One end of the two groups of support rods 113 is movably penetrated to the outside of the two vertical pull rods 218. The bottom of the fixed frame 201 is fixedly installed on the top of the mobile box 101 near the rear surface. The inside of the fault diagnosis instrument body 102 is sequentially provided with a data collector 103, a data processor 104, a diagnosis controller 105, a wireless communication device 106 and an alarm 107. The top of the fault diagnosis instrument body 102 is bolted with an inspection door 108. The front surface of the mobile box 101 is bolted with a mounting door 109. The rear surface of the mobile box 101 is fixedly installed with a mounting frame 110. The outer surface of the mounting frame 110 is movably provided with a telescopic push-pull rod 111.

[0037] In this embodiment, when in use, the forward and reverse motors 216 and the operation controller 219 are electrically connected, and a universal wheel is provided at the bottom of the mobile box 101. Figure 1As shown, the mobile box 101 is convenient to move. The outer surface of the mounting frame 110 is movably provided with a telescopic push-pull rod 111. The telescopic push-pull rod 111 can be expanded and retracted. By pulling the telescopic push-pull rod 111 to expand, the entire device can be pulled to move, which is convenient for moving the device to other energy storage devices for fault detection, and is relatively portable. Threaded holes are provided on the outer surfaces of both sides of the mobile box 101 near the front surface and the rear surface. Screws are threadedly embedded in the two threaded holes located at the rear position, and the two vertical pull rods 218 are fixed by two screws.

When the mobile diagnostic component 1 needs to work outdoors for a long time, in order to avoid long-term sunlight exposure to the top of the equipment, first remove the two screws, then start the forward and reverse motor 216 by operating the controller 219, and drive the first winding rod 203 to rotate through the output end of the forward and reverse motor 216, and drive the two first bevel gears 205 to rotate, and then drive the two second bevel gears 206 to rotate, and drive the two first gears 208 to rotate together through the two T-shaped shafts 207, so that the two chains 209 rotate in the same direction in the corresponding movable holes 213 respectively, and drive the two second gears 210 and the two second winding rods 211 to rotate in the same direction at the same time, thereby driving the three protective curtains 204 to rotate together, The three protective curtains 204 are lowered and the horizontal pull rod 217 is pulled forward at the same time, driving the two vertical pull rods 218 to move forward in the two slide grooves 112, pulling the released protective curtains 204 forward and gradually spreading them on the top and both sides of the fault diagnosis instrument body 102. When the protective curtains 204 are spread to the front upper part of the control screen in front of the fault diagnosis instrument body 102, the forward and reverse motors 216 are turned off, and then the screw is screwed in again to fix the moved vertical pull rods 218, so that the protective curtains 204 are pulled and unfolded, covering the top and both sides of the fault diagnosis instrument body 102, forming a sunshade to protect against sunlight and prevent the sunlight from directly shining on the top surface of the fault diagnosis instrument for a long time. A self-cleaning coating 2042 is sprayed on the outer surface of one side of the curtain 2041 in the protective curtain 204. The self-cleaning coating 2042 uses a coating containing nano titanium dioxide. Under sunlight, the nano titanium dioxide can produce a photocatalytic reaction to decompose organic matter, so that pollutants such as dust and oil on the surface of the curtain 2041 can be automatically decomposed to keep the protective curtain 204 clean. A heat-insulating coating 2043 is sprayed on the other side of the curtain 2041. The heat-insulating coating 2043 uses a ceramic micro-bead coating. The ceramic micro-bead has the characteristic of low thermal conductivity. When sunlight shines on the curtain 2041, the ceramic micro-bead heat-insulating coating can effectively block the transfer of heat.It can reflect most of the solar heat radiation, reduce the heat transmitted through the curtain 2041 to the fault diagnosis instrument body 102 below, and facilitate the fault diagnosis instrument body 102 to work better. A metal conductive coating 2044 is sprayed on one side of the thermal insulation coating 2043. The metal conductive paint is used. The metal conductive paint can form a structure similar to a Faraday cage. When there is external electromagnetic interference, the electromagnetic interference wave will generate an induced current on its surface when encountering the metal conductive coating 2044. This induced current will generate a reverse magnetic field, thereby offsetting the external electromagnetic interference, which helps the diagnostic instrument to accurately diagnose faults. It solves the problem that when the portable fault diagnosis instrument works outdoors for a long time, the outdoor sunlight will shine on the top of the fault diagnosis instrument for a long time, which may easily cause the temperature of the diagnostic instrument to be too high, affecting the internal electronic components, thereby affecting the diagnostic effect of the fault diagnosis instrument.

