Description

Technical Field

[0001] The present invention relates to a user management system for a substation monitoring system, belonging to the technical field of substation monitoring. Background Art

[0002] The intelligent substation monitoring system is a networked integrated management system that integrates multiple subsystems responsible for centralized monitoring, control, and management of the main electrical equipment of the whole station system, including access control systems, fire protection systems, dynamic environment systems, network devices, etc. and their operating states.

[0003] Some old substations have low intelligence levels and the substation monitoring system has low integration. With the improvement of the intelligent level of the modern power grid, the upgrade and transformation of old substations has become an inevitable trend. For example, Figure 1 as shown, in the transformation process, in order to enhance its intelligence level, various intelligent substation monitoring subsystems are gradually introduced, or as Figure 2 shown, some monitoring subsystems with higher integration are directly introduced. However, they cannot completely replace the functions of the original multiple systems, resulting in the parallel operation of the new and old monitoring subsystems, leading to different user management and login verification accounts for each subsystem in a substation, which is inconvenient to use. In the process of configuring and managing user management functions such as identity verification and permission verification, different operations need to be performed on different and mutually isolated management terminals, and it is easy to cause confusion in the operation of user management of each subsystem, which not only increases the maintenance cost but also makes the management of the substation more complex. Thus, it can be seen that the user management of each subsystem of the existing substation monitoring system needs to perform user management operations separately on different and mutually isolated management terminals, which is very complex and inconvenient. Summary of the Invention

[0004] The purpose of the present invention is to provide a user management system for a substation monitoring system to solve the problem that the user management of each subsystem of the existing substation monitoring system needs to perform user management operations separately on different and mutually isolated management terminals, resulting in complexity and inconvenience.

[0006] Furthermore, the management service end further includes a maintenance interface; the maintenance interface is used to obtain the data corresponding to the operation on the subsystem management information in the management service end and send it to the management service; the management service is further used to perform corresponding processing operations on the subsystem management information in the management service end according to the data corresponding to the operation on the subsystem management information in the management service end, or output the corresponding subsystem management information to the corresponding location.

[0007] Furthermore, it further includes a user management client. The user management client is used to obtain the data corresponding to the operation on the subsystem management information in the management service end at the user management client and send it to the maintenance interface of the management service end, and is further used to send the corresponding subsystem management information output by the management service through the maintenance interface to the display interface corresponding to the user management client.

[0008] Furthermore, the user management client is further used to obtain the data corresponding to the user authentication operation at the subsystem, and send the data corresponding to the user authentication operation at the subsystem to the corresponding authentication interface, so that the authentication interface can obtain the data corresponding to the user authentication operation at the subsystem; The user management client is further used to obtain the data corresponding to the access operation that requires permission verification by the user at the subsystem, and send the data corresponding to the access operation that requires permission verification by the user at the subsystem to the corresponding permission verification interface, so that the permission verification interface can obtain the data corresponding to the access operation that requires permission verification by the user at the subsystem.

[0009] Furthermore, the ways for the authentication interface to obtain the data corresponding to the user authentication operation at the subsystem include: The authentication interface first obtains the authentication request at the subsystem, and according to the authentication request at the subsystem, sends the page corresponding to the authentication to the subsystem, and then obtains the data corresponding to the user authentication operation at the subsystem according to the operation of the user at the subsystem on the page corresponding to the authentication.

[0010] Furthermore, the ways for the authentication interface to obtain the data corresponding to the user authentication operation at the subsystem include: After the authentication interface obtains the authentication request at the subsystem, according to the authentication request at the subsystem, it sends the page corresponding to the authentication in the user management client to the subsystem, so as to obtain the data corresponding to the user authentication operation at the subsystem through the operations of the user at the subsystem on the page corresponding to the authentication.

[0011] Further, the ways for the maintenance interface to obtain the data corresponding to the operations on the subsystem management information in the management server include: The maintenance interface first obtains the subsystem management request, and according to the subsystem management request, sends the page corresponding to the subsystem management request to the sender of the subsystem management request, and then obtains the data corresponding to the operations on the subsystem management information in the management server according to the operations on the page corresponding to the subsystem management.

