[0114] Figure 1 is a block diagram illustrating a configuration of a mosquito repelling device according to an exemplary embodiment of the present invention.

[0115] refer to Figure 1 , the mosquito repellent device 100 may include a power device 110, a mosquito identification device 120, an illumination device 130, an ultrasonic sensor 140, a drive motor 150, and a controller 160. Each of the components 110 to 160 may include at least one processor. The at least one processor may be implemented as an application specific integrated circuit (ASIC), a central processing unit (CPU), a microcontroller, a microprocessor, and / or the like. Each of the components 110 to 160 may also include a non-transitory storage medium storing instructions executed by the at least one processor. The non-transitory storage medium may include a flash memory, a hard disk, a solid state disk (SSD), a random access memory (RAM), a static RAM (SRAM), a read-only memory (ROM), a programmable ROM (PROM), an electrically erasable programmable ROM (EEPROM), an erasable programmable ROM (EPROM), and / or the like.

[0116] The power device 110 may supply power required for the operation of the mosquito identification device 120, the illumination device 130, the ultrasonic sensor 140, the drive motor 150, and the controller 160. At this time, the power device 110 may supply power supplied from the outside, or may supply electric energy stored in a battery (not shown).

[0117] The power device 110 may include a function button (or function switch) 321 for generating power on and off commands. When a power-on command is received from the function button 321 (e.g., a power button), the power device 110 may start to supply power to the components 120 to 160 of the mosquito repellent device 100. When a power-off command is received from the function button 321, the power device 110 may stop supplying power to the components 120 to 160 of the mosquito repellent device 100.

[0118] The mosquito identification device 120 may identify the presence of mosquitoes in the vehicle using a mosquito identification algorithm stored in a memory (not shown). The mosquito identification algorithm may be derived through mosquito correlation analysis learned by artificial intelligence (AI).

[0119] The mosquito identification device 120 may measure the mosquito sound using a microphone (not shown). The mosquito identification device 120 may determine whether the frequency of the measured mosquito sound is within a predetermined reference frequency range (e.g., 250 Hz to 1 KHz or an average of 450 Hz ± tolerance). When it is determined that the frequency of the measured mosquito sound is within the predetermined reference frequency range, the mosquito identification device 120 may identify (or determine) that a mosquito is present.

[0120] The mosquito identification device 120 may determine the mosquito appearance stage based on the measured mosquito sound waveform. When the waveform of the mosquito sound is a single waveform, the mosquito identification device 120 may determine that the number of mosquitoes is one. When it is determined that the number of mosquitoes is one, the mosquito identification device 120 may determine the mosquito appearance stage as stage 1. When the waveform of the mosquito sound is an overlapping waveform, the mosquito identification device 120 may determine that the number of mosquitoes is two or more. When it is determined that the number of mosquitoes is two or more, the mosquito identification device 120 may determine the mosquito appearance stage as stage 2. The mosquito identification device 120 may determine the state in which no mosquito appears as a mosquito non-appearance stage (or stage 0).

[0121] When the power device 110 supplies power, the illumination device 130 may turn on the light source. A light emitting diode (LED), a lamp, and / or the like may be used as the light source. The illumination device 130 may turn on a light source of a predetermined color depending on a control command sent from the mosquito identification device 120. The illumination device 130 may change the light source color (or illumination color) depending on a control command sent from the mosquito identification device 120. Depending on an instruction of the mosquito identification device 120, the illumination device 130 may turn off a light source of a first color (e.g., yellow), and may turn on a light source of a second color (e.g., blue) or a third color (e.g., red).

[0122] For example, when the mosquito appearance stage is stage 0 (i.e., the mosquito does not appear stage), the mosquito identification device 120 may control the illumination device 130 to turn on the light source of the first color. In other words, the illumination device 130 may turn on the predetermined light source of the first color in the mosquito does not appear state. Thereafter, when it is determined that the mosquito appearance stage is stage 1, the mosquito identification device 120 may instruct the illumination device 130 to change the illumination color. Depending on the instruction of the mosquito identification device 120, the illumination device 130 may turn off the light source of the first color and may turn on the light source of the second color.

