Description

TECHNICAL FIELD

[0001] The present invention relates to a fire prevention system using a thermal imaging camera or a thermal imaging sensor, and more specifically, it can predict in advance a fire occurrence of a space where a battery is placed, such as an electric vehicle charging station. BACKGROUND

[0002] Recently, as the use of electric vehicles increases, many electric vehicle charging stations are installed, and accordingly, the production of batteries is also showing a tendency to greatly increase.

[0003] The electric vehicle charging station includes a wireless charging pole or a wired charging pole, and a space where a vehicle is parked. An electric vehicle charger (a wireless charger or a wired charger) is electrically connected to a connector connected to an inlet of an electric vehicle through a cable as a medium to supply power to the charger (see Registered Patent No. 10-2465617 (hereinafter referred to as conventional technology 1).

[0004] In addition, an electric vehicle using an electric vehicle charging station is equipped with a battery, and a thermal explosion can occur on the lithium battery of the electric vehicle, and it is very difficult to extinguish the fire.

[0005] Therefore, like the battery of the electric vehicle, the space where the battery is placed always has a risk of fire.

[0006] The conventional technology, Registered Patent No. 10-2680197 (hereinafter referred to as conventional technology 2), is about a salt-proof film for extinguishing a fire at an electric vehicle charging station, and more specifically, when a fire occurs at an electric vehicle charging station, a salt-proof film installed at an upper portion of the electric vehicle spreads to isolate a fire field, prevents the spread of flames, and a fire extinguishing agent is sprayed inside the salt-proof film to function to extinguish the fire. The agent sprayed inside the salt-proof film is stored in a storage function, and if a certain amount of fire extinguishing agent is discharged, the function to extinguish the fire is achieved through the salt-proof film outside. That is, it is possible to reduce the amount of fire extinguishing agent sprayed inside, thereby reducing the use amount of the fire extinguishing agent.

[0007] However, the conventional technology is about a fire occurrence and response, and there is a problem that it can evolve into a huge disaster when it cannot be initially responded to after the fire occurs.

[0031] The advantages and features of this invention, as well as the methods for implementing them, will become clear from the accompanying drawings and detailed implementation examples. However, this invention will be embodied in different forms and is not limited to the embodiments described below. These embodiments are intended only to complete the introduction of the invention and to fully inform those skilled in the art of the scope of the invention, which is defined only by the scope of the claims.

[0032] When we say "connected" to a part, this includes not only "direct connection" (including communicable electrical connection) but also "indirect connection" (including communicable electrical connection) with other components in between.

[0033] Figure 1 This is a schematic drawing illustrating a fire prevention system according to an embodiment of the present invention. Figure 2 These are drawings illustrating the first sensing unit, second sensing unit, and server of a fire prevention system. Figure 3 These are drawings illustrating the first sensory unit. Figure 4 These are drawings illustrating additional embodiments of the present invention.

[0034] According to one example of the present invention, the fire prevention system S (a fire prevention system using a thermal imaging camera or thermal imaging sensor) is designed to predict in advance the occurrence of fires in a battery storage space (hereinafter referred to as the storage space), such as an electric vehicle charging station, in order to suppress the occurrence of fires and to quickly carry out initial response. For ease of explanation, it is referred to as "this system".

[0035] As Figure 1 And Figure 2 As shown in the system (fire prevention system S) includes a thermal sensing part 1 and a comparison part.

[0036] The thermal sensor 1 is installed at an electric vehicle charging station, including a thermal imaging camera (for example, ACT-F200-B or ACT-200-D) or a thermal imaging sensor (for example, ACT-F250Q).

[0037] The thermal imager or thermal imaging sensor calculates the temperature by measuring infrared energy (radiant heat), usually including a lens, a thermal sensor, an electronic processing device, etc.

[0038] Radiant energy (infrared energy) passes through the lens, and filtered infrared light converges on the thermal sensor. At this time, the electronic processing device converts the infrared energy into an electrical signal, converts the electrical signal into a numerical value, calculates the temperature, and displays it in color on the display.

[0039] The principle of the thermal imager or thermal imaging sensor has been announced, and more specific descriptions will be omitted.

[0040] The thermal sensor 1 is provided with a placement space for placing a battery, measures the temperature by measuring infrared energy, and transmits it to the comparison part described later. The thermal sensing part 1 will be described in more detail in the following description.

[0041] The comparison part can be a configuration included in the system server 2.

[0042] The server 2 can adopt various control configurations or computing devices known to those skilled in the art (for example, computers, processors, and various electronic devices or electronic modules). For example, the server 2 can be a configuration that transmits signals or commands generated according to programs or algorithms (artificial intelligence algorithms, etc.) contained therein to the notification book 115, the warning light 116, etc. described later. For example, the server 2 can be independent of the notification book 115, the warning light 116, etc. and connected to the notification book 115, the warning light 116, etc. through a wired or wireless connection.

[0043] The server 2 can include or not include one or more of the following thermal imaging storage and real storage.

