Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power facility safety and ecological protection, and particularly relates to an intelligent anti-bird collision warning method and system and a medium. BACKGROUND

[0002] With the continuous advancement of power grid construction in plateau regions, power transmission lines have become important infrastructure in the region. However, the unique geographical and ecological environment of the plateau region also poses a serious challenge to the safe and stable operation of power transmission lines and the protection of the ecological environment. Among them, the collision problem between power transmission lines, especially the ground wires (or lightning arresters) erected above them with small diameters, and the flight activities of large rare birds has become an urgent technical problem to be solved.

[0003] In the open plateau region, the flight height of large birds (such as black-necked cranes, golden eagles, etc.) overlaps with the height of power transmission lines, especially the ground wires. These ground wires have relatively thin diameters, and in a specific visual environment, the contrast between their own color and the sky background is extremely low, making it difficult for birds in flight to identify them in time. Specifically, during the dawn and dusk periods, the light is insufficient, the backlight flight leads to visual glare, or encounters rain, snow, fog, haze and other adverse weather, the sky background is complex, the visibility is reduced, and the visual salience of the wires is further reduced. Large birds flying at high speed are extremely prone to collisions when they face such visually invisible wires, resulting in bird casualties (especially endangered species), wire damage and even power grid failure, posing a serious threat to ecological protection and power grid safety.

[0004] To alleviate this problem, the most common measure in the industry is to install reflective warning balls at intervals on the power transmission wires. This technical solution mainly relies on the reflective material on the surface of the ball to enhance its visibility in the bird's field of vision by reflecting sunlight. However, this traditional solution has inherent and difficult-to-overcome technical defects, making it impossible to achieve effective warning in all-weather and all-time periods:

[0005] Passively dependent on external light sources, effective warning period is limited: the reflective warning ball itself does not emit light, and its warning effect completely depends on the environmental light conditions. In the dawn and dusk, night and other periods of weak environmental light, and in the backlight state (the bird flies facing the light source, and the warning ball is backlit), the ball is almost unable to reflect light of sufficient intensity, and the warning effect is greatly reduced or even completely ineffective.

[0006] Performance deteriorates sharply in bad weather: In rain, snow, fog, dust and other bad weather conditions, not only is the ambient light level low, but the suspended particles or water droplets in the air will also cause serious scattering and attenuation effects on the light. This results in a significant weakening of the reflected light during transmission, even if there is ambient light, making the visible distance and eye-catching degree of the warning ball significantly reduced, and unable to provide reliable protection in bad flying conditions when birds need warning the most.

[0007] Limited viewing angle and susceptible to pollution: The reflected light of the reflective material has a specific directionality, and only works best within a certain angle range, and cannot achieve omnidirectional warning. In addition, in the field environment, the surface of the ball is easy to accumulate dust, adhere to ice and snow or bird droppings, which seriously pollutes the reflective coating, making its reflectivity permanently or periodically decreased, with high maintenance cost and difficult to sustain the effect.

[0008] Therefore, the existing reflective warning ball, due to its passive reflection working principle, is subject to the changeable environmental conditions, has obvious functional empty window period, and cannot provide continuous, stable and effective visual warning signal for flying birds in key moments of insufficient light or bad weather, thus it is difficult to fundamentally solve the bird collision problem of power transmission lines in plateau areas.

[0009] In summary, there is an urgent need in the art for a new warning device or method that can overcome the above technical limitations, actively adapt to complex environmental changes, and achieve all-weather and high-reliability visual warning to effectively reduce the risk of bird collision. SUMMARY

[0010] To solve the problem that the conductor of the power transmission line in the plateau area is difficult to be recognized by the flying birds in the morning and evening, under the background of backlight or bad weather, leading to collision accidents, and the inherent technical defects of the reflective warning ball as the existing main measure lead to the problem that all-weather effective warning cannot be achieved; the purpose of the present application is to provide a power system harmonic detection method, system and medium, which improves the mature structure and installation method of the traditional reflective warning ball, intelligently upgrades the existing technology based on the strategy direction of active visual enhancement and guidance; by integrating the perception and lighting system, and based on bird visual ecology, while retaining the advantages of passive reflection mode, the ability to emit bird sensitive spectrum (such as ultraviolet light) and random switching of multiple preset flashing modes is added, forming an all-weather, adaptive and high-efficiency intelligent anti-bird collision solution, which upgrades the warning device from passive reflection to active perception and lighting, significantly improves the recognizability of the conductor, and guides the birds to avoid safely.

