DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0021] Since in some technologies, when a fire occurs in a power distribution device, it is impossible to automatically extinguish the fire, in order to solve this technical problem, the present application provides a power distribution device, and the structures of the various parts of the power distribution device are described below: See also Figure 1 , Figure 2 , Figure 3The present application provides a power distribution device, including a cabinet 1, a mounting frame 2 is installed inside the cabinet 1, a plurality of standardized slots 3 are arranged on the mounting frame 2, and standardized modules 4 are respectively plugged into the plurality of standardized slots 3; a circuit is arranged in the mounting frame 2, a main cable 51 is connected to the circuit in the mounting frame 2, and after the connector 52 is plugged into the interface 53, the circuit in the mounting frame 2 is energized, the standardized module 4 can be set as a power module, a metering module, a protection module, a control module and a communication module, and the standardized module 4 is inserted into the standardized slot 3 to realize power-on, and the user can install different standardized modules 4 according to actual use requirements, and when different standardized modules 4 need to be replaced, the standardized module 4 to be replaced can be unplugged after power failure, and the required standardized module 4 can be inserted, which is convenient to operate and has high replacement efficiency. Through the setting of multiple standardized modules 4, the user can set multiple standardized modules 4 with different functions and different power connection specifications according to the use requirements, and under the condition that the power connection panel, the electric meter and the control panel need to be replaced frequently, the user can replace the standardized module 4 more conveniently and with high replacement efficiency, which saves the operation time and is also convenient for the fault inspection and repair of different standardized modules 4.

[0022] Furthermore, the power distribution equipment also includes a power-off component 5, which is used to disconnect the power supply when a fire occurs in the cabinet 1. The power-off component 5 includes a main cable 51, which is connected to the rear side of the mounting frame 2. The end of the main cable 51 away from the mounting frame 2 is connected to a connector 52, and an interface 53 is plugged into the connector 52. The outer wall of the interface 53 is connected to an outer disk 54, and the interface 53 is connected to an external power supply; the power-off component 5 also includes two counterweights 57, which are respectively slidably connected to both sides of the mounting frame 2, and the tops of the two counterweights 57 are respectively connected to pull ropes 56. A plurality of guide rods 59 are provided on the mounting frame 2, and the plurality of guide rods 59 guide the two pull ropes 56. See FIG. Figure 4 as well as Figure 5A fuse 55 is connected between the two pull ropes 56. The fuse 55 is located at the front side of the mounting frame 2. Under normal conditions, the fuse 55 pulls up the two counterweights 57 through the two pull ropes 56, so that the two counterweights 57 are suspended at the highest point. When a fire occurs in the cabinet 1, the fuse 55 gradually melts and breaks. After the fuse 55 breaks, the two counterweights 57 fall down. A frame 58 is connected between the two counterweights 57. The frame 58 is located at the rear of the mounting frame 2. The bottom surface of the frame 58 contacts the top surface of the outer plate 54. When 58 moves downward, the interface 53 is pulled downward through the outer disk 54, so that the interface 53 and the connector 52 are disconnected, thereby disconnecting the main cable 51 from the external power supply; through the setting of the power-off component 5, the two counterweights 57 can automatically fall when a fire occurs in the cabinet 1, and the connection between the connector 52 and the interface 53 is disconnected through the cooperation of the frame 58 and the outer disk 54, so that the main cable 51 is disconnected from the external power supply, thereby disconnecting the energy source, while also minimizing the impact on the external power supply and reducing losses.

[0023] In some embodiments, the fuse 55 includes a primary fuse and a secondary fuse. The primary fuse is a low melting point alloy, such as Wood's alloy, with a melting point of 70°C, connected in parallel to the temperature monitoring point of the main cable 51, and triggers an early warning by monitoring the temperature rise of the main cable joint. The primary fuse partially melts because the temperature reaches the melting point, but due to its parallel design, the main circuit remains conductive. The main circuit includes multiple main cable segments, such as: an incoming busbar, a main cable 51, a secondary fuse, a main cable 51, a circuit breaker, and an outgoing terminal.

[0024] For example, when the temperature at the place where the main cable 51 is connected to the incoming busbar is greater than 70°C, the primary fuse will melt and send an alarm signal.

