Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically to a charging pile monitoring device and monitoring method. Background Technology

[0002] Current charging pile monitoring equipment is crucial for real-time monitoring of the status of charging piles and charging vehicles, aiming to ensure the safety and stability of the charging process. However, existing monitoring equipment exhibits a certain lag in fire detection when a vehicle or charging pile catches fire. Due to technological limitations, the monitoring equipment cannot promptly and accurately identify early signs of a fire, such as localized temperature increases and the initial formation of flames. This results in the inability to issue alarms and activate corresponding fire-fighting mechanisms immediately after a fire breaks out, thus delaying the optimal time for fire suppression. Secondly, the linkage between monitoring equipment and fire-fighting systems is not close or efficient enough. When the monitoring equipment detects a fire signal, it cannot extinguish the fire in time, leading to the fire intensifying. An intensified fire means that the vehicle itself, the charging pile, and surrounding facilities may suffer more severe damage. Electric vehicles may be completely burned, the expensive equipment of the charging pile may be rendered unusable, and surrounding buildings, power lines, and other facilities may also be affected, causing huge economic losses. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a charging pile monitoring device and method. By setting up a fire extinguishing drive mechanism, it can accurately extinguish fires at the location of vehicle fires during the charging process. By setting up a closed fireproof mechanism, it can quickly seal off the charging pile when a vehicle catches fire, preventing the fire from spreading to the charging pile.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a charging pile monitoring device, comprising: a pre-embedded base frame, a dry powder box, and a pole. The dry powder box is installed behind the pre-embedded base frame, and the pole is installed above the dry powder box. A fire extinguishing drive mechanism is provided above the pole. The fire extinguishing drive mechanism includes a top crossbar, a side sliding groove, and a moving frame. A side sliding groove is provided on each of the left and right sides of the top crossbar. A moving frame is provided above the top crossbar. A drive motor is installed on the right side inside the moving frame. A motor one is installed on the left side of the moving frame.

[0008] During the entire vehicle charging process, three temperature sensors can detect the temperature at different locations around the vehicle. When the vehicle temperature detected by these three temperature sensors is higher than the preset normal threshold, the data acquisition module transmits these temperature data to the recognition module. After receiving the data, the recognition module will conduct an in-depth and comprehensive analysis. It will carefully compare the current temperature data with the normal range, and consider the factors affecting the rate and duration of temperature change. Once the analysis results indicate that the temperature is abnormal, the recognition module will generate a high-temperature electrical signal and transmit this important electrical signal to the cloud system through the central control module. After receiving the electrical signal, the cloud system will promptly issue a temperature alarm reminder to relevant personnel.

[0009] The three front flame sensors can detect light or radiation of specific wavelengths produced by flames to determine whether a flame exists and detect whether the vehicle and charging station catch fire during the charging process. The data acquisition module detects whether the vehicle catches fire during the charging process and transmits the collected data to the identification module. The identification module performs in-depth identification. If the vehicle catches fire, the identification module transmits an electrical signal to the central control module and sends a fire alarm signal to the cloud.

[0010] Preferably, a closed fireproof mechanism is provided behind the upright, which includes a fixed connecting rod, a top plate, an embedded frame, and a telescopic fireproof cover. The top plate is connected to the upper right side of the upright via two fixed connecting rods. The embedded frame is connected to the lower part of the top plate via the telescopic fireproof cover. A rope-retracting motor is installed above the top plate, with two rope-retracting wheels connected to its front end. A frame is installed on each of the left and right sides of the top plate, with an inner rotating wheel installed between the two frames. Traction ropes are routed around the two inner rotating wheels and connected to the two rope-retracting wheels on the upper left and right sides of the embedded frame. The left traction rope is connected to the upper part of the rear rope-retracting wheel, and the right traction rope is connected to the lower part of the front rope-retracting wheel. A charging pile base plate is connected to the upper right side of the dry powder box. A docking groove is formed on the outer edge of the upper surface of the charging pile base plate. Four support legs are installed below the plate. A lower magnetic suction plate is installed in the docking groove. An upper magnetic suction plate is installed on the lower surface of the embedded frame. A dry powder pump is installed on the upper right side of the dry powder box. A powder inlet pipe is installed on the lower surface of the top plate. A top nozzle is installed at the right end of the powder inlet pipe. A rear camera is installed on the lower right side of the top crossbar. A front camera is installed on the lower left side of the upright. A temperature sensor and a flame sensor are installed below the upper camera and below the two front cameras, respectively. A flame sensor is installed below the rear camera. A flame sensor is installed on the lower surface of the top plate. A collision alarm mechanism with a prompting function is provided in the middle of the upright. An anti-occupancy mechanism to prevent parking space occupation is provided on the left side of the dry powder box. An identification control mechanism is provided on the left side of the rear upright.