[0011] The above technical purpose of the present application is realized by the following technical scheme:

[0012] The present application provides an intelligent anti-bird collision warning method, which comprises:

[0013] Periodically collect ambient light intensity data in the target power transmission line area;

[0014] A preset light intensity threshold is used to determine whether the ambient light intensity is lower than the light intensity threshold.

[0015] If the ambient light intensity is lower than the light intensity threshold, a warning light signal will be emitted in the first mode; the first mode is an active light emission mode.

[0016] If the ambient light intensity is not lower than the light intensity threshold, a warning light signal will be emitted in the second mode; the second mode is a passive reflective mode.

[0017] A further optimization is that the warning light signal emitted by the first mode is a light signal that randomly switches between multiple preset flashing modes.

[0018] A further optimization is that the warning light signal emitted by the first mode is a bird-sensitive spectral light source signal.

[0019] A further optimization is that the bird-sensitive spectral light source includes ultraviolet LEDs or specific blue LEDs.

[0020] The further optimized solution is to use the second mode as the default setting for issuing warning light signals, use ambient light intensity below the light intensity threshold as the triggering mechanism for the first mode, and use ambient light intensity above or equal to the light intensity threshold as the deactivation mechanism for the first mode.

[0021] A further optimized solution is that the warning light signal emitted in the second mode is a reflected natural light signal.

[0022] This solution also provides an intelligent bird strike warning system to implement the aforementioned intelligent bird strike warning method; the system includes:

[0023] The acquisition module is used to periodically collect the ambient light intensity of the target area;

[0024] The judgment module is used to preset the light intensity threshold and determine whether the ambient light intensity is lower than the light intensity threshold;

[0025] The driving module is used to emit a warning light signal in a first mode when the ambient light intensity is lower than the light intensity threshold; the first mode is an active light emission mode; and to emit a warning light signal in a second mode when the ambient light intensity is not lower than the light intensity threshold; the second mode is a passive reflective mode.

[0026] A further optimized solution is that the system is integrated into a bird strike warning ball, which includes an upper hemisphere and a lower hemisphere;

[0027] The lower hemisphere is a light-transmitting shell, which integrates a light-emitting module, a judgment module, and a driving module; the light-emitting module is used to emit a bird-sensitive spectrum light source signal as a warning light signal.

[0028] The upper hemisphere is a reflective shell used to reflect natural light signals as warning light signals.

[0029] The further optimized solution also includes a main power supply module and an auxiliary power supply module;

[0030] The main power supply module utilizes the alternating magnetic field of the target transmission line area to induce power through the magnetic core and coil, providing main power to the system.

[0031] The auxiliary power supply module is a flexible solar film that is attached to the surface of the bird strike warning ball to convert solar energy into electrical energy to provide auxiliary power to the system.

[0032] This solution also provides a computer-readable medium having a computer program stored thereon, which, when executed by a processor, can implement an intelligent bird-collision warning method as described above.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. This solution provides an intelligent bird collision warning method, system, and medium. It improves upon the mature structure and installation method of traditional reflective warning balls, and upgrades existing technologies intelligently based on the strategy of active visual enhancement and guidance. By integrating sensing and luminescence systems, and based on bird visual ecology, it retains the advantages of passive reflective mode while adding the ability to emit bird-sensitive spectra (such as ultraviolet light) and dynamically flash multiple preset flashing modes, forming an all-weather, adaptive, and high-efficiency intelligent bird collision prevention solution. This upgrades the warning device from passive reflection to active sensing and luminescence, fundamentally improving the visibility of the wires and guiding birds to safely avoid collisions.

[0035] 2. This solution provides an intelligent bird collision warning method, system, and medium. Through intelligent coordination, it inherits and enhances the excellent performance of traditional reflective balls during the day, and activates active light emission when there is insufficient light, effectively compensating for the blind spots of traditional solutions in low-light environments. In the active light emission mode (first mode), it adopts a random switching flashing strategy of multiple preset flashing modes to prevent birds from becoming accustomed to it, and a warning strategy of co-emitting ultraviolet light and specific blue light to maximize birds' visual perception.

[0036] 3. This solution provides an intelligent bird strike warning method, system and medium. The miniaturized hybrid energy system ensures energy self-sufficiency, and the active light-emitting module is built into the spherical shell, so its performance is not affected by external pollution.

[0037] To more clearly illustrate the technical solutions of the exemplary embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below. It should be understood that the following drawings only show some embodiments of the present invention and should not be considered as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort. In the drawings:

[0038] Figure 1 A schematic diagram of the intelligent bird strike warning method;

[0039] Figure 2 This is a schematic diagram of an intelligent bird strike warning system.

