In the prior art, solar energy is generally converted into electric energy through a solar panel and stored in the open air, and the electric energy stored in the solar panel is used for providing energy for a street lamp in a specified time period, so that the illumination effect is realized.
However, the electric energy stored by solar panels each day is greatly affected by weather conditions, and particularly in areas where weather changes are large, the electric energy stored by solar panels often cannot meet the requirement of full-range illumination in a prescribed period of time.
The application provides a current regulation method and device for supplying power by using a solar panel, which can automatically regulate the power supply current of the solar panel according to the stored electric quantity of the solar panel, thereby meeting the requirement of realizing whole-course illumination in a specified time period as far as possible.
A schematic flow chart of a current regulation method using solar panels for power supply according to an embodiment of the present application is described below, and in particular, reference is made to fig. 1.
S101, determining the endurance time of the lamp tube according to the stored electric quantity information of the solar panel and the normal current of the lamp tube.
Before each specified time period, the current regulating device can acquire electric quantity information in an energy storage battery connected with the solar panel, and then determines the endurance time of the lamp tube according to the electric quantity information in the energy storage battery and the current of the lamp tube in normal operation, wherein the endurance time is the time when the lamp tube can perform effective illumination.
Specifically, the current adjusting device is respectively connected with the energy storage battery and the lighting lamp tube through a circuit, before each specified lighting time period, the current automatic control device reads the electric quantity information of the energy storage battery and calculates the duration time of the lamp tube when working with normal current, and the calculation formula of the duration time can be as follows:
wherein Q represents the stored electricity quantity of the energy storage battery, and the unit is coulomb (C), I 0 The normal current of the lamp tube is expressed in amperes (A), t is expressed as the duration of the lamp tube, and the unit is seconds (S).
For example, if the stored power of the energy storage battery of the solar panel is 9000C and the normal current of the lamp tube is 0.5A, the duration of the lamp tube is 18000S according to the above formula, i.e. the duration of the lamp tube is 5 hours.
It should be noted that, the preset time period is a time period set by a user and required to be illuminated by light, and the division of the time period may be adjusted according to the requirement of the user, which is not limited herein.
S102, judging whether the duration is greater than or equal to a preset duration.
After determining the duration of the lamp tube, the current automatic control device determines whether the duration of the lamp tube is greater than or equal to a preset duration, if the duration of the lamp tube is greater than or equal to the preset duration, the step S107 is entered, otherwise, if the duration of the lamp tube is less than the preset duration, the step S103 is entered, wherein the preset duration is the lighting working time of the lamp tube set by the user.
S103, determining the estimated current under the condition of meeting the preset endurance time.
After judging that the duration of the lamp tube is smaller than the preset duration, the current adjusting device calculates the estimated current which is required to be provided by the current energy storage battery under the condition that the stored electric quantity of the current energy storage battery meets the preset duration, wherein the estimated current is the current which can be provided by the solar panel under the condition that the preset duration of the lamp tube is met.
Specifically, the estimated current calculation formula may be modified according to the endurance time calculation formula in step S101, that is
Wherein Q represents the stored electricity quantity of the energy storage battery, and the unit is coulomb (C), I 1 Representing the estimated current of the lamp tube, the unit is ampere (A), t 0 The preset duration of the lamp tube is indicated in seconds (S).
For example, if the stored power of the energy storage battery of the solar panel is 3600C and the preset duration of the lamp tube is 5 hours, the estimated current of the lamp tube is 0.2A according to the above formula.
S104, judging whether the estimated current is larger than or equal to a preset current threshold value.
After judging that the duration of the lamp tube is less than the preset duration and determining that the estimated current under the condition of meeting the preset duration is met, the current adjusting device judges whether the estimated current is greater than or equal to a preset current threshold, specifically, if the current adjusting device judges that the estimated current is greater than or equal to the preset current threshold, step 105 is entered, otherwise, if the current adjusting device judges that the estimated current is less than the preset current threshold, step 106 is entered.
It will be appreciated that the preset current threshold is the lowest current that the lamp can effectively illuminate, and is generally set by the user according to the actual situation, which is not limited herein.
S105, adjusting the current of the lamp tube according to the estimated current.
After the current adjusting device judges that the estimated current is greater than or equal to the preset current threshold, the current adjusting device controls the current passing through the lamp tube to be equal to the estimated current in a specified lighting time period.
S106, adjusting the current of the lamp tube according to a preset current threshold.
After the current adjusting device judges that the estimated current is smaller than the preset current threshold, the current adjusting device controls the current passing through the lamp tube to be equal to the preset current threshold in a specified lighting time period.
And S107, adjusting the lamp tube current according to the weather information of the next day.
After the current adjusting device judges that the duration of the lamp tube is greater than or equal to the preset duration, the current adjusting device can acquire weather information of the next day and adjust the current passing through the lamp tube in the specified lighting time period according to the weather information of the next day.