[0011] Preferably, the lower surface of the upper magnetic absorbing sheet and the upper surface of the lower magnetic absorbing sheet are arranged with opposite magnetic poles, the telescopic fireproof cover is made of a fireproof and flame-retardant material, the powder inlet pipe is connected to a second dry powder pump through a transmission hose, and the second dry powder pump is connected to the inside of the dry powder box through an extraction pipe.

[0012] When a vehicle catches fire, the cloud system sends instructions and control signals to the central control module. The central control module simultaneously transmits electrical signals to the charging pile's electronic control module. The charging pile's electronic control module supplies power to the terminal charging pile and controls the start of the rope winding motor, causing it to reverse. After the rope winding motor reverses, it drives the two rope winding wheels to rotate, releasing the two traction ropes. As the traction ropes are released, the embedded frame descends, causing the telescopic fireproof cover to extend downwards. The release of the traction ropes also drives the two inner rotating wheels to rotate. After the embedded frame descends, it is embedded in the docking slot. At the same time, the lower magnetic plate and the upper magnetic plate attract each other with opposite poles, sealing the charging pile inside the telescopic fireproof cover and preventing the vehicle fire from affecting the charging pile.

[0013] Preferably, the anti-occupancy mechanism includes a parking space barrier frame, a license plate recognition camera, and a hollow pole. The parking space barrier frame is provided above the pre-embedded base frame. The license plate recognition camera is installed in the middle of the left side of the parking space barrier frame. The hollow pole is installed on the lower left side of the parking space barrier frame. A fixing rod is installed below the hollow pole. A hollow lifting rod is provided on the lower right side of the parking space barrier frame. A rotating screw is provided below the hollow lifting rod. A lifting motor is installed on the lower right side of the pre-embedded base frame.

[0014] Preferably, the hollow lifting rod has an internal thread on its inner wall, the rotating screw is rotatably connected to the hollow lifting rod through the thread, the upper end of the fixed rod extends into the hollow rod, and the output end of the lifting motor is connected to the lower end of the rotating screw.

[0015] Before a vehicle enters the parking space, the parking space barrier is higher than the top surface of the space to prevent other objects from occupying it. During the vehicle's entry, the license plate recognition camera identifies the license plate number and transmits the data to the gate's timing module. The system times the vehicle entry. After recognition is complete, the main control module sends a command signal to the lifting motor, causing it to reverse. The lifting motor then drives the rotating screw in reverse, which in turn lowers the parking space barrier via the hollow lifting rod. As the barrier descends, it lowers the hollow rod outside the fixed rod, bringing the barrier level with the parking space floor, making it easier for vehicles to enter.

[0016] Preferably, the impact alarm mechanism includes an impact plate, a protective pad, and a linkage rotating plate. The impact plate has a protective pad installed on its left side and a linkage rotating plate installed on its right side. A central rod is installed in the middle of the right side of the linkage rotating plate. The front and rear ends of the central rod are respectively connected to the upright. A limiting plate is provided on the upper right side of the linkage rotating plate, and an audible and visual alarm plate is provided on the upper left side of the audible and visual alarm plate. A push switch is installed on the right side of the audible and visual alarm plate.

[0017] Preferably, the push switch is connected to the sound and light alarm panel, and both ends of the sound and light alarm panel and both ends of the limiting plate are connected to the upright. The sound and light alarm panel is composed of a flashing alarm light and an alarm.

[0018] If the rear or front of the vehicle hits the impact plate during entry, the protective pad will first protect the vehicle from damage. After the impact, the impact plate will push the linkage plate to rotate outside the center rod. The upper end of the linkage plate will rotate towards the press switch to squeeze it. When the press switch is under pressure, it can turn on the external power supply to power the sound and light alarm board, which will then emit an alarm sound and light to promptly remind the driver to stop.

