Description

Technical Field

[0001] The present invention belongs to the technical field of safe operation of power systems, and in particular relates to a system and method for evaluating and controlling bird damage in power systems. Background Art

[0002] The safety of power transmission lines is crucial to national security, economic development, and social stability. However, bird control has long been a recognized challenge for transmission line operators. With the continued improvement of the ecological environment, bird populations have increased significantly, and their habitats and activity areas have expanded, posing a growing threat to the safe operation of power systems. Currently, bird damage has become one of the three major causes of transmission line failures. Every year, major power companies devote significant time and effort to addressing the damage posed by birds to transmission lines. Therefore, bird damage prevention and control efforts are crucial to the safe operation of power systems.

[0003] Currently, bird control measures, both domestically and internationally, primarily target the problem of bird activity causing line tripping. These measures employ methods such as repelling, scaring, and shielding to prevent line failures caused by bird activity. Practice has shown that birds are highly adaptable, making rigid and mechanical control devices ineffective in the long term. Once adapted, birds may even wrap weeds around the repellent equipment, further stabilizing their nests. Some devices, such as bird thorns, can deform or break, rendering them ineffective and potentially counterproductive, threatening the safe operation of power systems. Furthermore, a lack of detailed understanding of the characteristics of bird behavior and damage has resulted in limited targeted bird control measures. Most bird repellents operate in isolation, with no way to remotely control their strategies, establish coordinated repelling strategies, or evaluate their effectiveness.

[0004] In summary, there is an urgent need for a bird damage intelligent detection, expulsion and assessment system and method that can effectively reduce bird adaptability. Summary of the Invention

[0005] The present invention addresses the problems of the current bird-repelling system, which has a single function, a rigid detection and repelling process, cannot independently analyze bird conditions and evaluate the repelling effect, and does not have real-time linkage characteristics. There is no connection between the bird-repelling device and the background monitoring system, and it is impossible to obtain bird information and update the bird-repelling strategy in a targeted manner. The present invention provides a system and method for bird damage assessment and control in power systems.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A system for bird damage assessment and control in power systems, comprising several decentralized intelligent bird repellent systems and a central control host, wherein the intelligent bird repellent system adopts a 1+N structure, with 1 being a main device and N being sub-devices;

[0009] The sub-device includes a sub-device power module, a sub-device short-range communication module, a sub-device detection module, and a sub-device repelling module. The sub-device repelling module includes one or more of a sub-device ultrasonic repelling module, a sub-device strong light repelling module, and a sub-device sound repelling module. The sub-device power module is used to power the sub-device. The sub-device detection module is used to detect the movement of approaching birds and transmit the detection information to the main device via the sub-device short-range communication module. The sub-device repelling module is used to repel birds and receives instructions from the main device processing module via the sub-device short-range communication module to operate.

[0010] The central control host performs bird damage assessment, secondary bird repellent video assessment, repellent strategy replacement and upgrade, and regional linkage repellent according to the information uploaded by the main device;

[0011] The specific installation positions and numbers of the main device and sub-devices are determined according to the spatial structure of the target area, taking into account the detection range of each device's detection module and the range of action of each device's sound repelling module, each device's strong light repelling module, and each device's ultrasonic repelling module, so as to achieve complementary coverage of each device's detection module, reasonable matching of each device's repelling module, and complementary coverage.

[0012] A further improvement of the present invention is that the repelling strategy specifically refers to the working mode of the main device repelling module and the sub-device repelling module, including: the light source intensity, light source flashing mode and frequency, and strong light start and stop conditions of the main device strong light repelling module and the sub-device strong light repelling module when working; the bird repelling sound set, sound decibel level, and sound start and stop conditions played by the main device sound repelling module and the sub-device sound repelling module when working; the ultrasonic frequency and ultrasonic start and stop conditions emitted by the main device ultrasonic repelling module and the sub-device ultrasonic repelling module when working; the strong light start and stop conditions, sound start and stop conditions, and ultrasonic start and stop conditions are designed according to the spatial location and existence time of the approaching birds, so as to achieve coordination and cooperation of various bird repelling methods;

[0013] The main device processing module pre-stores multiple sets of repelling strategies, specifically referring to the main device processing module storing multiple sets of working modes of the main device repelling module and the sub-device repelling module, these working modes are independent of each other and different from each other, and a certain sequence is followed when switching the repelling strategy; when performing bird repelling work, the main device processing module sends instructions according to the working modes designed for each module in the current repelling strategy to control the main device repelling module and the sub-device repelling module to perform bird repelling.

