Step S11: When the current charging current of the solar charging board does not match the comparison charging current, adjust the position of the solar charging board according to a plurality of adjustment position information.

It should be noted that the executor of this application is a camera, the camera has a solar charging board, and the camera is also installed with a control program of the solar charging board. When the camera executes the control program of the solar charging board, the steps of the method for controlling the solar charging board are realized. The solar panel can be installed on the camera, or at a certain distance from the camera, connected by wire or wirelessly.

The method of this application is used for real-time control of the solar panel of the camera. Because the sunlight is real-time, the charging current that needs to be obtained is also a real-time current—the current charging current.

When the current charging current is smaller than the comparison charging current, and the gap between them is less than or equal to the preset gap (for example, 10%, set by the user based on demand), the current charging current matches the comparison charging current, or, the current charging current is higher than the comparison charging If the current is large, the current charging current matches the comparison charging current; when the current charging current is smaller than the comparison charging current, and their gap is greater than a preset gap (for example, 10%), the current charging current does not match the comparison charging current.

Adjusting the position of the solar charging panel according to the plurality of adjustment position information refers to adjusting the solar battery panel to the positions corresponding to the plurality of adjustment position information.

Wherein, when the current charging current of the solar charging board does not match the comparison charging current, before the step of adjusting the position of the solar charging board according to a plurality of adjustment position information, the method includes: acquiring the current The current time corresponding to the charging current and the geographic location information of the camera; according to the current time and the geographic location information, the corresponding comparison charging current is obtained in the preset current library, and the preset current library includes different time Charging current corresponding to different geographic location information; according to the current time and the geographic location information, obtain a plurality of corresponding adjusted location information in a preset location library, the preset location library includes different times and different geographic locations The location information corresponding to the information.

The current time includes time (clock) and date (year, month, day). Geographic location information can be longitude and latitude information. Usually, a longitude and latitude information represents a geographic location; the preset current library includes different geographic location information, and a geographic location information is in Different times (including time and date, for example, a time is 12 o'clock on October 8, 2021) correspond to different charging currents. Similarly, the preset location library includes different geographic location information, and a geographic location information corresponds to different multiple Adjust location information.

Usually, all corresponding charging currents (all charging currents corresponding to the geographical location information identical to the geographic location information in step S11) are determined in the preset current library according to the geographic location information, and then the corresponding charging currents are determined according to the current time. The comparison charging current (the charging current corresponding to the time in the preset database that matches the current time is the comparison charging current, and the matching refers to the same date and time in previous years, for example, October 12 last year and October this year The 12th matches, or a time close to the current time, such as the same moment yesterday, etc.).

Similarly, usually, according to the geographic location information in the preset location library, determine all the corresponding location information (all the location information corresponding to the geographic location information that is exactly the same as the geographic location information in step S11), and then according to the current time, Determine the corresponding multiple adjustment position information (the multiple position information corresponding to the time matching the current time in the preset database is the multiple adjustment position information, and the matching refers to the same date and time in previous years, such as October last year The 12th matches October 12th of this year, or something close to the current time, such as the same moment yesterday, etc.). Wherein, the position information of the solar battery panel in the present application refers to pitch angle information and roll angle information of the solar battery panel.

Specifically, according to the current time and the geographical location information, before the step of obtaining the corresponding comparison charging current in the preset current library, the method further includes: obtaining a plurality of preset charging currents of the solar charging panel. Set charging time, multiple preset location information sets and multiple preset geographic location information, one preset geographic location information corresponds to multiple preset charging times, one preset charging time corresponds to one preset location information set, each location The preset location information set includes different preset location information; when each preset charging time corresponding to each preset geographic location information arrives, according to the corresponding preset location information set, charge the solar charging panel Perform position adjustment; for each preset position information corresponding to each preset charging time, collect a corresponding preset charging current to obtain a preset charging current set corresponding to each preset charging time; A preset charging current set corresponding to each of the preset charging times, to obtain a target charging current corresponding to each of the preset charging times; according to a plurality of the preset geographic location information, a plurality of the preset charging times and A plurality of target charging currents corresponding to a plurality of preset charging times of each preset geographic location information is used to obtain the preset current library.