[0019] Preferably, the identification control mechanism includes a control box, an integrated circuit board, and a master control module. The integrated circuit board is installed inside the control box, the master control module is installed in the middle of the integrated circuit board, and an identification module is provided on the right side of the master control module. The identification control mechanism is connected to the cloud system and is also connected to the fire extinguishing drive mechanism, the fireproof enclosure mechanism, and the anti-occupancy mechanism.

[0020] Preferably, the multiple temperature sensors, multiple flame sensors, upper camera, license plate recognition camera, front camera, and rear camera are all electrically connected to the recognition module through a data acquisition module. The recognition module is electrically connected to the main control module. The main control module is electrically connected to motor one, drive motor, lifting motor, motor two, motor three, dry powder pump one, rope winding motor, charging pile control module, and dry powder pump two. The license plate recognition camera is connected to the parking lot gate timing module. The main control module is connected to the cloud system. All electrically driven components of this invention are connected to an independent power supply.

[0021] Preferably, a monitoring method for a charging pile monitoring device includes the following steps:

[0022] Step 1: During vehicle charging, the upper and front cameras monitor the area around the vehicle, the rear camera monitors the charging station, and the temperature sensor detects the temperature around the vehicle. When the temperature exceeds the threshold, the data acquisition module transmits the temperature data to the recognition module for identification. The collected data is analyzed in depth, and when an anomaly is detected, it is transmitted to the cloud system through the central control module to promptly alert the staff.

[0023] Step 2: While the vehicle is charging, the flame sensor detects the light or radiation of a specific wavelength produced by the flame to determine whether there is a flame and detect whether the vehicle and the charging station catch fire during the charging process.

[0024] Step 3: When a fire is detected, the data acquisition module transmits the data to the identification module for in-depth analysis and identification. After confirming the fire, the identification module transmits the electrical signal to the central control module. The cloud system sends instructions and control signals to the central control module. The central control module controls the fire extinguishing drive mechanism to drive the dry powder nozzle to aim at the fire point on the vehicle and spray fire extinguishing dry powder to accurately extinguish the fire.

[0025] Step 4: The main control module simultaneously cuts off the power to the charging pile through the charging pile control module and controls the activation of the fireproof enclosure mechanism to enclose the charging pile inside the telescopic fireproof cover, preventing the fire from the vehicle from affecting the charging pile.

[0026] Step 5: If the charging station catches fire, enclose the charging station inside the telescopic fireproof cover to prevent the flames from spreading to the outside. At the same time, spray fire extinguishing dry powder into the telescopic fireproof cover through the top nozzle to quickly extinguish the fire on the charging station. Seal the charging station inside the telescopic fireproof cover to prevent oxygen from entering and accelerate the extinguishing of the flames.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the present invention provides a charging pile monitoring device and monitoring method, which has the following beneficial effects:

[0029] 1. By setting up a fire extinguishing drive mechanism, when a fire occurs while the vehicle is charging, the position of the dry powder nozzle can be flexibly adjusted so that the dry powder is aimed at the fire point, thereby accurately extinguishing the fire point on the vehicle. Accurate aiming at the fire point means that the dry powder can act directly on the fire source, quickly extinguish the flames, shorten the fire extinguishing time, and the accurate fire extinguishing can reduce the impact on the non-fired parts of the vehicle, reducing the additional damage to the vehicle caused by fire extinguishing.

[0030] 2. By setting up a closed fireproof mechanism, the charging pile can be quickly sealed inside the telescopic fireproof cover when the vehicle catches fire, avoiding direct damage to the charging pile caused by the vehicle fire, reducing the cost of charging pile maintenance or replacement, and preventing the flames from spreading to the outside by sealing the charging pile inside the telescopic fireproof cover. At the same time, it can quickly extinguish the fire on the charging pile, and also prevent oxygen from entering by sealing the charging pile inside the telescopic fireproof cover, thus accelerating the extinguishing of the flames.

[0031] 3. By setting up an anti-occupancy mechanism, the parking space is blocked by raising the parking space frame before it is used, thereby preventing other objects from occupying the parking space and ensuring that the parking space owner can use it immediately when needed without spending time clearing or waiting for other objects to be moved.

