Description

Technical Field

[0001] The present invention relates to the technical field of power system management, and in particular to a power demand sensing system under emergency conditions. Background Art

[0002] In today's society, various emergencies and emergencies occur from time to time, such as natural disasters (earthquakes, floods, typhoons, etc.), public health events, major accidents, etc. In these emergency situations, the stability and reliability of power supply are crucial. Ensuring the normal operation of key facilities such as hospitals, emergency command centers, communication base stations, etc., and providing necessary power support for rescue operations is one of the key tasks in responding to emergencies.

[0003] However, there are many problems in sensing electricity demand in emergency situations. Traditional power monitoring systems mainly focus on power supply and management in normal operation, and are not sufficiently responsive to special needs in emergency situations. In the event of an emergency, due to the lack of effective methods for sensing electricity demand, it is often difficult to accurately understand the specific electricity demand in different regions and facilities, resulting in unreasonable allocation of power resources and failure to prioritize the most critical electricity demand.

[0004] On the one hand, existing electricity monitoring technologies may be severely affected in emergency situations. For example, natural disasters may damage power infrastructure, resulting in damage to monitoring equipment such as smart meters or interruption of communications, making it impossible to obtain accurate electricity data in a timely manner. At the same time, electricity demand changes rapidly in emergency situations, and traditional monitoring methods are difficult to quickly capture and analyze these changes, and cannot provide timely and effective basis for power allocation.

[0005] On the other hand, different types of emergency events correspond to different characteristics of electricity demand, but there is currently a lack of targeted perception methods. For example, rescue operations after an earthquake require a large amount of electricity for lighting and rescue equipment, while flood disasters may require continuous power supply to flood control facilities such as pumping stations. Due to the lack of electricity demand perception technology for these specific scenarios, the power supply often cannot meet actual needs, affecting the efficiency of emergency rescue and recovery work.

[0006] To sum up, in order to better respond to various emergency situations and improve the reliability and effectiveness of power supply, there is an urgent need for an innovative method of sensing power demand under emergency situations, so as to accurately and quickly understand the power demand under different scenarios and provide strong support for the rational allocation of power resources and the guarantee of key facility operation. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide an electricity demand perception system under emergency conditions, so as to accurately and quickly understand the electricity demand in different scenarios, improve the reliability and effectiveness of power supply, and provide strong support for the rational allocation of power resources and the guarantee of key facility operation.

[0016] Furthermore, the electricity demand perception system also includes a temporary electricity consumption area, and a temporary communication device is set in the temporary electricity consumption area. The temporary communication device communicates with the management system platform to apply to join the electricity consumption area map.

[0017] Furthermore, the electricity demand sensing system also includes a movable mobile maintenance vehicle, and the mobile maintenance vehicle communicates with the management system platform.

[0018] Beneficial effects of the present invention: The power demand sensing system in an emergency state of the present invention provides a new solution for power demand sensing by introducing drones as sensing nodes.

[0033] Furthermore, in one embodiment, the electricity demand sensing system further includes an interactive terminal, and the interactive terminal is electrically connected to the acquisition module.

[0034] Furthermore, in one embodiment, the interactive terminal may be a fixed terminal, and the fixed terminal is electrically connected to the acquisition module.

[0035] Furthermore, in one embodiment, the interactive terminal may also be a mobile terminal, the mobile terminal is interactively connected to the acquisition module, and the mobile terminal is interactively connected to the drone.

[0036] Furthermore, in one embodiment, the electricity demand sensing system also includes a management system platform, the acquisition module is connected to the management system platform via a wired network, and the drone communicates wirelessly with the management system platform.

[0037] Furthermore, in one embodiment, a power consumption area map is established in the management system platform, and the acquisition module serves as a network node for constructing the power consumption area map. The power consumption area map is used to construct an aerial distribution map of drones. The aerial distribution map includes multiple hovering points, and each of the drones is distributed at a corresponding hovering point.

