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.

Those skilled in the art will appreciate that the controller 100 shown in fig. 1 is not meant to limit embodiments of the present application and may include more or fewer components than those 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 channel allocation program stored in the memory 120, so as to execute a grid monitoring system channel allocation method based on server instance capacity reduction.
In one embodiment, as shown in fig. 2, fig. 2 is an architecture diagram of a power grid monitoring system provided by an embodiment of the present application. The power grid monitoring system of the embodiment of the application includes, but is not limited to, a server instance 210, a remote terminal unit 220, and a scheduling unit 230, where the server instance includes more than three instances, and the scheduling unit may include the above-mentioned controller.
Specifically, the server instance 210 of the embodiment of the present application includes a first server instance 211, a second server instance 212, and a third server instance 213; remote terminal unit 220 comprises a first remote terminal unit 221, the first remote terminal unit 221 being connected to the first server instance 211 via a first primary channel, the first remote terminal unit 221 being further connected to the second server instance 212 via a first backup channel; the scheduling unit 230 is connected to each server instance, respectively.
In this embodiment, a method for allocating channels of a power grid monitoring system based on server instance capacity reduction is provided, and for example, the method is applied to a scheduling unit in fig. 2, as shown in fig. 3, the method includes steps S100 to S300.
Step S100, a capacity reduction notification message for indicating that the first server instance is about to be closed is obtained.
A server instance is an abstraction of a server, and multiple instances can be installed on one server, and multiple libraries can be installed under one instance. Wherein, the capacity reduction notification message is used for representing that the server instance is about to be closed; in one embodiment, the abbreviated notification message may be input by a user, and when the user decides to turn off the first server, the abbreviated notification message is sent out, and the scheduling unit receives the abbreviated notification message and adaptively adjusts the connection relationship between the server instance and the remote terminal unit according to the abbreviated notification message. In another embodiment, the short-cut notification message may also be automatically sent by the server instance, for example, when the server instance has a condition that cannot continue to run, the server instance automatically sends the short-cut notification message to the scheduling unit. In other embodiments, the abbreviated notification message may be obtained by any other method.
Step S200, the first standby channel between the first remote terminal unit and the second server instance is switched to a new first active channel according to the capacity reduction notification message.
Step S300 is to close the first active channel between the first remote terminal unit and the first server instance, and establish a new first standby channel between the first remote terminal unit and the third server instance.
As the first server is to be closed, the first remote terminal unit connected to the first server through the main channel needs to be replaced with a new main channel, and as can be seen from the architecture diagram of the power grid monitoring system shown in fig. 2, the first remote terminal unit is connected to the second server instance through the first standby channel, so that when the first server instance is to be closed, the first standby channel between the first remote terminal unit and the second server instance is first switched to the new first main channel, and the original first main channel is closed. In addition, a new channel is established between the first remote terminal unit and the third server instance as a backup channel for the first remote terminal unit, i.e. a new first backup channel. Fig. 4 is a diagram illustrating a power grid monitoring system architecture after updating a connection channel of a first remote terminal unit in one embodiment.
According to the power grid monitoring system channel allocation method based on server instance capacity reduction, after a first server instance in a power grid monitoring system needs to be closed, a scheduling unit can switch a first standby channel between a first remote terminal unit of the first server instance and a second server instance into a new first main channel, meanwhile, the scheduling unit can close the first main channel between the first remote terminal unit and the first server instance, and a new first standby channel is established between the first remote terminal unit and a third server instance. The method can switch the associated first standby channel to the new first main channel in time, then close the affected first main channel, and establish the new first standby channel, can realize automatic and reasonable scheduling of the data transmission channel under the condition that the server instance needs to be closed, and has intelligent and simple operation.
Fig. 5 is an architecture diagram of a power grid monitoring system according to another embodiment. In this embodiment, the remote terminal unit 220 in the digital grid pre-dispatching unit further includes a second remote terminal unit 222, and the second remote terminal unit 222 is connected to the second server instance 212 through a second main channel and connected to the first server instance 211 through a second standby channel.
Further, in this embodiment, as shown in fig. 6, the method further includes step S400: the second backup path between the second remote terminal unit and the first server instance is closed based on the capacity reduction notification message and a new second backup path is established between the second remote terminal unit and the third server instance.
When receiving a capacity reduction notification message indicating that the first server instance is to be closed, since the second remote terminal unit is connected to the first server instance through the second backup tunnel, in this embodiment, the scheduling unit further needs to establish a new backup tunnel, that is, a new second backup tunnel, between the second remote terminal unit and the third server instance, and simultaneously close the original second backup tunnel between the second remote terminal unit and the first server instance. Furthermore, the second active channel of the second remote terminal unit does not need to be switched, since the second server instance connected to the second remote terminal unit via the second active channel is not affected.
Fig. 7 is an architecture diagram of the grid monitoring system after updating the second backup tunnel of the second remote terminal unit, in one embodiment.
Fig. 8 is an architecture diagram of a power grid monitoring system according to another embodiment. In this embodiment, the remote terminal unit 220 in the power grid monitoring system further includes a third remote terminal unit 223, and the third remote terminal unit 223 is connected to the third server instance 213 through a third main channel and is connected to the first server instance 211 through a third standby channel.
In this embodiment, with reference to fig. 6, the method further includes step S500: the third backup path between the third remote terminal unit and the first server instance is closed based on the scale notification message and a new third backup path is established between the third remote terminal unit and the second server instance.
