Detailed Description
The present application will be described in further detail with reference to the accompanying drawings and examples.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
The embodiment of the application provides a control method of a solar power supply system, as shown in fig. 1. The control method comprises the following steps:
and step 101, acquiring basic control information of the solar power supply system.
Here, as a device for realizing photovoltaic power generation, a solar power supply system is generally composed of a solar panel, a control system, and an electric storage system. In sunny days and in the presence of sunlight, the solar cell panel converts the light energy of sunlight into electric energy; in the case of no sunlight or overcast weather, the control system is powered by the electric power storage system.
Illustratively, the underlying control information includes one or more of the following: time information, weather information, season information.
It should be noted that, the solar power supply system of the embodiment of the application can be provided with a networking system, and can acquire local time, weather and seasons based on the networking system according to a preset acquisition period; the solar power supply system can be provided with an APP control system, local time, weather and seasons input by a user can be recorded through the APP control system, and the APP control system can remind the user to update historical environment information according to a preset period; the networking system and the APP control system can be matched for use, for example, if a user forgets to update the historical information, the networking system can directly acquire local time, weather and seasons, or the networking system can directly acquire the local time, weather and seasons and the like, and then the user can also adjust the weather information according to actual conditions.
Step 102, determining a detection period of the illumination intensity of sunlight based on the environmental information and the current operation mode of the solar power supply system.
Here, the solar power supply system is provided with a photosensitive element, and the photosensitive element detects the illumination intensity of sunlight and is used for judging whether the current illumination intensity of the sunlight meets the power supply requirement of the solar power supply system.
Illustratively, the modes of operation of the solar power system include: a power mode and a standby mode. In the power supply mode, the solar power supply system converts light energy provided by sunlight into electric energy, and detects illumination intensity of the sunlight based on a detection period. In the standby mode, the solar power supply system detects the illumination intensity of sunlight based only on the detection period.
It can be understood that when the current illumination intensity of sunlight cannot meet the power supply requirement of the solar power supply system, the solar power supply system is in a standby mode and is powered by the power storage system, and at the moment, the solar power supply system only maintains the periodic illumination intensity detection function so as to ensure the cruising ability of the solar power supply system.
Step 103, detecting the illumination intensity of sunlight based on the detection period, and generating a detection result.
And 104, controlling the operation mode of the solar power supply system based on the detection result.
Based on the basic control information, the current operation condition of the solar power supply system can be determined, and then the average illumination intensity of sunlight under the operation condition can be judged. Here, the basic control information for specifying the operation condition may be one of time information, weather information, season information, and the like, or may be a combination of a plurality of pieces of information among the time information, weather information, season information, and the like.
Illustratively, the operating conditions of the power-over-power system include a first operating condition and a second operating condition, the average illumination intensity of sunlight under the first operating condition being less than the average illumination intensity of sunlight under the second operating condition.
It should be noted that, the average illumination intensity of the sunlight under the first operating condition and/or the second operating condition is obtained based on the illumination intensity detection result under the corresponding operating condition of the history accumulation.
In an application example of the present application, the solar power supply system may directly determine the current operation condition based on the single information in the acquired basic control information. For example, the solar power supply system acquires time information of 1:00 am, and based on the time information, the current operation condition can be directly determined to belong to a first operation condition with weaker average illumination intensity of sunlight; for another example, the solar power supply system acquires weather information of haze weather, and the first operation condition of the current operation condition can be directly determined based on the weather information.
In one application example of the present application, the solar power supply system may determine the current operation condition based on a plurality of information combinations in the acquired basic control information. For example, the solar power supply system acquires time information of 11:00 am and weather information of sunny days, and the solar power supply system cannot determine the current operation condition from single time information or day level information, but based on the combination of the time information and the weather information, it may be determined that the current operation condition belongs to a second operation condition with strong average illumination intensity of sunlight.
In an application example of the present application, the solar power supply system acquires time information of 6:00 pm, weather information of cloudy days and season information of winter, and based on a combination of the time information, the weather information and the season information, it may be determined that the current operation condition belongs to the first operation condition.