[0039] Furthermore, in one embodiment, the electricity demand perception system also includes a temporary electricity consumption area, and a temporary communication device is set in the temporary electricity consumption area. The temporary communication device communicates with the management system platform to apply to join the electricity consumption area map.

[0040] Furthermore, in one embodiment, the electricity demand sensing system also includes a movable mobile maintenance vehicle, and the mobile maintenance vehicle communicates with the management system platform.

[0041] Electricity terminals represent various electricity-consuming devices or facilities, such as residential electricity-consuming devices, hospital medical equipment, and communication equipment in emergency command centers. These electricity terminals are the final users of electricity, and accurate perception of their electricity demand is crucial to ensuring key activities in emergency situations.

[0042] The acquisition module is connected to the power consumption terminal and is responsible for collecting the power consumption data of the power consumption terminal, including power consumption, voltage, current and other information. The acquisition module transmits this data to the drone through the communication module, providing basic data for the analysis and judgment of power demand.

[0043] The communication module realizes the communication between the acquisition module and the outside world, including wireless communication with the drone. The communication module needs to have high reliability and anti-interference capabilities to ensure stable transmission of power demand data in emergency situations.

[0044] As a key perception node, drones play the following important roles: (1) Flexible mobility: UAVs can fly freely in the power consumption area without being restricted by terrain and fixed facilities. In an emergency, they can quickly reach the disaster area or near key facilities and sense the power demand at close range.

[0045] (2) Mutual communication: Adjacent drones can communicate with each other to form a distributed perception network. This network structure can improve the coverage and accuracy of perception and avoid the impact of single point failures on the entire system.

[0046] (3) Data transmission: The drone can receive the power demand data sent by the collection module and transmit this data to the management system platform. At the same time, the drone can also combine the environmental information it collects (such as the disaster situation, the degree of damage to power facilities, etc.) with the power demand data to provide a more comprehensive reference for the allocation of power resources.

[0047] There are mainly the following ways of drone communication in emergency situations: (1) Mesh wireless ad hoc network communication Working principle: Multiple drones can form a distributed network through Mesh wireless ad hoc networking technology. Each drone can be used as a node in the network, and the nodes can communicate with each other and forward data. This communication method does not need to rely on fixed infrastructure and has strong flexibility and adaptability.

[0048] Communication characteristics: Mesh wireless ad hoc network communication has strong anti-interference and self-healing capabilities. Even if some nodes fail or communication is interrupted, the network can still maintain normal communication functions.

[0049] (2) Radio communications Working frequency band: Common drones use 2.4GHz or 5.8GHz radio frequency bands. The 2.4GHz band performs better in transmission distance and penetration, and is suitable for general control and data transmission; the 5.8GHz band has a faster data transmission rate and is suitable for scenarios that require high-speed data transmission, such as high-definition video transmission.

[0050] Communication characteristics: This communication method does not require the help of external network infrastructure. The drone can communicate directly with the ground control station or other drones, and has strong autonomy and independence. However, the communication distance is relatively limited, generally between a few kilometers and tens of kilometers, depending on the transmission power, environmental factors, and drone hardware configuration.

[0051] (3) Satellite communications Working principle: The drone establishes a connection with the satellite in space through the satellite communication module it carries, and uses the satellite as a relay station to achieve long-distance communication. Satellite communication is not affected by the ground environment and can cover a wide area. Even in remote areas or when the communication infrastructure is damaged, it can ensure smooth communication of the drone.

[0052] Communication characteristics: It has the advantages of wide coverage and high communication stability, but the communication delay is relatively high, the data transmission rate may be limited by the satellite bandwidth, and the use of satellite communication requires higher fees.

[0053] The collection module can communicate wirelessly with the drone through the corresponding communication module. The drone, as the intermediate transmission medium, collects and transmits the power consumption data of the power terminal. In an emergency, the fixed communication facilities on the ground may be damaged, and the drone can quickly establish a connection between the power terminal and the outside world with its flexible communication method, ensuring that the power consumption data can be obtained in a timely manner.

