Description

Technical Field

[0001] The present invention belongs to the field of large power grid safety and stability control equipment products, and specifically relates to a method and device for displaying massive load data based on menu-based dynamic configuration. Background Art

[0002] At present, in the power system secondary relay protection and safety automatic equipment industry, combined with Figure 1 , it has not yet been possible to display different types of data objects such as global data and global status in the same menu interface. Generally, the current level menu either displays global data or global Boolean status.

[0003] Among them, the device interface menu display mechanism is to protect the CPU to set the display group of the global data that needs to be displayed in the interface menu, and associate the telemetry communication type in the communication protocol configuration table, set the display group of the global status, and set the communication elements such as message type, information sequence number, function type, etc. in the communication protocol configuration table for the protection CPU to send messages to the interface CPU, and associate the telemeter communication type. The device protection CPU will set the values ​​of the data types such as global data and global status of the communication protocol to the interface CPU, and the interface CPU will display them in the corresponding menu according to the display group set in the interface program.

[0004] For precise load control system equipment, the substation device needs to be connected to at least 200 load shedding terminals. Each terminal needs to display a lot of global data and global status. If the global data and global status of a terminal are displayed in different menus, it is not convenient for debugging and operation and maintenance personnel to browse and view. Therefore, it is necessary to set menus based on terminals, and display different types of data information such as the global data and global Boolean status of the terminal in the same menu interface, and the displayed data content can be flexibly configured according to actual project needs.

[0005] The menu display mode of the conventional precise load control substation device for the received terminal status information (Boolean type), power data information (floating point data type), and fixed value information is as follows:

[0006] Based on the above menu, there are three problems:

[0007] 1) Based on the above menus, the information of a single terminal is scattered in different menu displays. When a large number of precision control substation devices need to be connected, it is difficult to effectively browse and view the data and status information of a single terminal;

[0008] 2) The total abnormal status of each terminal is scattered in the "Abnormal Status" menu, which is not convenient to view;

[0009] 3) The precision control substation device is used in different projects, and the number of access terminals is different. In addition, the terminal data and status information that users need to display in different projects may also be different. Based on the fixed menu display, the terminal display information cannot be flexibly configured, which reduces the versatility of the precision control substation device software and is not conducive to the later maintenance of the product software. Summary of the invention

[0010] In view of the problem that the amount of data information that needs to be displayed by the device is large and the global data and global status cannot be displayed to the user at the same time with the terminal as the object, the present invention provides a method and device for displaying massive load data based on menu dynamic configuration, which optimizes the efficiency of the interface to call the CPU global data and reduces the communication pressure between the interface and the CPU plug-in.

[0011] To achieve the above object, the present invention provides a device for displaying massive load data based on menu dynamic configuration, comprising: a protection CPU plug-in and a human-machine interface CPU; the protection CPU plug-in communicates with the human-machine interface CPU plug-in to send the menu data to be displayed to the interface CPU;

[0012] The human-machine interface CPU plug-in sets the display group according to the menu that needs to be displayed sent by the protection CPU plug-in; the dynamic configuration file downloaded from the human-machine interface CPU plug-in displays the global data and global status information in the corresponding display group according to the established rules to form a subordinate menu of the display group.

[0013] Furthermore, it also includes a communication module, and the protection CPU plug-in obtains the data that needs to be filled in the menu through the communication module.

[0014] Furthermore, the protection CPU plug-in loads the established data model, and exports the data model online through the configuration tool to form a model file, which specifically includes: the target program of the application software generating the data model is downloaded to the protection CPU plug-in and restarted, the configuration tool and the protection CPU plug-in establish an Ethernet communication link through the default IP address, all the information of the data model is queried through the configuration tool, and then the entire data model is exported to form a model file.

[0015] Furthermore, the data model includes a first-level menu, a second-level menu, a third-level menu and an ultimate menu; the first-level menu is an operation type menu, the second-level menu is a display group, the third-level menu is an abnormal state of each terminal, and the ultimate menu is the data of each device terminal.

[0016] The global data that needs to be displayed in the menu of the human-machine interface CPU plug-in are set to display groups; when the human-machine interface CPU plug-in displays the menu, only the global data that needs to be displayed in the currently viewed menu is retrieved from the protection CPU plug-in, and for the global status information, since one bit corresponds to one global status and the amount of data is relatively small, all the global status information is retrieved each time.

