Description

Technical Field

[0001] The present invention belongs to the technical field of mobile power supplies, and in particular relates to an intelligent emergency mobile power supply and a control method thereof. Background Art

[0002] In modern society, power supply is the key to maintaining the normal operation of various infrastructures. However, natural disasters, equipment failures and other emergencies may cause power outages in the power grid, which in turn affects residents' lives and industrial and commercial activities. Therefore, power companies need to have the ability to respond quickly and restore power supply to reduce the impact of power outages on society and the economy. In this context, emergency mobile power supplies have been widely used as a flexible emergency power supply solution. Emergency mobile power supplies can quickly provide temporary power support when the power grid fails or the power supply is insufficient, ensuring the continuous power supply of critical loads.

[0003] Existing intelligent emergency mobile power control methods generally include dispatching emergency mobile power to the fault area for power supply through pre-set fixed paths and static strategies when a power grid fails. These methods usually rely on starting the emergency mobile power through manual instructions or preset programs after the fault occurs and moving it to a predetermined location. However, this static control method has some significant disadvantages: First, the existing technology lacks real-time monitoring and accurate analysis of the power grid status, resulting in delayed response of the emergency power supply and inability to timely understand the actual power supply situation of the power grid. The power shortage area may not be quickly located due to information delays. The existing technology often requires the configuration of multiple emergency mobile power supplies to cover the entire power grid, resulting in resource waste and overpowering problems. These shortcomings directly affect the emergency response efficiency and power supply stability of the power grid in emergencies. Summary of the invention

[0004] In view of this, the present invention aims to provide an intelligent emergency mobile power supply and a control method to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the technical solution provided by the present invention is as follows:

[0006] In a first aspect, the present invention provides an intelligent emergency mobile power control method, comprising the following steps:

[0007] The power grid monitoring node monitors the status information of the power supply area, and integrates the status information of each power supply area to obtain the power grid status information; the power supply area is a power grid divided into multiple independent power supply areas, and each area has a corresponding load unit and power supply path, and is arranged with a power grid monitoring node;

[0008] For the emergency mobile power supply in the standby position, connect it to the power grid and obtain the power grid status information;

[0009] When the power grid status information shows that the status information of the power supply area is abnormal, the connection point location information of the abnormal power supply area is obtained, and the optimal path for the emergency mobile power supply to reach the abnormal power supply area is calculated, and the emergency mobile power supply in the standby position is controlled to move along the planned optimal path to the connection point of the abnormal power supply area;

[0010] After the emergency mobile power source reaches the connection point in the abnormal power supply area, it is connected to the power grid interface in the abnormal power supply area, the emergency mobile power source is started, and power restoration to the abnormal power supply area begins.

[0011] Furthermore, the power grid monitoring node monitors the status information of the power supply area, and integrates the status information of each power supply area to obtain the power grid status information, including:

[0012] The power grid is divided into multiple independent power supply areas according to geographical scope, load units and power supply paths, and multiple power grid monitoring nodes are deployed in each power supply area. The power grid monitoring nodes cover the power supply lines and load points in the power supply area.

[0013] The power grid monitoring node collects the status information of the power supply area in real time, including voltage, current, power, frequency and power quality. The power grid monitoring node transmits the collected status information to the regional data aggregation library through wireless communication;

[0014] The received status information is processed through the regional data aggregation library to obtain analyzed status information, and the analyzed status information is transmitted to the power grid control system through the regional data aggregation library for integration to form power grid status information.

[0015] Furthermore, the step of forming the power grid status information includes:

[0016] The received status information is preprocessed through the regional data aggregation library, including data denoising, abnormal data removal and data format conversion;

[0017] Analyze the pre-processed status information, calculate the power parameters of the power supply area, and obtain analysis results. The power parameters include voltage deviation, load change rate, and frequency fluctuation;

[0018] Compare the analysis results with the preset abnormality identification criteria to identify the power supply areas with abnormalities. The abnormality identification criteria include voltage overrun, frequency deviation and overload.

[0019] The analyzed status information is transmitted to the power grid control system, and the power grid control system integrates the analyzed status information transmitted by multiple regional data aggregation libraries to form power grid status information.

