Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
Example one
As shown in fig. 1, the method for optimizing scheduling tasks of a power distribution network of the present invention includes the following steps:
the dispatching server establishes communication links with the master server and the slave server;
the dispatching server receives and stores the dispatched dispatching task of the power distribution network;
the scheduling server acquires the current load conditions of the master server and the slave server;
judging whether the current load condition of the main server exceeds a preset first threshold value or not, and if not, issuing the received scheduling task of the power distribution network to the main server by the scheduling server;
if the current load condition of the main server exceeds a preset first threshold value but does not exceed a preset second threshold value, the scheduling server distributes the received scheduling tasks of the power distribution network to the main server and the slave servers according to the current load conditions of the main server and the slave servers;
if the current load condition of the master server exceeds a preset second threshold value, the scheduling server distributes the received scheduling tasks of the power distribution network to the slave servers;
specifically, the scheduling server receives a starting signal of an administrator; generating a registration instruction according to the starting signal, sending the registration instruction to the master server and the slave server, and establishing a communication link with the scheduling server after the master server and the slave server receive the registration instruction; the registration instruction comprises an IP address, and the IP address is a unique identifier of the server.
In addition, the dispatching server distributes dispatching tasks of the power distribution network to the master server and/or the slave servers in a mode of sending instructions. The instruction comprises a scheduling task of the power distribution network and an IP address of the server.
The scheduling server acquires the load conditions of the master server and the slave server in real time, wherein the load conditions comprise CPU (Central processing Unit) use, memory use and IO (input/output) consumption, the scheduling server calculates the total load condition of the current master server according to the acquired conditions of the CPU use, the memory use and the IO consumption of the master/slave servers and a pre-stored calculation formula, and the pre-stored calculation formula is as follows:
Score＝A*cpu％+B*IO％+C*men％
wherein, Score represents a load value, CPU% represents a CPU usage rate, IO% represents an IO consumption rate, and men% represents a memory usage rate, and A, B, C represents weights of the CPU usage rate, the IO consumption rate, and the memory usage rate, respectively, wherein A, B, C is added to 1, a higher weight represents a higher priority, and for example, compared with the case of the CPU usage rate, the higher CPU usage rate represents the overall load of the server, and the weighting factor a is greater than B. In this embodiment, the weighting factor is not specifically limited, and may be specifically set according to the actual situation. For example A, B, C is 0.5, 0.3 and 0.2, respectively, and may also be 0.3, 0.4 and 0.3.
Further, a server load value is obtained according to a calculation formula of the load condition of the server, generally, the performance of the master server is better than that of the slave server, in order to fully utilize the superior performance of the master server, a first threshold value is set, the load value of the master server is compared with the first threshold value, if the current load value of the master server does not exceed the preset first threshold value, the current load value represents that the master server is in a low-load condition at present, a scheduling task for processing a new power distribution network can be received, and the scheduling task issued by the scheduling center is distributed to the master server by the scheduling server. In this embodiment, the first threshold is not specifically limited, and may be set according to actual situations.
When the load value of the main server received by the scheduling server is greater than the first preset value but less than the second preset threshold value, the load value represents that the current main server is in a medium load condition, and the load value represents that the main server can receive a certain amount of scheduling tasks. In this embodiment, the value of the second preset threshold is not specifically limited, and may be set according to the actual situation, where the second preset threshold is greater than the first preset threshold.
And the dispatching server acquires the current load condition of the slave server, and if the current load condition of the slave server is smaller than a first preset value, the dispatching task of the power distribution network is distributed to the slave server.
If the load condition of the slave server at this time is not less than the first preset threshold, the scheduling server performs allocation of the scheduling task according to the load conditions of the master server and the slave server at this time and the scheduling task amount of the current power distribution network, specifically:
determining the task quantity Z of the scheduling tasks of the power distribution network, and judging whether the task quantity Z is not less than 2, if the task quantity Z of the power distribution network is less than 2, the scheduling server distributes the scheduling tasks of the power distribution network to the master server because the performance of the master server is better than that of the slave servers;
if the scheduling task amount Z of the power distribution network is not less than 2, the scheduling tasks of the power distribution network to be distributed are divided into two groups, each group at least comprises one scheduling task of the power distribution network to be distributed, and the scheduling tasks of the power distribution network are grouped according to the load states of the current master server and the slave servers.
The specific grouping of the scheduling tasks of the power distribution network is as follows:
wherein ,T1Scheduling task volume, T, of the distribution network to be received for the primary server2For the task volume of scheduling tasks of the distribution network to be received from the server, S1Is the current load value of the primary server, S2The current load value of the slave server, T is the total scheduling task amount of the power distribution network to be distributed currently, T1、T2The specific rounding rule is not particularly limited, and may be rounded, for example.
Further, when the load state of the current master server acquired by the scheduling server exceeds a preset second threshold, the scheduling task of the power distribution network is distributed to the slave servers.
In addition, when the scheduling server allocates the scheduling tasks of the power distribution network, the scheduling server generates a scheduling instruction for each scheduling task, wherein the scheduling instruction includes an IP address of the server and is sent to the corresponding server according to the IP address for processing.
The dispatch server is also configured to distribute the dispatch tasks to the distribution network when the master server and the slave servers do not fail.
When the scheduling server detects that the main server fails, all scheduling tasks of the current power distribution network are distributed to the slave servers;
when the dispatching server detects that the slave server fails, all the dispatching tasks of the current power distribution network are distributed to the master server.
When the dispatching server detects that the master server and the slave server both have faults, the dispatching server stores dispatching tasks of the power distribution network to be distributed and waits for the master server/the slave server to remove the faults.
The method also comprises the step that the master server and the slave server execute the scheduling tasks of the power distribution network distributed by the scheduling server.
