[0020] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0021] The first implementation method: Figure 1-Figure 7 As shown, it includes a decision-making support platform, a data acquisition module and an energy storage management module, and the energy storage management module is connected to a plurality of energy storage containers 1 for storing energy storage units; The data acquisition module is used for data acquisition of the status of associated equipment and energy storage units and environmental data acquisition. The associated equipment includes electrical equipment and other equipment; The data collection module is connected to a patrol robot and a meteorological data collector; The inspection robot is used to perform temperature detection, corona discharge detection and abnormal sound detection on the associated equipment and energy storage units; the inspection robot includes: wheeled robots; The inspection robot is equipped with a multispectral imaging module and a voiceprint collection sensor (covering the 20Hz-20kHz frequency band). The multispectral imaging module collects light, infrared light and ultraviolet light in three channels simultaneously. The inspection robot uses an infrared thermal imager to measure temperature, a voiceprint collection sensor to collect abnormal noises from the equipment, and an ultraviolet imager to perform corona discharge detection to jointly collect equipment status data, making it easy to accurately identify defects in equipment and energy storage units. The inspection robot is also provided with a laser radar and a navigation unit, which is easy to achieve accurate positioning. The laser radar and the navigation unit are both set by a person skilled in the art using relevant equipment in the prior art to ensure that the inspection robot can navigate along the inspection route for inspection; The meteorological data collector is used to collect 72 hours of meteorological data; The auxiliary decision-making platform is equipped with a risk assessment module and an inspection decision module. The risk assessment module classifies the health status of related equipment based on the collected related equipment status data and meteorological data; each level is equipped with a different inspection process; The inspection decision module sets the inspection path according to the health status of the energy storage unit and the associated equipment. The priority of the inspection path is set according to the health status of the associated equipment and the energy storage unit. The inspection route includes the coordinates of the associated equipment, the coordinates and number of the energy storage container 1, and the energy storage unit number; for example: energy storage container 1 number: A1, energy storage unit number: A1-R1-002.

[0022] Two rows of energy storage cabinets 2 for placing energy storage units are arranged in pairs in the energy storage container 1. A lifting rail 3 for lifting and moving the inspection robot is arranged between the pair of energy storage cabinets 2. A docking charging unit 33 for charging and data transmission of the inspection robot is installed on the lifting rail 3. The docking charging unit 33 is electrically connected to the energy storage cabinet 2. A control unit and a data storage unit are arranged in the docking charging unit 33. The data storage unit stores the corresponding coordinate information of each numbered energy storage unit in the energy storage container 1. The coordinate information includes the placement height of the energy storage unit and the horizontal straight-line distance relative to the docking charging unit 33 and the left and right direction relative to the docking charging unit 33. For example, the coordinate information corresponding to the energy storage unit numbered A1-R1-002 is: (20, 50, left); The inspection robot is equipped with a telescopic docking joint that matches the docking charging unit 33, and the telescopic docking joint specifically includes an electric push rod and a joint; When the inspection robot moves to the docking and charging unit 33, it docks once and uploads the energy storage unit number. After receiving the energy storage unit number, the docking and charging unit 33 feeds back the energy storage unit positioning information to the inspection robot. At this time, the lifting guide rail 3 moves its active end up to the corresponding placement height of the energy storage unit with the number according to the energy storage unit number, and feeds back the position information of the energy storage unit with the number. At this time, the inspection robot moves along the active end of the lifting guide rail 3 on the drive to reach the energy storage unit to be inspected; when the inspection robot moves on the lifting guide rail 3, it can detect all the energy storage units on the energy storage cabinet 2.

[0023] This solution does not involve the positioning information of the energy storage unit in the inspection path, so as to avoid the positioning information occupying too large a proportion of the inspection robot's memory when inspecting a large number of energy storage units. It is not easy to cause the stored inspection data to be lost due to the excessive proportion of data memory. Only the energy storage unit number information is saved. After the inspection robot arrives at the corresponding container, the energy storage unit coordinate information is obtained according to the number information, which ensures the inspection robot's accurate positioning of the energy storage unit and realizes the memory optimization of the inspection robot.

[0024] The meteorological data collector obtains meteorological data from meteorological satellites, ground micro-meteorological stations and lightning positioning systems. After collecting data, the meteorological data collector constructs a 72-hour dynamic map of power transmission environmental risks and updates the dynamic map every 36 hours. The risk dynamic map shows the changing trend of the power transmission environment in each period of the next 72 hours and the corresponding risk assessment parameters for each period, providing accurate data support for the risk assessment module; the risk assessment module conducts risk assessment on the equipment or energy storage unit in each period according to the corresponding risk assessment parameters combined with the data collected by the inspection robot. The technicians in this field use appropriate algorithms in the prior art to conduct risk assessment in combination with the risk dynamic map and the data collected by the inspection robot, for example: using machine learning algorithms, by training a large amount of historical data, to establish a risk assessment model to achieve accurate classification of the health status of the equipment or energy storage unit. The risk dynamic map can also provide data support for risk assessment when the system is in an isolated island operation state.

[0025] The risk assessment module combines the associated equipment status data and risk dynamic map to more comprehensively evaluate the equipment health status and ensure the scientificity and effectiveness of inspection decisions.

[0026] The risk assessment module is set with five risk levels: normal, caution, abnormal, severe and crisis. Different inspection processes are set for energy storage units and related equipment at each risk level. The specific inspection processes include: At the normal level, the inspection frequency is low, and routine inspections are carried out regularly, and routine inspections only carry out temperature detection; When paying attention to the level, increase the number of inspections; When the level is abnormal, start special inspections, focus on monitoring the associated equipment or energy storage units, and add abnormal sound collection and corona discharge detection to the associated equipment or energy storage units; When the situation is serious, further strengthen the inspection, shorten the inspection cycle, and take necessary emergency measures, such as notifying technical personnel; When the crisis level is reached, emergency inspections are immediately carried out and emergency plans are initiated. The emergency plans are set by technical personnel in the field, such as cutting off related equipment or energy storage units or notifying technical personnel to carry out emergency maintenance and other measures to ensure the safe operation of equipment and systems.

