Description

Technical Field

[0001] The present invention relates to the technical field of road sound barriers, and in particular to a dynamic control method, system, equipment and medium of a photovoltaic sound barrier. Background Art

[0002] Photovoltaic sound barriers have been widely used in facilities to alleviate urban traffic noise pollution. Combining photovoltaic cells with sound barriers not only effectively reduces traffic noise, but also converts solar energy into electrical energy to supply other road facilities.

[0003] At present, the photovoltaic sound barrier is mainly in the form of semi-enclosed type. The upper part of the photovoltaic sound barrier is a photovoltaic module, which can track the azimuth of the sun by rotating to achieve maximum power generation. At the same time, considering the visual comfort needs of the driver during the driving process, the middle part of the photovoltaic sound barrier is usually set as a transparent sound barrier to ensure the driver's field of vision. Finally, the lower part of the photovoltaic sound barrier is set as an opaque sound insulation board to ensure the maximum sound insulation effect.

[0004] However, based on the existing photovoltaic sound barrier design, there are the following technical defects: (1) Photovoltaic modules are only installed on the upper part of the photovoltaic sound barrier, which fails to fully utilize the area of ​​the sound barrier. The photovoltaic installed capacity is relatively low, resulting in insufficient power generation of the photovoltaic sound barrier.

[0005] (2) The existing photovoltaic sound barrier only relies on the sound insulation board and transparent sound barrier at the bottom to achieve the sound insulation function. The addition of photovoltaic modules greatly reduces the area of ​​the sound insulation function area, limiting the sound insulation effect.

[0006] (3) The existing angle-adjustable photovoltaic sound barriers are only designed to facilitate cleaning and improve photovoltaic power generation efficiency, without considering the sound insulation effect of this part. Since the angle adjustment of the upper part of the photovoltaic sound barrier also affects its sound insulation effect, the sound insulation function area of ​​the photovoltaic sound barrier is greatly reduced at a specific angle of the photovoltaic module, thereby affecting the sound insulation and noise reduction effect.

[0007] Therefore, effectively realizing the coordinated control of sound, light and electricity of photovoltaic sound barriers on both sides of the road is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] refer to Figure 1 As shown, the present embodiment proposes a method for dynamic control of a photovoltaic sound barrier, which includes: S100. Obtain the optimal coverage rate of photovoltaic cells in the fixed semi-transparent photovoltaic sound barrier according to the acquired environmental information on the road, so as to dynamically adjust the transparency of the fixed semi-transparent photovoltaic sound barrier based on the optimal coverage rate.

[0031] Through environmental information on the road, the coverage area or width of the photovoltaic cells in the fixed semi-transparent photovoltaic sound barrier is dynamically adjusted, which ensures the power generation of the fixed semi-transparent photovoltaic sound barrier while taking into account the driver's vision requirements.

[0032] In this embodiment, before step S100, the following steps F100-F300 are also included: F100. Obtain users’ visual feedback information on fixed semi-transparent photovoltaic sound barriers with different photovoltaic cell coverage under different brightness conditions.

[0033] For example, the outdoor brightness is set to four levels, namely natural dark environment (brightness value lower than 10 lux), low brightness environment (brightness value between 10lux and 100 lux), medium brightness environment (brightness value between 100lux-1000lux) and high brightness environment (brightness value higher than 1000lux). Then, the visual feedback information of 100 users at different photovoltaic cell coverage rates at the same distance from the fixed translucent photovoltaic sound barrier in the four brightness level environments is counted. Among them, the visual feedback information has only two feedback options, namely good line of sight and poor line of sight.

[0034] F200. Based on visual feedback information, the optimal value of photovoltaic cell coverage in the fixed semi-transparent photovoltaic sound barrier under different brightness conditions is obtained.

[0035] F300. Based on the acquired meteorological data, the optimal value is constrained downward to obtain the optimal value of the photovoltaic cell coverage rate in the fixed semi-transparent photovoltaic sound barrier under various brightness conditions under different meteorological conditions.

[0036] For example, meteorological conditions include heavy rain, rain, cloudy days and sunny days. Different weather conditions will have different effects on the driver's vision (good vision on sunny days, poor vision in heavy rain, rain and cloudy days). Especially in rainy weather, the power generation power of photovoltaic cells is almost 0. Therefore, in the same brightness environment, if it is in rainy weather, the coverage rate of photovoltaic cells can be reduced, and can even be adjusted to 0.

[0037] In this embodiment, step S100 may include the following sub-steps S110-S130: S110: Obtain environmental information on the road including road brightness information and real-time weather information.

