Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, a schematic diagram of a controller 100 for executing a method for preventing data loss of a power grid monitoring system based on a primary/standby channel switching technology according to an embodiment of the present application is provided.
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 other means, and fig. 1 takes the example of connection by a bus as an example.
The memory 120, which is a non-transitory computer readable storage medium, may be used to store non-transitory software programs as well as non-transitory computer executable programs. Further, the 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 optionally includes 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 embodiments of the invention and may include more or fewer components than shown, or some components may be combined, 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, so as to execute a grid monitoring system data loss prevention method based on the active/standby channel switching technology.
The method for preventing data loss of the power grid monitoring system based on the main/standby channel switching technology can be applied to the 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 connected with the first server instance and the second server instance in a communication mode.
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 data transmitted by the first remote terminal unit through the first standby channel.
The scheduling unit may include the controller.
In an embodiment, as shown in fig. 3, a method for preventing data loss of a power grid monitoring system based on a primary/standby channel switching technology is provided, which is described by taking the scheduling unit in fig. 2 as an example, and includes the following steps:
step S302, when the first server instance is detected to be abnormally hung, a first moment when the first server instance is abnormally hung is obtained.
It should be noted that, the abnormal hang-up related to the server example of the present application includes abnormal hang-up caused by an excessive load, abnormal hang-up due to virus attack, abnormal hang-up due to power failure, and the like.
In a specific implementation, when the scheduling unit detects that the first server instance is abnormally suspended, a time when the first server instance is abnormally suspended is obtained as a first time.
Step S304, the first standby channel between the first remote terminal unit and the second server instance is switched to the new first active channel, and a second time when the channel switching is successful is obtained.
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 the initial first standby channel between the first remote terminal unit and the second server instance to the 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 further needs to acquire the second time at which the channel switching is successful when the channel switching is performed, so that the subsequent second server instance searches for data before the second time at which the channel switching is successful.
Step S306, sending a control instruction to the second server instance to control the second server instance to query the data stored between the first time and the second time, and upload the data 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 search the data between the first time and the second time from the previously stored data, and upload the searched data to the background system, thereby ensuring 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 data loss of the power grid monitoring system based on the main/standby channel switching technology, when a first server instance is abnormally hung, a first moment when the first server instance is abnormally hung is obtained; and switching a first standby channel between the first remote terminal unit and the second server instance into a new first main channel, acquiring a second moment when the channel switching is successful, and finally controlling the second server instance to inquire data stored from the first moment to the second moment and upload the data to the background system.
In an embodiment, after the step of detecting the abnormal hanging of the first server instance in the step S302, the method further includes: closing a first primary channel between a first remote terminal unit and a first server instance; a third server instance is established and a new first backup tunnel is established between the first remote terminal unit and the third server instance.
Referring to fig. 4, a schematic diagram of connections between a first remote terminal unit and server instances after a first server instance is abnormally suspended, as shown in the figure, after the first server instance is abnormally suspended, in addition to closing a first main channel between the first remote terminal unit and the first server instance, a first standby channel between the first remote terminal unit and a second server instance shown in fig. 2 is switched to a new first main channel shown in fig. 3, and a third server instance is newly created, 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 primary 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 the data acquired by the first remote terminal unit is backed up to the third server instance through the first standby channel, thereby avoiding data loss when the second server instance is also abnormally suspended.
In one embodiment, if the first server instance and the second server instance are further connected with a second remote terminal unit, the second remote terminal unit is in communication connection with the second server instance through a second main channel and is in communication connection with the first server instance through a second standby channel; after the step of detecting the abnormal hanging of the first server instance in the step S302, the method further includes: the 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 schematic diagram of connections between the first remote terminal unit and the second remote terminal unit and the server instances is shown, as shown in the figure, if the first server instance and the second server instance are also connected with the second remote terminal unit, after the first server instance is abnormally suspended, the second standby channel between the second remote terminal unit and the first server instance needs to be 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 first server instance is abnormally suspended and does not affect uploading of the data acquired by the second remote terminal unit to the background system through the second server instance, the data acquired by the second remote terminal unit cannot be normally backed up to the first server instance through the second standby channel, and therefore, the scheduling unit closes the original second standby channel and establishes a new second standby channel between the second remote terminal unit and the third server instance, so that the data acquired by the second remote terminal unit is backed up to the third server instance through the new second standby channel, and the problem of data loss caused by 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 the second server instance 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.
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 start to acquire the data acquired by the first remote terminal unit in real time from the second time, so that the background system can continue to 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 acquired first time when the first server instance is abnormally suspended and the acquired second time when the channel is successfully switched to the second server instance, so that the second server instance queries the data, which is interrupted during the abnormal suspension of the first server instance, according to the first time and the second time, 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/standby channel switching technology is provided, where in this embodiment, the method includes the following steps:

step S606, close the first primary channel between the first remote terminal unit and the first server instance;
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;
step S610, sending a control instruction to the second server instance to control the second server instance to query the data stored between the first time and the second time, and upload the data to the background system, and control the second server instance to start acquiring the data acquired by the first remote terminal unit from the second time through the new first main channel, and upload the acquired data to the background system.
In the method for preventing data loss of a power grid monitoring system based on the active-standby channel switching technology provided by this embodiment, when a first server instance is abnormally suspended, a first active channel between a first remote terminal unit and the first server instance is closed, and 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 is backed up to the third server instance through the first standby channel, thereby avoiding data loss caused by the abnormal suspension of a second server instance, by switching the first standby channel between the first remote terminal unit and the second server instance to the new first active channel and acquiring a second time at which the channel switching is successful, and finally controlling the second server instance to query data stored from the first time to the second time and upload the data to a background system, and controlling the second server instance 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 the method, the data can be uploaded to the background system from the first moment when the first server instance is abnormally hung up, and accordingly data loss is avoided.
