The underlying support platform mainly includes the JavaEE environment on which the system runs: WEB container and Spring (the name of a JAVAEE container) and other middleware, as well as ESB for system integration and expansion Middleware; business support platform includes workflow engine/tool, report engine/tool, system maintenance tool, department organization and authority management, as well as tool library, component library and For the public interface library, only the JEE environment and basic business support modules are deployed in the first stage. See Figure 1.

The description of the architecture platform of the substation equipment scheduling monitoring information processing system in the above embodiment is as follows:

⑴The underlying support platform

①ESB-based support platform

The standard integration goal between loosely coupled services and applications is achieved by using an Enterprise Service Bus (ESB). ESB has technical characteristics such as interoperability, openness, and platform independence. Its core technologies and standards are Web Services and SOA, and its characteristics are: service-oriented architecture, message-oriented architecture, and event-driven architecture. The overall structure is shown in Figure 2.

A service-oriented architecture (SOA) technology is a collection of services that communicate with each other, such as passing data from one service to another or coordinating activities between one or more services. SOA can deconstruct large-scale applications in the system into building blocks or small modular functional components or services, which can be used by different personnel inside and outside the system to unify business processes.

The intelligent scheduling support module adopts the SOA method to provide services for the entire system, which is convenient for the arbitrary expansion of the system and the external services of the functional modules, laying a solid foundation for the future upgrade of the system.

ESB adopts the 61968 and 61970 standards for system modeling, and adopts international standards for the access of different systems to facilitate subsequent maintenance. When a new system is connected, it can be easily connected as long as it follows the standard, reducing work quantity. Through the ESB and the implementation of standard-compliant interfaces, the business flow between the upper and lower levels and between different departments can be accelerated, and data sharing can be accelerated.

②JavaEE architecture

Taking into account the overall needs of the system, the research on the comprehensive calculation and management technology of dispatching and monitoring information is implemented based on the BS model. All functions are implemented on the WEB server.

Scheduling and monitoring information comprehensive computing management technology research is based on JavaEE platform, using Apache/Tomcat server, using Spring+IBatis/Hibernate+DWR technology in the background, making full use of the rich functions of JavaEE platform and strong support for enterprise application development, this mode gives the system a powerful The expansion capability and simple maintenance requirements provide a strong guarantee for project implementation.

(2) J2EE provides a good mechanism for building a scalable, flexible and easy-to-maintain business system:

① Retain existing IT assets:

As companies must adapt to new business needs, it is important to leverage existing investments in enterprise information systems rather than reinvent the wheel. Thus, a server-side platform mechanism that builds on existing systems in a progressive (rather than radical, blanket negation) manner is what companies need. The J2EE architecture can make full use of the original investment of users, such as BEA Tuxedo, IBM CICS, IBM Encina, Inprise VisiBroker and Netscape Application Server used by some companies. This is possible because J2EE has broad industry support and the participation of some key 'enterprise computing' vendors. Each vendor offers existing customers an upgrade path into the portable J2EE world without throwing away existing investments. Because products based on the J2EE platform can run on almost any operating system and hardware configuration, existing operating systems and hardware can also be retained.

② Efficient development:

J2EE allows companies to hand over some common and tedious server-side tasks to intermediate suppliers. In this way, developers can concentrate on how to create business logic, which shortens the development time accordingly. Advanced middleware vendors provide the following complex middleware services: State management service - allowing developers to write less code and not care about how to manage state, so that program development can be completed faster.

Persistent Services - allows developers to write applications without coding data access logic, resulting in lighter, database-independent applications that are easier to develop and maintain.

Distributed shared data object CACHE service - allows developers to compile high-performance systems, greatly improving the scalability of the overall deployment.

③Support heterogeneous environment:

J2EE can develop portable programs deployed in heterogeneous environments. J2EE-based applications do not depend on any specific operating system, middleware, or hardware. Therefore, a well-designed J2EE-based program can be deployed to various platforms only after being developed once. This is critical in a typical heterogeneous enterprise computing environment. The J2EE standard also allows customers to order ready-made third-party components that are compatible with J2EE and deploy them in a heterogeneous environment, saving the cost of developing the entire solution by themselves.

