Description

Technical Field

[0001] The present invention belongs to the technical field of power grid dispatching automation, and in particular relates to a service configuration method and system in a power grid dispatching automation system. Background Art

[0002] Service-Oriented Architecture (SOA) has been widely adopted in power grid dispatch automation systems. By encapsulating functions into services, business requirements are met. In the next-generation power grid technical support system, each service has its own configuration parameters that need to be maintained. These configuration parameters are an important component of the service.

[0003] Currently, each service maintains its own configuration parameters through configuration files. Changes to these parameters require manual modification of the configuration files and restarting the service. Each service may be deployed on multiple machines simultaneously, so modifying a single configuration parameter requires manually modifying the configuration files on multiple machines. This is cumbersome and can cause the configuration files on each machine to become out of sync. Summary of the Invention

[0004] The purpose of the present invention is to provide a service configuration method and system in a power grid dispatching automation system to solve the technical problem in the prior art that when modifying a certain configuration parameter, it is necessary to manually modify the configuration files on multiple hosts. This operation is cumbersome, the modification does not take effect immediately, and may cause the configuration files on each host to be out of sync.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, a service configuration method in a power grid dispatching automation system is provided, wherein a service configuration management process is deployed in a service configuration center, and a service configuration change process is deployed in each host. The method is executed by the service configuration management process, including: responding to a maintenance request for service information or service configuration information, maintaining the service information or service configuration information in a database, and writing a change record of the service information or service configuration information into a cache.

[0007] Furthermore, the service information includes: at least one of service ID, service name, version number, scene, scene instance, sub-scene, sub-scene instance and manufacturer; the service configuration information includes: at least one of service ID, configuration item and configuration value.

[0008] Furthermore, the maintenance request for the service information or service configuration information comes from a graphical interface or a command line interface.

[0009] Secondly, a service configuration method in a power grid dispatching automation system is provided, wherein a service configuration management process is deployed in a service configuration center, and a service configuration change process is deployed in each host. The method is executed by the service configuration change process, including: reading the full amount of service information and service configuration information from the database at startup, and writing them into the shared memory of the host where the service configuration change process is located; reading the cache in real time, and judging whether there is a change record of the service information or service configuration information in the cache. When the judgment result is "yes", reading the latest service information or service configuration information from the database, and writing them into the shared memory of the host where the service configuration change process is located.

[0010] Furthermore, each service queries service information and service configuration information from the shared memory, including: querying the service information list, querying service information according to the service ID, querying the service configuration list according to the service ID, querying the configuration value according to the service ID and configuration item, and querying the service information list according to the configuration item and configuration value.

[0011] Furthermore, each service determines whether the service configuration has been changed by querying the service configuration information in the shared memory in real time.

[0012] According to a third aspect, a service configuration system is provided in a power grid dispatching automation system, wherein a service configuration management process is deployed in a service configuration center, and a service configuration change process is deployed in each host. The method is executed by a service configuration change process, and includes: a service configuration management process for responding to maintenance requests for service information or service configuration information, performing service information maintenance or service configuration information maintenance in a database, and writing change records of the service information or service configuration information into a cache; a service configuration change process for reading the full amount of service information and service configuration information from the database upon startup, and writing them into the shared memory of the host where the service configuration change process is located; and further for reading the cache in real time, and determining whether there is a change record of the service information or service configuration information in the cache. When the determination result is "yes", the latest service information or service configuration information is read from the database, and written into the shared memory of the host where the service configuration change process is located.

[0013] Furthermore, it also includes a service configuration query interface, which is used for each service to query service information and service configuration information from the shared memory, including: querying the service information list, querying service information based on the service ID, querying the service configuration list based on the service ID, querying the configuration value based on the service ID and configuration item, and querying the service information list based on the configuration item and configuration value.

[0014] Furthermore, it also includes a service configuration change subscription interface, which is used for each service to determine whether the service configuration has changed by querying the service configuration information in the shared memory in real time.

[0015] Compared with the existing technology, the beneficial effects achieved by the present invention are as follows: the present invention uniformly maintains service information and service configuration information in the service configuration center, and each service queries the service configuration and subscribes to configuration change information through the interface. When a certain configuration parameter is modified, only one modification is required to achieve synchronous update of all hosts, without the need to restart the service, and there is no problem of unsynchronized configuration files on each host. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of the main framework of a service configuration system in a power grid dispatching automation system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] Example 1:

[0019] A service configuration method in a power grid dispatching automation system, wherein a service configuration management process is deployed in a service configuration center, and a service configuration change process is deployed in each host. The method is executed by the service configuration management process and includes:

[0020] In response to a maintenance request for service information or service configuration information, maintaining the service information or service configuration information in a database, and writing a change record of the service information or service configuration information into a cache;

[0021] The method is executed by the service configuration change process and includes:

[0022] At startup, the full amount of service information and service configuration information is read from the database and written to the shared memory of the host where the service configuration change process is located;

[0023] Read the cache in real time and determine whether there is a change record of service information or service configuration information in the cache. When the judgment result is "yes", read the latest service information or service configuration information from the database and write it to the shared memory of the host where the service configuration change process is located.

