[0002] In many places, birds are an important ecological resource. But at the same time, birds can also cause corresponding bird damage problems. For example, if a large number of birds inhabit or appear near high-voltage lines, it may not only cause equipment failures, but also bring potential safety hazards to the birds themselves.

In addition, the conventional video monitoring method still needs to cooperate with manual screening to determine whether there is an abnormality on the scene. Manual processing and judgment also consume a lot of human resources and are inefficient. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0039] An embodiment of the present invention provides a bird-repelling device, which is suitable for repelling birds and preventing them from damaging power facilities.

[0040] Figure 1: is a structural block diagram of a bird-repelling device provided by an embodiment of the present invention, and the bird-repelling device provided by an embodiment of the present invention includes a positioning module 1, a central control module 2 and a pulse module 3. The positioning module 1 is connected in communication with the central control module 2, and the positioning module 1 is used to output a bird position identification signal to the central control module 2 when a bird is detected to enter the prevention area. The central control module 2 is also connected in communication with the pulse module 3, and the central control module 2 is used to output a pulse start signal to the pulse module 3 when receiving the bird position identification signal. The pulse module 3 is used to emit a variable frequency sound wave pulse to drive the bird out of the prevention area when receiving the pulse start signal.

[0041] The bird-repelling device is installed on the power equipment that needs to be repelled, such as the top of the power tower. When the device is turned on, the positioning module 1 will start working. Exemplarily, the positioning module 1 can be a microwave detection module, which can emit microwaves at multiple angles at intervals. By detecting the returned microwave signal, the specific coordinates of the bird in the three-dimensional coordinate system can be obtained. When the positioning module 1 detects that the bird has entered the prevention area, the central control module 2 will receive the bird position identification signal, and then the central control module 2 controls the pulse module 3 to release the variable frequency sound wave pulse.

[0042] For example, the pulse module 2 can release a variable frequency ultrasonic pulse of 20kHz-38kHz, and within a certain period of time, the pulse module 2 releases a sound wave pulse whose frequency changes from high to low or from low to high, thereby forming a number of frequency conversion cycles. Different birds have different sensitivities to sound waves of different frequencies. The ultrasonic waves formed by the sound wave pulses of constantly changing frequencies can effectively repel different types of birds.

[0043] A bird-repelling device provided in an embodiment of the present invention can monitor the position of birds and release variable-frequency sound wave pulses, making the birds feel disgusted while ensuring that the birds are not harmed, thereby improving the efficiency of bird repelling without causing damage to the ecological environment.

[0044] Figure 2 is a structural block diagram of another bird repelling device provided by an embodiment of the present invention, referring to Figure 2 Optionally, the bird repellent device further includes a magnetic field module 4, which is in communication with the central control module 2. The central control module 2 is further configured to output a magnetic field start signal to the magnetic field module 4 upon receiving the bird position identification signal. The magnetic field module 4 is configured to start continuously changing the magnetic declination in the prevention area upon receiving the magnetic field start signal.

[0045] When a bird is detected entering the prevention area, the magnetic field module 4 will be turned on, and the magnetic induction ability and direction perception ability of the bird will be weakened by changing the magnetic declination in the prevention area, and the magnetic declination within the magnetic field range will be dynamically adjusted, such as switching the magnetic declination randomly or according to a certain rule, so that the direction perception ability of the bird is disordered, thereby preventing the bird from staying near the tower and reducing the risk of line failure. The dual effects of the pulse module 3 and the magnetic field module 4 can improve the bird-repelling effect.

[0046] Figure 3 is a structural block diagram of another bird repelling device provided by an embodiment of the present invention, referring to Figure 3 Optionally, the bird-repelling device further includes a steering module 5. The central control module 2 is in communication connection with the steering module 5, and the central control module 2 is also used to control the steering module 5 to turn to the direction of the bird's position according to the bird position identification signal. The pulse module 3 is fixedly arranged on the steering module 5, and the steering module 5 is used to drive the pulse module 3 to turn to the direction of the bird's position. The steering module 5 drives the pulse module 3 to turn, thereby realizing the directional release of the sound wave pulse to the bird's position, thereby achieving the effect of accurately driving away the birds and improving the driving efficiency.

