Description

Technical Field

[0001] The present invention relates to the technical field of automatic bird-repelling, and in particular to a security device and method for automatic bird-repelling. Background Art

[0002] In the field of security, especially when it comes to the protection of important infrastructure and high-risk areas, bird activities have become an issue that cannot be ignored. Existing bird-repelling methods and technologies mainly include physical methods, chemical methods and electronic methods. Physical methods such as installing bird-proof nets and bird-repelling wind wheels, although simple and easy, have limited effects in complex environments and high maintenance costs; chemical methods such as spraying bird repellents, although effective in the short term, may cause harm to the environment and human health in the long term; electronic methods such as sound and light bird repellents, ultrasonic bird repellents, etc., have gradually become the mainstream bird repellent methods due to their harmless and efficient characteristics. However, existing electronic bird repellent equipment still has problems such as limited coverage, low intelligence, inconvenient installation and maintenance, and high energy consumption.

[0003] For example, in security monitoring systems, the stability and accuracy of the camera are crucial. However, birds moving around the camera may cause the camera angle to deviate, affecting the monitoring effect. Traditional physical and chemical methods are not effective around cameras and may cause damage to the camera itself. To solve these problems, micro bird repellent devices can be installed on existing cameras later. This device is small in size and easy to install. It does not affect the appearance and stability of the camera. By integrating non-lethal bird repellent technologies such as sound, light, ultrasound or laser, it can effectively repel birds and prevent them from staying around the camera, thereby avoiding the situation where the camera angle is offset and ensuring the normal operation of the monitoring system.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1

[0033] Reference Figure 1-Figure 3 , which is the first embodiment of the present invention, provides an automated bird-repelling security device, including a three-axis steering component 100 and a bird-repelling component 200 detachably mounted on the three-axis steering component 100, the three-axis steering component 100 includes a base 101 for mounting and a three-axis rotating arm 102 arranged on the base 101, a mounting piece 103 is arranged at the end of the three-axis rotating arm 102, the bird-repelling component 200 includes a shell 201 located inside the mounting piece 103, a Doppler radar 202, a processor and an actuator 203 installed inside the shell 201, the Doppler radar 202 is used to detect the position of the bird, the processor is used to receive the bird position information scanned by the Doppler radar 202, and drive the actuator 203 to repel the bird according to the position information, and is also used to control the three-axis rotating arm 102 to rotate in all directions.

[0034] In this embodiment, the present invention avoids real-time monitoring by setting a processor to control the three-axis rotating arm 102 (all-round scanning without blind spots to ensure the comprehensiveness of the scanning range) to rotate every ten minutes, thereby significantly reducing energy consumption. Specifically, the design of the three-axis rotating arm 102 allows the device to move freely in three dimensions: horizontal, vertical, and rotation, ensuring the comprehensiveness and no blind spots of the scanning range. This periodic scanning mechanism can not only effectively detect the activities of birds, but also enter a low-power mode during non-scanning periods, thereby significantly saving electricity.

[0035] During each scanning process, the processor controls the Doppler radar 202 to scan synchronously to detect the position of the bird. The Doppler radar 202 uses the Doppler effect to determine the speed and position of the target by the frequency difference between the transmitted and received signals, and has high sensitivity and high precision. When the Doppler radar 202 detects that the bird is within the range that needs to be driven away, the processor will immediately control the three-axis rotating arm 102 to stop rotating and keep the current position unchanged so that the actuator 203 can perform the bird-repelling operation. This precise detection and positioning mechanism ensures the efficiency and accuracy of the bird-repelling operation.

[0036] Once the bird is detected to be within the range to be driven away, the processor will control the actuator 203 to perform the bird-repelling operation. The actuator 203 may include a variety of bird-repelling means such as a player, an ultrasonic generator, and a laser generator. The player can play the sound of the natural enemy of the bird or the wailing sound of the bird when it is attacked, the ultrasonic generator can emit ultrasonic waves of a specific frequency, and the laser generator can emit a green laser beam. These means can be used alone or in combination, and the most effective bird-repelling method can be selected according to the actual situation. The whole process is fully automated, without manual intervention, which greatly improves the efficiency of bird-repelling.