[0012] Further, the information on the operation permissions of the user for the subsystem includes: the classification information of the subsystem, the information on the operation permissions of different user types for various subsystems, and the information on the user type corresponding to each user.

[0013] Further, the subsystem management information also includes the information on the server where the subsystem that allows or does not allow access to the interface in the management server is located; The data corresponding to the user authentication operation at the subsystem obtained by the authentication interface is the data corresponding to the user authentication operation at the subsystem that has been determined to allow access to the authentication interface in the management server; the management service is also used to judge whether the subsystem is a subsystem that allows access to the authentication interface in the management server through the information on the server where the subsystem is located; The data corresponding to the access operation that requires permission verification by the user at the subsystem obtained by the permission verification interface is the data corresponding to the access operation that requires permission verification by the user at the subsystem that has been determined to allow access to the permission verification interface in the management server; the management service is also used to judge whether the subsystem is a subsystem that allows access to the permission verification interface in the management server through the information on the server where the subsystem is located.

[0014] Further, all the management services in the management server are carried out on the management server corresponding to the management server, and the number of management servers is greater than or equal to 1; in the case where the number of management servers is greater than 1, each management server is uniformly managed and controlled through a load balancing scheduler, and each server is scheduled according to the load conditions of each management server to balance the load of each management server; When the number of load balancing schedulers is greater than 1, one of the load balancing schedulers is the primary load balancing scheduler, and the other load balancing schedulers are secondary load balancing schedulers; the primary load balancing scheduler is used to uniformly manage and control each management server under normal working conditions, and schedule each management server according to the load conditions of each management server to balance the load of each management server; the secondary load balancing scheduler is used to replace the primary load balancing scheduler to uniformly manage and control each management server when the primary load balancing scheduler fails, and schedule each management server according to the load conditions of each management server to balance the load of each management server. The management server also includes a database; the database is divided into a primary database and a secondary database, both of which are used to store subsystem management information in the management server; the primary database is used to provide subsystem management information to the management service under normal data conditions; the data in the secondary database is synchronized with the data in the primary database, and the secondary database is used to provide subsystem management information to the management service when the data in the primary database is abnormal.

[0015] Beneficial effects: The present invention provides a new user management system for a substation monitoring system. The present invention unifies the work of the existing operation of the user management servers of each subsystem to complete the identity verification and permission verification of users in each subsystem by the identity verification interface, permission verification interface and management service in the management server of the user management system of the substation monitoring system of the present invention. There is no need to transform each subsystem of the substation monitoring system. Each subsystem only needs to be connected to the identity verification interface and permission verification interface in the management server of the user management system of the substation monitoring system. The management server of the user management system for user management of the substation monitoring system can correspondingly obtain the corresponding user operations at the accessed subsystems through the identity verification interface and permission verification interface, and perform identity verification and permission verification-related processing through the management service, so as to complete the identity verification and permission verification corresponding to the user operations at the accessed subsystems.

Specific implementation manners

[0017] The following further explains the specific implementation manners of the present invention in conjunction with the accompanying drawings.

[0018] Embodiment of the user management system of the substation monitoring system This embodiment provides a technical solution for the user management system of the substation monitoring system. This system can complete the identity verification corresponding to the identity verification interface in the management server of the user management system and the user operations at the subsystems of the connected substation monitoring system, and the permission verification corresponding to the user operations at the subsystems connected to the permission verification interface by using a unified management service. This system solves the chaotic situation of user management of multiple subsystems during the upgrade and transformation of old substations, and realizes the unified management of users of each subsystem through a unified management service, making the user management work of each subsystem simpler and more convenient.