[0025] The secondary fuse is a standard fuse with a melting point of 120°C. It is connected in series between the main cable 51 and the load to take on the task of power off in case of overload / short circuit. The current carrying capacity of the main cable 51 matches the rated current of the secondary fuse. For example, a cable of 50mm² corresponds to a fuse of 200A.

[0026] To achieve temperature detection, NTC (Negative Temperature Coefficient, thermistor) can also be set on the primary and secondary fuses with an accuracy of ±0.5°C.

[0027] In some embodiments, a controller is further included, and the controller is configured to receive data sent by the primary fuse and the secondary fuse, and issue a response based on data analysis. For example, if the temperature continues to rise to 120°C, the controller initiates a secondary response, forcibly disconnects the SSR, cuts off the main circuit, and blows the secondary fuse to ensure physical isolation, and records fault data (temperature curve, blow time).

[0028] When the fuse 55 is used for circuit protection, there is a certain reaction delay due to its fusing characteristics. This delay may cause the current to continue to flow before the fuse 55 melts, thereby causing more serious circuit damage, such as electrical fires, equipment damage, etc. Therefore, by introducing time delay control into the system, more accurate power-off can be achieved before the fuse 55 melts, thereby improving the protection effect.

[0029] When the current exceeds the rated safety current of the fuse 55, the metal wire inside the fuse 55 will melt due to overheating, thereby cutting off the circuit. However, there is a certain time delay in the melting process. When the current reaches the threshold of the fuse 55, the fuse 55 will not melt immediately, but will melt after a certain heating time until the temperature is high enough. Therefore, before the fuse 55 melts, the current may still flow, causing the circuit to be damaged by continuous high voltage or overcurrent.

[0030] In some embodiments, the controller is configured to: preset a time window, wherein the time window monitors current or temperature changes through a sensor, wherein the sensor can be a temperature sensor or a current sensor, and when an overload or short circuit is detected, a time delay timer is started, and the timer is set to start other control power-off procedures within a period of time before the fuse 55 is triggered.

[0031] By introducing time delay control, other power-off means, such as electronic switches or solid-state relays, can be used to disconnect the power supply in advance before the fuse 55 melts, thereby avoiding the risk caused by the delay of the fuse 55. During the time window, if it is detected that the current continues to exceed the set threshold (or the temperature is too high), the electronic switch (such as a solid-state relay, MOSFET, etc.) can quickly cut off the power supply before the fuse 55 melts, thereby preventing the current from continuing to flow and reducing potential damage.

[0032] In the process of coordinating the counterweight 57 with the fuse 55, a counterweight 57 that is too heavy or too light may cause a too fast or too slow reaction, and may not be able to cut off the power in time or cut off the power by mistake. Once the fuse 55 is triggered, it needs to be replaced, and the counterweight 57 may require the equipment to be disassembled and adjusted, which increases the difficulty of maintenance.

[0033] In some embodiments, a load sensor, such as a current sensor, a voltage sensor, or a temperature sensor, is provided to monitor the current and the load condition of the circuit. When the load changes or the current exceeds a set threshold, the sensor will output a signal to the controller. The controller receives the data from the sensor, processes the load information in real time, and determines whether the pressure or position of the counterweight 57 needs to be adjusted through a predetermined logic algorithm. The controller is used to send a control instruction to the drive device to adjust the counterweight 57.

[0034] Furthermore, the counterweight 57 is connected to a driving device, which is used to change the position or pressure of the counterweight 57, and the driving device can be an electric motor. The position of the counterweight 57 is accurately adjusted by the electric motor. For example, a servo motor and a screw transmission device, such as a lead screw, can be used to achieve displacement control. A linear slide rail, a lifting platform or a ball screw can also be provided to ensure the movement accuracy of the counterweight 57. The position of the counterweight 57 can be changed according to the instructions of the controller, thereby adjusting its triggering pressure on the fuse 55.

