Description

Technical Field

[0001] This application relates to the field of fire extinguishing technology for charging sheds, and more specifically, to an automatic fire extinguishing system and method for electric bicycle charging sheds. Background Technology

[0002] With the increasing popularity of electric bicycles in cities, electric bicycle charging sheds are also becoming more and more common as an important supporting facility. To ensure the fire safety of electric bicycle charging sheds, most of them are now equipped with fire detectors. These fire detectors typically include smoke detectors, temperature detectors, or simple spectral detectors, used to monitor the fire risk inside the electric bicycle charging shed in real time.

[0003] However, existing technologies, when detecting a fire in an electric bicycle charging shed, typically require sending fire information to the relevant personnel's terminal devices (such as mobile phones or tablets). These personnel then need to remotely control the shed's fire suppression system via their devices. This reliance on manual intervention has significant limitations. Since personnel do not always carry or constantly check their devices, they may not be able to receive and process fire information in a timely manner. If fire information is not processed promptly, the fire cannot be effectively contained, increasing the risk of injury and property damage. Therefore, existing technologies are insufficient in terms of fire response speed and automation, necessitating a solution that enables rapid and automated fire suppression to effectively address the fire risks associated with electric bicycle charging sheds.

[0004] There is currently no effective technical solution to the above problems. Summary of the Invention

[0005] The purpose of this application is to provide an automatic fire extinguishing system and method for electric bicycle charging sheds, which can effectively reduce the risk of personal injury and property damage.

[0006] In a first aspect, this application provides an automatic fire extinguishing system for electric bicycle charging sheds, comprising: Multiple fire detection sensors, used to collect different types of fire-related parameters, are installed on the electric bicycle charging shed. Each type of fire-related parameter corresponds to at least one fire detection sensor. The fire extinguishing actuator is located in the electric bicycle charging shed and is used to perform fire extinguishing actions; The controller is used to analyze whether a fire has occurred in the electric bicycle charging shed based on all fire-related parameters and their corresponding preset fire judgment thresholds. It is also used to generate and send alarm information based on the preset location information of the electric bicycle charging shed when a fire is detected, and to control the fire extinguishing actuator to perform fire extinguishing actions.

[0007] This application provides an automatic fire extinguishing system for electric bicycle charging sheds. By automatically identifying fire-related parameters of multi-source fires and directly controlling the fire extinguishing actuator to perform fire extinguishing actions when a fire is detected, the system eliminates the reliance on manual intervention. Therefore, this application can achieve a high degree of automation and real-time response in fire identification and extinguishing. This automated fire extinguishing mechanism can greatly shorten the time interval from the occurrence of a fire to the execution of the fire extinguishing action, effectively curbing the initial spread of the fire. Thus, this application can effectively reduce the risk of personal injury and property loss, thereby effectively improving the fire safety level of electric bicycle charging sheds.

[0008] Optionally, the process of analyzing whether a fire has occurred in the electric bicycle charging shed based on all fire-related parameters and their corresponding preset fire judgment thresholds includes: A1. When the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is 0 or 1, it is considered that no fire has occurred in the electric bicycle charging shed. A2. When the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is greater than or equal to 2, it is considered that a fire has occurred in the electric bicycle charging shed.

[0009] The controller of this technical solution adopts a judgment standard that "a fire is considered to have occurred only when the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is greater than or equal to 2". In other words, when the controller receives different types of fire-related parameters collected from multiple fire detection sensors, it will not determine a fire based on the abnormality of a single parameter. Therefore, this technical solution can effectively filter out false alarms caused by single sensor failure, local environmental disturbances, or non-fire events, thereby effectively avoiding unnecessary fire-fighting actions and thus effectively reducing the operating costs and maintenance burden of electric bicycle charging sheds.

[0010] Optionally, the fire extinguishing actuator includes a power switch mechanism and a fire extinguishing agent spraying assembly. The power switch mechanism is used to control the on / off of the power supply to the charging piles in the electric bicycle charging shed, and the fire extinguishing agent spraying assembly is used to store and spray the fire extinguishing agent. The process of controlling the fire extinguishing actuator to perform fire extinguishing actions includes: The control power switch mechanism cuts off the power supply to the charging piles of the electric bicycle charging shed, and controls the fire extinguishing agent spraying assembly to spray fire extinguishing agent onto the electric bicycle charging shed.

[0011] Optionally, the extinguishing agent is a water-based extinguishing agent. The extinguishing agent spraying assembly includes a water-based extinguishing agent storage tank. The automatic fire extinguishing system for electric bicycle charging sheds also includes an extinguishing agent replenishment assembly and a liquid level measurement assembly. The extinguishing agent replenishment assembly is connected to the water-based extinguishing agent storage tank via a delivery pipeline. The liquid level measurement assembly is installed on the water-based extinguishing agent storage tank and is used to collect extinguishing agent liquid level information in the water-based extinguishing agent storage tank. The controller is also used to control the extinguishing agent replenishment assembly to supply extinguishing agent to the water-based extinguishing agent storage tank when the extinguishing agent liquid level information is less than or equal to a first preset liquid level height, until the extinguishing agent liquid level information reaches a second preset liquid level height, where the first preset liquid level height is less than the second preset liquid level height.

[0012] Optionally, the controller is also used to control the extinguishing agent replenishment component to supply extinguishing agent to the water-type extinguishing agent storage tank when the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is 1 and the extinguishing agent level information is less than or equal to the third preset level height, until the extinguishing agent level information reaches the fourth preset level height, the third preset level height is greater than the first preset level height, and the fourth preset level height is greater than the third preset level height and greater than or equal to the second preset level height.

[0013] This technical solution can preventively replenish the extinguishing agent in the water-based extinguishing agent storage tank when there is a risk of fire, avoiding delays in extinguishing the fire due to insufficient extinguishing agent, and thus avoiding a decline in extinguishing efficiency and effectiveness. Therefore, this technical solution can effectively improve the response capability and reliability of the automatic fire extinguishing system in response to fire, thereby effectively improving the fire safety of electric bicycle charging sheds.

