The current instance data may refer to power consumption data, power equipment parameters, and the like, and the specific application is not limited. The current instance data uploading amount of the first server instance refers to the current data transmission amount of the first server instance.
Specifically, referring to fig. 1, a scheduling unit in the power grid monitoring system obtains a current instance data upload amount of a first server instance connected to the scheduling unit according to a preset data upload amount obtaining instruction.
It should be noted that the power grid monitoring system further includes a plurality of remote terminal units and a plurality of server instances, the plurality of server instances include a first server instance, a second server instance and a third server instance, the plurality of remote terminal units include a plurality of first remote terminal units and a plurality of second remote terminal units, each first remote terminal unit is connected to the first server instance through a first main channel and is connected to the second server instance through a first standby channel; each second remote terminal unit is connected to the second server instance through a second main channel and connected to the first server instance through a second standby channel; the scheduling units are respectively connected to a plurality of server instances. In addition, the application is not limited with respect to the number of remote terminal units and server instances; the first main channel, the first standby channel, the second main channel and the second standby channel are all data transmission channels.
Step S202, in a first time period, when the data upload amount of the current instance of the first server instance is greater than the first preset data upload amount of the first server instance, a new second standby channel is established between the second remote terminal unit and the third server instance, and then the second standby channel between the second remote terminal unit and the first server instance is closed.
The first time period refers to a preset time period, such as 10 minutes and 20 minutes, and may be adjusted according to actual needs, which is not limited in the present application. The first preset data uploading amount of the first server instance refers to a maximum data uploading amount of the first server instance.
Specifically, in a first time period, the scheduling unit monitors the data upload amount of the current instance of the first server instance in real time, and when the data upload amount of the current instance of the first server instance is greater than the first preset data upload amount of the first server instance, which indicates that the current data transmission load of the first server instance is higher, a first channel switching instruction is generated, a new second standby channel is established between the second remote terminal unit and the third server instance according to the first channel switching instruction, and then the second standby channel between the second remote terminal unit and the first server instance is closed.
Step S203, in a second time period after the first time period, when the data uploading amount of the current instance of the first server instance is smaller than the second preset data uploading amount of the first server instance, the second standby channel between the second remote terminal unit and the first server instance is restored, and then a new second standby channel between the second remote terminal unit and the third server instance is closed; the second preset data uploading amount is smaller than the first preset data uploading amount.
The second time period also refers to a preset time period, such as 10 minutes and 20 minutes, which can be adjusted according to actual needs, and the application is not limited specifically. Within a second time period after the first time period, a time period after the first time period is referred to. The second preset data uploading amount of the first server instance refers to a minimum data uploading amount of the first server instance.
It should be noted that the scheduling unit stores in advance a first preset data upload amount and a second preset data upload amount of the first server instance.
Specifically, in a second time period after the first time period, the scheduling unit monitors the data upload amount of the current instance of the first server instance in real time, and when the data upload amount of the current instance of the first server instance is smaller than a second preset data upload amount of the first server instance, which indicates that the current data transmission load of the first server instance is lower and is restored to a lower load level, a second channel switching instruction is generated, and according to the second channel switching instruction, a second standby channel between the second remote terminal unit and the first server instance is restored first, and then a new second standby channel between the second remote terminal unit and the third server instance is closed.
In the method for dynamically adjusting the pre-service channel of the power grid monitoring system based on risk prediction, in a first time period, when the data uploading amount of the current instance of the first server instance is larger than the first preset data uploading amount, that is, the current data transmission load of the first server instance is higher, the second standby channel is switched from the second remote terminal unit to the first server instance to the second remote terminal unit and the third server instance, so that the data transmission load of the first server instance in the first time period can be reduced; in addition, in a second time period after the first time period, when the data upload amount of the current instance of the first server instance is smaller than a second preset data upload amount, that is, the current data transmission load of the first server instance is lower and is restored to a lower load level, the second standby channel is switched between the second remote terminal unit and the third server instance and is restored between the second remote terminal unit and the first server instance to restore to an initial channel distribution state, so that the purpose of reasonably scheduling the data transmission channel in real time according to the load condition of the server instance is realized, and the normal transmission of data is favorably ensured.
In an embodiment, as shown in fig. 3, in the step S202, a new second standby channel is first established between the second remote terminal unit and the third server instance, and then the second standby channel between the second remote terminal unit and the first server instance is closed, which specifically includes the following steps:
step S301, a first data upload amount difference between the current instance data upload amount and the first preset data upload amount, and the current terminal data upload amount of each second remote terminal unit are obtained.
The current terminal data uploading amount of each second remote terminal unit refers to the current data transmission amount of each second remote terminal unit; the first data uploading amount difference value between the current instance data uploading amount and the first preset data uploading amount refers to an excess uploading amount of the current instance data uploading amount exceeding the first preset data uploading amount.
Specifically, the scheduling unit acquires a first data upload amount difference between the current instance data upload amount and a first preset data upload amount, and a current terminal data upload amount of each second remote terminal unit according to a preset data upload amount acquisition instruction.
Step S302, selecting a first target number of target second remote terminal units from a plurality of second remote terminal units; the sum of the current terminal data uploading amounts of the target second remote terminal units with the first target number is greater than or equal to the first data uploading amount difference.