[0035] To ensure precise adjustment, the controller is also communicatively connected to a feedback device, which can monitor the position change of the counterweight 57 in real time and feed it back to the controller, and the feedback device includes a position sensor. Exemplarily, the current, temperature and other parameters are monitored by sensors, and the parameter data is input into the controller for real-time processing, that is, the change in current or temperature is compared with the preset threshold value to determine whether it is currently in the normal range, and the load fluctuation trend is analyzed according to the rate of change of real-time current, temperature or load. For instantaneous load surges (such as high current at the moment of startup), it is necessary to determine whether the load exceeds the safe range. If the load fluctuates violently in a short period of time (such as short circuit or sudden overload), take measures in advance to adjust the pressure or position of the counterweight 57 to ensure that the protection mechanism responds in time.

[0036] According to the change of load, the controller automatically changes the position of the counterweight 57 or the pressure applied by adjusting the driving device. When the load increases, if the current or temperature exceeds the preset value, the controller will send an instruction to the driving device to adjust the position of the counterweight 57 so that it applies greater pressure or triggers the fuse 55 more directly, thereby cutting off the current earlier.

[0037] When the load is reduced, if the load is reduced, the pressure can be reduced by adjusting the position of the counterweight 57 to prevent excessive triggering of the protection. The position and pressure of the counterweight 57 are adjusted to ensure precise control through a feedback device. For example, a position sensor is used to feedback the specific position of the counterweight 57. The controller can also adjust the output of the electric motor according to the feedback data to ensure that the counterweight 57 accurately reaches the required position and pressure value.

[0038] In order to predict the possibility of fire occurrence, in some embodiments, the controller is further configured to: Acquiring data of the load sensor, the data including at least temperature data, humidity data and oxygen concentration data; Pre-trained LSTM (Long Short Term Memory) model; The data of the load sensor is input into the pre-trained LSTM model to predict the probability value of the fire risk based on the LSTM model.

[0039] LSTM is used to process time series data and can retain information over a long time span. LSTM is suitable for analyzing and predicting time-related changing trends and fire prediction. It can predict the probability of fire by analyzing environmental factors, such as the changing trends of temperature, humidity, oxygen concentration and other data.

[0040] For temperature data, high temperatures occur after a fire occurs. By monitoring temperature changes, LSTM can identify abnormal temperature rise trends. For humidity data, changes in humidity affect the spread of a fire. When a fire occurs, humidity changes. For oxygen concentration data, the combustion process of a fire consumes oxygen. Oxygen concentration is used to determine whether there is a potential fire source.

[0041] For example, if the oxygen concentration continues to drop over a period of time, it means that the fire will consume oxygen and a certain area is burning. The LSTM model can identify the fire situation through this change trend. For another example, if the temperature rises sharply in a short period of time, the LSTM may recognize that this is a precursor to a fire. By combining other environmental parameters, the LSTM model can give an early warning.