[0014] A further improvement of the present invention is that the main device power supply module and the sub-device power supply module are powered by a solar unit or a mutual induction power supply unit; the main device remote communication module uses a 4G / 5G communication unit to communicate with the central control host; the main device positioning module uses a GPS unit for positioning; the main device short-range communication module and the sub-device short-range communication module use a BLE low-power Bluetooth unit to complete the communication between the main device and the sub-device; the main device video module uses a high-definition camera or an infrared camera for shooting; the main device detection module and the sub-device detection module use a Doppler radar unit or an infrared sensing unit for bird motion detection; the main device strong light drive away module and the sub-device strong light drive away module use a laser generator or an LED strong light source unit.

[0015] The method for systematic bird damage assessment and control for power system bird damage assessment and control comprises the following specific steps:

[0016] Step 1: The intelligent bird repellent system uses the main device detection module and the sub-device detection module to monitor the target airspace in real time and obtain bird activity information. The sub-device transmits the detected bird activity information to the main device. The main device processing module conducts a comprehensive analysis of the bird activity information obtained by the main device detection module and the sub-device detection module to obtain accurate bird spatial information;

[0017] Step 2: The main device processing module pre-stores multiple sets of repelling strategies. If the result of step 1 is that there are bird activities in the target airspace, the main device processing module controls the main device repelling module and the sub-device repelling module to carry out joint bird repelling according to the current repelling strategy. During the bird repelling process, the main device processing module evaluates the bird repelling effect and switches the repelling strategy of the smart bird repelling system in time according to the repelling effect.

[0018] Step 3: If the main device processing module comprehensively determines in step 1 that there is bird activity in the target airspace, the main device video module is activated, and the main device uploads the video of the bird repelling process to the central control host. The central control host performs image analysis of the bird repelling process in the video, completes a secondary evaluation of the bird repelling effect video, and determines whether the repelling is successful;

[0019] Step 4: Combine the primary evaluation result of the bird repellent effect of the main device processing module in step 2 and the secondary evaluation result of the bird repellent effect video of the central control host in step 3 to obtain a comprehensive bird repellent evaluation result, and obtain the comprehensive repellent success rate of each bird repellent strategy pre-stored in the main device processing module over a period of time. If the comprehensive repellent success rate corresponding to each repellent strategy is lower than the threshold, the central control host performs a remote autonomous upgrade and improves and replaces all the repellent strategies pre-stored in the main device processing module;

[0020] Step 5: The main device processing module periodically sends an open command to the main device video module to obtain images of the target area and upload them to the central control host. The central control host completes the identification of bird nests in the target area and, combined with the image analysis of the bird expulsion process in the video performed by the central control host in step 3, assesses the severity of bird damage in the target area.

[0021] Step 6: After the main device processing module comprehensively determines that there is bird activity in the target airspace, it uploads the detection information to the central control host. The central control host controls the adjacent smart bird-repellent systems to perform regional linkage bird-repellent according to the geographical location of the smart bird-repellent system to which the main device belongs.

[0022] A further improvement of the present invention is that the bird-repelling link in step 2 specifically comprises the following steps:

[0023] Step 2.1: If the main device processing module analyzes that there is bird activity in the target area, the main device processing module sends instructions according to the working mode designed by each module in the current repelling strategy to control the main device repelling module and the sub-device repelling module to perform bird repelling;

[0024] Step 2.2: After the repelling starts in step 2.1, the main device processing module performs a first evaluation of the bird repelling effect. If the duration of the detected bird in the target airspace is greater than the threshold or the duration of the bird being detected in the target airspace for two consecutive times is less than the threshold, the result of the first evaluation of the bird repelling effect is that the bird repelling has failed.