[0054] Adjacent drones can communicate with each other, and this communication method enables drones to form a distributed perception network. After each drone collects power consumption data or other related information, it can share it with other drones through communication, thereby expanding the perception range and improving the accuracy and comprehensiveness of power demand perception.

[0055] The environment in an emergency is complex and changeable, and different disaster types and scenarios have different requirements for communication methods. The drone's multiple communication methods can be selected and switched according to actual conditions to ensure normal operation under various harsh conditions.

[0056] Drones have a variety of communication methods. When one communication method is disturbed or fails, it can quickly switch to other communication methods to ensure the stability and reliability of the power demand perception system. The communication method of drones can realize the real-time transmission of power consumption data, so that relevant departments can promptly understand the changes in power demand under emergency conditions. This is crucial for making decisions quickly and allocating power resources reasonably. During the communication process, drones can not only transmit power consumption data, but also transmit the environmental information they collect (such as disaster conditions, degree of damage to power facilities, etc.). These comprehensive information can provide a more comprehensive reference for emergency decision-making and help relevant departments formulate more scientific and reasonable power demand perception and power allocation plans.

[0057] The electricity terminal includes an electricity load and an energy meter. The electricity load is connected to the energy meter, and the energy meter is connected to the acquisition module. The energy meter is an instrument used to measure electric energy, which can measure the electricity consumption of the electricity load. As a professional instrument for measuring electric energy, the energy meter can accurately measure the power consumption, voltage, current and other parameters of the electricity load. By directly connecting to the electricity load, the accuracy and reliability of the measurement data are ensured. This is crucial for accurately sensing electricity demand in emergency situations, because only by mastering accurate electricity consumption data can we reasonably allocate power resources and ensure the normal operation of key facilities.

[0058] The connection between the energy meter and the acquisition module has become an important bridge for data transmission between the power terminal and the external system. The acquisition module can obtain detailed power consumption data of the power load through the connection with the energy meter, and transmit these data to the drone or other receiving devices through the communication module. This connection method enables the power consumption data to be quickly and accurately transmitted to the decision-making center, providing timely information support for power allocation in emergency situations. The energy meter can quickly reflect the changes in power consumption of the power load. Once there is an abnormality in power consumption, such as a sudden increase or decrease in power consumption, voltage fluctuations, etc., it can be discovered in time through the connection with the acquisition module. This helps to quickly respond to possible power failures and take timely measures to repair or adjust the power supply strategy.

[0059] In an emergency, power resources are often limited. By measuring the power load with an energy meter, we can understand the specific power demand of each power terminal, thereby achieving the optimal allocation of power resources. According to the importance and urgency of different power terminals, power resources are reasonably allocated to ensure the power supply of key facilities and rescue operations. The accurate measurement and stable operation of the energy meter provide a reliable data foundation for the entire power demand perception system. In an emergency, the reliability and stability of the system are crucial, and failures in any link may affect the smooth progress of emergency rescue and recovery work. The close connection between the energy meter, the power load and the acquisition module ensures the continuous collection and transmission of power data, and improves the overall reliability and stability of the system.

[0060] The interactive terminal can provide users with a way to interact with the management system platform. The interactive terminal is a fixed terminal connected to the acquisition module. The role of the fixed terminal: As a fixed terminal connected to the acquisition module, it provides users with a reliable way to interact with the management system platform. In an emergency, it can continuously and stably receive and feedback power demand information. The fixed terminal can centrally process and monitor the power consumption data transmitted by the acquisition module. It can display the real-time power consumption of each power terminal in the power consumption area, helping managers to fully understand the power usage status so as to make reasonable decisions.

