Description

Technical Field

[0001] The present invention relates to the field of navigation technology, and in particular to a self-cleaning bird-repelling system applied to a navigation mark and a navigation mark having the same Background Art

[0002] A beacon is the abbreviation of an aid to navigation. It refers to a sign indicating the direction, boundary and obstruction of a waterway. It is an artificial sign that helps guide ships, locate and mark obstructions and warns. Since the beacon is always in an open-air environment, a large number of birds often appear around it. If it is not driven away in time, the bird droppings produced by the birds will fall on the beacon, which will not only affect the appearance of the beacon, but also have a serious impact on its performance and life. Therefore, it is necessary to drive away the birds around the beacon to prevent them from approaching the beacon.

[0003] At present, in terms of bird repellent technology, there are mainly bird repellent spikes, bird repellent original drug bags, wind-powered bird repellents, sound bird repellents and other methods. Among them, the scope of action of bird repellent spikes is limited, usually only covering the surface it directly contacts, and may have limited effect on larger areas of bird habitats; bird repellent original drug bags, wind-powered bird repellents and sound bird repellents are easily affected by bad weather and strong winds and waves, and the bird repellent effect is usually poor; and although laser bird repellent is less affected by the environment, the laser may disrupt the sight of people on passing ships and damage their eyesight, so it is not suitable for use on waterways. In addition, at present, bird droppings on navigation marks are usually cleaned manually, which is not only inefficient and costly, but also because the bird droppings on navigation marks appear at short intervals, they need to be cleaned and maintained very frequently, making the daily maintenance of navigation marks more difficult and the economic cost sharply increased. Therefore, the traditional single treatment method can no longer meet the needs of green and sustainable development of navigation mark industry. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a self-cleaning bird-repelling system for use in a navigation mark and a navigation mark having the same.

[0005] A self-cleaning bird-repelling system comprises: an intrusion monitoring module, which divides an intrusion area prohibited for birds to enter based on the position of a navigation mark and monitors the intrusion area in real time; a navigation mark monitoring module, which monitors the surface of the navigation mark in real time; an analysis module, which is respectively connected to the intrusion monitoring module and the navigation mark monitoring module for analyzing the monitoring information and generating a control signal; an ultrasonic bird-repelling module, which is used to emit an ultrasonic wave to drive the birds away from the intrusion area; a water spraying module, which is used to spray water on the surface of the navigation mark, so as to rinse and clean the navigation mark, and drive away the birds resting on the navigation mark by the water flow; and a control module, which is respectively connected to the analysis module, the ultrasonic bird-repelling module and the cleaning module for receiving the control signal of the analysis module and generating a control instruction according to the control signal to control the ultrasonic bird-repelling module and the cleaning module.

[0006] In the above technical solution, the intrusion monitoring module and the navigation mark monitoring module share their monitoring information with the analysis module in real time. After analyzing and judging the monitoring information, the analysis module generates a control signal according to a preset strategy, and transmits the signal to the control module, so that the control module controls the ultrasonic bird repellent module and the water spray module. The specific principle is that the intrusion monitoring module takes the navigation mark as a reference and plans an intrusion area where birds are prohibited from flying around the navigation mark. When birds enter the intrusion area, the control module controls the ultrasonic bird repellent module to emit ultrasonic waves to drive away the birds flying into the intrusion area until the birds leave the intrusion area. The navigation mark detection module is used to monitor the surface of the navigation mark. When birds are detected on the surface of the navigation mark, the control module controls the water spray module to spray water, and drives away the birds resting on the navigation mark through water flow. When bird droppings are detected on the surface of the navigation mark, the control module also controls the water spray module to spray water, and the bird droppings attached to the navigation mark are washed by water flow to achieve self-cleaning of the navigation mark.

[0007] Furthermore, the monitoring information processing process of the intrusion monitoring module is as follows: preprocessing the image data monitored by the intrusion monitoring module; the analysis module identifies and judges the bird features in the preprocessed image, and generates a corresponding control signal; the control signal is transmitted to the control module, and the control module generates a corresponding control instruction.

[0008] In the above technical solution, the image information monitored by the intrusion monitoring module is shared with the analysis module in real time. The analysis module pre-processes the image data first. The pre-processing mainly includes removing random noise in the image and enhancing the contrast of the image to facilitate subsequent feature extraction and recognition. The analysis module has a built-in learning model. The model has pre-learned and trained the bird image data that often appears around the waterway, so that the type of bird can be judged according to the input image features. The analysis module generates a corresponding control signal based on the bird type identified by the model and passes it to the control module.

