Description

Technical Field

[0001] The invention belongs to the technical field of hydropower station dam safety and relates to a hydropower station dam break early warning system. Background Art

[0002] As an important water conservancy project facility, hydropower station dams face risks such as floods, geological disasters, and structural problems. Dam breach incidents show that dam breach accidents may cause serious and unacceptable casualties and property losses. The existing technical solution is to use personnel to analyze and verify various data collected from the dam, and to communicate one-to-one by making phone calls when it is determined that the dam structure has obvious abnormalities or a dam breach has occurred. The implementation cost of some existing technical solutions is high, which limits their popularity in large-scale applications, especially for small and medium-sized hydropower stations.

[0003] Existing dam safety monitoring methods mainly rely on manual patrols and regular inspections. This method has limitations and cannot monitor and warn the dam structure in real time. At the same time, the current hydropower station dam break warning system lacks unified standards and specifications, resulting in differences between local systems, which is not conducive to information sharing and the rapid transmission of warning signals. Residents living near hydropower stations do not understand the consequences of dam break and emergency evacuation plans, and cannot correctly choose escape routes. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a hydropower station dam breach early warning system, which can promptly transmit the early warning system to hydropower station staff and nearby community personnel, so as to achieve the purpose of emergency evacuation and risk avoidance in the first time, and improve the rapid emergency response capability of personnel after a hydropower station dam breach occurs.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a dam break early warning system for a hydropower station, including a data integration and analysis module, an early warning signal receiving and issuing module and a dam break early warning software which are electrically connected to the dam monitoring system in sequence; a broadcasting system which is electrically connected to the early warning signal receiving and issuing module, and the broadcasting system is electrically connected to the alarm tower; the dam break early warning software includes a self-rescue area map, an emergency drill plan and an emergency evacuation sign; the dam monitoring system is installed on the foundation structure of the hydropower station.

[0006] The data integration and analysis module receives, integrates and analyzes the data transmitted by the dam monitoring system, filters and processes the data, and determines whether the dam structure exceeds the preset value of the design safety standard.

[0007] The warning signal receiving and issuing module is used to receive the abnormal data determined by the data integration and analysis module and automatically trigger the warning program, issuing the warning information to the broadcasting system and the dam break warning software, and the broadcasting system sends an alarm to the alarm tower.

[0008] The dam break warning software receives and displays warning signals and provides evacuation routes and action instructions for personnel.

[0009] The self-rescue zone map is drawn in the dam break warning software according to the geographical location and road conditions of the area near the dam, showing the location of people near the hydropower station and the nearest safe evacuation routes and safe assembly points.

[0010] The broadcasting system and the alarm tower inform the internal staff of the hydropower station of the dam breach warning information in the first place.

[0011] The early warning method of the hydropower station dam breach early warning system as described above comprises the following steps: S1, monitoring data input: various structural data obtained from the dam monitoring system, including displacement, temperature, stress, and deformation data, are transmitted to the data integration and analysis module; S2, data preprocessing: preprocess different types of data from the dam monitoring system to remove duplicate data, erroneous data and missing values ​​to ensure data integrity and accuracy; S3, data integration: integrate the preprocessed data to form a unified data model; including the merging, connection, and association of data tables to ensure the relationship and consistency between the data; and after the data integration is completed, verify and check the integrated data to ensure the integrity, consistency, and accuracy of the data; S4, real-time analysis; perform data comparison and data quality check operations; form an overall data model of the dam structure, including spatial and temporal relationships; use data analysis technology to analyze and monitor real-time data in real time, identify abnormal patterns and early warning signals, and store and display them; S5, early warning triggering: monitoring whether the dam structure data is within the safety value, and when the analysis result exceeds the safety value, an early warning signal will be triggered; S6, warning release; after judging the correctness of the warning signal, the signal transmission is completed, and the warning signal is sent to the hydropower station work site and the communities around the dam synchronously through the broadcasting system and dam break warning software.

[0012] The workflow of the dam break warning software includes receiving warning information, warning prompts, displaying safe evacuation routes and assembly points, providing evacuation instructions, reminders and warnings, and recording and feedback.

[0013] The main beneficial effects of the present invention are: Advanced monitoring technology is used to monitor the safety status of the dam structure in real time, improve the accuracy and precision of monitoring, and issue early warning signals in a timely manner.

[0014] Compared with traditional early warning systems, this system may take into account multiple monitoring factors, such as geology, hydrology, structure, etc., to provide more comprehensive early warning information and reduce false alarm rates.