[0042] Further, see Figure 6 as well as Figure 7 The power distribution equipment also includes a fire extinguishing assembly 6, which is used to extinguish a fire when a fire occurs in the cabinet 1. The fire extinguishing assembly 6 includes two fire extinguishers 61, which are respectively installed on both sides of the mounting frame 2 through clamps. The two fire extinguishers 61 are respectively located in front of the two counterweights 57. Supports 64 are respectively connected to the two sides of the mounting frame 2. A pressure rod 65 is rotatably connected to the support 64. A pull rod 63 is hinged on the top of the counterweight 57. The ends of the two pull rods 63 away from the counterweight 57 are respectively hinged to the ends of the two pressure rods 65 away from the supports 64. A pressure handle switch 62 is provided on the top of the fire extinguisher 61. The two pressure rods 65 are respectively located above the two pressure handle switches 62. When the two pressure rods 65 move, they are respectively connected to the two When the counterweight 57 falls, the pressure rod 65 is pulled down through the pull rod 63, so that the pressure rod 65 swings downward with the support 64 as the center of the circle. When the pressure rod 65 swings downward, it contacts the pressure handle switch 62 and squeezes it downward. After the pressure handle switch 62 is squeezed, the fire extinguisher 61 is turned on, so that the two fire extinguishers 61 spray out the fire extinguishing agent at the same time, and the fire extinguishing agent covers the front side of the mounting frame 2 and the inner wall of the cabinet 1, thereby extinguishing the fire source; two groups of spring pieces 67 are respectively connected to the two sides of the mounting frame 2, and one group of spring pieces 67 is provided with a plurality of spring pieces, and the plurality of spring pieces 67 have a certain elastic force. Two mounting plates 68 are respectively connected to the two groups of spring pieces 67, and the mounting plates 68 are located between the fire extinguisher 61 and the counterweight 57. Figure 8, a plurality of touch balls 610 are connected to the side of the mounting plate 68 facing the fire extinguisher 61, and a sawtooth groove frame 69 is connected to the side of the mounting plate 68 facing the counterweight block 57. A sliding shaft 66 is connected to the counterweight block 57, and a sawtooth groove frame 69 is provided with a sawtooth groove. The sliding shaft 66 is in sliding contact with the sawtooth groove of the sawtooth groove frame 69, and the sliding shaft 66 is driven to move downward when the counterweight block 57 falls. When the sliding shaft 66 moves downward, it slides down along the sawtooth groove of the sawtooth groove frame 69, so that the sawtooth groove frame 69 is continuously moved backward by the reverse thrust of the sliding shaft 66 and then rebounds forward by the elastic force of a group of spring pieces 67. The plurality of touch balls 610 on the mounting plate 68 are set as one group, and the two groups of touch balls 610 are in contact with the two fire extinguishers 61 respectively during movement. When the mounting plate 68 rebounds forward, it drives the plurality of touch balls 610 to move forward, so that the plurality of touch balls 610 hit the fire extinguisher 61, when the two fire extinguishers 61 are turned on, the two groups of touch balls 610 respectively strike the two fire extinguishers 61 for multiple times, so that the two fire extinguishers 61 vibrate with a certain amplitude, achieving the effect of slight shaking, thereby shaking the fire extinguishing agent inside evenly to ensure the use effect. The fire extinguisher 61 is set separately and is not connected to other structures under normal circumstances, which is convenient for regular replacement; through the setting of the fire extinguishing component 6, after a fire occurs in the cabinet 1, the two fire extinguishers 61 can automatically spray the fire extinguishing agent to put out the fire source in time and prevent the fire from spreading; through the setting of the two groups of touch balls 610, the two groups of touch balls 610 can respectively knock the two fire extinguishers 61 for multiple times, so that the fire extinguishers 61 vibrate, thereby vibrating the fire extinguishing agent inside evenly, avoiding the phenomenon that some fire extinguishing agents are left standing for a long time and precipitate and agglomerate, thereby affecting the use effect.

[0043] Since the internal structure of the power distribution equipment is relatively compact, in order to make the fire extinguishing agent inside the fire extinguisher 61 more evenly distributed and improve the fire extinguishing effect, in some embodiments, a vibration device is provided in the touch ball 610, and the vibration device includes a piezoelectric element, an electrode, and a vibration transmission structure. The piezoelectric element is a ceramic material. The piezoelectric element is used to convert the electrical signal into mechanical vibration. It can be a thin sheet or a cylindrical shape. The electrode is connected to the two ends of the piezoelectric element. When the voltage is applied, the piezoelectric element is deformed by the electric field. The electrode is a conductive material, for example, a metal or a conductive coating. The vibration transmission structure is used to transmit the mechanical vibration generated by the piezoelectric element to the inside of the fire extinguisher 61 to ensure that the vibration effectively affects the distribution of the fire extinguishing agent. The vibration can be transmitted to the inside of the fire extinguisher 61 by directly connecting the piezoelectric element to the container wall inside the fire extinguisher 61, or by an elastic material (such as a spring, a rubber pad).

[0044] The controller is used to apply appropriate electrical signals to the piezoelectric element to adjust the vibration frequency and amplitude. The required voltage and frequency can be generated by a microcontroller, oscillator and amplifier.

[0045] Exemplarily, a voltage is applied to both ends of the piezoelectric element to stimulate its deformation, and the applied voltage waveform and amplitude determine the vibration frequency and amplitude of the piezoelectric ceramic. By adjusting the frequency and amplitude in the circuit, the intensity of the vibration can be controlled. When the piezoelectric ceramic is deformed, periodic small displacements will occur, and these displacements will be converted into mechanical vibrations through the connection with the inner wall of the fire extinguisher 61 (such as an elastic structure or a bracket), vibrating the fire extinguishing agent. These vibrations will propagate inside the fire extinguisher 61, so that the fire extinguishing agent will not precipitate or agglomerate during storage, and will be evenly sprayed out when triggered, thereby improving the fire extinguishing effect.