[0038] S120. Determine the coverage range of photovoltaic cells in the fixed semi-transparent photovoltaic sound barrier under the meteorological conditions based on the real-time meteorological information.

[0039] S130. According to the road brightness information, select the optimal coverage from the coverage range to dynamically adjust the transparency of the fixed semi-transparent photovoltaic sound barrier based on the optimal coverage.

[0040] S200. Based on the preset acoustic analysis model and photovoltaic power generation model, obtain the first tilt angle when the noise reduction effect of the rotating photovoltaic sound barrier is optimal and the second tilt angle when the photovoltaic power generation power of the rotating photovoltaic sound barrier is optimal.

[0041] In this embodiment, step S200 may include the following sub-steps S210-S230: S210. Construct an acoustic analysis model and a photovoltaic power generation model based on the acquired structural information and historical working data of the photovoltaic sound barrier.

[0043] S212. Perform geometric modeling on the photovoltaic sound barrier according to its structural information to obtain conditional parameters of the photovoltaic sound barrier, where the conditional parameters include height information, width information, thickness information, and angle information.

[0044] In a specific embodiment, a finite element calculation method is used to directly establish the sound barrier structure form in the geometry modeling module (Geometry) of Virtual.Lab (virtual laboratory), including the height information, width information, thickness information, angle information, material information, etc. of the photovoltaic sound barrier.

[0045] S213. Construct an acoustic analysis model based on the conditional parameters and the set sound source points and sound receiving points.

[0046] In a specific embodiment, according to Figure 3 The conditional parameter data contained in the photovoltaic sound barrier noise diffraction attenuation schematic diagram is used to construct an acoustic analysis model, and then the acoustic analysis model is meshed to obtain the sound pressure level of the noise reduction area behind the photovoltaic sound barrier under the influence of the photovoltaic sound barrier to obtain the noise reduction effect, and a database of the mapping relationship between the noise reduction effect and the photovoltaic sound barrier inclination angle is established. The photovoltaic sound barrier inclination angle includes at least 15°, 30°, 45°, 60°, 75°, and 90°. Among them, the mathematical expression of the acoustic analysis model is: (1) In formula (1), For noise reduction effect, dB The unit of measurement for noise reduction effect: decibel, is the distance from the sound source to the apex (diffraction point) of the photovoltaic sound barrier, is the distance from the sound collection point to the top of the photovoltaic sound barrier, θ S is the angle between the sound propagation path from the sound source point to the diffraction point and the photovoltaic sound barrier, θ R is the angle between the sound propagation path from the diffraction point to the sound collection point and the photovoltaic sound barrier, δ ( u ) is the transition function, is the distance from the sound source to the sound receiving point.

[0047] S214. Construct a photovoltaic power generation model based on the historical working data of the photovoltaic sound barrier and the angle information of the photovoltaic sound barrier in combination with the acquired solar high angle.

[0048] In a specific embodiment, PVsyst software is used for simulation. The photovoltaic module faces due south and is installed at a fixed inclination angle. By changing the installation inclination angle of the photovoltaic module, three sets of data on the total annual radiation are obtained, namely, the conversion coefficient FT (the ratio of inclined radiation to horizontal radiation), the loss ratio, and the total radiation of the lighting surface. When the FT and the inclined surface irradiation are both maximum and the loss ratio is 0.0%, the inclination angle and azimuth angle corresponding to the photovoltaic module reach the optimal value. Then, batch simulations in different directions are performed using PVsyst software to establish a photovoltaic power generation model for photovoltaic panels at different inclination angles, and a database of the mapping relationship between photovoltaic power generation power and the inclination angle of photovoltaic sound barriers is established. The inclination angles of photovoltaic sound barriers include at least 15°, 30°, 45°, 60°, 75°, and 90°. Among them, the mathematical expression of the photovoltaic power generation model is: (2) In formula (2), P g is the photovoltaic power generation power, P ref is the rated power generation, f pv is the degradation factor, H ref is the standard solar radiation, is the solar radiation correction factor, H β is the horizontal direct solar radiation on the inclined surface, is the open circuit voltage coefficient, T c ( t )for t The actual ambient temperature at the moment, T c,refRepresents the ambient temperature under which the rated power generation is tested.

[0050] S230. Analyze the mapping relationship between the tilt angle of the rotating photovoltaic sound barrier and the photovoltaic power generation power through a photovoltaic power generation model to obtain a second tilt angle when the photovoltaic power generation power of the rotating photovoltaic sound barrier is optimal.

[0051] S300. Establish a decision optimization model based on the weight distribution of the first inclination angle and the second inclination angle, and modify the weight coefficient in the decision optimization model based on the optimal coverage rate of the photovoltaic cells in the fixed semi-transparent photovoltaic sound barrier.

