All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Example 1
Fig. 1 shows an intelligent street lamp control method based on an edge computing gateway, which comprises the following steps:
step S1: collecting solar panel light transmittance information, calculating solar panel light transmittance according to the solar panel light transmittance information, and calculating comprehensive light transmittance through analyzing deviation conditions that the solar panel light transmittance is smaller than a light transmittance threshold value.
Step S2: collecting solar energy conversion efficiency information, calculating photoelectric conversion efficiency, calculating a photoelectric conversion efficiency average value according to the photoelectric conversion efficiency, and calculating a photoelectric conversion efficiency stable change coefficient according to the photoelectric conversion efficiency.

In step S1, light transmittance information of the solar panel is collected, where the light transmittance of the solar panel refers to the ability of solar light to pass through the solar panel, i.e. how much proportion of the light can pass through the solar panel without being absorbed or reflected after entering the solar panel; the light transmittance of the solar panel is very important to the effect of the solar panel on the absorption of solar energy, and when the solar light irradiates the surface of the solar panel, a part of light is absorbed by the solar panel and converted into electric energy; another part of the light is reflected or refracted and cannot be utilized by the solar panel. The high light transmittance means that more light can pass through the solar panel to be absorbed, thereby improving the photoelectric conversion efficiency of the solar panel; the low light transmittance can reduce the solar energy utilization efficiency of the solar panel and reduce the output of electric energy.
Factors that affect the light transmittance of a solar panel include, but are not limited to:
and (3) material degradation: the materials used for the solar panel can be degraded with the passage of time, so that the change of optical performance is caused, and the light transmittance is influenced; surface contamination: contaminants on the surface of the solar panel, such as dust, grease, leaves and the like, can reduce the light transmission capacity and influence the light transmittance; surface damage: damage such as scratches, cracks or abrasion on the surface of the solar panel can lead to light reflection and scattering, reduce light transmission capacity and influence light transmittance; dust accumulation: in the long-term use process, certain dust can be accumulated on the solar panel, and the light transmission efficiency is affected.
The light transmittance information of the solar panel is reflected through comprehensive light transmittance, and the acquisition logic of the comprehensive light transmittance is as follows:
setting a solar energy acquisition interval, uniformly setting a plurality of light transmittance monitoring points in the solar energy acquisition interval, wherein the light transmittance monitoring points correspond to the light transmittance of the solar panel, and calculating the light transmittance of the solar panel corresponding to each light transmittance monitoring point, wherein the expression is as follows:； wherein ,/>The transmittance, the transmitted light intensity and the incident light intensity of the solar panel are respectively.
The higher light transmittance of the solar panel means that more solar rays can penetrate the solar panel to be absorbed, thereby improving the photoelectric conversion efficiency of the solar panel; conversely, a lower transmittance of the solar panel means that less solar rays penetrate the solar panel to be absorbed, and the lower the photoelectric conversion efficiency of the solar panel.
The transmitted light intensity refers to the intensity of light passing through the solar panel; the incident light intensity refers to the intensity of light striking the surface of the solar panel.
And setting a light transmittance threshold, wherein when the light transmittance of the solar panel is smaller than the light transmittance threshold, the light transmittance of the solar panel is lower, and the adverse effect on the photoelectric conversion efficiency of the solar panel is larger.
The method comprises the steps of obtaining the quantity of solar panel light transmittance, corresponding to the light transmittance monitoring points, in a solar energy obtaining interval, smaller than a light transmittance threshold, numbering the solar panel light transmittance, corresponding to the light transmittance monitoring points, in the solar energy obtaining interval, and reflecting the light transmittance in the solar energy obtaining interval more accurately by analyzing the deviation condition that the light transmittance of the solar panel is smaller than the light transmittance threshold.
The comprehensive light transmittance is calculated, and the expression is as follows:； wherein ,respectively the comprehensive light transmittance and the number of +.>Solar panel light transmittance and light transmittance threshold,in order to obtain the quantity of solar panel light transmittance that the solar panel light transmittance corresponding to the light transmittance monitoring point is smaller than the light transmittance threshold value in the interval of solar energy +.>For the number of solar panel light transmittance, which is smaller than the light transmittance threshold value, corresponding to the light transmittance monitoring point in the solar energy acquisition interval, +.>，/>Is a positive integer greater than 1. The larger the comprehensive light transmittance is, the larger the deviation between the light transmittance of the solar panel and the light transmittance threshold value is, and the larger the adverse effect on the photoelectric conversion efficiency of the solar panel is.
The solar energy acquisition interval is a time period for the solar intelligent street lamp to absorb solar energy and convert the solar energy into electric energy in daytime, and the specific setting is set by a person skilled in the art according to the actual situation of the area and other actual situations, for example, the setting can be set to 05:00-18:00, which are not described in detail herein.
The light transmittance monitoring point is a time point for monitoring the light transmittance of the solar panel in the solar energy acquisition interval, and is set according to other actual conditions such as detection requirements.
The light transmittance threshold is set according to the light transmittance of the solar panel and other practical situations such as the practical requirement on the light transmittance of the solar panel, and will not be described here.
In step S2, solar energy conversion efficiency information is collected, and the influence of low solar energy conversion efficiency on the solar intelligent street lamp is various, wherein the low solar energy conversion efficiency means that the solar cell panel cannot fully utilize solar energy, so that generated electric energy is insufficient; this can lead to the solar intelligent street lamp not obtaining enough energy supply at night, possibly leading to unstable operation of the street lamp, frequent extinction or shortened operation time; the low solar energy conversion efficiency means that the solar panel cannot effectively utilize solar energy resources.