[0009] Furthermore, the ultrasonic bird-repelling module emits ultrasonic waves of different frequencies according to different control instructions of the control module.

[0010] In the above technical solution, since birds of different sizes and species are sensitive to different ultrasonic segments, the control module generates different control instructions based on the different control signals issued by the analysis module after determining the bird species, thereby controlling the ultrasonic module to emit ultrasonic waves of different frequencies to drive away specific bird species, which can effectively improve the bird-repelling effect.

[0011] Furthermore, the analysis module performs two types of identification analysis on the monitoring information of the navigation mark monitoring module, one is the identification of bird characteristics, and the other is the identification of bird droppings coverage. The analysis module generates different control signals according to different identified situations.

[0012] In the above technical solution, the navigation mark monitoring module monitors the surface of the navigation mark and transmits the image information to the analysis module. When the analysis module recognizes that there are birds in the image, the control module controls the water spray module to spray water to drive away the birds resting on the navigation mark through the water flow. When the analysis module recognizes that there are bird droppings in the image, the coverage rate of the bird droppings in the image is calculated. When the preset coverage rate is reached, the control device controls the water spray module to spray water to clean the bird droppings.

[0013] Furthermore, the water spray module includes multiple groups of nozzles, and each group of nozzles independently performs water spraying work under the control of the control module.

[0014] In the above technical solution, each group of nozzles can spray water independently under the control of the control module to meet the water spraying requirements for the designated part of the navigation mark.

[0015] Furthermore, the navigation mark detection module divides the monitoring image of the navigation mark surface into multiple areas, the water spray module is equipped with a group of nozzles in each area, the analysis module generates different control signals based on the monitoring information in different areas, and the control module controls the nozzles in the corresponding areas to spray water according to the control signals.

[0016] In the above technical solution, the image monitored by the navigation mark monitoring module is divided into multiple areas, and each area is provided with a group of nozzles that can spray water on the surface of the area. When birds or bird droppings are detected in the area, the control module controls the nozzles in the area to spray water to drive away the birds and clean the bird droppings.

[0017] A navigation mark comprises a float, a mounting frame arranged on the float, and a monitoring device, an ultrasonic device, a water spraying device and a control device arranged on the mounting frame. The monitoring device is installed on the outside of the mounting frame and is used to monitor and detect the float and the surrounding environment. The ultrasonic device is installed in the mounting frame and is used to emit ultrasonic waves to drive away birds. The water spraying device comprises a diversion mechanism, on which a plurality of groups of nozzles are installed, and the plurality of groups of nozzles are respectively oriented in different directions on the top of the float. The control device is respectively connected to the ultrasonic device, the monitoring device and the water spraying device for communication.

[0018] In the above technical solution, the interior of the mounting frame is hollow, the ultrasonic device is installed in the mounting frame, and the monitoring device is located outside the mounting frame. The monitoring device has two functions. One is to monitor birds. When the monitoring device finds that birds have invaded the vicinity of the navigation mark, the control device controls the ultrasonic device to start and start to emit variable frequency ultrasonic waves to drive away the birds. When the monitoring device finds that birds are stationed on the floating body, the control device controls the water spraying device to start and make the nozzle start to spray water to drive away the birds stationed on the floating body. The second is to monitor bird droppings. The monitoring device can generate an image of the top of the floating body and monitor it, identify the proportion and accumulation of bird droppings on the top of the floating body in the image, and when the bird droppings accumulate to a preset degree, the control device controls the water spraying device to start, and the nozzle flushes the top of the floating body by spraying water to achieve a cleaning effect, so as to avoid the long-term accumulation of bird droppings and corrosion of navigation mark facilities. Among them, the water spraying device is provided with a plurality of groups of nozzles, each group of nozzles can spray water independently, so that water can be sprayed only on areas where bird droppings exist and birds are stationed.

[0019] Furthermore, the monitoring device includes at least two groups of monitoring units, and each group of monitoring units includes a plurality of monitoring components.