④ Scalability:

Enterprises must choose a server-side platform that provides excellent scalability to meet the large number of new customers who conduct business operations on their systems. Applications based on the J2EE platform can be deployed to various operating systems. For example, it can be deployed to high-end UNIX and mainframe systems, which can support 64 to 256 processors in a single machine. (This is beyond the reach of NT servers) Suppliers in the J2EE field provide a wider range of load balancing strategies. It can eliminate bottlenecks in the system and allow integrated deployment of multiple servers. This deployment can reach thousands of processors, enabling a highly scalable system to meet the needs of future business applications.

⑤ Stable usability:

A server-side platform must be able to operate around the clock to meet the needs of the company's customers and partners. Because the Internet is globalized and ubiquitous, even planned outages at night may cause serious losses. Unplanned downtime can have catastrophic consequences. J2EE is deployed into a reliable operating environment where they support long-term availability. Some J2EEs are deployed in the WINDOWS environment, and customers can also choose operating systems with better robustness (stability) such as Sun Solaris and IBM OS/390. The most robust operating systems achieve 99.999% availability or as little as 5 minutes of downtime per year. This is an ideal choice for real-time highly commercial systems.

Spring was created to solve the complexity of enterprise application development. It is a lightweight Inversion of Control (IoC) and Aspect-Oriented (AOP) container framework. Spring uses basic JavaBean to complete things that could only be done by EJB before, and has the characteristics of portability, easy use, easy expansion, and wide application. IBatis is an open source object-relational mapping framework. It encapsulates JDBC with a very lightweight object, so that Java programmers can use object programming thinking to manipulate the database as they like. DWR dynamically generates Java classes into Javascript through Ajax, making calling JAVA methods on the browser side as direct and convenient as calling ordinary JS methods. This method of remote calling functions from Java to JavaScript makes DWR use a conventional RPC mechanism very similar to RMI or SOAP. The advantage of DWR is that it can run on web pages without any web browser plug-ins.

The front end adopts RIA/ExtJS technology to provide powerful and flexible interactive capabilities of the system, making the system usable like a desktop system. On this basis, the E8800 basic platform component library and corresponding tools provide powerful enrichment and expansion, making the front-end implementation convenient, fast, rich and powerful.

The system database adopts ORACLE database, which provides information transmission and historical query between provincial and ground surveys.

The web layer uses the currently popular rich client technology (RIA) to develop a friendly interface system for human-computer interaction. The technologies involved are mainly ExtJS and DWR.

ExtJS is an Ajax framework, written in javascript, used to create rich and colorful web application interface on the client side. ExtJS can be used to develop RIA, that is, rich client AJAX applications. ExtJS is mainly used to create the front-end user interface and is a front-end ajax framework that has nothing to do with background technology. Therefore, ExtJS can be used in applications developed in various development languages such as .Net, Java, and Php. ExtJs was originally based on YUI technology, which perfectly integrated JQuery, Prototype and YUI.

The biggest feature that distinguishes ExtJS from other Ajax frameworks is that it provides rich and easy-to-use UI components and a unified and beautiful style library.

ExtJs has won great honors in Web UI, but its Client UI alone cannot complete a complete Web application. It also needs a bridge to facilitate communication with background server programs. DWR is the right architecture for this.

DWR (Direct Web Remoting) is a remote server-side Ajax open source framework for improving the interaction between web pages and Java classes, which can help developers develop websites that include AJAX technology. It can allow the code in the browser to use the JAVA function running on the WEB server, just as in the browser.

In order to ensure the high reliability, maintainability and scalability of the program, the DIC server has designed a flexible and powerful platform architecture. The platform architecture involves the following well-known frameworks and technologies.

Spring was created to address the complexities of enterprise application development. One of the main strengths of the framework is its layered architecture, which allows you to choose which components to use while providing an integrated framework for Java EE application development.

The Spring Framework is a layered architecture consisting of 7 well-defined modules. The Spring module is built on the core container. The core container defines the way to create, configure and manage beans. Each module (or component) that makes up the Spring framework can exist alone or be implemented in conjunction with one or more other modules. The function of each module is as follows:

Core container: The core container provides the basic functionality of the Spring framework. The main component of the core container is the BeanFactory, which is an implementation of the factory pattern. The BeanFactory uses the Inversion of Control (IOC) pattern to separate an application's configuration and dependency specification from the actual application code.

