Description

Technical Field

[0001] The present invention relates to the field of new energy charging devices, and particularly to a new energy charging shed and an intelligent fire control method and device. Background Art

[0002] With the increasing requirements of society for environmental protection and energy conservation, new energy vehicles have received more and more attention from the government and manufacturers. However, since new energy vehicles use batteries and motors as the driving power source, there are always some potential safety hazards in the actual use process. Especially in recent years, there has been an explosive growth demand in the fields of new energy vehicles and energy storage, and news of electric vehicle spontaneous combustion has been reported frequently. This is mainly because the liquid electrolyte of the charging battery is flammable and explosive, and it is easy to trigger "thermal runaway" during long-term use, causing the battery temperature to rise rapidly to 400 - 1000 °C, and then accidents such as fire and explosion occur.

[0003] Although there are some technical solutions in the prior art that collect the environmental temperature of the charging shed to determine whether a fire occurs and isolate and extinguish it, usually the real-time temperature collected by any temperature sensor in the charging area is directly compared with a fixed alarm temperature. In the case of a fire that has already occurred, if the alarm temperature remains the same as the alarm temperature when there is no fire, there is a technical problem that the actual fire state of the charging spaces in the charging shed, especially the adjacent parking spaces to the fire, cannot be accurately reflected. Summary of the Invention

[0004] The present invention provides a new energy charging shed and an intelligent fire control method and device, which solve the above-mentioned technical problems.

[0005] In the first aspect of the embodiments of the present invention, an intelligent fire control method for a new energy charging shed is provided. The parking space covered by the new energy charging shed is divided into a plurality of charging spaces by a number of fire partitions arranged at intervals. An infrared temperature sensor is provided at the roof of each charging space, and a charging control device, a fire protection device, and an alarm device are provided in the new energy charging shed. The method includes the following steps:

[0006] Step 1, obtain target infrared temperature sensor information according to the startup state of the fire protection device, collect the real-time temperature values of at least one target infrared temperature sensor, and calculate the mean value of the real-time temperature values to generate the average environmental temperature corresponding to each collection moment;

[0007] Step 2, generate a fire alarm value corresponding to the collection moment according to the average environmental temperature;

[0008] Step 3, if the real-time temperature value of any one of the infrared temperature sensors is greater than the fire alarm value, generate a preset power-off instruction, a preset audible and visual alarm instruction, and a first fire control instruction and send them to the corresponding devices.

[0009] In a second aspect of the embodiments of the present invention, a computer-readable storage medium is provided, storing a computer program, which when executed by a processor, implements the intelligent fire control method for the new energy charging shed described above.

[0010] In a third aspect of the embodiments of the present invention, an intelligent fire control device for a new energy charging shed is provided. The intelligent fire control device includes an ambient temperature calculation module, a warning temperature calculation module, and a fire control module.

[0011] The ambient temperature calculation module is used to obtain target infrared temperature sensor information according to the startup state of the fire protection device, collect the real-time temperature values of at least one target infrared temperature sensor, and calculate the average value of the real-time temperature values to generate the average ambient temperature corresponding to each collection moment.

[0012] The warning temperature calculation module is used to generate the fire alarm value corresponding to the collection moment according to the average ambient temperature.

[0013] The fire control module is used to, if the real-time temperature value of any one of the infrared temperature sensors is greater than the fire alarm value, generate a preset power-off instruction, a preset audible and visual alarm instruction, and a first fire control instruction and send them to the corresponding devices.

[0014] In a fourth aspect of the embodiments of the present invention, a new energy charging shed is provided. The parking space covered by the new energy charging shed is divided into multiple charging spaces by a number of fire partitions arranged at intervals. Infrared temperature sensors are arranged at the shed tops of each charging space, and a charging control device, a fire protection device, an alarm device, and the intelligent fire control device are arranged in the new energy charging shed.

[0015] The beneficial effects of the present invention are as follows: The present invention provides a new energy charging shed, an intelligent fire control method, and a device. By the startup state of the fire protection device, that is, the fire situation in the charging shed, the real-time temperature of at least one target infrared temperature sensor is collected to calculate the average ambient temperature. Compared with the method of directly measuring the ambient temperature, it can more accurately sense the overall temperature situation in the charging shed. On this basis, a more reasonable fire alarm value is obtained, improving the effectiveness of the fire control process in the charging shed and the safety of the charging process.