[0044] The comparison part receives a measurement signal (measurement data) regarding the measured temperature from the thermal sensing part, and can generate an alarm signal if the measured temperature exceeds a set reference temperature.

[0045] The system can include a notification light 115 that receives the alarm signal and outputs an alarm sound, and a warning light 116 that receives the alarm signal and emits light.

[0046] If the comparison section generates an alarm signal, the server of the present system can send SMS data or the like written with an adoring word to the client.

[0047] The set reference temperature can be lower than the fire temperature of the electric vehicle (lower than the battery fire temperature), so that the present system can predict the fire of the vehicle in advance, prevent the fire from occurring, and quickly respond to the fire at the initial stage to minimize the loss caused by the fire.

[0048] As shown in Figure 1 and Figure 2 The heat sensor 1 can include a first sensor 111 and a first sensor 11, which includes a first thermal imager or a first thermal imager for measuring the infrared energy of the placement space, and a real imager 112 (for example, CCTV) for photographing the charging space. The first sensing part 11 can be in the form of a streaming camera or a turntable camera including the first measuring part 111 and the real sensing camera 112.

[0049] In addition, the heat sensor 1 can include a second thermal imager, and can also include a second sensor 12 for measuring the infrared energy radiated from the plug (connector connection part of the charger 4) or the vehicle battery of the vehicle parked in the area (for example, parking area) of the placement space.

[0050] That is, the heat sensing part 1 includes a first sensing part 11 and a second sensing part 12, and can simultaneously grasp the temperature of the entire placement space and the temperature of the inlet or outlet of the individual vehicle parked in the placement space for charging or the battery.

[0051] The present system can include a display that measures (photographs) the transmitted thermal image data on the first sensor 11 and receives and outputs the thermal image data measured (photographed) and transmitted on the second sensor 12.

[0052] The first sensor 11 is configured to grasp the temperature of the entire placement space, and can grasp the location of the area with a higher temperature in real time, and the second sensor 12 is configured to precisely measure the battery or the part of the individual vehicle that needs precise temperature measurement.

[0053] The thermal imager of the first sensor 11 generally has an ROI (Region of Interest) function, and can measure the infrared energy of the placement space by area (for example, by parking space).

[0054] The first sensing part 11 includes a real camera, and the video data photographed by the real camera can be transmitted to an output device (for example, a display) for output, so that the placement space can be more accurately monitored.

[0055] The system can include a thermal image storage that receives and stores the thermal image data from the first thermal imager 11, and the thermal image data recorded from the second thermal imager.

[0056] The thermal imaging camera typically generates thermal imaging data (thermal imaging images, thermal imaging videos, etc.), which is a technology that has been announced. The thermal image storage can receive and store the thermal image data from the thermal imaging camera, and the thermal image storage can transmit the thermal image data to the output device, etc.

[0057] The system can include a real image storage (e.g., SAC-NVR) that receives and stores real image data (videos, images, etc.) taken from the documentary camera. The real image storage can transmit the real image data to the output device, etc.

[0058] The server of the system can receive the thermal image data and the real image data, and include a more mapping storage in the thermal image data for storing mapping data.

[0059] The mapping storage can transmit the mapping data to the output device, etc.

[0060] The output device can play back by receiving and outputting the thermal image data and the real image data from the thermal image storage and the real image storage, respectively.

[0061] For example, the thermal image data and the real image data can include a shooting time, etc., respectively, and the system can include a client that inputs the shooting time, etc., and transmits to the thermal image storage and the real image storage.

[0062] When the thermal image data and the real image data receive the shooting time, etc., from the client, the thermal image data and the real image data can be transmitted to the client or the output device. That is, the system can have a search function.

[0063] As shown in Figure 1 and Figure 2 The system can be installed on one side of the electric vehicle charging station, including a spark sensor 3 that detects a spark and generates an induction signal when the spark occurs.

[0064] The spark sensor 3 example can be a spark sensor. The flame emits electromagnetic radiation in infrared, visible, and ultraviolet wavelengths depending on the fuel source, and the flame sensing sensor uses optical technology to perceive the flame. This is announced, and more specific descriptions will be omitted.

[0065] The detection signal can be transmitted to the client, etc., or to a notification device, etc., that receives the detection signal and generates a sound wave.

[0066] It is also possible to send to the notification 115 and the warning 116, etc.

[0067] Similarly, the present system can detect heat and flame simultaneously, including the flame sensor 3, thereby improving accuracy and reliability.

[0068] As will be described in more detail later, the present system can further improve accuracy and reliability, including smoke detection than 11e.

[0069] As shown in Figure 3 , the first sensor 11 can include the first measuring part 111 and the housing 113 in which the actual image camera 112 is installed, and the shielding part 114 which surrounds the upper part of the housing 113 and is placed in front of the housing 113.

[0070] Here, the front direction on the housing 113 represents the direction in which the first measuring part 111 is provided, and the left direction represents the left direction on the housing 113. Figure 4 , and the right direction represents the right direction on the housing 113 in the opposite direction. Figure 4 The same applies to the following description.

