The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0032] The present invention provides a hydropower station emergency safety drill system based on UWB (Ultra Wide Band) positioning technology to improve the accuracy and efficiency of emergency safety drills.

[0033] In the first embodiment, Figure 1 is a block diagram of a hydropower station emergency safety drill system based on UWB positioning technology provided by an embodiment of the present invention.

[0034] As Figure 1 shown, the hydropower station emergency safety drill system based on UWB positioning technology includes a positioning module, a data acquisition module, and an emergency management module. The positioning module is connected to the emergency management module via the data acquisition module.

[0035] In the first embodiment, the positioning module includes UWB positioning base stations and UWB positioning tags. Each person is equipped with a corresponding UWB positioning tag. The positioning module is used to monitor the position information of personnel using UWB positioning technology. The number of UWB positioning base stations is multiple, and each UWB positioning base station is installed at key positions in the area where the emergency evacuation safety drill is carried out. Key positions include, but are not limited to, the entrance, passage, control room, powerhouse, distribution room, etc. of the hydropower station, which are key positions where emergency evacuation safety drills need to be carried out.

[0036] Specifically, UWB positioning base stations are installed at key locations such as the entrance, passage, control room, powerhouse, and distribution room of the hydropower station where emergency evacuation safety drills need to be carried out. A portable UWB positioning tag is equipped for each staff member and drill participant. By using the UWB positioning base stations deployed at key locations inside the hydropower station and the UWB positioning tags worn by personnel, centimeter-level high-precision real-time positioning can be achieved through UWB signals. Utilizing the characteristics of UWB positioning technology such as high bandwidth, low power consumption, and strong anti-interference ability, it is ensured that the personnel position information can be accurately obtained even in a complex electromagnetic environment, providing the command center with the real-time personnel distribution situation and facilitating the reasonable allocation of rescue forces.

[0037] In the first embodiment, the data acquisition module is used to obtain key element data in real time. The key element data includes personnel position information, personnel skill data, equipment data, and the set task priority data of the preset drill scenario.

[0038] Among them, the personnel position information comes from the positioning module. The personnel skill data includes data such as professional working hours and the number of training passes. The personnel skill data can come from the personnel information management system of the hydropower station. The equipment data includes equipment position information and equipment operating status, etc. The equipment data can come from the equipment management system. The set task priority data includes operation difficulty and danger level, etc.

[0039] The preset drill scenarios include but are not limited to scenarios such as fire, flood, and equipment failure.

[0040] In the first embodiment, the emergency management module includes a trained emergency dispatching model. The input of the emergency dispatching model is the key element data, and the output is the optimal task assignment plan. The optimal task assignment plan includes the evacuation route and the task list. The emergency management module is used to obtain the required optimal task assignment plan based on the key element data obtained in real time by using the trained emergency dispatching model when receiving a drill instruction. The task list includes the equipment to be operated and the operation sequence.

[0041] Among them, in the emergency task assignment scenario (i.e., different preset drill scenarios), the emergency management module encodes various key element data obtained by the data acquisition module in the emergency drill, such as the set task priority data, personnel skill data, equipment data, and personnel position information, into a state vector that can be recognized and processed by the model.

[0042] The emergency dispatch model adopts a deep reinforcement learning model. The encoded state vector is input into the emergency dispatch model for training. During the training process, the agent continuously interacts with the environment (i.e., the emergency drill scenario), continuously tries different task allocation actions, and updates its policy network parameters according to the reward signals given by the system after the actions (such as positive rewards like improved task completion efficiency and increased resource utilization rate, and negative rewards like task timeout and resource waste). After a large number of training iterations, the agent gradually learns the optimal task allocation scheme to be adopted in different scenarios.

[0043] When the emergency drill is actually carried out, the emergency management module converts the key element data obtained in real time into the corresponding real-time state vector, and uses the trained emergency dispatch model to quickly obtain the optimal task allocation scheme required in the current scenario.

[0044] In the second embodiment, Figure 2 is a block diagram of another hydropower station emergency safety drill system provided by an embodiment of the present invention based on UWB positioning technology.

[0045] As Figure 2 shown, the hydropower station emergency safety drill system based on UWB positioning technology includes a positioning module, a data acquisition module, an emergency management module, a drill evaluation module, and an emergency monitoring module. Among them, the functions of the positioning module, the data acquisition module, and the emergency management module can refer to the relevant descriptions in the first embodiment.

[0046] In the second embodiment, the emergency monitoring module is used to detect various environmental parameters of the hydropower station. The types of environmental parameters include temperature, smoke, water level, etc. The emergency monitoring module includes but is not limited to a temperature sensor, a smoke sensor, a water level sensor, etc. The monitoring points of various sensors cover the hydropower station area. The emergency monitoring module sends the collected data such as temperature, smoke, and water level to the data acquisition module for subsequent processing by the drill evaluation module. In this case, the data acquisition module is connected to the positioning module, the emergency monitoring module, and the equipment management system, etc., realizing the technical docking of the UWB positioning technology with the various systems of the hydropower station and the real-time sharing of data. Among them, the temperature sensor and the smoke sensor can monitor fire hazards, the water level sensor is used to monitor the risk of flooding, and the equipment operation status sensor can detect signs of equipment failure in time, providing real and comprehensive scenario data for the drill. Before the system is used, the positioning module is comprehensively tested to ensure the normal operation of the system.