[0032] 4. By setting up a collision warning mechanism, when a vehicle enters the parking space for charging, if too many vehicles enter, the driver can be promptly alerted. This effectively prevents vehicles from colliding with charging piles or surrounding facilities due to excessive entry into the parking space, thus preventing damage to the vehicle's appearance and structure.

[0048] Please see Figure 1-9 This invention provides a technical solution for a charging pile monitoring device and monitoring method:

[0049] Example 1: A charging pile monitoring device includes: a pre-embedded base frame 1, a dry powder box 3, and a pole 4. The dry powder box 3 is installed behind the pre-embedded base frame 1, and the pole 4 is installed above the dry powder box 3. A fire extinguishing drive mechanism 6 is provided above the pole 4. The fire extinguishing drive mechanism 6 includes a top horizontal bar 61, a side sliding groove 62, and a moving frame 63. A side sliding groove 62 is opened on the left and right sides of the top horizontal bar 61. A moving frame 63 is provided above the top horizontal bar 61. A drive motor 64 is installed on the right side inside the moving frame 63, and a motor 67 is installed on the left side of the moving frame 63. A front circular block is connected to the left side of the motor 67. 68. A second motor 69 is installed behind the front circular block 68. A drive rod 612 is located in front of the front circular block 68. A rotating frame 610 is located in front of the drive rod 612. A rotating rod 613 is installed in the middle of the rotating frame 610. A dry powder nozzle 614 is connected in the middle of the rotating rod 613. A third motor 611 is installed on the left side of the rotating frame 610. A drive wheel 617 is installed on the right side below the moving frame 63. A driven wheel 616 is installed on the left side below the drive wheel 617. A dry powder pump 615 is installed on the left side above the dry powder box 3. A base block 66 is installed above the moving frame 63. An upper camera 65 is installed above the base block 66.

[0050] The output end of motor 1 67 is connected to the front circular block 68, the output end of motor 2 69 is connected to the drive rod 612, the output end of motor 3 611 is connected to the rotating rod 613, the dry powder pump 1 615 is connected to the dry powder nozzle 614 through the transmission hose, and is connected to the inside of the dry powder box 3 through the extraction pipe. The dry powder box 3 is filled with fire extinguishing dry powder. The drive wheel 617 and the driven wheel 616 are both in contact with the inner wall of the side sliding groove 62, and the output end of the drive motor 64 is connected to the drive wheel 617.

[0051] In practical use, before actual use, the pre-embedded base frame 1 is buried under the charging parking space, and the dry powder box 3 is also buried underground with its upper end protruding above the ground. Simultaneously, the charging pile is installed above the charging pile base plate 79, with the lower surface of the support feet in contact with the ground. Then, the charging gun cable is passed under the charging pile base plate 79 to prevent obstruction of the telescopic fireproof cover 74. When the vehicle enters the parking space and charges through the charging pile, the front camera 716 and the upper camera 65 can capture vehicle images and upload them to the cloud for staff to view. Throughout the vehicle charging process, three temperature sensors 718 can detect the temperature at different locations around the vehicle. When the vehicle temperature detected by these three temperature sensors 718 is higher than a preset normal threshold, the data acquisition module transmits these temperature data to the recognition module. After receiving the data, the recognition module will... The system conducts a thorough and comprehensive analysis, carefully comparing the current temperature data with the normal range, and considering factors such as the rate and duration of temperature changes. If the analysis indicates an abnormal temperature, the identification module generates a high-temperature electrical signal, which is then transmitted to the cloud system via the central control module. Upon receiving the signal, the cloud system promptly issues a temperature alarm to relevant personnel. If the data identification results are normal, it means that the temperature around the vehicle is within a safe range and there is no abnormal increase. In this case, the data acquisition module continues to collect temperature data at the set frequency, and the identification module continuously monitors and analyzes the newly collected data to ensure that any potential abnormal temperature changes can be detected in a timely manner. The entire system will operate stably without triggering alarms.