[0046] To ensure the uniformity of the extinguishing agent, the vibration frequency and amplitude need to be precisely controlled according to the type of extinguishing agent (powder, liquid, etc.).

[0047] In order to further improve the fire extinguishing efficiency and reduce the probability of the fire source re-igniting, in some embodiments, the power distribution equipment also includes an inert gas storage tank, a gas control valve, a regulating device, a gas delivery pipeline, and a nozzle.

[0048] Inert gas storage tanks are used to store inert gases, such as nitrogen and carbon dioxide. It is understood that the gas can be compressed gas or liquid gas, which is converted into a gas state through a gas booster system. The material of the gas storage tank is a high-pressure resistant metal material, such as aluminum alloy or stainless steel, to ensure safety under high pressure.

[0049] The gas control valve and the regulating device are used to control the release and flow of the inert gas. The regulating device can be automatically opened after the fire is extinguished, or opened upon receiving an instruction to continuously release the inert gas. The gas control valve can control the time and flow of the gas release. The gas control valve is linked to the load sensor of the fire extinguisher 61 and automatically starts after the flame is extinguished for a preset time.

[0050] In some embodiments, the controller is configured to: The time when the fire extinguisher 61 is activated is obtained, and after a preset time, an instruction is sent to the regulating device and the gas control valve to start controlling the gas regulating valve to release the inert gas.

[0051] For example, after the fire extinguishing agent is sprayed, the fire source has been extinguished, but to prevent re-ignition, the inert gas storage tank is automatically opened through the gas control valve, and nitrogen is continuously sprayed into the fire extinguisher 61 through the gas pipeline and nozzle to reduce the oxygen concentration, further ensure the lack of oxygen around the fire source, and prevent re-ignition. When the temperature and gas concentration inside the fire extinguisher 61 are stable, the gas control valve is automatically closed to end the fire extinguishing process.

[0052] In order to control the activation strength and vibration effect of the fire extinguisher 61, in some embodiments, a release assembly is further provided, the release assembly includes a motor, a spring and a release slot, the spring can slide in the release slot, and one end of the spring is connected to the counterweight 57 through the release slot. When the spring receives the force from the motor, the counterweight 57 is pushed downward through the release slot.

[0053] The force of the spring is transmitted to the counterweight 57 through the release slot, generating a linear driving force, causing the counterweight 57 to slide downward and release, thereby making the movement of the counterweight 57 smoother and avoiding sudden impact force, while also enabling more precise control of the preload force and compression degree of the spring.

[0054] In different fire situations, the elastic force during triggering can be adjusted to make the release speed of the counterweight 57 more precise. For example, the force of the spring can be adjusted according to the ambient temperature, fire type or fire severity, so that the counterweight 57 is released at different speeds, thereby affecting the activation strength and vibration effect of the fire extinguisher 61.

[0055] For example, the fire type or fire severity can be detected by a temperature sensor. When the temperature exceeds a set threshold, it indicates that the fire intensity is large, and the preload force of the spring can be automatically increased to accelerate the activation of the fire extinguisher 61.

[0056] In order to cooperate with the spring, in some embodiments, the tooth angle or pitch density of the sawtooth slot frame 69 is adjustable. The sawtooth slot frame 69 includes a sawtooth slot frame body, a sliding slot frame, a tooth profile adjustment device and a driver. The sawtooth slot frame body is provided with a sawtooth slot inside. The tooth profile can be designed to be rectangular, trapezoidal or arc-shaped, etc., and can be set by sliding friction characteristics. The gap between the teeth is the tooth pitch, which can be increased or decreased by the tooth profile adjustment device.

[0057] The sliding slot frame can be a sliding bar or a sliding plate, which can move forward and backward in the slot frame to change the tooth pitch. The tooth profile adjustment device can be an electric slider or a tooth pitch adjustment wheel, which can be adjusted by a driver to change the distance between teeth. The driver can drive a screw mechanism to push the sliding bar or the tooth pitch adjustment wheel through the rotation of the screw to change the gap of the tooth profile.