[0047] Figure 4 is a structural block diagram of another bird repelling device provided by an embodiment of the present invention, referring to Figure 4 Optionally, the bird-repelling device further includes an identification module 6, which is in communication connection with the central control module 2. The identification module 6 is used to identify the species of birds and output the species information of the birds to the central control module 2. The central control module 2 is also used to control the pulse module 3 to emit a sound wave pulse of a corresponding frequency according to the correspondence between the preset sound wave pulse frequency and the bird species after receiving the species information. In order to improve the bird-repelling effect, the correspondence between the optimal repelling sound wave frequency of different types of birds and the bird species can be set in advance. The shape and sound of the bird are identified by the identification module 6. After the bird species is identified, the preset optimal repelling sound wave frequency corresponding to the bird is retrieved to transmit a directional pulse sound wave, thereby improving the success rate of repelling different types of birds.

[0048] For example, the effective frequency of the sound wave for driving away sparrows is 30kHz-35kHz. When the recognition module 6 recognizes that the currently approaching bird is a sparrow, the pulse module generates a frequency change of the pulse between 30kHz-35kHz, thereby improving the success rate of driving away the bird. The optimal sound wave frequency for driving away other birds can be measured through experiments and pre-stored in the central processing module 2.

[0049] Optionally, the recognition module 6 includes a camera, which recognizes the species information of the bird entering the prevention area according to its appearance, and outputs the species information to the central control module 2.

[0050] Optionally, the identification module 6 includes a sound sensor, which identifies the species of birds entering the prevention area according to their calls, and outputs the bird species information to the central control module 2. Exemplarily, the sound sensors can be set on multiple power towers or nearby trees and connected to the network through a wireless network. The sound sensors on multiple power towers can play a role in regional alert.

[0051] Optionally, the positioning module 1 does not work when there are no birds approaching, and is activated when the sound sensor recognizes the bird's call to locate the bird's position, thereby saving electricity, reducing the energy consumption of the bird repellent device and improving detection reliability.

[0052] Optionally, the central control module 2 is also used to change the frequency change speed of the sound wave pulse emitted by the pulse module 3 and the magnetic declination change speed of the magnetic field module according to the bird position identification signal. For example, when the bird enters the prevention area of ​​the bird repellent device, the pulse module 3 starts to switch the frequency at a relatively slow cycle. When the bird continues to approach the bird repellent device, the pulse module 3 can increase the sound wave frequency switching speed due to the reduction in the distance of the bird, and the frequency change speed of the sound wave pulse is accelerated, so that the bird has a greater sense of disgust, so that the bird knows that it cannot continue to approach the tower and moves away on its own. Similarly, the magnetic field module 4 will increase the speed of changing the magnetic declination as the bird continues to approach the bird repellent device.

[0053] Optionally, the positioning module 1 continuously outputs a bird position identification signal to the central control module 2, and the central control module 2 evaluates the bird-repelling effect of the pulse module 3 and the magnetic field module 4 according to the position identification signal. When the sound wave pulse of the preset frequency band and / or the preset magnetic declination are detected to have a repelling effect, the sound wave pulse of the preset frequency band and / or the preset magnetic declination are continuously output. The positioning module 1 continuously tracks the flight trajectory of the birds, and judges the bird-repelling effect according to the change of the flight trajectory. If the birds have a situation such as slowing down the flight speed, deviating from the trajectory or turning around, it means that the bird-repelling device is effective. If the bird-repelling device is effective, the pulse module 3 and the magnetic field module 4 continuously output the sound wave pulse of the preset frequency band and the preset magnetic declination; if the repelling effect is not good, the frequency of the sound wave pulse and the magnetic declination of the magnetic field will be continuously changed, and the central control module 2 evaluates the bird-repelling effect in real time in combination with the change of the flight trajectory. If it is subsequently detected that an ultrasonic pulse of a certain frequency or a magnetic declination used for magnetic field interference has a repelling effect, the conversion is stopped, and the ultrasonic pulse or magnetic field interference of the above frequency is continuously output until the flock of birds is repelled.

[0054] Optionally, after the bird-repelling operation is completed, the central control module 2 will turn off the pulse module 3, the magnetic field module 4 and the steering module 5, and the device will enter a standby state.