[0123] As another example, when the mosquito appearance stage changes from the mosquito non-appearance stage to stage 2, the mosquito identification device 120 may send a lighting color change command to the lighting device 130. Depending on the received lighting color change command, the lighting device 130 may turn off the light source of the first color and turn on the light source of the third color.

[0124] As another example, when the mosquito appearance stage changes from stage 1 or 2 to the mosquito non-appearance stage, the mosquito identification device 120 may send a lighting color change command to the lighting device 130. Depending on the received lighting color change command, the lighting device 130 may turn off the light source of the second color or the third color, and may turn on the light source of the first color.

[0125] In addition, the illumination device 130 may adjust the illumination radiation angle (or radiation direction) under the control of the mosquito identification device 120. At this time, the mosquito identification device 120 may identify the ultrasonic radiation position by communicating with the controller 160, and may adjust the radiation angle of the light source based on the identified ultrasonic radiation position. The illumination device 130 may radiate light to the ultrasonic radiation position or the mosquito appearance position by using a laser or the like as a light source.

[0126] The illumination device 130 and the mosquito identification device 120 may be arranged together on one printed circuit board (PCB).

[0127] The ultrasonic sensor 140 may generate an ultrasonic signal or receive an ultrasonic signal from the outside. The ultrasonic sensor 140 may include an ultrasonic transducer (or ultrasonic vibrator) and an ultrasonic speaker. The ultrasonic sensor 140 may have specifications such as those shown in Table 1 below.

[0128] [Table 1]

[0129]

[0130] The ultrasonic sensor 140 may generate an ultrasonic signal having a frequency and / or a waveform determined by the controller 160. The ultrasonic sensor 140 may adjust an output voltage and / or sensitivity of the ultrasonic signal according to a control command transmitted from the controller 160.

[0131] At least two or more ultrasonic sensors 140 may be mounted on the mosquito repelling device 100. The ultrasonic sensor 140 may be implemented as piezoelectric ceramics, piezoelectric elements, and / or the like.

[0132] The driving motor 150 may rotate the ultrasonic sensor 140 based on the radiation pattern determined by the controller 160. For example, the driving motor 150 may rotate the ultrasonic sensor 140 180 degrees in a first direction (or forward direction), and may rotate the ultrasonic sensor 140 180 degrees in a second direction (or reverse direction) opposite to the first direction. At this time, the driving motor 150 may repeat the rotation of 180 degrees in the first direction and repeat the rotation of 180 degrees in the second direction. The driving motor 150 may be implemented as a direct current (DC) motor.

[0133] The controller 160 may control the overall operation of the mosquito repelling device 100. The controller 160 may include a DC converter.

[0134] The controller 160 may identify mosquitoes in the vehicle using the mosquito identification device 120. When the mosquito is identified to be present, the controller 160 may determine the mosquito appearance stage using the mosquito identification device 120. When the mosquito appearance stage is determined, the mosquito identification device 120 may transmit information about the determined mosquito appearance stage to the controller 160.

[0135] When a mosquito is identified to be present in the vehicle, the controller 160 may control the driving motor 150 to rotate the ultrasonic sensor 140. In other words, the controller 160 may implement a hemispherical sound field by the rotation of the ultrasonic sensor 140. At this time, the ultrasonic sensor 140 may generate an ultrasonic signal having a predetermined frequency (e.g., 30 KHz). The controller 160 may variably control the frequency and / or radiation pattern of the ultrasonic signal.

[0136] The controller 160 may actively control the ultrasonic power based on the mosquito appearance stage depending on the active ultrasonic control (AUC) logic. The controller 160 may determine the output voltage and / or sensitivity (or sound pressure output) of the ultrasonic sensor 140 based on the mosquito appearance stage.

[0137] The controller 160 may control the driving of the ultrasonic sensor 140 based on the mosquito appearance stage. When the mosquito appearance stage is stage 1, the controller 160 may determine the ultrasonic control scheme as ultrasonic low-power radiation. When the ultrasonic control scheme is determined to be ultrasonic low-power radiation, the controller 160 may adjust the output voltage of the ultrasonic sensor 140 within the range of 5V to 12V, and may adjust the sensitivity of the ultrasonic sensor 140 to 112dB or less.