[0052] Simultaneously, the three front flame sensors 719 can detect light or radiation of specific wavelengths produced by flames to determine the presence of flames and detect whether the vehicle and charging pile are on fire during charging. The data acquisition module detects whether the vehicle is on fire during charging and transmits the collected data to the identification module. The identification module performs in-depth identification. If the vehicle is on fire, the identification module transmits an electrical signal to the central control module, which sends a fire alarm signal to the cloud. At this time, the cloud system can send instructions and control signals to the central control module. Under the observation of the upper camera 65 and the front camera 716, the drive motor 64 is started. The drive motor 64 drives the drive wheel 617 to rotate along the path of the side slide groove 62, thereby moving the moving frame 63. The moving frame 63 drives the driven wheel 616 to move along the path of the side slide groove 62, so that the dry powder nozzle 614 moves to the vicinity of the vehicle fire position. When the moving frame 63 moves, it moves the upper camera 65 to the fire position. To facilitate accurate observation of the fire point, the system moves to the vicinity of the vehicle's fire. Once there, the main control module sends commands to motors 67, 69, and 611 to drive their operation. The forward and reverse rotation of motor 67 rotates the front circular block 68, causing the rotating frame 610 to rotate around motor 67. Motor 69 then drives the drive rod 612, which in turn rotates the rotating frame 610 around its axis. Motor 611 drives the rotating rod 613, which in turn rotates the dry powder nozzle 614 around its axis. This allows for flexible adjustment of the dry powder nozzle 614's position, ensuring it is aimed at the fire point. After aiming at the vehicle's fire point, the main control module sends a start signal to dry powder pump 615. Dry powder pump 615 draws fire extinguishing dry powder from the dry powder tank 3 through the extraction pipe and transmits it to the dry powder nozzle 614 through the transmission hose, thus precisely extinguishing the fire at the vehicle's fire point.

[0053] Example 2: A closed fireproof mechanism 7 is provided behind the upright 4. The closed fireproof mechanism 7 includes a fixed connecting rod 71, a top plate 72, an embedded frame 73, and a telescopic fireproof cover 74. The top plate 72 is connected to the upper right side of the upright 4 through two fixed connecting rods 71. The embedded frame 73 is connected to the lower part of the top plate 72 through the telescopic fireproof cover 74. A rope-taking motor 75 is installed on the top plate 72. Two rope-taking wheels 77 are connected to the front end of the rope-taking motor 75. A frame 76 is installed on the left and right sides of the top plate 72. An inner rotating wheel 78 is installed in the middle of the two frame 76. The upper left and right sides of the embedded frame 73 are connected to the two rope-taking wheels 77 by traction ropes passing around the two inner rotating wheels 78. The left traction rope is connected to the upper part of the rear rope-taking wheel 77, and the right traction rope is connected to the lower part of the front rope-taking wheel 77. A charging pile base plate 79 is connected to the upper right side of the dry powder box 3. A docking groove 710 is opened at the outer edge of the upper surface of the charging pile base plate 79. Four support legs are installed below. A lower magnetic suction plate 711 is installed in the docking groove 710. An upper magnetic suction plate 712 is installed on the lower surface of the embedded frame 73. A dry powder pump 615 is installed on the upper right side of the dry powder box 3. A powder inlet pipe 713 is installed on the lower surface of the top plate 72. A top nozzle 714 is installed at the right end of the powder inlet pipe 713. A rear camera 717 is installed on the lower right side of the top crossbar 61. A front camera 716 is installed on the lower left side of the upright 4. A temperature sensor 718 and a flame sensor 719 are installed below the upper camera 65 and below the two front cameras 716, respectively. A flame sensor 719 is installed below the rear camera 717. A flame sensor 719 is installed on the lower surface of the top plate 72. A collision alarm mechanism 8 with a prompting function is provided in the middle of the upright 4. An anti-occupancy mechanism 2 to prevent parking space occupation is provided on the left side of the dry powder box 3. An identification control mechanism 5 is provided on the left side of the rear upright 4.

[0054] The lower surface of the upper magnetic absorbing piece 712 and the upper surface of the lower magnetic absorbing piece 711 are set with opposite magnetic poles. The telescopic fireproof cover 74 is made of a fireproof and flame-retardant material. The powder inlet pipe 713 is connected to the dry powder pump 715 through the transmission hose. The dry powder pump 715 is connected to the inside of the dry powder box 3 through the extraction pipe.