Here, the correspondence rule between the basic control information and the operation condition is not particularly limited in the embodiment of the present application.
Here, the solar power supply system according to the embodiment of the application may be provided with a determining model for determining the current operation condition of the solar power supply system, the determining model determines the current operation condition based on the basic control information and the corresponding rule base, and trains the determining model and updates the rule base based on the historically accumulated basic control information and the sunlight illumination intensity detection information, so as to improve the accuracy of the operation condition judgment.
Further, in one example of application of the present application, the solar power supply system may acquire and update the latest version of the determination model based on the networked system.
It should be noted that, the first operating condition and the second operating condition are distinguished based on the average illumination intensity of the corresponding sunlight, and the specific distinguishing method is not specifically limited in the embodiment of the present application. In an application example of the present application, the first operation condition and the second operation condition may be distinguished based on a set illumination intensity threshold, where an average illumination intensity of sunlight under the first operation condition is greater than or equal to the set illumination intensity threshold, and an average illumination intensity of sunlight under the second operation condition is less than the set illumination intensity threshold, where the set illumination intensity threshold is an illumination intensity of sunlight corresponding to a power supply requirement of the solar power supply system. Illustratively, the detection period of the illumination intensity of the sunlight includes a first period and a second period. Wherein the first period is greater than the second period.
Illustratively, determining a detection period of the illumination intensity of the sunlight based on the base control information and the current operating mode of the solar power supply system includes:
If the acquired basic control information corresponds to the first operation condition and the current operation mode is the standby mode, the detection period is determined to be a first period.
If the acquired basic control information corresponds to the first operation condition and the current operation mode is the power supply mode, the detection period is determined to be a second period.
And if the acquired basic control information corresponds to the second operation condition, determining the detection period as a second period.
It can be appreciated that under the second operation condition, the average illumination intensity of the sunlight is strong, and the power supply requirement of the solar power supply system is easily satisfied, and at this time, the solar power supply system is operated in the power supply mode or the standby mode, and the illumination intensity of the sunlight is periodically and frequently detected in a shorter second period.
It will be appreciated that under the first operating condition, the average illumination intensity of the sunlight is weak, and it is difficult to meet the power supply requirement of the solar power supply system, if the solar power supply system is operated in the standby mode, the power storage system supplies power at this time, so as to reduce the static loss of the solar power supply system, and under the first operating condition, where it is difficult to meet the power supply requirement of the solar power supply system, the solar power supply system periodically detects the illumination intensity of the sunlight with a longer first period.
It can be appreciated that if the solar power supply system is operated in the power supply mode, the output power of the solar power supply system may satisfy the operation of the solar power supply system, and at this time, the solar power supply system periodically and frequently detects the illumination intensity of the sunlight in a shorter second period.
It can be understood that the solar power supply system of the embodiment of the application acquires the current environmental information such as time, season, weather and the like in real time, prolongs the detection period of the illumination intensity of sunlight under severe running conditions, reduces the static energy consumption of the solar power supply system in a standby mode, and improves the cruising ability of the solar power supply system.
Illustratively, controlling the operation mode of the solar power supply system based on the detection result includes:
If the detection result is greater than or equal to the set illumination intensity threshold value, controlling the solar power supply system to operate in a power supply mode;
and if the detection result is smaller than the set illumination intensity threshold value, controlling the solar power supply system to operate in a standby mode.
It can be understood that the solar power supply system is controlled to operate in the power supply mode based on that the illumination intensity of sunlight reaches the illumination intensity threshold value, and the output power of the solar power supply system at least can meet the power consumption when the solar power supply system operates in the power supply mode.
The embodiment of the application also provides a control method of the solar power supply system, as shown in fig. 2. The control method comprises the following steps:
Step 201, in a power supply mode, obtaining a first current value representing an output current value of a solar panel of a solar power supply system.
Step 202, controlling the rotation position of the solar panel based on the first current value.
