[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0040] Millimeter Wave Radar: Millimeter wave radar transmits and receives millimeter wave signals, and uses parameters such as the time difference or phase difference between the reflected wave and the transmitted wave to calculate the distance, speed, angle and other information of the target object. Its working principle is mainly based on the propagation and reflection principle of electromagnetic waves. It has a certain penetrating ability and can penetrate obstacles such as fog, smoke, and dust to achieve all-weather detection and tracking.

[0041] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0042] First, please refer to Figure 1 , Figure 1 This is a flow chart of a method for driving away target animals according to an embodiment of the present application. The method for driving away target animals provided in this embodiment includes the following steps:

[0043] Step S1: Continuously detect the surroundings of the vehicle.

[0044] Step S2: When a target animal appears, the first dispersing sound wave corresponding to the target animal is matched in a preset animal-repelling sound wave database and emitted.

[0045] Step S3: Determine whether the expulsion fails. If yes, proceed to step S4; if no, return to step S1.

[0046] It should be noted that the condition for failure of expulsion here is that after a preset time, the target animal is still within a preset range around the vehicle. The preset time and preset range can be adjusted according to the environment and vehicle model of the vehicle.

[0047] Step S4: matching the animal with the highest similarity to the target animal in a preset animal-driving sound wave database, and obtaining a second driving sound wave corresponding to the animal.

[0048] Step S5: adjusting the frequency spectrum of the first driving sound wave according to the second driving sound wave, and emitting the adjusted first driving sound wave.

[0049] Step S6: Determine whether the expulsion fails. If yes, proceed to step S7; if no, proceed to step S8.

[0050] It should be noted that the conditions for failure of expulsion here are the same as those in step S3.

[0051] Step S7: Alarm.

[0052] Step S8: updating the first driving sound wave in the preset animal-driving sound wave database to the adjusted first driving sound wave, and then returning to step S1.

[0053] It should be noted that the first and second repelling sound waves are specifically the sounds made by the natural enemies of animals (for example, if the target animal is a rodent, the repelling sound wave includes the sound of a cat), and ultrasonic or infrasonic waves of the sensitive areas of animals. Compared with chemical means such as mothballs, emitting sound waves will not cause any harm to wild animals, and can protect wild animals while repelling them.

[0054] The method drives away the target animal by emitting sound waves. When the first drive fails, the drive sound wave corresponding to the animal with the highest similarity to the target animal is obtained from the animal-drive sound wave database, and the frequency spectrum of the drive sound wave corresponding to the target animal is adjusted based on the drive sound wave. If the drive is successful after adjustment, the adjusted drive sound wave is stored in the animal-drive sound wave database to ensure the continuous iteration of data in the database, thereby effectively driving away wild animals in the long term. If the drive fails after adjustment, an alarm is sounded to remind that a wild animal has invaded the vehicle, so that the owner can respond quickly and drive away the target animal to ensure the safety of the vehicle.

[0055] In some embodiments, the method for driving away target animals further comprises the following steps:

[0056] According to the location of the vehicle and the preset area division table, the area where the vehicle is located is determined, and the preset animal-driving sound wave database corresponding to the area is obtained. The animal-driving sound wave database includes the name of the animal, the identity feature information of the animal, and the driving sound wave corresponding to the animal.

[0057] It should be noted that the animal's identity characteristic information should use information that has obvious individual recognition and can be collected through vehicle-mounted equipment, such as the animal's body shape, voice, facial image, walking posture and other information.

[0058] In addition, obtaining the animal-driving sound wave database corresponding to the area where the vehicle is located, rather than all animal-driving sound wave databases, can effectively reduce the system response time. And because the habits of the same wild animals living in different regions are different, different driving sound waves can be stored for the same wild animals in databases in different regions, thereby improving the pertinence and effectiveness of the driving sound waves.

[0059] In some embodiments, in the above step S1, continuously detecting the surroundings of the vehicle includes the following steps:

[0060] First, with the vehicle as the center, the on-board millimeter-wave radar continuously scans within the first preset range.

[0061] When a living being is scanned, the identity feature information of the living being is obtained through the vehicle-mounted millimeter-wave radar and the vehicle-mounted infrared camera.

[0062] Finally, the identity feature information of the creature is compared with the identity feature information of each entry in the preset animal-repelling sound wave database in turn. When the similarity between the two is greater than or equal to the preset first similarity threshold, it is determined that the target animal appears around the vehicle.

[0063] It should be noted that, in this embodiment, the identity feature information at least includes the body shape information, gait information and facial information of the organism. The millimeter wave radar can penetrate some obstacles (such as fog, haze, etc.) to obtain the body shape information of the organism, and obtain its gait information based on the movement trajectory of the organism. The infrared camera can clearly image at night or in low light conditions and obtain an infrared image of the organism's face. Combining the advantages of the two greatly improves the accuracy and reliability of the identity feature information obtained.

[0064] In some embodiments, the above-mentioned steps of obtaining the identity feature information of the creature by using the vehicle-mounted millimeter wave radar are as follows:

[0065] First, a dot matrix image of the organism is obtained through the vehicle-mounted millimeter-wave radar, and the corresponding body shape information of the organism is generated according to the dot matrix image of the organism.

[0066] Afterwards, the characteristic motion points of the creature are acquired through the vehicle-mounted millimeter-wave radar, and the corresponding gait information of the creature is generated according to the characteristic motion points of the creature.