[0058] Exemplarily, based on the control signal sent by the controller, a driver, such as a stepper motor or a servo motor, starts working, the motor drives the screw, pushes the sliding bar or the tooth adjustment device in the slot frame, changes the gap between the teeth in the tooth frame, and according to the intensity of the fire, the driver can automatically increase or decrease the pitch to adjust the resistance so that the fire extinguisher 61 can be started at an appropriate speed.

[0059] In order to achieve better starting strength and vibration effect, the tension of the spring and the pitch of the sawtooth slot frame 69 can be precisely controlled by joint adjustment, and the tension and pitch of the spring can be automatically adjusted according to the monitored fire intensity parameters. For example, when the fire intensity increases, the spring tension increases, and the pitch also increases, so that the counterweight 57 can be quickly released and the fire can be extinguished quickly; when the fire intensity is low, the tension and pitch are reduced to make the fire extinguisher 61 react more smoothly. Furthermore, the power distribution equipment also includes a sealing component 7, which is used to isolate air circulation when a fire occurs in the cabinet 1, see Fig. 9 , Fig.10 , Fig.11 , Fig.12 as well as Fig.13 The sealing assembly 7 includes a ventilation window 71, which is installed on the rear side of the cabinet 1. The ventilation window 71 is provided with a plurality of ventilation slots. The plurality of ventilation slots of the ventilation window 71 are respectively slidably connected with sealing slide bars 75. The sealing assembly 7 also includes a light rod 73. The two ends of the light rod 73 are respectively connected with connecting rods 74. The rear side of the connecting rod 74 is connected with a plurality of connecting pieces 76. The plurality of connecting pieces 76 of the two connecting rods 74 are respectively connected with the two ends of the plurality of sealing slide bars 75. The bottom of the frame frame 58 is connected with two slide slot frames 72. The slide slot frames 72 are provided with The slide groove, one part of the slide groove on the slide groove frame 72 is set as an inclined groove, and the light rod 73 is slidably connected with the slide grooves of the two slide groove frames 72. When the two slide groove frames 72 move down, the light rod 73 slides along the two slide grooves and is moved forward a certain distance by the inclined groove in the slide groove. When the light rod 73 moves forward, it drives the two connecting rods 74 to move forward. When the two connecting rods 74 move forward, they drive multiple sealing slide rods 75 to move forward through multiple connecting pieces 76. The bottom edge of the ventilation groove of the ventilation window 71 is set as an inclined surface, and the top edge of the sealing slide rod 75 is set as an inclined surface. The inclined surface of the sealing slide bar 75 and the inclined surface of the ventilation slot are in sliding contact. The sliding connection between the sealing slide bar 75 and the ventilation slot is inclined. The two connecting rods 74 are located in front of the ventilation window 71, and the plurality of sealing slide bars 75 are located on the rear side of the ventilation window 71. When the sealing slide bar 75 moves forward, the inclined surface of the top edge of the sealing slide bar 75 slides forward along the inclined surface of the bottom edge of the ventilation slot, so that the sealing slide bar 75 moves forward obliquely downward. Finally, the sealing slide bar 75 enters the ventilation slot to block the ventilation slot, thereby isolating the interior of the cabinet 1 from the external air. The cabinet 1 is airtightly isolated to prevent external air from entering the interior of the cabinet 1 and cut off the oxygen source. The cabinet 1 uses the negative pressure principle to tightly adsorb multiple sealing slide bars 75 on multiple ventilation slots to further optimize the sealing effect. Through the setting of the sealing component 7, the multiple sealing slide bars 75 on the ventilation window 71 can automatically block the multiple ventilation slots, thereby isolating the external air of the cabinet 1 and blocking oxygen from entering the cabinet 1. The fire extinguishing process is promoted by isolating oxygen, and at the same time, it can also prevent the fire from re-igniting when it comes into contact with oxygen after the fire source is extinguished.