Illustratively, controlling the rotational position of the solar panel based on the first current value includes:
Determining a solar movement direction based on the detection result;
controlling the solar cell panel to rotate in a first travel range along the solar movement direction;
determining a first position corresponding to the solar panel based on a peak value of a first current value when the solar panel rotates in a first travel range;
And controlling the solar panel to rotate to the first position.
It should be noted that, the number of the photosensitive elements is at least two, and the solar power supply system can determine the movement direction of the sun according to the change of the detection results of the at least two photosensitive elements.
When the sunlight is vertically irradiated onto the upper surface of the solar cell panel, the sunlight is at the maximum illumination intensity and the output current of the solar cell panel is at the maximum.
It can be understood that as the sun moves, the incident angle of the sunlight with the upper surface of the solar panel changes, the output current of the solar panel changes accordingly, and the solar panel rotates along the movement direction of the sun, so that the output current can be increased as much as possible.
It should be noted that the solar panel may rotate in both the clockwise and counterclockwise directions within the maximum allowable travel range. Further, the maximum allowable travel range may be +40° to-40 °, where-40 ° is 40 ° of rotation of the solar panel in a counterclockwise direction and 40 ° is 40 ° of rotation of the solar panel in a clockwise direction.
It should be noted that the first range of travel is smaller, and the solar panel may be fine-tuned within the first range of travel.
In one application example of the present application, the first stroke range may be set as a set rotation angle range in the solar movement direction, for example, the first stroke range is set as a rotation range of 0 ° to 5 ° in the solar movement direction.
It can be appreciated that when the first current value decreases, the solar panel performs fine adjustment within the first travel range, at which time the first current value should be increased and then decreased, and the solar power supply system determines the position (i.e., the first position) of the corresponding solar panel when the first current value is maximum, and controls the solar panel to rotate to the first position.
Illustratively, controlling the rotational position of the solar panel based on the first current value further comprises:
Controlling the solar panel to rotate within a maximum allowable travel range based on a preset third period;
determining a second position corresponding to the solar panel based on a peak value of the first current value when the solar panel rotates in the maximum allowable travel range;
And controlling the solar panel to rotate to the second position.
Here, the third period is a preset correction period, and the solar power supply system corrects the rotation position of the solar panel based on the third period, so as to ensure that the output current of the solar panel corresponding to the corrected rotation position is maximum.
Preferably, the third period may be 15 minutes.
It can be understood that according to the control method of the solar power supply system provided by the embodiment of the application, the solar panel can rotate in real time based on the change of the output current, and the correction operation within the maximum allowable travel range is performed once within the set time period, so that the sunlight is ensured to vertically irradiate on the upper surface of the solar panel, the maximum output current of the solar panel is ensured, and the efficiency of the solar power supply system is improved.
In an application example of the present application, if the acquired environmental information is determined to be the first environmental information and the current operation mode is the power supply mode, the solar panel is controlled to rotate in the first travel range along the solar motion direction based on the preset fourth period.
It can be appreciated that under the first environmental condition, the output current of the solar panel is smaller, and the rotation position of the solar panel is controlled in a fixed period, so that the energy consumption of the solar power supply system can be reduced, and the output current of the solar panel charges the electric storage system as much as possible.
In an application example of the present application, an automatic light-circulating method of a solar power supply system is provided, as shown in fig. 3. The automatic light-circulating method comprises the following steps:
step 301, controlling the solar power system to operate in a standby mode.
Here, the solar power supply system is in a standby mode operation, and the solar panel is in a preset initial position.
In step 302, the first photosensitive element and the second photosensitive element detect the illumination intensity of sunlight, and generate a detection result.
Here, the first photosensitive element and the second photosensitive element periodically detect the illumination intensity of sunlight based on the first period or the second period.
Step 303, judging whether the detection result is greater than or equal to a set illumination intensity threshold, if so, executing step 304; if not, step 301 is performed.
Here, the detection result includes a first detection result and a second detection result, wherein the first detection result is detected by the first photosensitive element, and the second detection result is detected by the second photosensitive element.
