Description

Technical Field

[0001] The present invention belongs to the field of intelligent hydropower stations, and in particular relates to an intelligently associated one-stop cockpit integrated control method for hydropower stations. Background Art

[0002] Traditional hydropower station monitoring room management often faces problems such as fragmented information, cumbersome operations, low visualization, and slow emergency response. To address these issues, the industry has begun exploring one-stop control methods and intelligent management and control technologies in recent years.

[0003] 1) Traditional hydropower station monitoring system: Traditional hydropower station monitoring systems typically employ a decentralized approach, with data and video streams processed by separate systems and lacking a unified management platform. These systems primarily monitor various hydropower station parameters in real time, but they are complex to operate and display information in a limited manner.

[0004] Technical means: These systems typically rely on wired network connections and use specialized monitoring software to collect and analyze data. Video and data streams are often managed separately, requiring operators to switch between different systems to obtain comprehensive information.

[0005] Disadvantages: The system suffers from severe information silos, cumbersome operations, and low visibility. In emergencies, the system suffers from slow response times, making it difficult to meet the efficient and safe management needs of modern hydropower stations.

[0006] 2) Web-based hydropower station monitoring solution: With the development of network technology, some hydropower stations have begun to adopt Web-based monitoring solutions, which can be accessed through a browser to achieve remote viewing and control of data.

[0007] Technical means: Data is integrated through web technology, providing a certain degree of centralized management and visual display. Users can log in to the system remotely through a browser to view the real-time operating data of the hydropower station.

[0008] Disadvantages: While web-based solutions improve information accessibility, they still lack one-stop control and intelligent connectivity. The speed and accuracy of these systems in responding to emergencies need to be improved.

[0009] In summary, the shortcomings of the existing technology are: 1) Information dispersion and siloed systems: Traditional hydropower station monitoring systems typically disperse data and video streams across different hardware and software platforms, leading to information fragmentation. This forces operators to switch between different systems to obtain comprehensive operational data, reducing work efficiency.

[0010] 2) Complicated operation: Due to the lack of a unified control platform, monitoring personnel need to manually switch different systems and devices to obtain information. This cumbersome operation process increases the possibility of errors and is not conducive to rapid response.

[0011] 3) Limited visualization: Traditional monitoring rooms typically display only limited information and fail to fully and intuitively reflect the overall operating status of the hydropower station. This limitation affects the efficiency and accuracy of monitoring personnel's decision-making.

[0012] 4) Insufficient emergency response capabilities: In emergency situations, traditional monitoring systems find it difficult to quickly integrate relevant information and resources, resulting in delayed emergency response and increased safety risks. Summary of the Invention

A library of playback request signals, an alarm database, a playback event library, a playback time series library, and a screen switching playback signal library enables precise management and automated control of playback content. Playback trigger levels are defined based on the actual operational needs and business processes of the hydropower station. The system automatically adjusts the playback sequence and screen switching strategy to ensure the timely delivery of critical information. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below with reference to the accompanying drawings and examples: Figure 1 This is the functional topology diagram of the one-stop cockpit system of the present invention; Figure 2 This is the network topology diagram of the tablet controlling the large screen of the present invention; Figure 3 This is a flowchart of the information switching business of the large-screen display of the present invention. DETAILED DESCRIPTION

[0029] The preferred solution is Figures 1 to 3 As shown, an intelligent and associated one-stop cockpit comprehensive management and control method for a hydropower station includes a comprehensive information management method for abnormal handling, a cockpit large-screen information flow switching method, a cockpit large-screen switching page management method and a multi-source data fusion method, so as to realize efficient comprehensive management and control of the hydropower station.

[0030] Method 1: Comprehensive information management method for abnormal handling (1) PC side abnormal handling card configuration 1) A dynamic configuration algorithm is used to manage exception handling cards. For example, when a new exception occurs, the system can automatically adjust the content of the exception handling card based on preset rules and parameters, improving response speed and accuracy.

[0031] During the configuration process, clearly define accident characteristics and handling measures, and associate work tickets and operation tickets with the abnormal handling process. For example, for fire casualties, clearly define accident characteristics as smoke and high temperature, and handling measures include activating the fire extinguishing system and evacuating personnel. Associate the corresponding work tickets and operation tickets with these to ensure a standardized and efficient handling process.