Specifically, after the current adjusting device judges that the endurance time of the lamp tube is greater than or equal to the preset endurance time, the current adjusting device sends a weather information acquisition instruction to the terminal device, the terminal device pre-processes weather information of the second weather after receiving the weather information acquisition instruction, and sends the weather information of the pre-processed second day to the current adjusting device, and the current adjusting device determines the current of the lamp tube according to the weather information of the second day.
It is understood that the process of preprocessing the weather information of the second day by the terminal device includes calculating a time proportion of each weather type in the weather information of the second day, and it is understood that the weather information of the second day is estimated, so that the weather information of the second day and the time proportion of each weather type in the weather information of the second day are both predicted values, and there is no exact requirement on the accuracy of the predicted values, which is not limited herein.
The current regulator is connected with the terminal device in a wireless manner, and can send simple instruction information data to the terminal device or receive the information data sent by the terminal device.
It should be further noted that, the terminal device mentioned in the embodiment of the present application is an electronic device having functions of information acquisition, processing and sending, and the electronic device may be a server, a mobile phone, a computer, or other electronic devices having functions of information acquisition, processing and sending, which is not limited herein.
Through the technical scheme provided by the embodiment, when the stored electric quantity of the solar panel does not meet the preset endurance time requirement of lighting of the lamp tube, the current of the most suitable lamp tube is selected according to the stored electric quantity of the current solar panel to prolong the actual endurance time of lighting of the lamp tube, so that the requirement of the lamp tube for realizing whole-course lighting in a specified time period is met as far as possible.
Next, an overall flow of a current regulation method using solar panels for power supply in the embodiment of the present application will be described in detail, with reference to fig. 2.
S201, determining the brightness level of the lamp tube according to the geographical position information of the lamp tube.
Specifically, the current adjusting device may send positioning information of the current adjusting device to the terminal device, and receive geographic position information of the lamp tube generated by the terminal device according to the positioning information, and the current adjusting device determines a brightness level of the lamp tube according to the geographic position information. The geographical position information of the lamp tube comprises road topography and route information of the position of the lamp tube; the positioning information may be GPS positioning information, or other positioning information such as a beidou navigation system, which is not limited herein.
For example, a known current adjusting device receives geographical position information sent from a terminal device after sending positioning information of the current adjusting device to the terminal, and determines that the position of the lamp is flat in terrain according to the geographical position information, but the brightness level of the lamp is selected to be one level in a road section with many curves; if the position of the lamp tube is judged to be the road section with flat terrain and good road according to the geographic position information, the brightness level of the lamp tube is selected to be the second level.
It should be noted that the brightness level of the lamp tube may be divided into a first level, a second level and a third level, and the brightness level of the lamp tube may be adjusted according to the actual situation, which is not limited herein.
It will be appreciated that, in general, the greater the current passing through the lamp, the higher the luminance emitted by the lamp, and the luminance of the lamp can be divided into different luminance levels according to the difference of the luminance of the lamp, where each luminance level corresponds to the normal current of one lamp.
In addition, the current regulating device is connected with a database, and normal currents corresponding to different brightness levels of the lamp tubes are stored in the database.
S202, determining the normal current of the lamp tube according to the brightness level of the lamp tube.
It will be appreciated that, as known from step S201, each brightness level of the lamp corresponds to a normal current of one lamp, and thus, after the brightness level of the lamp is determined, the normal current of the lamp can be determined accordingly.
S203, acquiring the stored electricity quantity information of the solar panel.
The current regulating device is connected with the energy storage battery of the solar panel, and can acquire the electric quantity information stored by the energy storage battery in real time.
S204, receiving preset endurance time and preset current threshold set by a user.
The user can set the preset duration time and the preset current threshold value of the lamp tube according to the actual demand, wherein the preset duration time is the lighting working time of the lamp tube set by the user; the preset current threshold is the lowest current at which the lamp can effectively illuminate.
S205, determining the endurance time of the lamp tube according to the stored electric quantity information of the solar panel and the normal current of the lamp tube.
The present step is the same as step S101, and will not be described here again.
S206, judging whether the duration is greater than or equal to the preset duration.
After determining the duration of the lamp, the current automatic control device determines whether the duration of the lamp is greater than or equal to the preset duration, if the duration of the lamp is greater than or equal to the preset duration, the step S212 is entered, otherwise, if the duration of the lamp is less than the preset duration, the step S207 is entered.
S207, determining the estimated current under the condition that the preset endurance time is met.
This step is the same as step S103 and will not be described here again.
S208, judging whether the estimated current is larger than or equal to a preset current threshold.
After determining that the duration of the lamp is less than the preset duration and determining that the estimated current under the condition of meeting the preset duration, the current adjusting device determines whether the estimated current is greater than or equal to a preset current threshold, specifically, if the current adjusting device determines that the estimated current is greater than or equal to the preset current threshold, step 209 is entered, otherwise, if the current adjusting device determines that the estimated current is less than the preset current threshold, step 210 is entered.
