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, device, and medium for a photovoltaic sound barrier. Background Art

[0002] Photovoltaic sound barriers have been widely used as facilities to alleviate urban traffic noise pollution. Combining photovoltaic cells with sound barriers can not only effectively reduce traffic noise but also convert solar energy into electrical energy for supply to other road facilities.

[0003] Currently, the form of photovoltaic sound barriers is mainly semi-closed. The upper part of the photovoltaic sound barrier is a photovoltaic module, and its photovoltaic module can rotate to track the azimuth angle of the sun to achieve maximum power generation. At the same time, considering the visual comfort requirements of drivers during vehicle driving, the middle part of the photovoltaic sound barrier is usually set as a transparent sound barrier to ensure the visual field requirements of drivers. 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 design of photovoltaic sound barriers, the following technical defects exist:

[0005] (1) Only photovoltaic modules are installed on the upper part of the photovoltaic sound barrier, and the area of the sound barrier is not fully utilized, resulting in a low photovoltaic installed capacity and insufficient power generation of the photovoltaic sound barrier.

[0006] (2) The existing photovoltaic sound barriers only rely on the sound insulation board and transparent sound barrier in the lower part to achieve the sound insulation function. The addition of photovoltaic modules has significantly reduced the area of the sound insulation function area, and the sound insulation effect is limited.

[0007] (3) The existing angle-adjustable photovoltaic sound barriers only consider the convenience of personnel cleaning and the improvement of 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, when the photovoltaic module is at a specific angle, the area of the sound insulation function area of the photovoltaic sound barrier is significantly reduced, thereby affecting the sound insulation and noise reduction effect.

[0008] 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 needs to be urgently solved by those skilled in the art. Summary of the Invention

[0009] In view of the above-mentioned disadvantages and deficiencies of the prior art, the present invention provides a dynamic control method, system, device, and medium for a photovoltaic sound barrier, which solves the technical problems of low intelligent control degree of existing photovoltaic sound barriers and poor synergistic effect between light energy utilization and sound insulation effect.

[0076] To better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

On the contrary, these embodiments are provided to enable a more clear and thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0077] Reference Figure 1 As shown, a dynamic control method for a photovoltaic sound barrier proposed in this embodiment includes:

[0078] S100. According to the obtained environmental information on the road, obtain the optimal coverage rate of the photovoltaic cells in the fixed semi-transparent photovoltaic sound barrier, so as to dynamically adjust the transparency of the fixed semi-transparent photovoltaic sound barrier based on the optimal coverage rate.

[0079] By the environmental information on the road, dynamically adjust the coverage area of the photovoltaic cells or the width of the photovoltaic cells in the fixed semi-transparent photovoltaic sound barrier, which can ensure the power generation of the fixed semi-transparent photovoltaic sound barrier while taking into account the sight requirements of the driver.

[0080] In this embodiment, before step S100, the following steps F100-F300 are further included:

[0081] F100. Under different brightness conditions, obtain the visual feedback information of users on the fixed semi-transparent photovoltaic sound barrier with different photovoltaic cell coverage rates.

[0082] For example, set the outdoor brightness to four levels, namely natural dark environment (brightness value lower than 10 lux), low brightness environment (brightness value between 10 lux and 100 lux), medium brightness environment (brightness value between 100 lux and 1000 lux), and high brightness environment (brightness value higher than 1000 lux), and then respectively count the visual feedback information of 100 users on different photovoltaic cell coverage rates at the same distance from the fixed semi-transparent photovoltaic sound barrier in the four brightness level environments. Among them, the visual feedback information has only two feedback options, namely good sight and poor sight.

[0083] F200. According to the visual feedback information, obtain the optimal values of the photovoltaic cell coverage rates in the fixed semi-transparent photovoltaic sound barrier under different brightness conditions.

[0084] F300 constrains the optimal value downward based on the obtained meteorological data to obtain the optimal value of the photovoltaic cell coverage rate in each brightness condition of the fixed semi-transparent photovoltaic sound barrier under different meteorological conditions.

[0085] For example, the meteorological conditions include heavy rain, rain, cloudy days, and sunny days. Under different weather conditions, different impacts will be exerted on the driver's line of sight (good line of sight on sunny days, poor line of sight on heavy rain, rain, and cloudy days). Especially in rainy and cloudy weather, the power generation power of the photovoltaic cells is almost 0. Therefore, in the same brightness environment, if it is rainy and cloudy weather, the photovoltaic cell coverage rate can be reduced, and even the photovoltaic cell coverage rate can be adjusted to 0.

[0089] S130. Select the optimal coverage rate from the coverage rate range according to the road brightness information to dynamically adjust the transparency of the fixed semi-transparent photovoltaic sound barrier based on the optimal coverage rate.

[0090] S200. Obtain the first tilt angle when the noise reduction effect of the rotary photovoltaic sound barrier is optimal and the second tilt angle when the power generation power of the rotary photovoltaic sound barrier is optimal according to the preset acoustic analysis model and photovoltaic power generation model.

[0091] In this embodiment, step S200 may include the following sub-steps S210 - S230:

[0097] S213. According to the conditional parameters, combined with the set sound source point and sound receiving point, an acoustic analysis model is constructed.

