Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle parking systems, and in particular to an automatic fire extinguishing electric vehicle parking system. Background Art

[0002] While electric bicycles offer convenience for people, they also pose a number of safety risks, particularly fire. According to statistics, fires caused by electric bicycle charging and spontaneous combustion have occurred frequently in recent years, posing a serious threat to life and property. Currently, most communities are equipped with electric vehicle sheds and charging stations within them to facilitate charging, reducing the risk of fires in residential buildings.

[0003] However, existing carports still have many shortcomings in terms of fire prevention and firefighting. Common carport automatic fire extinguishing systems often use smoke detectors, smoke alarms, or security cameras, in conjunction with fire extinguishers such as fire extinguishers or fire hydrants, and power-off devices. However, these systems often suffer from problems such as delayed detection and inaccurate positioning. For example, traditional sprinkler fire extinguishers use point-based fire detection, which has a blind spot. If the burning vehicle is located between two detectors, the sprinkler system may not be activated in time, causing the fire to spread. Hanging dry powder fire extinguishers are not very effective in open outdoor spaces, and the short spraying time after activation makes it difficult to completely extinguish the fire.

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] like Figure 1 As shown, an embodiment of the present application provides an electric vehicle parking system with automatic fire extinguishing, comprising: a visual recognition system: comprising a plurality of multimodal cameras arranged on the top and around the carport, for acquiring real-time images of the interior of the carport; an automatic spraying device: comprising a water pump, a spray pipe, a fire extinguishing agent storage tank and a plurality of atomizing nozzles connected to the spray pipe and the fire extinguishing agent storage tank, and the plurality of atomizing nozzles are evenly distributed on the top of the carport; a central control module: respectively connected to the visual recognition system and the automatic spraying device, and having a built-in fire recognition neural network model; the visual recognition system sends the real-time image of the interior of the carport to the central control module, and the central control module determines whether there is a fire in the carport based on the real-time image of the interior of the carport, and controls the automatic spraying device to turn on when there is a fire in the carport.

[0022] Equipped with a visual recognition system and automatic sprinkler system, the camera can be connected to the central control module via a high-speed data transmission line (such as optical fiber or high-quality network cable), ensuring stable and real-time data transmission. Connected to the central control module, the multimodal fusion visual recognition system, combined with a fire identification neural network model, can quickly and accurately detect fires in a variety of complex environments and precisely locate the fire point. Compared to traditional detection methods, this greatly improves the timeliness and accuracy of fire detection, completely eliminating detection blind spots and buying valuable time for firefighting operations.

[0023] The central control module can include a built-in deep learning neural network model for fire identification. This model can be trained with a large amount of real-world fire image and video data, giving it powerful feature extraction and pattern recognition capabilities. During the daily operation of the carport, the neural network model can also continuously analyze the video streams captured by the cameras in real time, constantly learning and updating fire characteristic patterns.

[0024] At the same time, the image information captured by multiple cameras from different angles can be used, and the triangulation positioning principle and three-dimensional space modeling technology can be combined. The central control module can quickly and accurately calculate the three-dimensional coordinate position of the fire point in the carport.

[0025] In addition, the first step is to build an electric vehicle parking system. The carport should be constructed with steel structures or other materials that meet fire safety standards to ensure that the carport has sufficient strength and stability. The top of the carport should be covered with fireproof and waterproof panels, and open or semi-open enclosures can be set up around it according to actual needs. During the construction of the carport, holes and line channels for various types of equipment should be reserved, especially the position of the sliding rails for the sprinkler equipment on the top of the carport. Ensure that the structure is strong and can withstand the weight and impact of the equipment during operation. Rationally plan the electric vehicle parking spaces in the carport and set clear parking markings to ensure that the vehicles are parked neatly and orderly without affecting the normal operation of the fire extinguishing equipment and the evacuation of personnel. At the same time, the distribution of parking spaces should be reasonably adjusted according to the layout of the automatic sprinkler system.

[0026] The camera can be connected to the central control module through a high-speed data transmission line (such as optical fiber or high-quality network cable) to ensure the stability and real-time performance of data transmission.

[0027] As an optional embodiment, the multimodal camera includes a visible light camera for taking high-resolution images to capture real-time images inside the carport; the central control module analyzes the object features in the images taken by the visible light camera to identify the flame shape and / or smoke diffusion.

[0028] Visible light cameras can use high-resolution images to capture real-time images inside the carport. The central control module then uses image recognition algorithms to analyze features such as object contours, colors, and textures to identify signs of fire such as flame shape and smoke diffusion.

[0029] As an optional implementation, the multimodal camera further includes: an infrared thermal imaging camera for real-time monitoring of the temperature distribution in the carport.

