Embodiment Construction

[0035] Below in conjunction with accompanying drawing of description, the present invention will be further described.

[0036] The present invention provides a service cross-region calling method of an electric power dispatching automation system, such as figure 2 shown, including the following steps:

[0037] 1) The local proxy server determines the cross-regional remote service information that needs to be accessed in this region, and determines the port number that the cross-regional remote service that needs to be accessed is republished locally;

[0038] Wherein, the remote service information includes the scheduling institution to which the remote service belongs, the node IP address of the service provider where the remote service is located, and the port number of the remote service running on the node IP address.

[0039] 2) The local proxy server pre-establishes a TCP connection link to the remote proxy server at the opposite end according to the determined remote...

Abstract

The invention discloses a service cross-region calling method and device for a power dispatching automation system. The method comprises the following steps that (1) a local proxy server determines remote service information and a port number republished by a remote service locally; 2) the local proxy server establishes a TCP connection link with the remote proxy server at the opposite end; 3) thelocal proxy server monitors the port number to wait for an access request; 4) the local proxy server applies for a unique ID number and sends the ID number and the access request to a remote proxy server at the opposite end; 5) the remote proxy server at the opposite end sends the access request to an appointed service provider; 6) the remote proxy server of the opposite terminal returns the response result with the ID number along the TCP connection link, and 7) the local proxy server returns the response result to the service requester according to the ID number, and the remote service is re-published in the area through the proxy gateway server to realize the service remote access among different scheduling organizations.

Description

technical field [0001] The invention relates to a calling method, in particular to a method and device for cross-region calling of a power dispatching automation system in a multi-active environment, and belongs to the field of power dispatching automation. Background technique [0002] In electric power automation, in order to ensure system security, dispatching automation systems at all levels are usually not reachable by direct routing. If a node in a dispatching automation system needs to access the services of another dispatching automation system, it must pass through a local proxy gateway server. For example, for the currently widely used smart grid dispatching control system (D5000), dispatching agencies at all levels will configure two proxy gateway nodes, and these proxy gateway nodes will be reachable to each other through the dispatching data network, while dispatching agencies at all levels The internal application server can only access the local proxy gateway ...