[0039] In this embodiment, when in use, the fault detection unit 3 monitors the status of each part of the energy storage operation and maintenance device in real time through sensors, collects the operating data of the energy storage system, and then transmits the operating data to the data acquisition unit 4. The data acquisition unit 4 collects various operating parameters and status information collected by the fault detection unit 3, and provides raw data support for subsequent fault diagnosis. The data preprocessing unit 5 performs preliminary processing on the data collected by the data acquisition unit 4, filters and denoises the data, removes abnormal values, and normalizes or standardizes the data, so that the data has better quality and consistency, which is convenient for subsequent units to perform effective analysis. The feature extraction unit 6 extracts key information that can reflect the operating status and fault characteristics of the energy storage system from the preprocessed data. These feature information is an important basis for judging whether the system has a fault and the type of fault. The rule engine module 701 in the fault diagnosis reasoning unit 7 stores and manages fault diagnosis rules. When receiving relevant information data, it makes judgments according to the rule logic. It provides an intuitive, knowledge-based diagnosis method for fault diagnosis, so that the diagnosis process can be carried out according to clear standards. The model building module 702 is responsible for building various mathematical models or physical models of the energy storage system to help predict the operating state of the energy storage system under normal conditions. By comparing the actual operating data with the model prediction data, potential faults can be discovered. The model building module 702 is based on the model diagnosis method and can deeply analyze the relationship between the internal state change of the system and the fault. The machine learning module 703 includes a variety of machine learning algorithms, such as support vector machine (SVM), neural network, decision tree, etc. The main function of this module is to use a large amount of historical fault data and normal operation data to train the machine learning model. The real-time collected data is input into the trained machine learning model, and the model can output the fault probability, fault type and other diagnostic results. The result evaluation module 704 evaluates and verifies the results of the fault diagnosis reasoning. When the rule engine module 701, the model building module 702 and the machine learning module 703 cooperate to obtain the fault diagnosis result, the result evaluation module 704 will judge the reliability of the result according to certain standards, and then transmit the diagnosis result to the fault alarm unit 8, the fault recording unit 9 and the human-computer interaction unit 10 through the data interface module 705. The fault alarm unit 8 sends an alarm signal to remind the operation and maintenance personnel. The fault recording unit 9 records the time, type, and related parameters of the fault, so as to facilitate subsequent query and analysis of the cause of the fault. The human-computer interaction unit 10 allows operation and maintenance personnel to view the real-time operation data, fault diagnosis results, historical fault records, and other information of the system through the interface, and can also set parameters for the system, control the start and stop of the diagnosis process, and other operations. The communication unit 11 realizes the information exchange between the fault diagnosis system and external devices, uploads the collected data, diagnosis results, and other information to the remote monitoring center, and can also receive control instructions from the remote monitoring center.

[0040] The effect and working principle of the whole mechanism are as follows: remove the two screw rods, then start the forward and reverse motor 216, drive the first winding rod 203 and the two first bevel gears 205 to rotate, then drive the two second bevel gears 206 to rotate, and drive the two first gears 208 to rotate together through the two T-shaped shafts 207, so that the two chains 209 rotate in the same direction in the corresponding movable holes 213, respectively, drive the two second gears 210 and the two second winding rods 211 to rotate in the same direction at the same time, thereby driving the three protective curtains 204 to rotate together, perform the curtain release operation, and at the same time pull the horizontal pull rod 217 forward to move The two vertical pull rods 218 are driven to move forward in the two slide grooves 112, and the released protective curtain 204 is pulled forward and gradually spread on the top and both sides of the fault diagnosis instrument body 102. When the protective curtain 204 is spread to the front upper part of the control screen in front of the fault diagnosis instrument body 102, the forward and reverse motors 216 are turned off, and then the screw is screwed in again to fix the moved vertical pull rods 218, so that the protective curtain 204 is pulled and spread, and covers the top and both sides of the fault diagnosis instrument body 102 to form a sunshade to protect the sunlight and prevent the sunlight from directly irradiating the top surface of the fault diagnosis instrument for a long time. The self-cleaning coating 2042 uses a coating containing nano titanium dioxide. Under sunlight, the nano titanium dioxide can produce a photocatalytic reaction to decompose organic matter, so that the dust, oil and other pollutants on the surface of the curtain 2041 can be automatically decomposed to keep the protective curtain 204 clean. The thermal insulation coating 2043 uses a ceramic microbead coating. The ceramic microbead has the characteristics of low thermal conductivity and can effectively block the transfer of heat. The metal conductive coating 2044 uses metal conductive paint to form a structure similar to a Faraday cage, which offsets external electromagnetic interference and helps the diagnostic instrument to accurately diagnose faults. The data acquisition unit 4 uses the fault detection unit 3 to collect the operating parameters of the energy storage system in real time and continuously. The data preprocessing unit 5 receives the collected data, filters it, and removes high-frequency noise and interference signals.

The rule engine module 701 matches the received feature data with the pre-stored fault diagnosis rules. The energy storage system model constructed by the model construction module 702 will make predictions based on the input operating parameters. The machine learning module 703 processes the input feature data. For the trained neural network model, the feature data will be propagated and calculated between the neurons of each layer of the neural network to obtain the results of the fault probability or fault type. When the rule engine module 701, the model building module 702 and the machine learning module 703 cooperate to obtain the fault diagnosis result, the result evaluation module 704 considers the rationality of the diagnosis result, and then transmits the diagnosis result to the fault alarm unit 8, the fault recording unit 9 and the human-computer interaction unit 10 through the data interface module 705. The fault alarm unit 8 sends an alarm signal to remind the operation and maintenance personnel.The fault recording unit 9 records the time, type, and related parameters of the fault. The human-computer interaction unit 10 allows maintenance personnel to view the real-time operation data, fault diagnosis results, and historical fault records of the system through the interface. They can also set system parameters, start and stop the control diagnosis process, and other operations. The communication unit 11 realizes information exchange between the fault diagnosis system and external devices.