[0014] Optionally, the automatic fire extinguishing system for electric bicycle charging sheds also includes a fire extinguishing agent heating component and a temperature sensor. The fire extinguishing agent heating component is installed on the water-based fire extinguishing agent storage tank and is used to heat the fire extinguishing agent stored in the water-based fire extinguishing agent storage tank. The temperature sensor is installed on the water-based fire extinguishing agent storage tank and is used to collect the temperature information of the fire extinguishing agent stored in the water-based fire extinguishing agent storage tank. The controller is also used to control the fire extinguishing agent heating component to heat the fire extinguishing agent stored in the water-based fire extinguishing agent storage tank when the temperature information is less than or equal to a first preset temperature, until the temperature information reaches a second preset temperature. The first preset temperature is greater than the solidification temperature of the fire extinguishing agent, and the second preset temperature is greater than the first preset temperature.

[0015] Optionally, the process of analyzing whether a fire occurred in the electric bicycle charging shed is analyzed based on all fire-related parameters and their corresponding preset fire judgment thresholds: B1. Obtain the current environmental and operational status information of the electric bicycle charging shed; B2. Select one fire judgment logic group from multiple preset fire judgment logic groups based on environmental status information and operational status information. The fire judgment logic group includes preset fire judgment thresholds corresponding to different types of fire-related parameters. B3. Analyze whether a fire has occurred in the electric bicycle charging shed based on all fire-related parameters and their corresponding preset fire judgment thresholds.

[0016] This technical solution effectively improves the accuracy and reliability of fire detection by dynamically adjusting the fire detection threshold based on the real-time environmental and operational status information of the electric bicycle charging shed. Therefore, this technical solution can effectively reduce the occurrence of false alarms, thereby further enhancing the fire safety guarantee capability of the electric bicycle charging shed.

[0017] Optionally, there may be multiple fire detection sensors that collect the same type of fire-related parameters, and these multiple fire detection sensors that collect the same type of fire-related parameters may be evenly distributed on the electric bicycle charging shed.

[0018] Optionally, fire detection sensors include cable temperature sensors, infrared and ultraviolet flame detectors, visual sensors, photoelectric smoke detectors, and heat detectors.

[0019] Secondly, this application also provides an automatic fire extinguishing method for an electric bicycle charging shed, which is applied to the automatic fire extinguishing system for an electric bicycle charging shed provided in the first aspect above. The method includes the following steps: S1. Analyze whether a fire has occurred in the electric bicycle charging shed based on all fire-related parameters and their corresponding preset fire judgment thresholds. S2. When a fire is detected in the electric bicycle charging shed, an alarm message is generated and sent based on the preset location information of the electric bicycle charging shed, and the fire extinguishing actuator is controlled to perform fire extinguishing actions.

[0020] This application provides an automatic fire extinguishing method for electric bicycle charging sheds. By automatically identifying fire-related parameters of multi-source fires and directly controlling the fire extinguishing actuator to perform fire extinguishing actions when a fire is detected, this method eliminates the reliance on manual intervention in the fire extinguishing system. Therefore, this application can achieve a high degree of automation and real-time response in fire identification and extinguishing. This automated fire extinguishing mechanism can greatly shorten the time interval from the occurrence of a fire to the execution of the fire extinguishing action, effectively curbing the initial spread of the fire. Thus, this application can effectively reduce the risk of personal injury and property loss, thereby effectively improving the fire safety level of electric bicycle charging sheds.

[0021] As can be seen from the above, the automatic fire extinguishing system and method for electric bicycle charging sheds provided in this application eliminates the reliance on manual intervention in the fire extinguishing system by automatically identifying fire-related parameters of multi-source fires and directly controlling the fire extinguishing actuator to perform fire extinguishing actions when a fire is detected. Therefore, this application can achieve a high degree of automation and real-time response in fire identification and fire extinguishing. This automated fire extinguishing mechanism can greatly shorten the time interval from the occurrence of a fire to the execution of the fire extinguishing action, so as to effectively curb the initial spread of the fire. Therefore, this application can effectively reduce the risk of personal injury and property loss, thereby effectively improving the fire safety level of electric bicycle charging sheds.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Firstly, such as Figure 1 As shown, this application provides an automatic fire extinguishing system for electric bicycle charging sheds, comprising: Multiple fire detection sensors 1, used to collect different types of fire-related parameters, are installed on the electric bicycle charging shed. Each type of fire-related parameter corresponds to at least one fire detection sensor 1. Fire extinguishing actuator 2 is installed in the electric bicycle charging shed and is used to perform fire extinguishing actions; The controller 3 is used to analyze whether a fire has occurred in the electric bicycle charging shed based on all fire-related parameters and their corresponding preset fire judgment thresholds. It is also used to generate and send alarm information based on the preset location information of the electric bicycle charging shed when a fire is detected, and to control the fire extinguishing actuator 2 to perform fire extinguishing actions.

[0028] This application improves the accuracy of fire detection by setting up different types of fire detection sensors 1 to collect different types of fire-related parameters. Simultaneously, this application automates the fire response by automatically analyzing all fire-related parameters to determine if a fire has occurred in the electric bicycle charging shed, and promptly controlling the fire extinguishing actuator 2 to perform fire extinguishing actions when a fire occurs. Therefore, this application effectively avoids delays that may be caused by manual intervention, thereby significantly improving the fire safety level of the electric bicycle charging shed.

