the first server instance is closed and a new second backup path is established between the second remote terminal unit and the third server instance.
Referring to fig. 5, after the first server instance is abnormally suspended, a connection diagram between the first remote terminal unit and the second remote terminal unit and each server instance is shown, if the first server instance and the second server instance are further connected with the second remote terminal unit, as shown in the drawing, after the first server instance is abnormally suspended, a second standby channel between the second remote terminal unit and the first server instance is further closed, and a new second standby channel is established between the second remote terminal unit and the third server instance.
In this embodiment, although the abnormal suspension of the first server instance does not affect the uploading of the data collected by the second remote terminal unit to the background system through the second server instance, the data collected by the second remote terminal unit cannot be normally backed up to the first server instance through the second standby channel, so the scheduling unit establishes a new second standby channel between the second remote terminal unit and the third server instance by closing the original second standby channel, so that the data collected by the second remote terminal unit is backed up to the third server instance through the new second standby channel, and the problem that the data is lost due to the abnormal suspension of the second server instance during the abnormal suspension of the first server instance is avoided.
In one embodiment, after the step S304, the method further includes: and controlling a second server instance to acquire data acquired by the first remote terminal unit from a second moment through the new first main channel, and uploading the acquired data to a background system.
In this embodiment, after the first standby channel between the first remote terminal unit and the second server instance is successfully switched to the new first main channel, the second server instance is controlled to acquire the data acquired by the first remote terminal unit in real time from the second moment, so that the background system can continuously acquire the data acquired by the first terminal unit after the first server instance is abnormally suspended.
In one embodiment, before the step S306, the method further includes: and transmitting the acquired first time and second time to a second server instance.
In this embodiment, the scheduling unit sends the obtained first moment when the first server instance is abnormally suspended and the obtained second moment when the channel is successfully switched to the second server instance, so that the second server instance queries data which are transmitted in an interrupt period during the abnormal suspension of the first server instance according to the first moment and the second moment, and sends the data to the background system.
In another embodiment, as shown in fig. 6, a method for preventing data loss of a power grid monitoring system based on a primary-backup channel switching technology is provided, and in this embodiment, the method includes the following steps:

step S608, establishing a third server instance, and establishing a new first standby channel between the first remote terminal unit and the third server instance;

According to the power grid monitoring system data loss prevention method based on the main and standby channel switching technology, when a first server instance is abnormally hung and dead, a first main channel between a first remote terminal unit and the first server instance is closed, a new first standby channel is established between the first remote terminal unit and a third server instance, so that data acquired by the first remote terminal unit are backed up to the third server instance through the first standby channel, data loss caused when the second server instance is abnormally hung and dead is avoided, the first standby channel between the first remote terminal unit and the second server instance is switched to the new first main channel, a second moment when the channel switching is successful is acquired, finally the second server instance is controlled to inquire data stored from the first moment to the second moment and upload the data to a background system, and the second server instance is controlled to acquire the data acquired by the first remote terminal unit from the second moment through the new first main channel and upload the acquired data to the background system. By adopting the method, the data after the first moment of abnormal suspension of the first server instance can be uploaded to the background system, so that the data loss is avoided.