[0020] Furthermore, the emergency mobile power supply in the standby position is connected to the power grid and obtains the power grid status information, including:

[0021] When the emergency mobile power supply is in the standby position, the emergency mobile power supply is in standby state and is connected to the power grid through the access point for power replenishment and information transmission;

[0022] The emergency mobile power supply is connected to the grid control system of the power grid to obtain the grid status information of the current power grid.

[0023] Furthermore, the step of obtaining the connection point location information of the abnormal power supply area and calculating the optimal path for the emergency mobile power supply to reach the abnormal power supply area includes:

[0024] When the acquired power supply area information shows that the status information is abnormal, the emergency mobile power supply starts the emergency power supply procedure;

[0025] The control system of the emergency mobile power source sets the priority of the path planning according to the urgency and load demand of the abnormal power supply area, and the control system of the emergency mobile power source sets the parameters of the emergency mobile power source mobile path planning, and the parameters of the path planning include the road length and the moving speed of the emergency power source;

[0026] Based on the parameters of the path planning, an optimal path calculation is performed, and a route with the shortest moving time and the lowest energy consumption is selected according to the optimal path calculation result, and a moving instruction is generated so that the control system of the emergency mobile power source controls the movement of the emergency mobile power source based on the moving instruction;

[0027] During the movement process, the path calculation results are updated in real time, and the moving path of the emergency mobile power supply is dynamically adjusted according to the calculation results.

[0028] Furthermore, in the step of updating the path calculation result in real time and dynamically adjusting the moving path of the emergency mobile power source according to the calculation result, the following steps are included:

[0029] When the emergency mobile power source starts to move along the optimal path, the surrounding road conditions are photographed in real time by a camera installed on the emergency mobile power source, and the road conditions are obtained by analyzing the images photographed by the camera through an image recognition system to obtain image data;

[0030] After the image data is transmitted to the control system of the emergency mobile power supply through the image recognition system, the control system of the emergency mobile power supply processes the collected image and identifies abnormal conditions in the image through an embedded image recognition algorithm;

[0031] When an abnormal situation is identified, the control system of the emergency mobile power supply recalculates the optimal path through image data analysis;

[0032] The control system of the emergency mobile power source generates a travel instruction through the re-performed optimal calculation result, so that the control system of the emergency mobile power source controls the movement of the emergency mobile power source based on the travel instruction.

[0033] Furthermore, in the step of updating the path calculation result in real time and dynamically adjusting the moving path of the emergency mobile power source according to the calculation result, it also includes:

[0034] As the emergency mobile power source continues to travel along the driving path, the camera will continue to monitor the road conditions ahead and update the image data through the image recognition system. If new obstacles or changes in road conditions are found, the system will adjust the path again.

[0035] When the emergency mobile power supply arrives at the predetermined target area, the control system of the emergency mobile power supply confirms the location of the target location, integrates the final moving path, driving time, energy consumption data and abnormal conditions into the first road condition information and stores it, and optimizes the route data of the target power supply area according to the first road condition information.

[0036] Further, the steps after the emergency mobile power source reaches the connection point in the abnormal power supply area include:

[0037] After the emergency mobile power source arrives at the connection point in the abnormal power supply area, the built-in positioning and navigation system is used to determine the location of the connection point. The automatic docking system connects the output interface of the emergency mobile power source to the grid interface in the abnormal power supply area.

[0038] After the connection is completed, the control system of the emergency mobile power supply performs connection stability and safety checks, and monitors the electrical parameters of voltage, current, and ground resistance in real time through the built-in electrical detection module;

[0039] During the detection process, check whether the output voltage matches the voltage of the target grid interface and confirm that the grounding resistance is within the safe range. If any abnormality is found, the control system of the emergency mobile power supply will automatically alarm and prevent further operation;

[0040] After completing the safety check, the control system of the emergency mobile power supply generates a connection status report, confirming that the connection is stable and meets the startup conditions, and starts the inverter and power output module of the emergency mobile power supply. The inverter will convert the DC power stored in the battery into AC power, and adjust the output voltage and frequency to synchronize with the target power supply area. The control system of the emergency mobile power supply monitors the voltage, frequency and phase of the grid interface in real time. After the synchronization is completed, the system automatically switches to the power supply mode and begins to restore power to the abnormal power supply area.