[0015] The design and configuration of emergency evacuation signs help improve the efficiency and safety of personnel evacuation, which may not be taken into account in traditional early warning systems. Luminous materials are used to consider power outages and nighttime situations.

[0016] Design intuitive and effective rescue mechanisms, including evacuation signs, rescue routes, etc., to improve the positioning of rescue personnel and rescue efficiency.

[0017] Comprehensive consideration has been given to the possibility of a hydropower station dam breach and response measures, not just early warning but also emergency evacuation and rescue, improving the overall ability to respond to disasters.

[0018] After the warning information is confirmed by the user, the dam break warning software can provide the best evacuation route and the nearest safe point location, improve the efficiency of personnel evacuating to the safe assembly point, and reduce personnel risks.

[0025] Preferably, the dam monitoring system 1 is a core component of the dam breach early warning system, which uses various sensors to monitor various parameters of the dam structure, such as displacement, pressure, temperature, water level, etc. These sensors collect data in real time to monitor the dam structure at all times and provide basic materials for data analysis.

[0026] In a preferred solution, the data integration and analysis module 2 receives, integrates and analyzes the data transmitted by the dam monitoring system 1, filters and processes the data, and determines whether the dam structure exceeds the preset value of the design safety standard.

[0027] Preferably, the data integration and analysis module 2 is to effectively process and analyze the massive data collected by the dam monitoring system through the data integration and analysis system, so as to timely and accurately evaluate the safety status of the dam. The data integration system can integrate the data from various sensors into a complete monitoring report and update it to the database in real time.

The system can identify potential dam breach risks according to preset safety standards and early warning thresholds, and automatically trigger the early warning mechanism when abnormal conditions are found.

[0030] Preferably, the early warning signal receiving and issuing module can receive the alarm signal issued by the data integration and analysis module. After the signal is transmitted to the early warning system receiving and issuing module, it can not only send alarm information to on-site staff through broadcasting, but also notify residents around the dam through the dam break early warning software, reminding them to take timely response measures.

[0031] In a preferred solution, the dam-break warning software 4 receives and displays warning signals and provides evacuation routes and action guidance for personnel, with the aim of ensuring that personnel evacuate to designated safe points in an orderly and safe manner.

[0032] In a preferred solution, the self-rescue area map 41 is drawn in the dam-break warning software according to the geographical location and road conditions of the area near the dam, showing the location of people near the hydropower station and the nearest safe evacuation route and safe assembly point location. Its purpose is to provide the best evacuation route guidance for the evacuees.

[0033] Preferably, the self-rescue area map 41 is to minimize the casualties and losses that may be caused by the dam breach accident, and plan the location of the self-rescue area and the evacuation route in advance. When designing the self-rescue area, it is necessary to consider the geographical location, population density, escape routes and other factors near the hydropower station to ensure that the self-rescue area can provide a safe refuge for residents around the dam in an emergency.

Emergency evacuation signs should be set at key locations of the dam, including entrances, exits, evacuation passages, safe areas, etc., to ensure that personnel can see the signs and act according to the instructions under any circumstances. The signs should be equipped with appropriate light source facilities to ensure that they can be clearly seen in dark or harsh conditions, thereby improving evacuation efficiency. Emergency evacuation signs can guide people to evacuate dangerous areas quickly and safely, reducing confusion and the risk of casualties.

[0035] Preferably, the emergency drill plan is a file set in the dam break warning software, including details of evacuation instructions, self-rescue area planning and design, emergency response plan, rescue process, material reserves, communication equipment, etc., to ensure that personnel can quickly and effectively organize evacuation and rescue work in an emergency.

[0036] Preferably, the emergency drill plan should be rehearsed and evaluated multiple times to ensure that it can be successfully implemented in actual emergency situations.

[0037] Preferably, the emergency evacuation sign is made of luminescent materials, such as fluorescent materials or luminous materials, which can emit light in a dark environment to ensure that it is still visible in situations such as power outages or at night.

[0038] Preferably, the dam break warning software 4 serves as a key tool for receiving warning information and guiding emergency evacuation. It promptly receives information from the warning system release module and provides specific guidance and action suggestions to assist personnel in quickly taking response measures. At the same time, the software has a location analysis function, and after arriving at a safe assembly point, the location can be shared to facilitate rescue by the rescue department.

[0039] Preferably, the dam-break warning software 4 is a dedicated software developed specifically for receiving flood or dam-break warning information of a hydropower station. The dam-break warning receiving software can provide information such as alarm information, self-rescue area maps, the fastest evacuation routes, the meaning of emergency evacuation signs, and the location of the nearest safe assembly point. The mobile phone software display is portable and instant, allowing users to obtain dam-break warning information anytime and anywhere, and enhance personal safety awareness.