[0029] To better understand the technical solution of this application, the key terms and implementation environment involved will be described in detail below. The electric bicycle charging shed in this embodiment refers to a specific area or structure that provides charging services for electric bicycles. It typically contains multiple charging piles, all of which can be used to charge electric bicycles. The electric bicycle charging shed can be an open or semi-enclosed structure. A fire may occur if the electric bicycle battery is overcharged or if the wiring in the charging shed is short-circuited. The fire detection sensor 1 in this embodiment refers to a device capable of sensing and collecting physical or chemical parameters related to the occurrence of a fire. These parameters can be temperature, smoke concentration, flame radiation, gas composition, etc. Since the types of fire-related parameters collected by each fire detection sensor 1 are different, this embodiment is equivalent to using different types of fire detection sensors 1 to monitor fire risks from different dimensions. For example, the temperature sensor 7 can detect abnormal increases in ambient temperature, the smoke sensor can detect smoke particle concentration, and the flame detector can detect infrared or ultraviolet radiation of the flame. The fire extinguishing actuator 2 in this embodiment refers to a device capable of performing specific fire extinguishing actions. The fire extinguishing actuator 2 can be an existing fire protection system or an inert gas release system. In this embodiment, the controller 3 is preferably an existing PCBA motherboard, which is protected against lightning strikes. The controller 3 is responsible for receiving and processing fire-related parameters from the fire detection sensor 1 to make a fire judgment, and after confirming that a fire has occurred, generating alarm information and controlling the fire extinguishing actuator 2 to extinguish the fire.

[0030] The core of the automatic fire suppression system for electric bicycle charging sheds provided in this application lies in achieving rapid fire detection and automatic fire suppression through intelligent means. Firstly, the system is equipped with different types of fire detection sensors 1. These sensors are preferably installed at various key locations within the electric bicycle charging shed (e.g., near charging stations, on the roof, or in areas where flammable materials are stored). Each fire detection sensor 1 is used to collect different types of fire-related parameters. For example, a temperature sensor 7 is installed to monitor ambient temperature, a smoke sensor is installed to monitor smoke concentration in the air, and a flame detector is installed to monitor infrared or ultraviolet radiation from flames. This application enables comprehensive monitoring of fire risks from multiple dimensions through the collaborative work of these different types of sensors, avoiding delayed, false, or missed reports caused by using a single sensor for data collection (e.g., if the flame is obscured, a flame detector alone cannot detect the fire in time). Secondly, the system also includes a fire extinguishing actuator 2, which is also located inside the electric bicycle charging shed and connected to the controller 3. This actuator 2 can perform fire extinguishing actions according to the instructions of the controller 3. For example, the actuator 2 can be an automatic sprinkler system. When the controller 3 detects a fire in the electric bicycle charging shed, it generates and sends a fire extinguishing command to trigger the automatic sprinkler system to start its water pump and spray water mist onto the fire area through the nozzles. Finally, in this embodiment, the controller 3 continuously receives fire-related parameters collected from all fire detection sensors 1. The controller 3 internally presets fire judgment thresholds for each type of fire-related parameter. For example, for the temperature sensor 7, a temperature upper limit threshold is preset; for the smoke sensor, a smoke concentration upper limit threshold is preset. The controller 3 comprehensively analyzes whether a fire has occurred in the electric bicycle charging shed based on all received fire-related parameters and their corresponding preset fire judgment thresholds. For example, if any fire-related parameter reaches its corresponding preset fire judgment threshold, the controller considers the electric bicycle charging shed to be on fire. When analyzing and determining that a fire has occurred in an electric bicycle charging shed, the controller 3 will generate an alarm message based on the preset location information of the electric bicycle charging shed and send the alarm message to a preset recipient (such as the fire department, the terminal equipment of management personnel, etc.). At the same time, the controller 3 will quickly send a control command to the fire extinguishing actuator 2 to control the fire extinguishing actuator 2 to perform fire extinguishing actions, thereby realizing fire extinguishing at the first time a fire is discovered, effectively suppressing the spread of fire, and thus effectively reducing the risk of casualties and property losses.

[0031] Therefore, the automatic fire extinguishing system for electric bicycle charging sheds provided in this application can achieve rapid response and automatic handling of fires. Specifically, when a fire occurs in the electric bicycle charging shed, the fire detection sensor 1 immediately senses the physical or chemical changes related to the fire. For example, the temperature sensor 7 detects a sharp increase in ambient temperature, the smoke sensor detects an increase in smoke concentration, and the flame detector detects the radiation signal of the flame. Because multiple different types of fire detection sensors 1 are used, even if a single sensor malfunctions or the initial fire signal is not obvious, other sensors can still provide effective fire information, thereby improving the accuracy and reliability of fire detection. All fire-related parameters collected by the fire detection sensors 1 are transmitted to the controller 3 in real time. After receiving these parameters, the controller 3 compares and analyzes them with preset fire judgment thresholds. For example, the controller 3 determines whether the current temperature exceeds a preset temperature threshold, whether the smoke concentration exceeds a preset smoke concentration threshold, and whether there is a flame signal. Through comprehensive analysis of these multi-source heterogeneous data, the controller 3 can more accurately determine whether a fire has actually occurred in the electric bicycle charging shed, effectively avoiding false alarms and missed alarms. Once controller 3 analyzes and determines that a fire has occurred in the electric bicycle charging shed, it will immediately activate the emergency response mechanism: controller 3 will generate alarm information containing key information such as the fire location and time based on the preset location information of the electric bicycle charging shed. This alarm information will then be sent to the preset recipients so that relevant personnel can be informed of the fire situation in a timely manner and take further measures. At the same time, controller 3 controls the fire extinguishing actuator 2 to immediately perform fire extinguishing actions (such as spraying fire extinguishing agent and cutting off the power to the charging pile). Since the entire fire extinguishing process of this application does not require manual intervention, this application achieves full automation from fire detection to fire extinguishing execution, thereby greatly shortening the fire response time, effectively suppressing the spread of the fire, and thus minimizing the losses caused by the fire.

[0032] This application provides an automatic fire extinguishing system for electric bicycle charging sheds. By automatically identifying fire-related parameters of multi-source fires and directly controlling the fire extinguishing actuator 2 to perform fire extinguishing actions when a fire is detected, the fire extinguishing system eliminates the reliance on manual intervention. Therefore, this application can achieve a high degree of automation and real-time response in fire identification and fire extinguishing. This automated fire extinguishing mechanism can greatly shorten the time interval from the occurrence of a fire to the execution of the fire extinguishing action, effectively curbing the initial spread of the fire. Thus, this application can effectively reduce the risk of personal injury and property loss, thereby effectively improving the fire safety level of electric bicycle charging sheds.