[0046] The control module is provided with a control system, which is used to calculate the optimal path and move the emergency mobile power supply body to the connection point of the abnormal power supply area according to the optimal path.

[0047] Furthermore, it also includes:

[0048] A camera is used to capture the surrounding road conditions of the emergency mobile power supply in real time;

The intelligent emergency mobile power supply and control method divides the power grid into multiple independent power supply areas, so that the power grid monitoring is more refined, which helps to accurately identify the power supply abnormality area (i.e., insufficient power supply area) and quickly locate the problem. The emergency mobile power supply is connected to the power grid and continuously receives the power grid status information to ensure that the emergency power supply can timely and accurately understand the power supply situation of the power grid, avoiding response delays due to grid status information data lag or lack of monitoring. When an abnormality occurs in the power supply area, the emergency mobile power supply can obtain information about the abnormal power supply area, automatically calculate the optimal path and quickly move to the abnormal power supply area, reducing manual intervention and improving the timeliness of power supply recovery. It can accurately replenish power to ensure that the power grid meets the load demand, while reducing the number of emergency mobile power supplies configured, avoiding power waste or over-power supply, and intelligent control, improving the power supply recovery capability of the power grid when the power supply is abnormal and the utilization efficiency of the emergency power supply, ensuring the stability of the power grid.

[0056] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] See also Figure 1 The embodiment of the present invention provides an intelligent emergency mobile power supply control method, comprising the following steps:

[0058] S1: Monitor the status information of the power supply area through the power grid monitoring node, and integrate the status information of each power supply area to obtain the power grid status information; the power supply area is to divide the power grid into multiple independent power supply areas, and each area has a corresponding load unit and power supply path, and is arranged with a power grid monitoring node.

[0059] In this step, the power grid is divided into multiple independent power supply areas, each of which has corresponding load units and power supply paths. The division facilitates the management of the power grid and optimizes the power supply needs of different areas. Power grid monitoring nodes are arranged in each power supply area. These nodes can monitor the voltage, current, power and other status information in the area in real time. The monitoring nodes transmit the collected data to the central control system, and the status information of the entire power grid is obtained by integrating and analyzing the status information of each power supply area. This process ensures a comprehensive grasp of the operating status of the power grid and provides data support for subsequent emergency response.

[0060] S2: For the emergency mobile power supply in the standby position, connect it to the power grid and obtain the power grid status information.

[0061] In this step, when the emergency mobile power supply is in the standby position, it obtains the status information of the power grid by connecting to the power grid. The emergency mobile power supply and the power grid are connected through communication (which can be connected through an interface or through wireless communication), and can synchronize the operation data of the power grid in real time, including key information such as voltage, current, and load. In this way, the emergency mobile power supply can continuously monitor the status of the power grid, and when an abnormality occurs in the power grid, it can quickly obtain relevant information and make response preparations.

[0062] S3: When the power grid status information shows that the status information of the power supply area is abnormal, the connection point location information of the abnormal power supply area is obtained, and the optimal path for the emergency mobile power supply to reach the abnormal power supply area is calculated, and the emergency mobile power supply in the standby position is controlled to move along the planned optimal path to the connection point of the abnormal power supply area.

[0063] In this step, when the grid status information shows that a power supply area has an abnormality (such as voltage fluctuation, load overload, etc.), the system will immediately obtain the specific location information of the abnormal power supply area and calculate the optimal path for the emergency mobile power supply to reach the abnormal power supply area. Factors considered include road length, moving speed and current road conditions. The emergency mobile power supply moves according to the calculated optimal path to ensure that it reaches the connection point of the abnormal power supply area at the fastest speed and lowest energy consumption. During the movement, the path calculation results will be updated in real time. The emergency mobile power supply can dynamically adjust the moving path according to the latest road condition information to avoid delays and obstacles.