[0040] Figure 3 This is a schematic diagram illustrating the principle of intelligent bird strike prevention warning. Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0042] In high-altitude areas, power transmission line conductors are difficult for birds to spot in time during dawn and dusk, against the light, or in inclement weather, leading to collisions. Reflective warning balls, as the primary existing measure, have inherent technical limitations that prevent them from providing effective all-weather warnings. Therefore, this solution provides the following embodiments to address the aforementioned technical problems:

[0043] Example 1

[0044] This embodiment provides an intelligent bird strike warning method, such as Figure 1 As shown, the method includes:

[0045] Step 1: Periodically collect ambient light intensity data in the target power transmission line area;

[0046] Step 2: Preset a light intensity threshold and determine whether the ambient light intensity is lower than the light intensity threshold;

[0047] Step 3: If the ambient light intensity is lower than the light intensity threshold, a warning light signal is emitted in the first mode; the first mode is the active light emission mode.

[0048] If the ambient light intensity is not lower than the light intensity threshold, a warning light signal will be emitted in the second mode; the second mode is a passive reflective mode.

[0049] The warning light signal emitted by the first mode is a light signal that randomly switches between multiple preset flashing modes.

[0050] The warning light signal emitted by the first mode is a light source signal that is sensitive to the spectrum of birds.

[0051] The bird-sensitive spectral light source includes ultraviolet LEDs or specific blue LEDs. Unlike humans' trichromatic vision, birds possess a tetrachromatic visual system that includes ultraviolet (UV-A) perception. Their retinas have cone cells that are highly sensitive to ultraviolet light (peak wavelength approximately ~360 nm) and short-wavelength blue light (peak wavelength approximately ~450 nm). Therefore, this scheme uses ultraviolet LEDs emitting wavelengths in the range of 315-400 nm and specific blue light in the range of 440-460 nm to most effectively stimulate the bird's visual system, enabling it to perceive complex backgrounds and low light conditions.

[0052] This spectral optimization based on receptor biology enables rapid identification of warning targets under specific lighting conditions, thereby achieving efficient early warning.

[0053] This strategy offers a fundamental improvement in effectiveness compared to traditional warning colors (red) chosen based on human visual experience.

[0054] In this embodiment, under the active light emission mode (first mode), a dynamic flashing strategy that randomly switches between multiple preset flashing modes is adopted to prevent birds from becoming accustomed to it, and a warning strategy that uses ultraviolet light and specific blue light to emit light in synergy to maximize birds’ visual perception is adopted.

[0055] The second mode is set as the default setting for issuing warning light signals. The first mode is triggered when the ambient light intensity is lower than the light intensity threshold, and the first mode is turned off when the ambient light intensity is higher than or equal to the light intensity threshold.

[0056] The warning light signal emitted in the second mode is a reflected natural light signal.

[0057] This method can be used not only for warning balls, but also for other areas that require all-weather warning, such as high-speed railway overhead contact lines, wind turbine blades, airport navigation obstacles, and any linear or point-like facilities that need to prevent bird collisions.

[0058] Example 2

[0059] This embodiment provides an intelligent bird strike warning system, such as Figure 2 As shown, a smart bird collision warning method for implementing Embodiment 1 is described; the system includes:

[0060] The acquisition module is used to periodically collect the ambient light intensity of the target area;

[0061] The judgment module is used to preset the light intensity threshold and determine whether the ambient light intensity is lower than the light intensity threshold;

[0062] The driving module is used to emit a warning light signal in a first mode when the ambient light intensity is lower than the light intensity threshold; the first mode is an active light emission mode; and to emit a warning light signal in a second mode when the ambient light intensity is not lower than the light intensity threshold; the second mode is a passive reflective mode.

[0063] The system is integrated into a bird strike warning ball, which includes an upper hemisphere and a lower hemisphere;

[0064] The lower hemisphere is a light-transmitting shell, which integrates a light-emitting module, a judgment module, and a driving module; the light-emitting module is used to emit a bird-sensitive spectrum light source signal as a warning light signal.

[0065] The upper hemisphere is a reflective shell used to reflect natural light signals as warning light signals.

[0066] The intelligent bird strike warning system also includes a main power supply module and an auxiliary power supply module;

[0067] The main power supply module utilizes the alternating magnetic field of the target transmission line area to induce power through the magnetic core and coil, providing main power to the system.

[0068] The auxiliary power supply module is a flexible solar film that is attached to the surface of the bird strike warning ball to convert solar energy into electrical energy to provide auxiliary power to the system.

