[0032] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the scope of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0033] As shown in Figure 1 A street lamp power supply intelligent control system, comprising a server, a daytime monitoring control module and a night monitoring control module;

[0034] The city is divided into several power supply areas, and there are several street lamps in each power supply area. The server is connected with the sensors carried on the street lamps in each area to obtain the environmental information and street lamp information in the daytime state and the street lamp information in the night state of each area in real time, and stores them;

[0035] The daytime monitoring control module performs real-time monitoring analysis based on the environmental information and the street lamp information to judge the solar power generation state and the energy consumption state of the street lamps in the area, and obtains the power stability index accordingly, specifically:

[0036] Optionally, the environmental information of each collection time in each daytime state is called, wherein the environmental information includes light intensity and temperature, and is recorded as Qj and Tj, wherein j=1, 2, 3…J, J is a positive integer, J is the total number of collection times, and j is any one of the collection times; it should be noted that the light intensity is a main factor directly affecting the power generation efficiency of the solar panel, and the greater the light intensity, the higher the power generation; and the temperature indirectly affects the power generation efficiency of the solar panel, and higher temperature will cause the efficiency of the solar panel to decrease;

[0037] The light information of each collection time in each daytime state is called, which specifically includes solar power generation, battery power, and light consumption, and is recorded as Fj, Dj and Hj; it should be noted that even in the same area, the solar energy receiving amount, temperature and solar power generation of the light at different positions will be different, because some lights will be partially shaded by buildings or billboards or other items (the temperature under direct sunlight will be slightly higher, and the amount of solar energy converted into electrical energy will also be more);

[0038] The model of the solar panel loaded on each light is obtained, and it is set that each model of the solar panel corresponds to an optimal working temperature, and is recorded as ZT; it should be noted that the optimal working of different models of solar panels is different, and is usually about 25°C, and when the temperature exceeds this range, the efficiency will gradually decrease, and the output power of the solar panel may decrease by 0.3% to 0.5% per 1°C increase in temperature; the light intensity, temperature and optimal working temperature are normalized and the values are taken, and the corresponding solar energy value TQj of each collection time is obtained by formulaic calculation and analysis of the values; the specific calculation formula is: Wherein γ1 and γ2 are proportional constants set respectively; as can be seen from the formula, the closer the temperature is to the optimal working temperature of the solar panel, the greater the solar energy value; the greater the light intensity, the greater the solar energy value; and the greater the solar energy value, the more sufficient the solar energy of the environment where the light is located;

[0039] The solar energy value TQj, the solar power generation Fj, the battery power Di and the light consumption Hj (although the light usually does not illuminate during the day, but various sensors are loaded on the modern light, and these sensors still work during the day, so a certain amount of power consumption will be generated) are normalized and the values are taken, and the daytime energy state value N1j is obtained by formulaic calculation and analysis of the values; the specific calculation formula is: Wherein δ1, δ2, δ3, δ4 are respectively set proportional constant, and δ3> δ2> δ1> 1;From the formula, when the daytime state of the street lamp is in the sunlight, the more the power generation, the more the battery storage power, the less the power consumption, which indicates that the storage state of the street lamp for solar energy is better at this time;

[0040] A two-dimensional rectangular coordinate system is constructed with time as the horizontal coordinate and the daytime energy state value as the vertical coordinate, the daytime energy state value is input into the coordinate axis according to its corresponding collection time, and the position of the daytime energy state value in the coordinate axis is recorded as a daytime state point, and a smooth curve is used to connect each daytime state point to obtain a daytime energy state value curve with time variation; Thus, the daytime energy state value curve with time variation under the daytime state can be obtained;

[0041] For the daytime energy state value curve with time variation under the daytime state, a tangent line is drawn at each daytime state point, and the slope of the tangent line is calculated using the least squares method. Thus, the daytime slope at each state point can be obtained. It should be noted that the daytime slope represents the change trend of the daytime energy state value at the state point. When the daytime slope is greater than zero, it indicates that the daytime energy state value at the state point increases. When the daytime slope is less than zero, it indicates that the daytime energy state value at the state point decreases. The daytime energy increase value S1 is calculated by summing the daytime slopes greater than zero, and the daytime energy decrease value S2 is calculated by summing the daytime slopes less than zero and taking the absolute value. The daytime energy state value N1j, the daytime energy increase value S1 and the daytime energy decrease value S2 at each collection time under the daytime state are normalized and their values are taken, and the values are calculated and analyzed according to the formula to obtain the daytime energy index R1 under the daytime state. The specific calculation formula is: Wherein λ1, λ2 are respectively set proportional constant; From the formula, the greater the increasing trend of the daytime energy state value, the smaller the decreasing trend, which indicates that the overall change trend of the daytime energy state value presents an increasing trend, and the greater the daytime energy index; The greater the daytime energy state value at each collection time, the better the environment for the solar panel of the street lamp to fully convert and store solar energy;

[0042] The battery power at the last collection time under the daytime state is retrieved (usually referring to the time when the solar panel of the street lamp can no longer convert solar energy into electrical energy from the environment); When the daytime energy index is greater than the set energy threshold, and the battery power is greater than the set power threshold, the battery power is used to supply power to the lighting of the street lamp, and a night monitoring control signal is generated to the night monitoring control module; Otherwise, the power supply mode of the street lamp is switched to grid power supply;

[0043] By monitoring the environmental information (such as light intensity, temperature) and street lamp information (such as power generation, battery capacity, power consumption) of the street lamps in the region in real time, the solar power generation state and the street lamp power consumption state can be accurately judged, and according to the daytime energy index and the battery capacity, it can be automatically judged whether to use the battery capacity for power supply, otherwise switch to grid power supply, realizing accurate energy state monitoring, dynamic analysis and intelligent switching, improving the stability of the street lamp power supply system, energy utilization efficiency and the use ratio of renewable energy, while reducing energy waste and cost, with significant energy saving and stability improvement effect.

