Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The first embodiment is as follows:
as shown in fig. 1, the present invention provides a service-oriented integrated monitoring system supporting active/standby switching, which includes a state server module, a topology calculation service module, a message bus module, a state service client module and a picture client module, where the state server module and the topology calculation service module are deployed on a server, the state service client module and the picture client module are deployed on a workstation, and the message bus module is deployed on the server and the workstation at the same time; the state server module and the message bus module in the server are in communication connection with the topology calculation service module, and the state service client module and the message bus module in the workstation are in communication connection with the picture client module; the workstation is in communication connection with the servers through the message bus module, and the servers are in communication connection through the state server module.
(1) The state service module is used for being responsible for the collection management and the whole-network release of various kinds of running state information of the comprehensive monitoring system; the state service module also supports a configurable conflict detection arbitration and task fault tolerance mechanism in the whole network and the cluster; the state service module provides an open and unified state information registration, read-write updating and subscription publishing interface, supports various programming calling modes such as API, IPC and Web service, and is flexibly used by other application software modules.
(2) The topology calculation service module is used for acquiring the state information from the state service module through the message bus module and carrying out analysis and calculation; the topology calculation service module sets a main and standby working mode according to the fault-tolerant arbitration result of the state service module, and the topology calculation service module in the main working mode externally releases the calculation result; and the topology calculation service module provides services such as power supply point result query, electrical equipment live state query, power supply path query and the like for the outside uniformly through the message bus module. The topology calculation service module supports a master-slave fault-tolerant mechanism, reads and writes state information and subscription state notification through information interaction with the state service module, sets a master-slave working mode according to a fault-tolerant arbitration result of the state service, and externally releases a calculation result by a topology host (namely the topology calculation service module in the master working mode).
(3) The state service client module is used for acquiring the main and standby working modes of the topology calculation service module and issuing the working modes to the picture client module; the picture client module obtains the calculation result from the topology calculation service module in the main working mode through the message bus module and displays the picture, and the data source consistency obtained by each node can be ensured by obtaining the calculation result from the topology calculation service module in the main working mode, so that the data synchronization pressure caused by the fact that the calculation result is stored in a real-time library is reduced. When the picture client subscribes the required data to the message bus module, the registration to a plurality of servers is supported at one time, the source of the data can be effectively distinguished by acquiring the topology host information from the state service client module, the influence of network abnormity on the monitoring of the system picture is reduced, and meanwhile, when the topology host information is changed, the process of accessing the server data by the picture client can realize the non-inductive switching.
Example two:
based on the service integrated monitoring system supporting the master-slave switching provided in the first embodiment, in order to reduce the synchronization pressure of a real-time library and ensure the consistency of the topology calculation data source obtained by the picture client under the layered and distributed high-capacity system architecture, the original topology calculation program is subjected to service transformation by adopting the design idea of modularization and service-oriented, and the calculation result of the server is subjected to data distribution through the message bus module; a topology calculation analysis servitization method is provided, which comprises the following steps:
2.1, predefining a public calling header file of a message bus module, determining input and output parameters, and generating a dynamic library file;
2.2, a dynamic library file is quoted in a picture client module and a topological computing service module code project pro file;
2.3, registering topology calculation data required by subscription to the message bus module through the picture client module;
2.4, reading required real-time data from a real-time library through a topology calculation service module, analyzing the topological structure of the electric network based on the breadth-first search algorithm of the adjacent matrix, and generating a calculation result;
2.5, calling a monitoring interface of the message bus module through the topology calculation service module, and calling a data publishing interface to distribute a calculation result when a notification that the picture client subscribes for registration is available;
and 2.6, obtaining a calculation result from the message bus module through the picture client and displaying a picture.
Example three:
based on the service-oriented integrated monitoring system supporting the primary/standby switching provided in the first embodiment, in order to ensure stable operation of the integrated monitoring system platform, it is a key point to be comprehensively considered how to effectively and accurately arbitrate the primary/standby application programs by using a primary/standby fault-tolerant mechanism, and whether the standby operation program has an ability to immediately start external restoration services when the primary operation program exits abnormally. The topology calculation service program supports a master-slave deployment operation mode; a topology service active/standby switching method is provided, which comprises the following steps:
3.1, registering key name information of the registered main and standby working modes to a state service module through a topology calculation service module, and subscribing key names;
3.2, processing the change of the main and standby working modes of the topology calculation service module based on the callback function of the key name, and processing the flag bit of the main and standby working modes;
the process of calling the function B in other functions a by means of a function B pointer (the source of the B function pointer can be obtained by, but is not limited to, parameter passing) is called a callback, and the called B function is called a callback function of a.
When key name information of a topology host state is registered to the state service module, one item of function interface parameters provided by the state service module needs to be transferred to a callback function address, the callback function address defined by the application module is transferred to the state service module in a parameter transfer mode, then the state service module calls the callback function of the key name through a transferred function pointer when a certain condition is met, and a user processes the information of the primary and standby working modes of the topology in the callback function.
