Description

Technical Field

[0001] The utility model relates to the technical field of bird-repelling devices, in particular to a bird-repelling device based on bird sound patterns and infrared monitoring. Background Art

[0002] Overhead transmission lines are mostly far away from human activity areas. Birds like to defecate, build nests, and peck on transmission towers, causing damage to transmission equipment or line tripping and failure shutdown, which is called bird damage. In the prior art, in order to prevent bird damage to transmission equipment, bird repellent devices are generally installed near transmission equipment to drive away birds. Specifically, radar is generally used to detect whether there are birds staying nearby, and then light waves, sound waves, or ultrasonic waves are activated to drive away birds.

[0003] The Chinese patent application number 202321015929.2 discloses a bird-repelling device for high-voltage lines. The bird-repelling device monitors bird activity traces through radar and microphones, and then drives birds away through laser, sound waves, ultrasound, stroboscopic light and other methods. Although this solution can solve the long-term adaptability problem of birds, since the bird-repelling device is installed near the high-voltage power grid, the high-voltage power grid will generate electromagnetic interference to the device, especially the radar in the bird-repelling device. First, the electromagnetic field generated by the high-voltage power line may cause electromagnetic interference to the radar signal, especially when the frequency is close, affecting the performance of radar monitoring; second, the radar wave will be reflected from the metal structure of the power line (such as towers and wires), generating additional echoes, which may cover or interfere with the signals of other targets, resulting in inaccurate bird target monitoring.

[0004] The purpose of this utility model is to design a bird repellent device based on bird soundprints and infrared monitoring in order to solve the above problems in the prior art. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a bird repelling device based on bird sound patterns and infrared monitoring, which can solve the above-mentioned technical problems.

[0006] The utility model provides a bird-repelling device based on bird sound patterns and infrared monitoring, which is installed on the top of a high-voltage power tower. The bird-repelling device comprises:

[0007] A microphone array for acquiring bird audio and the location of the bird audio;

[0008] An infrared imaging sensor, driven by a rotating assembly, is used to obtain infrared thermal images of birds;

[0009] A controller, connected to the microphone array and the rotating assembly, respectively, for controlling the rotating assembly to rotate to the position of the bird audio according to the position of the bird audio acquired by the microphone array;

[0010] The rotating assembly is used to drive the infrared imaging sensor to rotate to the location of the bird audio;

[0011] The controller is connected to the infrared imaging sensor and is used to match the corresponding bird-repelling audio according to the red thermal imaging result obtained by the infrared imaging sensor and the bird audio obtained by the microphone array;

[0012] The controller is connected to a loudspeaker for forwarding the bird-repelling audio to the loudspeaker for playing.

[0013] Furthermore, the bird-repelling device is connected to a photovoltaic component, and the photovoltaic component is arranged on the top of the high-voltage tower and is used to supply power to the bird-repelling device through the photovoltaic component.

[0014] Furthermore, the photovoltaic assembly includes: a photovoltaic bracket, a photovoltaic panel, and an energy storage battery;

[0015] The photovoltaic panel is arranged on the front side of the photovoltaic support for obtaining solar energy; the photovoltaic panel is connected to the energy storage battery for converting solar energy into electrical energy; the energy storage battery is connected to the bird-repelling device for providing electrical energy.

[0016] Furthermore, an extension rod is provided at the rear side of the photovoltaic support, and a rotating assembly is fixed on the extension rod;

[0017] The inner side of the photovoltaic support is used for placing the loudspeaker, and a multimedia box is arranged on the inner side of the photovoltaic support for placing the energy storage battery and the controller.

[0018] Further, the rotating assembly includes: a rotating mechanism and a rotating motor;

[0019] The rotating motor is connected to the controller for obtaining a rotation instruction; the rotating motor is connected to the rotating mechanism for driving the rotating mechanism to rotate according to the rotation instruction, and the rotating mechanism can rotate 360° horizontally.

[0020] Furthermore, the microphone array is arranged above the rotating component.

[0021] Furthermore, the infrared imaging sensor is arranged on a side of the rotating component.

[0022] Furthermore, the microphone array is an 8-microphone circular array.

[0023] The utility model has the following advantages:

[0024] First, since radar is easily interfered with on high-voltage power grids, microphone arrays and infrared imaging sensors are less susceptible to electromagnetic interference. Therefore, in this embodiment, microphone arrays and infrared imaging sensors are used for monitoring. The controller microphone array monitors the bird audio and the direction of the bird audio, and the infrared imaging sensor confirms whether there are birds on the high-voltage power grid, thereby ensuring the accuracy of the monitoring results.

[0025] The second is to set the infrared imaging sensor on the rotating component, control the rotating component to rotate to the corresponding position according to the direction of the bird audio, and start the infrared imaging sensor. If the infrared imaging sensor obtains the infrared thermal image of the bird, it means that there is a bird at that position, which can effectively avoid the false detection of bird audio by the microphone array.

[0026] The third is to set the infrared imaging sensor and microphone array above the extension pole of the photovoltaic module to ensure that the infrared imaging sensor and microphone array will not be blocked by other obstructions during monitoring, thereby ensuring the accuracy of monitoring.