[0033] In some preferred embodiments, the process of analyzing whether a fire has occurred in the electric bicycle charging shed based on all fire-related parameters and their corresponding preset fire judgment thresholds includes: A1. When the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is 0 or 1, it is considered that no fire has occurred in the electric bicycle charging shed. A2. When the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is greater than or equal to 2, it is considered that a fire has occurred in the electric bicycle charging shed.

[0034] In this embodiment, after receiving fire-related parameters collected from multiple fire detection sensors 1, the controller 3 compares these parameters one by one to see if they reach their respective preset fire judgment thresholds. If the total number of fire-related parameters that reach the preset fire judgment threshold is 0 or only 1, it is considered that no fire has occurred in the electric bicycle charging shed. If the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is greater than or equal to 2, it is considered that a fire has occurred in the electric bicycle charging shed. This means that in this embodiment, at least two different types of fire-related parameters need to reach or exceed their preset judgment thresholds at the same time to finally confirm the occurrence of a fire. For example, the system will only determine a fire when the temperature sensor 7 detects high temperature and the smoke sensor detects high concentration of smoke.

[0035] This embodiment effectively solves the problems of false alarms and missed alarms that may be caused by traditional single-parameter or simple logic judgment by introducing multi-parameter collaborative judgment logic. Specifically, the controller 3 of this embodiment adopts the judgment standard that "a fire is considered to have occurred only when the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is greater than or equal to 2". That is, when the controller 3 of this embodiment receives different types of fire-related parameters collected from multiple fire detection sensors 1, it will not determine a fire based on the abnormality of a single parameter. Therefore, this embodiment can effectively filter out false alarms caused by single sensor failure, local environmental disturbances, or non-fire events, thereby effectively avoiding unnecessary fire-fighting actions and thus effectively reducing the operating costs and maintenance burden of electric bicycle charging sheds.

[0036] In some preferred embodiments, it is assumed that the electric bicycle charging shed is equipped with multiple fire detection sensors 1, including a temperature sensor 7, a smoke sensor, and a flame sensor. Scenario 1: If only the temperature sensor 7 detects a temperature exceeding its corresponding preset fire judgment threshold, while the smoke sensor and flame sensor do not reach their respective preset fire judgment thresholds, then the total number of fire-related parameters reaching the preset fire judgment threshold is 1. The controller 3 will determine that no fire has occurred in the electric bicycle charging shed, thus avoiding false alarms caused by localized high temperatures (such as direct sunlight or temporary heat sources). Scenario 2: If the temperature sensor 7 detects a temperature exceeding its corresponding preset fire judgment threshold, and the smoke concentration detected by the smoke sensor also exceeds its corresponding preset fire judgment threshold, while the flame sensor does not reach its corresponding preset fire judgment threshold, then the total number of fire-related parameters reaching the preset fire judgment threshold is 2. The controller 3 will determine that a fire has occurred in the electric bicycle charging shed and immediately activate the fire extinguishing actuator 2, issuing an alarm message.

[0037] In some preferred embodiments, the fire extinguishing actuator 2 includes a power switch mechanism and a fire extinguishing agent spraying assembly. The power switch mechanism is used to control the on / off of the power supply to the charging piles of the electric bicycle charging shed, and the fire extinguishing agent spraying assembly is used to store and spray fire extinguishing agent. The process of controlling the fire extinguishing actuator 2 to perform fire extinguishing actions includes: The control power switch mechanism cuts off the power supply to the charging piles of the electric bicycle charging shed, and controls the fire extinguishing agent spraying assembly to spray fire extinguishing agent onto the electric bicycle charging shed.

[0038] The power switch mechanism of this embodiment can be understood as a device capable of remotely or automatically controlling the power supply status of the charging pile. This power switch mechanism can quickly cut off the power supply to the charging pile in the event of a fire to prevent the fire from spreading further due to electrical short circuits or overloads. Specifically, the power switch mechanism can be an existing intelligent circuit breaker, contactor, or relay group. The fire extinguishing agent spraying assembly of this embodiment refers to a device for storing fire extinguishing agents and spraying them onto the fire area. This fire extinguishing agent spraying assembly can extinguish flames through physical or chemical action. Specifically, the fire extinguishing agent spraying assembly can include one or more fire extinguishing agent storage tanks, delivery pipelines, nozzles, and a power device for driving the spraying. The type of fire extinguishing agent can be selected according to the fire characteristics of the electric bicycle charging shed, such as dry powder, water-based, gaseous, or foam fire extinguishing agents, to ensure the fire extinguishing effect. Preferably, in this embodiment, the power switch mechanism is first controlled to cut off the power supply to the charging pile of the electric bicycle charging shed, and then the fire extinguishing agent spraying assembly is controlled to spray fire extinguishing agent onto the electric bicycle charging shed.

[0039] This embodiment achieves comprehensive fire response by introducing a power switch mechanism and a fire extinguishing agent spraying assembly. When a fire occurs in an electric bicycle charging shed, this embodiment first controls the power switch mechanism to cut off the power to the charging pile, thereby quickly isolating the electrical hazards in the fire area, effectively preventing the spread of fire caused by electrical faults, and creating a safe environment for fire extinguishing operations. Subsequently, this embodiment controls the fire extinguishing agent spraying assembly to spray fire extinguishing agent onto the fire area to extinguish the flames. Since the electrical hazards in the fire area are completely eliminated during the fire extinguishing operation, this embodiment can effectively improve the safety and effectiveness of the fire extinguishing process and effectively avoid secondary accidents caused by live operation, thereby further reducing the risk of property damage and personal injury.

[0040] In some preferred embodiments, the extinguishing agent is a water-based extinguishing agent, and the extinguishing agent spraying assembly includes a water-based extinguishing agent storage tank. The automatic fire extinguishing system for electric bicycle charging sheds also includes an extinguishing agent replenishment assembly 4 and a liquid level measuring assembly 5. The extinguishing agent replenishment assembly 4 is connected to the water-based extinguishing agent storage tank through a delivery pipeline. The liquid level measuring assembly 5 is installed on the water-based extinguishing agent storage tank and is used to collect the extinguishing agent liquid level information in the water-based extinguishing agent storage tank. The controller 3 is also used to control the extinguishing agent replenishment assembly 4 to supply extinguishing agent to the water-based extinguishing agent storage tank when the extinguishing agent liquid level information is less than or equal to a first preset liquid level height, until the extinguishing agent liquid level information reaches a second preset liquid level height, where the first preset liquid level height is less than the second preset liquid level height.