[0055] In specific use, further explanation is given in conjunction with Embodiment 1. When the vehicle catches fire, the cloud system sends instructions and control signals to the central control module. Simultaneously, the central control module transmits electrical signals to the charging pile control module. The charging pile control module supplies power to the charging pile and simultaneously controls the rope winding motor 75 to start and reverse. The reverse rotation of the rope winding motor 75 drives the two rope winding wheels 77 to rotate, releasing the two traction ropes. Simultaneously, the embedded frame 73 descends, causing the telescopic fireproof cover 74 to extend downwards. The release of the traction ropes drives the two inner rotating wheels 78 to rotate. After the embedded frame 73 descends, it embeds itself into the docking groove 710. At the same time, the lower magnetic plate 711 and the upper magnetic plate 712 attract each other, sealing the charging pile inside the telescopic fireproof cover 74 to prevent the vehicle fire from affecting and damaging the charging pile. During charging pile use, the flame sensor 719 located above the top plate 72 and the rear camera 71... The flame sensor 719 below 7 can also detect light or radiation of a specific wavelength produced by a flame to determine whether a flame exists and detect whether the vehicle and charging pile catch fire during charging. At the same time, the rear camera 717 can capture images of the area around the charging pile for cloud-based management. If the charging pile catches fire, in conjunction with the above, the telescopic fireproof cover 74 will also descend to cut off the power to the charging pile, preventing the fire from spreading to the outside. At the same time, after the charging pile is sealed inside the telescopic fireproof cover 74, the oxygen concentration inside is greatly reduced by combustion, and the telescopic fireproof cover 74 can prevent external oxygen from entering, thereby accelerating the extinguishing of the flame. Simultaneously, the main control module sends a start signal to the dry powder pump 715. The dry powder pump 715 draws fire extinguishing dry powder through the extraction pipe and transmits it to the powder inlet pipe 713. Then, the fire extinguishing dry powder is sprayed around the charging pile through the top nozzle 714 to quickly extinguish the fire.

[0056] Example 3: The anti-occupancy mechanism 2 includes a parking space barrier frame 21, a license plate recognition camera 22, and a hollow rod 23. The parking space barrier frame 21 is provided above the pre-embedded base frame 1.

The hollow rod 23 is installed on the lower left side of the parking space barrier frame 21. A fixing rod 24 is installed below the hollow rod 23. A hollow lifting rod 25 is provided on the lower right side of the parking space barrier frame 21. A rotating screw 26 is provided below the hollow lifting rod 25. A lifting motor 27 is installed on the lower right side of the pre-embedded base frame 1.

[0057] The hollow lifting rod 25 has an internal thread on its inner wall. The rotating screw 26 is connected to the hollow lifting rod 25 by the thread. The upper end of the fixed rod 24 extends into the hollow rod 23. The output end of the lifting motor 27 is connected to the lower end of the rotating screw 26.

[0058] In practical use, before a vehicle enters the parking space, the parking space barrier 21 is higher than the upper surface of the parking space, thus preventing other objects from occupying it. During the vehicle's entry, the license plate recognition camera 22 can identify the license plate number and transmit the license plate data to the gate timing module to time the vehicle. After the identification is completed, the main control module sends a command signal to the lifting motor 27 to reverse it. The lifting motor 27 drives the rotating screw 26 to reverse, thereby driving the parking space barrier 21 to descend through the hollow lifting rod 25. When the parking space barrier 21 descends, it drives the hollow rod 23 to descend outside the fixed rod 24, so that the parking space barrier 21 descends to be level with the ground of the parking space, making it easier for the vehicle to enter. During this process, the upper camera 65 and the front camera 716 can identify the vehicle's outline. After the vehicle leaves, the main control module sends a forward control command to the lifting motor 27, thereby driving the lifting motor 27 to rotate the rotating screw 26 forward, which in turn drives the parking space barrier 21 to rise above the ground of the parking space through the hollow lifting rod 25, forming a barrier to prevent other objects from occupying it.