[0025] Step 2.3: The main device processing module pre-stores multiple sets of repelling strategies; if the main device processing module's bird repelling effect evaluation result in step 2.2 is a failure, the main device processing module immediately switches to another pre-stored set of repelling strategies in sequence; if the main device processing module's bird repelling effect evaluation result in step 2.2 is a success, the current repelling strategy remains unchanged; the sequence is a cyclic sequence, and after switching to the last set of repelling strategies, it returns to the first set of repelling strategies pre-stored in the main device processing module.

[0026] A further improvement of the present invention is that the video evaluation process in step 3 specifically includes the following steps:

[0027] Step 3.1: If the main device processing module's comprehensive judgment result shows that there is bird activity in the target area, a command is sent to turn on the main device's video module to shoot the target area and upload it to the central control host;

[0028] Step 3.2: The central control host uses image recognition technology to identify bird species, bird numbers, and activity trajectories. If any bird's activity trajectory gets too close to or even stops at a critical area of power equipment, the bird repellent operation is deemed a failure. The identified bird species, bird numbers, and activity trajectory information provide a reference for autonomous upgrades and replacements of the repellent strategy.

[0029] A further improvement of the present invention is that the autonomous upgrade and replacement process of the expulsion strategy in step 4 specifically includes the following steps:

[0030] Step 4.1: The central control host collects long-term statistics on the primary evaluation results of the bird repellent effect of the main device processing module in step 2 and the secondary evaluation results of the bird repellent effect video of the central control host in step 3. The two evaluation results are combined to obtain a comprehensive bird repellent evaluation result for each bird repellent. If one of the two bird repellent evaluation results is judged as a failure, the repellent is judged as a failure; this result corresponds to the repellent strategy at that time.

[0031] Step 4.2: For the multiple sets of repelling strategies pre-stored in the main device processing module, the central control host calculates the repelling success rate of each repelling strategy over a period of time. If the bird repelling success rate corresponding to all the repelling strategies pre-stored in the main device processing module is less than a threshold, the central control host replaces each repelling strategy pre-stored in the main device processing module with the corresponding improved repelling strategy through the main device remote communication module to complete the autonomous upgrade; the improved repelling strategy is designed based on the bird species, bird population and activity trajectory information, and the improvements include: the light source intensity, light source flashing mode and frequency, and strong light start and stop conditions of the main device strong light repelling module and the sub-device strong light repelling module when working; the bird repelling sound set, sound decibel level, and sound start and stop conditions played by the main device sound repelling module and the sub-device sound repelling module when working; and the ultrasonic frequency and ultrasonic start and stop conditions emitted by the main device ultrasonic repelling module and the sub-device ultrasonic repelling module when working.

[0032] A further improvement of the present invention is that the bird damage severity assessment process in step 5 specifically comprises the following steps:

[0033] Step 5.1: The main device processing module periodically activates the main device video module to capture the target area and upload the captured images to the central control host;

[0034] Step 5.2: The central control host uses image recognition technology to identify bird nests in the target area. Based on the identification results and the bird activity trajectories obtained through image recognition technology, the host conducts bird damage analysis and classifies the bird damage level. If the damage is severe, human intervention is required. The bird damage level classification is shown in the table below:

[0035]

[0036]

[0037] A further improvement of the present invention is that the regional linkage bird-repelling process in step 6 specifically includes the following steps:

[0038] Step 6.1: If the analysis result of a main device processing module shows that there is bird activity in the target area of the smart bird repellent system, the detection information will be uploaded to the central control host;

[0039] Step 6.2: The central control host searches for any intelligent bird-repellent system within the vicinity of the intelligent bird-repellent system that has detected the bird, and checks whether there is any intelligent bird-repellent system whose distance from the intelligent bird-repellent system is less than a threshold. If there is one, the central control host turns on the strong light bird-repellent module in each device of the intelligent bird-repellent system that meets the distance condition and points it toward the intelligent bird-repellent system that has detected the bird, thereby performing regional collaborative bird-repellent. Compared with the prior art, the present invention has the following advantages:

[0040] The system of the present invention conducts bird reconnaissance through multi-module linkage. When birds are detected approaching, it uses multi-module and multi-repelling methods to achieve timely expulsion of birds. At the same time, the device can independently evaluate the effect of bird repelling and change the repelling strategy in time according to the repelling effect.