[0020] In the above technical solution, different monitoring units have different functions. Some monitoring units are used to monitor the accumulation of bird droppings on the floating body to ensure that the water spray device can flush and clean the bird droppings. Other monitoring units are used to monitor whether there are bird invasions near the navigation mark and whether there are birds staying on the floating body.

[0021] Furthermore, the water spraying device also includes a water pump, which is provided with a water suction pipe inserted under the water surface of the waterway. The water pump is connected to the diversion mechanism through a pipeline to supply water to the diversion mechanism.

[0022] In the above technical solution, when the navigation mark floats on the water surface, the water pump is inserted below the water surface, so that the water pump can directly pump water through the water pump, thereby supplying water to the diversion mechanism and the nozzle thereon.

[0023] Furthermore, an annular frame is arranged around the outer side of the mounting frame, and bird-repelling spikes are wound and installed on the annular frame.

[0024] In the above technical solution, the annular frame is arranged around the outer circumference of the mounting frame, and the bird-repelling spikes wound thereon are used to prevent birds from approaching and staying, thereby further enhancing the bird-repelling effect.

[0025] Compared with the prior art, the beneficial effects of this application are: The bird-repellent system of the present application is provided with an intrusion monitoring module and a navigation mark monitoring module, which can monitor the navigation mark and the surrounding environment of the navigation mark in real time to ensure timely response when birds invade. At the same time, the present application is provided with an ultrasonic bird-repellent module and a water spray module. Through the combination of ultrasonic waves and water flow, birds can be effectively repelled, and the water spray module can flush the bird droppings on the surface of the navigation mark according to the monitoring information, so that the navigation mark has a self-cleaning function, and there is no need for manual frequent cleaning and maintenance of the navigation mark, which effectively reduces the maintenance cost of the navigation mark.

[0026] The navigation mark of the present application is provided with a monitoring device to monitor the surrounding area of ​​the navigation mark. When the monitoring device detects that birds are approaching the navigation mark or resting on the buoy of the navigation mark, the birds are driven away by an ultrasonic device and a water spray device respectively. The bird-repelling effect is good and the reliability is high. At the same time, the monitoring device can also detect the accumulation of bird droppings on the buoy, and the buoy is sprayed and flushed by the water spray device to avoid the accumulation of bird droppings. There is no need for frequent cleaning and maintenance of the navigation mark manually, which greatly reduces the maintenance cost of the navigation mark and has better practicality.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Example 1

[0037] The present embodiment provides a self-cleaning bird-repellent system, which is applied to a navigation mark, and includes: an intrusion monitoring module, which divides an intrusion area that birds are prohibited from entering based on the location of the navigation mark, and monitors the intrusion area in real time; a navigation mark monitoring module, which monitors the surface of the navigation mark in real time; an analysis module, which is respectively communicated with the intrusion monitoring module and the navigation mark monitoring module, and is used to analyze the monitoring information and generate a control signal; an ultrasonic bird-repellent module, which is used to emit ultrasonic waves to drive birds away from the intrusion area; a water spray module, which is used to spray water on the surface of the navigation mark, rinse and clean the navigation mark, and drive away birds that rest on the navigation mark by water; a control module, which is respectively communicated with the analysis module, the ultrasonic bird-repellent module and the cleaning module, and is used to receive the control signal of the analysis module, and generate a control instruction based on the control signal to control the ultrasonic bird-repellent module and the cleaning module.

[0038] In this embodiment, the intrusion monitoring module and the navigation mark monitoring module share their monitoring information with the analysis module in real time. After analyzing and judging the monitoring information, the analysis module generates a control signal according to a preset strategy, and transmits the signal to the control module, so that the control module controls the ultrasonic bird repellent module and the water spray module. The specific principle is that the intrusion monitoring module takes the navigation mark as a reference and plans an intrusion area where birds are prohibited from flying around the navigation mark. When birds enter the intrusion area, the control module controls the ultrasonic bird repellent module to emit ultrasonic waves to drive away the birds flying into the intrusion area until the birds leave the intrusion area. The navigation mark detection module is used to monitor the surface of the navigation mark. When birds are detected on the surface of the navigation mark, the control module controls the water spray module to spray water, and drives away the birds resting on the navigation mark through water flow. When bird droppings are detected on the surface of the navigation mark, the control module also controls the water spray module to spray water, and the bird droppings attached to the navigation mark are washed by water flow to achieve self-cleaning of the navigation mark.