Spring context: Spring context is a configuration file that provides context information to the Spring framework. The Spring context includes enterprise services such as JNDI, EJB, email, internationalization, validation, and scheduling functions.

Spring AOP: Through the configuration management feature, the Spring AOP module directly integrates aspect-oriented programming functions into the Spring framework. Therefore, any object managed by the Spring framework can be easily AOP-enabled. The Spring AOP module provides transaction management services for objects in Spring-based applications. By using Spring AOP, you can integrate declarative transaction management into your application without relying on EJB components.

Spring DAO: The JDBC DAO abstraction layer provides a meaningful exception hierarchy that can be used to manage exception handling and error messages thrown by different database vendors. The exception hierarchy simplifies error handling and greatly reduces the amount of exception code that needs to be written (such as opening and closing connections). Spring DAO's JDBC-oriented exceptions follow the general DAO exception hierarchy.

Spring ORM: The Spring framework inserts several ORM frameworks to provide ORM object relational tools, including JDO, Hibernate and iBatis SQL Map. All of these follow Spring's generic transaction and DAO exception hierarchies.

Spring Web Module: The Web Context module builds on the Application Context module and provides a context for Web-based applications. Therefore, the Spring framework supports integration with Jakarta Struts. The web module also simplifies the work of handling multipart requests and binding request parameters to domain objects.

Spring MVC framework: The MVC framework is a full-featured MVC implementation for building web applications. Through the strategy interface, the MVC framework becomes highly configurable, and MVC accommodates a large number of view technologies, including JSP, Velocity, Tiles, iText, and POI.

The features of the Spring Framework can be used in any Java EE server, and most of the features are also suitable for unmanaged environments. The core point of Spring is to support reusable business and data access objects that are not bound to specific J2EE services. There is no doubt that such objects can be reused between different J2EE environments (Web or EJB), stand-alone applications, and test environments.

iBatis is a persistence layer framework that can customize SQL, stored procedures and advanced mapping. iBatis eliminates most of the JDBC code, manual parameter setting and result set retrieval. iBatis only uses simple XML and annotations to configure and map basic data types, Map interfaces and POJOs to database records. Compared with "one-stop" ORM solutions such as Hibernate and Apache OJB, ibatis is a "semi-automated" ORM implementation. iBatis makes the persistence process of the program reusable, configurable, easy to write and manage, and easy to debug.

⑵Business support platform

The E8800 power operation platform is used to improve the system's processing capacity and performance, reduce the difficulty of system implementation, increase the speed of system development, improve the reliability and stability of the system and the standardization of the program. The platform provides all-round support for the realization of business on both front-end and back-end: the back-end adopts Spring+IBatis/Hibernate+DWR technology, making full use of the rich functions of the J2EE platform and strong support for enterprise application development. This model gives the system a powerful Scalability and easy maintenance requirements. The platform provides a wealth of tools to provide convenient and fast support for the operation and management business in terms of data model definition, entity relationship maintenance, user interface model definition, and automatic code generation. The entity model is based on JavaBean technology. While following the State Grid specification, it implements a multi-layer architecture of business functions with the help of JavaBean related technologies.

The front-end part of the platform adopts RIA/ExtJS/SVG technology, provides a rich component library and customization/maintenance tools, provides the system with powerful performance capabilities and flexible and convenient interactivity, and makes the system fully reach the usability of desktop programs.

The system platform supports services mainly through the E8800 basic platform. The E8800 basic platform provides a set of support libraries with rich and powerful functions, stable and reliable operation, and convenient and flexible use for WEB application development. Its design purpose is: to provide convenient and easy-to-use tools for complex businesses, so as to reduce the complexity of such business implementation and improve its reliability; to provide colorful, stable and reliable data rendering components for the front end; to provide Standardized and reliable implementation; organize and integrate relevant page styles, page materials, page templates, code templates, etc., to facilitate the rapid implementation of business applications.

The E8800 basic platform consists of tool library, component library, public interface library, resource library, and public module library. The platform tool library includes: workflow customization tools, report tools, unified database maintenance tools, general form generation tools, etc.; the component library includes HTML components, EXT extension components, self-implementing WEB components, etc. The latter includes: chart components, tables Components, image display components, Office components, small GUI components, etc.; the public interface library includes interface packages for database/data interaction (JSON, encryption...), unit testing, exception handling, logs, messages, and front-end SVG, HTML, etc. processing .

