Description

Technical Field

[0001] This utility model relates to the field of railway bird deterrence technology, and in particular to a railway bird deterrence device based on multi-sensor fusion. Background Technology

[0002] A railway bird deterrent device is a device installed along railway lines and related facilities to drive away birds. Its main function is to prevent birds from moving around in railway areas and to avoid affecting railway operation safety and normal equipment operation due to bird collisions with trains or nesting on railway equipment. Common railway bird deterrent devices use a variety of methods, including physical, auditory, and visual bird deterrents, such as ultrasonic bird deterrents, reflective bird deterrents, and simulated animal bird deterrents. Through continuous and effective deterrence, these devices reduce the number of birds staying in key railway areas, ensuring the safety, efficiency, and stability of railway transportation.

[0003] A search revealed Chinese patent publication number CN221306980U, which discloses a bird-repelling device for railway lines. The device includes an L-shaped base with a V-shaped base fixedly connected to its rear surface for mounting on a post. Two tightening clamps for locking are fixedly connected to both sides of the V-shaped base. A movable capturing device is fixedly connected to the upper surface of the L-shaped base. A small gear on the left rotates in the opposite direction, causing the first partial gear to rotate in the opposite direction simultaneously. This causes the wiping cloth strip on the wiping plate to swing back and forth on the bird-repelling camera, wiping the lens surface to remove dust. This structure effectively cleans dust and dirt from the lens, improving the overall stability of the device and preventing stubborn stains from affecting the accuracy of the bird-repelling camera. While microwave radar has strong resistance to environmental interference, complex backgrounds can affect its detection accuracy. Currently, using only microwave radar sensors for detection can easily lead to inaccurate judgments. Utility Model Content

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a railway bird deterrent device based on multi-sensor fusion, comprising a housing 1. The housing 1 has at least three continuously connected surfaces: a first surface, a second surface, and a third surface, each facing a different direction. Microwave radar 9 is installed on the first and third surfaces, and infrared radar 14 and a photoresistor 16 are installed on the second surface. The installation of the infrared radar 14 ensures accurate detection of birds. The photoresistor 16 is electrically connected to the microwave radar 9 and the infrared radar 14, and is used to detect daytime and nighttime environments, activating the microwave radar 9 and the infrared radar 14 during the day and deactivating them at night. Multiple circular grooves 6 are equidistantly spaced at the upper and lower ends of the front left side of the housing 1, and multiple circular holes 15 are equidistantly spaced at the bottom left side of the housing 1. A second solar panel 13 is installed on the left and right sides of the rear side of the box 1. A first solar panel 3 is installed on the top of the box 1. Indicator lights 11 are installed on the front and rear ends of the top left side of the box 1. The working status of each device can be displayed by the installation of the indicator lights 11. A power switch 21 is installed on the left side of the bottom of the box 1. Support rods 7 are fixedly connected to the left and right ends of the bottom of the support plate 204. A rotating circular plate 8 is rotatably connected to the middle of the support rod 7. An installation clip 17 is installed in the middle of the bottom of the box 1. Bolts 19 are threadedly connected to the left and right ends of the installation clip 17. The installation of the installation clip 17 facilitates the installation of this device. Connecting circular rods 18 are fixedly connected to the left and right ends of the bottom of the installation clip 17. Installation rods 20 are installed on the left and right ends of the bottom of the connecting circular rods 18. The installation of the installation rods 20 ensures that this device can be installed stably.