[0019] The user management system of the substation monitoring system specifically includes a management server containing subsystem management information, an identity verification interface, a permission verification interface, and a management service; the subsystem management information includes user identity information and information on the operation permissions of users for the subsystems; The identity verification interface is used to obtain the data corresponding to the user identity verification operation at the subsystem and send it to the management service, and return the identity verification result determined by the management service based on the user identity information and the data corresponding to the user identity verification operation to the subsystem to verify the user identity at the subsystem; the permission verification interface is used to obtain the data corresponding to the access operation that requires permission verification by the user at the subsystem and send it to the management service, and return the permission verification result determined by the management service based on the information on the operation permissions of the user for the subsystem and the data corresponding to the access operation that requires permission verification by the user at the subsystem to the subsystem to verify the operation permissions at the subsystem; the subsystem belongs to the substation monitoring system. This system solves the chaotic situation of user management of multiple subsystems during the upgrade and transformation of old substations, and realizes the unified management of users of each subsystem through a unified management service, making the user management work of each subsystem simpler and more convenient.

[0020] The following specifically describes the user management system of the substation monitoring system: The user management system of the substation monitoring system includes: a management server, which contains subsystem management information, an identity verification interface, a permission verification interface, and a management service; the subsystem management information contains user identity information and information on the operation permissions of users for subsystems; among them, the subsystem belongs to the substation monitoring system. The identity verification interface is used to obtain the data corresponding to the user identity verification operation at the subsystem and send it to the management service, and return the identity verification result determined by the management service based on the user identity information and the data corresponding to the user identity verification operation to the subsystem to complete the user identity verification at the subsystem. In this embodiment, the user identity information may include the accounts of users who can request identity verification and the corresponding relationship between the accounts of these users and their passwords; the identity verification result determined according to the user identity information and the data corresponding to the user identity verification operation corresponds to whether the data corresponding to the user identity verification operation (such as the account and password entered by the user) is consistent with the account of the user and the corresponding relationship between the account password of the user in the user identity information.

[0021] In this embodiment, the specific way for the identity verification interface to obtain the data corresponding to the user identity verification operation at the subsystem is as follows: the identity verification interface first obtains the identity verification request at the subsystem, and according to the identity verification request at the subsystem, sends the page corresponding to the identity verification to the subsystem, and then obtains the data corresponding to the user identity verification operation at the subsystem according to the operations of the user at the subsystem on the page corresponding to the identity verification. This way of the identity verification interface obtaining the data corresponding to the user identity verification operation at the subsystem can provide a unified and beautiful page corresponding to the identity verification for users at different subsystems through the management server, increasing the friendliness of the human-computer interaction interface; among them, in this way, the page corresponding to the identity verification sent to the subsystem is deployed on the server side, and this way of the identity verification interface obtaining the data corresponding to the user identity verification operation at the subsystem is mainly used when the subsystem is of the B / S architecture.

[0022] In other embodiments, the manner in which the authentication interface obtains data corresponding to the user authentication operation at the subsystem may also be as follows: after the authentication interface obtains the authentication request at the subsystem, according to the authentication request at the subsystem, the authentication corresponding page in the user management client is sent to the subsystem, so as to obtain the data corresponding to the user authentication operation at the subsystem through the operation of the user at the subsystem on the authentication corresponding page. This manner of the authentication interface obtaining the data corresponding to the user authentication operation at the subsystem can still provide a unified and beautiful authentication corresponding page for users at different subsystems through the management server, increasing the friendliness of the human-computer interaction interface; among them, in this manner, the authentication corresponding page is implemented on the client side, and the data required in the page is obtained by calling the interface of the server side. This manner of the authentication interface obtaining the data corresponding to the user authentication operation at the subsystem is mainly adopted when the subsystem is of the C / S architecture. The permission verification interface is used to obtain the data corresponding to the access operation that requires permission verification by the user at the subsystem and send it to the management service, and return the permission verification result determined by the management service based on the information about the user's operation permission for the subsystem and the data corresponding to the access operation that requires permission verification by the user at the subsystem to the subsystem to complete the operation permission verification at the subsystem. In this embodiment, the information about the user's operation permission for the subsystem includes: subsystem classification information, information about the operation permissions of different user types for various subsystems, and information about the user type corresponding to each user. The permission verification result determined according to the information about the user's operation permission for the subsystem and the data corresponding to the access operation that requires permission verification by the user at the subsystem is the result of judging whether the access operation that requires permission verification by the user at the subsystem conforms to the operation permission according to the information about the user's operation permission for the subsystem.