The following is a description of several important support tools:

①E8800 platform component library, see Figure 3 and Figure 4

Chart components, table components, and image display components provide powerful support for information display.

②E8800 platform tool library, see Figure 5.

Workflow customization tools, reporting tools, unified database maintenance tools, and general form generation tools provide great convenience for business design and greatly increase the speed of implementation.

①Workflow engine

In order to make the business related to the comprehensive calculation and management technology research of dispatching monitoring information have enough flexibility, it is necessary to apply workflow technology to streamline business information processing. The workflow engine is developed based on component technology, and realizes the startup of workflow instances, task scheduling, allocation and coordination, dynamic adjustment of workflow, recording of work history and management of workflow affairs. The whole workflow service includes operation service module, activity management module, message service module, event management module, log/history management module, process monitoring module and work list management module, etc.

The graph-based workflow system complies with the Workflow Management Consortium (WFMC) standard and implements all processes of workflow definition, execution and monitoring. The graphical customization interface is intuitive and easy to operate, and the transfer relationship is clear at a glance.

In addition to meeting the functions of sending and receiving work tasks according to the conventional workflow, the system also has the sender recycles the task due to misoperation, and the receiver cannot complete the task due to other things, and the original sender needs to arrange for others to complete the task. There are also functions such as returning tasks; there are also some businesses that require special handling due to emergencies, which can be directly skipped to any subsequent step without following the set process, so as to realize the flexible flow of business processes.

②General report engine

The report management function provides report compilation, management and query mechanisms for each application of the system, facilitates various applications to realize the report function, has management functions such as report change and expansion, and supports flexible data extraction, organization, statistics and expression functions.

③System management and maintenance module

At the same time, it can summarize, analyze and generate reports for all monitored data.

④System security management module

The system platform has a complete security service mechanism, and has multiple security protection measures for all protected resources (databases, screens, services, etc.) to ensure system security.

Security management covers multiple levels and modules of the platform, including user rights management and operation log security services for the entire system. Based on job responsibilities and roles, the system realizes the user identity registered in the system to use the system. The functions that users can complete are their business needs. Multiple roles can be defined according to different businesses and positions.

User authority management is mainly to limit the operation authority of the system function after the user logs in. By setting the user's department, position, and role to control the user's access to different business system levels, including the security management of the production department and system function modules, etc., to achieve The relationship between users and their roles and functions such as granting corresponding application permissions to different roles.

The description of the business functions of the substation equipment scheduling and monitoring information processing system in the above embodiment is as follows:

(1) Monitoring information intelligent management module, see Figure 6.

The whole system adopts B/S structure. The ground survey, maintenance company, and Electric Power Research Institute report the monitoring information through the browser page and store it in the database. The provincial bureaus query and report the statistical results through the browser page, and export the report to the national survey.

①Monitoring information reporting

Simple and easy-to-use office-style substation reporting interface, all forms include "Prefecture and County Control Center Centralized Monitoring Substation Monitoring and Alarm Information", "Prefecture and County Control Center Equipment Defects", "Prefecture and County Control Center Centralized Monitoring Substation Equipment Defects Situation", "Professional Management Personnel of Equipment Monitoring", "Conditions of Equipment Monitoring Operators", "Statistics of Monitoring Information of Centralized Monitoring Substation", "Statistics of Switching Operation of Regulatory Institutions", "Statistics of Fault Handling Time of Centralized Monitoring Substation" , completely presented on one page, after logging in, reporting personnel from all over the country can report the monitoring information of this month at one time, and can also query the monitoring information of previous months through the date. In order to reduce the user's workload and avoid repetitive filling work, the information report provides a convenient copy and paste function, and the data can be easily imported into the WEB interface.

