[0043] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0044] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an airport bird strike prevention detection and drive integrated system, including:

[0046] Bird detection equipment, used to monitor target objects in the airport bird strike responsibility area and the target space area above and around the airport, the target objects at least including birds;

[0047] a bird identification device connected to the bird detection device, and configured to obtain a first notification issued by the bird detection device when the bird detection device detects a candidate object suspected to be a bird, and collect video information of the candidate object based on the first notification, so as to identify the candidate object based on the collected video information and determine whether it is the target object;

[0048] a bird dispersing device connected to the bird detection device, configured to obtain a second notification issued by the bird detection device when the bird detection device detects the candidate object, and execute a dispersing strategy based on the second notification, wherein the dispersing strategy includes at least a dispersing method and a dispersing area;

[0049] The bird strike prevention information management platform is connected to the bird detection device, the bird identification device, and the bird dispersing device, so as to at least obtain and store the operation information of the bird detection device, the bird identification device, and the bird dispersing device, as well as obtain and store the monitoring information of the bird detection device, the video information collected by the bird identification device, and the uploaded identification results, and monitor and manage the bird detection device, the bird identification device, and the bird dispersing device based on the obtained information. The bird strike prevention information management platform can also respond to different viewing instructions to match and display different content.

[0050] Based on the above content, it can be known that the beneficial effects of this embodiment include that by setting up an integrated detection and driving system including bird detection equipment, bird identification equipment, bird dispersal equipment and a bird strike prevention information management platform, the bird situation prevention of the entire airport can be effectively managed and controlled. The integrated detection and driving system in this embodiment is not only a splicing between different detection equipment, or a simple splicing between detection and dispersal equipment, but a multi-integrated integration of a series of actions such as fully automated detection, monitoring, tracking, dispersal, and recording. Moreover, under the logic of comprehensive bird situation prevention management, it also includes its supporting overall business system, such as data analysis, equipment management, ecological operation management, operation records and other system modules involved in various aspects of the airport flight area management department, which truly changes from the traditional paper office mode to a digital, networked, and intelligent electronic management system, realizing effective management of airport bird situation and ensuring the safety of aircraft during takeoff and landing.

[0051] Furthermore, if Figure 3As shown, the bird detection equipment in this embodiment includes a phased array bird detection radar and a refrigerated weekly bird detection optoelectronic device, which is used to realize real-time, all-weather, high-precision, and automated detection and monitoring of birds within the airport's responsibility area. For bird detection equipment, multiple devices can be flexibly set according to the size of the detection area, and the specific number and setting location are not limited. Among them, the phased array bird detection radar is used to monitor the target object in the target space area. For example, the radar mainly covers a space area with a radius of 6km-8km and an altitude of more than 30m, etc., which can realize automatic detection and classification of targets such as birds, aircraft, and drones, and accurately obtain key information such as target position, altitude, speed, and heading. The refrigerated weekly bird detection optoelectronic device is used to monitor the target object in the airport bird strike responsibility area, such as the low-altitude area within the airport, including the 0-40 meter low-altitude area. In this embodiment, the cooling type scanning photoelectric device uses heat tracking technology to monitor birds, aircraft, drones, airborne objects and other flying objects in the airport bird strike responsibility area and the 0-40m space area in real time around the clock, and obtain key information such as the category, direction, distance, height, speed, slice, trajectory, etc. of the detected target. The above area is not fixed, for example, it can also be within 100 meters of the aircraft takeoff and within 60 meters of the approach, etc., and the specific area can be limited according to the actual situation of each airport.

[0052] Based on the composition of the bird detection equipment in the above embodiment, it can be known that the composition adopts a multi-technology fusion method, which can give full play to the advantages and characteristics of phased array radar, infrared optoelectronic technology and telephotoelectric technology. For example, in terms of bird detection radar, the advantages of phased array radar in wide area, high precision and all-weather can be fully utilized. Phased array radar has obvious advantages of detection accuracy and more accurate three-dimensional coordinate information than the original electron tube navigation radar (vertical + horizontal). At the same time, in terms of band selection, it can be but not limited to selecting X-band phased array radar, which can effectively detect bird targets farther and more stably all-weather, effectively avoiding the weak target reflection intensity, short distance, and stronger impact of adverse weather conditions caused by the atmospheric loss of electromagnetic waves caused by the short wavelength of Ku-band radar. In addition, some bands, such as S-band radar, can be avoided because of the long wavelength, the detection distance is not consistent with the airport detection scene, the volume and power consumption are too large, and the problem of causing a larger range of electromagnetic wave interference to the surrounding area can be avoided, while avoiding the waste of investment costs. Of course, the above-mentioned X-band is not a fixed choice. Radar equipment of other bands can also be selected, such as C-band radar equipment, etc. The specific selection can be flexibly made according to the actual situation.

