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 existing D5000 primary standby system is two sets of D5000 systems deployed in different geographical locations, as shown in fig. 1, for example: the national center D5000 main dispatching system is deployed in Beijing, the D5000 standby dispatching system is deployed in Shanghai, and the two systems are in a main-standby relationship. The invention provides a master-slave mode control method based on a D5000 master-slave system, which is characterized in that the method is based on two sets of the existing D5000 master-slave systems, realizes the parallel operation (active-active operation) of the master-slave D5000 double systems, and converts the master-slave system into a master-slave system; the master-slave mode management of the system is supported, the control right of the master and the slave can be switched quickly when needed, and the reliability and the emergency support capability of the D5000 system are improved.
The invention designs a master-slave mode control method based on a D5000 master-slave modulation system, which mainly comprises the following four parts: man-machine master-slave mode control, master-slave mode management, application master-slave control and data master-slave synchronization. Referring to fig. 2, the respective functions will be described in detail.
1. Man-machine master-slave mode control
The man-machine master-slave mode control mainly realizes master-slave mode information display and master-slave mode switching on a man-machine console.
1) Man-machine master-slave mode display
Integrating a system mode display function on a D5000 human-machine console, wherein the system mode comprises a master mode and a slave mode, the console sends a system mode query request to a master-slave control management system when being started, the current system mode is acquired from the master-slave control management system, the current system mode is displayed in a picture mode at the upper left corner of a toolbar of the console, if the current system mode is the master mode, a picture with a 'master' character is displayed, and if the current system mode is the slave mode, a picture with a 'slave' character is displayed and used for prompting a user to currently log in the mode of the system; the left upper corner of the control console toolbar is integrated with a master-slave mode alarm monitoring function, and the master-slave mode alarm monitoring function is used for monitoring master-slave mode abnormal alarm information pushed by a master-slave mode monitoring module in a master-slave mode management system and displaying the master-slave mode abnormal alarm information to a user in real time, if no alarm is given, a green alarm lamp picture is displayed, and if an alarm is given, a red alarm lamp is displayed and is subjected to flicker prompt, so that the user can make a decision to obtain the alarm information in time.
2) Man-machine master-slave mode switching
The man-machine master-slave mode switching interface supports switching of a master-slave mode, one of a D5000 master-slave mode system or a D5000 standby-slave mode system can be switched to the master mode system, the system switched to the master mode has the functions of allowing control instructions to be issued and synchronizing data to the slave mode system, and due to the fact that the master-slave mode switching of the system is particularly important, a dual-user authentication mechanism is adopted, namely two different users respectively input respective user names and passwords, when the two different users pass authority verification, the master-slave mode switching switch (for example, displayed in a button mode) can be operated through the interface, the dual-user authentication mechanism can ensure the safe switching of the system, and the operation safety of a power grid is guaranteed. After the man-machine master-slave mode switching interface operates the master-slave mode switching switch, a master-slave mode storage module in the master-slave mode management system is called, and the switching result is subjected to persistent storage.
2. Master-slave mode management
The master-slave mode control management system is responsible for managing resident services of the master-slave system control functions and ensuring that each application function operates in a master mode under the condition of normal operation. The master-slave mode control management module comprises four functional modules, namely a master-slave mode query module, a master-slave mode monitoring module, a master-slave mode switching module and a master-slave mode storage module.
1) Master-slave mode query module
The master-slave mode query module is a query service provided for the external, and is used for each application to query the master-slave mode state of the D5000 master-slave mode system. In order to conveniently describe two systems of the main standby D5000 system, the invention provides the concepts of a local system and a remote system. The local system and the remote system are relative concepts, and depending on the place where the user accesses the system, if the user accesses the system at the calling place, the D5000 calling system is called as the local system, and the D5000 standby system is called as the remote system; if the user accesses the system at the backup site, the D5000 backup system is called a local system, and the D5000 calling system is called a foreign system.
The principle of master-slave mode query is shown in fig. 3, and the process is shown in fig. 4, and mainly includes:
when receiving the system mode query request, the master-slave mode query module judges whether the current system (the system sending the query currently) is a local system:
if the local system is the master-slave mode query module of the local system, the master-slave mode query module of the local system sends a master-slave mode query request to a resource positioning service, the resource positioning service positions a real-time data operation service (supporting the operations of creating, deleting, updating and querying real-time library data) and sends the master-slave mode query request to the service, the real-time data operation service acquires the master-slave mode data of the local system from a real-time library and then returns the master-slave mode data step by step, and finally the master-slave mode data is returned to a query requester;
if the remote system is used, because the D5000 main and standby debugging systems cannot be directly connected for data interaction, and the data interaction is carried out through the connection of the proxy services of the respective systems, if the master-slave mode of the remote system is to be acquired, firstly, a master-slave mode query module of a local system needs to send a master-slave mode query request to the proxy service of the current system, then, the proxy service of the current system sends the master-slave mode query request to the proxy service of the remote system, then, the remote proxy service sends the master-slave mode query request to the real-time data operation service of the remote system, the real-time data operation service acquires the master-slave mode data of the remote system and then returns the master-slave mode data step by step, and finally, the master-slave mode data is returned to a query requester.
2) Master-slave mode monitoring module
The master-slave mode monitoring module is used for monitoring the master-slave mode of the D5000 master-slave mode system, under the normal operation condition, only one system operates in the master mode, and the alarm prompt is carried out in the abnormal state (such as the master-slave mode and the master-slave mode), so that the application of working personnel for timely processing the master-slave mode abnormality is facilitated.
As shown in fig. 5, the master-slave mode monitoring process mainly includes:
the master-slave mode monitoring module acquires master-slave modes of a local system and a remote system by calling the master-slave mode query module, judges the master-slave modes of the two systems, constructs an alarm message and generates an alarm if the two systems are double masters/double slaves, and pushes the alarm to a human-computer console for display; otherwise, the next round of monitoring is entered.