[0047] In the second embodiment, the drill evaluation module is further configured to determine hazardous area information based on environmental parameters, and determine whether a person is in a hazardous area based on the personnel location information and the hazardous area information. Among them, if at least one value of temperature, smoke, water level, etc. exceeds the corresponding threshold value, the area where the corresponding monitoring point is located can be divided into a hazardous area. After determining the hazardous area, it is determined whether a person is in the hazardous area based on the personnel location information and the hazardous area information.

[0048] In the second embodiment, the drill evaluation module is further configured to, if in a hazardous area, adjust the task list in the optimal task allocation plan. For example, delete the equipment that needs to be operated in the hazardous area from the task list, and adjust the operation sequence so that the personnel can quickly leave the hazardous area according to the evacuation route.

[0049] In the second embodiment, the drill evaluation module is configured to determine whether a route deviation occurs based on the personnel location information and the evacuation route of the optimal task allocation plan.

[0050] In the second embodiment, the drill evaluation module is further configured to determine whether there is a congested area based on the personnel location information. If the number of people in a certain area exceeds the set value within the same time, that area is a congested area.

[0051] In the second embodiment, the drill evaluation module is further configured to, if in a congested area and there is an environmental risk warning in the congested area, adjust the evacuation route and the task list in the optimal task allocation plan. Among them, the environmental risk warning can be, for example, that at least one value of temperature, smoke, water level, etc. in the congested area exceeds the corresponding threshold value. For example, change the evacuation route and the task list of the personnel who are closer to the monitoring point of the emergency monitoring module (for example, within the preset range of the monitoring point) so that the corresponding personnel can quickly evacuate the congested area.

[0052] In the second embodiment, the drill evaluation module is further configured to obtain a drill result score based on the completion status of multiple project requirements. The project requirements include personnel preparation time, evacuation completion time, route selection, entering a hazardous area by mistake, task completion degree, etc. The scoring rules for each project requirement are shown in Table 1.

[0053] Table 1 Emergency drill score table

[0054]

[0055] Among them, for the personnel preparation time: Reading the task list and starting to handle it within the specified time can be based on the confirmation receipt time of the personnel after the optimal task allocation plan. If the confirmation receipt time is more than 1 minute later than the issuance time of the optimal task allocation plan, 2 points will be deducted, and for each additional minute exceeded, 3 more points will be deducted.

[0056] Regarding the evacuation completion time: The evacuation completion time refers to the time from the issuance of the optimal task allocation plan to the time when the personnel reach the designated safe area.

[0057] Regarding route selection: Calculate the similarity between the actual evacuation route of the personnel and the pre-determined route. If the similarity exceeds the set similarity threshold, it is considered to be basically coincident with the pre-determined route.

[0058] Regarding straying into dangerous areas: Based on the personnel location information and the dangerous area information, judge whether the personnel have appeared in the dangerous area and the number of times they have appeared in the dangerous area.

[0059] Regarding the task completion degree (i.e., the degree of completion of the emergency response work): Obtain the device status information of doors, windows, equipment, etc. in the area responsible for the personnel. If they are all in the closed state, it means that all are completed.

[0060] Regarding the smoothness of internal communication: Analyze the consistency between the task allocation plan feedback by the personnel and the task allocation plan given by the drill evaluation module. If the consistency is higher than the corresponding consistency threshold, it indicates that the smoothness of communication meets the standard.

[0061] Regarding the monitoring and feedback accuracy of Internet of Things devices: Analyze the consistency between the information of the Internet of Things devices feedback by the personnel and the device information given by the drill evaluation module. If the consistency is higher than the corresponding consistency threshold, it indicates that the monitoring and feedback accuracy of the Internet of Things devices meets the standard.

[0062] The drill evaluation module sums up the scores required for all the above items to obtain the drill result score.

[0063] In some embodiments, the specific process of the hydropower station emergency safety drill system based on UWB positioning technology is as follows:

[0064] 1) The system uses UWB positioning technology to collect the position data of the participants and equipment in real time. At the same time, obtain the personnel skill data from the personnel information management system of the hydropower station, obtain the equipment data from the equipment management system, and set the task priority data according to the preset drill scenario. Subsequently, integrate these multi-source data to form a unified data set, providing a comprehensive information basis for subsequent algorithm processing.

[0065] 2) Feature engineering and state encoding: Perform feature engineering processing on the collected data, extract key features and perform operations such as normalization to ensure the consistency and usability of the data. Then, encode the processed data into a state vector suitable for input to the deep reinforcement learning model. For example, for the personnel location, it is encoded in the form of coordinates combined with the area identifier; the personnel skills are digitally encoded through dimensions such as skill categories and proficiency levels; the equipment status is encoded with equipment operation parameters, fault status identifiers, etc.; the task priority is directly reflected in the state vector in the form of a (hazard + operation difficulty) numerical value.