[0061] The interactive terminal can be a mobile terminal, which can be interactively connected with the collection module, and the mobile terminal can be interactively connected with the drone. The role of the mobile terminal: The mobile terminal brings great flexibility to the perception of electricity demand in emergency situations. It can be interactively connected with the collection module anytime and anywhere, so that users can understand the electricity consumption situation and put forward their needs in time on site. The mobile terminal can be interactively connected with the drone, further expanding the scope and ability of electricity demand perception. In an emergency, the drone can quickly reach the disaster area to collect and transmit electricity data, and the mobile terminal can receive the information sent by the drone and feedback the on-site situation to the drone or the management system platform.

[0062] Comprehensive advantages of interactive terminals: The existence of interactive terminals enables users to interact with the management system platform in a timely manner and quickly feedback electricity demand and on-site conditions. This helps to improve the speed of emergency response and ensure that power resources can be deployed to the most needed places in the shortest time. The real-time power consumption data and on-site information provided by the interactive terminal provide a basis for managers to make accurate decisions. Through the interactive use of fixed terminals and mobile terminals, we can fully understand the power demand situation under emergency conditions and formulate more scientific and reasonable power allocation plans. The diversified connection methods and flexible use methods of interactive terminals make the power demand perception system more adaptable and flexible under emergency conditions. Whether in a fixed place or at a mobile rescue site, it is easy to interact and transmit data to meet the power demand perception and management requirements in different scenarios.

[0063] The acquisition module is connected to the management system platform through a wired network, and the drone can communicate with the management system platform wirelessly. As the core hub, the management system platform receives power consumption data from each acquisition module through a wired network. These data include the measurement data of the electric energy meter of different power consumption terminals, the operating status of the power load, etc. In an emergency, it is crucial to be able to quickly and accurately obtain comprehensive power consumption information. The management system platform has strong data processing capabilities and can analyze the received power consumption data. Through data analysis, it is possible to identify the changing trend of power demand, abnormal power consumption, and the priority of key power consumption terminals. This helps to reasonably allocate power resources in an emergency and ensure that the places that need power the most are given priority.

[0064] As a flexible sensing node in an emergency, the drone can communicate wirelessly with the management system platform. The management system platform can receive on-site images, environmental information, and supplementary data on power demand transmitted by the drone. At the same time, the platform can also send instructions to the drone to guide it to perform more detailed power demand sensing tasks in specific areas. The management system platform coordinates the allocation of power resources based on the analysis results of power consumption data. It can interact with the dispatching system of the power department to formulate a reasonable power allocation plan to ensure the power supply of key facilities and rescue operations in an emergency.

[0065] The management system platform integrates various information on power demand perception, providing strong support for emergency decision-making. Managers can intuitively understand the power consumption, drone monitoring results, and the distribution of power resources through the platform, so as to make scientific and reasonable decisions. The management system platform can quickly respond to various emergencies, promptly launch emergency plans, and coordinate resources from all parties for emergency disposal. It can achieve rapid perception of power demand and efficient allocation of power resources through close cooperation with the acquisition module, drones, and power departments.

[0066] A power consumption area map is established in the management system platform, and several acquisition modules serve as network nodes for constructing the power consumption area map. The aerial distribution map of drones is constructed through the power consumption area map. The aerial distribution map includes several hovering points, and several drones are distributed at the corresponding hovering points. The response area map is constructed through the interaction between the drone and the acquisition module. The response area map can be compared with the power consumption area map to make a judgment on the fault area.

[0067] The role of the electricity consumption area map: (1) Visual presentation of power consumption layout: The power consumption area map in the management system platform provides an intuitive visualization interface for the entire emergency power demand perception system. By using several acquisition modules as network nodes to construct the power consumption area map, the distribution of each power consumption terminal in the power consumption area and the layout of power facilities can be clearly displayed.

[0068] (2) Assist decision-making: The power consumption area map not only shows the location of the power consumption terminal, but also provides an important basis for decision-making in combination with the power consumption data transmitted by the acquisition module. Managers can reasonably allocate power resources and formulate the optimal emergency power supply plan based on the power demand of different areas on the map.