[0138] When the mosquito appearance stage is stage 2, the controller 160 may determine the ultrasonic control scheme as ultrasonic high-power radiation. When the ultrasonic control scheme is determined to be ultrasonic high-power radiation, the controller 160 may adjust the output voltage of the ultrasonic sensor 140 within the range of 20V to 36V, and may adjust the sensitivity of the ultrasonic sensor 140 to 117dB or more.

[0139] The controller 160 may play a mosquito repelling sound source corresponding to the mosquito appearance stage, and may output the played sound source to the outside through the ultrasonic speaker of the ultrasonic sensor 140 .

[0140] Furthermore, when the ultrasonic wave signal is radiated, the controller 160 may control the lighting device 130 to illuminate the ultrasonic wave radiated position and / or the mosquito position using a light source such as a laser.

[0141] The controller 160 may identify whether the mosquitoes are repelled using the mosquito identification device 120. When the mosquito identification device 120 does not detect the mosquito sound within a predetermined time (e.g., 30 seconds), the controller 160 may determine that the mosquito repelling is completed. When the mosquito identification device 120 detects the mosquito sound within a predetermined time, the controller 160 may determine that the mosquito repelling is not completed.

[0142] Figure 2 The icon will Figure 1 A diagram showing an example of a mosquito repellent device being applied to a vehicle environment. Figure 3 yes Figure 1 An exploded perspective view of the mosquito repellent device shown. Figure 4 yes Figure 1 A combined stereogram of the mosquito repellent device shown.

[0143] The mosquito repellent device 100 can be made portable. Figure 2 As shown, the mosquito repellent device 100 may be accommodated in a cup holder 210 in a vehicle, or may be mounted on a handle hanger 220. Figure 2 In addition to the position shown, the mosquito repellent device 100 can be installed (or arranged) at another position in the vehicle.

[0144] The mosquito repelling device 100 may be composed of a first body 310, a second body 320, and a third body 330. A belt 311 may be installed on an upper portion of the first body 310.

[0145] The mosquito identification device 120, the lighting device 130, the driving motor 150, and the controller 160 may be arranged in a space formed at the inner side of the second body 320. The mosquito identification device 120 and the lighting device 130 may be arranged on one PCB.

[0146] In addition, the function button 321 may be provided at one point outside the second body 320. The function button 321 may be implemented in the form of a button switch or the like.

[0147] The inner cover 331 may be disposed at the inner side of the third body 330 .

[0148] The sensor mounting part 332 on which at least two ultrasonic sensors 140 are mounted may be disposed in a space formed at the inner side of the inner cover 331 of the third body 330 .

[0149] An ultrasonic sensor 140 may be mounted on the first surface (or upper surface) of the sensor mounting member 332. An embedded microphone for detecting the presence of mosquitoes and the ultrasonic sensor 140 may be mounted on the first surface.

[0150] At least two ultrasonic sensors 140 may be mounted on the second surface (or inclined surface) of the sensor mounting member 332. The second surface may be composed of two pairs of two inclined surfaces opposite to each other. The inclinations (or angles) of the inclined surfaces opposite to each other may be the same as each other, and the inclinations of the inclined surfaces not opposite to each other may be different from each other.

[0151] At least two ultrasonic sensors 140 may be mounted on the second surface to have at least two radiation angles. For example, when the ultrasonic sensors 140 are mounted on four inclined surfaces of the sensor mounting member 332, respectively, the first ultrasonic sensor and the third ultrasonic sensor arranged opposite to each other may be mounted to have a radiation angle of 45 degrees, and the second ultrasonic sensor and the fourth ultrasonic sensor arranged diagonally to the first ultrasonic sensor and the third ultrasonic sensor and opposite to each other may be mounted to have a radiation angle of 10 degrees.

[0152] The driving motor 150 may rotate the sensor mounting member 332 relative to the longitudinal axis A of the mosquito repelling device 100 . In other words, the driving motor 150 may rotate the ultrasonic sensor 140 through the rotation of the sensor mounting member 332 .

