Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic power supply for small base stations, and specifically, to a method, device, equipment and medium for photovoltaic power supply for 5G small base stations. Background Art

[0002] 5G's three super capabilities, large bandwidth, low latency, and massive connections, have a huge impact on people's living habits and social models. In the future, these three super capabilities will also make 5G technology widely used in various fields such as industry, agriculture, transportation, mining, and smart cities. However, due to the high frequency of 5G signals, the signal attenuation is large and the coverage range is small. Therefore, if you want to promote 5G technology and achieve full coverage, you need to deploy a large number of 5G small base stations. However, densely deploying 5G small base stations will face the problem of power supply difficulties, especially for the following situations:

[0003] ① Scenic spots: Scenic spots have always been the key coverage target of operators and one of the manifestations of a good network reputation. The internal scenic spots and roads in the scenic spots are affected by the surrounding terrain and environment, which often leads to the inability of surrounding base stations to cover them. 5G small base stations are light in weight and small in size. They can be deployed on poles and lamp poles to cover a section of road or a scenic spot in the scenic spot. However, power supply problems make the deployment of 5G small base stations more difficult.

[0004] ② Remote rural areas: In remote rural areas, especially in mountainous rural areas, if macro base stations are deployed, the capacity is low, the investment cost is high, and the efficiency is low. The above problems can be effectively solved by deploying 5G small base stations in high-lying areas for thin coverage, but the power supply of 5G small base stations in remote mountainous areas or rural areas is very difficult.

[0005] ③ High-rise residential buildings: In residential scenarios, especially high-rise residential scenarios, the depth of coverage is insufficient due to the dense buildings. The traditional indoor construction method requires large investment, long payback period, and often has many low-efficiency sites. By deploying 5G small base stations at appropriate locations within the community, the buildings can be covered, macro-micro collaboration can be achieved, and indoor and outdoor integrated coverage can be achieved. However, the wiring in the community damages the environment, and underground wiring requires digging up the road surface and vegetation, etc., and power supply is also a problem.

[0049] Based on this, the embodiments of the present application provide a 5G small base station photovoltaic power supply method, device, equipment and medium, which are described below through embodiments.

[0050] Example 1

[0051] To facilitate understanding of this embodiment, a 5G small base station photovoltaic power supply method disclosed in the embodiment of this application is first introduced in detail. Figure 1 A flow chart of a 5G small base station photovoltaic power supply method shown in the figure, a 5G small base station photovoltaic power supply method provided in the present application is applied to a photovoltaic power supply system, the photovoltaic power supply system includes a tracking module, a chasing module, a power supply module, a control module, a photovoltaic panel and an energy storage battery, the method includes:

[0052] S101, the tracking module calculates the power generation value of the photovoltaic panel based on the power generation voltage value and the corresponding current value of the photovoltaic panel monitored in real time, so as to obtain the charging power value based on the power generation value;

[0053] S102, the light-chasing module detects the light on both sides of the photovoltaic panel and the angle between the light and the sun in real time based on the charging power value to obtain corresponding real-time light signals and real-time angle signals, and outputs the real-time light signals and the real-time angle signals to the control module;

[0054] S103, the control module obtains an angle adjustment instruction based on the real-time light signal and the real-time angle signal, so as to control the photovoltaic panel to be in an optimal position relationship with the sun based on the angle adjustment instruction;

[0055] S104. The control module charges the energy storage battery based on the optimal position relationship and the charging power, and converts the direct current output by the energy storage battery into alternating current based on the power supply module for use by the 5G small base station.

[0056] In the present application, the photovoltaic power supply system uses photovoltaic panels to generate electricity to power the energy storage battery, wherein the number of photovoltaic panels is not limited and can be set according to the specific application scenario.