As shown in fig. 2, when the topology service program runs on machines sac1, sac2, and sac3, one and only one machine is a main running machine providing services, for example, sac1 is a main machine, the remaining machines sac2 and sac3 are standby machines, and the election of the main/standby states is completed by the state service module. And the state service module informs the picture client module of the main and standby working modes of the topology calculation service module through the registered callback function. The state service module serves as a communication bridge between the topology calculation service module and the picture client module. In the customized callback function, the state service module informs the key value of the key name of the currently subscribed message, so that the screen client can know that the current sac1 machine is the running main node. Then, a string-type variable is used as a flag in the user program to record information of a host node (i.e., a host of the topology) currently providing the topology calculation service module, and the frame client should perform network communication with the host when connecting. If the host is switched in the callback function, if the host is already switched to sac2, the client should be switched to sac2 in time, otherwise, when sac1 is still connected, the screen client cannot acquire the calculation data of the required server because sac1 becomes the standby computer and no longer provides the service data of topology calculation.
3.3, when a plurality of servers are all provided with a topology calculation service module, arbitrating and selecting a main/standby working mode through a state service module, and releasing the main/standby working mode through the whole network;
as shown in fig. 2, when only the sac1 machine runs the topology program, the state service module arbitrates the sac1 machine as the topology master. When the sac2 machine starts the topology program, the sac2 machine is the topology standby machine.
When the host operation topology program exits and cannot provide the service due to the fact that accidental power failure occurs to the sac1 server, the state service module conducts arbitration, and the sac2 is elected as a host operation node of the topology. When the main and standby program operating modes are switched, the state service module will notify the application program of the message through the callback function to perform corresponding processing.
When the sac1 machine is powered back and the topology program is started, the sac1 and the sac2 both run the topology program, and the sac2 is the host at present. According to different configuration strategies, if sac1 is configured to have a high priority, after the sac1 topology program is started, the state service switches the topology host from sac2 to sac1 at the moment, and sac1 is the main sac for standby. If the configured policy is first come first get mode, then since sac2 is already the host, the time priority of the topology program started by sac1 is low, and then sac1 is standby and sac2 still keeps the host unchanged.
3.4, when the topology calculation service module receives callback information corresponding to the registered key name, updating the main/standby working mode and the main/standby display flag bit;
and 3.5, if the updating result is in the main working mode, the topology calculation service module normally performs topology analysis calculation, and if the updating result is in the standby working mode, the topology calculation service module enters a dormant state.
In a fourth aspect, based on the service-oriented integrated monitoring system supporting active/standby switching provided in the first embodiment, for a situation of machine and service deployment in a layered distributed architecture, topology services can be run in both the active/standby center and each sub-domain, and an architecture diagram is shown in fig. 2. The topology service carries out intra-domain fault-tolerant processing through the state service module, supports the state message distribution of the whole network universe, and has flexible and configurable connection priority between the picture client and the host; the embodiment provides a method for switching data of a picture client accessing a topology host based on the service-based integrated monitoring system, which comprises the following steps:
4.1, the picture client subscribes the key name of the topology calculation service module of the main working mode of the local domain and the central domain, and processes the main and standby working modes based on the callback mechanism of the state service module;
4.2, reading the connection priority configuration information of the picture client, and determining information used by the picture client based on the connection priority configuration information;
4.3, the picture client subscribes a calculation result of the topology calculation service module of the main working mode through the message bus module;
4.4, the picture client accesses the calculation result issued by the topology calculation service module corresponding to the main working mode according to the used information;
and 4.5, if the main and standby working modes of the topology calculation service module change, returning information for determining the use of the picture client based on the connection priority configuration information.
Wherein determining information used by the screen client based on the connection priority configuration information comprises:
the picture client in the central domain only reads and uses the information of the topology calculation service module of the main working mode in the central domain;
the information read and used by the picture client in the subdomain meets the following requirements:
when the topology calculation service module is configured to be preferentially connected with the topology calculation service module of the main working mode of the central domain, if the information of the topology calculation service modules of the main working modes of the central domain and the subdomains can be obtained, the information of the topology calculation service module of the main working mode of the central domain is used; if the information of the topology calculation service module of the main working mode of the central domain or the sub-domain can only be obtained, the information of the topology calculation service module of the main working mode of the corresponding central domain or the sub-domain is used;
when the topology calculation service module is configured to be preferentially connected with the main working mode of the subdomain, if the information of the topology calculation service modules of the central domain and the main working mode of the subdomain can be obtained, the information of the topology calculation service module of the main working mode of the subdomain is used; and if the information of the topology calculation service module of the main working mode of the central domain or the sub-domain can be obtained only, using the information of the topology calculation service module of the main working mode of the corresponding central domain or the sub-domain.