[0153] Figure 5 It is illustrated by Figure 1 A diagram showing an example of a mosquito repellent device implementing a hemispherical sound field.

[0154] refer to Figure 5 , the radiation angles of the ultrasonic sensors mounted on the upper surface and the inclined surface of the sensor mounting part 332 can be allocated in the upper direction UPR, the middle direction MID, and the lower direction LWR, and the ultrasonic sensors can be installed. For example, the ultrasonic sensor mounted on the upper surface of the sensor mounting part 332 can be installed to face the 90-degree direction, and the ultrasonic sensor mounted on the inclined surface can be installed to face the 45-degree direction and the 10-degree direction. In this way, since the radiation angles of the ultrasonic sensors can be allocated differently and the ultrasonic sensors can be installed, a hemispherical sound field 400 with an expanded mosquito repellent effectiveness radius (e.g., 3m) can be implemented.

[0155] Figure 6 is a flow chart illustrating a method for operating a mosquito repelling device according to an exemplary embodiment of the present invention.

[0156] In S100, the mosquito repellent device 100 may identify the presence of mosquitoes in the vehicle through the mosquito identification device 120. The mosquito identification device 120 may use a microphone to measure mosquito sounds. The mosquito identification device 120 may determine whether the frequency of the measured mosquito sound is within a predetermined reference frequency range (e.g., 250 Hz to 1 KHz). When it is determined that the frequency of the measured mosquito sound is within the predetermined reference frequency range, the mosquito identification device 120 may identify the presence of mosquitoes.

[0157] In S110, the mosquito repellent device 100 may determine the mosquito appearance stage through the mosquito identification device 120. The mosquito identification device 120 may determine the mosquito appearance stage based on the waveform of the measured mosquito sound. When the waveform of the mosquito sound is a single waveform, the mosquito identification device 120 may determine the mosquito appearance stage as stage 1. When the waveform of the mosquito sound is an overlapping waveform, the mosquito identification device 120 may determine the mosquito appearance stage as stage 2.

[0158] In S120, the mosquito repellent device 100 may control the illumination color based on the determined mosquito appearance stage. As an example, when the mosquito appearance stage is the mosquito non-appearance stage, the mosquito identification device 120 may control the illumination device 130 to turn on the light source of the first color. Thereafter, when it is determined that the mosquito appearance stage is stage 1, the mosquito identification device 120 may instruct the illumination device 130 to change the illumination color. Based on the instruction of the mosquito identification device 120, the illumination device 130 may turn off the light source of the first color and turn on the light source of the second color.

[0159] As another example, when the mosquito appearance stage changes from the mosquito non-appearance stage to stage 2, the mosquito identification device 120 may send a lighting color change command to the lighting device 130. Depending on the received lighting color change command, the lighting device 130 may turn off the light source of the first color and turn on the light source of the third color.

[0160] As another example, when the mosquito appearance stage changes from stage 1 or 2 to the mosquito non-appearance stage, the mosquito identification device 120 may send a lighting color change command to the lighting device 130. Depending on the received lighting color change command, the lighting device 130 may turn off the light source of the second color or the third color, and may turn on the light source of the first color.

[0161] In S130, the mosquito repellent device 100 may adjust the ultrasonic power and / or sensitivity based on the determined mosquito appearance stage. When the mosquito identification device 120 determines the mosquito appearance stage, the mosquito repellent device 100 may start to radiate ultrasonic signals using the ultrasonic transducer of the ultrasonic sensor 140. The mosquito repellent device 100 may control the driving motor 150 so that the sensor mounting part 332 on which the ultrasonic sensor 140 is mounted repeats 180 degrees of forward rotation and 180 degrees of reverse rotation.

[0162] In addition, the controller 160 of the mosquito repellent device 100 may control the driving of the ultrasonic sensor 140 based on the mosquito appearance stage. When it is identified that the mosquito appearance stage is stage 1, the controller 160 may determine the ultrasonic control scheme as ultrasonic low-power radiation. When the ultrasonic control scheme is determined to be ultrasonic low-power radiation, the controller 160 may adjust the output voltage of the ultrasonic sensor 140 within the range of 5V to 12V, and may adjust the sensitivity of the ultrasonic sensor 140 to 112dB or less.