[0053] In terms of the optoelectronic equipment for bird detection, this embodiment uses a refrigerated wide-area high-speed weekly scanning infrared optoelectronics, which can detect targets using infrared thermal imaging technology day and night, and obtain accurate information of all heat unit targets (birds, aircraft, drones, etc.) within the detection range. It effectively avoids the problem of insufficient detection capability of bird detection radar at low altitude (such as 0-30m regional spatial range) under ground clutter interference. At the same time, according to the characteristics of birds, a refrigerated weekly scanning is adopted, which has better thermal sensitivity, higher accuracy, smaller error, and wider detection temperature range when detecting targets, so that it can achieve more accurate detection accuracy, longer detection distance and higher resolution under more severe meteorological conditions, greatly improving the accuracy and detection efficiency of low-altitude area detection. The high-speed weekly scanning speed of 1s / circle multi-target all-round detection mode can realize real-time and accurate monitoring of the entire field in the low-altitude area. Compared with other step-type turntable optoelectronics, the refrigerated wide-area high-speed weekly scanning infrared optoelectronic equipment has obvious delay-free advantages, which effectively ensures the realization of all-weather real-time detection and drive linkage in low-altitude areas.

[0054] In one embodiment, the candidate objects described in this embodiment can be, for example, non-bird flying objects such as drones and balloons, or birds. When the bird detection device monitors the candidate objects, it will determine the spatial coordinates of the candidate objects and form a first notification based on the spatial coordinates; or when the bird detection device monitors the candidate objects, it will identify the appearance features and motion features of the candidate objects, such as contour coordinates, contour lines, uniform flight, stagnant state, etc., and determine the spatial coordinates of the candidate objects, and then form the first notification based on the recognition results and the spatial coordinates.

[0055] Furthermore, the bird recognition device is a dual-light turntable photoelectric device, and the airport of this embodiment is equipped with the bird recognition device in different areas. The bird recognition device realizes all-weather real-time tracking and image acquisition of various aerial targets detected by the front-end bird detection device. Each bird recognition device has its own shooting range, and the bird detection device knows the shooting range of each bird recognition device. Therefore, when a candidate object is found, the bird detection device determines the target bird recognition device based on the spatial coordinates and sends a first notification to the target bird recognition device. After the bird recognition device obtains the first notification, it adjusts the shooting orientation based on the spatial coordinates in the first notification, and then shoots the candidate object to obtain video information. In this embodiment, each of the bird recognition devices has a bird recognition model, and the bird recognition model is used to identify the candidate object according to the video information to determine whether the candidate object is a bird, as well as the name, image, and introduction information of the bird. If it is determined that the bird is a magpie, the image of the magpie and the habit information about the magpie will be automatically determined according to the pre-stored data.

[0056] The solution in this embodiment tracks and confirms high-risk targets and targets in highly sensitive areas by adopting dual-light turntable optoelectronic equipment, and multiple dual-light turntable optoelectronic equipment can be networked to realize camera relay tracking and aiming, and can preferentially track the aircraft's approach and departure path when the aircraft takes off and lands. The image information can be used as a verification of the authenticity and identity of aerial targets, and can be used as a basis for judging and analyzing the activity behavior of birds in a field and the playback and identification of bird strike incidents.

[0057] In actual application, the identification device in this embodiment specifically adopts a long-focus zoom dual-light turntable optoelectronic device. Under the guidance of phased array radar or refrigerated scanning optoelectronics, the device can quickly and high-definition observe and aim at aerial bird targets, and the retained image information can be used for accident judgment; bird photo slices can be used for bird species identification. This technical route has obvious multi-scene advantages over the multi-focus fixed-focus optoelectronics, that is, continuous tracking and imaging of aerial targets during the day and night can be achieved through continuous and smooth zooming, effectively avoiding the problems of short observation distance and jumping of observation images of multi-focus fixed-focus optoelectronics. Combined with the above technical characteristics, the long-focus zoom dual-light turntable optoelectronics deployed in the airport in this embodiment can also be used for multiple scenarios such as aircraft take-off and landing tracking observation, runway anti-intrusion tracking observation, and emergency rescue remote monitoring, achieving "multi-scene one machine reuse", while ensuring the bird target observation effect and greatly saving investment. Of course, corresponding to different airports, different situations, the type of dual-light turntable optoelectronic equipment used can also be different, that is, it is not limited to the long-focus type equipment in the above embodiment.