[0057] In step S101, the tracking module has a built-in collection unit, and the collection unit is based on the real-time monitored power generation voltage value and the corresponding current value of the photovoltaic panel, wherein the power generation voltage value collected by the collection unit can be collected based on the voltage sensor, and the current value collected by the collection unit can be collected based on the current sensor, or based on other methods to collect the current value corresponding to the power generation voltage value of the photovoltaic panel, so as to calculate the power generation power value P of the photovoltaic panel based on the power generation voltage value U and the corresponding current value I, that is, based on the formula P=UI, the power generation power value P is obtained by multiplying the power generation voltage value U and the corresponding current value I, so as to obtain the charging power value based on the power generation power value, and the charging power value is used for charging the energy storage battery, so the energy storage battery is charged based on the charging power value.

[0058] In the specific implementation process of step S101, there is an embodiment: Figure 2 As shown, the charging power value of the energy storage battery powered by the photovoltaic panel based on the generated power value includes:

[0059] S1011, the tracking module calculates a future power generation value within a future time period, and compares the future power generation value with the power generation value to obtain a first comparison result;

[0060] S1012. The tracking module determines a charging power value provided to the energy storage battery at a future moment based on the first comparison result.

[0061] In steps S1011-S1012, the tracking module is based on the generated voltage value U at time i. i The current value I at the corresponding moment i Calculate the power generation value P at time i i , the power generation values ​​P at multiple historical moments that have been obtained are summarized to determine the trend and law of the power generation value P, and based on the power generation value P i The trend of the future power generation value P in the future time period is calculated i+1 , and compare the power generation value P i With the future power value P i+1 A first comparison result is obtained, wherein the first comparison result includes the power generation value P i >The future power generation value P i+1 , or the power generation value P i <The future power generation value P i+1 , or the power generation value P i = the future power generation value P i+1 , and if the first comparison result is the generated power value P i >The future power generation value P i+1 , or the power generation value P i = the future power generation value P i+1 When the future power generation value P i+1 Adjustment is made, then the future power generation value P i+1 That is, the charging power value provided to the energy storage battery at the future time, and if the first comparison result is the power generation value P i <The future power generation value P i+1 , then call the hill climbing algorithm to calculate the future power value P i+1 Adjustments are made to keep the charging power value at the maximum at all times, so that the energy storage battery can be charged with maximum power.

[0062] In the specific implementation process of step S1012, there is an embodiment in which the tracking module determines the charging power value provided to the energy storage battery at a future moment based on the first comparison result, including:

[0063] S10121, the tracking module calculates the voltage difference between the future power generation voltage value and the power generation voltage value based on the first comparison result;

[0064] S10122. The tracking module adjusts the future power generation voltage value based on the voltage difference, so as to calculate and obtain the charging power value based on the future power generation voltage value.

[0065] In steps S10121-S10122, the tracking module determines that the first comparison result is the generated power value P i <The future power generation value P i+1 , then the tracking module again determines the future power generation voltage value V at time i+1 based on the hill climbing algorithm i+1 The generated voltage value V at time i i If the future power generation voltage value V at time i+1 is i+1 The generated voltage value V at time i i If they are not equal, the tracking module calculates the future power generation voltage value V at time i+1 i+1 The generated voltage value V at time i i The voltage difference △V between them is used to calculate the future power generation voltage value V at the future time based on the voltage difference △V. i+1 Adjustment is made based on the future generated voltage value V i+1 The future power generation value at time i+1 is calculated with the corresponding current value, and the future power generation power is used as the charging power value at the future time, so as to charge the energy storage battery based on the charging power value.

