Description

Technical Field

[0001] The present invention relates to the technical field of vehicle rat repelling, and in particular to a vehicle rat repelling method, device, electronic equipment and storage medium. Background Art

[0002] A car mouse repellent is a device designed to prevent mice from entering the engine compartment, the circuit system, and other key components of a car. With the electrification and intelligence of vehicles, the complex wiring and insulation materials (such as plastic, rubber, and plant-based materials) in the car are attractive to mice. Mice chewing on the wiring can not only cause car failures, but also pose safety hazards.

[0003] In the related art, ultrasound is often used to repel rats. The ultrasonic rat repellent emits high-frequency sound waves that rats cannot adapt to, thereby interfering with the nervous system of rats, making them feel uncomfortable and thus stay away from the vehicle.

[0004] However, the inventors found that the above methods mostly require manual activation and are not highly intelligent. Although the method is environmentally friendly and non-toxic, mice are easily adapted to the sound waves of this frequency band after long-term exposure, which greatly reduces the effect of mouse repelling. Summary of the invention

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] like Figure 1 The vehicle rat repelling method shown comprises the following steps:

[0038] S10: Acquire the vehicle's motion state. When the vehicle is in a moving state, the mouse repeller enters a dormant mode; when the vehicle is stationary, the mouse repeller enters a mouse repeller mode. In the embodiment of the present invention, by dynamically monitoring the vehicle's state, it is ensured that it only works under appropriate circumstances without manual activation, thereby improving the degree of intelligence. At the same time, it can also avoid the unnecessary impact of ultrasonic waves on humans or animals during vehicle operation, thereby improving safety and adaptability. Of course, it should also be pointed out here that there are many ways to acquire the vehicle's motion state. For example, the speed sensor equipped on the vehicle itself can be used, and the real-time speed of the vehicle can be directly acquired through the OBD interface or on vehicles that support the CAN bus protocol; it can also be achieved through visual detection by a GPS positioning module or a wheel speed sensor, a laser radar or a camera.

[0039] S20: Drive the ultrasonic generator to emit ultrasonic waves in a set mode. The frequency range of ultrasonic waves is 20-40kHz. 20-40kHz is the frequency that mice are most sensitive to. In order to avoid failure caused by the adaptation of mice due to long-term use of a single frequency for mouse repelling, mouse repelling is performed by changing multiple different frequencies, which can enhance the long-term repelling effect.

[0040] S30: Detecting the electric shock trigger signal, when the electric shock trigger signal is received, a DC voltage of a set magnitude is issued, and the DC voltage is used to drive away rats. In the embodiment of the present invention, the DC voltage used is set within a safe range to drive away rats, but it will not cause a serious safety threat to people. Of course, it should be pointed out here that in the embodiment of the present invention, the electric shock trigger signal can be set through a program, or the electric shock signal can be triggered by detecting whether a rat is approaching, for example, an infrared sensor or a microwave sensor can be used to determine whether a rat is approaching; specifically, an infrared sensor can be set in a part where rats are easy to invade, such as inside the engine compartment, around the chassis or near the wheel, and by detecting the change of infrared radiation in the environment, if a rapid change is detected, it indicates that a warm-blooded animal has entered the detection range; the microwave sensor is used to detect the reflection signal of a small moving target, and the reflection signal interval of the rat can be set by the frequency and intensity of the signal. When the received reflection signal falls into the interval, an electric shock is generated at the key part where the rat is easy to invade, so as to drive away the rats.

[0041] In the above embodiment, by first detecting the state of the vehicle, the mouse repelling mode is entered when the vehicle is in a stationary state, and no manual activation is required, thereby improving the intelligence of mouse repelling. Moreover, the present invention improves the continuous repelling ability of ultrasonic waves compared with the prior art by emitting ultrasonic waves of different frequencies. In addition, the present invention realizes the combination of long-distance and short-distance mouse repelling by combining ultrasonic waves with high-voltage electric shocks, thereby improving the effect of mouse repelling.

[0042] On the basis of the above embodiments, in the embodiments of the present invention, when obtaining the vehicle motion state, the three-axis acceleration of the vehicle is obtained, and whether the vehicle is in a stationary state is determined according to the set threshold. When performing the specific detection, the three-axis acceleration can be detected by the accelerometer sensor on the vehicle, and the three-axis combined acceleration is: where a x , a y , a z is the acceleration component in the three-axis direction, a total is the total acceleration at the current moment; when obtaining the acceleration component, the acceleration data can be low-pass filtered to remove the interference of high-frequency noise and short-term jitter in the sensor on the judgment; in the embodiment of the present invention, for the judgment of vehicle movement or stillness, the acceleration received by the vehicle when it is still is close to the acceleration of gravity, that is, 9.8m / s 2 If the total acceleration minus the gravity acceleration is less than a set threshold, such as 0.5, the vehicle is considered to be stationary.

[0043] In an embodiment of the present invention, when ultrasonic waves are emitted in a set mode, the frequencies of the ultrasonic waves include at least three frequencies: 22kHz, 28kHz and 37kHZ. Studies have shown that the frequency that mice are most sensitive to is 22kHz. In an embodiment of the present invention, higher frequency ultrasonic waves of 28kHz and 37kHz are applied on the basis of 22kHz to increase the repelling effect. In an embodiment of the present invention, the three ultrasonic sound emission modes can be emitted in a frequency segmented manner. Specifically, in an embodiment of the present invention, ultrasonic waves of a first frequency are emitted for a first set time period and then enter a sleep time of a second set time period, and then the first frequency ultrasonic waves are cycled N times, and then the above cycle is continued with the second frequency or the third frequency. In an exemplary ultrasonic frequency segmented sound emission mode of the present invention, Figure 3 and Figure 4 As shown in: first, a single-frequency intermittent wave is realized. After 20 milliseconds of ultrasonic wave generation, the system goes into deep sleep for 36 milliseconds, and keeps the frequency unchanged and runs in a cycle for 244 milliseconds; after the single-frequency intermittent ultrasonic wave is generated, the system goes into deep sleep for 4756 milliseconds, and then changes the sound frequency and runs the above process in a cycle.

[0044] In addition, in the embodiment of the present invention, the above three frequencies of ultrasound can be randomly emitted to further prevent the rodents from adapting. In addition, in the embodiment of the present invention, for rodents that have already contacted the vehicle, the device drives them away by outputting a high voltage.

[0045] In an embodiment of the present invention, a DC voltage is generated by a transformer through a PWM wave that is intermittently output, and at the same time, the AD collects the output voltage in real time and feeds back to the place where the PWM wave is generated to dynamically maintain the set voltage. Specifically, the main chip can be used to control the IO port to intermittently output PWM waves and generate a DC high voltage through a transformer. At the same time, the AD inside the main chip collects the output voltage in real time and feeds back to the place where the PWM wave is generated to dynamically maintain the mouse repellent device port to maintain a specific high voltage. Of course, it should be pointed out here that how to trigger the click signal has been described above, and the output position of the high voltage can be selected as the above-mentioned position where mice are easy to invade; in addition, in order to further improve safety, the electric shock function can be automatically turned off when the vehicle hood is opened, so as to further improve safety.