[0041] The fire extinguishing agent spraying assembly of this embodiment consists of a water-based fire extinguishing agent storage tank and an existing spraying assembly. The fire extinguishing agent replenishment assembly 4 of this embodiment can be understood as a device for supplying fire extinguishing agent to the water-based fire extinguishing agent storage tank to ensure that there is always sufficient fire extinguishing agent in the water-based fire extinguishing agent storage tank. The fire extinguishing agent replenishment assembly 4 may include one or more storage tanks and one or more pumps. The fire extinguishing agent replenishment assembly 4 uses pumps to transport the fire extinguishing agent from the storage tank to the water-based fire extinguishing agent storage tank. The delivery pipeline of this embodiment can be an existing fire extinguishing agent delivery pipeline, which connects the fire extinguishing agent replenishment assembly 4 and the water-based fire extinguishing agent storage tank to provide a channel for the transmission of fire extinguishing agent. The liquid level measurement assembly 5 of this embodiment refers to a device for real-time monitoring of the fire extinguishing agent liquid level in the water-based fire extinguishing agent storage tank to obtain accurate fire extinguishing agent liquid level information. The liquid level measurement assembly 5 can be an existing float-type liquid level sensor, ultrasonic liquid level sensor, or pressure-type liquid level sensor, etc. These sensors can convert liquid level information into electrical signals and send them to the controller 3. In this embodiment, after receiving the extinguishing agent level information collected by the level measuring component 5, the controller 3 compares it with a preset first preset level height, which is equivalent to a warning value. If the extinguishing agent level information is less than or equal to the first preset level height, it indicates that the extinguishing agent in the water-based extinguishing agent storage tank has reached the critical point where it needs to be replenished. Therefore, when the extinguishing agent level information is less than or equal to the first preset level height, the controller 3 controls the extinguishing agent replenishment component 4 to supply extinguishing agent to the water-based extinguishing agent storage tank until the extinguishing agent level information reaches a second preset level height, which is equivalent to a target value. If the extinguishing agent level information reaches (is greater than or equal to) the second preset level height, it indicates that the extinguishing agent in the water-based extinguishing agent storage tank has been replenished to a safe or sufficient level. Since the first preset liquid level height in this embodiment is less than the second preset liquid level height, this embodiment is equivalent to initiating extinguishing agent replenishment when the extinguishing agent level in the water-based extinguishing agent storage tank drops to a certain level, so as to replenish the extinguishing agent in the water-based extinguishing agent storage tank to a safe level. It should be understood that, since the extinguishing agent in this embodiment is a water-based extinguishing agent, which requires premixing or use within a specific temperature range, this embodiment does not directly use the extinguishing agent in the extinguishing agent replenishment component, but uses the extinguishing agent in the water-based extinguishing agent storage tank. The direct use of the extinguishing agent in the extinguishing agent replenishment component is also based on the following key system design and functional considerations: the extinguishing agent spraying component and the extinguishing agent replenishment component have different functional positioning and design goals in the system. Specifically, the core function of the extinguishing agent spraying component is to achieve rapid and effective spraying of the extinguishing agent to respond to sudden fire situations. To achieve this goal, the water-based extinguishing agent storage tank of the extinguishing agent spraying component is designed to keep the extinguishing agent readily available. For example, the extinguishing agent may have been pre-pressurized, in an appropriate mixing ratio, and directly connected to the spraying pipeline and nozzle.When a fire occurs, the system can quickly activate the extinguishing agent spraying assembly, enabling the extinguishing agent to reach the fire source area in the shortest possible time, thereby controlling and extinguishing the fire to the greatest extent. Therefore, the extinguishing agent spraying assembly is the most direct and critical execution part of the entire fire suppression system, and its design optimization focuses on response speed and spraying efficiency. The main function of the extinguishing agent replenishment assembly is to provide the fire suppression system with the storage and replenishment capacity of the extinguishing agent. This means that it is usually a container that stores a large amount of extinguishing agent. Its design focuses on safe storage, convenient replenishment, and the transfer of extinguishing agent to other parts when needed (e.g., to water-based extinguishing agent tanks for refilling). If the extinguishing agent in the replenishment assembly is not in the pressurized state required for immediate spraying, or if its transmission path and flow design are not suitable for direct, rapid, and high-flow-rate spraying, directly taking extinguishing agent from the replenishment assembly for spraying may require additional pressurization devices, complex valve switching, and pipeline routing. This will significantly increase the system's response time, complexity, and potential points of failure, thereby affecting the timeliness and effectiveness of fire suppression. In summary, this application selects to use the extinguishing agent from the water-based extinguishing agent storage tank based on a comprehensive consideration of the fire extinguishing system's response speed, efficiency, and reliability. Specifically, the extinguishing agent spraying assembly is optimized for immediate fire suppression, ensuring the extinguishing agent is delivered and sprayed in the fastest and most effective manner when a fire occurs. The extinguishing agent replenishment assembly serves as a backup and maintenance component, ensuring a continuous supply of extinguishing agent. Both components perform their respective functions, together forming a complete and efficient fire extinguishing system. This design division ensures that the system can utilize components specifically designed for rapid response to extinguish the fire at the very first moment of its occurrence, thereby maximizing the fire suppression effect.