[0041] Existing bird repellent systems are mechanical and rigid, using a single device and a single repelling method, resulting in a small detection coverage and poor repelling effectiveness. This invention, based on a multi-module, linked intelligent bird pest detection and repelling system, integrates information from the system's main modules and sub-devices to achieve long-range, large-scale, and highly accurate bird detection. It also utilizes a repelling strategy that coordinates multiple repelling methods to achieve coordinated repelling. Once a bird infestation is detected, intelligent bird repellent systems in adjacent areas collaborate to achieve regionally linked repelling.

[0042] In existing bird-repelling systems, each device is relatively isolated from the others, making it impossible to integrate bird information and bird damage information, evaluate the bird-repelling effect of the device, independently upgrade the bird-repelling strategy based on the bird-repelling success rate, or conduct regional linkage bird-repelling. This makes the entire bird-repelling system lack the ability to cope with environmental changes and cannot solve the problem of reduced bird-repelling effect after birds adapt to existing bird-repelling methods. The main device processing module of the present invention pre-stores multiple sets of repelling strategies. The main device processing module switches the bird-repelling strategy in a timely manner based on the real-time bird-repelling effect of the device. After detecting the approach of birds, the main device processing module uploads the repelling video, completes the bird information recognition based on image recognition technology, and performs a secondary evaluation of the video bird-repelling effect. The comprehensive bird-repelling success rate is obtained by combining the two evaluation results, and the pre-stored repelling strategies of the device are upgraded and replaced as a whole. Based on regular video acquisition, bird nest identification is completed, and bird damage classification is completed in combination with video evaluation.

[0043] The system and method of the present invention can significantly reduce the adaptability of birds, grasp the activity patterns of regional birds, and improve the operational safety of the power system. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] See also Figure 1 A central control host connects multiple areas, each of which is composed of multiple sets of smart bird-repellent systems. The system installation locations include but are not limited to transmission lines, substations, railway power equipment, etc. The main device of each smart bird-repellent system communicates with the central control host, which obtains data from each main device and gives instructions.

[0051] See also Figure 2 In the embodiment of the present invention, the bird damage assessment and control system is composed of an intelligent bird-repelling system and a central control host, wherein the intelligent bird-repelling system adopts a 1+N structure, 1 is a main device and N is a sub-device;

[0052] The main device includes a main device processing module, a main device power module, a main device positioning module, a main device remote communication module, a main device short-range communication module, a main device detection module, a main device video module and a main device driving away module.

[0053] The sub-device includes a sub-device power module, a sub-device short-range communication module, a sub-device detection module, and a sub-device repelling module. The sub-device repelling module includes one or more of a sub-device ultrasonic repelling module, a sub-device strong light repelling module, and a sub-device sound repelling module. The sub-device power module is used to power the sub-device. The sub-device detection module is used to detect the movement of approaching birds and transmit the detection information to the main device via the sub-device short-range communication module. The sub-device repelling module is used to repel birds and receives instructions from the main device processing module via the sub-device short-range communication module to operate.

[0054] The central control host performs bird damage assessment, secondary bird repelling effect video assessment, repelling strategy replacement and upgrade, and regional linkage repelling based on the information uploaded by the main device.

[0055] As a preferred embodiment, the main device power supply module and the sub-device power supply module can use a solar unit or a mutual induction power supply unit to power the device; the main device remote communication module can use a 4G / 5G communication unit to communicate with the central control host; the main device positioning module can use a GPS unit for positioning; the main device short-range communication module and the sub-device short-range communication module can use a BLE low-power Bluetooth unit to complete the communication between the main device and the sub-device; the main device video module can use a high-definition camera or an infrared camera for shooting; the main device detection module and the sub-device detection module can use a Doppler radar unit or an infrared sensing unit for bird motion detection; the main device strong light drive away module and the sub-device strong light drive away module can use a laser generator or an LED strong light source unit.