When receiving the capacity reduction notification message indicating that the first server instance is to be closed, since the third remote terminal unit is connected to the first server instance through the third backup channel, in this embodiment, the scheduling unit further needs to establish a new backup channel, that is, a new third backup channel, between the third remote terminal unit and the second server instance, and simultaneously close the original third backup channel between the third remote terminal unit and the first server instance. Furthermore, the third active channel of the third remote terminal unit does not need to be switched, since the third server instance connected to the third remote terminal unit via the third active channel is not affected.
Fig. 9 is an architecture diagram of the grid monitoring system after updating the third backup tunnel of the third remote terminal unit, in one embodiment.
In the foregoing embodiment, when receiving a capacity reduction notification message, first determining a target server instance to be closed according to the capacity reduction notification message, if there is a first target remote terminal unit connected to the target server instance through a primary channel, switching a standby channel corresponding to the first remote terminal unit to a new primary channel, closing the original primary channel, searching for a new server instance in a scheduling system, and establishing a new standby channel between the new server instance and the first target remote terminal unit. Further, if there is a second target remote terminal unit connected to the target server instance through a backup path, another server instance is searched in the scheduling system, and a new backup path is established between the server instance and the second target remote terminal unit.
Further, in an embodiment, when a new server instance is searched in the scheduling system and a new standby channel is established, the selected new server instance may be determined according to resource usage of each server instance and connection with the remote terminal. For example, the resource utilization rates of all available server instances (server instances connected by non-main channels) are ranked, the server instance with the lower resource utilization rate is selected as the selected server instance, and a new standby channel is established between the remote terminal unit and the selected server instance. For another example, the remaining resources of all available server instances (server instances not connected by the primary channel) are sorted, and a server instance with a larger remaining resource is selected as the selected server instance. For another example, the number of terminal connections of all available server instances (server instances connected by non-main channels) is sorted, and the server instance with the least number of terminal connections is selected as the selected server instance. Where resource usage may represent computing resource usage, and the like.
In this embodiment, a new standby channel is established by selecting a server instance according to the resource usage and the connection with the remote terminal unit, and a better server instance can be screened to ensure the service condition of the remote terminal unit.
In another embodiment, when a new server instance is searched in the scheduling system and a new backup channel is established, a user instruction may also be received, a new server instance to be selected is determined according to the user instruction, and the new backup channel is established between the new server instance and the remote terminal unit.
Further, in an embodiment, the scheduling unit switches the standby channel to a new active channel, establishes a new standby channel, and closes the original active channel and standby channel, which may be implemented in any manner.
Further, in an embodiment, the capacity reduction notification message carries closing time information used for characterizing the first server instance; in this embodiment, switching the first standby channel between the first remote terminal unit and the second server instance to the new first active channel includes: the first backup path between the first remote terminal unit and the second server instance is switched to a new first active path before the time information is turned off.
The closing time information represents time information carried in the abbreviated notification message, and the time information is used for representing the accurate closed time of the first server instance, so that the first standby channel between the first remote terminal unit and the second server instance must be switched to the new first main channel before the time. In one embodiment, the closing time information may be user-defined or automatically determined by the server instance; it will be appreciated that the closing time information must be after the current time.
In a specific embodiment, as shown in fig. 10, fig. 10 is a schematic diagram of a change of the power grid monitoring system provided in this embodiment before channel allocation and before channel allocation. Specifically, after a first server instance in the server instance needs to be closed, the scheduling unit may switch a first standby channel between the first remote terminal unit and the second server instance to a new first active channel, and at the same time, the scheduling unit may close the first active channel between the first remote terminal unit and the first server instance, and establish a new first standby channel between the first remote terminal unit and the third server instance. According to the technical scheme of the embodiment of the application, the embodiment of the application can timely switch the associated first standby channel into the new first main channel, then close the affected first main channel, and establish the new first standby channel, so that the embodiment of the application can realize automatic and reasonable scheduling of the data transmission channel under the condition that the server instance needs to be closed, and the operation is intelligent and simple.
It should be noted that, the above examples of the server need to be shut down, which includes situations that the load is too high, which results in shutdown, shutdown due to virus attack, shutdown due to power failure, and so on.
It should be noted that, regarding the first active channel and the first standby channel, when the system is normal, the system will utilize and analyze the data transmitted through the first active channel, but will not utilize and analyze the data transmitted through the first standby channel. When the first main channel has a problem, the first standby channel is switched to a new first main channel.
According to an embodiment of the present application, as shown in fig. 11, fig. 11 is a schematic diagram of a change of a power grid monitoring system provided in another embodiment of the present application before channel allocation and before channel allocation. Specifically, when there is a second remote terminal unit connected to the second server instance through the second main channel and connected to the first server instance through the second standby channel, after the first server instance needs to be shut down, the scheduling unit may maintain the second main channel between the second remote terminal unit and the second server instance, and at the same time, the scheduling unit may also shut down the second standby channel between the second remote terminal unit and the first server instance and establish a new second standby channel between the second remote terminal unit and the second server instance. According to the technical scheme of the embodiment of the application, the second standby channel of the second remote terminal unit can be scheduled in time, and the situation that data cannot be transmitted after the first server instance and the third server instance need to be closed at the same time is prevented. Therefore, the embodiment of the application can realize automatic and reasonable scheduling of the data transmission channel under the condition that the server instance needs to be closed, and is intelligent and simple to operate.
According to the embodiment of the application, the channel allocation can be realized before the first server instance is closed according to the closing time information, the channel allocation can be performed in advance, and the stability is high.