[0058] In another embodiment, the target space area includes a responsibility area and an early warning area, and the distance between the early warning area and the airport bird strike responsibility area is greater than the distance between the responsibility area and the airport bird strike responsibility area, such as the responsibility area is a space of 0-40m above the airport, and the early warning area is a space of 40m-50m, etc., or the responsibility area is a space of 0-100m above the airport, and the early warning area is a space of 100m-500m, etc., which can be flexibly determined according to actual conditions. When the bird situation detection device determines that the early warning area has a candidate object, it predicts the flight trend of the candidate object at the next moment. When the flight trend matches the target trend, it indicates that the candidate object is flying toward the early warning area, determines the spatial coordinates of the candidate object, and forms a second notification based on the spatial coordinates. If a flying bird flies parallel to the responsibility area, the flight trend does not match the target trend, and if the flying bird flies toward the responsibility area, the flight trend matches the target trend. At this time, the flying bird poses a threat to the responsibility area, so the detection device determines its spatial coordinates and forms a second notification. When the bird detection device detects a candidate object in the responsible area or the airport bird strike responsibility area, it will determine the spatial coordinates of the candidate object and form a second notification based on the spatial coordinates. The determined second notification will be sent by the detection device to the bird dispersal device so that it can perform a dispersal operation.

[0059] Continue to combine Figure 3 As shown, the bird dispersing device in this embodiment includes at least one of the following:

[0060] Omnidirectional sonic bird repellent equipment, directional sonic bird repellent equipment;

[0061] All of the above-mentioned equipment have the characteristics of high sound pressure intensity, rich sound source changes and high response efficiency.

[0062] Among them, Figure 3 , Figure 4 and Figure 5 As shown in the figure, the omnidirectional sonic bird repellent equipment is mainly arranged parallel to the runway on both sides of the runway (corresponding to the hemispherical sonic area in the figure), which effectively prevents birds from staying in the soil area of ​​the lift belt and forms a sound barrier around the runway pavement. The equipped ultrasonic transducer can effectively disperse special animals such as swallows and bats.

[0063] Continue to combine Figure 3 As shown, the directional sound wave bird-repelling equipment (corresponding to the fan-shaped sound wave area in the figure) is arranged at both ends of the runway. According to different functions, it can respectively take on the role of taking off, approach route and descent, and disperse the concentrated strong sound in the heading sensitive area.

[0064] Through the reasonable and efficient layout of the above-mentioned dispersal equipment throughout the field, a bird invasion protection barrier is constructed for the high-speed operation area of ​​aircraft that combines high and low, far and near. Based on this, the bird detection equipment can automatically start the bird repellent equipment by feeding back the detection results to the bird repellent equipment in real time in the form of a second notification, thereby realizing effective bird repellent operation and achieving significant bird repellent effect.

[0065] Furthermore, when the bird detection device detects a candidate object, it determines the spatial coordinates of the candidate object, and determines the area where the candidate object is located based on the spatial coordinates, and then forms a second notification based on at least the spatial coordinates, and sends the second notification to the bird dispersing device corresponding to the area, and the area includes at least one bird dispersing device;

[0066] In response to the second notification, the bird dispersing device determines a target dispersing area based on the spatial coordinates, where the target dispersing area is the smallest area that includes the candidate object. The bird dispersing device determines whether its own dispersing range includes the target dispersing area. If so, the dispersing method is determined based on the position of the target dispersing area. If the bird dispersing device supports the dispersing method, the device itself is determined to be the target dispersing device.

[0067] For example, if the candidate object is located on the airport runway, the refrigerated scanning photoelectric device will send a second notification to some or all of the omnidirectional sound wave bird repellent devices, so that all bird repellent devices located on the airport runway will respond to the second notification and send out omnidirectional sound waves to disperse the birds in the area. Alternatively, the bird repellent devices in the area adjacent to the location of the candidate object may send out omnidirectional sound waves, or the bird repellent devices in multiple areas along the length of the runway may send out omnidirectional sound waves in sequence to achieve continuous dispersal of the candidate object and keep it away from the runway. When the candidate object is located in the aircraft take-off and landing area above the airport, the bird detection radar device will notify the corresponding bird repellent device when it detects the candidate object, that is, send a second notification to the bird repellent device that can output directional sound waves within the area where the current candidate object is located, so that it responds to the second notification and sends out directional sound waves to the area where the candidate object is located. In addition, the bird repellent device can also send out directional sound waves to the candidate object in a tracking manner to a certain extent to effectively disperse it. For example, a bird detection device predicts the flight trend of a candidate object, and based on the prediction result and the current spatial coordinates, tracks and disperses the candidate object within a certain range; or multiple bird dispersing devices share the prediction result and cooperate to achieve tracking and dispersing of the candidate object; or each dispersing device determines the flight habits of birds based on historical data, and is equipped with the ability to rotate within a certain angle range, so that it automatically rotates within a preset angle range with the spatial coordinates as the starting point to emit directional sound waves to disperse the birds.