[0066] In step S102, the light-chasing module makes a judgment based on the charging power value. If the power generation efficiency calculated by the power generation value corresponding to the charging power value meets the conversion condition, the light-chasing module does not act. The conversion condition is that the power generation efficiency of the photovoltaic panel is the maximum. When the power generation efficiency does not meet the conversion condition, the light-chasing module detects the light on both sides of the photovoltaic panel and the angle between the photovoltaic panel and the sun in real time to obtain corresponding real-time light signals and real-time angle signals. The light is the sun's light. The light-chasing module detects the real-time light signal and the real-time angle signal based on a photoelectric detector, that is, photoelectric detectors are respectively arranged on the left and right sides of the photovoltaic panel to respectively detect the distances between the left and right sides to the light to obtain real-time light signals, and two photoelectric detectors are arranged above the photovoltaic panel to detect the vertical angle between the photovoltaic panel and the sun to obtain a real-time angle signal, and output the real-time light signal and the real-time angle signal to the control module. There is a communication method between the light-chasing module and the control module to realize the transmission of the real-time light signal and the real-time angle signal to the control module.

[0067] In step S103, the control module makes a judgment based on the real-time light signal and the real-time angle signal. If the position of the photovoltaic panel corresponding to the real-time light signal and the real-time angle signal needs to be adjusted, the control module generates an angle adjustment instruction, and the angle adjustment instruction includes the distance the photovoltaic panel needs to move, the direction of movement, and the angle to be adjusted. The light-chasing module also includes an adjustment mechanism, and the adjustment mechanism includes a driving chip and a motor, that is, the driving chip drives the motor to adjust the position of the photovoltaic panel based on the angle adjustment instruction, and adjusts the photovoltaic panel to the optimal position relationship with the sun, and the optimal position relationship is that the angle between the photovoltaic panel and the sun is a vertical angle and the photovoltaic panel can follow the light to the maximum extent.

[0068] In the specific implementation process of step S103, there is an embodiment in which the control module obtains an angle adjustment instruction based on the real-time light signal and the real-time angle signal, and controls the photovoltaic panel to be in an optimal position relationship with the sun based on the angle adjustment instruction, including:

[0069] S1031, the control module determines whether the position of the light and the photovoltaic panel meets the preset adjustment condition based on the real-time light signal;

[0070] S1032: If yes, the control module generates the angle adjustment instruction to adjust the position of the photovoltaic panel.

[0071] In steps S1031-S1032, the control module determines whether the position of the light and the photovoltaic panel meets the preset adjustment conditions based on the real-time light signal. The preset adjustment conditions are that the photovoltaic panel cannot follow the light, or the angle between the photovoltaic panel and the sun is not a vertical angle, that is, 90 degrees. If the real-time light signal meets the preset adjustment conditions, or the real-time angle signal meets the preset adjustment conditions, or the real-time light signal and the real-time angle signal meet the preset adjustment conditions at the same time, the control module obtains an angle adjustment instruction. If neither the real-time angle signal nor the real-time light signal meets the preset adjustment conditions, the control module does not adjust the position of the photovoltaic panel and allows the photovoltaic panel to charge the energy storage battery.

[0072] In the specific implementation process of step S1032, there is an embodiment: if yes, the control module generates the angle adjustment instruction to adjust the position of the photovoltaic panel, including:

[0073] S103211, the control module calculates the difference angle between the real-time angle value corresponding to the real-time angle signal and the threshold angle;

[0074] S103212. The control module adjusts the photovoltaic panel according to the difference angle based on the angle adjustment instruction.

[0075] In steps S103211-S103212, the control module converts the real-time angle signal into the real-time angle value of the photovoltaic panel, and calculates the difference angle between the real-time angle value corresponding to the real-time angle signal and the threshold angle. In order to maximize the power generation efficiency of the photovoltaic panel, the photovoltaic panel and the sun are in a vertical relationship, that is, 90 degrees. The driving chip drives the motor to adjust the photovoltaic panel based on the difference angle, and obtains the angle between the photoelectric detector on the photovoltaic panel and the sun in real time until the photovoltaic panel and the sun are at a vertical angle, so as to maximize the power generation efficiency of the photovoltaic panel.

[0076] In the specific implementation process of step S1032, there is an embodiment: if yes, the control module generates the angle adjustment instruction to adjust the position of the photovoltaic panel, including:

[0077] S103221, the control module determines based on the real-time light signal to obtain the angle adjustment direction of the photovoltaic panel;

[0078] S103222. The control module controls the photovoltaic panel to move based on the angle adjustment direction.