3) Master-slave mode memory module
The master-slave mode has great influence on the system control instruction issuing and data synchronization direction, so the master-slave mode is encrypted and then persistently stored in a real-time library of a local/remote system.
The master-slave mode storage process is generally consistent with the master-slave mode query process, and the main difference is that after a master-slave mode management system receives a master-slave switching storage request of a human machine, plaintext data such as a system name, a system master-slave mode (for example, 1 represents the master mode; and 0 represents the slave mode), an update date and the like are obtained from a human machine console, ciphertext data are generated according to a self-encryption algorithm and are simultaneously stored in a real-time library of a local/remote system, and the ciphertext storage is used for ensuring that the master-slave mode of the system cannot be influenced even if a user modifies the master-slave mode of the system by using a real-time library modification tool.
Because the master-slave mode of the ciphertext storage system is realized, encrypted data is a string of irregular character strings, after the ciphertext character strings are manually modified, an expected result (1 or 0) cannot be obtained after the ciphertext is analyzed by applying a decryption algorithm, so that the system can timely push an alarm to prompt a user that the master-slave mode state of the system is manually modified, the system operation cannot be influenced, and the aim of storing the ciphertext is to add one layer of safety protection to the system.
4) Master-slave mode switching module
The master-slave mode switching module is responsible for switching master-slave working modes of the D5000 master-slave debugging system and can perform manual switching as required. Before switching, the related authority information needs to be confirmed, and the user with authority can carry out switching operation. The switching process ensures consistency, namely, the switching of the master mode and the slave mode of the D5000 master-slave debugging system is successful or fails. After switching, the master-slave mode of the system is stored in the master-slave mode information table of the real-time library for subsequent query.
Because the master-slave operation mode between the systems is important and can influence the master-slave response of the application function, when the master-slave mode is abnormal, the automatic master-slave mode switching is not carried out, the abnormal alarm is carried out, the master-slave abnormal is prompted to a worker, and the abnormal needs to be repaired manually or the master-slave mode switching is carried out manually.
3. Using master-slave control
The master-slave control is applied to realize that the control operation is allowed to be issued only under the master mode system, and the slave mode is forbidden to send, because the control operation misoperation has large influence on the operation of the power grid, the control instruction is ensured to be allowed to be issued only under the master mode system and is forbidden to be issued under the slave mode system through the three-layer control of the right-key menu master-slave control, the control application master-slave control and the front master-slave control.
Referring to fig. 6, a process of applying master-slave control specifically includes:
1) right key menu item master slave control
The man-machine browser can be opened through a menu item of the man-machine console, the man-machine browser not only shows the real-time working condition of the plant station for a controller, but also provides a right-key menu for the controller to perform control operation, and the controller is supported to perform control operation on the plant station on a browser picture as follows: remote control, remote regulation and other control operations. The method comprises the steps that a right-key menu of a control application is subjected to display and hidden control according to a master-slave mode of a system, when equipment is selected on a man-machine browser to perform right-key operation, whether a control operation menu item is displayed or not is judged through a master-slave mode query function, and if the current system is in the master mode, the control operation menu item is displayed; hiding the menu item of the control class operation if the current system is slave mode.
2) Control class applies master-slave control
The control application mainly comprises SCADA, AGC, AVC and FES applications, in order to ensure the safety of service control of the control application, mutual exclusion verification is carried out on the master-slave mode of a system to which the control application belongs, a master-slave mode identifier of the system is obtained through a master-slave mode query function, only one system of a plurality of systems is used as the master mode at the same time, the rest systems are used as slave modes, if the current system is the master mode, the control application allows the control command to be issued, and if the current system is the slave mode, the control application prohibits the control command from being sent.
3) Front-end application master-slave control
When the preposed application receives remote control, gear adjustment and point setting control commands in the system, a system principal and subordinate mode identification is obtained through a principal and subordinate mode query function and is used for judging whether the control commands are issued to a corresponding station or not, principal and subordinate mode checking is carried out before the remote control, gear adjustment and point setting commands are issued, when the system is in a principal mode, the preposed application allows control type commands to be issued to the station, when the system is in a subordinate mode, the preposed application forbids the control type commands to be issued to the station, the preposed application controllable identification inherits the principal and subordinate mode of the system and is only controllable by a main system, consistency of controllable identifications of the principal and subordinate systems is guaranteed through an inter-system synchronization mechanism, and only one preposed system can issue the control commands to the corresponding station at the same time.
4. Data master-slave synchronization
When data of the master mode system changes, the changed data needs to be synchronized to the slave mode system, data synchronization is carried out on each application data from the master mode system to the slave mode system, before data synchronization is carried out on a model, a file, a front-end, a manual operation and other data synchronization services, a master-slave mode identifier of a current system is obtained through master-slave mode inquiry, if the current system is in the master mode, the data synchronization service carries out operation of synchronizing the data of the system to the slave mode system, and if not, any synchronization operation is carried out.
The invention relates to a master-slave mode control method based on a D5000 master-slave system, which is characterized in that master-slave mode control supports parallel operation of the master-slave system, two sets of systems in parallel operation do not distinguish master-slave relation, only have the concept of master-slave system, the two sets of systems are peer-to-peer systems, any system can be used as a master system, and the master-slave mode switching of the system is carried out at any time after authority verification; the master-slave mode uses a ciphertext mode to be durably stored in a real-time library; the master-slave mode management is a core function of master-slave mode control, supports master-slave mode query, master-slave mode storage, master-slave mode exception alarm and the like, and directly controls the issuing of a preposed and applied control command and the synchronization of various data.