[0032] Actions are configured in blocks, with parameters associated with individual action items. For action cards that require cross-process execution, subsequent processing tasks are linked and matched. For example, in the event of a complete plant power outage, the power restoration measures are divided into multiple blocks, each corresponding to different equipment and operating steps. Parameters such as voltage and current are associated with individual action items. For action cards that require cross-process execution, such as those involving both equipment maintenance and personnel scheduling, subsequent processing tasks are linked and matched to ensure a seamless transition throughout the entire process.

[0033] The configuration information for an abnormality handling card includes four components: accident characteristics, handling measures (including task step configuration, warning parameter configuration, and linking two tickets), precautions configuration, and warning rule configuration. For example, for a power grid accident, accident characteristics may include voltage fluctuations and frequency anomalies. Handling measures include adjusting generator output and switching to backup lines. Task step configuration can be detailed down to the specific sequence and timing of each operation. Warning parameter configuration can set voltage and frequency thresholds. Linking two tickets includes work tickets and operation tickets. Precautions configuration can include safety precautions and operating specifications. Warning rule configuration specifies the circumstances under which an alarm is triggered.

[0034] Abnormal handling templates cover a range of abnormal situations, including power plant operational anomalies such as flooding, complete power outages, fires, power grid incidents, and flood-season natural disasters. These templates, developed based on past experience and actual conditions, provide guidance for rapid response and accurate handling.

[0035] The PC-side exception handling card configuration formula is: Exception Handling Card Relevance = ∑(Work Ticket Relevance × Weight 1 + Operation Ticket Relevance × Weight 2 + Parameter Relevance × Weight 3). For example, assuming the work ticket relevance is 0.8, the operation ticket relevance is 0.7, the parameter relevance is 0.6, Weight 1 is 0.4, Weight 2 is 0.3, and Weight 3 is 0.3, then the exception handling card relevance = 0.8 × 0.4 + 0.7 × 0.3 + 0.6 × 0.3 = 0.32 + 0.21 + 0.18 = 0.71.

[0036] (2) Abnormal handling card activation When monitoring data is abnormal and triggers an alert rule, the cockpit system (including the PC and large screen) automatically pops up an exception handling notification. For example, when the water level monitoring data at a hydropower station exceeds the set threshold, the system automatically triggers the alert rule, and the cockpit system immediately pops up an exception handling notification on the PC and large screen, reminding staff to handle it promptly. The cockpit system's backend service automatically monitors the abnormal handling card alert information. The user clicks to process, sets the device type and block, and automatically generates an abnormal handling task in the abnormal handling task list. The large screen automatically flashes to switch to the abnormal handling task execution progress and content tracking page. For example, after the user clicks the abnormal handling notification on the PC, the system automatically determines the device type and block based on the monitoring data and generates a corresponding task in the abnormal handling task list. At the same time, the large screen automatically flashes to switch to the task execution progress and content tracking page, allowing staff to understand the task's execution status in real time.

[0037] (3) Execution of exception handling tasks 1) On-site execution on the mobile app The task is sent to the executor's mobile device, who then confirms and receives the task. For example, when an exception handling task is generated, the system automatically sends the task to the relevant executor's mobile device, who can then confirm and receive the task through the mobile app.

[0038] During operations, soldiers can use wearable devices or mobile devices to capture, record, store, and transmit audio and video data such as pictures and videos to front-end equipment control. For example, while working on-site, soldiers can use wearable devices or mobile devices to capture audio and video data such as pictures and videos. The collected data can then be recorded, stored, and transmitted to the front-end equipment control center in real time, allowing management personnel to understand the on-site situation in real time.

[0039] Managers can view and track the execution progress and process in real time on PCs and large screens. For example, managers can view the progress and process of exception handling tasks in real time on PCs and large screens, including the location of the executor, operation steps, and on-site conditions, allowing them to adjust strategies and provide support in a timely manner.

[0040] After completing a task, upload the results. After the front-end review is passed, the task window is closed and the next task is executed. For example, after the executor completes a task, upload the results to the system. After the front-end review is passed, the task window is closed and the system automatically enters the execution process of the next task.

[0041] 2) Manual execution on PC The task is sent to the executor's PC, who confirms and receives the task. For example, for tasks that require operation on a PC, the system sends the task to the executor's PC, who confirms and receives the task.