[0069] Construction and function of aerial distribution map: (1) Planning UAV deployment: Using the power consumption area map to build the UAV aerial distribution map provides a scientific plan for the deployment of UAVs. The hovering points in the aerial distribution map are determined according to the characteristics and needs of the power consumption area. The UAVs are distributed at the corresponding hovering points, which can achieve comprehensive coverage and efficient monitoring of the power consumption area.

[0070] (2) Improve monitoring efficiency: Aerial distribution maps make drone monitoring tasks more orderly and efficient. By assigning drones to different hovering points, repeated monitoring and the occurrence of monitoring blind spots can be avoided, improving the accuracy and comprehensiveness of electricity demand perception.

[0071] Construction and function of response area map: (1) Real-time reflection of electricity consumption The response area map is constructed through the interaction between the drone and the collection module, which can reflect the power consumption response of each part of the power consumption area in real time. The response area map can show which areas have normal power consumption and which areas have faults or abnormal conditions.

[0072] (2) Rapid fault diagnosis Comparing the response area map with the power consumption area map can determine the fault area, which greatly improves the speed and accuracy of troubleshooting. By comparing the two maps, it is possible to quickly determine which areas have power consumption that is not in line with expectations, thereby determining possible fault areas.

[0073] A drone replacement station is established, and the distance between the hovering point and the drone replacement station is stored as A. The drone sends the remaining range information to the management system platform in real time, and the remaining range is B. When B < 2.5A, the management system platform sends a dispatch command to the drone replacement station, and the drone replacement station dispatches the drone to the corresponding hovering point. When the drone flies to the corresponding hovering point, the original drone is replaced, and the original drone at the hovering point flies back to the drone replacement station for charging. The drone replacement station is a fixed setting or a movable setting.

[0074] In an emergency, the endurance of a drone is crucial. When the remaining range information B sent by the drone to the management system platform in real time is less than 2.5A, the management system platform sends a dispatch command to the drone replacement station. This ensures that a new drone is promptly arranged to go to the hovering point for replacement before the drone's battery is about to run out. The existence of the drone replacement station greatly improves the reliability of the entire power demand perception system. Even if individual drones fail or are low on power, the normal operation of the system can be guaranteed by timely replacement. This is crucial for critical tasks in an emergency, ensuring the continuous collection and transmission of power demand information.

[0075] Fixed drone replacement stations are usually located in key locations in power consumption areas, with stable power supply and equipment maintenance conditions. It can serve as a long-term infrastructure to provide reliable protection for the replacement and charging of drones. Mobile drone replacement stations have greater flexibility. In an emergency, it can be quickly deployed to different locations according to actual conditions to meet the power demand perception tasks in different areas. The management system platform reasonably arranges the delivery tasks based on the remaining range of the drone and the distance A between the hovering point and the drone replacement station. When a new drone needs to be dispatched, the management system platform will select the drone replacement station closest to the hovering point for delivery to reduce delivery time and energy consumption.

[0076] The establishment of a drone replacement station helps to use energy efficiently. When a low-battery drone flies back to the replacement station for charging, it can use the stable power supply of the replacement station to quickly charge, thereby improving energy efficiency. At the same time, newly dispatched drones can carry sufficient power to the hovering point, reducing the frequent replacement due to insufficient power. To ensure that the drone replacement station has a reliable source of power, you can consider connecting to a backup power source, such as a solar power generation system, emergency generator, etc. In an emergency, the power supply may be unstable, and the backup power supply can be started in time when the main power supply fails to ensure the normal operation of the replacement station.

[0077] The management system of the drone replacement station is integrated with the management platform of the entire power demand sensing system to achieve data sharing and remote monitoring. Through the management platform, you can get real-time information such as the operating status of the replacement station, the delivery of drones, and the battery charging progress.