[0163] When it is identified that the mosquito appearance stage is stage 2, the controller 160 may determine the ultrasonic control scheme as ultrasonic high-power radiation. When the ultrasonic control scheme is determined to be ultrasonic high-power radiation, the controller 160 may adjust the output voltage of the ultrasonic sensor 140 within the range of 20V to 36V, and may adjust the sensitivity of the ultrasonic sensor 140 to 117dB or more.

[0164] In S140, the mosquito repellent device 100 may play a mosquito repellent sound source based on the determined mosquito appearance stage. The controller 160 of the mosquito repellent device 100 may access a mosquito repellent sound source corresponding to the mosquito appearance stage from the memory, and may play the accessed mosquito repellent sound source. The controller 160 may output the played mosquito repellent sound source to the outside through a speaker.

[0165] In S150, the mosquito repellent device 100 may radiate light to the ultrasonic radiation position. The illumination device 130 may control the illumination radiation angle (or radiation direction) depending on the control command of the controller 160 received through the mosquito identification device 120. At this time, the mosquito identification device 120 may identify the ultrasonic radiation position by communicating with the controller 160, and may adjust the radiation angle of the light source based on the identified ultrasonic radiation position.

[0166] In S160, the mosquito repellent device 100 may determine whether the mosquitoes in the vehicle are repelled using the mosquito identification device 120. When the mosquito identification device 120 does not detect the mosquito sound within a predetermined time (e.g., 30 seconds), the controller 160 of the mosquito repellent device 100 may determine that the mosquito repellent is completed. When the mosquito identification device 120 detects the mosquito sound within the predetermined time, the controller 160 may determine that the mosquito repellent is not completed.

[0167] When it is determined that the mosquito is repelled, the mosquito repelling device 100 may stop the mosquito repelling function. When it is determined that the mosquito is not repelled, the mosquito repelling device 100 may maintain the mosquito repelling function and may perform S160 again whenever a predetermined time elapses.

In other words, the mosquito repelling device 100 can variably control the target frequency between 25KHz and 35KHz according to mosquito characteristics according to regions, thereby maximizing mosquito repelling performance.

[0171] The mosquito repellent device 100 may variably control the ultrasonic power and / or sensitivity based on the mosquito appearance stage. The mosquito repellent device 100 may detect the sound of the mosquito using a microphone embedded therein. The mosquito repellent device 100 may classify the mosquito appearance stage into stage 1 or stage 2 using a sound analysis algorithm. When the mosquito appearance stage is stage 1, that is, when about one mosquito is detected, the mosquito repellent device 100 may set the target frequency to 30KHz, the output voltage of the ultrasonic wave may be set to 5V to 12V, and the sensitivity may be set to 112dB or less. When the mosquito appearance stage is stage 2, that is, when two or more mosquitoes are detected, the mosquito repellent device 100 may set the target frequency to 30KHz, the output voltage of the ultrasonic wave may be set to 20V to 36V, and the sensitivity may be set to 117dB or more. The mosquito repellent device 100 may actively control the operation of the ultrasonic sensor 140 based on the set target frequency, output voltage (or ultrasonic power) and sensitivity (or ultrasonic sensitivity).

The mosquito repellent device 100 may use a camera, a navigation terminal, and / or the like to determine whether the vehicle is in a car camping state and whether the user in the vehicle is lying down.

[0176] When the vehicle environment is in a driving state or when the user lies in a car camping environment, in S230, the mosquito repellent device 100 may use a sensor to identify the temperature, humidity, lighting intensity, and / or the like in the vehicle. The mosquito repellent device 100 may identify whether the temperature in the vehicle is a high temperature of 20° C. or higher. The mosquito repellent device 100 may identify whether the relative humidity in the vehicle is a high humidity of 30% or higher. When the lighting intensity is less than or equal to the reference lighting intensity, the mosquito repellent device 100 may identify whether it is dark in the vehicle.