[0098] In a specific embodiment, according to Figure 3 the conditional parameter data included in the schematic diagram of the noise diffraction attenuation of the photovoltaic sound barrier shown, an acoustic analysis model is constructed, and then the acoustic analysis model is meshed to obtain the sound pressure level in the noise reduction area behind the photovoltaic sound barrier under the influence of the photovoltaic sound barrier, so as to obtain the noise reduction effect, and a database of the mapping relationship between the noise reduction effect and the tilt angle of the photovoltaic sound barrier is established. The tilt angles of the photovoltaic sound barrier include at least 15°, 30°, 45°, 60°, 75°, and 90°. Among them, the mathematical expression of the acoustic analysis model is:

[0099] (1)

[0100] In formula (1), is the noise reduction effect, dB is the measurement unit of the noise reduction effect: decibel, is the distance from the sound source point to the vertex (diffraction point) of the photovoltaic sound barrier, is the distance from the sound receiving point to the vertex 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 receiving point and the photovoltaic sound barrier, δ ( u ) is the transition function, is the distance from the sound source point to the sound receiving point.

[0101] S214. According to the historical working data of the photovoltaic sound barrier and the angle information of the photovoltaic sound barrier, combined with the obtained solar altitude angle, a photovoltaic power generation model is constructed.

[0102] In a specific embodiment, PVsyst software is used for simulation. The photovoltaic modules face due south and are installed at a fixed inclination angle. By changing the inclination angle of the photovoltaic modules, three sets of data of the total annual radiation amount are obtained, namely the conversion factor FT (the ratio of inclined-plane radiation to horizontal radiation), the loss ratio, and the total radiation amount on the daylighting surface. When both FT and the inclined-plane irradiation amount are maximum and the loss ratio is 0.0%, the corresponding inclination angle and azimuth angle of the photovoltaic modules reach the optimum. Then, batch simulations in different directions are carried out through PVsyst software, a photovoltaic power generation model of the photovoltaic panel at different inclination angles is established, and a database of the mapping relationship between the photovoltaic power generation power and the inclination angle of the photovoltaic sound barrier is established. The inclination angle of the photovoltaic sound barrier includes at least 15°, 30°, 45°, 60°, 75°, and 90°. Among them, the mathematical expression of the photovoltaic power generation model is:

[0107] S300. Establish a decision optimization model based on the weight distribution of the first inclination angle and the second inclination angle, and correct 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.

[0108] In this embodiment, step S300 may include the following sub-steps S310 - S330:

[0109] S310. Determine the weight coefficients of the first tilt angle and the second tilt angle according to the obtained working requirement information of the rotary photovoltaic sound barrier.

[0111] S330. Modify the weight coefficients in the initial decision optimization model according to the power generation amount of the fixed semi-transparent photovoltaic sound barrier to obtain the decision optimization model.

[0112] Further, step S330 may include the following steps S331 - S332:

[0113] S331. Obtain the power generation amount of the fixed semi-transparent photovoltaic sound barrier, and determine whether the power generation amount is less than the set threshold.

[0114] S332a. When the power generation amount is less than the set threshold, determine the initial decision optimization model as the decision optimization model.

[0116] In a specific embodiment, an initial decision optimization model (3) is established, where the normalized weight coefficients of the first tilt angle and the second tilt angle are both set to 0.5. When the power generation amount of the fixed semi-transparent photovoltaic sound barrier is not less than the set threshold at this time, and the power generation amount of the fixed semi-transparent photovoltaic sound barrier is 0.5 times the power generation amount at the optimal tilt angle of the rotary photovoltaic sound barrier, adjust the weight coefficient of the second tilt angle to 0.35 and adjust the weight coefficient of the second tilt angle to 0.65. Since the fixed semi-transparent photovoltaic sound barrier assists in power generation, increasing the total power generation amount, the power generation weight ratio of the rotary photovoltaic sound barrier can be appropriately reduced to increase the weight ratio of the noise reduction effect, so that the photovoltaic sound barrier can improve the noise reduction effect while ensuring a high power generation amount, thereby improving the synergistic effect of light energy utilization and sound insulation effect.

[0133] In summary, the present invention provides a dynamic control method, system, device, and medium for a photovoltaic sound barrier. First, based on the environmental information on the road, the optimal coverage rate of the 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. Second, since the tilt angle of the rotary photovoltaic sound barrier will change the multiple reflections of sound waves between the vehicle and the barrier, an acoustic analysis model is established in the present invention to obtain the mapping relationship between the tilt angle of the rotary photovoltaic sound barrier and the noise reduction effect. Third, since the tilt angle of the rotary photovoltaic sound barrier will change the maximum direct sunlight received by the photovoltaic panel, a photovoltaic power generation model is established in the present invention to obtain the mapping relationship between the tilt angle of the rotary photovoltaic sound barrier and the dynamic photovoltaic power generation power. Finally, based on the tilt angle of the rotary photovoltaic sound barrier, the noise reduction effect and photovoltaic power generation power that the photovoltaic sound barrier can achieve are calculated. Then, a decision optimization model for controlling the angle of the rotary photovoltaic sound barrier is established, and the two optimization objectives of the best noise reduction effect and the highest power generation power are normalized and transformed into a single-objective optimization problem. Then, based on this decision optimization model, the rotary photovoltaic sound barrier is optimized under real-time environmental conditions (real-time road area noise, meteorological parameters, and the power generation of the fixed semi-transparent photovoltaic sound barrier) until the objective function reaches the maximum value, that is, the optimal tilt angle of the rotary photovoltaic sound barrier is obtained, achieving a double improvement in noise reduction effect and power generation efficiency.