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0022] It should be noted that if there is no conflict, the various features in the embodiments of the present invention can be combined with each other, and all are within the scope of protection of the present invention. In addition, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from the module division in the device or the flowchart. Furthermore, the terms "first", "second", "third", etc. used in the present invention do not limit the data and execution order, but only distinguish the same items or similar items with basically the same functions and effects.

[0023] Figure 1 It is a schematic flowchart of an intelligent fire control method for a new energy charging shed provided in Embodiment 1.

[0024] It can be understood that the parking space covered by the new energy charging shed in this embodiment is divided into multiple charging spaces by a number of fire partitions arranged at intervals. Infrared temperature sensors are installed at the top of the shed for each charging space. At the same time, a charging control device for charging management of all charging interfaces in the charging shed, a fire fighting device for suppressing fires in the multiple charging spaces, and an alarm device for sound and light warning are provided in the new energy charging shed.

[0025] Specifically, the new energy charging shed can be a solar charging shed, which consists of a steel structure shed, photovoltaic panels, photovoltaic charging and reverse control integrated equipment, energy storage batteries, charging ports, 4G / 5G data communication modules, infrared temperature sensors, intelligent fire control devices, charging control devices, fire fighting devices, alarm devices, etc. The fire fighting devices include fire water tanks, fire water pumps, pipes, solenoid valves and high-pressure nozzles, etc.

[0026] In a more specific embodiment, the photovoltaic panel is connected to the photovoltaic charging and reverse control integrated device through a cable, and the photovoltaic charging and reverse control integrated device is connected to the energy storage battery. The electric energy converted by the photovoltaic battery is transmitted to the energy storage battery for storage and use after voltage boosting, voltage stabilization and voltage transformation. At the same time, the charging shed is provided with a plurality of parking spaces for charging electric vehicles or electric vehicles, and each charging parking space is separated by a number of fire partitions arranged at intervals. Specifically, the steel scaffolding of the charging parking space is equipped with charging interfaces that are consistent with the number of parking spaces. Each charging interface is connected to the charging control device through a cable, and the charging control device is responsible for charging management of each charging interface. The charging control device is also connected to the photovoltaic charging and reverse control integrated device, which provides electric energy and automatically switches between photovoltaic energy, energy storage batteries and city electricity according to pre-set algorithm rules.

[0027] In a preferred embodiment, the steel frame columns of the charging shed are connected through a steel fire water tank, and a fire water pump for spraying fire extinguishing is installed in the compartment of the steel water tank, and the fire water pump is connected to the intelligent fire control device. The intelligent fire control device is connected to multiple infrared temperature sensors and multiple high-pressure resistant electromagnetic valves. The infrared temperature sensor is installed in the roof of the shed directly above the charging parking space, and multiple infrared temperature sensors are arranged in sequence. The number of installed infrared temperature sensors is consistent with the number of charging parking spaces, and is used to monitor the temperature changes of charging vehicles in real time.

[0028] Exemplarily, the fire-fighting device includes a plurality of high-pressure water mist nozzles arranged in the charging shed. For example, one or more high-pressure water mist nozzles are installed on the roof above the charging parking space, and the on and off of the fire-fighting water spray is controlled by the solenoid valve installed at the rear end of the nozzle. In addition, at least one fan-shaped high-pressure water mist nozzle is installed on both sides of the charging parking space, and the on and off of the fire-fighting water spray is controlled by two solenoid valves installed at the rear end of the nozzle. In a preferred embodiment, the information of the infrared temperature sensor at each charging parking space (such as the number, etc.) can be associated with the information of multiple solenoid valves at the corresponding positions (such as the solenoid valve at the roof and the solenoid valves on both sides), and the association results are saved, so that in the control process, only the association result needs to be queried to control the target solenoid valve of the starting parking space or the target adjacent parking space, thereby controlling the water spraying state and improving the efficiency of intelligent fire control.