[0060] In order to make the fire extinguisher 61 work more stably, the state of the fire extinguisher 61 equipment can be detected by the autoencoder. The autoencoder is an unsupervised learning model for anomaly detection. It learns the low-dimensional representation of the data, that is, compresses the data, and reconstructs it through the decoder. The model evaluates whether the data is abnormal through the reconstruction error. The autoencoder can detect potential problems of the fire extinguisher 61, such as gas leakage, insufficient pressure, sensor failure, etc.

[0061] The autoencoder consists of an encoder and a decoder. The encoder compresses the input data into a lower-dimensional representation, and the decoder reconstructs the original data based on the low-dimensional representation. The autoencoder learns the normal pattern of the data by minimizing the reconstruction error.

[0062] When the state of the fire extinguisher 61 deviates greatly from the normal state in the training data, the reconstruction error of the autoencoder will increase significantly. Based on the reconstruction error, the autoencoder can detect the abnormal condition of the fire extinguisher 61.

[0063] In some embodiments, the controller is configured to: Acquire status data of the fire extinguisher 61, wherein the status data includes gas pressure, gas storage amount, temperature, battery power, and sensor data; Train the autoencoder model; Inputting the state data into a trained autoencoder model to output reconstructed data generated by a decoder through the autoencoder model, and calculating a reconstruction error; If the reconstruction error is greater than or equal to the error threshold, a warning instruction is generated, where the warning instruction is used to indicate that the state of the fire extinguisher 61 is abnormal.

[0064] For abnormal status, if the gas storage capacity of the fire extinguisher 61 drops beyond the preset range, the reconstruction error of the autoencoder is greater than or equal to the error threshold, and the fire extinguisher 61 may leak. If the internal pressure of the device is lower than the normal range, the decoder cannot correctly reconstruct the state, and then generates an early warning instruction.

[0065] With the above structure, the working principle of the present application is as follows: a circuit is provided in the mounting frame 2, the main cable 51 is connected to the circuit in the mounting frame 2, and after the connector 52 is plugged into the interface 53, the circuit in the mounting frame 2 is energized, and the standardized module 4 can be set as a power module, a metering module, a protection module, a control module and a communication module. The standardized module 4 is inserted into the standardized slot 3 to realize power-on. The user can install different standardized modules 4 according to actual use requirements. When different standardized modules 4 need to be replaced, the standardized module 4 to be replaced can be unplugged after power failure, and the required standardized module 4 can be inserted. The operation is convenient and the replacement efficiency is high. Through the setting of multiple standardized modules 4, the user can set multiple standardized modules 4 with different functions and different power connection specifications according to the use requirements. Under the working conditions where the power connection panel, the electric meter and the control panel need to be replaced frequently, the user can replace the standardized module 4 more conveniently and with high replacement efficiency, which saves the operation time and is also convenient for the fault inspection and repair of different standardized modules 4.

[0066] Since there are many electronic components and combustibles on the front side of the mounting frame 2 and the front side of the plurality of standardized modules 4, the fire position is usually located on the front side of the mounting frame 2. When a fire occurs in the cabinet 1, the fuse 55 gradually melts and breaks. Under normal conditions, the fuse 55 pulls up the two counterweights 57 through the two pull ropes 56, so that the two counterweights 57 are suspended at the highest point. When the fuse 55 breaks, the two counterweights 57 fall down, and the two counterweights 57 drive the frame 58 to move downward when they fall. Under normal conditions, the frame 58 is against the top of the outer plate 54. When the frame 58 moves downward, the interface 53 is pulled downward through the outer disk 54, so that the interface 53 and the connector 52 are disconnected, thereby disconnecting the main cable 51 from the external power supply; through the setting of the power-off component 5, the two counterweights 57 can automatically fall when a fire occurs in the cabinet 1, and the connection between the connector 52 and the interface 53 is disconnected through the cooperation of the frame 58 and the outer disk 54, so that the main cable 51 is disconnected from the external power supply, thereby disconnecting the energy source, while also minimizing the impact on the external power supply and reducing losses.