The photoelectric conversion efficiency is calculated, and is the ratio of the output electric power of a unit area to the incident solar power, wherein the photoelectric conversion efficiency is the ratio of the solar battery to convert the solar light into electric energy. The higher the photoelectric conversion efficiency, the higher the energy conversion efficiency of the solar cell.
Notably, the photoelectric conversion efficiency is generally expressed in terms of unit area, so that the performance of solar cells of different sizes and types can be better compared; for example, the photoelectric conversion efficiency of solar panels of different sizes can be directly compared under the same illumination condition, regardless of their actual area; therefore, a unit area is a common standard to represent the photoelectric conversion efficiency of a solar cell.
The output electric power refers to the power of electric energy output by the solar cell panel in an operating state, and the incident solar power refers to the power of solar light irradiated onto the solar cell panel. These two parameters are measured and obtained.
The output electric power may be calculated by measuring the output voltage and the output current of the solar panel. The method comprises the following specific steps:
measuring the output voltage of the solar panel by using a voltmeter, and recording as V (unit: volt); measuring the output current of the solar panel by using an ammeter, and recording as I (unit: ampere); the output electric power P can be calculated by the following formula: p=v×i.
Incident solar power refers to the total power of solar light impinging on the solar panel. Obtained by specialized solar measurement devices, common devices include solar radiometers or solar illuminometers.
The solar radiometer can directly measure the total radiant energy of sunlight irradiated on the solar panel and then convert the total radiant energy into power; the solar illuminometer can measure the irradiance of sunlight in unit area, so that the incident sunlight power is obtained through the product of the area and the irradiance.
In the solar energy acquisition interval, the solar energy acquisition interval is uniformly arranged according to the actual monitoring requirementEach photoelectric conversion efficiency monitoring point corresponds to one calculated photoelectric conversion efficiency,/one>And numbering the photoelectric conversion efficiency corresponding to the photoelectric conversion efficiency monitoring point in the solar energy acquisition interval by taking the photoelectric conversion efficiency monitoring point as a positive integer.
Calculating a photoelectric conversion efficiency average value in a solar energy acquisition interval; the expression is as follows:the lower the average value of the photoelectric conversion efficiency, the lower the photoelectric conversion efficiency of the solar panel.
Analysis of photoelectric conversion efficiency in solar energyThe stability in the interval is obtained, and the stable change coefficient of the photoelectric conversion efficiency is calculated, wherein the expression is as follows:。
wherein ,for the number of photoelectric conversion efficiency corresponding to the photoelectric conversion efficiency monitoring point in the solar energy acquisition interval, +.>Is the average value of photoelectric conversion efficiency; />The photoelectric conversion efficiency stable change coefficient is +.>Photoelectric conversion efficiency of the solar cell and the solar cell in the solar energy acquisition region>And photoelectric conversion efficiency.
The greater the stable change coefficient of the photoelectric conversion efficiency, the poorer the stability of the photoelectric conversion efficiency in the solar energy acquisition interval, which means that the greater the fluctuation degree of the photoelectric conversion efficiency of the solar cell in the solar energy acquisition interval, namely, the higher the variability of the photoelectric conversion efficiency. The solar energy intelligent street lamp has the advantages that the energy conversion efficiency of the solar cell under different illumination conditions is greatly changed, the stability is poor, the uncertainty of energy output is caused, and the stable illumination and energy supply of the solar intelligent street lamp are affected.
In step S3, the light transmission information and the solar energy conversion efficiency information of the solar panel are comprehensively analyzed, the solar energy conversion performance of the solar intelligent street lamp is evaluated, the running state of the solar intelligent street lamp can be monitored in real time, and the control strategy of the solar intelligent street lamp can be supported.
Carrying out normalization processing on the comprehensive light transmittance, the average value of the photoelectric conversion efficiency and the stable change coefficient of the photoelectric conversion efficiency through an edge computing gateway of the solar intelligent street lamp to calculate a light conversion comprehensive performance evaluation coefficient; for example, the present application may calculate the light conversion comprehensive performance evaluation coefficient using the following formula:
； wherein ,/>Evaluating coefficients for light conversion comprehensive performance; />Respectively, the preset proportionality coefficient of the comprehensive light transmittance, the average value of the photoelectric conversion efficiency and the stable change coefficient of the photoelectric conversion efficiency, +.>Greater than 0->Less than 0.
Through the comprehensive performance evaluation coefficient of light conversion, the running state of the solar intelligent street lamp is monitored in real time, so that the normal running of the solar intelligent street lamp is ensured.
The larger the light conversion comprehensive performance evaluation coefficient is, the worse the running state of the solar intelligent street lamp is.
Setting a first performance evaluation threshold and a second performance evaluation threshold, wherein the first performance evaluation threshold is smaller than the second performance evaluation threshold; the first performance evaluation threshold and the second performance evaluation threshold are set by a person skilled in the art according to the magnitude of the light conversion comprehensive performance evaluation coefficient and the actual conditions such as the requirement standard of the solar energy conversion process of the solar intelligent street lamp in the technical field of the art, and are not described herein.
Comparing the light conversion comprehensive performance evaluation coefficient with a first performance evaluation threshold value and a second performance evaluation threshold value, and judging the running state of the solar intelligent street lamp:
when the light conversion comprehensive performance evaluation coefficient is smaller than the first performance evaluation threshold value, a better-operation signal is generated, and at the moment, the operation state of the intelligent solar street lamp is better, so that the normal solar energy acquisition and the solar energy photoelectric conversion can be ensured, and no measures are required at the moment.