[0042] This embodiment introduces a fire extinguishing agent replenishment component 4 and a liquid level measurement component 5, which are intelligently controlled by a controller 3, to achieve real-time monitoring and automatic replenishment of the fire extinguishing agent level in the water-based fire extinguishing agent storage tank. Specifically, the liquid level measurement component 5 continuously collects the fire extinguishing agent level information in the water-based fire extinguishing agent storage tank and transmits this information to the controller 3. When the extinguishing agent level information received by controller 3 is lower than the first preset level, it indicates that the extinguishing agent supply is insufficient to cope with potential fire risks. At this time, controller 3 immediately controls the extinguishing agent replenishment component 4 to supply extinguishing agent to the water-based extinguishing agent storage tank through the delivery pipeline until the extinguishing agent level information fed back by the level measurement component 5 reaches the second preset level, so as to replenish the extinguishing agent in the water-based extinguishing agent storage tank to a sufficient state. Therefore, this embodiment can effectively avoid the situation where the fire extinguishing operation of the electric bicycle charging shed cannot continue due to insufficient extinguishing agent in the water-based extinguishing agent storage tank, and the fire spreads rapidly. This effectively improves the continuous fire extinguishing capability of the automatic fire extinguishing system, and thus effectively improves the fire safety of the electric bicycle charging shed.

[0043] In some preferred embodiments, the controller 3 is further configured to control the extinguishing agent replenishment component 4 to supply extinguishing agent to the water-based extinguishing agent storage tank when the total number of fire-related parameters reaching the corresponding preset fire judgment threshold is 1 and the extinguishing agent level information is less than or equal to a third preset level height, until the extinguishing agent level information reaches a fourth preset level height. The third preset level height is greater than the first preset level height, and the fourth preset level height is greater than the third preset level height and greater than or equal to a second preset level height. When the total number of fire-related parameters reaching the corresponding preset fire judgment threshold is 1, although the electric bicycle charging shed has not yet been determined to be a fire, there is a certain risk of fire. In this embodiment, the third preset level height is greater than the first preset level height, which means that this threshold is higher than the conventional low level alarm and replenishment threshold, so as to identify the possibility of insufficient extinguishing agent reserves earlier. When the total number of fire-related parameters that reach the corresponding preset fire judgment threshold is 1 and the extinguishing agent level information is less than or equal to the third preset level height (there is a risk of fire and the extinguishing agent inventory is at a medium to low level), the controller 3 will actively control the extinguishing agent replenishment component 4 to supply extinguishing agent to the water-based extinguishing agent storage tank until the extinguishing agent level information reaches the fourth preset level height. Since the fourth preset level height is greater than the third preset level height and greater than or equal to the second preset level height, this embodiment is equivalent to ensuring that the water-based extinguishing agent storage tank has sufficient extinguishing agent reserves when there is a risk of fire to deal with possible fires.

[0044] This embodiment effectively addresses the issue of insufficient extinguishing agent reserves in automatic fire suppression systems when responding to fire risks by introducing a replenishment mechanism based on a combination of potential fire hazards and moderately low liquid levels. Specifically, when a fire-related parameter reaches its corresponding preset fire judgment threshold, even if a fire in an electric bicycle charging shed is not determined, it indicates a certain fire risk. In this scenario, if the extinguishing agent level is only slightly higher than the conventional replenishment threshold (first preset liquid level height), the extinguishing agent may be depleted at a critical moment if the fire develops rapidly. This embodiment addresses this by setting a third preset liquid level height higher than the first preset liquid level height and triggering replenishment when a fire risk exists. This allows the automatic fire suppression system to promptly raise the extinguishing agent reserve to a safer level (fourth preset liquid level height), thereby providing more sufficient protection for subsequent fire suppression actions. This mechanism enables the automatic fire suppression system to preventively replenish the water-based fire extinguishing agent in the storage tank when there is a risk of fire, avoiding delays in fire suppression due to insufficient fire extinguishing agent during a fire, and ensuring that the fire suppression efficiency and effectiveness are not affected. Therefore, this embodiment can effectively improve the response capability and reliability of the automatic fire suppression system in response to fire, thereby effectively improving the fire safety of electric bicycle charging sheds.

[0045] As a specific implementation, the fourth preset liquid level height can be set to 90%. Assuming an electric bicycle charging shed, the first preset liquid level height is set to 30%, the second to 90%, and the third to 60%. The liquid level measuring component 5 detects that the extinguishing agent level in the water-based extinguishing agent tank is 50%. A cable temperature sensor 7 detects an abnormal temperature rise in a charging line, reaching its preset fire judgment threshold, while other fire detection sensors 1 (such as infrared / ultraviolet flame detectors, visual sensors, etc.) have not yet been triggered. Since the current extinguishing agent level of 50% is less than or equal to the third preset liquid level height of 60%, and the total number of fire-related parameters reaching the corresponding preset fire judgment threshold is 1, the controller 3 will control the extinguishing agent replenishment component 4 to supply extinguishing agent to the water-based extinguishing agent tank until the extinguishing agent level reaches the fourth preset liquid level height of 90%. In this way, when there is a fire risk but no fire has occurred, the extinguishing agent reserve in the water-based extinguishing agent tank is increased to a sufficient level, making full preparations for possible firefighting operations.

[0046] In some preferred embodiments, the automatic fire extinguishing system for electric bicycle charging sheds further includes a fire extinguishing agent heating component 6 and a temperature sensor 7. The fire extinguishing agent heating component 6 is installed on the water-based fire extinguishing agent storage tank and is used to heat the fire extinguishing agent stored in the tank. The temperature sensor 7 is installed on the tank and is used to collect temperature information of the fire extinguishing agent stored in the tank. The controller 3 is also used to control the fire extinguishing agent heating component 6 to heat the fire extinguishing agent stored in the tank when the temperature information is less than or equal to a first preset temperature, until the temperature information reaches a second preset temperature. The first preset temperature is greater than the freezing temperature of the fire extinguishing agent, and the second preset temperature is greater than the first preset temperature. The fire extinguishing agent heating component 6 in this embodiment can be understood as a device capable of transferring heat to the fire extinguishing agent in the water-based fire extinguishing agent storage tank. The fire extinguishing agent heating component 6 can be an existing electric heating rod, heating coil, or heat tracing cable. This embodiment can ensure that the fire extinguishing agent remains liquid in a low-temperature environment through the installation of the fire extinguishing agent heating component 6. In this embodiment, the temperature sensor 7 can be a thermistor, thermocouple, or platinum resistance thermometer, etc. This temperature sensor 7 is used to monitor the temperature of the extinguishing agent in the water-based extinguishing agent storage tank in real time and accurately. The first preset temperature in this embodiment refers to a temperature threshold higher than the freezing point of the extinguishing agent. For example, this embodiment sets the first preset temperature 2-5 degrees Celsius above the freezing point of the extinguishing agent. This embodiment is equivalent to initiating heating in the water-based extinguishing agent storage tank just before it solidifies, for preventative maintenance. The second preset temperature in this embodiment is higher than the first preset temperature, and this second preset temperature is preferably a suitable temperature that ensures the extinguishing agent has good flowability and spray performance.