[0068] Furthermore, the bird strike prevention information management platform in this embodiment is composed of the bird prevention system software and the centralized monitoring command center. The system includes a computer client and a tablet mobile client. The system software mainly realizes the real-time presentation, image review, observation and aiming linkage and risk alarm of the automatic bird detection data around the clock, and can grasp the location, height, number, type, range, danger level and activity pattern of birds in the airport flight area in real time. Specifically, the bird strike prevention information management platform supports at least one of the following display modes:

[0069] The obtained video information is displayed at different viewing angles, the video information of different time periods is displayed based on different display effects, the recognition results are displayed, the statistical information of different types of monitoring results of birds in the target time period is displayed, the status of the currently monitored candidate objects in the airport bird strike responsibility area or the target space area is dynamically displayed in the form of a heat map, the obtained video information is displayed in a multi-virtual screen format, and each virtual screen corresponds to a viewing angle, the operating parameters of each device and the actual posture of the corresponding simulation object are displayed, the flight information of the target time period is displayed, and the parameter configuration interface of each device is displayed, so that the user can personalize the operating parameters of each device based on the parameter configuration interface, and the personalized configuration includes the configuration of the operating time period, and the operating time period is related to the flight time of the aircraft in the airport.

[0070] In addition, the platform system in this embodiment can also support users to set bird prevention areas with different alert levels according to the spatial height and horizontal range of the airport flight area, that is, the target space area and the airport bird strike responsibility area can support flexible settings, and the platform system also supports real-time presentation of the spatial relationship of detected birds and aircraft in the airport airspace. In addition, the system can also activate the bird-repelling equipment in the corresponding area to drive away the birds according to the detection results of the bird detection equipment, that is, the system has control authority over the bird-repelling equipment, can issue instructions to it, and realize control, but this situation is usually used when the bird-repelling equipment does not respond to the second notification issued by the detection equipment in time, or the bird-repelling effect is always not up to standard, so an alarm is issued to notify the staff to intervene manually to achieve bird repelling.

[0071] Furthermore, the bird strike prevention information management platform in this embodiment can also realize comprehensive monitoring of bird repellent equipment in the field, and view the deployment location, coverage, operation status (such as determining whether the operation status of the equipment is normal / abnormal) and mode effect of the bird repellent equipment in real time, as well as the custom setting of the use strategy of the bird repellent equipment, the arrangement of bird repellent equipment maintenance tasks, the statistics of faulty equipment and maintenance conditions, and the automatic evaluation of the effectiveness monitoring of the bird repellent equipment. It can also carry out information management of comprehensive management matters such as daily scheduling and training of the bird prevention department. Moreover, the system can save weekly, monthly, and grade-level bird activity data, support event review, data statistical analysis, and the presentation of bird distribution heat maps, and can generate daily, weekly, monthly, and annual monitoring reports. The reports include the threat level of bird species, the time, location, and number of bird species activities, as well as the bird species and areas that need to be focused on. It can realize manual input of manually detected bird data, bird strike data, etc., and realize bird statistics, intelligent analysis, data fusion reports, etc. The system supports access to GIS data, which can display and locate the equipment in real time on the map. The map can be zoomed in, out and rotated at will. It also supports access to external ADS-B data, and can automatically start the control plan of related bird-repelling equipment in advance according to aircraft information. The bird prevention and management command room is equipped with system platform servers, bird identification servers, radar data fusion servers, bird information storage servers, splicing large screens and other equipment, and has a centralized bird monitoring seat, which can monitor the airport bird situation in all aspects, in real time and around the clock. At the same time, the system is equipped with multiple mobile terminals PAD, which is convenient for on-site patrol personnel to obtain bird information in real time and remotely control and call bird-repelling equipment. At the same time, the terminal also has the function of ecological information research.