[0023] In this embodiment, the subsystem management information further includes information about the servers where the subsystems that are allowed or not allowed to access the interfaces in the management server are located; for example, the information about the servers where the subsystems that are allowed to access the interfaces in the management server are located includes the IP and name of the servers where the subsystems that are allowed to access the interfaces in the management server are located, which is equivalent to a white list of subsystem addresses set for the interfaces in the management server (which can be at least one of the authentication interface and the permission verification interface); the information about the servers where the subsystems that are not allowed to access the interfaces in the management server are located includes the IP and name of the servers where the subsystems that are not allowed to access the interfaces in the management server are located, which is equivalent to a black list of subsystem addresses set for the interfaces in the management server (similarly, it can be at least one of the authentication interface and the permission verification interface); Therefore, the data corresponding to the user authentication operation at the subsystem obtained by the authentication interface is the data corresponding to the user authentication operation at the subsystem that has been determined to be allowed to access the authentication interface in the management server; the management service is also used to determine whether the subsystem is a subsystem that is allowed to access the authentication interface in the management server based on the information of the server where the subsystem is located; The data corresponding to the access operation that requires permission verification by the user at the subsystem obtained by the permission verification interface is the data corresponding to the access operation that requires permission verification by the user at the subsystem that has been determined to be allowed to access the permission verification interface in the management server; the management service is also used to determine whether the subsystem is a subsystem that is allowed to access the permission verification interface in the management server based on the information of the server where the subsystem is located.

[0024] Generally, the information of the server where the subsystem that is allowed to access the authentication interface in the management server is located is the same as the information of the server where the subsystem that is allowed to access the permission verification interface in the management server is located; similarly, the information of the server where the subsystem that is not allowed to access the authentication interface in the management server is located is the same as the information of the server where the subsystem that is not allowed to access the permission verification interface in the management server is located, that is, the subsystem whose location (i.e., the information of the server where it is located) conforms to the whitelist corresponding to the interface can access the corresponding interface, while the subsystem whose location conforms to the blacklist corresponding to the interface is not allowed to access the corresponding interface.

[0025] In this embodiment, the management server also includes a maintenance interface; the maintenance interface is used to obtain the data corresponding to the operation on the subsystem management information in the management server and send it to the management service; the management service is also used to perform corresponding processing operations on the subsystem management information in the management server or output the corresponding subsystem management information to the corresponding location according to the data corresponding to the operation on the subsystem management information in the management server. Performing corresponding processing operations on the subsystem management information in the management server, for example, performing corresponding addition, deletion, modification and other processing operations on the subsystem management information in the management server; outputting the corresponding subsystem management information to the corresponding location, for example, outputting the query result of the subsystem management information in the management server to the corresponding location; In this embodiment, the user management system of the substation monitoring system further includes a user management client. The user management client is used to obtain the data corresponding to the operation on the subsystem management information in the management server on the user management client and send it to the maintenance interface of the management server, and is also used to send the corresponding subsystem management information output by the management service through the maintenance interface to the display interface corresponding to the user management client. The user management client facilitates the operation of the management personnel on the subsystem management information in the management server.

[0026] In this embodiment, the user management client is further configured to obtain the data corresponding to the user authentication operation at the subsystem, and send the data corresponding to the user authentication operation at the subsystem to the corresponding authentication interface, so that the authentication interface can obtain the data corresponding to the user authentication operation at the subsystem; The user management client is further configured to obtain the data corresponding to the access operation that requires permission verification by the user at the subsystem, and send the data corresponding to the access operation that requires permission verification by the user at the subsystem to the corresponding permission verification interface, so that the permission verification interface can obtain the data corresponding to the access operation that requires permission verification by the user at the subsystem.

[0027] The user management client can select the interface corresponding to the data based on the data corresponding to the user authentication operation at the subsystem or the access operation that requires permission verification, and then send the obtained data to the corresponding interface, so that the corresponding interface can obtain the corresponding data; each interface provided by the server is encapsulated in the user management client. The user management client provides a preset dynamic library and header file for the subsystem. The subsystem can select the required interface through the header file provided by the user management client, and then call the required interface in the management server by loading the dynamic library, so that the subsystem can quickly access the corresponding interface, facilitating the connection between the subsystem and the interface.