[0042] After completing a task, manually upload the results to the front-end. After the front-end approves them, close the task window and proceed to the next task. For example, after completing a task on a PC, manually upload the results to the system front-end. After approval, close the task window and prepare for the next task.

[0043] 3) Each handling task automatically matches the work ticket and equipment parameters, and the associated information is configured on the exception handling card. Each task displays the executor, two associated tickets, parameter information, execution records, and on-site images. Staff members issue the task and associated tickets separately for each handling task. For example, for each exception handling task, the system automatically matches the corresponding work ticket and equipment parameters and displays the executor, two associated tickets, parameter information, execution records, and on-site images within the task, making it easier for staff to understand the specific details of the task. Staff members can issue tasks and associated tickets separately based on task needs, ensuring a standardized and efficient handling process.

[0044] Method 2: How to switch information flow on the cockpit large screen (1) Large screen video streaming communication method 1) Install a switch between the one-stop cockpit server and the large-screen host to establish a network connection. For example, in the control center of a hydropower station, the one-stop cockpit server and the large-screen host are connected through a switch to ensure network stability and reliability.

[0045] 2) Obtain relevant authentication information (key, secret) from the interface provided by the large-screen host. For example, the system obtains authentication information through the interface provided by the large-screen host to ensure that only authorized users can access the large-screen video stream.

[0046] 3) After verification, the flv or rtmp stream address is returned and stored in the one-stop cockpit server. For example, after verification, the system returns the flv or rtmp stream address and stores it in the one-stop cockpit server for subsequent playback and call.

[0047] 4) Finally, the system displays the video stream synchronously on the left and right screens via web page projection or backend service calls. For example, the system can display the video stream synchronously on the left and right screens of a large screen via web page projection or backend service calls, allowing staff to monitor the operation of the hydropower station in real time.

[0048] (2) Pad controls the large screen page to switch display mode 1) Deploy the cockpit management information system on the Industrial Internet platform as the input source for large-screen page displays. For example, deploy the cockpit management information system on the Industrial Internet platform, obtain various data and information about the hydropower station through the platform, and use this as the input source for large-screen page displays, ensuring the real-time and accuracy of the displayed content.

[0049] 2) The tablet establishes a network connection with the large-screen host via Wi-Fi. If Wi-Fi is unavailable on the tablet, a Bluetooth module can be installed on the large-screen host to connect the tablet to the large-screen host via Bluetooth. For example, in a hydropower station's control center, a tablet can establish a network connection with the large-screen host via Wi-Fi to control and switch between large-screen pages. If Wi-Fi is unavailable on the tablet, a Bluetooth module can be installed on the large-screen host to connect the tablet to the large-screen host via Bluetooth to control and switch between large-screen pages.

[0050] 3) Use the WebSocket communication mechanism to establish a communication connection between the Industrial Internet Platform, the large-screen host client program, and the tablet computer. For example, use the WebSocket communication mechanism to establish a communication connection between the Industrial Internet Platform, the large-screen host client program, and the tablet computer to ensure real-time data transmission and interaction.

[0051] 4) When the tablet triggers the large-screen linkage display command, the tablet establishes a connection with the large-screen host and sends a connection heartbeat and display command information, including information such as the large-screen content and parameters displayed on the left and right screens. For example, when a staff member triggers the large-screen linkage display command on the tablet, the tablet establishes a connection with the large-screen host and sends a connection heartbeat and display command information, including information such as the large-screen content and parameters displayed on the left and right screens, to achieve control and switching of the large-screen pages.

[0052] 5) The client program stores the IP address, port number, and command information, and simultaneously parses the left and right display parameters included in the command information. For example, the client program stores the IP address, port number, and command information sent by a tablet computer, and simultaneously parses the left and right display parameters included in the command information to correctly display the large screen content.

[0053] 6) Call the one-stop cockpit system's large-screen page to display the routing address, use the service to open a browser to distribute the page to the left and right screens, and implement the left and right screen linkage projection function. For example, call the one-stop cockpit system's large-screen page to display the routing address, use the service to open a browser to distribute the page to the left and right screens, and implement the left and right screen linkage projection function, allowing staff to view the hydropower station's operating status in real time.

