Problems solved by technology

The collected data distribution technology is located in the application layer, there is a large amount of redundant data transmission, and the utilization rate of network resources is not high
Moreover, the existing intelligent substation information communication architecture is based on the traditional TCP / IP architecture, which has certain defects in flexibility, fault tolerance, and high efficiency. The competition between the internal protocols of the network makes the IP layer seriously hinder the network Increased performance hinders the development of new applications such as grid mobile access points, distributed information processing, and streaming media

Embodiment 1

[0040]Embodiment 1 of the present invention: an intelligent substation communication method based on an information center network, such as figure 1 shown, including the following steps:

[0041] S1, client A sends a data access packet to upstream router A, where the packet header of the data access packet includes a data access request and a unique routing identifier, where the unique routing identifier is an information name including an authorization attribute.

[0042] Wherein, the authorization attribute includes authorization, delegation authorization and unauthorized; for data with high security level, the authorization attribute of its unique routing identifier is authorization; for data with general security level and reaching a threshold value, the authorization attribute of its unique routing identifier is Delegated authorization; for data with a low security level, the authorization attribute of its unique routing identifier is unauthorized.

[0043] The security ...

Embodiment 2

[0047] Embodiment 2 of the present invention: an intelligent substation communication method based on an information center network, such as figure 2 shown, including the following steps:

[0048] S1, client B sends the access message of the result data described in Embodiment 1 to its upstream router B;

[0049] S2, check whether the upstream router B has forwarded the result data, and if it has forwarded it, check whether the upstream router B stores the result data, and if so, directly forward the result data to the client B by the upstream router B, If not, check whether other routers on the forwarding path store the result data according to the distance from near to far, obtain the result data from the nearest router, and forward it to client B; if it has not been forwarded, then Go to step S3;

[0050] S3: Detect whether the upstream router of the upstream router B has forwarded the result data, and repeat step S2 until a router that stores the result data is found. ...

Embodiment 3

[0051] Embodiment 3 of the present invention: an intelligent substation communication method based on an information center network, such as image 3 shown, including the following steps:

[0052] S1, client A sends a data access packet to upstream router A, where the packet header of the data access packet includes a data access request and a unique routing identifier, where the unique routing identifier is information including authorization attributes and forwarding attributes name.

[0053] Wherein, the authorization attribute also includes authorization, delegation authorization and unauthorized; for data with high security level, the authorization attribute of its unique routing identifier is authorization; for data with general security level and reaching a threshold, its unique routing identifier authorization attribute It is delegated authorization; for data with a low security level, the authorization attribute of its unique routing identifier is unauthorized.

Abstract

The invention discloses an intelligent substation communication method and system based on an information center network. The method includes the steps that firstly, a client side A sends a data access message to an uplink router A, a message header comprises a data access request and a unique route distinguisher, and the unique route distinguisher is the information name comprising authorization attributes; secondly, the uplink router A forwards the data access message to a transformer substation data source end, the data source end returns a result message to a router in a transformer substation data transmission network, and a message header of the result message includes the responsive data access request, result data and the unique route distinguisher, wherein the result data and the unique route distinguisher are provided for the client side A; thirdly, the authorization attributes of the unique route distinguisher are detected, if the authorization attributes are authorization or delegation authorization, the router has the cache function, and the router is then used for storing the result data and forwards the result data to the client side A. According to the intelligent substation communication method and system based on the information center network, redundant data can be reduced, and the network resource utilization rate and the power data transmission efficiency are improved.