The information reporting involves the review of the provincial bureau. The information that has been reviewed cannot be modified by the local surveys. However, the data that has not been reviewed can be displayed by the local surveys, modified on the basis of the original reported data, and the data will be released again after completion. For example, the display interface of Gansu equipment monitoring and management system can be as follows:

Monitoring system monthly information statistical analysis table

② Statistical analysis and export of provincial monitoring information

The statistical report that needs to be reported to the national survey by the provincial survey is automatically generated based on the data of the local survey, and the information reported by the local survey will be summarized in the corresponding table, and the data of the local survey will be accumulated for reporting to the national survey. You can also export an Excel table on this page for subsequent processing. Provincial surveys and local surveys are granted different roles and permissions. Local survey users cannot view the provincial survey summary page. Provincial survey users can also query the statistical information of previous months. After reviewing the information of the current month, they can click Save. Local survey users cannot To modify and upload again, you can only query. For example, the display interface of the Gansu equipment monitoring and management system can also be as follows:

③The list of monitoring information is dynamically increased

In view of the fact that new columns will be added to the reporting information monitoring table to count new information, the interface of the ground and provincial survey tables is dynamically generated based on the platform's general table assistant, and the page can be regenerated when new columns need to be added.

The table interface is generated by an Excel table. We have slightly modified the original Excel table, and added on the basis of this Excel table when it is necessary to add columns dynamically. Then use the common form tool to generate the configuration and file of the new form interface, as shown in Figure 7. Just open the modified Excel file in this interface, see Figure 8. Click the preview panel and generate a new report interface as follows:

Monitoring system monthly information statistical analysis table

Note that if the number of dynamically added columns exceeds the number of original spare columns, you need to add the corresponding columns in the database. After adding the spare columns, you can add commet to facilitate future queries.

The regenerated report configuration file is a text file, which can be edited with any text editor. The regenerated configuration file needs to be bound to the first field so that the program can identify and process it. "For example, you need to bind the "ZZD" field, and this work needs to be handled by bureau personnel, as shown in Figure 32.

In addition, there is another configuration file that needs to add dynamically added column names. For example, if two columns are dynamically added in "Equipment Defects of Prefectural and County Control Centers", you need to add BY1 and BY2 in the configuration file so that the program can identify and process them. The same is true again when adding a new column, eg Figure 33.

④ Document management

Whether it is monitoring information management or typical monitoring information tables of substations, it replaces documents in a brand-new way, making work easier, but traditional documents are still an indispensable function as a backup. Document uploading, auditing and Management is still a very important way of exchanging information between local surveys and provincial surveys. In the reporting of monitoring information, the local survey can still upload the information in the form of a document for review and archiving, and the local survey can also upload the typical table in the form of Excel as a document. The document management module manages and maintains all documents, including the "time stamp" attribute, see Figure 9. Refer to Figure 10 for the interface of uploading, downloading and online browsing of substation data files. Refer to Figure 11 for online browsing of reported and downloaded documents.

Maintenance and management of document catalogs: regional commissioners and county commissioners can log in and select their own substation catalogs to upload relevant drawings, tables, dispatching naming files, parameter data, operation ledgers, commissioning records and other documents, see Figure 12.

Local dispatchers and county dispatchers can upload, modify, and delete relevant data of their substations, but can only browse relevant data of other substations.

For other types of documents, you can dynamically add them through the maintenance of the data directory. After adding the corresponding directory, the provincial administrator can also perform permission-related operations to set visibility and invisibility for different departments and personnel. Security management, see Figure 13.

(2) Substation terminal basic management module, see Figure 14.

Substation terminal basic management and monitoring information intelligent management are based on the same platform and the same B/S structure. After the basic ledger data is imported into the database, the typical substation monitoring information form template issued by the State Grid is imported into the system. Users can The page conveniently selects the required device type, clicks on the description to add the device, and finally automatically generates a standard table that meets the national grid standards.

① "Basic ledger information

The basic ledger data related to the substation name, dispatching unit, territorial location, on-site manufacturer, and access time are imported into the database through Excel, and there is no need to manually input when adding a typical table, see Figure 15.

After importing the relevant plant names and dispatching units, there will be relevant data catalogs. After each substation uploads relevant documents, relevant materials can be found in the data catalog management, and can be downloaded and previewed, see Figure 16.

②Automatic generation of standard table

Use three steps to enter the device and export the form

Input and select the factory station name on the cover page, the dispatching unit will automatically correspond, and all the factory station names have been imported through Excel. If there are factories that have not been entered, you can click the name of the factory to select the factory that has already entered some equipment, and click Next to enter the equipment entry interface, see Figure 17. The equipment entry interface can respectively enter telemetry, remote signaling, remote control/remote adjustment related equipment, see Figure 18.