[0027] The risk assessment module realizes dynamic adjustment and real-time update of risk levels, and can flexibly adjust inspection strategies according to actual conditions to improve inspection efficiency and accuracy. In addition, the risk assessment module can also combine real-time data and trend analysis to predict possible future risk situations and provide forward-looking decision support for inspection work.

[0028] Optionally, the energy storage cabinet 2 allocates energy storage units to the electrical equipment based on the importance level of the electrical equipment. The energy storage units are allocated in an associated manner according to the principle of N+X, where N represents the number of standard energy storage units required for the electrical equipment, and X represents the number of spare energy storage units corresponding to the importance level of the electrical equipment. The above energy storage unit allocation is selectively set by those skilled in the art according to actual needs. When the energy storage unit is in an abnormal state, it can be quickly cut off and the backup energy storage unit can be switched to supply power to the electrical equipment to ensure stable power consumption of the electrical unit; the intelligent allocation strategy of the energy storage cabinet 2 not only meets the energy storage needs of electrical equipment of different levels, but also effectively improves the utilization rate of the energy storage unit and the overall efficiency of the system.

[0029] In summary, the present invention introduces an auxiliary decision-making platform, a data acquisition module and an energy storage management module to enable the inspection robot to move on the lifting guide rail 3 to perform accurate autonomous inspection and charging of the energy storage unit. At the same time, the system can dynamically adjust the inspection path and frequency according to meteorological data and equipment status data to ensure that the inspection device can stably and timely inspect the energy storage unit and related equipment.

[0030] Second implementation method: Figure 3 - Figure 7 As shown, the lifting guide rail 3 includes a pair of lifting frames 31, a horizontal guide plate 32 is connected between the movable ends of the pair of lifting frames 31, a docking charging unit 33 is installed at one end of the horizontal guide plate 32, and a power supply cable is connected between the docking charging unit 33 and the energy storage cabinet 2, and a telescopic joint matching the docking charging unit 33 is connected to the inspection robot.

[0031] A double-axis motor connected to the docking charging unit 33 is installed at the top end of the lifting guide rail 3; A screw rod is rotatably connected inside the lifting frame 31, a bracket matching the horizontal guide plate 32 is threadedly connected to the screw rod, and a transmission structure is connected between the top of the screw rod and the power output end of the dual-axis motor.

[0032] A control unit and a data storage unit are provided in the docking charging unit 33. The data storage unit stores the corresponding coordinate information of each numbered energy storage unit in the energy storage container 1. The coordinate information includes the placement height of the energy storage unit and the horizontal straight-line distance relative to the docking charging unit 33 and the left and right direction relative to the docking charging unit 33. The control unit is connected to the dual-axis motor signal and is used to control the lifting guide rail 3 to drive the horizontal guide plate 32 to move to the placement height of the corresponding numbered energy storage unit. Specifically, a wireless communication module connected to the control unit is also provided in the docking charging unit 33. When the docking charging unit 33 is docked with the inspection robot, the wireless communication module establishes a wireless connection with the inspection robot. When multiple energy storage units at the same height complete data collection, the inspection robot sends the number information of the next energy storage unit to be inspected at a different height to the wireless communication module. At this time, the lifting guide rail 3 drives the horizontal guide plate 32 to adjust its position, so that the inspection robot continues to inspect. When setting the inspection path, the inspection order of each energy storage unit is arranged according to the energy storage unit positioning information, and the energy storage unit numbers at different heights are separated by identifiers. A suitable control unit and wireless communication module in the prior art are selected and set by those skilled in the art; An island operation module is provided in the energy storage management module, which supports 72-hour island operation of the energy storage management module. In the island operation state, the energy storage module calls the energy storage unit to maintain the operation of the inspection robot. When the inspection decision module plans the inspection path in the island operation state, a charging node is set. The charging node is located on the lifting guide rail 3 of the designated energy storage container 1; When the inspection robot is charging at the charging node, the inspection robot moves to the horizontal guide plate 32 and docks with the docking charging unit 33 .

[0033] The design of the lifting rail 3 enables the inspection robot to move smoothly and accurately in the vertical direction, greatly improving the inspection efficiency. The double-axis motor drives the screw to rotate, and the bracket on the screw drives the horizontal guide plate 32 to move up and down along the lifting frame 31, thereby realizing the rapid switching of the inspection robot between energy storage units at different heights. At the same time, the coordinated work of the docking charging unit 33 and the control unit ensures that the inspection robot can accurately dock and charge at the charging node, ensuring the continuous progress of the inspection task.

[0034] This embodiment realizes the flexible movement and automatic charging function of the inspection robot on the lifting guide rail 3, further improving the efficiency and accuracy of the inspection; this not only helps to timely discover and deal with potential safety hazards, but also optimizes the utilization of the energy storage unit.

[0035] In summary, this solution realizes efficient and intelligent management and maintenance of the energy storage power system. By introducing an auxiliary decision-making platform and combining real-time meteorological data and equipment status data, the system can dynamically adjust the inspection path and frequency to ensure that the inspection device can inspect the energy storage unit and related equipment stably and timely. At the same time, the design of the lifting guide rail 3 realizes the smooth movement and automatic charging of the inspection robot in the vertical direction, thereby improving the inspection efficiency.

[0036] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