[0069] like Figure 3 As shown, the intelligent bird collision warning system initializes upon power-up and enters a low-power standby mode. The acquisition module (ambient light sensor) periodically collects ambient light intensity data to determine whether the light intensity is below a preset threshold (this threshold corresponds to the light level at dawn / dusk or in inclement weather). If the light intensity is not below the preset threshold, the intelligent bird collision warning system remains in passive reflective mode (second mode), meaning the LED lights in the light-emitting module are turned off, consistent with the operation of traditional warning balls, relying on the upper hemisphere reflective film to complete the warning function. If the light intensity is below the threshold, the intelligent bird collision warning system intelligently switches to active light-emitting mode (first mode). The MCU, according to its built-in strategy, drives the ultraviolet LEDs, specific blue LEDs, and other bird-sensitive spectrum light sources in the light module to execute multiple preset flashing modes and randomly switch between them to compensate for the shortcomings of traditional methods.

[0070] Example 3

[0071] This embodiment provides a computer-readable medium storing a computer program thereon. The computer program, when executed by a processor, can implement an intelligent bird-collision warning method as described in Embodiment 1; specifically, it performs the following steps:

[0072] Step 1: Periodically collect ambient light intensity data in the target power transmission line area;

[0073] Step 2: Preset a light intensity threshold and determine whether the ambient light intensity is lower than the light intensity threshold;

[0074] Step 3: If the ambient light intensity is lower than the light intensity threshold, a warning light signal is emitted in the first mode; the first mode is an active light emission mode. If the ambient light intensity is not lower than the light intensity threshold, a warning light signal is emitted in the second mode; the second mode is a passive reflective mode.

[0075] Example 4

[0076] This embodiment provides a specific application of an intelligent bird collision warning method, specifically for the protection of rare birds (such as the black-necked crane).

[0077] The deployment scenario is: plateau wetlands, 110kV transmission lines, and a fixed flight corridor that black-necked cranes use for their morning and evening journeys.

[0078] Install a smart warning ball every 30 meters along the ground line;

[0079] In active mode, the MCU controls 3 UV-A LEDs and 2 high-brightness blue LEDs (wavelength 450nm) to work in a non-periodic cycle of "fast flash for 2 seconds - pause for 1 second - slow flash for 1 second";

[0080] The miniature CT ensures stable output when the line current is greater than 10A; the flexible solar film provides no less than 50mW of supplementary power under standard illumination; and the energy storage uses a 3.7V, 500mAh low-temperature button lithium battery.

[0081] The preset light intensity threshold is 100 Lux (typical dusk value).

[0082] Work process:

[0083] At sunset, if the ambient light intensity is detected to be below 100 Lux, the system automatically switches from mode two to mode one.

[0084] The lower half of the sphere emits dynamically changing UV blue light, which can drive black-necked cranes to sense the flashing array of lights hundreds of meters away and adjust their flight altitude in advance to pass safely. Throughout the night, it is powered by both inductive power and batteries. After sunrise, when the ambient light intensity is detected to be higher than 100 Lux, the system automatically switches from the first mode to the second mode, and at the same time, the solar thin film begins to replenish the battery with energy.

[0085] The intelligent bird collision warning method provided in this embodiment improves upon the mature structure and installation method of traditional reflective warning balls. It upgrades existing technologies with intelligence based on the strategy of active visual enhancement and guidance. By integrating sensing and luminescence systems and based on bird visual ecology, it retains the advantages of passive reflective mode while adding the ability to emit bird-sensitive spectra (such as ultraviolet light) and dynamically flash multiple preset flashing modes. This forms an all-weather, adaptive, and high-efficiency intelligent bird collision prevention solution, upgrading the warning device from passive reflection to active sensing and luminescence, fundamentally improving the visibility of the wires and guiding birds to safely avoid collisions.

[0086] The intelligent bird collision warning method provided in this embodiment inherits and enhances the excellent performance of traditional reflective balls during the day through intelligent coordination, and activates active light emission when there is insufficient light, completely eliminating the blind spot of protection; in the active light emission mode (first mode), a dynamic flashing strategy of randomly switching multiple preset flashing modes is adopted to prevent birds from getting used to it, and a warning strategy of co-emitting ultraviolet light and specific blue light is adopted to maximize the visual perception of birds.

[0087] The intelligent bird strike warning method provided in this embodiment features a miniaturized hybrid energy system that ensures energy self-sufficiency, and the active light-emitting module is built into the spherical shell, so its performance is not affected by external pollution.