[0054] (3) Laser pointer and tablet computer Bluetooth connection method The laser pointer connects to the tablet computer via Bluetooth. The tablet computer's control program receives the laser pointer's control commands (pg up and pg dn). Once connected, the large-screen host computer switches to the previous and next screens on the large-screen display. For example, in a hydropower station's control center, workers can use a laser pointer to connect to a tablet computer via Bluetooth. The tablet computer's control program receives the laser pointer's control commands (pg up and pg dn). Once connected, the large-screen host computer switches to the previous and next screens on the large-screen display, allowing workers to quickly view different pages.

[0055] Method 3: Cockpit large screen switching page control method (1) Large screen display area The one-stop cockpit system receiver program is deployed on the large-screen host. The main screen is divided into two sections, the left and right, to connect to the cockpit system data stream. A wireless router is placed under the large-screen host as a relay network. After the tablet is powered on, it connects to the relay wireless network, and the screen switching control buttons are distributed on the tablet. For example, in the control center of a hydropower station, the one-stop cockpit system receiver program is deployed on the large-screen host. The main screen is divided into two sections, the left and right, each displaying different content. A wireless router is placed under the large-screen host as a relay network. After the tablet is powered on, it connects to the relay wireless network to communicate with the large-screen host. The screen switching control buttons are distributed on the tablet, allowing staff to control the large-screen switching and display content using the tablet.

[0056] (2) Pad large screen switching control area 1) In the configuration, enter the access address, display name, and page display name. The page display name should be the title displayed in the browser. Ensure that the program can find the relevant page and save the configuration to support the selection of large-screen support system page display. For example, in the Pad large-screen switching control area, staff can enter the access address, display name, and page display name in the configuration. The page display name should be the title displayed in the browser. Ensure that the program can find the relevant page and save the configuration to support the selection of large-screen support system page display.

[0057] 2) Store the pages opened in the browser on the tablet. Use the tablet to control the pages opened and displayed on the left and right screens. Select the corresponding page to ensure that the program can find the relevant page. Save the configuration to support the selection of the browser system page display. For example, store the pages opened in the browser on the tablet. Use the tablet to control the pages opened and displayed on the left and right screens. Select the corresponding page to ensure that the program can find the relevant page. Save the configuration to support the selection of the browser system page display.

[0058] 3) Basic information displayed on the large screen when no announcement request is received or an exception handling event occurs; that is, the page is displayed under normal circumstances. Switching between different comprehensive basin sub-pages can be done using the pad. For example, under normal circumstances, the large screen displays basic information, including the operating status of the hydropower station and equipment parameters. Switching between different comprehensive basin sub-pages can be done using the pad, making it easier for staff to view the status of different areas.

[0059] 4) When an offline user requests an announcement notification, it submits a screen switching request for the announcement notification function. The user informs the cockpit administrator of the announcement information, urgency, and other information, and sets the announcement time period. After review, the announcement is automatically placed in the playback sequence, awaiting automatic screen switching. When the announcement playback event occurs, the right screen control area is automatically seized for automatic playback, with priority over the comprehensive information large screen display. For example, when an offline user requests an announcement notification, it submits a screen switching request for the announcement notification function, informing the cockpit administrator of the announcement information, urgency, and other information, and setting the announcement time period. After review, the announcement is automatically placed in the playback sequence, awaiting automatic screen switching. When the announcement playback event occurs, the right screen control area is automatically seized for automatic playback, with priority over the comprehensive information large screen display.

[0060] 5) When an emergency occurs and the emergency plan is activated, the system directly connects to the large-screen host and takes over screen playback. Regardless of the content being played on the large-screen, it automatically gives way to the emergency exception handling large-screen content. The left side plays real-time tracking of the emergency response process flow, while the right side calls the video surveillance content of the incident alarm. This takes precedence over the information displayed on the comprehensive information screen and the announcement notification screen. For example, when an emergency occurs and the emergency plan is activated, the system directly connects to the large-screen host and takes over screen playback. Regardless of the content being played on the large-screen, it automatically gives way to the emergency exception handling large-screen content. The left side plays real-time tracking of the emergency response process flow, while the right side calls the video surveillance content of the incident alarm. This takes precedence over the information displayed on the comprehensive information screen and the announcement notification screen.