[0037] The overall volume of the present invention is small, which is convenient for later installation. The compact design of the device makes it suitable for installation and use in a variety of environments, such as airports, substations, farmlands, etc. In addition, the device has an external jack for later expansion. Users can add more sensors or actuators 203 according to actual needs to enhance the function and performance of the device. This modular design not only improves the flexibility of the device, but also extends the service life of the device.

[0038] In order to ensure the high reliability and stability of the device, the present invention adopts a variety of designs and technologies. First, the combined design of the three-axis rotating arm 102 and the Doppler radar 202 ensures the comprehensiveness and accuracy of the scan. Secondly, the intelligent control algorithm of the processor can effectively manage and coordinate the work of each component to ensure the stable operation of the device in various environments. In addition, the waterproof and dustproof design and the sturdy fixed structure of the device enable it to work for a long time in harsh environments without being affected by external factors.

[0039] In summary, the present invention realizes all-round and multi-level bird repelling through energy-saving and efficient scanning mechanism, accurate bird detection and positioning, automated bird repelling operation, compact and portable design, high reliability and stability, and user-friendly operation interface. These beneficial effects not only improve the efficiency and accuracy of bird repelling, but also greatly reduce energy consumption and maintenance costs, and have broad application prospects and market value.

[0040] The radar antenna of the Doppler radar 202 protrudes from the end surface of the housing 201 and is covered by a circular cover.

[0041] Advantages of the protruding antenna setting: (1) Improved detection range and accuracy. Wider field of view: The protruding radar antenna can cover a larger detection range without being blocked by the device casing, ensuring omnidirectional propagation of the radar signal. This allows better detection of targets in the surrounding environment, whether birds or other moving objects. Reduced blind spots: The protruding radar antenna reduces the obstruction of the device itself, reduces the detection blind spots, and improves the comprehensiveness and accuracy of detection. This is especially important for applications that require all-round monitoring, such as airports and substations. (2) Enhanced signal strength. Reduced signal attenuation: The protruding radar antenna can directly transmit and receive signals, reducing the attenuation of the signal when passing through the device casing, and improving the strength and quality of the signal. Improved sensitivity: The protruding setting of the radar antenna can reduce interference in the signal path, improve the sensitivity of the radar, and help detect targets earlier and more accurately. (3) Improved environmental adaptability. Better heat dissipation: The protruding radar antenna is easier to dissipate heat, especially in high temperature environments, which can maintain the normal operating temperature of the radar and extend the service life of the equipment. Reduced water accumulation and dirt: The protruding radar antenna can reduce the accumulation of impurities such as rainwater and dust, keep the radar surface clean, and ensure the normal operation of the radar. (4) Simplify installation and maintenance. Easy installation: The protruding radar antenna is easier to install and does not require complicated internal wiring and fixing, which reduces installation time and cost. Easy maintenance: The protruding setting of the radar antenna makes maintenance and cleaning more convenient, and the radar module can be quickly checked and replaced, reducing downtime. (5) Enhance physical protection. Reduce internal damage: The protruding radar antenna can be designed with a certain physical protection structure, such as a protective cover or anti-collision design, to reduce damage to the radar caused by external impact. Avoid internal interference: The protruding setting of the radar antenna can reduce the interference of other electronic components inside the equipment to the radar signal, thereby improving the stability and reliability of the system.