[0066] 3) Decision making: Obtain the trained emergency dispatch model. When the emergency drill is actually carried out, the model quickly generates the optimal task allocation plan for the current scenario according to the state vector collected and processed in real time.

[0067] 4) When the personnel obtain the optimal task allocation plan and read their tasks and complete the tasks in sequence and according to the content, at the same time, the system reads the environmental and personnel location data in real time and continuously improves the task list and sequence for each person. The specific implementation method is as follows:

[0068] 41) After receiving the data, the big data analysis and processing module of the drill system immediately conducts analysis. For the personnel location data, analyze the movement trajectory of the personnel, judge whether they deviate from the predetermined route, and whether there are congested or inefficient areas. Combining with the environmental data, evaluate the impact of the current environment on the movement of personnel. For example, in a fire scene, according to the temperature and smoke concentration distribution, analyze whether the personnel are in a dangerous area and the restriction of the environmental changes in this area on the movement ability of the personnel. At the same time, based on the generated optimal task allocation plan, evaluate the current task execution situation and judge whether it is necessary to delete or adjust the subsequent tasks.

[0069] 42) Task list and sequence adjustment: Based on the data analysis results, the intelligent evaluation and feedback module generates adjustment suggestions. If it is found that the personnel in a certain area are too concentrated, affecting the rescue efficiency, and the environmental risk in this area is relatively high, such as too many people in the high-temperature area of the fire scene, the system will suggest reallocating the tasks of the personnel and transferring some personnel to other areas to perform rescue or auxiliary tasks. The adjusted task list and sequence are sent to the handheld terminal devices of the participants in the form of instructions through the visual interaction module. In addition, the commanders can also see the adjusted task arrangements on the large screen of the command center in real time, control the overall situation of the drill, and ensure that the entire drill process is continuously optimized according to the real-time data and actual situation, improving the drill effect and the ability to respond to emergencies.

[0070] 43) The system evaluates and scores the drill results.

[0071] 5) Drill evaluation: After the drill, analyze the UWB positioning data to evaluate the drill effect and put forward targeted improvement suggestions.

[0072] The system of the present invention uses UWB positioning technology to participate in emergency drills, which can accurately identify problems existing in each link during the drills, such as loopholes in drill organization, slow response, improper application of technology, etc., providing a clear direction for targeted improvement. It can also quantify the emergency drill effect scoring form. Through detailed evaluation indicators and quantitative scoring criteria, it realizes the scientific and objective evaluation of the emergency drill effect, avoiding the limitations of subjective judgment. The optimization suggestions generated based on the evaluation results contribute to continuously improving the drill plan, enhancing the capabilities of participants, optimizing resource allocation, etc., thereby continuously improving the quality and effect of emergency drills.

[0073] The following are the method embodiments of the present invention.

[0079] In the embodiment of the present invention, the method for emergency safety drills in hydropower stations based on UWB positioning technology further includes: obtaining a drill result score based on the completion of various project requirements, where the project requirements include personnel preparation time, evacuation completion time, route selection, entering a dangerous area by mistake, and task completion degree.

[0080] It should be noted that the above explanation of the embodiment of the system for emergency safety drills in hydropower stations based on UWB positioning technology also applies to the method for emergency safety drills in hydropower stations based on UWB positioning technology in this embodiment, and will not be elaborated here.

[0081] The serial numbers of the embodiments of the present invention above are only for description and do not represent the advantages or disadvantages of the embodiments.

In this case, compared with the traditional manual allocation or simple rule allocation method, using the trained emergency dispatching model can quickly complete the task allocation decision, improve the efficiency of the emergency safety drill. In addition, by integrating these key element data such as personnel position information, personnel skill data, equipment data, and the set task priority data of the preset drill scenario, and using the trained emergency dispatching model to obtain the required optimal task allocation plan, the accuracy of the emergency safety drill is improved.

[0083] The system and method of the present invention are an emergency safety drill system and method with high precision and strong real-time performance. The present invention has the following advantages:

[0084] 1) High efficiency: The present invention can complete the task allocation decision within milliseconds.

[0085] 2) Precision: Based on the comprehensive analysis of multi-source data, the algorithm can accurately match tasks with performers and equipment. It fully considers the adaptability between personnel skills and task difficulty, and the compatibility between equipment status and task requirements. For example, when performing a complex equipment repair task, the algorithm will give priority to allocating personnel with relevant professional skills and close to the equipment, and at the same time allocate equipment in good condition and suitable for the repair task, so as to improve the success rate and quality of task completion and realize the improvement of the accuracy of the emergency safety drill.

[0086] 3) Dynamic adaptability: In actual situations, the scenarios and boundary conditions that require emergency response often change rapidly.