[0039] In other words, the navigation mark monitoring module has two functions, one is to monitor the birds' stay on the navigation mark, and the other is to monitor the coverage of bird droppings on the navigation mark. The control module controls the operation of the water spraying device 6 according to the monitoring information of the navigation mark detection module.

[0040] In this embodiment, the system processes the monitoring information of the intrusion monitoring module as follows: S1: Preprocess the image data monitored by the intrusion monitoring module. The preprocessing mainly includes: using mean filtering, median filtering and other methods to remove random noise in the image, and then highlighting the bird features in the image through histogram equalization, contrast enhancement and other technologies to facilitate subsequent feature extraction and recognition, such as enhancing the color, texture and other features of the bird, and finally performing normalization operations such as resizing and color space conversion on the image to eliminate changes in the image caused by factors such as lighting and angle, so that the images collected under different conditions are comparable and provide a unified input format for subsequent feature extraction.

[0041] S2: The analysis module identifies and judges the bird features in the preprocessed image, and generates different control signals according to the identified bird species. The analysis module is pre-set with a trained model. First, a large amount of image data of bird species that are known to appear frequently around the waterway is collected, and these images are annotated by professionals. According to the specific application scenario and data characteristics, a suitable deep learning model architecture is selected, such as AlexNet, VGG, ResNet, etc., and the model is initialized. Then, the selected model is trained using the annotated bird image data. By continuously adjusting the model parameters, the model learns the mapping relationship between the characteristics of birds and species, so that the bird species can be accurately predicted based on the input image features.

[0042] S3: The control signal is transmitted to the control module, and the control module generates a corresponding control instruction according to the control signal.

[0043] Since birds of different sizes and species are sensitive to different ultrasonic bands, the analysis module generates different control signals based on the identified bird species, and the control module generates different control instructions based on these control signals, thereby controlling the ultrasonic bird repellent module to emit ultrasonic waves of different frequencies to carry out targeted bird repelling and improve the bird repelling effect.

[0044] Specifically, when small birds such as swallows and sparrows are identified, the ultrasonic module will amplify ultrasonic waves in the 20kHz-30kHz band; when medium-sized birds such as pigeons and doves are identified, ultrasonic waves in the 30kHz-50kHz band will be amplified; when large birds such as egrets and seagulls are identified, ultrasonic waves in the 50kHz-70kHz band will be amplified; in addition, if multiple bird invasions are detected at the same time, ultrasonic waves in the three frequency bands of 20kHz-30kHz / 30kHz-50kHz / 50kHz - 70kHz will be played in a loop of 30 seconds each until there are no birds in the field of view of the intrusion monitoring module.

[0045] Preferably, when there are no birds within the field of view of the intrusion monitoring module, the ultrasonic bird repellent module will continue to play ultrasonic waves in the 50kHz - 70kHz frequency band for 5 minutes and then stop.

[0046] In this embodiment, the monitoring of the navigation mark monitoring module is divided into two functions, one is to monitor the stop of birds on the navigation mark, and the other is to monitor the coverage of bird droppings on the navigation mark. Specifically, the analysis module divides the field of view of the navigation mark monitoring module into four equal-sized areas, each area is equipped with a group of nozzles 63 with a spray direction toward the area, and each group of nozzles 63 independently sprays water under the control of the control module. When it is detected that a bird stops in a certain area, the control module controls the nozzles 63 in the area to spray until the bird leaves the area. When it is detected that the bird droppings coverage in a certain area exceeds a preset value, the control module controls the nozzles 63 in the area to spray to flush the bird droppings in the area.

[0047] Specifically, the specific process of the navigation mark monitoring module in monitoring the bird droppings coverage in each area is as follows: according to the color difference between the gray-white bird droppings and the navigation mark (the surface of the navigation mark is mostly red, yellow and pure black), a suitable threshold is selected to divide the image into a droppings area and a non-drops area, and then the proportion of the number of pixels in the droppings area to the total number of pixels is counted as an indicator of the degree of droppings coverage, and the ratio of the area of ​​the droppings area to the fixed navigation mark area is calculated to obtain the degree of droppings coverage. Preferably, when the droppings coverage rate in the area reaches more than 50%, the water spraying module of the corresponding area is triggered to start. After every 1 minute of spraying, the nozzle 63 stops working, and the navigation mark monitoring module continues to monitor once. If it does not meet the standard, it continues to spray until the coverage rate drops below 20%. Among them, the above scheme will be adjusted according to the real-time monitoring data through the algorithm model of the central processing unit. If the expected cleaning effect is not achieved, the system will automatically adjust the spraying time.