[0042] The design of the circular cover: (1) Protect the radar antenna. Physical protection: The circular cover can effectively protect the radar antenna from physical damage, such as impact, scratches, etc. This is especially important in outdoor environments and can extend the service life of the radar antenna. Waterproof and dustproof: The circular cover can ensure that the radar antenna has good waterproof and dustproof performance and meets the protection standards of IP67 or higher. This can ensure the normal operation of the radar antenna under severe weather conditions such as rain, snow, sandstorms, etc. (2) Optimize signal transmission. Transparent materials: The circular cover is usually made of transparent materials, such as acrylic or special plastics. These materials have little effect on the transmission of radar signals and can ensure the omnidirectional propagation and reception of radar signals. Signal calibration: During the installation and debugging process, the radar signal can be calibrated by adjusting the position and angle of the circular cover to ensure the accuracy and consistency of the radar signal.

[0043] Round cover design: Design a transparent protective cover on the protruding part of the radar antenna to protect the radar from physical damage without affecting the transmission of the radar signal. Waterproof and dustproof: Ensure that the protruding part of the radar antenna has good waterproof and dustproof performance, meeting the protection standard of IP67 or higher. Fixed structure: Design a sturdy fixed structure to ensure that the radar antenna can still work stably in strong wind or vibration environment. Signal calibration: During the installation and debugging process, calibrate the radar signal to ensure the accuracy and consistency of the radar signal. Through these design and implementation suggestions, the advantages of the protruding radar antenna can be fully utilized to improve the performance and reliability of the fully automatic bird repellent device.

[0044] The three-axis rotating arm 102 includes a first rotating arm 102a connected to the base 101, on which a first motor 102b for controlling the rotation thereof is arranged; a second rotating arm 102c connected to the first rotating arm 102a, on which a second motor 102d for controlling the rotation thereof is arranged; and a mounting member 103 connected to the second rotating arm 102c, on which a third motor 102e for controlling the rotation thereof is arranged. The bird-repelling component 200 is mounted on the mounting member 103.

[0045] Specifically, the first rotating arm 102a can be rotated in a horizontal plane (i.e., in the X-axis direction) by the drive of the first motor 102b to achieve a wide range of horizontal movement. The second rotating arm 102c can be rotated in a vertical plane (i.e., in the Y-axis direction) by the drive of the second motor 102d to achieve movement in the up and down directions. The mounting member 103 can be rotated in another vertical plane (i.e., in the Z-axis direction) by the drive of the third motor 102e to achieve movement in the front and back directions. This multi-axis linkage design not only improves the flexibility and range of motion of the robot arm, but also ensures its precise operation ability in complex environments. For example, in a security monitoring system, the three-axis rotating arm 102 can ensure that the bird-repelling component 200 is fully monitored at different angles and positions, avoiding the problem of camera angle deviation caused by bird activities, thereby ensuring the stability and reliability of the monitoring effect.

[0046] The actuator 203 includes a player, an ultrasonic generator and a laser generator, wherein the player is integrated in the housing 201 , and the ultrasonic generator and the laser generator can be extended and plugged outside the housing 201 .

[0047] The actuator 203 is a multifunctional bird-repelling device, which is designed to effectively repel birds through various means to ensure the safety and normal operation of a specific area. The actuator 203 includes a player, an ultrasonic generator, and a laser generator, wherein the player is integrated in the housing 201, and the ultrasonic generator and the laser generator can be extended and plugged into the outside of the housing 201. This modular design allows users to choose the appropriate bird-repelling method according to actual needs, which is flexible and economical.

[0048] Specifically, the player is the core component of the actuator 203, which is integrated in the housing 201 and is mainly used to play the calls of the natural enemies of birds, the wailing of birds when attacked, or other high-frequency sounds that are offensive to birds. This method effectively drives away birds by simulating threatening sounds in the natural environment, and it is low-cost and easy to operate. In most application scenarios, a good bird-repelling effect can be achieved by using only the player, so it is a commonly used bird-repelling method.

[0049] However, in some special cases, the player alone may not be enough to completely drive away the birds. In this case, you can consider expanding the use of ultrasonic generators and laser generators and other methods. Ultrasonic generators emit ultrasonic waves of a specific frequency to make birds feel uncomfortable and leave the area. Laser generators emit green laser beams to stimulate the visual system of birds, causing them to fly away quickly. Although these two methods are effective, the equipment cost is relatively high and the maintenance is complicated, so they are usually used as supplementary means. For example, in places with extremely high safety requirements such as airports and substations, players, ultrasonic generators and laser generators can be used in combination to ensure a full-range and multi-level bird-repelling effect.