[0059] Example 4: The impact alarm mechanism 8 includes an impact plate 81, a protective pad 82, and a linkage rotating plate 83. The protective pad 82 is installed on the left side of the impact plate 81, and the linkage rotating plate 83 is installed on its right side. A center rod 84 is installed in the middle of the right side of the linkage rotating plate 83. The front and rear ends of the center rod 84 are connected to the upright rod 4 respectively. A limit plate 87 is provided on the upper right side of the linkage rotating plate 83, and an audible and visual alarm plate 85 is provided on the upper left side of the audible and visual alarm plate 85. A push switch 86 is installed on the right side of the audible and visual alarm plate 85.

[0060] The push switch 86 is connected to the sound and light alarm panel 85. The front and rear ends of the sound and light alarm panel 85 and the front and rear ends of the limit plate 87 are all connected to the upright 4. The sound and light alarm panel 85 is composed of a flashing alarm light and an alarm.

[0061] In practical use, as further explained in Embodiment 3, if the rear or front of the vehicle impacts the impact plate 81 during the vehicle's entry process, the protective pad 82 can first protect the vehicle and prevent damage. After the impact, the impact plate 81 pushes the linkage plate 83 to rotate outside the center rod 84. The upper end of the linkage plate 83 rotates towards the press switch 86 to press it. After the press switch 86 is under pressure, it can turn on the external power supply to power the audible and visual alarm plate 85, enabling it to start. At the same time, the audible and visual alarm plate 85 can emit an alarm sound and light to promptly remind the driver to stop. After the vehicle moves away, the linkage plate 83 and the impact plate 81 descend due to gravity. At the same time, the upper right side of the linkage plate 83 contacts the limiting plate 87 to limit it, thereby enabling the linkage plate 83 to return to its original position.

[0062] The identification control mechanism 5 is connected to the fire extinguishing drive mechanism 6, the fire-proof enclosure mechanism 7, and the anti-occupancy mechanism 2.

[0063] Multiple temperature sensors 718, multiple flame sensors 719, an upper camera 65, a license plate recognition camera 22, a front camera 716, and a rear camera 717 are all electrically connected to the recognition module through a data acquisition module. The recognition module is electrically connected to the main control module. The main control module is electrically connected to motor 1 67, drive motor 64, lifting motor 27, motor 2 69, motor 3 611, dry powder pump 1 615, rope winding motor 75, charging pile control module, and dry powder pump 2 715. The license plate recognition camera 22 is connected to the parking lot gate timing module. The main control module is connected to the cloud system. All electrically driven components of this invention are connected to an independent power supply.

[0064] A monitoring method for a charging pile monitoring device includes the following steps:

[0065] Step 1: During vehicle charging, the upper camera 65 and the front camera 716 monitor the area around the vehicle, the rear camera 717 monitors the charging station, and the temperature sensor 718 detects the temperature around the vehicle. When the temperature exceeds the threshold, the data acquisition module transmits the temperature data to the recognition module for identification. The collected data is analyzed in depth, and when an anomaly is detected, it is transmitted to the cloud system through the central control module to promptly alert the staff.

[0066] Step 2: While the vehicle is charging, the flame sensor 719 detects light or radiation of a specific wavelength produced by the flame to determine whether there is a flame and detect whether the vehicle and the charging station catch fire during the charging process.

[0067] Step 3: When a fire is detected, the data acquisition module transmits the data to the identification module for in-depth analysis and identification. After confirming the fire, the identification module transmits the electrical signal to the central control module. The cloud system sends instructions and control signals to the central control module. The central control module controls the fire extinguishing drive mechanism 6 to drive the dry powder nozzle 614 to aim at the fire point on the vehicle and spray fire extinguishing dry powder to accurately extinguish the fire.

[0068] Step 4: The main control module simultaneously cuts off the power to the charging pile through the charging pile control module and controls the activation of the fireproof enclosure 7, so that the charging pile is enclosed inside the telescopic fireproof cover 74 to prevent the fire from the vehicle from affecting the charging pile.

[0069] Step 5: If the charging station catches fire, the fire is contained within the telescopic fireproof cover 74 to prevent the flames from spreading to the outside. At the same time, fire extinguishing dry powder is sprayed into the telescopic fireproof cover 74 through the top nozzle 714 to quickly extinguish the fire on the charging station. The fire is also sealed inside the telescopic fireproof cover 74 to prevent oxygen from entering, thus accelerating the extinguishing of the flames.

[0070] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