[0040] In the preferred solution, the broadcasting system 31 and the alarm tower 32 notify the staff of the hydropower station of the dam breach warning information as soon as possible. The purpose is to prevent the staff in the hydropower station who do not have network or mobile phone signal settings from receiving the warning information notification as soon as possible, so as to play a role in prompting safe evacuation.

[0043] Embodiment 1, like Figure 1 In the present invention, a dam breach early warning system for a hydropower station includes a dam monitoring system 1 installed on the dam of a hydropower station. The monitoring system can obtain various structural data of the dam, such as displacement, temperature, stress and deformation, by using a variety of sensors and detectors. These data may be transmitted to a data integration and analysis module 2 in different formats.

[0044] Embodiment 2, like Figure 2 Among them, the data integration and analysis module 2 is a module that can use artificial intelligence algorithms to analyze and process the data collected by the dam monitoring system 1, so as to achieve the purpose of real-time monitoring of the dam status.

[0045] The data integration and analysis module 2 first preprocesses different types of data from the dam monitoring system 1, removes duplicate data, erroneous data and missing values, and ensures the integrity and accuracy of the data. Then the data are integrated together to form a unified data model. This involves the merging, connection and association operations of data tables to ensure the relationship and consistency between the data. After the data integration is completed, the integrated data needs to be verified and checked to ensure the integrity, consistency and accuracy of the data. Data comparison, data quality check and other operations can be performed. An overall data model of the dam structure is formed, including spatial and temporal relationships. Data analysis technology is used to analyze and monitor real-time data in real time, identify abnormal patterns and early warning signals, store and display them, and monitor whether the dam structure data is within the safety value. When the analysis results exceed the safety value, an early warning signal will be triggered.

[0046] Embodiment 3, like Figure 2 In the present invention, the warning signal receiving and issuing module 3 can receive the warning signal issued by the data integration and analysis module 2, complete the signal transmission function after judging the correctness of the warning signal, and send it to the hydropower station work site and the community around the dam synchronously through the broadcasting system 31 and the dam break warning software 4.

[0047] The broadcasting system 31 and the alarm tower 9 in this embodiment are multiple synchronous alarm towers and broadcasting systems installed in advance in the hydropower station to cover all areas in the power station, and serve the purpose of transmitting the early warning signal to the ears of the staff in the hydropower station. After hearing the alarm signal, the staff will evacuate along the nearest emergency evacuation route.

[0048] Embodiment 4, like Figure 2 Among them, the dam break warning software 4 is a visualization software specially introduced and installed on the mobile phone. In this software, you can clearly see the self-rescue area map 41, the best evacuation route, the emergency drill plan 42, the emergency evacuation sign 43 and the location sharing information, which provides all-round guidance for the evacuees and accurate positioning for the rescue departments, so as to achieve the purpose of rapid, orderly and safe evacuation of personnel.

[0049] The self-rescue zone map 41 is a detailed evacuation route and safety area information planned for residents based on the distribution of residents downstream of the dam, combined with an analysis of the surrounding geographical locations and road characteristics. This map is set in the dam break warning software 4, and users can check and familiarize themselves with the best evacuation routes and safe assembly points nearby based on their permanent locations.

[0050] Embodiment 4, like Figure 3 In the dam break warning software 4, after receiving the warning signal, the emergency response process is started, and a warning prompt will be given on the user side. The interface will display the warning information, including the warning level, specific problem description and emergency guidance. After confirming the information, the safe evacuation route and assembly point will be displayed. After the personnel start to move, real-time evacuation guidance will be given. When they reach the marked point drawn on the self-rescue area map, reminders and warnings will be given. The guidance program ends after the personnel safely evacuate to the safe assembly point, and the software automatically records the guidance process.

[0051] In the above multiple embodiments, each link plays an important role in the hydropower station dam breach warning system, and together builds a complete set of warning and emergency response mechanisms. Through high-end dam monitoring technology, fast data integration and analysis modules, and early warning signal receiving and sending modules, the warning signals of abnormal dam structure are judged and sent and received, and then the early warning signals are quickly transmitted through broadcast notifications and early warning software synchronization. Personnel can evacuate to a safe assembly point according to the self-rescue area map and emergency evacuation routes in the visual early warning software platform and the emergency evacuation signs. All links are interconnected and work together to effectively improve the coverage and response speed of the early warning system, and to maximize the protection of personnel and property safety.