[0071] The first sensor 11 can include the notification part 115 (for example, including a speaker) provided on the upper part of the shielding part 114, which receives the alarm signal and outputs an alarm sound.

[0072] In addition, the first sensor 11 can include a warning light 116 (for example, including an LED) which emits light if the alarm signal is received, which is located in front of the housing 113.

[0073] The first sensor 11 can include a speaker device for outputting a voice signal transmitted from a microphone. The speaker device can be provided in front of the housing 113.

[0074] Although not shown, the present system installed on one side of the placement site can include a human body sensing sensor which generates a human body sensing signal by detecting a human body.

[0075] An example of a human body sensing sensor can be an infrared motion sensor (PIR) which can detect the movement of an infrared light source having a wavelength of 7 to 14 micrometers.

[0076] Since a human body emits infrared rays having a wavelength of 8 to 14 micrometers, it is an excellent sensor for detecting the movement of a human body. Since the PIR is announced, it is determined to omit more specific description. In addition, if the movement within the video is detected on the server storing the video, the movement can be detected, thereby causing an event.

[0077] The server 2 can include a human body corresponding part, receive a sensing signal from the comparison part, receive the human body sensing signal from the human body sensing sensor, generate a notification signal and send to the alarm part described later.

[0078] The system can include an alarm part (for example, including a speaker) that receives a notification signal from the human body corresponding part and generates a notification sound.

[0079] By this, it can be known whether there is a person in the electric vehicle charging station after the sensing signal occurs, and it can be used in the initial response.

[0080] As shown in Figure 3 The first sensing part 11 can include a mounting part 117 located behind the housing 113, an insertion slot formed recessed from the front to the rear of the mounting part 117, a nut hole formed from one side of the mounting part 117 to the insertion slot (to the insertion slot side), an extension slot 118 extending to the insertion slot from the rear of the housing 113, a main body inserted into the nut hole, and a main body 119a (119a recessed outside the insertion slot) signed with the nut hole 119a. The pressurizing part 119 can be included.

[0081] By inserting the nut hole into the pressurizing part 119 and fastening the screw, the extension part 118 can be pressed to the insertion slot side.

[0082] If the pressurizing part 119 does not pressurize the extension part 118, the degree of insertion of the extension part 118 into the insertion slot can be adjusted, and thus the position of the housing 113 can be adjusted.

[0083] By inserting a coin or the like insertion mechanism into the recess 119b, the main body 119a can be rotated.

[0084] As shown in Figure 3 and Figure 4 The first sensor 11 can include a smoke sensor 11e equipped in the case 113.

[0085] The working principle of the smoke sensor 11e is that, contrary to the device that emits light, the sensor that senses light in the opposite direction is located in the right angle direction, and the light emitted at ordinary times does not reach the sensor in the right angle direction, but smoke is generated, the light hits the tiny smoke particles, and is scattered in multiple directions, and the light is transmitted to the sensor.

[0086] The smoke sensor 11e is an example that uses the principle that if smoke is generated and diffused, the progress of infrared rays is hindered, and the light receiving amount of the water mineral part is reduced.

[0087] The smoke sensor 11e is also a product announced, and more specific description will be omitted.

[0088] The first sensor 11 may include a blower 11f mounted in front of the housing.

[0089] In addition, the first sensor 11 is mounted on the housing 113, and if the smoke sensor 11e detects smoke, it may include a control section (not shown) that drives the blower 11f.

[0090] The control unit (not shown) can be equipped with various control configurations or computing devices (e.g., computers, processors, and other electronic devices or modules), such as servers.

[0091] When the smoke sensing unit 11e detects smoke and sends a smoke sensing signal to the control unit, the control unit generates a drive signal to drive the blower 11f and sends it to the blower 11f.

[0092] In this way, the visibility of camera 112 can be ensured.

[0093] like Figure 4 As shown, the first sensing unit 11 can extend from the tube 11a at the lower part of the housing 113, the chimney hole formed on the side of the tube 11a, the side of the tube 11a outside, the nut 11b connected to the chimney hole, the vertical part 11c1 inserted into the tube 11a and the lower part of the vertical part (11c1) to the lower part, and is installed at the end in front of the conveyor 11f at the front 11c.

[0094] The first sensor 11 may include a bolt component 11d that is screwed into the vertical portion 11c1 of the pipe body 11a through the chimney hole and pressurized by a screw attached to the nut component 11b.

[0095] As described above, the present invention has been described with reference to specific matters (such as specific components) and limited embodiments and drawings, but this is only provided to help to have a more comprehensive understanding of the present invention. The present invention is not limited to the described embodiments, and various modifications and variations can be made from these descriptions by anyone with ordinary knowledge in the art to which the present invention pertains.

[0096] Therefore, the concept of the present invention should not be limited to the illustrated embodiments, but also includes all things that have equivalent or equivalent variations to the scope of the patent claims described below.