[0024] This embodiment includes the following main steps.

[0025] 1) Maintain service information in the graphical interface or command line interface, including adding, modifying, deleting, and querying service information. Service information includes: service ID, service name, version number, scenario, scenario instance, sub-scenario, sub-scenario instance, and manufacturer.

[0026] 2) Maintain service configuration information in the graphical interface or command line interface, including adding, modifying, deleting, and querying service configuration information, where the service configuration information includes: service ID, configuration items, and configuration values.

[0027] 3) The service configuration management process receives maintenance requests from the graphical interface or command line interface and handles them separately:

[0028] If a request is made to add a new service, the service ID will be checked from the database table first to see if it already exists. If so, a failure is returned. Otherwise, a piece of service information will be inserted into the database table. If a request is made to modify a service, the service ID will be checked from the database table first to see if it already exists. If so, the service information in the database table will be modified. Otherwise, a failure is returned. If a request is made to delete a service, the service ID will be checked from the database table first to see if it already exists. If so, the service information in the database table will be deleted. Otherwise, a failure is returned.

[0029] If a request is made to add new service configuration information, the service ID and configuration item will be checked from the database table to see if they already exist. If so, a failure is returned. Otherwise, a new service configuration information will be inserted into the database table. If a request is made to modify service configuration information, the service ID and configuration item will be checked from the database table to see if they already exist. If so, the service configuration information in the database table will be modified. Otherwise, a failure is returned. If a request is made to delete service configuration information, the service ID and configuration item will be checked from the database table to see if they already exist. If so, the service configuration information in the database table will be deleted. Otherwise, a failure is returned.

[0030] For requests to add, modify, or delete service information and service configuration information, the service configuration management process not only operates the database but also writes change records of the service information and service configuration information into the cache.

[0031] 4) The service configuration change process is deployed on each host and is used to write service information and service configuration information into the shared memory of the host.

[0032] When the service configuration change process starts, the full amount of service information and service configuration information is read from the database table and written to the machine shared memory; the service configuration change process reads the cache in real time to determine whether the service information or service configuration information has changed. If there is a change, the database table is read and the latest service information or service configuration information is written to the shared memory.

[0033] 5) Each service queries service configuration information through the service configuration query interface.

[0034] The service configuration query interface queries service information and service configuration information from shared memory, and provides multiple interface forms, including: querying the service information list, querying service information based on service ID, querying the service configuration list based on service ID, querying configuration values based on service ID and configuration items, querying the service information list based on configuration items and configuration values, etc.

[0035] 6) Each service subscribes to service configuration change information through the service configuration change subscription interface.

[0036] The service configuration change subscription interface determines whether the service configuration has changed by querying the service configuration information in shared memory in real time. It provides a separate interface for external users. It requires filling in the service ID and configuration item list and providing a callback function.

[0037] 7) When configuration information changes, the system notifies the services that have subscribed to the information.

[0038] For services that use the service configuration change subscription interface, if the configuration information subscribed by the service changes, the callback function specified by the service will be called.

[0039] The present invention uniformly maintains service information and service configuration information in a service configuration center. Each service queries the service configuration through an interface and subscribes to configuration change information. When a configuration parameter is modified, only one modification is required to achieve synchronous update of all hosts without restarting the service, and there is no problem of unsynchronized configuration files on each host.

[0040] Example 2:

[0042] The service configuration management process is used to respond to maintenance requests for service information or service configuration information (including operations such as adding, modifying, and deleting), maintain service information or service configuration information in the database, and write change records of service information or service configuration information into the cache.

[0043] The service configuration change process is used to read the full amount of service information and service configuration information from the database when it starts, and write it to the shared memory of the host where the service configuration change process is located; it is also used to read the cache in real time and determine whether there is a change record of the service information or service configuration information in the cache. When the judgment result is "yes", the latest service information or service configuration information is read from the database and written to the shared memory of the host where the service configuration change process is located.

[0044] The service configuration query interface is used by each service to query service information and service configuration information from shared memory, including: querying the service information list, querying service information based on service ID, querying the service configuration list based on service ID, querying configuration values based on service ID and configuration items, and querying the service information list based on configuration items and configuration values.

[0045] The service configuration change subscription interface is used by each service to determine whether the service configuration has changed by querying the service configuration information in the shared memory in real time.

[0046] The service configuration management interface is used to maintain service configuration information, including command line interface and graphical interface.

[0047] The service configuration display process is deployed on the graphical gateway machine to provide a background interface for the graphical interface.

[0048] The database is used to store the full amount of service configuration information.

[0049] The cache is used to store service information and service configuration information change information.

[0050] The service configuration query client queries the service configuration information from the shared memory of each host in real time. Each service queries the required configuration information through the service configuration query client.