[0017] Furthermore, the configuration of global data and global status includes the configuration of various data index numbers and names; the index numbers starting with R are global data index numbers, and the index numbers starting with S are global status data index numbers.

[0018] Furthermore, the established rules include: the left side of the "=" sign is global status information, which is status information displayed on the third-level menu, communication parameters are set in the protection CPU plug-in, and display groups; the content on the left side of the "=" sign is data information belonging to the global status on the right, which is displayed in the corresponding ultimate menu, and is a combination of global data and global status configuration. Communication parameters are set in the CPU, communication protocols are associated, and display groups are set; for the data information of the CPU protection, for global data, global Boolean status and other types of constants that have set communication protocols and display groups, the global status or global data on the left side of the "=" sign is configured in the configuration file to constitute the belonging relationship, which is displayed in the ultimate menu.

[0019] The dynamic configuration method of the dynamic configuration device for displaying massive data information of the load control device comprises the following steps:

[0020] (1) Protect the CPU to set display groups for global data and Boolean state-related communication protocols that need to be displayed in the menu and establish a data model;

[0021] (2) The protection CPU plug-in of the dynamic configuration device for displaying massive data information of the load control device loads the data model, the configuration tool connects to the dynamic configuration device for displaying massive data information of the load control device, and online exports the data file of the dynamic configuration device for displaying massive data information of the load control device to obtain the model file, wherein the model file includes the global data, Boolean state data information and the corresponding quick index number required for menu display;

[0022] (3) Based on the exported data model file, the global data and global status are configured according to user requirements through the configuration tool, and a menu display configuration file is generated through the configuration tool. The global status in the third-level menu and the global status and global data of the ultimate menu are respectively on both sides of the "=" in the generated menu configuration file, forming a subordinate relationship;

[0023] (4) After downloading the menu display configuration file to the path folder specified by the human-machine interface CPU of the load control equipment mass data information display device, restart the human-machine interface CPU; during the power-on and restart process, the human-machine interface CPU parses the display configuration file to obtain the data model to be displayed in the display configuration file;

[0024] (5) The protection CPU plug-in obtains real-time data corresponding to the data model in real time, and the human-machine interface obtains the real-time data that needs to be displayed in real time from the protection CPU plug-in, and displays it in real time according to the configured data model.

[0025] Furthermore, generating a display configuration file through the configuration tool includes: the target program of the application software generating the data model is downloaded to the protection CPU plug-in and restarted, the configuration tool and the protection CPU plug-in establish an Ethernet communication link through the default IP address, querying all the information of the data model through the configuration tool, and then exporting the entire data model to form a model file.

[0026] Furthermore, the global status or global data is displayed on the left side of the "=" sign in the display configuration file, and is displayed in any level menu of the interface according to the set display group, and has an affiliation relationship with the ultimate menu generated by the data configured on the right side of the "=" sign.

[0027] Furthermore, the configuration of global data includes the configuration of various data index numbers and names; the index numbers starting with R are global data index numbers, and the index numbers starting with S are global status data index numbers.

[0028] The above technical solution of the present invention has the following beneficial technical effects:

[0029] (1) The method of the present invention is based on the existing data model file of the current embedded device protection CPU. Through the configuration tool, it can be flexibly configured according to user needs to solve the problem that the current embedded device interface menu cannot intuitively and centrally display all the data information of the current terminal. It also solves the problem that the current embedded device menu cannot display global data and global status information on the same interface at the same time. At the same time, by setting display groups for a large amount of global data, the efficiency of the interface in retrieving CPU global data is optimized and the communication pressure between the interface and the CPU plug-in is reduced.

[0030] (2) The present invention adopts a configuration tool to dynamically associate the model files that need to display data, and then parses the device interface on power-on, thereby providing a convenient, flexible and reliable method for large power grid system protection equipment to display massive data information.

[0031] (3) Generally, when an embedded device displays "Terminal*Abnormal Status", it is the ultimate menu. In order to facilitate users to directly view the global data and global status of the corresponding terminal without going through complicated menu switching operations, the present invention uses a configuration tool to associate the load capacity and global abnormal data model ID of each terminal that needs to be displayed with the abnormal status ID of the terminal through tool configuration, and places the configuration file in the folder specified by the device interface plug-in for power-on analysis.

[0032] (4) Since the application software groups the global data model when creating it, when viewing the device interface menu, only the data group that needs to be viewed is retrieved, preventing the interface from simultaneously retrieving all display data from the CPU plug-in and occupying the backplane Ethernet communication link for a long time.