[0067] Taking one of the fire extinguishers 61 as an example, when the counterweight block 57 falls, the pressure rod 65 is pulled down by the pull rod 63, so that the pressure rod 65 swings downward with the support 64 as the center of the circle. When the pressure rod 65 swings downward, it contacts the pressure handle switch 62 and squeezes it downward. After the pressure handle switch 62 is squeezed, the fire extinguisher 61 is turned on, so that the two fire extinguishers 61 spray out the fire extinguishing agent at the same time, and the fire extinguishing agent covers the front side of the mounting frame 2 and the inner wall of the cabinet 1, thereby extinguishing the fire source; when the counterweight block 57 falls, it drives the sliding shaft 66 to move downward, the sawtooth groove frame 69 and the mounting plate 68 form a whole, and the multiple spring pieces 67 have a certain elastic force. When the sliding shaft 66 moves downward, it slides down along the sawtooth groove of the sawtooth groove frame 69, so that the sawtooth groove frame 69 is continuously moved backward by the reverse thrust of the sliding shaft 66, and then rebounds forward by the elastic force of a group of spring pieces 67, and the mounting plate 68 drives the multiple touch balls 610 forward when rebounding forward. Move, so that multiple touch balls 610 hit the fire extinguisher 61, so that when the two fire extinguishers 61 are turned on, the two groups of touch balls 610 respectively hit the two fire extinguishers 61 multiple times, so that the two fire extinguishers 61 produce a certain amplitude of vibration, achieving the effect of slight shaking, so that the fire extinguishing agent inside is shaken evenly to ensure the use effect. The fire extinguisher 61 is set separately and is not connected to other structures under normal circumstances, which is convenient for regular replacement; through the setting of the fire extinguishing component 6, after a fire occurs in the cabinet 1, the two fire extinguishers 61 can automatically spray the fire extinguishing agent to put out the fire source in time and prevent the fire from spreading; through the setting of the two groups of touch balls 610, the two groups of touch balls 610 can respectively knock on the two fire extinguishers 61 multiple times, so that the fire extinguisher 61 produces vibration, thereby vibrating the fire extinguishing agent inside evenly, avoiding the phenomenon that some fire extinguishing agents are left to stand for a long time and precipitate and agglomerate, thereby affecting the use effect.

[0068] The ventilation window 71 and the multiple ventilation slots above it play a ventilation role, which is convenient for heat dissipation in the cabinet 1. Under normal circumstances, the multiple sealing slide bars 75 are respectively located above the rear sides of the multiple ventilation slots, and do not affect the ventilation area of ​​the ventilation slots. When the frame frame 58 moves down, the frame frame 58 drives the two slide slot frames 72 to move down. One part of the slide slot on the slide slot frame 72 is set as an inclined slot. Therefore, when the two slide slot frames 72 move down, the light rod 73 is moved forward a certain distance when it slides along the two slide slots. When the light rod 73 moves forward, it drives the two connecting rods 74 to move forward. When the two connecting rods 74 move forward, they drive the multiple sealing slide bars 75 to move forward through the multiple connecting pieces 76. The inclination angle set at the sliding connection between the sealing slide bar 75 and the ventilation slot is the same as the angle of the inclined surface of the sealing slide bar 75. Therefore, when the sealing slide bar 75 moves forward, the inclined surface of the top edge of the sealing slide bar 75 follows the bottom edge of the ventilation slot. The inclined surface slides forward, causing the sealing slide bar 75 to move forward and obliquely downward. Finally, the sealing slide bar 75 enters the ventilation slot and blocks the ventilation slot, thereby isolating the interior of the cabinet 1 from the outside air, preventing the outside air from entering the interior of the cabinet 1 and cutting off the oxygen source. The maximum height of the sealing slide bar 75 is higher than the height of the actual ventilation area of ​​the ventilation slot, and the sealing slide bar 75 is located on the rear side of the ventilation slot. Therefore, when the air pressure in the cabinet 1 is lower than that of the outside air, the cabinet 1 uses the negative pressure principle to tightly adsorb multiple sealing slide bars 75 on multiple ventilation slots, further optimizing the sealing effect; through the setting of the sealing component 7, the multiple sealing slide bars 75 on the ventilation window 71 can automatically block multiple ventilation slots, thereby isolating the outside air of the cabinet 1 and blocking the oxygen from entering the cabinet 1. The fire extinguishing process is promoted by isolating oxygen, and it can also prevent the fire from re-igniting when it subsequently contacts oxygen after the fire source is extinguished.