[0067] Specifically, the vehicle-mounted millimeter-wave radar emits high-frequency millimeter-wave signals around the vehicle. When the millimeter-wave signal encounters the creature, part of the signal will be reflected back. The millimeter-wave radar processes the received reflected signal and calculates the distance and angle of the reflection point relative to the radar by measuring parameters such as the round-trip time or phase difference of the information. All reflection points are located in three-dimensional space according to the distance and angle information to generate a dot matrix of the creature. The dot matrix is ​​then further processed, such as filtering and denoising, and all reflection points are connected through a preset algorithm to form the outline of the creature, thereby generating the body shape information of the creature.

[0068] After obtaining multiple dot matrix images, the motion trajectory of each reflection point in the dot matrix image can be tracked through a preset algorithm to identify points with significant motion characteristics. These points usually represent the motion trends of key parts of the organism (such as limbs, head, etc.). Then, the motion trajectory of all identified characteristic motion points is analyzed, and their motion parameters such as speed and acceleration are calculated to generate the gait information of the organism. The gait information includes information such as step frequency and step length that can describe the movement mode and rhythm of the organism.

[0069] It should be noted that the characteristic movement points of the creature can also be obtained through the vehicle-mounted ultrasonic radar.

[0070] In some embodiments, the above-mentioned steps of obtaining the identity information of the creature through the vehicle-mounted infrared camera are as follows:

[0071] The imaging map of the infrared image of the creature is obtained through the vehicle-mounted infrared camera, and the facial information corresponding to the creature is generated according to the imaging map of the infrared image of the creature.

[0072] In some embodiments, the above-mentioned channel for obtaining the biometric identity feature information also includes:

[0073] The sound spectrum of the organism is obtained through the vehicle-mounted microphone, and the voiceprint information corresponding to the organism is generated according to the sound spectrum of the organism.

[0074] It should be noted that the sampling frequency of the vehicle microphone can be increased or decreased according to specific environmental conditions to filter out unnecessary environmental noise and obtain more accurate voiceprint information.

[0075] In some embodiments, in the above step S4, the animal with the highest similarity to the target animal is matched in a preset animal-repelling sound wave database to obtain a second repelling sound wave corresponding to the animal, and the specific steps are as follows:

[0076] The identity information of the target animal is compared with the identity feature information of each entry in the above-mentioned preset animal-driving sound wave database in turn, the similarity between the two is calculated, and the driving sound wave corresponding to the entry with the highest similarity is used as the second driving sound wave.

[0077] It should be noted that the animal with the highest similarity to the target animal does not include the target animal.

[0078] In some embodiments, in the above step S7, the alarm step is as follows:

[0079] The identity characteristic information of the target animal and the location of the target animal are sent to the user's mobile phone application.

[0080] In some embodiments, when the vehicle is started, the above method of driving away the target animal is interrupted.

[0081] It should be noted that the method is interrupted when the vehicle is started in order to prevent the pets carried by the owner or other persons in the vehicle from accidentally triggering the method, causing the vehicle to continuously emit repelling sound waves and causing the pets in the vehicle to become restless.

[0082] Second, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a device for driving away target animals according to an embodiment of the present application. The device for driving away target animals provided in this embodiment includes the following modules:

[0083] The transmitting module is used to match and transmit the first driving sound wave corresponding to the target animal in the preset animal-driving sound wave database when the target animal appears, and is also used to transmit the adjusted first driving sound wave.

[0084] The adjustment module is used to match the animal with the highest similarity to the target animal in a preset animal-driving sound wave database when the driving fails, and obtain a second driving sound wave corresponding to the animal.

[0085] It is also used to adjust the frequency spectrum of the first driving sound wave according to the second driving sound wave, and then update the first driving sound wave in the preset animal-driving sound wave database to the adjusted first driving sound wave.

[0086] The alarm module is used to alarm after the adjusted first driving sound wave fails.

[0087] The device detects whether there is a target animal around the vehicle through a detection module. When there is a target animal, the transmission module is used to transmit the driving sound wave corresponding to the target animal to drive it away. When the first driving fails, the adjustment module is used to match the animal with the highest similarity to the target animal in the animal-driving sound wave database, and the driving sound wave of the target animal is adjusted according to the sound wave corresponding to the animal, and then the driving is performed again. If the driving is successful, the adjustment module is used to update the driving sound wave corresponding to the target animal in the animal-driving sound wave database. If the driving fails, an alarm is issued through the alarm module.

[0088] Since wild animals will learn and adapt after being driven away many times, the effect of using fixed driving sound waves will gradually weaken until it disappears. This device saves the effective driving sound waves for the target animals through the adjustment module, ensuring the continuous iteration of data in the animal-driving sound wave database, thereby effectively driving away wild animals in the long term.

[0089] In some embodiments, the device for driving away target animals further includes the following modules:

[0090] The synchronization module uploads the identity feature information of the target animal and the adjusted first driving sound wave to a preset server, and sends them to all vehicles equipped with the device within a range of a first distance with the current position of the vehicle as the center.

[0091] In this embodiment, the first distance is preferably set to 1 kilometer.

[0092] It should be noted that by uploading the adjusted driving sound waves to the preset server and synchronizing them to other nearby vehicles, the iteration efficiency of the animal-driving sound wave database can be effectively accelerated, thereby achieving the effect of point-to-surface, multi-point learning and multiple iterations, thereby improving the practicality of the device.