[0055] Based on the same inventive concept, an embodiment of the present invention further provides a bird-repelling system. Figure 5is a structural block diagram of a bird-repelling system provided by an embodiment of the present invention. Figure 6 is a working logic diagram of a bird-repelling system provided by an embodiment of the present invention, with reference to Figure 5 and Figure 6 As shown, the bird-repelling system includes at least two bird-repelling devices provided by any embodiment of the present invention, and the bird-repelling system also includes a communication module 7. The central control modules in at least two bird-repelling devices arranged in different prevention areas exchange bird position information through the communication module 7. Specifically, Figure 5 As shown, the first central control module 9 in the first bird-repellent device 14 and the second central control module 12 in the second bird-repellent device 15 are respectively connected to the communication module 7 for communication. Exemplarily, if the first positioning module 8 detects that a bird has entered the prevention area, the first positioning module 8 will output a bird position identification signal to the first central control module 9. After receiving the bird position identification signal, the first central control module 9 will output the bird position identification signal to the communication module 7. The communication module 7 will then output the bird position identification signal to the second central control module 12, thereby sharing the bird position information among multiple bird-repellent devices. Optionally, multiple bird-repellent devices are divided into a group of joint prevention and control areas, and these bird-repellent devices exchange information through the communication module 7. Exemplarily, refer to Figure 5 , if the flock of birds approaches the corresponding power tower area, the first bird-repelling device 14 on the first power tower closest to the flock of birds detects the birds through the first positioning module 8. At this time, the first positioning module 8 will continue to identify the flight trajectory of the flock of birds and output the flight trajectory information of the flock of birds to the first central control module 9. The first central control module 9 determines the towers that the flight trajectory of the flock of birds will pass through. For example, the towers within 100 meters of the flight trajectory of the flock of birds are considered to be passed by the flock of birds. If the flight trajectory of the flock of birds passes through the second bird-repelling device 15, the first central control module 9 will output the warning signal to the second central control module 12 through the communication module 7. The second central control module 12 pre-starts the second positioning module 11 and the second pulse module 13 to release directional sound wave pulses to the birds to drive them away. Then, additional driving means can be used for the flock of birds, such as flashing lights to strengthen the driving of the flock of birds, so that the flock of birds will have as much disgust as possible. The first positioning module 8 and the second positioning module 11 continuously track the flight trajectory of the birds, and the first central control module 9 and the second central control module 12 determine the effect of bird repelling according to the changes in the flight trajectory fed back by the first positioning module 8 and the second positioning module 11. If the first positioning module 8 and the second positioning module 11 cannot detect the birds, it means that the flock of birds has moved away from the current tower area, and the joint defense and repelling is terminated.

[0056] Based on the same inventive concept, the embodiment of the present invention further provides a bird-repelling method, which is applicable to the bird-repelling system provided in the embodiment of the present invention, and is combined with Figure 5 and Figure 6As shown, the bird repelling system includes a first bird repelling device 14 and a second bird repelling device 15 . The first bird repelling device 14 includes a first positioning module 8 and a first central control module 9 . The second bird repelling device 15 includes a second positioning module 11 , a second central control module 12 and a second pulse module 13 .

[0057] Figure 7 is a flow chart of a bird-repelling method provided by an embodiment of the present invention, with reference to Figure 6 and Figure 7 , bird repellent methods include:

[0058] S701. The first central control module determines the second bird-repelling device included in the flight track of the bird according to the first bird position identification signal output by the first positioning module, and sends an early warning signal to the second central control module through the communication module.

[0059] S702. The second central control module starts the second positioning module and the second pulse module according to the early warning signal, and outputs a pulse start signal to the second pulse module according to the second bird position identification signal output by the second positioning module, so as to control the second pulse module to emit variable frequency sound wave pulses to drive the birds out of the prevention area.

[0060] For example, reference Figure 5 and Figure 6 If the first positioning module 8 of the first bird-repelling device 14 on an electric tower detects a bird, and the first central control module 9 determines that the bird is flying to other electric towers through the bird flight data obtained by the first positioning module 8, it can send an early warning signal to the second central control module 12 of the second bird-repelling device 15 on the electric tower where the bird's flight trajectory is about to fly, forming a joint prevention and control bird-repelling strategy. The coordinated bird-repelling strategy of multiple electric towers can improve the effect of driving away a large number of bird flocks to a greater extent compared to the bird-repelling strategy implemented by a single electric tower alone. The bird-repelling method provided in the embodiment of the present invention combines the bird-repelling strategy of the joint prevention and control of multiple electric towers, can effectively drive away a large number of bird flocks, and make the driving efficiency of bird flocks higher through more intelligent control means.

[0061] The above specific implementations do not constitute a limitation on the scope of protection of this invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made according to design requirements and other factors.