[0030] Infrared thermal imaging cameras monitor the temperature distribution within the carport in real time, quickly locating areas of abnormally high temperatures. They can effectively detect fire hazards even in environments with limited visible light, such as dense smoke and darkness. Ultraviolet flame detection cameras specifically detect ultraviolet radiation generated by flames, offering extremely high sensitivity and accuracy in identifying early-stage flames.

[0031] As an optional implementation, the multimodal camera further includes: an ultraviolet flame detection camera for detecting ultraviolet radiation generated by flames.

[0032] The ultraviolet flame detection camera is specifically designed to detect the ultraviolet radiation generated by flames, and has extremely high sensitivity and accuracy in identifying early flames.

[0033] As an optional embodiment, the automatic spraying device includes multiple spraying units, each of which includes a control valve and one or more atomizing nozzles; when the central control module recognizes that a fire has occurred in the carport, the fire point and fire range are determined based on the real-time image inside the carport, and the control valves of different spraying units are controlled to open according to the fire point and the fire range.

[0034] The automatic sprinkler pipes installed on the carport roof can adopt a modular zoning design, dividing the carport into multiple independent fire-fighting zones, each equipped with its own control valve and atomizing nozzle. Once the central control module locates the fire source through a visual recognition system, it precisely controls the opening of the sprinkler pipe control valves corresponding to the fire zone and adjacent hazardous areas according to pre-set zoning rules. The nozzles can utilize new wide-angle atomizing nozzles, which can spray the fire extinguishing agent (such as a mixture of high-efficiency, environmentally friendly foam and water) in a uniform, fine mist, quickly forming a fire barrier around the fire source with wide coverage and effective extinguishing effect.

[0035] As an optional embodiment, a pressure sensor is provided in the atomizing nozzle and connected to the central control module for obtaining the water pressure in the atomizing nozzle and sending the water pressure information to the central control module. The central control module adjusts the working state of the water pump according to the water pressure information.

[0036] The sprinkler can be equipped with a built-in pressure sensor to monitor the water pressure in the pipeline in real time and feed the data back to the central control module. The central control module automatically adjusts the working status of the water pump according to the changes in water pressure to ensure that the fire extinguishing agent can be sprayed continuously and stably, effectively extinguishing the fire and preventing the fire from spreading.

[0037] As an optional embodiment, the automatic spraying device includes a slide rail installed parallel to the parking direction of the electric vehicle, and the atomizing nozzle is connected to the slide rail via a pulley set.

[0038] Two rails can be installed on the roof of the carport, parallel to the parking direction of the electric vehicle. These rails can be made of high-strength, high-temperature-resistant metal to withstand the weight and impact of the automatic spraying device during movement. The automatic spraying device is connected to the rails via a pulley system made of low-friction, highly wear-resistant material to ensure smooth sliding of the automatic spraying device on the rails. The main body of the automatic spraying device is a cylindrical tank that stores a highly efficient and environmentally friendly fire extinguishing agent. A micro water pump and an electronically controlled valve can be installed above the tank. The micro water pump is connected to the nozzle via a pipe, and the electronically controlled valve is used to control the delivery of the fire extinguishing agent.

[0039] As an optional implementation, the automatic spraying device further includes a visual sensor and a small processor connected to each other, and the visual sensor is connected to the central control module.

[0040] The small processor can have a built-in path planning algorithm. After receiving the coordinates of the fire point, it combines the real-time image of the vehicle parking layout in the carport to quickly plan the optimal movement path. At the same time, by controlling the motor drive of the pulley group, the sprinkler equipment moves along the slide rail toward the fire point. During the movement, the visual sensor continuously monitors the surrounding environment and uses the visual algorithm to adjust the movement direction in real time to avoid obstacles and ensure accurate arrival above the fire point. After reaching the fire point, the central control module sends a command to open the electronically controlled valve, and the micro-water pump sprays the fire extinguishing agent through the nozzle in the form of high-pressure mist, providing close-range, high-intensity fire extinguishing at the fire point. The nozzle can rotate 360 ​​degrees and adjust the pitch up and down, which can fully cover the fire area and ensure the fire extinguishing effect.

[0041] As an optional implementation, the visual sensor is used to receive the ignition point coordinate information sent by the central control module in real time, and send the ignition point coordinate information to the small processor, and the small processor plans the path of the atomizing nozzle according to the ignition point coordinate information.

[0042] As an optional embodiment, a liquid level sensor is also provided in the fire extinguishing agent storage tank, which is connected to the central control module and is used to obtain the remaining amount of fire extinguishing agent in the fire extinguishing agent storage tank and send the remaining amount information of the fire extinguishing agent to the central control module. The central control module determines the size relationship between the remaining amount information of the fire extinguishing agent and the preset remaining amount threshold, and outputs an output signal for reminding the user to replenish the fire extinguishing agent when the remaining amount of the fire extinguishing agent is less than or equal to the preset remaining amount threshold.
