The invention discloses a monitoring system and method of load balance. The method is applied to a grid monitoring system including a provincial master station monitoring system, a regional master station monitoring system, an end station monitoring system, two backbone networks, a plurality of servers, a server load comparing module and a network switch, wherein the two backbone networks are used for connecting the provincial master station monitoring system and the regional master station monitoring system as well as the regional master station monitoring system and the end station monitoring system; each server is connected with the two backbone networks and used for processing monitoring information interaction and storage of the monitoring system; the server load comparing module is arranged in the servers for comparing the load conditions of the servers; and the network switch is used for connecting the two backbone networks. The invention can not only realize the load balance of the grid monitoring system and the utilization optimization of the resource transmission, but also find out the faults of the servers or network cards in time to add the link redundancy of the monitoring system, thereby ensuring the stable and reliable operation of the monitoring system to the maximum extent.
Description
Technical field
The present invention relates to realize the load-balancing technique of grid monitoring system, belong to the electrical network security protection communications field.
Background technology
Along with the continuous expansion of scale of power, the operation workload that is applied in the surveillance of electrical network increases day by day, and existing monitor data transmission means also is faced with acid test.As the expansion of Guangdong Power Grid for the reply scale of power, the grid monitoring system of take the lead in adopting provincial, local level and station end three-level structure in power industry.Stand the end supervisory control system be used to monitor transformer station's live video and environmental information, and with information uploading to the local level master supervisory system; The local level master supervisory system is used to monitor the real-time monitor message of a plurality of stations end supervisory control system, and with information uploading to provincial master supervisory system; Provincial master supervisory system is used to monitor the real-time monitor message of a plurality of local level master supervisory systems.At present, being connected of provincial master supervisory system and local level master supervisory system, local level master supervisory system generally are to connect by a backbone network with station being connected of supervisory control system of end, also are provided with some servers that transmission information between each system is handled on the backbone network.Yet, along with the increase day by day of electrical network surveillance operation workload, occurring often that the part of server load is overweight to cause transmission to be stopped up, another part server load kicks the beam and causes equipment redundancy, can't reach the optimization of the utilization of resources.
Summary of the invention
The objective of the invention is to, a kind of supervisory control system and method for load balancing are provided, the present invention not only can realize the load balancing of grid monitoring system, realize the optimization of utilizing of transfer resource, can in time find the fault of server or network interface card again, increase the link redundancy of supervisory control system, farthest guarantee stable, the reliability service of supervisory control system.
Technical scheme of the present invention: the supervisory control system of load balancing, be applied to grid monitoring system, comprise provincial master supervisory system, local level master supervisory system and station end supervisory control system, also comprise;
Article two, backbone network is used to connect provincial master supervisory system and local level master supervisory system and local level master supervisory system and station end supervisory control system;
Some servers, every station server link to each other with two backbone networks respectively, are used to handle the mutual and storage of monitor message of backbone network;
Server load comparison module is arranged in the server, in order to compare the load state of server.
The network switch is in order to connect two backbone networks.
The supervisory control system of above-mentioned load balancing, described server are provided with two network interface cards, also are provided with network interface card load comparison module.
Realize the used method of supervisory control system of aforesaid load balancing, the performance load of the real-time monitor server of server load comparison module, the server of determining the load maximum is a given server, determine that the minimum server of load is a destination server, given server is transferred to destination server with a part of Processing tasks, realizes the load balancing of electrical network video monitoring system.
In the above-mentioned method, described server is two, and be appointed as master server and from server, the performance load of the real-time monitor server of server load comparison module, be by constantly sending signal from server, then the Processing tasks of master server being transferred to from server when connecting inefficacy to master server.
In the aforesaid method, this method also is appointed as the major network card with two network interface cards and from network interface card,, then the Processing tasks of major network card is transferred to from network interface card when connecting inefficacy constantly to major network card transmission signal from network interface card, thereby has realized the equilibrium of network interface card load in the server.
Compared with prior art, the present invention is by being provided with the loaded-up condition of the real-time monitor server of server load comparison module, and the section processes task transfers of in time that load is higher server is to the lower server of load, realized the load balancing of monitor message transmission in the electrical network video monitoring system, the information processing that the present invention can avoid causing because of server load is too high is paralysed, also avoided causing equipment redundancy, reached the optimization of the utilization of resources because of server load kicks the beam.Concrete operations as load balancing, the present invention is by the equipment master server with from server, constantly send signal from server to master server, then the Processing tasks of master server is transferred to from server when connecting inefficacy, therefore the present invention can not only possess the function of server load balancing, and when master server breaks down, can in time find and take over the task of master server from server, increase supervisory control system and connected the link redundancy; The present invention has also used load-balancing technique to the network interface card in each server, farthest guarantees stable, the reliability service of supervisory control system.