[0056] See also Figure 3 In the embodiment of the present invention, the specific installation location and number of the main device and sub-devices are determined according to the spatial structure of the target area, taking into account the detection range of each device's detection module and the range of action of each device's sound expulsion module, each device's strong light expulsion module, and each device's ultrasonic expulsion module, so as to achieve complementary coverage of each device's detection module, reasonable matching of each device's expulsion module, and complementary coverage. Figure 3 As shown, in the transmission tower bird repellent scenario, the main device is equipped with a main device strong light repellent module and a main device laser repellent module, and the No. 3 sub-device is equipped with a sub-device strong light repellent module and a sub-device laser repellent module. The main device and sub-devices are respectively placed on the transmission line on both sides of the tower; the No. 1 sub-device and the No. 2 sub-device are equipped with a sub-device strong light repellent module, a sub-device sound repellent module, and a sub-device ultrasonic repellent module, both of which are placed at appropriate locations on the tower. The main device located on the line has a wider field of view and can use the main device video module to complete the coverage of the tower airspace. Bird detection can be completed on both the line and the tower, which can greatly increase the device's detection range and more accurately locate the approaching position of birds. The coverage range and angle of sound and strong light repellent are longer. The sub-device on the tower is equipped with a sub-device ultrasonic repellent module, which can perform short-distance, high-intensity repellent in areas where birds are prone to nesting and staying on the tower.

[0057] In an embodiment of the present invention, the expulsion strategy specifically refers to the working mode of the main device expulsion module and the sub-device expulsion module, including: the light source intensity, light source flashing mode and frequency, and strong light start and stop conditions of the main device strong light expulsion module and the sub-device strong light expulsion module when they are working; the bird-repelling sound set, sound decibel level, and sound start and stop conditions played by the main device sound expulsion module and the sub-device sound expulsion module when they are working; the ultrasonic frequency and ultrasonic start and stop conditions emitted by the main device ultrasonic expulsion module and the sub-device ultrasonic expulsion module when they are working; the strong light start and stop conditions, sound start and stop conditions, and ultrasonic start and stop conditions are designed according to the spatial position and existence time of the approaching birds to achieve coordination and cooperation of various bird-repelling methods.

[0058] like Figure 3 As shown, in the tower bird-repelling scenario, birds approach the tower from far away. When they enter the range of the strong light repelling module of each device, strong light repelling is activated. When they enter the range of the sound repelling module of each device, sound repelling is activated. When they enter the range of the ultrasonic repelling module of each device, ultrasonic repelling is activated. The bird repelling modules of each device are activated in sequence according to the spatial distance of the bird. When a single repelling method can complete the bird repelling work, the power consumption of the entire system can be reduced. When the bird repelling effect is not good, the activation conditions can also be changed to reduce the adaptability of the bird. The main device processing module pre-stores multiple sets of repelling strategies, specifically multiple sets of working modes of the main device repelling module and the sub-device repelling module. These working modes are independent and different from each other. When switching repelling strategies, a certain order is followed. When performing bird repelling, the main device processing module sends instructions according to the working modes designed for each module in the current repelling strategy to control the main device repelling module and the sub-device repelling module to repel the bird.

[0059] See also Figure 4 The bird damage assessment and control method in the embodiment of the present invention has the following specific steps:

[0060] Step 1: The intelligent bird repellent system uses the main device detection module and the sub-device detection module to monitor the target airspace in real time and obtain bird activity information. The sub-device transmits the detected bird activity information to the main device. The main device processing module conducts a comprehensive analysis of the bird activity information obtained by the main device detection module and the sub-device detection module to obtain accurate bird spatial information;

[0061] Step 2: The main device processing module pre-stores multiple sets of repelling strategies. If the result of step 1 is that there are bird activities in the target airspace, the main device processing module controls the main device repelling module and the sub-device repelling module to carry out joint bird repelling according to the current repelling strategy. During the bird repelling process, the main device processing module evaluates the bird repelling effect and switches the repelling strategy of the smart bird repelling system in time according to the repelling effect.