Specifically, the scheduling unit selects a first target number of target second remote terminal units from the plurality of second remote terminal units, so that the sum of the current terminal data upload amounts of the first target number of target second remote terminal units is greater than or equal to the first data upload amount difference.
For example, the scheduling unit selects B target second remote terminal units (B is equal to or less than a) from the a second remote terminal units, so that the sum of the current terminal data upload amounts of the B target second remote terminal units is greater than or equal to the first data upload amount difference.
Step S303, a new second backup channel is respectively established between each target second remote terminal unit and the third server instance, and then the second backup channel between each target second remote terminal unit and the first server instance is closed, so that the current instance data upload amount of the first server instance is less than or equal to the first preset data upload amount.
Specifically, for each target second remote terminal unit, the scheduling unit, according to the first channel switching instruction, first establishes a new second standby channel between the target second remote terminal unit and the third server instance, and then closes the second standby channel between the target second remote terminal unit and the first server instance, so that the current instance data upload amount of the first server instance is less than or equal to the first preset data upload amount.
In the above embodiment, when the data upload amount of the current instance of the first server instance is greater than the first preset data upload amount, it is not necessary to switch the transfer of the second backup channels of all the second remote terminal units, and it is only necessary to switch the transfer of the second backup channels of a part of the second remote terminal units corresponding to the difference value of the first data upload amount, so that the operation is flexible and simple, and meanwhile, the normal transmission of data is further ensured.
In an embodiment, as shown in fig. 4, in the step S203, first restoring the second backup channel between the second remote terminal unit and the first server instance, and then closing the new second backup channel between the second remote terminal unit and the third server instance specifically includes the following steps:
step S401, a second data upload amount difference between the second preset data upload amount and the current instance data upload amount, and a current terminal data upload amount of each second remote terminal unit are obtained.
The second data upload amount difference between the second preset data upload amount and the current instance data upload amount is an idle upload amount of which the current instance data upload amount is lower than the second preset data upload amount.
Specifically, the scheduling unit acquires a second data upload amount difference between a second preset data upload amount and a current instance data upload amount, and a current terminal data upload amount of each second remote terminal unit according to a preset data upload amount acquisition instruction.
Step S402, selecting a second target number of target second remote terminal units from the plurality of second remote terminal units; and the sum of the current terminal data upload volumes of the target second remote terminal units of the second target number is less than or equal to the second data upload volume difference.
Specifically, the scheduling unit selects a second target number of target second remote terminal units from the plurality of second remote terminal units, so that the sum of the current terminal data upload amounts of the second target number of target second remote terminal units is less than or equal to the second data upload amount difference.
For example, the scheduling unit selects D target second remote terminal units (D is equal to or less than C) from the C second remote terminal units, so that the sum of the current terminal data upload amounts of the D target second remote terminal units is equal to or less than the second data upload amount difference.
Step S403, respectively, first restore the second backup channel between each target second remote terminal unit and the first server instance, and then close the new second backup channel between each target second remote terminal unit and the third server instance.
Specifically, for each target second remote terminal unit, the scheduling unit first restores the second backup path between the second remote terminal unit and the first server instance and then closes the new second backup path between the second remote terminal unit and the third server instance according to the second path switching instruction.
In the above embodiment, when the data upload amount of the current instance of the first server instance is smaller than the second preset data upload amount, it is not necessary to perform transfer switching on the second standby channels of all the second remote terminal units, and it is only necessary to perform transfer switching on a part of the second standby channels of the second remote terminal units corresponding to the difference value of the second data upload amount, so that the operation is flexible and simple, and meanwhile, normal transmission of data is further ensured.
In one embodiment, as shown in fig. 5, a schematic diagram of changes of a grid monitoring system with respect to dynamic adjustment of a channel is provided. Specifically, referring to fig. 5, in a first time period, when the data upload amount of the current instance of the first server instance is greater than the first preset data upload amount, that is, it indicates that the current data transmission load of the first server instance is higher, for this reason, the present application switches the second backup channel from between the second remote terminal unit and the first server instance to between the second remote terminal unit and the third server instance, so that the data transmission load of the first server instance in the first time period can be reduced; in addition, in a second time period after the first time period, when the data uploading amount of the current instance of the first server instance is smaller than a second preset data uploading amount, namely the current data transmission load of the first server instance is low and is restored to a low load level, the second standby channel is switched between the second remote terminal unit and the third server instance and is restored between the second remote terminal unit and the first server instance so as to be restored to the initial channel distribution state; therefore, the data transmission channel can be reasonably scheduled in real time according to the load condition of the server instance so as to ensure normal transmission of data.
It should be noted that, regarding the first main channel and the first standby channel, when the power grid monitoring system is in a normal condition, the power grid monitoring system may utilize and analyze data transmitted through the first main channel, and may not utilize and analyze data transmitted through the first standby channel; similarly, regarding the second main channel and the second standby channel, when the power grid monitoring system is in a normal condition, the power grid monitoring system may utilize and analyze the data transmitted through the second main channel, and may not utilize and analyze the data transmitted through the second standby channel.