[0029] like Figure 1As shown in the figure, the intelligent fire control method of this embodiment includes the following steps:

[0030] Step 1: Obtain the target infrared temperature sensor information according to the startup state of the fire-fighting device, collect the real-time temperature values of at least one target infrared temperature sensor, and calculate the mean value of the real-time temperature values to generate the average ambient temperature corresponding to each acquisition moment;

[0031] Step 2: Generate the fire alarm value corresponding to the acquisition moment according to the average ambient temperature;

[0032] Step 3: If the real-time temperature value of any one of the infrared temperature sensors is greater than the fire alarm value, generate a preset power-off instruction, a preset audible and visual alarm instruction, and a first fire control instruction and send them to the corresponding device.

[0033] It can be understood that when the real-time temperature value of any one of the infrared temperature sensors is greater than the fire alarm value, it indicates that a fire has occurred in the charging shed. At this time, a preset power-off instruction is first generated and sent to the charging control device. This preset power-off instruction is used to drive the charging control device to cut off the power output of all charging ports, or if any charging port is already in the disconnected state, then keep the disconnected state unchanged, so as to prevent circuit short-circuiting during fire extinguishing or suppressing the spread of the fire, and further expanding the fire. At the same time, a preset audible and visual alarm instruction is generated and sent to the alarm device, so as to control the alarm device to emit obvious beeping sounds, color changes, or warning texts, etc., to remind passers-by to pay attention to personal safety and call the fire alarm. In addition, a first fire control instruction is also generated and sent to the fire-fighting device to drive the fire-fighting device to take corresponding measures to extinguish the fire and suppress the spread of the fire.

[0034] The above embodiment provides an intelligent fire control method for a new energy charging shed. By the startup state of the fire-fighting device, that is, the fire state in the charging shed, the real-time temperature of at least one target infrared temperature sensor is collected to calculate the average ambient temperature. Compared with the method of directly measuring the ambient temperature, it can more accurately sense the overall temperature situation in the charging shed. On this basis, a more reasonable fire alarm value is obtained, improving the effectiveness of the fire control process in the charging shed and the safety of the charging process.

[0035] The following uses specific embodiments to elaborate on each step of the above method in detail.

[0036] In a specific embodiment, in Step 1, when the fire-fighting device is in the unstarted state, in other words, when there is no fire in the charging shed, the average ambient temperature is calculated according to the real-time temperature values of all infrared temperature sensors. For example, the average ambient temperature can be the mean value or weighted mean value of the real-time temperatures of all infrared temperature sensors.

[0037] In a preferred embodiment, when the fire-fighting device is in the activated state, it indicates that a fire has occurred in the charging shed. At this time, in order to improve the fire detection and spread suppression effects, the infrared temperature sensor at the location of the fire cannot be used anymore. Specifically, in this state, the steps of generating the average ambient temperature corresponding to each acquisition moment include the following:

[0038] Collect preset parameter values and generate the target number of adjacent parking spaces according to the preset parameter values;

[0039] Obtain the information of the fire-starting parking space and generate the target adjacent parking space information according to the target number of adjacent parking spaces;

[0040] Exclude the fire-starting parking space and the target adjacent parking spaces from all charging parking spaces according to the fire-starting parking space information and the target adjacent parking space information to generate the reference parking space information;

[0041] Obtain the real-time temperature values of at least one reference parking space and calculate the average value of the real-time temperature values to generate the average ambient temperature corresponding to the acquisition moment.

[0042] In the above preferred embodiment, the fire-starting parking space refers to the charging parking space in the new energy charging shed whose real-time temperature value is greater than the fire alarm value. For example, there are 10 infrared temperature sensors installed in the charging shed, and the temperature values they collect are N 1 —N 10 . When the fire-fighting device is not activated, the average ambient temperature = (N 1 +N 2 +N 3 +……+N 10 ) / 10. Then, the fire alarm value is calculated based on this average ambient temperature. When the temperature of any one of the infrared temperature sensors exceeds the fire alarm value, the fire-fighting device activates the solenoid valve corresponding to this infrared temperature sensor to spray water for cooling and fire extinguishing.

