Description

Application system information synchronization method and system based on distribution network master station bus
Technical Field
The invention relates to the technical field of intelligent power distribution and utilization information, in particular to an application system information synchronization method based on a distribution network master station bus.
Background
Because each subsystem among the power systems has no uniform data standard, and each subsystem is developed by different outsourcers, the used hardware equipment, the operating system, the database system and the database table have different numbers and types of fields. Therefore, power enterprises are easy to form a mesh structure which is difficult to manage and maintain, and finally, the data synchronization is complicated. Through the information interaction bus, each subsystem between the power systems can perform data transmission, information synchronization and integration and conversion of heterogeneous data. Due to the need to standardize customer information in the information industry, the data synchronization between subsystems in the past has the following disadvantages:
(1) when the attribute data types of the table fields in the heterogeneous database are inconsistent, data synchronization cannot be completed when a plurality of subsystems exchange data with each other;
(2) in the point-to-point exchange mode, if one system at two ends of the exchange data runs abnormally, or data synchronization cannot be completed due to network congestion, data inconsistency at two ends of an application system can be caused;
(3) the problem caused by the point-to-point exchange mode is that data synchronization between systems is easy to form a mesh mechanism, which is not beneficial to later system maintenance and system expansion.
Currently, the main data synchronization schemes are as follows:
(1) document transmission
Document transmission is generally used in scenarios such as sensitive data backup, basic data required for product online, and the like. Such as business data of transactions conducted by bank customers and basic configuration parameters of products on-line. The scheme is suitable for a manual operation mode, and has the characteristics of simple implementation steps, common use and the like. Meanwhile, the method has the defects of poor real-time performance, insufficient flexibility and the like.
(2) Data replication techniques
The data copying technology is to copy the same data source to different servers, so that different users can share the data within the permission range. The data replication technology can ensure that data of different nodes are automatically updated, so that the consistency of the data is ensured. The data replication technology improves the usability of the distributed database, but has the defects that: synchronous updating among heterogeneous distributed databases is not supported; ② synchronous updating among different table structures is not supported.
(3) WebService technology
At present, the scheme is used more in projects, and the use scene is mainly used for unidirectional data synchronization. The principle is that the WebService server externally issues a common interface program (data source), and a destination terminal needing to synchronize the data source calls a server terminal interface program to obtain data to complete a data synchronization process. Under the current IDE environment, the scheme is simple to realize, has high development speed, and has the characteristics of cross-language calling and the like. However, WebService has a limited data transmission amount, and therefore, transmission of data is prone to timeout, and the like.
(4) Soeket + JDBC technology
Socket is a module for providing a network communication function, and JDBC (Java databank Connection) is an interface program for accessing a DataBase standard. The combination scheme is used in some special environments. For example, all account information of the Oracle database on the Unix host needs to be returned through the network, the database account information is obtained through JDBC first, and then the account information is returned through the Socket mode. Compared with WebServie, the scheme improves the data transmission amount, but has the defects of high difficulty, high cost and the like in Socket development due to various uncertain factors of the network.

Each business application system can extract metadata required by an enterprise, generate a uniform metadata model according to metadata specifications after data cleaning and conversion, and load the data into a local database in an XML (extensive makeup language) message format. The electric power GIS platform can centralize the metadata model of each business application system, and realize the conversion from the metadata to the distribution network data at the platform end.