[0062] Step 3: If the main device processing module comprehensively determines in step 1 that there is bird activity in the target airspace, the main device video module is activated, and the main device uploads the video of the bird repelling process to the central control host. The central control host performs image analysis of the bird repelling process in the video, completes a secondary evaluation of the bird repelling effect video, and determines whether the repelling is successful;

[0063] Step 4: Combine the primary evaluation result of the bird repellent effect of the main device processing module in step 2 and the secondary evaluation result of the bird repellent effect video of the central control host in step 3 to obtain a comprehensive bird repellent evaluation result, and obtain the comprehensive repellent success rate of each bird repellent strategy pre-stored in the main device processing module over a period of time. If the comprehensive repellent success rate corresponding to each repellent strategy is lower than the threshold, the central control host performs a remote autonomous upgrade and improves and replaces all the repellent strategies pre-stored in the main device processing module;

[0064] Step 5: The main device processing module periodically sends an open command to the main device video module to obtain images of the target area and upload them to the central control host. The central control host completes the identification of bird nests in the target area and, combined with the image analysis of the bird expulsion process in the video performed by the central control host in step 3, assesses the severity of bird damage in the target area.

[0065] Step 6: After the main device processing module comprehensively determines that there is bird activity in the target airspace, it uploads the detection information to the central control host. The central control host controls the adjacent smart bird-repellent systems to perform regional linkage bird-repellent according to the geographical location of the smart bird-repellent system to which the main device belongs.

[0066] In the embodiment of the present invention, the module linkage intelligent expulsion link in step 2 specifically includes the following steps:

[0067] Step 2.1: If the main device processing module analyzes that there is bird activity in the target area, the main device processing module sends instructions according to the working mode designed by each module in the current repelling strategy to control the main device repelling module and the sub-device repelling module to perform bird repelling;

[0068] Step 2.2: After the repelling starts in step 2.1, the main device processing module performs a first evaluation of the bird repelling effect. If the duration of the detected bird in the target airspace is greater than the threshold or the duration of the bird being detected in the target airspace for two consecutive times is less than the threshold, the result of the first evaluation of the bird repelling effect is that the bird repelling has failed.

[0069] Step 2.3: The main device processing module pre-stores multiple sets of repelling strategies; if the main device processing module's bird repelling effect evaluation result in step 2.2 is a failure, the main device processing module immediately switches to another pre-stored set of repelling strategies in sequence; if the main device processing module's bird repelling effect evaluation result in step 2.2 is a success, the current repelling strategy remains unchanged; the sequence is a cyclic sequence, and after switching to the last set of repelling strategies, it returns to the first set of repelling strategies pre-stored in the main device processing module.

[0070] By using the detection modules of each device to determine whether there are birds in the detection range, whether the birds have been driven away, and the distance and direction of the birds, frequent and blind activation of the repelling modules of each device can be effectively avoided; the processing module of the main device can detect the bird repelling effect in real time, so that feedback can be promptly applied to the repelling strategy, and continuous poor bird repelling effect will not be caused; the processing module of the main device pre-stores multiple sets of repelling strategies, and can switch the repelling strategy in time when the repelling effect is poor. It has the ability to respond in time, making the bird repelling work more efficient, but the repelling strategy should not be switched if the repelling effect does not reach the threshold. Too frequent changes will also cause birds to adapt to all the repelling strategies in the device in advance, resulting in premature triggering of autonomous upgrades and replacements;

[0071] In the embodiment of the present invention, the video evaluation process in step 3 specifically includes the following steps:

[0072] Step 3.1: If the main device processing module's comprehensive judgment result shows that there is bird activity in the target area, a command is sent to turn on the main device's video module to shoot the target area and upload it to the central control host;

[0073] Step 3.2: The central control host uses image recognition technology to identify bird species, bird numbers, and activity trajectories. If any bird's activity trajectory gets too close to or even stops at a critical area of power equipment, the bird repellent operation is deemed a failure. The identified bird species, bird numbers, and activity trajectory information provide a reference for autonomous upgrades and replacements of the repellent strategy.