[0072] In another embodiment, when the identification device fails to identify, the bird strike prevention information management platform can also search for the bird name, image, and introduction information corresponding to the candidate object in a local database or a network database based on the obtained video information, and feed the search result back to the bird identification device so that the bird identification device can learn;

[0073] The bird strike prevention information management platform can also analyze and determine the causes of bird stay and corresponding solutions based on the identification results of birds within the target time period and the stay area within the airport bird strike responsibility area, and feedback the causes and solutions to the user end for user reference.

[0074] For example, through the bird recognition results and spatial coordinates within a period of time, the system can determine the location of the birds in the airport during that period of time. Based on the location and the pre-stored full-range information in the airport, the system can analyze and determine which areas of the airport the birds stay in, such as green belt areas, passenger or airport staff residence areas, etc. If it is a green belt area, it can be explained that the green belt attracts a certain type or multiple types of birds, and the staff needs to be prompted to intervene accordingly. If it is a personnel residence area, it can be explained that there may be personnel intentionally feeding in the area, or there are environmental hygiene phenomena that trigger birds to forage, so birds stay. At this time, the staff also needs to be prompted to intervene accordingly.

[0075] When the integrated system constructed in this embodiment is put into practical application, it can also support the targeted introduction of multi-scene confirmation, multi-data compounding and multi-device linkage functions for the complex detection environment in the airspace of the airport, so that the identity of the flying target can be confirmed by at least two or more detection devices. Under the large-scale detection of the radar (such as in the airspace above 30m in height), the initial category of the detected target is classified, and the category, size, flight speed, flight altitude and degree of danger of the target are statistically analyzed. When the target enters the photoelectric weekly scanning monitoring area (such as the area with a height of 0-40m), the weekly scanning photoelectric will conduct a panoramic monitoring of the detection range and record the flight trajectory of the bird. Once the bird flies to a sensitive area or is a high-risk bird species, the radar or weekly scanning photoelectric will promptly issue instructions to the dual-light turntable photoelectric of the bird identification system, track it, and lock and confirm the identity of the target. At the same time, the dual-light turntable photoelectric equipment can perform relay tracking to ensure that the flight trajectory of the high-risk target is clearly recorded. The scenario is different from the traditional airspace detection. Our field has further iterated the detection, monitoring and tracking scenarios. In addition to recording the flight trajectory in the airspace, the algorithm can also supplement the flight trajectory of birds flying through trees and buildings to a certain degree of continuity. Even birds that fall into the grass on the ground can be effectively monitored.

[0076] Moreover, the system as a whole can be configured to be compatible with the protocols and ports used by most current products, which can effectively cope with the expansion requirements of the future system. At the same time, in terms of the original equipment of the airport, it has the ability to link the network, support the access of each device to the system for unified management and operation, and transform the bird-repelling operation from the traditional consumption of human resources outside the field to an efficient one-click management mode indoors.

[0077] The three-area-in-one mode used by the integrated detection and driving system in this embodiment effectively evaluates the risk factor of the target object by effectively dividing and managing the airport area, so as to transform the original mechanical means of driving away birds into a more intelligent precise tracking and precise dispersal of high-risk targets. In actual situations, due to the ecological environment of the airport, bird activities around the airport are relatively frequent. If all active birds are tracked or dispersed, a lot of time and energy consumption will be dispersed to deal with low-risk targets. These low-risk target active birds trigger bird-repelling equipment and occupy detection resources for a long time, which not only greatly reduces the dispersal effect of bird-repelling equipment, but also covers up the pertinence and outstanding problems of the data analysis report, so that the report cannot effectively reflect the key areas and birds to be prevented. The integrated detection and fun system proposed in this embodiment can allocate different detection modes to birds in different areas by zoning the airport, and exert the functions of the dispersal equipment and bird tracking and identification system in the core security area, so as to accurately disperse and identify bird species that cause high-risk activities, and effectively verify the dispersal effect and adjust the strategy in time. Thereby improving the pertinence and scientificity of bird-repelling efficiency, and further solving the noise problem in environmental protection. For ecological protection areas such as green belts at airports, corresponding airport ecological monitoring devices can be used to monitor and record the food chain and important influencing factors of birds, obtain data on insect conditions, grass conditions, weather, etc., and promptly handle the habitats and nests of birds in and around the airport. In-depth research on the ecological environment of food sources in the airport and surrounding habitats can be carried out to effectively cut off the source of attracting birds to forage, establish big data analysis of the airport ecological chain, master the laws of elements, start from the source of the ecological chain, and reduce the occurrence of bird strikes.

The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