[0043] After the fire-fighting device is activated, this embodiment will recalculate the average ambient temperature and the fire alarm value. For example, if the target number of adjacent parking spaces obtained according to the preset parameter values is 2, then when the temperature of N 5 exceeds the fire alarm value, the sampling data of N 4 , N 5 , N 6 will no longer be counted and used for calculating the new average ambient temperature. At this time, the new average ambient temperature = (N 1 +N 2 +N 3 +N 7 +N 8 +N 9 +N 10 ) / 7. Then, a new fire alarm value is calculated based on the new average ambient temperature. When it is detected that N 4or N 6 When the temperature data of any one of the infrared temperature sensors is greater than the new fire alarm value, immediately open the solenoid valves of the fan-shaped water mist nozzles on both sides of the fire-starting parking space to spray water for isolation, prevent the fire from spreading to the left and right, and at the same time cool the adjacent electric vehicles to prevent fires, further improving the safety protection effect.

[0044] It can be understood that the distribution state of electric vehicles and weather conditions, such as wind, rain, etc., have a very large impact on the spread of the fire, and thus will also affect the selection result of the target adjacent parking spaces in this embodiment. Specifically, in a preferred embodiment, the preset parameter values include weather state parameter values, fire location information (such as fire height information), and real-time parking state information of electric vehicles, etc. At this time, the number of target adjacent parking spaces is generated according to the preset parameter values, specifically:

[0045] Obtain the weather state parameter value, and generate a first correction coefficient according to the weather state parameter value;

[0046] Obtain the fire location information and the real-time parking state information of all charging parking spaces, and generate a second correction coefficient according to the fire location information and the real-time parking state information;

[0047] Adjust the reference quantity value according to the first correction coefficient and the second correction coefficient to generate the number of target adjacent parking spaces as follows:

[0048] Q1 = X1 * X2 * Q,

[0049] where X1 is the first correction coefficient, X2 is the second correction coefficient, Q is the reference quantity value, and Q1 is the number of target adjacent parking spaces.

[0050] In a specific embodiment, the reference quantity value is set to 2. The real-time parking state information includes at least one or more of the vehicle type (electric vehicle or electric bicycle), the number of vehicles (0, 1 or more), the vehicle charging state (charging or not charging), and the vehicle battery installation position (installation height) parked on each charging parking space. Here, X1 and X2 can be set according to big data or the actual use effect of the solution of the present invention.

[0051] It can be understood that in one embodiment, the fire alarm value is the sum of the calculated average ambient temperature and a set value. In other words, when the temperature collected by an infrared temperature sensor exceeds the average ambient temperature by a large amount, such as exceeding 100 °C, it can be determined that a fire has occurred at the corresponding charging parking space. In a specific embodiment, this set value can be a constant value, such as a constant of 100 °C. In order to improve the actual application effect, a variable value can also be used, such as after a fire actually occurs, the set value is adjusted to 50 °C.

[0052] In a preferred embodiment, generating the fire alarm value corresponding to the acquisition moment specifically includes:

[0053] Collecting historical fire data corresponding to vehicle clusters with different quantities, where the historical fire data includes the burning duration of a single vehicle, the burning interval duration between adjacent vehicles, the fire fighting duration, and so on.

[0054] Then, a mapping relationship table is established based on the historical fire data. The mapping relationship table includes the mapping relationship between the fire duration and the fire fighting difficulty coefficient. When the fire duration is less than the preset duration, the greater the fire duration, the greater the fire fighting difficulty coefficient; when the fire duration is greater than or equal to the preset duration, it indicates that it is almost burned out. At this time, the greater the fire duration, the smaller the fire fighting difficulty coefficient.

[0055] Collect the current fire duration and query the mapping relationship table. Generate the corresponding target fire fighting difficulty coefficient according to the numerical range where the current fire duration is located. Finally, adjust the preset temperature value according to the target fire fighting difficulty coefficient to generate the current alarm reference value, and calculate the sum of the average ambient temperature and the current alarm reference value. The calculation result is the fire alarm value corresponding to the current moment, thereby further improving the actual use effect of the solution of the present invention.