[0177] In S240, the mosquito repellent device 100 may identify the mosquito appearance stage through the mosquito identification device 120. The mosquito identification device 120 may use a microphone to measure the mosquito sound. The mosquito identification device 120 may analyze the waveform of the measured mosquito sound to estimate the number of mosquitoes. The mosquito identification device 120 may determine the mosquito appearance stage based on the estimated number of mosquitoes. In detail, when the number of mosquitoes is estimated to be 1, the mosquito identification device 120 may determine the mosquito appearance stage as stage 1. When the number of mosquitoes is estimated to be two or more, the mosquito identification device 120 may determine the mosquito appearance stage as stage 2.

[0178] In S250, the mosquito repellent device 100 may adjust the ultrasonic power and / or sensitivity based on the mosquito appearance stage, and may control the air conditioning device based on the temperature, humidity, lighting intensity and / or the like. The mosquito repellent device 100 may determine the ultrasonic power and / or sensitivity based on the mosquito appearance stage. The mosquito repellent device 100 may operate the ultrasonic sensor 140 based on the determined ultrasonic power and / or sensitivity to radiate ultrasonic waves. When the temperature is greater than or equal to 25°C, the mosquito repellent device 100 may radiate ultrasonic signals, and may operate the air conditioning function of the air conditioning device to reduce the temperature to 20°C or lower. In addition, when the relative humidity is greater than or equal to 30%, the mosquito repellent device 100 may operate the air conditioning device to reduce the relative humidity to 30% or lower. The mosquito repellent device 100 may send and receive data (e.g., control commands) with the air conditioning device using wired or wireless communication.

[0179] In S260 , when the vehicle environment is not in a driving state and the user is not lying in the car camping environment, the mosquito repelling device 100 may recognize the vehicle environment as a stopped state.

The vehicle 500 may use a camera and / or the like to identify the location where the mosquito repelling device 510 is installed.

[0211] In S340, the vehicle 500 may visualize the sound pressure output information in the mosquito repellent sound field. The mosquito repellent device 510 may radiate ultrasonic signals.

As another example, when the mosquito repellent device 510 is installed on a handle hanger, the vehicle 500 may determine whether there is an area where the mosquito repellent treatment is limited. As another example, the vehicle 500 may determine whether there is a mosquito repellent restricted area due to power limitation of the ultrasonic sensor 511. In other words, when the ultrasonic sensor 511 of the mosquito repellent device 510 transmits an ultrasonic signal at maximum power, the vehicle 500 may extract a mosquito repellent weak area in which the sound pressure of the ultrasonic signal received by the sound pressure sensor installed for each position in the vehicle 500 is less than the reference sound pressure.

The vehicle 500 may determine the optimal installation position of the mosquito repelling device 510 based on the position of mosquitoes, the seat position of passengers, and / or luggage information.

[0221] Furthermore, according to the installation position of the mosquito repellent device 510 and / or the radiation angle of the ultrasonic signal, the vehicle 500 may additionally consider the reflection angle on the reflector (e.g., door glass) to determine the optimal installation position of the mosquito repellent device 510. In other words, the vehicle 500 may consider the coverage of the reflector in the vehicle 500 according to the installation position of the mosquito repellent device 510 to determine the optimal installation position of the mosquito repellent device 510. The reflector in the vehicle 500 may include a front windshield, a side door glass, a rear glass, and / or the like.

For example, when it is determined that multiple reflections of the door glass at the driver's seat and the passenger seat at the position where the mosquito repellent device 510 is currently installed can cover the mosquito repellent restricted area, the vehicle 500 may determine the center console cup holder that can cover the front of the vehicle 500 and cover the mosquito repellent restricted area using multiple reflections from the door glass at the driver's seat and the passenger seat as the best installation position.

[0223] When it is determined that there is no mosquito repellent restricted area, in S460, the vehicle 500 may monitor the sound pressure level within the sound pressure effectiveness radius of the mosquito repellent device 510. The sound field effectiveness radius may refer to a predetermined radius relative to the installation location of the mosquito repellent device 510. The vehicle 500 may visualize and output the monitored sound pressure level on the display of the navigator 501. When monitoring the sound pressure level in the sound field effectiveness radius, the vehicle 500 may monitor the sound pressure level regarding multiple reflections from reflectors in the vehicle 500.