[0052] In this embodiment, step S300 may include the following sub-steps S310-S330: S310. Determine the weight coefficients of the first tilt angle and the second tilt angle based on the obtained working requirement information of the rotating photovoltaic sound barrier.

[0053] S320: Taking the first tilt angle and the second tilt angle as optimization targets and combining the weight coefficients of the first tilt angle and the second tilt angle, an initial decision optimization model is established.

[0054] S330. According to the photovoltaic power generation of the fixed semi-transparent photovoltaic sound barrier, the weight coefficient in the initial decision optimization model is modified to obtain a decision optimization model.

[0055] Further, step S330 may include the following steps S331-S332: S331. Obtain the photovoltaic power generation of the fixed semi-transparent photovoltaic sound barrier, and determine whether the photovoltaic power generation is less than a set threshold.

[0056] S332a. When the photovoltaic power generation is less than the set threshold, the initial decision optimization model is determined to be the decision optimization model.

[0057] S332b. When the photovoltaic power generation is not less than the set threshold, the weight coefficient of the first tilt angle in the initial decision optimization model is adjusted upward and the weight coefficient of the second tilt angle in the initial decision optimization model is adjusted downward according to the photovoltaic power generation to obtain a decision optimization model.

[0058] In a specific embodiment, an initial decision optimization model (3) is established, wherein the weight coefficients of the first tilt angle and the second tilt angle are both normalized to 0.5. When the photovoltaic power generation of the fixed semi-transparent photovoltaic sound barrier is not less than the set threshold, and the photovoltaic power generation of the fixed semi-transparent photovoltaic sound barrier is 0.5 times the power generation of the rotating photovoltaic sound barrier at the optimal tilt angle, the weight coefficient of the second tilt angle is adjusted to 0.35 and the weight coefficient of the second tilt angle is adjusted to 0.65. Since the fixed semi-transparent photovoltaic sound barrier assists photovoltaic power generation, the total amount of photovoltaic power generation is increased, and the weight ratio of the rotating photovoltaic sound barrier power generation can be appropriately lowered to increase the weight ratio of the noise reduction effect, so that the photovoltaic sound barrier can improve the noise reduction effect while ensuring high photovoltaic power generation, thereby improving the synergistic effect of light energy utilization and sound insulation effect.

[0070] Specifically, in the dynamic control process of the photovoltaic sound barrier, the precise control of the transparency of the fixed semi-transparent photovoltaic sound barrier and the precise control of the tilt angle of the rotating photovoltaic sound barrier are crucial. The computer-readable medium stores executable instructions for implementing the dynamic control method of the photovoltaic sound barrier. When these instructions are executed by the processor, it can ensure that the precise control of the transparency of the fixed semi-transparent photovoltaic sound barrier and the precise control of the tilt angle of the rotating photovoltaic sound barrier can be completed, which improves the accuracy of the dynamic control of the photovoltaic sound barrier.

First, according to the environmental information on the road, the optimal coverage rate of photovoltaic cells in the fixed semi-transparent photovoltaic sound barrier is obtained to dynamically control the transparency of the fixed semi-transparent photovoltaic sound barrier. Secondly, since the inclination angle of the rotating photovoltaic sound barrier will change the multiple reflections of sound waves between the vehicle and the barrier, the present invention establishes an acoustic analysis model to obtain the mapping relationship between the inclination angle of the rotating photovoltaic sound barrier and the noise reduction effect. Thirdly, since the inclination angle of the rotating photovoltaic sound barrier will change the maximum direct sunlight that the photovoltaic panel can receive, the present invention establishes a photovoltaic power generation model to obtain the mapping relationship between the inclination angle of the rotating photovoltaic sound barrier and the dynamic photovoltaic power generation power. Finally, based on the inclination angle of the rotating photovoltaic sound barrier, the noise reduction effect and photovoltaic power generation that the photovoltaic sound barrier can achieve are calculated. Then, a decision optimization model for the angle control of the rotating photovoltaic sound barrier is established. The two optimization objectives of optimal noise reduction effect and highest power generation are normalized and converted into a single-objective optimization problem. Then, based on the decision optimization model, the rotating photovoltaic sound barrier is optimized under real-time environmental conditions (real-time road noise, meteorological parameters, and power generation of fixed translucent photovoltaic sound barriers) until the objective function reaches its maximum value, that is, the optimal inclination angle of the rotating photovoltaic sound barrier is obtained, thereby achieving a dual improvement in noise reduction effect and power generation efficiency.
