Description
Technical Field
The invention relates to the technical field of solar panel assembly matching equipment and application methods, in particular to a system and a method for detecting a solar panel assembly and a solar elevation angle.
Background
The solar panel assembly is an rare green energy source due to environmental protection and energy conservation, and the application of the solar panel assembly is more and more extensive. In order to ensure a good power generation effect, the existing solar panel assembly is provided with a system for tracking the illumination of the sun. At present, a light control subsystem and a time control subsystem are generally combined in a sun tracking illumination system to realize sun tracking control. In the light control subsystem control mode, the tracking of the solar altitude angle is carried out through the mode of light sense probe, in brief, drive the synchronous rotation of light sense probe when just rotating solar cell panel subassembly through the motor, detect simultaneously whether the light intensity of photosensitive device received in the light sense probe has reached the maximum value, if received light intensity has reached the maximum value, then stop rotating battery pack to realize the maximize of battery pack's light reception intensity and receive. In practical situations, when sunlight is well illuminated, the tracking function is realized by detecting the sunlight intensity by using the light sensing probe without any problem. However, when the sky suddenly drifts over a cloud, the light sensing probe cannot acquire correct data, so that the tracking solar illumination system is triggered to rotate the solar panel assembly and the receiver continuously through the motor to drive the light sensing probe to rotate and search the position of the sun, as long as the clouds of the solar panel assembly and the receiver are shielded and are not scattered, the tracking solar illumination system can continuously start a tracking control process, all tracking operations are in vain, only the power consumption of the tracking solar illumination system is increased, and meanwhile, the situation also occurs in rainy days, so that the mode has a great defect.
In the prior art, in order to solve the problem that the tracking of the sun position is invalid because the solar panel assembly and the light sensing probe are shielded by clouds or in rainy days, a time control subsystem is introduced on the basis that the light sensing probe is adopted to track the sun position in the existing sun tracking illumination system. Specifically, the time control subsystem calculates the solar altitude of each time node when the solar panel assembly is installed and a real sun appears according to the longitude and latitude coordinates of the earth of the installation place of the solar panel assembly according to the research result of modern astronomy, so that when the tracking of the light sensing probe fails, the solar altitude is calculated at a certain time interval, then the tracking solar illumination system sets the position of the solar panel assembly (the angle between the solar panel assembly and the sun) according to the calculated solar altitude, once the cloud of the solar panel assembly is shielded, the position of the light sensing probe is close to the position of the real solar altitude, the light sensing probe can detect that the cloud has scattered, and data is acquired again to enable the tracking solar illumination system to enter a normal working state.
In practical situations, a combination method of the light control subsystem and the time control subsystem solves the problem that the defects of the cloud shading and the pure light control tracking mode in rainy days cannot be solved. That is, in rainy days, the time control function can not stop working, because once the working is stopped, in case the weather turns fine, because the position of the light sensing probe can not receive the sunlight, the light control function of the light control subsystem can not be recovered to operate again. The time control subsystem can not stop working, that is, if the weather is continuous, the motors of all the time control subsystems also need to be kept in a working state, if thousands of solar panel assemblies and the motors of the time control subsystems matched with the solar panel assemblies run, a large amount of electric energy needs to be consumed, and at the moment, all the consumed electric energy has no economic benefit, and all the solar panel assemblies cannot output the electric energy because of no irradiation of sunlight.

The particular camera assemblies employed in the present invention all have imaging dimensions, such as a CCD 1/2.5 inch camera, with a diagonal of 1/2.5 inches and a rectangular aspect ratio of 4: 3. The calculation process is as follows: setting the length of an angular line for imaging the camera as D; setting the length of the camera imaging as L; setting the width of the camera as W; then there is D2＝L2+W2，Since W is 3/4L, then D2＝L2+(3/4L)2＝L2+0.752XL2After transformation, the following formula can be obtained: l is2＝D2/(1+0.752) Then L2＝(25.4/2.5)2/1.5625＝66.064384(mm2) And L ═ 8.128 (mm); W8.128X 0.75 6.096 (mm).

As shown in fig. 1, 2, 3 and 4, step B: after the camera assembly is powered on for the first time, the camera image magnification of the camera assembly is set, in the setting process, firstly, the sunlight irradiation condition is ensured to be in a good state when the camera image magnification is set, the camera magnification self-calibration module is adopted to measure and calculate the width value of the stand column shadow according to the stand column shadow image obtained by the image data preprocessing module, and as shown in fig. 2, the stand column BC can project a clear shadow image on the ground glass F. As shown in fig. 4, a schematic diagram of a shadow image is shown, where the width value W indicates that the actual manufactured size of the pillar is a certain value, and where the width value W 'indicates that the camera image magnification factor f is W'/W.
As shown in fig. 1, 2, 3 and 4, step C: when the running time of the system reaches the sunset mountain, the camera assembly enters a dormant state, and when the system time of the camera assembly reaches the rising time of the sun on the next day, the camera assembly is awakened. Step D: the height angle of the sun is calculated in real time through a program arranged in a camera module, the camera module can be awakened at the sunrise time every day, then an image data preprocessing module controls a camera to take pictures according to a specific time interval, a shadow image of a stand column BC (figure 3) can be obtained after the image data measuring and processing module processes the shadow image, the length L of a top slim rod shadow can be calculated through the image data measuring and processing module, the actual shadow length value of the stand column is represented by L', and the stand column shadow length value can be calculated through the following formula: l' ═ L × f.
As shown in fig. 1, 2, 3 and 4, step E: the elevation angle of the sun is calculated by an image data measuring and processing module and a camera amplification factor self-calibration module which are arranged in the camera assembly; as shown in fig. 1, the following can be expressed by the formula: the value of the angle A is obtained by the angle A (CB/AB), the actual height of the column is set to be H, and then: the elevation angle of the sun is arctan (H/L). Step F: the camera assembly synchronously transmits the solar altitude angle data obtained through real-time calculation to the sun tracking illumination system, a basis is provided for the sun tracking illumination system of all the solar panel assemblies to track the altitude angle of the sun, and the motor of the sun tracking illumination system controls the solar panel to align to the altitude angle of the sun based on the synchronous solar altitude angle data. And G, the application software of the camera assembly inquires internal clock data of the camera assembly, and if the time reaches the sunset time, the camera assembly enters a dormant state. And G, if no time reaches the sunset time, repeating the processes from the step D to the step G.