[0040] Specifically, multiple circular slots 6 are provided at the top to allow sound to propagate through these openings. Similarly, the circular slots 6 at the bottom allow ultrasonic energy to be emitted. Indicator lights 11 are installed to display the working status of each device. In addition, multiple circular holes 15 allow ultrasonic waves to be emitted. The installation of infrared radar device 14 ensures that birds can be accurately detected. To prevent birds from approaching, the system uses voice, ultrasonic waves, or strong LED lights to drive them away. The installation of a first solar panel 3 and two second solar panels 13 ensures that all devices will not stop working due to insufficient power. The photoresistor 16 is electrically connected to the microwave radar 9 and the pyroelectric induction radar to ensure that they only work during the day and not at night, thus avoiding nighttime interference with residents. Through the above process, the combination of the large detection radius but low accuracy of microwave radar 9 and the small detection radius but high accuracy of pyroelectric induction radar improves the accuracy of bird detection and thus achieves the goal of repelling birds.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The housing 1 also includes a clamping mechanism 2 and a support plate 204. The clamping mechanism 2 is installed on the top front side of the housing 1. The support plate 204 is fixedly connected to the middle of the left front side of the housing 1. A slide bar 202 is fixedly connected to the upper middle of the left front side of the housing 1. A clamping plate 205 is slidably connected to the left and right front sides of the slide bar 202. A bidirectional threaded rod 203 is threadedly connected to the bottom of the clamping plate 205. A limiting circular plate 206 is fixedly connected to the left and right sides of the bidirectional threaded rod 203. A remote control 201 is installed at the top center of the support plate 204. An antenna 207 is installed on the top of the remote control 201. The installation of the remote control 201 facilitates the operation of the device. An installation block 12 is installed on the top right side of the housing 1. A handle 23 is fixedly connected to the right end of the right limiting circular plate 206. The installation of the handle 23 facilitates the rotation of the bidirectional threaded rod 203.

[0042] Specifically, when operating the remote control clamping device 201, first rotate the handle 23, which will cause the bidirectional threaded rod 203 to rotate. As the bidirectional threaded rod 203 rotates, the clamping plates 205 on the left and right sides will slide in opposite directions on the slide bar 202, thereby clamping or releasing the remote control 201. The remote control 201 can remotely control related operations, while the antenna 207 improves the efficiency of signal transmission. The installation of the support plate 204 ensures that the remote control 201 can be placed stably to prevent it from falling during transportation.

[0043] Reference Figure 1 , Figure 2 and Figure 3The bottom rear end of the box 1 is provided with a charging slot 22. Warning lights 10 are installed on the lower middle part of the left and right sides of the front of the box 1. A card slot plate 5 is fixedly connected to the middle of the top of the front of the box 1. A notice board 4 is set inside the card slot plate 5.

[0044] Specifically, the charging slot 22 facilitates the charging of this device, the warning light 10 facilitates the display of the device's status, the card slot plate 5 facilitates the replacement of the notice board 4, and the notice board 4 facilitates the reminder to staff.

[0045] Working principle: Multiple circular slots 6 at the top allow multiple voice signals to be emitted, and multiple circular slots 6 at the bottom allow ultrasonic energy to be emitted. Indicator lights 11 display the working status of each device. Multiple circular holes 15 allow ultrasonic waves to be emitted. Infrared radar 14 accurately detects birds and uses voice, ultrasonic waves, or strong LED lights to deter birds from approaching. The first solar panel 3 and two second solar panels 13 prevent insufficient power for each device. The photoresistor 16 is electrically connected to the microwave radar 9 and the pyroelectric induction radar, making it active during the day and inactive at night to avoid disturbing residents. Through the above process, the microwave radar 9 has a large detection radius but is not accurate enough, while the pyroelectric induction radar has a small detection radius but is accurate. The combination of the two can effectively improve the accuracy of bird detection and thus accurately drive away birds.

[0046] When it is necessary to clamp the remote control 201, first turn the handle 23 to make the bidirectional threaded rod 203 start to rotate. The rotation of the bidirectional threaded rod 203 causes the clamping plates 205 on the left and right sides to slide on the slide bar 202 in opposite or opposite directions, thereby clamping or releasing the remote control 201. The remote control 201 can remotely control related operations, and the antenna 207 enhances the signal transmission capability. The installation of the support plate 204 ensures that the remote control 201 can be placed stably to prevent it from falling during transportation.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