Clicking on a device type will list all device types for selection, this device type is extracted from the specification table. Here, the equipment type is selected according to the Excel analysis of the typical substation monitoring information table template issued by the State Grid, and the XML file required by the system is generated and then mapped to the ExtJS component. See Figure 19 and Figure 20.

After selecting the corresponding device type, the telemetry point name corresponding to the device will appear (take telemetry as an example), click the drop-down box of the device name and the entered device will appear, see Figure 21.

Select one to obtain multiple telemetry names and click the (<=) button to add. If you want to add or delete telemetry points of existing devices, after selecting the device name, the telemetry point name corresponding to this device will appear in the left box. Use (=>) and (<=) to delete, after completion, enter the device name and click Add to store the device. Remote signaling and remote control adopt similar operations. After completing the entry, click Next to preview the form as follows:

If you find an error, you can click Back to modify it. Click "Export Table" to export the Excel table, see Figure 22.

③Typical point table management

The typical monitoring information table of the substation is based on the "Regulatory Interaction Information Specification" issued by the State Grid Corporation. In the second step above, the equipment type and point description are dynamically generated according to the template issued by the State Grid. Since the standards of the State Grid will be continuously revised, And each province and region also has its own particularity, so the selected equipment type and point description are automatically generated based on the XML file, and the XML file is generated based on the template released by the State Grid, and the XML file can be regenerated after the template is updated.

The midpoint description of the template of the typical information monitoring table of the State Grid is not associated with the device name, which will add a lot of complicated work in the process of creating the Excel table. By adding a matching rule base in the management of the typical monitoring information table of the substation, according to the equipment The rules of type and point description, and automatically complete the point description when adding the device name, achieve the purpose of simplifying the work.

⑶ Security management module

① "Organization rights management

After the project is deployed, it is necessary to assign different authorities to different local surveys and provincial surveys, so as to distinguish the data release of different local surveys. Local surveys are presented as provincial survey departments, and the release of local survey data will be linked to departments and personnel, see Figure 23.

It is possible to classify the upper and lower departments, add personnel belonging to the department, add roles, and assign roles to existing personnel. Permissions are an important part of security management, and have been analyzed in detail during system design.

②Menu management

As an administrator role, the Provincial Commissioner has more functions to modify than the Earth Surveyor, Electric Power Research Institute, and maintenance company. It needs to review the statistical data of the equipment monitoring information report, perform the automatic generation of the table, and assign role authorization to the subordinate departments and personnel. These correspond to different page menus, and these menus are only visible to the provincial commissioning administrator, but not to the lower-level parts. Each functional module can be configured through the menu management function, see Figure 24.

The addition, deletion and modification of menus can be dynamically managed through the interface. For the allocation of parent menus and submenus, the sorting of menus can be completed by simple clicks, see Figure 25.

③Comprehensive display query

The comprehensive display query is based on the monitoring data uploaded by local surveys. When uploading, an interface similar to office style is adopted for the convenience of input, and all related tables are displayed together by month, which does not show the correlation and comparison of data well. , Comprehensive display query Statistical analysis of four key table data of alarm information statistics, equipment defect statistics, switching operation statistics and fault processing time, using intuitive charts to display, can well mine the correlation of data, To help with decision making, see Figure 26. Alarm information query, display accident alarm and abnormal alarm data for 12 months in a selected region, as well as statistical data for one year, see Figure 27. Defect information query, using curves and tables to display the data of critical defects, serious defects and general defects in selected regions for 12 months a year, as well as statistical data for one year, including: total number of defects found, total number of defects eliminated, defect processing rate , Defect processing timeliness, etc., see Figure 28.

Switching operation information query, using tables, bar graphs, and pie charts to display the switching operation information of the selected area for one year, including: monitoring the total number of remote operations, monitoring the total number of successful remote operations, monitoring the number of remote voltage regulation operations, monitoring Refer to Figure 29 for the number of switching and switching operations of the remote main equipment, the number of remote operations for other equipment monitoring, etc.

The substation monitoring information query module uses visual means to intuitively display the monitoring information related to the designated ground survey: the total number of monitoring information, the number of substations with standardized monitoring information, the number of substations that transmit monitoring information by means of "remote browsing, direct transmission of alarms", and different monitoring information. The number of substations connected to the function realization mode, the number of centralized monitoring substations that realize AVC, etc.