[0079] In steps S10322-S103222, the control module makes a judgment based on the real-time light signal to obtain the angle adjustment direction of the photovoltaic panel, where the angle adjustment direction refers to the direction in which the photovoltaic panel can follow the sun. The control module controls the movement of the photovoltaic panel based on the angle adjustment direction, and the driving chip drives the motor to adjust the photovoltaic panel based on the angle adjustment direction, and obtains in real time whether the photoelectric detector on the photovoltaic panel can detect the light emitted by the sun in real time, until the photovoltaic panel can follow the light to the utmost, so as to maximize the power generation efficiency of the photovoltaic panel.

[0080] For example, let the light detectors on both sides of the photovoltaic panel be A and B respectively. When A detects that the light is moving away from the photovoltaic panel, the control module controls the driver chip to make the motor rotate forward, causing the photovoltaic panel to rotate left to follow the light; the photodetector B is used to detect the situation where the light on the right side is moving away from the photovoltaic panel. When B detects that the light is moving away from the photovoltaic panel, the control module controls the driver chip to reverse the motor, causing the photovoltaic panel to rotate right to follow the light.

[0081] S104, the control module charges the energy storage battery based on the optimal position relationship and the charging power, that is, at this time the photovoltaic panel has the highest power generation efficiency and can also charge the energy storage battery at the maximum power. When the control module detects that the 5G small base station needs power supply, the control module converts the direct current output by the energy storage battery into alternating current based on the power supply module, and then supplies the 5G small base station with alternating current, thereby realizing efficient and environmentally friendly power supply for the 5G small base station.

[0082] In the specific implementation process of step S104, there is an embodiment: Figure 3 As shown, the power supply module includes an inverter unit;

[0083] The converting of the direct current output by the energy storage battery into alternating current based on the power supply module for use by the 5G small base station includes:

[0084] S1041, the control module generates a corresponding complementary current based on the direct current, and outputs the complementary current to the inverter unit;

[0085] S1042: After receiving the complementary current, the inverter unit converts the direct current and the complementary current into alternating current.

[0086] In steps S1041-S1042, the inverter unit includes an isolation circuit, a drive circuit, a full-bridge circuit, a filter boost circuit, and a protection circuit. The control module outputs a PWM wave complementary to the DC power output by the energy storage battery. The PWM wave is connected to an optocoupler isolation circuit. The optocoupler is unidirectionally transmitted and can realize unidirectional transmission of signals, so that the input end and the output end are completely electrically isolated. The output signal has no effect on the input end and has strong anti-interference ability; the output signal of the optocoupler isolation circuit is transmitted to the drive circuit composed of IR2101. IR2101 is a dual-channel, gate-driven, high-voltage and high-speed power driver. The device adopts a highly integrated level conversion technology, which simplifies the control requirements of the logic circuit on the power device and improves the drive The reliability of the driving circuit is improved. At the same time, the upper tube adopts an external bootstrap capacitor to power on, which greatly reduces the number of driving power supplies compared with other IC drivers. The driving circuit is composed of two IR2101 and its external circuit. Each IR2101 outputs two control signals to control the on and off of the two MOS tubes of the bridge arm respectively, and finally converts the DC power of the energy storage battery into a square wave signal. After the transformer boost and LC filtering circuit, the sinusoidal AC power is output. The current sampling resistor converts the current signal into a voltage signal and then compares the voltage value with the preset voltage value through the comparator. When the current exceeds the preset value, a stop signal is output and the stop signal is transmitted to the controller, then the control module stops outputting the PWM wave, which plays a protective role.

[0090] The output module 402 is used for the light-chasing module to respectively detect the light on both sides of the photovoltaic panel and the angle between the light and the sun in real time based on the charging power value to obtain corresponding real-time light signals and real-time angle signals, and output the real-time light signals and the real-time angle signals to the control module;