[0039] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0040] On one hand, the present invention provides a device for displaying massive load data based on menu dynamic configuration, the hardware structure is as follows Figure 1 As shown, it includes: a protection CPU plug-in, a human-machine interface CPU and a communication module.

[0041] The protection CPU plug-in is mainly responsible for the precise load shedding control function and the communication function with other devices in the precise load control system. It is similar to the communication with the human-machine interface CPU plug-in, and sends the menu data to be displayed to the interface CPU. The human-machine interface CPU plug-in receives the data information sent by the protection CPU through the communication module in the interface CPU plug-in according to the device menu design program, and displays it in the corresponding menu according to the display grouping set by the protection CPU and the interface display dynamic configuration file downloaded in the interface CPU plug-in. The menu data displayed by the human-machine interface CPU are all sent by the protection CPU and received by the communication gateway module in the interface plug-in. The menu display structure is determined by two parts. The first part is based on the display grouping set by the protection CPU for the sent interface data, which is not reflected in the interface menu dynamic configuration file. This part is a fixed display; the second part is based on the dynamic display configuration file downloaded to the specified path folder of the human-machine interface CPU. The corresponding data is displayed in the corresponding menu according to the established rules. This part supports flexible configuration according to the actual needs of the project, and is also the core implementation technology of this patent invention.

[0042] The mechanism for the protection CPU to send data to the human-machine interface CPU is detailed in the "Technical Issues" at the end of the document. The human-machine interface loads the display configuration file and the menu display rules are as follows: the display format of the configuration file, the left side of the "=" sign is the global status, this part needs to set the communication parameters in the protection CPU, and display the group; the right side is the global data and global status configuration combination displayed in the same ultimate menu, this part needs to set the communication parameters in the protection CPU, associate the communication protocol, and set the display group. Figure 3 For example, the status on the left is the terminal*abnormal overall status, which is displayed in the three-level menu, and the status on the right is the level*cuttable quantity and abnormal* status, which is displayed in the ultimate menu and has an affiliation with the three-level menu.

[0043] The communication module accesses various types of cuttable loads sent by at least 200 terminals through the communication expansion plug-in, and transmits the data to the protection CPU plug-in via the backplane Ethernet. The protection CPU plug-in completes data processing and logic control, and completes the creation of the data model, which is called when the human-machine interface menu is displayed. The process of the method for displaying massive data information of precise load control equipment based on dynamic configuration is as follows Figure 3 The specific implementation process is as follows:

[0044] (1) Protect the CPU and set display groups for global data and Boolean state-related communication protocols that need to be displayed in the menu, and establish a data model.

[0045] After maximizing data modeling of global data and Boolean states, the application software supports users to organize menu display content according to the actual construction conditions of specific projects without affecting the functional configuration and reliability of the device.

[0046] (2) The protection CPU plug-in of the dynamic configuration device for displaying massive data information of the load control equipment loads the data model, the configuration tool connects to the device, and exports the data file of the device online. The model file contains global data, Boolean status data information and corresponding quick index numbers that need to be displayed in the menu.

[0047] After the target program generated by the application software is downloaded to the device and restarted, the configuration tool and the device establish an Ethernet communication link through the default IP address, query all data model information, and export the entire data model file of the device; the device data model file generated by the configuration tool is in *.xml format. The configuration tool exports the data model file based on the device and displays data configuration according to user needs. The configuration interface of the configuration tool is as follows: Figure 5 shown.

[0048] (3) Based on the exported data model file, the configuration tool is used to configure the global data and global status according to user needs, and a menu display configuration file is generated by the configuration tool. The configuration content is for the data information in the third-level menu and the corresponding ultimate menu. The global status in the third-level menu and the global status and global data of the ultimate menu are respectively on both sides of the "=" in the generated menu configuration file, forming a subordinate relationship, such as Figure 6 As shown in the second line of the file, the three-level menu display status "Terminal 1_Comprehensive Abnormality" above the example on the right side of the figure is subordinate to the data below such as "Terminal 1 Category 1 Cuttable Quantity" and "Terminal 1_Receiving Address Error".

[0049] After the data model file of the device is exported online, the configuration tool is supported to perform offline configuration based on the model file and generate a menu display configuration file; the generated menu display configuration file format is *.txt format. After the display data configuration is completed using the configuration tool, the content of the exported interface display configuration file is as follows: The index number starting with R is the global data index number, and the index number starting with S is the global status data index number. Figure 3 The configuration file CRC is automatically generated by the configuration tool when the display file is exported. Manual modification of the configuration file will cause data errors in the device interface menu display.