[0050] In summary, the design of actuator 203 fully considers the needs in different scenarios. Through modular design, users can choose the most suitable bird-repelling method according to actual conditions. The player, as a basic component, is low-cost and effective, and is the first choice in most scenarios. The ultrasonic generator and laser generator, as optional expansion modules, are suitable for special occasions with higher requirements for bird-repelling effects. Although the cost is higher, they can provide more comprehensive protection.

[0051] Example 2

[0052] Reference Figure 1-Figure 4, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: in order to better quickly disassemble and assemble the bird-repelling component 200 and ensure that it is firmly installed, a receiving shell 104 is designed to accommodate the shell 201 of the bird-repelling component 200. At the same time, the radar antenna of the Doppler radar 202 is protruding and circular, and an extrusion fixture 105 is also designed. By utilizing the thrust for installation into the receiving shell 104, the protruding radar antenna is inserted into the extrusion fixture 105, so that the extrusion fixture 105 is extruded and deformed to clamp the protruding radar antenna in a ring shape, and at the same time, the plug 105f on the extrusion fixture 105 is plugged into the jack on the bird-repelling component 200, so that the bird-repelling component 200 is electrically connected to the three-axis steering component 100, so that the processor can control the three-axis steering component 100 to steer.

[0053] The design is as follows: the mounting member 103 includes a receiving shell 104 and an extrusion clamp 105 installed on the receiving shell 104, and the extrusion clamp 105 is used for circumferential clamping of the circular cover. The extrusion clamp 105 includes a main body 105a, and two protruding and symmetrical arc-shaped portions 105b are arranged on the side of the main body 105a. A first cavity 105c is opened inside each arc-shaped portion 105b, and the first cavity 105c is partially located in the main body 105a. An arc-shaped plate 105d that can slide outward is arranged in each first cavity 105c. The two arc-shaped plates 105d are staggered up and down, and when the two arc-shaped plates 105d are extended outward to the maximum position, they form a ring with the main body 105a, which is used to clamp the circular cover from the outer wall circumferentially. The two arc-shaped portions 105b form a semicircle, and a second cavity 105e is opened at the center of the semicircle. A plug 105f that can extend outward is arranged in the second cavity 105e, and a spring 105g is arranged in the second cavity 105e and on the inner side of the plug 105f. The plug 105f corresponds to the socket on the shell 201 of the bird-repelling component 200, and the two first cavities 105c are both connected to the second cavity 105e, and the volume of the second cavity 105e is greater than the total volume of the two first cavities 105c.

[0054] It should be explained that the two first cavities 105c inside the extrusion clamp 105 are connected to the second cavity 105e, and the volume of the second cavity 105e is greater than the total volume of the two first cavities 105c. This design allows the gas in the second cavity 105e to flow smoothly into the two first cavities 105c as the plug 105f is compressed when the radar antenna is inserted, avoiding the accumulation of air pressure and ensuring that the arc plate 105d can be smoothly pushed out and extend outward along the first cavity 105c until the radar antenna is clamped in an embracing manner from the outside. This structural design not only improves the installation efficiency, but also enhances the stability and locking strength of the clamp, so that the radar antenna and the circular cover can be firmly fixed in place, and can remain stable even in harsh outdoor environments, reducing the risk of equipment failure caused by improper installation or environmental factors. In addition, this quick and simple installation method also greatly improves the convenience of maintaining and replacing the bird-repelling component 200, reduces maintenance costs, and improves the reliability and durability of the entire system.