[0064] S4: After the emergency mobile power source reaches the connection point in the abnormal power supply area, it is connected to the grid interface in the abnormal power supply area, the emergency mobile power source is started, and power restoration to the abnormal power supply area begins.

[0065] In this step, when the emergency mobile power supply reaches the connection point of the abnormal power supply area, the first step is to dock with the power grid interface of the area. After the docking is completed, the emergency mobile power supply is started, and its output voltage and frequency are synchronized with the power grid parameters. Then, the load is gradually increased to start providing power to the abnormal power supply area and restore the normal power supply of the area. During the power supply restoration process, the load is gradually loaded to avoid damage to the power grid and equipment caused by transient large current shocks. The power grid status is monitored in real time, and the output power of the emergency mobile power supply is adjusted to ensure stable power supply and avoid overload or undervoltage. Through this process, timely power restoration is achieved in the abnormal power supply area, ensuring the reliable operation of the power grid.

[0066] This embodiment provides an intelligent emergency mobile power control method, which divides the power grid into multiple independent power supply areas and arranges monitoring nodes to integrate power grid status information, allowing the standby emergency mobile power supply to access the power grid to obtain the information, and when the power supply area status is abnormal, the connection point location is obtained, the optimal path is planned for the emergency mobile power supply to go there, and after arriving, the power grid interface is connected to start power supply to restore power. Compared with the prior art, the control method provided in this embodiment divides the power grid into independent power supply areas and arranges monitoring nodes in power grid management, so as to achieve accurate monitoring of each area and comprehensive information integration, which is conducive to locating faults and accurately evaluating the operation status of the power grid; at the same time, it has an efficient emergency response mechanism, the emergency mobile power supply obtains the power grid status information in real time, responds quickly in abnormal situations, and quickly reaches the fault area through optimal path planning; and the control operation of this method is intelligent and highly automated, and the whole process of emergency dispatch does not require too much manual intervention. It is based on a large amount of data to drive decision-making, which is scientific and accurate, and improves the accuracy, reliability and risk resistance of emergency handling.

[0067] In one embodiment, S1 specifically includes:

[0068] S11. Divide the power grid into multiple independent power supply areas according to geographical scope, load units and power supply paths, and deploy multiple power grid monitoring nodes in each power supply area. The power grid monitoring nodes cover the power supply lines and load points in the corresponding power supply area.

[0069] In this step, the power grid is divided into multiple independent power supply areas according to the geographical scope, load unit and power supply path. The division helps to divide the power grid into smaller management units, which is convenient for accurate power dispatching and fault location. Multiple power grid monitoring nodes are deployed in each power supply area to monitor the power supply lines and load points in the corresponding power supply area. The layout of these monitoring nodes can comprehensively monitor the operating status of each key node and line, ensuring that any abnormal situation in any area during the operation of the power grid can be discovered and handled in time;

[0070] S12. The power grid monitoring node collects the status information of the power supply area in real time. The status information includes voltage, current, power, frequency and power quality. The power grid monitoring node transmits the collected status information to the regional data aggregation library through wireless communication.

[0071] In this step, each power grid monitoring node will collect status information of the power supply area in real time. This information includes key power parameters such as voltage, current, power, frequency and power quality, which can reflect the health status of the power grid. The monitoring node transmits the collected data to the regional data aggregation library through wireless communication methods (such as Wi-Fi, LoRa, NB-IoT, etc.). The use of wireless communication methods ensures fast data transmission and flexibility, avoids the wiring complexity of traditional wired communication methods, and improves the coverage and real-time performance of the monitoring system.

[0072] S13, the regional data aggregation library processes the received status information to obtain analyzed status information, and the analyzed status information is transmitted to the power grid control system through the regional data aggregation library for integration to form power grid status information.

[0073] In this step, after the regional data aggregation library receives the status information from each power grid monitoring node, it first processes the data, removes noise and performs necessary conversion and analysis. The processed status information will more accurately reflect the current operating status of the power grid, avoiding misjudgment due to data quality issues. The analyzed information will be transmitted to the power grid control system through the regional data aggregation library, and the power grid control system will integrate the information from each region to finally form the status information of the entire power grid. This process ensures that the power grid management system can obtain accurate power grid health data in real time, providing reliable support for subsequent emergency response and dispatch decisions.