[0048] It should be noted that when the navigation mark monitoring module detects that birds are staying in a certain area, the ultrasonic module will also start and play ultrasonic waves. In other words, as long as birds appear in the field of view of the intrusion monitoring module and the navigation mark monitoring module, the ultrasonic module will be started, and the water spray module will only be started when birds appear in the field of view of the navigation mark monitoring module and the bird droppings coverage rate exceeds the preset value. The two do not interfere with each other and can be carried out simultaneously. Example 2

[0049] Please refer to Figures 1 to 4 A navigation mark, which applies the bird-repelling system with self-cleaning function as described in Example 1, includes a float 1, a mounting frame 2 arranged on the float 1, and a monitoring device, an ultrasonic device 5, a water spraying device 6 and a control device 7 arranged on the mounting frame 2. The monitoring device is installed on the outside of the mounting frame 2, and is used to monitor and detect the buoy and the surrounding environment. The ultrasonic device 5 is installed in the mounting frame 2, and is used to emit ultrasonic waves to drive away birds. The water spraying device 6 includes a diversion mechanism 62, and a plurality of groups of nozzles 63 are installed on the diversion mechanism 62. The plurality of groups of nozzles 63 are respectively facing different directions on the top of the float 1. The control device 7 is respectively communicated with the ultrasonic device 5, the monitoring device and the water spraying device 6.

[0050] In this embodiment, the interior of the mounting frame 2 is hollow, the ultrasonic device 5 is installed on the top of the inner side of the mounting frame 2, the water spraying device 6 is located below the ultrasonic device 5, and the monitoring device is installed outside the mounting frame 2, wherein the monitoring device has two functions, one is to monitor birds, when the monitoring device finds that birds invade the vicinity of the navigation mark, the control device 7 controls the ultrasonic device 5 to start, and starts to emit ultrasonic waves to drive away the birds, when the monitoring device finds that birds are stationed on the floating body 1, the control device 7 controls the water spraying device 6 to start, so that the nozzle 63 starts to spray water to drive away the birds stationed on the floating body 1, and the second is to monitor bird droppings, the monitoring device can generate an image of the top of the floating body 1 and monitor it, and identify the bird droppings on the top of the floating body 1 in the image. The proportion and accumulation of bird droppings, when the bird droppings accumulate to a preset degree, the control device 7 controls the water spraying device 6 to start, and the nozzles 63 flush the top of the floating body 1 by spraying water to achieve the cleaning effect, so as to avoid the long-term accumulation of bird droppings and the corrosion of navigation facilities. Among them, the water spraying device 6 is provided with 4 groups of nozzles 63, and the 4 groups of nozzles 63 correspond to the top surface of the floating body 1 respectively, and are located in 4 areas in front, behind, left and right of the mounting frame 2 (because the mounting frame 2 is installed in the center of the floating body 1, the bird droppings will not fall on the position of the mounting frame 2, so the surface area of ​​the floating body 1 at the bottom of the mounting frame 2 does not need to be monitored), each group of nozzles 63 can spray water independently, so that under the control of the control device 7, water can be sprayed only on the areas where bird droppings exist and birds are stationed.

[0051] It is understandable that during the actual use of the beacon, bird droppings usually concentrate on the top of the float 1 of the beacon due to the large area of ​​the float 1. Therefore, in this embodiment, only four groups of nozzles 63 are arranged toward the top of the float 1 to flush the four areas of the top of the float 1 based on the front, back, left and right of the mounting frame 2 to ensure the cleanliness of the surface of the float 1. In addition, in some embodiments, some additional nozzles 63 may be arranged toward the surface of the mounting frame 2 to clean the bird droppings on the mounting frame 2.

[0052] It should be noted that the ultrasonic device 5 in this embodiment is a variable frequency ultrasonic generator, which emits variable frequency ultrasonic waves under the control of the control device 7 according to the ultrasonic wave band strategy for different types of birds in Example 1.

[0053] In this embodiment, an annular frame 3 is arranged around the outer side of the mounting frame 2, and bird-repelling spikes 31 are wound and installed on the annular frame 3. The bird-repelling spikes 31 are used to prevent birds from approaching and staying, so as to further enhance the bird-repelling effect.