S209, adjusting the current of the lamp tube according to the estimated current.
After the current adjusting device judges that the estimated current is greater than or equal to the preset current threshold, the current adjusting device controls the current passing through the lamp tube to be equal to the estimated current in a specified lighting time period.
S210, adjusting the lamp tube current according to a preset current threshold.
After the current adjusting device judges that the estimated current is smaller than the preset current threshold, the current adjusting device controls the current passing through the lamp tube to be equal to the preset current threshold in a specified lighting time period.
S211, sending second early warning information of insufficient storage electric quantity of the solar panel to the terminal equipment.
After judging that the duration of the lamp tube is smaller than the preset duration and determining the estimated current under the condition of meeting the preset duration, if the current adjusting device judges that the estimated current is smaller than the preset current threshold, the current adjusting device adjusts the current of the lamp tube according to the preset current threshold and then sends second early warning information of insufficient storage electric quantity of the solar panel to the terminal equipment.
S212, judging whether the time proportion of abnormal weather is larger than a preset proportion threshold value according to the weather information of the next day.
Specifically, after the current adjusting device determines that the duration is greater than or equal to the preset duration, the current adjusting device sends a weather information acquisition instruction to the terminal device, and the terminal device performs preprocessing on weather information of a second weather after receiving the weather information acquisition instruction and sends the weather information of the preprocessed second day to the current adjusting device. The automatic adjusting device judges whether the time proportion of abnormal weather is larger than a preset proportion threshold value according to weather information of the next day. If the proportion of time occupied by the abnormal weather is greater than the preset proportion threshold value, step S210 is entered; if the proportion of time occupied by the abnormal weather is less than or equal to the preset proportion threshold, the step S213 is proceeded.
For example, in one embodiment, the preset proportion threshold is known to be 20%, and after the current adjusting device sends a weather information obtaining instruction to the terminal device, the weather information of the next day after the processing is obtained is: and the weather information of the second day indicates that the time proportion of the raining and the clouding is less than a preset proportion threshold value, namely the time proportion of the abnormal weather is less than the preset proportion threshold value.
In another embodiment, the preset proportion threshold is known to be 20%, and after the current adjusting device sends a weather information obtaining instruction to the terminal device, the weather information of the next day after the processing is obtained is: and the sunny day accounts for 20%, the rainy day accounts for 50% and the cloudy day accounts for 30%, and according to the weather information of the second day, the time proportion of the rainy day and the cloudy day is larger than a preset proportion threshold, namely the time proportion of the abnormal weather is smaller than the preset proportion threshold.
It is understood that the process of preprocessing the weather information of the second day by the terminal device includes calculating a time proportion of each weather type in the weather information of the second day, and it is understood that the weather information of the second day is estimated, so that the weather information of the second day and the time proportion of each weather type in the weather information of the second day are both predicted values, and there is no exact requirement on the accuracy of the predicted values, which is not limited herein.
Specifically, the terminal device can obtain weather prediction conditions of the next day through weather prediction software, the weather prediction conditions comprise duration of each weather type in the next day, and the terminal device predicts time proportion occupied by each weather type according to the duration of each weather type in the next day. For example, the terminal device obtains 12:00-18:00 (24 hours) raining, 6:00-12: and on a sunny day, the weather types of the second day comprise raining and sunny days, wherein the time probability of raining is 50 percent, and the time probability of sunny days is 50 percent.
It should be noted that, in the embodiment of the present application, the time proportion occupied by each weather type refers to the time proportion occupied by each weather type in the day, and the range of the day is set according to the local natural law, the areas where the lamps are located are different, and the range of the day may have a difference, which is not limited herein.
S213, regulating the lamp tube current according to the normal current.
After the proportion of the time occupied by the abnormal weather on the next day is less than or equal to the preset proportion threshold value, the current regulating device controls the current passing through the lamp tube to be normal in a specified lighting time period.
S214, opening the lamp tube according to the regulated current in a preset time period.
After the current adjusting device adjusts the current of the lamp tube, the lamp tube is opened according to the adjusted current in a specified time period.
And S215, if the current passing through the lamp tube is always zero in the preset time period, sending first early warning information of lamp tube fault.
Specifically, the current adjusting device detects whether the lamp tube has current passing through the lamp tube in a specified lighting time period in each preset time period, and if the lamp tube has no current passing through the lamp tube all the time, the current adjusting device sends first early warning information of lamp tube faults to the terminal equipment.
It will be appreciated that the absence of current through the lamp for a given illumination period within each preset period is likely to be a failure of the lamp. In addition, the preset time period is generally defaulted to 3 days, and can be adjusted by the user according to actual conditions, which is not limited herein.