[0061] Method 4: Multi-source data fusion method (1) Collect data from the hydropower station monitoring system and use a combination of real-time database and historical database to store various types of collected data.

[0062] 1) A real-time database is used for rapid query response, while a historical database is used for long-term storage and data analysis. For example, a real-time database can store a hydropower station's real-time operating data, such as water level, flow, voltage, and current, for rapid query response and real-time monitoring. A historical database can store the hydropower station's historical operating data for long-term storage and data analysis to identify potential issues and trends.

[0063] 2) Clean, integrate, and mine collected data. By defining a unified data model, data from different sources can be mapped into a common data structure. This data can then be fused and integrated to form a unified data view. For example, collected data can be cleaned to remove noise and outliers. Data from various sources, such as hydropower station monitoring systems, meteorological systems, and hydrological systems, can be integrated and mined to uncover potential relationships and patterns. By defining a unified data model, data from various sources can be mapped into a common data structure and fused to form a unified data view, facilitating analysis and decision-making.

[0064] 3) The data view includes a real-time and historical database for comprehensive information management, which is used to manage basic data display, as well as a notice database and an emergency exception database. For example, the data view includes a real-time and historical database for comprehensive information management, which manages the operating and historical data of a hydropower station. It also includes a notice database and an emergency exception database, which are used to manage notice and emergency exception data integration, and to organize types, urgency, and emergency response plans.

[0065] (2) According to the playback time requirements of the comprehensive information screen, announcement notification screen, and emergency event screen, a relationship diagram of playback request signal-data-event-time-screen switching playback signal is established.

[0066] 1. Playback Request Signal Library: This library records screenplay requests initiated by users or the system, including information such as the request source, request content, and priority. For example, the library can record screenplay requests initiated by users or the system, including the request source (e.g., PC, mobile, large screen), request content (e.g., comprehensive information large screen, announcement notification large screen, emergency large screen, etc.), and priority, so that the system can play and switch based on the request priority.

[0067] 2. Alarm Database: This database stores specific data on emergency events and closely interacts with the emergency exception management module. For example, the alarm database can store specific data on emergency events, such as event type, time of occurrence, location, and severity. This closely interacts with the emergency exception management module to ensure that the system can respond and handle emergencies in a timely manner.

[0068] 3. Playback event library: This library integrates various types of event information to be played, including the content of comprehensive information screens, announcement notification screens, and emergency event screens, as well as their corresponding playback sequences. For example, the playback event library can integrate various types of event information to be played, including the content of comprehensive information screens, announcement notification screens, and emergency event screens, as well as their corresponding playback sequences, so that the system can play and switch according to the predetermined playback sequence.

[0069] 4. Playback Time Series Library: This library records the planned and actual playback times of all playback events, which is used to track playback history and optimize playback plans. For example, the playback time series library can record the planned and actual playback times of all playback events, which is used to track playback history and optimize playback plans, allowing the system to better arrange playback order and time.

[0070] 5. Screen switching signal library: This stores screen switching instructions and automatically or manually triggers screen content switching based on event priority and playback schedule. For example, the screen switching signal library can store screen switching instructions and automatically or manually trigger screen content switching based on event priority and playback schedule, so that the system can switch screen content and display relevant information in a timely manner when different events occur.

[0071] (3) Association logic management Based on the actual operational needs and business processes of a hydropower station, playback trigger levels are set, such as general information display, important notification broadcasts, and emergency response. The system automatically adjusts the playback order and screen switching strategy based on the trigger level, ensuring that key information is delivered to decision makers and operators in the shortest possible time. The playback priority formula is: Playback priority = trigger level coefficient × urgency coefficient × time sensitivity coefficient. For example, based on the actual operational needs and business processes of a hydropower station, the playback trigger levels can be set, such as a trigger level coefficient of 1 for general information display, a trigger level coefficient of 2 for important notification broadcasts, and a trigger level coefficient of 3 for emergency response. The urgency coefficient can be set based on the severity of the event, and the time sensitivity coefficient can be set based on the timeliness of the event. Based on the trigger level, urgency coefficient, and time sensitivity coefficient, the system automatically adjusts the playback order and screen switching strategy to ensure that key information is delivered to decision makers and operators in the shortest possible time.