Wherein, before the step of acquiring multiple preset charging times, multiple preset location information sets and multiple preset geographic location information of the solar charging panel, the method further includes: acquiring multiple preset Geographic location information, one piece of preset geographic location information includes a piece of longitude and latitude information; according to a plurality of said longitude and latitude information, determine a plurality of said preset charging times corresponding to each of said preset geographic location information; According to the latitude and longitude information, the sun angle information corresponding to each preset charging time is obtained; according to the sun angle information corresponding to each preset charging time, the corresponding solar angle information of each preset charging time is obtained. Multiple preset location information sets for .

Users can set different geographic locations for the camera to work based on requirements, and the geographic location is represented by latitude and longitude information. According to each latitude and longitude information, determine the effective sunshine period of the geographic location corresponding to the longitude and latitude information, and determine a plurality of preset charging times (which may involve all effective sunshine periods) based on the effective sunshine period. The longitude and latitude information determines the sun angle information (including the sun's altitude angle and azimuth angle) of the geographical location, and then based on the sun angle information, determines the multiple position information where the solar panel can work under each preset charging time— —Constitute a preset position information set (including multiple pitch angle information and multiple roll angle information, one pitch angle information and one roll angle information constitute one preset position information).

For example, the four quantities of month, day, hour and minute are respectively expressed as Y, R, S and F, and longitude, longitude and minute and year are respectively expressed as JD, JF and NF; the formula for calculating the solar altitude angle (h⊙) is: (sinh⊙=sinδsinφ+cosδcosφcosτ), δ is the solar declination angle, φ is the local geographic latitude, τ is the solar hour angle at that time, the value of φ is not difficult to obtain, and once determined, it will not change. The only thing that needs to be explained is the calculation of the solar hour angle, the calculation formula is: (τ=(S⊙+F⊙/60-12)×15°), here, the symbols of hour S and minute F are marked with ⊙ , indicating true solar time.

In order to obtain the true solar time from Beijing time, two steps are required: First, change Beijing time into local time: (Sd: Sd=S+{F-[120°-(JD+JF/60)]×4}/ 60), 120° is the standard longitude of Beijing time, multiplying by 4 is to convert the angle into time, that is, each degree is equivalent to 4 minutes, and dividing by 60 is to convert minutes into hours; secondly, to correct the time difference, that is: (S⊙=Sd +Et/60), here it should be pointed out that the hour angle is based on solar noon as 0 o'clock, clockwise (afternoon) is positive, and vice versa is negative.

The calculation formula of solar azimuth (A) is: (cosA=(sinh⊙sinφ－sinδ)/cosh⊙cosφ).

It can be understood that this is just an example of a calculation method for the sun's altitude angle and the sun's azimuth angle, and users can make adaptive modifications based on requirements to obtain other calculation methods.

For each preset geographic location information, it involves multiple preset charging times. When a preset charging time arrives, use all the preset location information in the preset location information set corresponding to the preset charging time to The position of the solar charging panel is adjusted, and each collected position information corresponds to a preset charging current, and multiple preset charging currents corresponding to a preset position information set involved in a preset charging time constitute a preset charging current set; Several charging currents with the highest charging currents may be determined from the set of preset charging currents, and then averaged to obtain the target charging current corresponding to the preset charging time. For a preset geographic location information, obtain multiple target charging currents corresponding to multiple preset charging times involved in the geographic location information, traverse all preset geographic location information, and obtain all preset charging currents corresponding to all preset geographic location information The target charging current of the preset charging time is obtained, and then the preset current library is obtained. The preset current library includes target charging currents corresponding to each preset geographic location information at different preset charging times. A target charging current is a charging current in the preset current library. The charging current obtained in the preset current library in step S11 refers to the comparison charging current (in order to facilitate the distinction, the word comparison is added before the charging current).

Similarly, before the step of obtaining a plurality of corresponding adjusted position information in the preset position library according to the current time and the geographic location information, the method further includes: at each preset charging time In the corresponding preset charging current set, a plurality of primary charging currents are determined; in the preset position information set corresponding to each preset charging time, a plurality of primary charging currents corresponding to each preset charging time are determined A plurality of primary location information corresponding to the charging current; according to a plurality of the preset geographic location information, a plurality of the preset charging times, and each of the preset charging times corresponding to each of the preset geographic location information multiple primary location information to obtain the preset location library.