[0074] In one embodiment, S13 specifically includes:

[0075] S131. The regional data aggregation library performs preprocessing on the received status information, including data denoising, abnormal data removal and data format conversion. The regional data aggregation library performs preprocessing on the received status information to ensure that the data quality meets the requirements of subsequent analysis.

[0076] In this step, firstly, data denoising is performed to remove the noise that may be generated by the sensor or communication process to ensure that the collected signal is more accurate. Secondly, abnormal data is eliminated to avoid abnormal values ​​caused by equipment failure or transmission errors affecting the analysis results. Finally, data format conversion is performed to convert data from different sources and different types into a unified format, making it easier to process and compare in the subsequent analysis process. The preprocessing process ensures the accuracy and consistency of the data.

[0077] S132. The regional data aggregation library analyzes the preprocessed status information, calculates the power parameters of the power supply area, and obtains analysis results. The power parameters include voltage deviation, load change rate and frequency fluctuation. The regional data aggregation library further analyzes the preprocessed status information.

[0078] In this step, the system comprehensively evaluates the operation status of the power grid by calculating the power parameters of the power supply area, including voltage deviation, load change rate and frequency fluctuation. The voltage deviation reflects the voltage stability of the power grid, the load change rate can reveal the fluctuation of the power grid load, and the frequency fluctuation reflects the frequency stability of the power grid. Through the calculation of these power parameters, the regional data aggregation library can obtain more detailed analysis results to help identify potential problems in the operation of the power grid;

[0079] S133. Compare the analysis result with a preset abnormality identification standard to identify the power supply area with abnormality. The abnormality identification standard includes voltage over-limit, frequency deviation and overload.

[0080] In this step, the regional data aggregation library compares the calculated analysis results with the preset abnormal identification standards. The abnormal standards include typical power grid abnormalities such as voltage overlimit, frequency deviation and overload. When the analysis results of a power supply area exceed the preset standard range, the system will determine that there is an abnormality in the area. Specifically, when the voltage exceeds the set upper and lower limits, the frequency deviates, or the load exceeds the load capacity of the power grid, the system will identify the abnormal area, and can quickly and accurately locate the abnormal power supply area in the power grid, which is convenient for subsequent emergency response and dispatch;

[0081] S134. The regional data aggregation library transmits the analyzed status information to the power grid control system. The power grid control system integrates the analyzed status information transmitted by multiple regional data aggregation libraries to form power grid status information. After receiving the analysis results from multiple regional data aggregation libraries, the power grid control system integrates the status information from different regions.

[0082] In this step, the power grid control system can fully grasp the health status of the entire power grid and form complete power grid status information. The integration process not only provides data support for real-time monitoring of power grid operation, but also provides basic data for dispatching decisions, fault location and emergency response, ensuring the efficient operation of the power grid management system.

[0083] In the above technology provided in this embodiment, the regional data aggregation library adopts a distributed data processing method, first pre-processes and analyzes the data in each region, and then transmits the analysis results to the power grid control system for centralized integration. This method not only reduces the processing burden of the power grid control system, but also makes full use of the computing resources of each region, and improves the processing efficiency of the entire system. At the same time, through centralized integration, complete power grid status information can be formed, providing strong support for the global management of the power grid.

[0084] In one embodiment, S2 specifically includes:

[0085] S21. When the emergency mobile power supply is in the standby position, the emergency mobile power supply is in standby state. It is connected to the power grid through the access point for power replenishment and information transmission. The emergency mobile power supply is in standby state and is ready to respond to the power supply needs of the power grid at any time. The emergency mobile power supply establishes a connection with the access point of the power grid to ensure that the emergency mobile power supply can be quickly activated when needed. Through this access point, the emergency mobile power supply can not only replenish power and maintain its own energy reserves, but also transmit information. In this process, the connection between the power supply and the power grid ensures two-way data flow: the power grid can monitor the status of the emergency mobile power supply (such as battery power, power supply status, etc.), and the emergency mobile power supply can receive power grid status information to prepare for subsequent power supply restoration. The monitoring and preparation work in the standby state ensure that the emergency mobile power supply can quickly respond to sudden demands of the power grid;