[0047] This embodiment effectively solves the problem of extinguishing agent solidification in low-temperature environments by introducing an extinguishing agent heating component 6 and a temperature sensor 7. Specifically, the temperature sensor 7 continuously collects the temperature information of the extinguishing agent stored in the water-based extinguishing agent tank and transmits this information to the controller 3. When the temperature information received by the controller 3 is lower than or equal to a first preset temperature, it determines that the extinguishing agent is at risk of solidification and immediately controls the extinguishing agent heating component 6 to start heating. The extinguishing agent heating component 6 heats the extinguishing agent until the temperature information collected by the temperature sensor 7 reaches a second preset temperature, at which point the controller 3 stops heating. It is precisely because of this real-time temperature monitoring and automatic heating mechanism that the extinguishing agent is always kept in a suitable liquid state, ensuring its availability in emergency situations. Therefore, this embodiment can effectively prevent the extinguishing agent from solidifying in low-temperature environments, ensuring that the automatic fire extinguishing system can reliably perform fire extinguishing actions under any environmental conditions. Thus, this embodiment can effectively improve the environmental adaptability and reliability of the automatic fire extinguishing system, thereby effectively improving the fire safety level of electric bicycle charging sheds and avoiding fire extinguishing failure caused by the solidification of the extinguishing agent, thereby further reducing the risk of personal injury and property loss.

[0048] In some preferred embodiments, the process of analyzing whether a fire has occurred in the electric bicycle charging shed based on all fire-related parameters and their corresponding preset fire judgment thresholds is as follows: B1. Obtain the current environmental and operational status information of the electric bicycle charging shed; B2. Select one fire judgment logic group from multiple preset fire judgment logic groups based on environmental status information and operational status information. The fire judgment logic group includes preset fire judgment thresholds corresponding to different types of fire-related parameters. B3. Analyze whether a fire has occurred in the electric bicycle charging shed based on all fire-related parameters and their corresponding preset fire judgment thresholds.

[0049] The environmental status information in this embodiment can be understood as data reflecting the external or internal environmental conditions of the electric bicycle charging shed. This environmental status information may include ambient temperature, ambient humidity, wind speed, light intensity, seasonal information, and time period information. This embodiment can provide an external environmental background for fire judgment by acquiring environmental status information, so that the automatic fire extinguishing system can distinguish between normal environmental fluctuations and abnormal fire signals. The operational status information in this embodiment can be understood as data reflecting the operating status of the equipment inside the electric bicycle charging shed. This operational status information may include the number of electric bicycles currently charging, total charging power, charging pile load status, and charging time. This embodiment can provide an internal operational background for fire judgment by acquiring operational status information, so that the automatic fire extinguishing system can identify parameter changes caused by normal or abnormal operation. The fire judgment logic group in this embodiment refers to a set of preset fire judgment rules for different environmental and operational conditions. For example, the fire judgment logic group includes threshold groups for high-temperature environments and high-load charging, threshold groups for low-temperature environments and high-load charging, threshold groups for low-load charging, and threshold groups for low-load charging. Each logic group contains preset fire judgment thresholds corresponding to different types of fire-related parameters. For example, for temperature sensor 7, its threshold may be set higher in the logic group corresponding to high temperature environment and high load charging, while it may be set lower in the logic group corresponding to low temperature environment and low load charging. This embodiment is equivalent to enabling the fire judgment process to dynamically adjust the judgment criteria according to the actual situation, so as to improve the accuracy and adaptability of the judgment.

[0050] This embodiment effectively addresses the limitations of fixed threshold judgments in dynamic environments by acquiring environmental and operational status information before fire detection and dynamically determining a preset fire detection threshold based on this information. Specifically, in step B1, the system acquires the current environmental and operational status information of the electric bicycle charging shed, which comprehensively reflects the real-time conditions inside and outside the shed. Subsequently, in step B2, the controller 3 intelligently selects the logic group that best matches the current situation from multiple preset fire detection logic groups based on this real-time acquired status information. This dynamic selection mechanism enables the controller 3 to analyze all fire-related parameters based on the threshold that best matches the current actual environment and operational status, thereby determining whether a fire has occurred in the electric bicycle charging shed. This avoids false alarms caused by changes in environment or operational status in non-fire situations and allows for a more accurate and timely response when a real fire occurs. Therefore, this embodiment effectively improves the accuracy and reliability of fire detection by dynamically adjusting the fire detection threshold based on the real-time environmental and operational status information of the electric bicycle charging shed. As a result, this embodiment can effectively reduce the occurrence of false alarms, thereby further enhancing the fire safety protection capability of the electric bicycle charging shed.

