Description

A Realization Method of Integrated Power Information Bus Parameter Synchronization

technical field

The invention belongs to the technical field of power systems, and in particular relates to a method for realizing parameter synchronization of an integrated power information bus.

Background technique

Each software application system in the power system must be deployed in two safety partitions, the production area and the management area, in accordance with the requirements of safety regulations, and they must be isolated by physical devices. There are data exchange requirements in the same region and across regions among software application systems. The data exchange bus implemented with SOA architecture can well meet the data exchange requirements, but it can only be deployed in one safe area. At the same time, the high reliability requirements of the power software system make the actual project adopt a dual-bus server configuration scheme, so The power information data exchange bus must be a virtual integrated bus composed of four buses deployed on four bus servers across security partitions. The effective synchronization of the configuration parameters of the four bus server buses has become a problem that must be solved.

The current configuration parameter synchronization technology generally uses the database as the synchronization source. When the parameters are updated, they are directly updated to the database, and then the bus servers of each node are notified to read new parameters from the database uniformly. This technology is based on the high reliability of the database. However, the power information interaction bus does not configure database software and hardware, so the parameter configuration of the information bus cannot adopt this general technology.

There is also a database in a system connected to the information bus as a synchronization source, and the above technology is used to realize parameter synchronization. However, the independence of information bus deployment is reduced, and the degree of coupling between bus deployment and other systems is artificially increased, which is obviously not an optimal solution for information bus system implementation.

Contents of the invention

In order to solve the technical problem of effectively synchronizing the configuration parameters of the power information data exchange bus existing in the prior art, the present invention proposes a method for realizing parameter synchronization of the integrated power information bus. The invention designs a cross-area synchronization module, a network synchronization module, a parameter update module, and a local synchronization module, and cooperates with the setting of each bus server directory to realize the parameter synchronization of the multi-bus servers of the integrated power information bus and ensure the reliable and effective operation of the bus.

The technical feature names used in this application are defined and described below.

(2) When the configuration of a certain bus server changes, the parameter update program of this bus server modifies the content of parameters in the cross-region synchronization source directory and network synchronization source directory of the server machine. As shown in Figure 4, the cross-region synchronization source directory and the network synchronization source directory of the machine have changed from a gray-bottomed box to a white-bottomed box, indicating that the parameter content of these two directories has changed, and the parameter modification content needs to be synchronized to other buses on the server.

(3) The cross-region synchronization module on each bus server monitors the cross-region synchronization source directory of the server. After finding the update, the configuration content in it is responsible for updating the network synchronization source directory of any bus server in the other security zone. , delete the content that has been successfully updated in the local cross-region synchronization source directory. As shown in Figure 5, the network synchronization source directory of a bus server in the security zone on the other side has changed from a gray-bottomed box to a white-bottomed box, indicating that the content of parameters in this directory has changed and subsequent synchronization operations are required. The network synchronization source directory of , changes from a white-bottomed box to a gray-bottomed box, indicating that this directory is in its initial state and no synchronization operation is required.

(4) The network synchronization module on each bus server monitors the network synchronization source directory of the server. After updating, the configuration content in it is responsible for updating the local synchronization source directory (ESB_local_source) of another bus host on the same side, and the local synchronization source directory (ESB_local_source) on the server. After the local synchronization source directory is successful, delete the contents of the server network synchronization source directory that have been successfully updated. As shown in Figure 6, the local synchronization source directory of each bus server has changed from a gray-bottomed box to a white-bottomed box, indicating that the parameter content of these directories has changed, while the network synchronization source directory of each bus server is a gray-bottomed box , indicating that these directories are in an initial state and no synchronization is required

(5) The local synchronization module on each bus server monitors the local synchronization source directory of this server. After updating, it sends a local message to notify the local program that needs to change the configuration, and completes the synchronization of configuration information. When this item on all bus servers After the tasks are all completed, the directory set on each bus server returns to the initial state that does not need to be synchronized. As shown in Fig. 3, it is the initial state, each directory has not been updated, and no synchronization is required.