[0050] (4) After downloading the display configuration file to the specified path folder of the human-machine interface CPU of the load control equipment mass data information display device, restart the human-machine interface CPU; during the power-on and restart process, the human-machine interface CPU parses the display configuration file and obtains the data model to be displayed in the display configuration file. The wiring menu display effect is as follows Figure 3 If you find that the interface menu displays errors or is incomplete, you can import the display configuration file into the configuration tool, adjust or add or delete it, and regenerate the display configuration file.

[0051] (5) The protection CPU plug-in obtains real-time data corresponding to the data model in real time, and the human-machine interface obtains the real-time data that needs to be displayed in real time from the protection CPU plug-in according to the data ID that needs to be displayed, and displays it in real time according to the configured data model.

[0052] When powered on, the menu display configuration file in the specified path folder of the protection CPU plug-in is loaded and parsed to obtain the data model information required for the menu display, and the real-time data value corresponding to the data model is retrieved from the protection CPU plug-in through Ethernet communication, and displayed in the device human-machine interface menu.

[0053] The global data settings that need to be displayed in the interface menu are grouped. When the menu is displayed, the protection CPU plug-in only retrieves the real-time value of the global data in the currently viewed menu from the protection CPU, which reduces the pressure on Ethernet communication between the interface plug-in and the protection CPU plug-in and improves the real-time performance of data display.

[0054] The configuration tool supports the display of third-level menu data when the second-level menu configured based on the model file can display the global Boolean state value in real time; the third-level menu display content belonging to any global state in the second-level menu not only includes global data information, but also can display the global Boolean state information simultaneously in the same interface; there is a logical relationship between the value of any global state belonging to the second-level menu and the corresponding third-level menu display global Boolean state information, that is, the third-level menu displays the global Boolean state "or" logic triggers the corresponding global state in the second-level menu, which has the advantages of layered and step-by-step display of data information.

[0055] The implementation effect is most obvious when there are many device access intervals or terminals, generally 100 or more, and each terminal needs to display a large amount of global data information and global status information.

[0056] The present invention provides a massive data information display of a precise load control device based on dynamic configuration, which is applied to a precise load control substation for large power grid system protection.

[0057] The device for displaying mass data information of precise load control equipment based on dynamic configuration of the present invention comprises an access interface CPU plug-in, a protection CPU plug-in and a communication plug-in. The communication plug-in is mainly used to access a large number of terminals and receive the load that can be cut at each level sent by each terminal. The protection CPU plug-in is the core processing unit of the device, which completes the logic processing and sends the data status to be displayed to the interface plug-in. The interface MMI plug-in is mainly responsible for communicating with the external monitoring background, displaying the interface menu, and responding to the panel key operation and other functions.

[0058] In the configuration file, "=" indicates the subordinate relationship between the third-level menu and the ultimate menu. The left side is the total abnormal status of the terminal, corresponding to the Figure 1 The middle three-level menu, on the right is Figure 1 In the ultimate menu, the data starting with "R" are global data, and the data starting with "S" are global Boolean states. The configuration file display content and information correspondence are shown in 5 and 6 below. Figure 6 The left side of the "=" sign is the global status, and the right side is the global data and global status configuration combination displayed in the same ultimate menu. Figure 4 For example, the status on the left is the terminal*abnormal total status, and the status on the right is the level*cuttable quantity and abnormal*status.

[0059] In summary, the present invention relates to a method and device for displaying massive load data based on menu-based dynamic configuration, establishing a data model, and exporting the generated model file online through a configuration tool; further configuring, generating a display configuration file, loading the display configuration file during the power-on restart process, and obtaining the data model; the human-machine interface obtains the real-time data that needs to be displayed in real time from the protection CPU plug-in, and displays it in real time. The present invention is based on the existing data model file of the current embedded device protection CPU. Through the flexible configuration of the configuration tool according to user needs, the interface menu can intuitively and centrally display all data information of the current terminal, solving the problem that the current embedded device menu cannot display global data and global status information on the same interface at the same time. At the same time, by setting display groups for a large amount of global data, the efficiency of the interface in retrieving CPU global data is optimized and the communication pressure between the interface and the CPU plug-in is reduced.