[0078] An intelligent scheduling algorithm can be developed to automatically arrange delivery tasks based on factors such as the remaining range of the drone, the distance between the hovering point and the replacement station, and the urgency of the task. The algorithm should take into account energy consumption, time cost, and task priority to achieve optimal resource allocation. When multiple drones need to be replaced at the same time, the algorithm can give priority to the drone with the closest distance, the most sufficient battery, and the most urgent task based on factors such as distance, power, and task urgency. At the same time, the algorithm can also arrange delivery tasks in advance based on historical data and prediction models to improve the response speed of the system. Alternatively, after receiving the delivery order, the drone replacement station can execute the delivery order through staff.

[0079] Temporary communication equipment is set up in temporary power-using areas, which can communicate with the management system platform to apply to join the power-using area map. In an emergency, the establishment of temporary power-using areas such as temporary command rooms and communication towers is crucial. These areas undertake key tasks such as coordinating rescue operations and ensuring smooth information flow, and have an urgent need for power supply. After a disaster occurs, the establishment of a temporary command room can centrally command rescue forces and allocate resources, while the communication tower ensures communication between the disaster area and the outside world. A stable power supply is the basis for the normal operation of these temporary power-using areas.

[0080] The establishment of temporary power areas can quickly improve emergency response capabilities. They can be set up in a short time to provide timely support for rescue work and make up for the damage or shortage of original power facilities. Temporary communication equipment can communicate with the management system platform, which enables temporary power areas to apply to the management system platform to join the power area map in a timely manner. In this way, the management system platform can understand the location and power demand of temporary power areas in real time, so as to better allocate and manage power resources.

[0081] Temporary communication equipment is not only used to communicate with the management system platform, but also to transmit information within the temporary power consumption area and between other emergency departments. They can ensure the timely communication of information such as command decisions, rescue instructions and on-site conditions, and improve the coordination of emergency response. When the temporary power consumption area applies to join the power consumption area map through temporary communication equipment, the management system platform can incorporate it into the overall power demand perception system. This can achieve comprehensive coverage of the entire power consumption area and ensure that no important power demand points are missed.

[0082] The management system platform can optimize the allocation of power resources based on the application of temporary power consumption areas and the demand of other power consumption terminals. This can ensure that in an emergency, limited power resources can give priority to meeting the most urgent and important power needs.

[0083] The mobile maintenance vehicle can communicate with the management system platform and can be used to patrol the disaster area and perform necessary maintenance. The mobile maintenance vehicle is highly mobile and can respond quickly to the needs of the disaster area. In an emergency, time is of the essence. The mobile maintenance vehicle can reach the disaster site in the shortest possible time to patrol and maintain the damaged power facilities. The mobility of the mobile maintenance vehicle enables it to flexibly adapt to a variety of different emergency scenarios.

[0084] The mobile maintenance vehicle can communicate with the management system platform, which allows it to receive instructions and information from the management system platform in real time. The management system platform can determine the areas and equipment that need maintenance based on the data of the power demand perception system, and assign tasks to the mobile maintenance vehicle. When the management system platform detects that the power terminal in a certain area has a fault or the power demand is abnormal, it can send a task instruction to the mobile maintenance vehicle, requiring it to go to the area for inspection and maintenance. At the same time, the mobile maintenance vehicle can also feedback the situation on site to the management system platform so that the platform can make more accurate decisions.

[0085] The mobile maintenance vehicle can conduct a comprehensive inspection of the affected area to check the damage to the power facilities. It can be equipped with advanced detection equipment, such as infrared thermal imagers, drone inspection systems, etc., to quickly detect power lines, transformers, distribution boxes and other equipment to find potential fault points. When power facilities are found to be damaged, the mobile maintenance vehicle can perform necessary maintenance and repair work. It can carry various tools and equipment, such as cable connectors, insulation materials, maintenance tools, etc., to repair damaged power facilities on site.

[0086] In summary, the power demand perception system in an emergency state of the present invention provides a new solution for power demand perception by introducing drones as perception nodes. Several power terminals are distributed in the power consumption area, and each power terminal is connected to a corresponding collection module, and the collection module communicates with the outside world through a corresponding communication module. At the same time, several drones are distributed in the power consumption area, and each drone serves as a perception node.