[0074] Through the secondary evaluation of bird repellent effect video based on image recognition technology, a second evaluation can be conducted based on the first evaluation of the device. The secondary evaluation can clearly and intuitively observe the movement trajectory of birds from approaching to leaving, and intuitively discover the hidden dangers caused by birds to power equipment during flight. The secondary evaluation makes the repellent effect evaluation more in-depth and accurate.

[0075] In the embodiment of the present invention, the specific steps of the autonomous upgrade process in step 4 include:

[0076] Step 4.1: The central control host collects long-term statistics on the primary evaluation results of the bird repellent effect of the main device processing module in step 2 and the secondary evaluation results of the bird repellent effect video of the central control host in step 3. The two evaluation results are combined to obtain a comprehensive bird repellent evaluation result for each bird repellent. If one of the two bird repellent evaluation results is judged as a failure, the repellent is judged as a failure; this result corresponds to the repellent strategy at that time.

[0077] Step 4.2: For the multiple sets of repelling strategies pre-stored in the main device processing module, the central control host calculates the repelling success rate of each repelling strategy over a period of time. If the bird repelling success rate corresponding to all the repelling strategies pre-stored in the main device processing module is less than a threshold, the central control host replaces each repelling strategy pre-stored in the main device processing module with the corresponding improved repelling strategy through the main device remote communication module to complete the autonomous upgrade; the improved repelling strategy is designed based on the bird species, bird population and activity trajectory information, and the improvements include: the light source intensity, light source flashing mode and frequency, and strong light start and stop conditions of the main device strong light repelling module and the sub-device strong light repelling module when working; the bird repelling sound set, sound decibel level, and sound start and stop conditions played by the main device sound repelling module and the sub-device sound repelling module when working; and the ultrasonic frequency and ultrasonic start and stop conditions emitted by the main device ultrasonic repelling module and the sub-device ultrasonic repelling module when working.

[0078] The main device processing module evaluates the repelling effect once and switches the repelling strategy within the main device to complete the small closed loop of dynamic update of the repelling strategy. The comprehensive repelling evaluation and the complete set of autonomous upgrades and replacements of the repelling strategy complete the large closed loop of dynamic update of the bird repelling strategy. The dynamically updated bird repelling strategy can effectively reduce the adaptability of birds and significantly improve the long-term success rate of bird repelling, effectively overcoming the mechanical rigidity of previous bird repelling devices.

[0079] In the embodiment of the present invention, the bird damage assessment process in step 5 specifically includes the following steps:

[0080] Step 5.1: The main device processing module periodically activates the main device video module to capture the target area and upload the captured images to the central control host;

[0081] Step 5.2: The central control host uses image recognition technology to identify bird nests in the target area. Based on the identification results and the bird activity trajectories obtained through image recognition technology, the host conducts bird damage analysis and classifies the bird damage level. If the damage is severe, human intervention is required. The bird damage level classification is shown in the table below:

[0082] grade Bird damage serious There is a bird's nest More serious No bird nests, birds staying generally There is bird activity, but no birds are staying. good No bird activity

[0083] In the embodiment of the present invention, the specific steps of regional linkage bird repelling in step 1.6 include:

[0084] Step 6.1: If the analysis result of a main device processing module shows that there is bird activity in the target area of the smart bird repellent system, the detection information will be uploaded to the central control host;

[0085] Step 6.2: The central control host searches for a smart bird repellent system within the vicinity of the smart bird repellent system that has detected the bird, and checks whether there is a smart bird repellent system whose distance to the smart bird repellent system is less than a threshold. If so, the central control host turns on the strong light bird repellent module in each device of the smart bird repellent system that meets the distance condition and points it towards the smart bird repellent system that has detected the bird, to perform regional collaborative bird repellent.

[0086] It should be understood that the above-mentioned embodiments are merely illustrative and non-restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present invention.