[0028] In this embodiment, the specific manner in which the maintenance interface obtains the data corresponding to the operation on the subsystem management information in the management server is as follows: The maintenance interface first obtains the subsystem management request, and according to the subsystem management request, sends the page corresponding to the subsystem management request to the sender of the subsystem management request, and then obtains the data corresponding to the operation on the subsystem management information in the management server according to the operation at the page corresponding to the subsystem management. This way of the maintenance interface obtaining the data corresponding to the operation on the subsystem management information in the management server can provide a unified and beautiful page for the subsystem management (i.e., the operation on the subsystem management information in the management server, and the subsystem management request is the request corresponding to the operation on the subsystem management information in the management server) to the users at different operation ends through the management server, increasing the friendliness of the human-computer interaction interface.

[0029] In this embodiment, the deployment schematic diagram of the management server is as Figure 3 shown. All the management services in the management server are in the management server corresponding to the management server (the management server corresponds Figure 3It is carried out on the user management service in [ ], and the number of management servers is greater than or equal to 1; when the number of management servers is greater than 1, each management server (the management servers greater than or equal to 1 constitute the user management service server group) is uniformly managed and controlled through a load balancing scheduler, and each server is scheduled according to the load conditions of each management server to balance the load of each management server.

[0030] In this embodiment, when the number of load balancing schedulers is greater than 1, referring to Figure 3 , the load balancing schedulers greater than or equal to 1 constitute the load balancing scheduler server group, and one of the load balancing schedulers is the main load balancing scheduler, and the other load balancing schedulers are slave load balancing schedulers; the main load balancing scheduler is used to uniformly manage and control each management server under normal working conditions, and schedule each management server according to the load conditions of each management server to balance the load of each management server; the slave load balancing scheduler is used to replace the main load balancing scheduler to uniformly manage and control each management server when the main load balancing scheduler fails, and schedule each management server according to the load conditions of each management server to balance the load of each management server.

[0031] In this embodiment, the management server also includes a database; referring to Figure 3 , the databases greater than or equal to 1 constitute the data storage server group, and the databases are divided into a main database and a slave database, both of which are used to store the subsystem management information in the management server; the main database is used to provide the subsystem management information to the management service under normal data conditions; the data in the slave database is synchronized with the data in the main database, and the slave database is used to provide the subsystem management information to the management service when the data in the main database is abnormal.

[0032] In this embodiment, the structural example diagram of the database of the management server is as shown in Figure 4 . The user identity information in the subsystem management information is stored in the user table in the database (corresponding to the user user in Figure 4 ). The subsystem classification information in the information about the operation permissions of the user for the subsystem, the information about the operation permissions of different user types for various subsystems, and the information about the user type corresponding to each user are respectively stored in the subsystem classification table in the database (corresponding to the subsystem classification subsystem in Figure 4 ), the role - subsystem relationship table (corresponding to the userrole in Figure 4 ) and the user - role relationship table (corresponding to the usersystem in Figure 4 ); the subordinate list of the user - role relationship table includes the role table (corresponding to Figure 4The subordinate list of the classification table of the role userrole) subsystem in includes the basic permission table storing the permission information that the subsystem can be operated on (corresponding to Figure 4 the basic permission permission) in; The workstation table stored in the database that allows or does not allow access to the information of the server where the subsystem of the management server interface is located (corresponding to Figure 4 the workstation station) in.

[0033] In this embodiment, the database also stores an operation log table for recording user information changes and requests (corresponding to Figure 4 the operation log table log) in; In this embodiment, Figure 3 the interfaces and web pages in are the access entrances of the subsystems of the substation monitoring system to the management server. If the subsystem is a C / S architecture application, the subsystem accesses the management server through the Figure 3 interface in. If the subsystem is a B / S architecture website, the subsystem accesses the management server through the web page.

[0034] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention.