[0051] In some preferred embodiments, a specific example is given below. During the high-temperature period of summer, a large number of electric bicycles are charging in the electric bicycle charging shed. At this time, the controller 3 first obtains environmental status information, such as an ambient temperature of 35°C and an ambient humidity of 60%; it also obtains operating status information, such as the number of electric bicycles charging being 50 and the total charging power reaching 80% of the maximum load. Based on this information, the controller 3 determines that the current situation is a "high temperature and high load" scenario. Subsequently, the controller 3 selects the logic group for the "high temperature and high load" scenario from the preset fire judgment logic group. In this logic group, for example, the preset fire judgment threshold of the temperature sensor 7 may be set to 70°C (higher than the conventional 60°C) to avoid false alarms caused by high ambient temperature and charging heat; while the preset fire judgment threshold of the smoke sensor may be set more strictly to ensure that smoke signals can still be detected in time under high temperature background. Next, the controller 3 analyzes the fire-related parameters collected by the fire detection sensor 1 according to these dynamically adjusted thresholds, thereby making a more accurate fire judgment. During periods of low winter temperatures, only a few electric bicycles are charging in the charging shed. At this time, controller 3 acquires environmental status information, such as an ambient temperature of 5°C and an ambient humidity of 80%. It also acquires operational status information, such as the number of electric bicycles charging being 5 and the total charging power being low. Based on this information, controller 3 determines that the current scenario is a "low temperature, low load" scenario. Controller 3 selects a logic group specific to the "low temperature, low load" scenario from a preset fire detection logic group. In this logic group, for example, the preset fire detection threshold for temperature sensor 7 might be set to 50°C (lower than the usual 60°C) to improve sensitivity to abnormal temperature increases; while the preset fire detection threshold for the flame sensor might remain unchanged. Next, controller 3 analyzes the fire-related parameters collected by fire detection sensor 1 based on these dynamically adjusted thresholds, thereby ensuring timely and accurate detection of fire hazards even in low-temperature environments.

[0052] In some preferred embodiments, multiple fire detection sensors 1 that collect the same type of fire-related parameters are evenly distributed on the electric bicycle charging shed. This embodiment is equivalent to deploying more than one fire detection sensor 1 on the electric bicycle charging shed for a specific fire-related parameter (such as temperature, smoke concentration, or flame signal). For example, multiple temperature sensors 7 can be deployed to monitor temperature changes in different areas, or multiple smoke sensors can be deployed to cover a wider smoke diffusion range. This embodiment provides redundancy by setting the number of fire detection sensors 1 of the same type to multiple, ensuring that even if a single sensor fails, the fire-related parameter of that type can still be effectively collected, and at the same time, the changes of the parameter in different locations can be perceived more precisely. This embodiment ensures that multiple fire detection sensors 1 of the same type can cover all areas of the electric bicycle charging shed and avoid detection blind spots by evenly distributing them on the shed. For example, these sensors can be arranged in a preset grid, linear or ring pattern so that the distance from any point to the nearest sensor of the same type is within an acceptable range, thereby ensuring comprehensive and blind-spot-free monitoring of fire-related parameters throughout the charging shed area. This embodiment maximizes the detection coverage by evenly distributing multiple fire detection sensors 1 of the same type on the electric bicycle charging shed, thereby improving the early warning capability and positioning accuracy of fires. This embodiment significantly improves the comprehensiveness and reliability of fire detection by setting up multiple fire detection sensors 1 of the same type and distributing them evenly. Specifically, when a fire occurs in an electric bicycle charging shed, due to the uncertainty of the fire's location and spread path, a single fire detection sensor 1 may not be able to capture the fire signal in time. Therefore, this embodiment, through the even distribution of multiple sensors of the same type, ensures that at least one or more sensors of that type can detect the corresponding fire-related parameters in a timely manner when a fire occurs at any location. This embodiment can utilize data from multiple sensors of the same type for cross-validation and fusion, thereby effectively reducing the false alarm rate and improving the accuracy of fire judgment. For example, when one temperature sensor 7 detects an abnormally high temperature, another nearby temperature sensor 7 can also provide auxiliary data, enabling the controller 3 to more reliably determine the authenticity of the fire.

[0053] In some preferred embodiments, the fire detection sensor 1 includes a cable temperature sensor 7, an infrared and ultraviolet flame detector, a visual sensor, a photoelectric smoke detector, and a heat detector. In this embodiment, the cable temperature sensor 7 is used to monitor the temperature of the charging cables inside the electric bicycle charging shed in real time to detect localized overheating caused by cable overload, short circuits, or poor contact. The fire-related parameter it collects is the cable temperature. The cable temperature sensor 7 can be an existing thermistor, thermocouple, or infrared temperature measurement module, etc., and is directly attached to the charging cable. In this embodiment, the infrared and ultraviolet flame detector is used to detect the infrared and ultraviolet radiation generated during flame combustion. The fire-related parameter it collects is the flame radiation intensity. This infrared and ultraviolet flame detector can quickly respond to open flames and can be installed on the top or side wall of the electric bicycle charging shed. In this embodiment, the visual sensor can be an existing high-definition camera. This visual sensor is used to collect image or video information inside the electric bicycle charging shed and analyzes the presence of fire signs such as smoke, flames, abnormal lighting, or abnormal human behavior using image processing technology. The fire-related parameter it collects is visual image features. The photoelectric smoke detector of this embodiment is used to detect smoke particles generated in the early stages of a fire. The fire-related parameter it collects is smoke concentration. Specifically, when smoke enters the optical labyrinth inside the detector, it scatters light, thereby triggering an alarm. This photoelectric smoke detector has high sensitivity to smoldering fires and is preferably installed on the top of an electric bicycle charging shed. The heat detector of this embodiment is used to detect abnormal increases in ambient temperature, and the fire-related parameter it collects is ambient temperature.

[0054] As can be seen from the above, the automatic fire extinguishing system for electric bicycle charging sheds provided in this application automatically identifies fire-related parameters of multi-source fires and directly controls the fire extinguishing actuator 2 to perform fire extinguishing actions when a fire is detected, thus eliminating the reliance on manual intervention in the fire extinguishing system. Therefore, this application can achieve a high degree of automation and real-time response in fire identification and fire extinguishing. This automated fire extinguishing mechanism can greatly shorten the time interval from the occurrence of a fire to the execution of the fire extinguishing action, thereby effectively curbing the initial spread of the fire. Therefore, this application can effectively reduce the risk of personal injury and property loss, thereby effectively improving the fire safety level of electric bicycle charging sheds.

When a fire is detected in the electric bicycle charging shed, an alarm message is generated and sent based on the preset location information of the electric bicycle charging shed, and the fire extinguishing actuator 2 is controlled to perform fire extinguishing actions.