[0086] S22. The emergency mobile power supply is connected to the grid control system of the power grid to obtain the grid status information of the current power grid. The emergency mobile power supply establishes a connection with the grid control system of the power grid through the access point to obtain the current grid status information in real time. The grid control system provides grid information including voltage, current, frequency and load, so that the emergency mobile power supply can understand the current operation status of the power grid. The control system of the emergency mobile power supply determines whether there is any grid abnormality or an area that needs immediate power support based on this information. Through this process, the emergency mobile power supply can obtain accurate grid status and prepare for subsequent emergency dispatch and power supply restoration. The real-time data connection ensures the rapid response of the emergency mobile power supply in emergency situations and the accuracy of power dispatch.

[0087] In the above technology provided in this embodiment, when the emergency mobile power supply is in the standby position, a two-way connection is established with the power grid through an access point to realize the integration of power replenishment and information transmission functions, so that the power grid can monitor its status and receive power grid status information itself; at the same time, it is connected to the power grid control system of the power grid to obtain power grid information including voltage, current, frequency and load in real time, accurately judge power grid anomalies and areas requiring power support, and make preparations in advance based on this, to ensure that the emergency mobile power supply can quickly respond to sudden power grid demands in the standby state, realize rapid response and accurate power dispatch in emergencies, and improve the emergency handling capability and stability of the power grid system.

[0088] In one embodiment, S3 specifically includes:

[0089] S31. When the power supply area information obtained is abnormal status information, the emergency mobile power supply starts the emergency power supply program. When the power grid control system obtains abnormal status information of a power supply area, the control system of the emergency mobile power supply will immediately start the emergency power supply program. The abnormal information indicates that the power supply area may have problems such as voltage fluctuations, load overload, etc., resulting in its inability to supply power normally. When the power grid is abnormal, the emergency power supply program can be quickly started to enable the emergency mobile power supply to be moved to the abnormal power supply area;

[0090] S32. The control system of the emergency mobile power supply sets the priority of path planning according to the urgency and load demand of the abnormal power supply area. The control system of the emergency mobile power supply sets the parameters of the mobile path planning of the emergency mobile power supply. The parameters of the path planning include the road length and the moving speed of the emergency power supply. The control system of the emergency mobile power supply will collect the load level, voltage deviation, frequency fluctuation, load condition and key infrastructure of each power supply area in real time according to the urgency and load demand of the abnormal power supply area, for example, and score each indicator through preset weights and scoring criteria. The power supply area with high load scores high, the power supply area with large voltage deviation scores high, and the power supply area with high load scores high. If there are key facilities with high scores in the area, the scores of each indicator are weighted and calculated to obtain the comprehensive urgency score of each abnormal power supply area. According to the comprehensive urgency score, the abnormal power supply areas are sorted, and the power supply areas with high urgency are given priority. The priority of path planning is set, and the areas with high urgency will be given priority to ensure that the places that need power support the most can get emergency power supply in time. The control system will also set the mobile path planning parameters of the emergency mobile power supply. Through the road length and the emergency power supply moving speed parameters, the control system can optimize the mobile path of the emergency power supply to ensure that it reaches the abnormal area in the shortest time and completes the task with the minimum energy consumption;

[0091] S33. Based on the parameters of path planning, the optimal path is calculated. According to the result of the optimal path calculation, the route with the shortest moving time and the lowest energy consumption is selected, and a moving instruction is generated. The control system of the emergency mobile power source controls the movement of the emergency mobile power source based on the moving instruction. The path calculation will comprehensively consider factors such as road length, traffic conditions, and the moving speed of the emergency power source, and select the route with the shortest moving time and the lowest energy consumption. The generated moving instruction contains detailed path information and action plans to ensure that the emergency mobile power source can move along the optimal path. The control system will accurately control the movement of the emergency power source based on these moving instructions to ensure that it can efficiently and accurately reach the abnormal power supply area;

[0092] S34. During the movement, the path calculation results are updated in real time, and the moving path of the emergency mobile power supply is dynamically adjusted according to the calculation results. The emergency mobile power supply will update the path calculation results in real time during the movement to adapt to the immediate changes in roads and traffic. The real-time path adjustment mechanism improves the flexibility and response speed of the emergency power supply, ensuring that it can reach the target area quickly and safely.