[0056] In a preferred embodiment, the first fire control instruction is used to drive the fire fighting device to carry out fire extinguishing on at least one of the fire-starting parking spaces according to a preset grouped emergency plan and / or control the spread of the fire to the target adjacent parking spaces. Specifically, the fire spread speeds of adjacent parking spaces at different interval distances are different. Therefore, the target adjacent parking spaces can be divided into different danger levels according to the interval distance from the fire-starting parking space. At this time, the preset grouped emergency plan specifically includes the following steps:

[0057] For the fire-starting parking space and the first target adjacent parking spaces with a danger level higher than the first preset level, control at least one high-pressure water mist nozzle installed at the shed top and at least one high-pressure water mist nozzle installed on both sides of the parking space to carry out water spraying isolation;

[0058] For the second target adjacent parking spaces with a danger level not higher than the first preset level but higher than the second preset level, control at least one high-pressure water mist nozzle installed on both sides of the parking space to carry out water spraying isolation;

[0059] For the third target adjacent parking spaces with a danger level lower than or equal to the second preset level, control at least one high-pressure water mist nozzle on the target side to carry out water spraying isolation. In this way, the fire fighting water of the steel water tank can be used more effectively, preventing waste or avoiding the situation of water shortage during the fire suppression process.

[0060] It is understandable that in a preferred embodiment, a flame sensor and / or a camera device, such as an AI intelligent camera, is also installed below the top of the steel shed. The charging site in the charging shed is monitored in real time all-weather through the camera device to prevent the failure of the infrared temperature sensor from failing to detect a fire in a timely manner. At this time, the intelligent fire-fighting method further includes the following steps:

[0061] Periodically collect real-time images of the new energy charging shed through the camera device;

[0062] When it is determined that a fire has occurred in the charging shed through the real-time image or the flame sensor, identify the fire-starting parking space, generate a preset power-off instruction, and push the on-site video to the remotely connected cloud platform;

[0063] Obtain the real-time status of the fire-fighting device. If any high-pressure water mist nozzle of the fire-fighting device is not opened, generate a second fire control instruction. The second fire control instruction is used to open the solenoid valves of all high-pressure water mist nozzles corresponding to the fire-starting parking space to ensure that fire sprinklers can be activated to extinguish the fire and prevent the spread of the fire even when the infrared temperature sensor is disabled. At the same time, all the audible and visual alarm data, on-site videos, and disposal data will be recorded in the database of the cloud platform in the form of event logs for later reference.

[0064] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

[0065] The embodiment of the present invention also provides a computer-readable storage medium storing a computer program. When the computer program is executed by a processor, the intelligent fire control method for the new energy charging shed described above is implemented.

[0066] Figure 2 It is a schematic structural diagram of the intelligent fire control device for the new energy charging shed provided in Embodiment 2, as Figure 2 shown. The intelligent fire control device includes an ambient temperature calculation module 100, an early warning temperature calculation module 200, and a fire control module 300.

[0067] The ambient temperature calculation module 100 is used to obtain target infrared temperature sensor information according to the startup state of the fire-fighting device, collect the real-time temperature values of at least one target infrared temperature sensor, and calculate the mean value of the real-time temperature values to generate the average ambient temperature corresponding to each acquisition moment.

[0070] The above embodiments provide an intelligent fire control device for a new energy charging shed. By the startup state of the fire control device, that is, the fire condition in the charging shed, the real-time temperatures of at least one target infrared temperature sensor are collected to calculate the average ambient temperature.

[0071] In a preferred embodiment, the ambient temperature calculation module 100 specifically includes:

[0080] Q1 = X1 * X2 * Q

[0081] Where X1 is the first correction coefficient, X2 is the second correction coefficient, Q is the reference quantity value, and Q1 is the number of target adjacent parking spaces.

[0082] In a preferred embodiment, the early warning temperature calculation module 200 specifically includes:

[0083] An acquisition unit for acquiring historical fire data corresponding to vehicle clusters with different quantities;

[0091] In a preferred embodiment, the fire control module 300 is further configured to periodically collect real-time images of the new energy charging shed through the imaging device. When it is determined that a fire breaks out in the charging shed through the real-time images or the flame sensor, it identifies the parking space where the fire occurs, generates a preset power-off instruction, and pushes the on-site video to the remotely connected cloud platform; and is configured to obtain the real-time status of the fire-fighting device. If any of the high-pressure water mist nozzles of the fire-fighting device are not opened, a second fire control instruction is generated, and the second fire control instruction is used to open the solenoid valves of all the high-pressure water mist nozzles corresponding to the parking space where the fire occurs.

Compared with the method of directly measuring the ambient temperature, it can more accurately sense the overall temperature situation in the charging shed. On this basis, a more reasonable fire alarm value is obtained, improving the effectiveness of the fire control process in the charging shed and the safety of the charging process.