For each preset geographic location information, it involves multiple preset charging times. When a preset charging time arrives, use all the preset location information in the preset location information set corresponding to the preset charging time to The position of the solar charging panel is adjusted, and each collected position information corresponds to a preset charging current, and multiple preset charging currents corresponding to a preset position information set involved in a preset charging time constitute a preset charging current set; Several charging currents with the highest charging currents can be determined in the set of preset charging currents, and these several highest charging currents are multiple primary charging currents, and each primary charging current involves a preset charging current in the preset charging time. Assuming that the location information is concentrated, it corresponds to one primary location information, so it corresponds to multiple primary location information. For a preset geographic location information, obtain a plurality of primary location information corresponding to a plurality of preset charging times involved in the geographic location information, traverse all preset geographic location information, and obtain all The primary location information of the preset charging time is obtained, and then the preset location library is obtained. The preset location database includes a plurality of primary location information corresponding to each preset geographic location information at different preset charging times. Each primary location information refers to a piece of location information in the preset location library. The plurality of position information obtained in the preset position library in step S11 refers to a plurality of adjusted position information (in order to facilitate the distinction, the word "adjustment" is added before the position information).

Step S12: collecting the adjusted charging current of the solar charging board at each of the adjusted position information.

Step S13: Using the plurality of adjustment currents, determine the selected adjustment position information among the plurality of adjustment position information.

Step S14: Using the selected adjustment position information to control the solar charging panel.

Similar to the above, when the solar charging panel is in an adjusted position information, a charging current is collected—that is, the adjusted charging current. Then determine the largest one among the multiple adjustment currents as the selected adjustment current, and then determine an adjustment position information corresponding to the selected adjustment current as the selected adjustment position information. Finally, using the plurality of adjustment currents, the selected adjustment position information is determined from the plurality of adjustment position information.

Further, the solar charging board includes an inertial measurement unit; the step of using the selected adjustment position information to control the solar charging board includes: obtaining the inertial measurement unit according to the selected adjustment position information Acceleration information of the measurement unit; according to the acceleration information, the solar charging board is controlled. Wherein, the adjusted position information also includes pitch angle information and roll angle information.

Specifically, the acceleration information is expressed as

Among them, a _x , a _y and a _z are the components of the acceleration information a ^B in the three directions of x, y and z axes respectively (coordinate axes refer to the coordinate axes of the world coordinate system), then the acceleration information can be obtained according to formula 1, Formula One is:

Among them, θ is the pitch angle information in the selected adjustment position information,

Adjust the roll angle information in the position information for the selection.

Further, the solar charging board further includes a gyroscope; before the step of controlling the solar charging board according to the acceleration information, the method further includes: performing a filtering operation on the acceleration information to obtain the The resulting acceleration information of the inertial measurement unit and the angular acceleration information of the gyroscope; the step of using the acceleration information to control the solar charging panel includes: according to the resulting acceleration information and the angular acceleration information to control the solar charging board.

Among them, the acceleration information is used as the long-term reference of the static horizontal plane (that is, the vertical direction), and its data is fused with the angle change of the gyroscope to realize the dynamic tilt angle response without drift. This classic accelerometer + gyroscope sensor fusion is the origin of the term vertical gyro in aircraft. We usually apply the Kalman filter to filter the acceleration information to obtain the resulting acceleration information of the inertial measurement unit and the angular acceleration information of the gyroscope, wherein the resulting acceleration information and the angular acceleration information are filtered The accuracy obtained by the operation is relatively high, and redundant and invalid impurity information is not included, so that the control accuracy of the solar charging panel is also relatively high.

In the existing solar camera, the position of the solar panel is fixed, but the position of the sun is variable, so that the solar panel cannot correspond to the position of the sun, and the charging current of the solar panel is small, and the charging effect of the camera is relatively small. Difference. Using the method of the present application, according to multiple adjustment position information, the final selected adjustment position information can be better adapted to the position of the sun, and the charging current of the solar panel is increased, thereby improving the charging effect of the camera.