[0093] In the above technology provided in this embodiment, the emergency mobile power supply can quickly start the emergency power supply program when the power supply area status information is abnormal. Then the control system sets the path planning priority according to the urgency of the abnormal power supply area (for example, by weighting and calculating the comprehensive urgency score of multiple indicators such as load level and voltage deviation and sorting) and load demand conditions, and sets parameters such as road length and emergency power supply moving speed; based on these parameters, the optimal path is calculated, the route with the shortest moving time and the lowest energy consumption is selected, and movement instructions are generated to control the movement of the power supply; and during the movement process, the path calculation results can be updated in real time, and the moving path can be dynamically adjusted according to the changes, so as to provide emergency power support for abnormal power supply areas efficiently, accurately and flexibly.

[0094] In one embodiment, S34 specifically includes:

[0095] S341. When the emergency mobile power source starts to move along the optimal path, the camera installed on the emergency mobile power source will take real-time photos of the surrounding road conditions. The image recognition system will analyze the images taken by the camera to obtain the road conditions and obtain image data. When the emergency mobile power source starts to move along the optimal path, the camera installed on the emergency mobile power source will take real-time photos of the road conditions around it. These cameras can capture image data of the road ahead and transmit the real-time acquired image data to the image recognition system. Through the real-time shooting of the camera, the emergency mobile power source can obtain the latest road conditions, including traffic conditions, road obstacles, road closures, etc. This step ensures that the emergency mobile power source can dynamically obtain road condition information along the way and provide basic data for subsequent path adjustments.

[0096] S342, after the image recognition system transmits the image data to the control system of the emergency mobile power supply, the control system of the emergency mobile power supply processes the collected image and identifies abnormal conditions in the image through an embedded image recognition algorithm. The image recognition system transmits the image data captured by the camera to the control system of the emergency mobile power supply. After the control system receives the image data, it processes and analyzes the data through an embedded image recognition algorithm. The image recognition algorithm can identify abnormal conditions in the image, such as traffic accidents, road closures, water accumulation and landslides, etc., which is a known technology. By processing and analyzing the image data, the control system can quickly identify road obstacles that affect the passage of the emergency mobile power supply. This step ensures that the emergency mobile power supply can detect changes in road conditions ahead in a timely manner;

[0097] S343. When an abnormal situation is identified, the control system of the emergency mobile power supply recalculates the optimal path through image data analysis. When the control system identifies an abnormal situation in the image, the system recalculates the optimal path through image data analysis. The control system comprehensively considers the current road conditions and the moving speed of the emergency power supply, and recalculates an optimal path to avoid obstacles. The recalculated path can ensure that the emergency mobile power supply bypasses obstacles in the shortest time and continues to move to the target area. This step ensures that the emergency mobile power supply can quickly adjust the path and maintain high mobility efficiency when encountering sudden changes in road conditions;

[0098] S344. The control system of the emergency mobile power supply generates driving instructions through the re-calculated optimal result. The control system of the emergency mobile power supply controls the movement of the emergency mobile power supply based on the driving instructions. The control system generates new driving instructions according to the recalculated optimal path. These driving instructions include new path nodes, turn instructions, estimated arrival time and other detailed information. The control system of the emergency mobile power supply adjusts the moving direction and speed based on these driving instructions to ensure that the emergency mobile power supply can continue to move along the new optimal path. The real-time path adjustment and driving instruction generation mechanism enable the emergency mobile power supply to flexibly respond to changes in road conditions and ensure safe and rapid arrival at the abnormal power supply area.