[0054] In this embodiment, the monitoring device includes two groups of monitoring units, each group of monitoring units includes two cameras 4 arranged opposite to each other. In order to facilitate the adjustment of the field of view of the camera 4, the camera 4 is installed on the ring frame 3, and the angle between the two adjacent cameras 4 is the same, both of which are 90°. The camera 4 has a built-in image recognition program. One group of cameras 4 faces the top of the navigation mark (hereinafter referred to as Group A), which is used to monitor the invasion of birds above the navigation mark, and the other group of cameras 4 faces the lower floating body 1 (hereinafter referred to as Group B), which is used to monitor the invasion of birds in the surrounding area of ​​the navigation mark. Through the two groups of cameras, Group A and Group B, all-round monitoring of the navigation mark is achieved.

[0055] In addition, in addition to the function of monitoring bird invasion, the B group camera also has an image recognition function, that is, it recognizes and detects the birds and bird droppings on the floating body 1. When it is recognized that there are birds on the floating body 1 or the bird droppings cover reaches a preset degree, the water spray device 6 will be activated to wash the floating body 1. The above two functions can be performed simultaneously. For example, when a bird appears in the visual range of the A group or B group camera, the ultrasonic device 5 is activated until the bird disappears and stops. At the same time, if the B group camera finds that there are birds on the top of the floating body 1 or bird droppings accumulate on the top of the floating body 1 through image recognition, the water spray device 6 is turned on until the bird leaves or the bird droppings are cleaned, and the water spray device 6 stops. In other words, as long as there are birds in the visual range of the A group and the B group, the ultrasonic device 5 will be activated, and only when the B group camera detects that there are birds or bird droppings on the floating body 1, the water spray device 6 is activated. The above two situations are performed simultaneously and do not interfere with each other.

[0056] It should be noted that, in specific implementation, the number of cameras 4 in each group of monitoring units can be flexibly adjusted according to actual needs.

[0057] In this embodiment, the water spraying device 6 includes a water pump 61 and a diverter mechanism 62. The water pump 61 is located below the diverter mechanism 62 and is connected to the diverter mechanism 62 through a pipeline. The water pump 61 is provided with a pumping pipe 611. The water inlet end of the pumping pipe 611 is inserted into the water. The water pump 61 can directly pump water through the pumping pipe 611 and send the water into the diverter mechanism 62. Four groups of nozzles 63 are respectively arranged on the front, back, left and right sides of the diverter mechanism 62. The diverter mechanism 62 is used to divert the water sent by the water pump 61 to each nozzle 63 to perform water spraying.

[0058] It can be understood that in actual application, the diversion mechanism 62 is equipped with an electrically controlled valve, so that under the control of the control module, the nozzles 63 in the corresponding area are controlled to spray water according to the position of the birds on the float 1 and the distribution position of the bird droppings, thereby achieving targeted bird repelling and cleaning work.

[0059] In this embodiment, a control device 7 is provided inside the mounting frame 2, and the control device 7 is installed on the surface of the inner top of the mounting frame 2. Preferably, the control device 7 is a single-chip microcomputer, which is electrically connected to the ultrasonic device 5, the monitoring device and the water spraying device 6 to control the operation of each device to realize the automated processing of bird repelling and self-cleaning.

[0060] In this embodiment, a warning light 21 is installed on the top of the mounting frame 2, and the warning light 21 plays a role of warning and prompting by emitting light. Example

[0061] Please refer to Figure 4 In one embodiment of the present application, a navigation mark is provided. The structure and principle of this embodiment are basically the same as those of embodiment 2. The difference is that the monitoring device in this embodiment uses radar 8. Radar 8 can obtain the returned image by emitting electromagnetic waves, which is similar to the function of camera 4. In addition, in this embodiment, radar 8 is installed on the outer surface of the mounting frame 2.

[0062] Specifically, two groups of radars 8 are provided, each group includes two radars 8, wherein the mounting frame 2 is a quadrangular prism structure, and the two radars 8 of each group are respectively arranged on two opposite sides of the mounting frame 2, wherein one group of radars 8 has the same function as the group A camera 4 in Example 2, and the other group of radars 8 has the same function as the group B camera 4, which will not be elaborated herein.