[0044] The night monitoring control module monitors the night power supply of the street lamps in each region using battery capacity for power supply, and judges whether the energy use mode needs to be switched to realize intelligent smooth switching and ensure stable lighting of the street lamps; Specifically:

[0045] The street lamp information under the night state is retrieved, which specifically includes the battery capacity and the street lamp power consumption, and is recorded as D2j and H2j respectively; The battery capacity D2j and the street lamp power consumption H2j are normalized and the values are taken, and the values are calculated and analyzed by formula to obtain the night energy state value N2j under the night state; The calculation formula is: Wherein, α1 and α2 are respectively set proportional constants, according to the formula, when the night state, the more the battery capacity of the street lamp, the smaller the power consumption, which means that at this time, the street lamp uses the battery capacity to provide lighting; Take time as the horizontal coordinate and the night energy state value under the night state as the vertical coordinate to construct a two-dimensional rectangular coordinate system, input the night energy state value according to its corresponding collection time into the coordinate axis, and record the position of the night energy state value in the coordinate axis as the night state point, and connect each night state point in turn with a smooth curve to obtain the relationship diagram of the night energy state value with time; The tangent of the curve at each night state point is drawn, and the slope of the tangent is calculated by the least square method, so that the night slope at each night state point can be obtained; It should be noted that because the street lamp cannot convert solar energy into electric energy under the night state, the battery capacity decreases with the increase of lighting time, the night energy state value decreases with the increase of lighting time, and the night slope decreases; The absolute value of the night slope is recorded as |Kj|;

[0046] The absolute value of the night slope |Kj| is compared with the set change interval. When the absolute value of the night slope is greater than the upper limit of the set change interval, it indicates that the night energy state value presents a large decrease, and then the first team decrease is accumulated once. When the absolute value of the night slope is in the set change interval, then the second team decrease is accumulated once. When the absolute value of the night slope is less than the lower limit of the set change interval, then the third team decrease is accumulated once. The accumulated times of the first team decrease, the second team decrease and the third team decrease are counted respectively, and are recorded as U1, U2 and U3 respectively. The accumulated times of the first team decrease, the second team decrease and the third team decrease and the absolute value of the night slope |Kj| are normalized and the values are taken, and the values are calculated and analyzed by a formula to obtain the night energy change index KU. The specific calculation formula is: Wherein β1, β2 and β3 are the set proportional constants. As can be seen from the formula, the greater the absolute value of the night slope |Kj|, the greater the decreasing trend of the night energy state value, and the greater the possibility that the battery power cannot maintain the continuous lighting of the street lamp.

[0047] The lighting time length of the street lamp providing lighting at the current time of the system is obtained, and is recorded as M1. It should be noted that the total lighting time length of the city street lamp is usually set to 10-12h, and the specific time length can be adjusted by the person skilled in the art according to the actual seasonal needs. The shorter the lighting time length, the more sufficient the battery power should be, otherwise the battery power is difficult to continue to the total lighting time length with the continuous lighting. The total lighting time length set by the street lamp in the current system is obtained, and is recorded as M2.

[0048] The power consumption of the street lamp in the night state is called and summed to obtain the total consumption value X. The total consumption value X, the lighting time length M1 and the total lighting time length M2 are calculated by a formula to obtain the predicted consumption M3. The specific calculation formula is: The battery power at the current time of the system is obtained, and is recorded as D. When the following conditions are met simultaneously, The night continues to use the battery power to supply power for the lighting of the street lamp. Otherwise, the power supply mode of the street lamp is switched to grid power supply. Wherein a is the time length conversion coefficient, and A is the set fixed threshold.

[0049] By monitoring the battery power, power consumption, lighting time and the trend of the night energy state value of the street lamp in the night state in real time, the consumption speed of the battery power and the change of the power supply can be identified, and it can be accurately judged whether the battery power is sufficient to maintain the continuous lighting of the street lamp; when the battery power is insufficient, the system will switch to the power grid power supply in time to ensure the continuity and stability of the street lamp lighting; the risk of excessive discharge of the battery is minimized, thereby prolonging the service life of the battery, and at the same time, the power supply mode of the street lamp lighting can be optimized according to the current energy change and the battery power condition, the frequency of the power grid power supply is reduced, the utilization efficiency of solar energy resources is improved, and the intelligent smooth switching power supply mode is realized.

[0050] The above formulas are obtained by collecting a large amount of data for software simulation and selecting a formula close to the true value, and the coefficients in the formula are set by a person skilled in the art according to the actual situation.

[0051] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that they are within the scope of the present application.

[0052] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