analyzing the obtained XML message to obtain metadata of the application system information to be synchronized, wherein the metadata comprises the following steps: and analyzing the XML message to obtain an XML message, and converting the XML message to obtain metadata of the information of the application system to be synchronized.
The specific implementation principle of the JMS service is shown in fig. 4, and mainly relates to the following:
(1) data source
In this example, the data source refers to a database of each business application system, such as Oracle, SQLServer, Mysql, Sybase, DB2, and other database application systems.
(2) A data access resolution component: and providing the functions of reading data, packaging the data into XML messages, analyzing the XML messages and storing the XML messages in a storage. The module has the main functions of:
establishing mapping between database metadata and XML messages according to data updating request information submitted by an upper layer (other application systems and the like), and converting the updated database metadata into XML messages;
and analyzing and warehousing according to the XML message retrieved from the JMS service component.
(3) XML message service component
The assembly has five main functions:
packaging the XML data message transmitted by the data access analysis component into an XML message (packaging the XML message data into a JMS message refers to the message as the XML message).
Establishing connection with the JMS service assembly;
thirdly, sending the XML message to a corresponding message queue or theme on the JMS server;
receiving the message from the JMS server;
fifthly, the XML message is analyzed into an XML message and is transmitted to a data access analysis component of a lower layer.
(4) JMS service assembly
The component is an intermediary of the system and the system for message synchronization, and the message synchronization of the two subsystems can be smoothly carried out due to the asynchronism, the persistence and the reliability of the message transmission by the component. In practical application, an application interface carrying a JMS service component often cannot meet the requirement of message passing performance, and at this time, a solution of a JMS cluster component may be adopted to solve the problem.
The data source, the data access analysis component and the XML message service component can be realized in a business application system.
When in application, the process of implementing data synchronization between multiple service application systems may be: firstly, a data access analysis module reads data from a system A and assembles the data into an XML message, and the XML message is sent to a theme (Topic) or a message Queue (Queue) on a JMS service component through an XML message service component; secondly, the XML message service component of the system B end monitors a corresponding queue on the JMS service component or a Topic (Topic) on a subscription (Sub) JMS service component, once the message exists, the XML message service component transmits the message to a data access analysis component of the system B end, and then the message is analyzed and put in storage. And finally completing one data synchronization operation. If there are power service system a and power service system B, at this time, database data in system B is changed, and it is necessary to synchronize data to system a.
To illustrate the data synchronization between systems A, B, the process includes:
(1) system B synchronizes data to the JMS service component, the flow is as in fig. 5, including:
firstly, the database of the service system B is changed, and a database information interaction bus is triggered to call a data access analysis component to format the changed data into an XML message;
the XML message service component encapsulates the XML message uploaded by the data access analysis component into XML message, connects the JMS service component and sends the XML message to a queue on the JMS service component;
before sending XML message, need to judge whether to connect JMS service assembly, if connect, send XML message through sending XML message module directly, otherwise, need to carry on JMS service assembly connection, judge whether to connect again, if it is unable to connect to exceed three times, finish directly.
(2) System a accepts data from the JMS service component, as in fig. 6, including:
firstly, an XML message service component of a business system A monitors a queue or a theme on a JMS service component, and when a message arrives, the XML message service component receives the message and transmits an XML message to a lower-layer data access analysis component;
receiving the XML message by the data access analysis component, analyzing the XML message, and performing warehousing operation;
and thirdly, the system monitors the monitoring queue or the theme at regular time.
The data synchronization core processing flow is as shown in fig. 7, that is, encapsulating the XML message data into the JMS message includes:
1) judging whether the XML message needs to be processed by the information exchange platform according to the metadata specification, if so, turning to the step 2), otherwise, judging whether special processing and information integration are needed according to the metadata specification, if so, directly outputting the XML message after corresponding processing, and directly outputting the XML message without directly outputting the XML message;
2) judging whether standard data model association is carried out with the information exchange platform, if so, directly switching to an output module, otherwise, switching to the step 3);
3) judging whether the incoming XML message needs model conversion, if not, updating the standard data model, and directly switching to an output module, otherwise, switching to the step 4) to perform model conversion;
4) and converting the XML message structure into a standard structure of the bus platform, performing attribute conversion and data dictionary conversion on the upstream system and the bus platform, and updating a standard data model. Turning to the step 5);
5) judging whether the message needs to be subjected to model conversion with a downstream system, if so, turning to the step 6), otherwise, directly outputting the message to the downstream system;
6) and the bus platform and the downstream system perform attribute conversion, and the converted XML message is output to the downstream system after the conversion is finished.
The above-mentioned case requiring special treatment may be: if the identifiers are not matched, the information is returned and error information is sent out; the above-mentioned situations requiring information integration may be: the upper layer data source is too large, the metadata is segmented and encapsulated into a plurality of XML messages, and integration is needed.
The application system information synchronization method of the invention has the following characteristics:
platform-crossing property: because XML and JAVA languages are cross-platform, the model based on the two technologies also has the cross-platform characteristic;
asynchrony: the service system A does not need to know whether the service system B works normally, the service system A can send messages to the JMS service assembly, and after the service system B can run normally, the service system A can automatically receive the messages from the JMS service assembly, namely, data synchronization does not need to be carried out, and both sides of synchronous data are on line at the same time, namely, the data synchronization is asynchronous;
③ loose coupling: the message is sent without considering the communication conditions of the transmitting and receiving parties and how to process the received message, and only the XML message format which is agreed by the two parties needs to be transmitted;
reliability: the asynchronism of the JMS ensures the reliability of message transmission;
expandability: due to the high loose coupling and the universality of the components, the future access of a new business system is facilitated to participate in data exchange.