[0099] In the above technology provided in this embodiment, when the emergency mobile power supply moves, the camera captures the surrounding road conditions in real time to obtain image data. After transmitting it to the image recognition system, the control system uses an embedded image recognition algorithm to process the image and identify abnormal situations such as traffic accidents. Once an abnormality is identified, the control system combines image data analysis, current road conditions and moving speed to recalculate the optimal path, and then generates a driving instruction containing detailed information based on the new optimal calculation result, and then controls the emergency mobile power supply to adjust the moving direction and speed according to the new path, so as to achieve flexible response to changes in road conditions and safely and quickly reach the abnormal power supply area, thereby ensuring the efficiency and flexibility of the emergency mobile power supply during movement.

[0100] In one embodiment, S34 further includes:

[0101] S345. When the emergency mobile power source continues to travel along the driving path, the camera will continue to monitor the road conditions ahead and update the image data through the image recognition system. If new obstacles or changes in road conditions are found, the system will adjust the path again. When the emergency mobile power source continues to travel along the driving path, the camera installed on the emergency mobile power source will continue to monitor the road conditions ahead to ensure that the latest road conditions are obtained in real time. The image data captured by the camera will be processed and analyzed by the image recognition system to identify new obstacles or changes in road conditions that may appear on the road ahead. If new obstacles (such as traffic accidents or road closures) are found during driving, the system will immediately readjust the path to ensure that the emergency mobile power source can bypass these obstacles and continue to move along the optimal path. Through real-time monitoring and dynamic adjustment mechanisms, the emergency mobile power source can flexibly respond to various emergencies that may be encountered during driving, thereby improving the safety and efficiency of movement.

[0102] S346. When the emergency mobile power source arrives at the predetermined target area, the control system of the emergency mobile power source confirms the location of the target location. The control system of the emergency mobile power source integrates the final moving path, driving time, energy consumption data and abnormal conditions into the first road condition information and stores it, and optimizes the route data of the target power supply area according to the first road condition information. When the emergency mobile power source arrives at the predetermined target area, the control system of the emergency mobile power source will confirm the location of the target location to ensure that the emergency power source arrives at the designated location accurately. The confirmation process can be completed through the GPS positioning system and camera monitoring. After reaching the target, the control system of the emergency mobile power source will integrate all data in the entire moving process, including the final moving path, driving time, energy consumption data and abnormal conditions encountered. These data are integrated into the first road condition information and stored for further analysis and optimization. According to the stored first road condition information, the system will optimize the route data of the target power supply area, provide more reliable route planning data support for future emergency dispatch, and ensure that the dispatch of emergency power sources in subsequent tasks is more efficient and accurate.

[0103] In the above technology provided in this embodiment, on the one hand, during driving, the camera continuously monitors the road conditions ahead, updates the image data with the help of the image recognition system, and immediately adjusts the path again once a new obstacle or road condition change is found, so as to flexibly respond to emergencies and improve mobile safety and efficiency; on the other hand, when arriving at the predetermined target area, the control system confirms the location of the target location through GPS positioning and camera monitoring, integrates the final moving path, driving time, energy consumption data and abnormal conditions into the first road condition information and stores it, and optimizes the route data of the target power supply area based on this, providing a reliable planning basis for subsequent emergency dispatch, and ensuring efficient and accurate emergency power dispatch.

The control system of the emergency mobile power supply monitors the voltage, frequency and phase of the grid interface in real time. After the synchronization is completed, the system automatically switches to the power supply mode and starts to restore power to the abnormal power supply area. The inverter and power output module of the emergency mobile power supply are started. The inverter converts the DC power stored in the battery into AC power, and adjusts the output voltage and frequency to synchronize with the target power supply area. The synchronization process monitors the voltage, frequency and phase of the grid interface in real time to ensure that the output parameters of the emergency power supply are completely matched with the grid parameters. After the synchronization is completed, the system automatically switches to the power supply mode and starts to restore power to the abnormal power supply area. The control system of the emergency mobile power supply will continue to monitor the grid status to ensure stability and safety during the power supply restoration process. Through these steps, the emergency mobile power supply can quickly and stably provide power support to the abnormal power supply area and restore normal power supply.