[0055] The initial state of the extrusion fixture 105 is that the two arc plates 105d are both accommodated in their respective first cavities 105c, so that a semicircular notch is formed on the side of the main body 105a, which facilitates the circular radar antenna and the circular cover to enter therein, and at the same time, the spring 105g in the second cavity 105e is in an expanded state, thereby squeezing the plug 105f out of the second cavity 105e and protruding the semicircular notch. During the actual insertion, the rectangular shell 201 is first aligned with the receiving shell 104, and the radar antenna and the circular cover of the protruding Doppler radar 202 are aligned with the extrusion fixture 105, and then force is applied to insert it. During the insertion process, the shell 201 first enters the receiving shell 104, and then the radar antenna enters the semicircular notch of the extrusion fixture 105, and enters so that the side jack is docked with the protruding plug 105f. As the plug 105f is pushed to shrink as the insertion continues, the plug 105f slowly compresses the spring 105g, and slowly shrinks into the second cavity 105e, and the air in the second cavity 105e is compressed. The body is squeezed into the two first cavities 105c, so that the arc plate 105d located in the first cavity 105c is pushed out, so that the two arc plates 105d extend outward along their respective first cavities 105c until the radar antenna is clamped in an embracing manner from the outside, and the ends of the two arc plates 105d are crossed, and the spring 105g pin on one of them is inserted into the lock hole of the other, completing the locking of the extrusion clamp 105, and then completing the locking of the radar antenna and the circular cover of the Doppler radar 202, and also completing the locking of the entire bird-repelling component 200, thereby realizing the quick and simple installation of the bird-repelling component 200.

[0056] The remaining structures are the same as those of Example 1.

[0057] Example 3

[0058] Reference Figure 1-Figure 3 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that it is an automated bird-repelling method, which achieves accurate detection and efficient bird-repelling through the coordinated work of advanced Doppler radar 202 technology and three-axis rotating arm 102. The specific steps are as follows:

[0059] Initialization and periodic scanning

[0060] Processor controls the three-axis rotating arm 102: The processor controls the three-axis rotating arm 102 (X, Y, and Z directions) to rotate once every ten minutes. The design of the three-axis rotating arm 102 allows the device to move freely in three dimensions: horizontal, vertical, and rotation, ensuring the comprehensiveness of the scanning range and no blind spots.

[0061] Doppler radar 202 synchronous scanning: During each rotation, the processor controls the Doppler radar 202 to synchronously scan and detect the location of the bird. The Doppler radar 202 uses the Doppler effect to determine the speed and location of the target through the frequency difference between the transmitted and received signals, and has high sensitivity and high accuracy.

[0062] Bird Detection and Location

[0063] Data processing and analysis: Doppler radar 202 transmits the detected data to the processor, which analyzes the data through algorithms to determine the specific location and activity trajectory of the birds. The processor can distinguish between birds and other non-biological targets to avoid misjudgment.

[0064] Stop rotation and keep position: When the processor detects that the bird is within the range to be driven away, it immediately controls the three-axis rotating arm 102 to stop rotating and keep the current position. This operation ensures that the actuator 203 can accurately align with the position of the bird.

[0065] Bird repelling operation

[0066] Actuator 203 starts: The processor controls actuator 203 to perform bird-repelling operation. Actuator 203 may include multiple bird-repelling means, such as a player, an ultrasonic generator, and a laser generator. The player may play the sound of a bird's natural enemy or the cry of a bird when it is attacked, the ultrasonic generator may emit an ultrasonic wave of a specific frequency, and the laser generator may emit a green laser beam. These means may be used alone or in combination, and the most effective bird-repelling method may be selected according to the actual situation.

[0067] Continuous monitoring and feedback: During the bird repelling operation, the Doppler radar 202 continues to monitor the bird's response. If the bird is still within range, the processor will continue to control the actuator 203 to perform the bird repelling operation until the bird leaves. This process ensures the effectiveness and thoroughness of the bird repelling operation.

[0068] Resume Scan

[0069] Resuming periodic scanning: When the bird leaves the range that needs to be driven away, the processor controls the three-axis rotating arm 102 to resume periodic scanning and continue the next round of detection and bird-repelling operation.
