[0036] Please refer to Figure 1 As shown, a circuit control system for a vehicle charging pile street lamp includes: a database, a feature extraction module, and a circuit control module;

[0037] It is set that each vehicle charging pile street lamp corresponds to a lighting area. It should be noted that the lighting area is specifically set by those skilled in the art according to the actual installation situation; the environmental information refers to the environmental information within the lighting area of the vehicle charging pile street lamp;

[0038] The database communicates with each vehicle charging pile street lamp and the sensors mounted on the vehicle charging pile street lamp to obtain environmental information, energy storage information, and vehicle information; wherein the environmental information includes environmental brightness, pedestrian flow, and vehicle flow; the energy storage information includes the charge load of each vehicle charging pile street lamp; the vehicle information includes the SOC of the vehicle (the charge state of the battery, that is, the percentage of the current stored power of the battery relative to its maximum capacity);

[0039] The feature extraction module analyzes based on the environmental information, energy storage information, and vehicle information respectively to extract control feature parameters; specifically:

[0040] Illumination feature analysis:

[0041] Retrieve the environmental information corresponding to each acquisition moment, where the environmental information includes environmental brightness, vehicle flow, and pedestrian flow, and record them as Lj, Cj, and Rj respectively, where j = 1, 2, 3... J, J is a positive integer, J represents the total number of acquisition moments, and j represents any one of the acquisition moment serial numbers; use the set formula Calculations are performed to obtain the lighting-related value LRj, where a1, a2, and a3 are respectively set proportionality coefficients; from the formula, it can be seen that the greater the traffic flow and the greater the pedestrian flow, it indicates that the street lamp of the electric vehicle charging pile needs to increase the brightness to provide a better lighting environment; if the ambient brightness in the lighting area of the street lamp of the electric vehicle charging pile is lower, while the traffic flow and pedestrian flow are greater; or the ambient brightness in the lighting area is higher, while the traffic flow and pedestrian flow are smaller; both indicate that the lighting brightness in the photo area at this time does not match the lighting demand; then the lighting-related value is smaller; correspondingly, when the ambient brightness in the lighting area of the street lamp of the electric vehicle charging pile corresponds to the pedestrian flow and traffic flow, the lighting-related value is greater;

[0042] Taking time as the abscissa and the lighting-related value as the ordinate, a two-dimensional rectangular coordinate system is constructed. The lighting-related values are plotted on the coordinate axis according to their corresponding acquisition times to obtain each lighting point. A smooth curve is used to connect each lighting point in sequence to obtain the curve relationship diagram of the lighting-related value of the street lamp of the electric vehicle charging pile changing with time; at the lighting point, a tangent to the curve is made, and the tangent expression is obtained by data fitting. The derivative of the tangent expression is calculated to obtain the lighting derivative denoted as Mj; when the lighting derivative is greater than zero, it indicates that at this lighting point, the lighting-related value shows an increasing trend. When the lighting derivative is less than zero, it indicates that at this lighting point, the lighting-related value shows a decreasing trend; the lighting derivatives greater than zero are summed to obtain the lighting positive correlation degree denoted as F1, and the lighting derivatives less than zero are summed and the absolute value is taken to calculate the lighting negative correlation degree denoted as F2. Using the set formula Calculations are performed to obtain the lighting adjustment index FM, where b1, b2, and b3 are respectively the set proportionality coefficients, is the average lighting derivative of each lighting point; from the formula, it can be seen that when the overall decreasing trend of the lighting-related value is greater, it indicates that the ambient brightness in the lighting area does not match the traffic flow and pedestrian flow in its area, then the lighting adjustment index is greater; when the lighting derivative fluctuates more, it indicates that there are more situations where the traffic flow, pedestrian flow, and ambient brightness in the lighting area do not match, then the lighting adjustment index is greater;

[0043] Analysis of charging characteristics:

[0044] Retrieve the energy storage information at each acquisition time. The energy storage information includes the charge load of each street lamp of the electric vehicle charging pile and is denoted as Pij, where i = 1, 2, 3...I, and I represents the total number of street lamps of the electric vehicle charging pile in the same load area, and i represents the serial number of any one street lamp of the electric vehicle charging pile; it should be noted that the charge load refers to the lighting load and charging load of each street lamp of the electric vehicle charging pile, etc.;

[0045] Compare and analyze the charge load of each vehicle charging pile street lamp with the set load range. When the charge load is greater than the upper limit of the set load range, it indicates that the charge load of the vehicle charging pile street lamp at this moment is relatively large, and then accumulate a high load point; when the charge load is within the set load range, then accumulate a medium load point; when the charge load is less than the lower limit of the set load range, then accumulate a low load point; respectively count the number of high load points, medium load points and low load points in the same grid load area, and record them as U1j, U2j and U3j respectively; use the set formula to calculate the grid load value Ug at each acquisition moment, where g1, g2, and g3 are respectively the set proportionality coefficients, and g1 > g2 > g3 > 0;

[0046] Construct a two-dimensional rectangular coordinate system with time as the abscissa and the grid load value as the ordinate. Plot the grid load values at their corresponding acquisition moments on the coordinate axis to obtain each load point. Connect each load point in sequence with a smooth curve to obtain a curve graph of the grid load value changing with time; at each load point, make a tangent to the curve, use data fitting to obtain the tangent expression, and perform derivative calculation on the tangent expression to obtain the load derivative corresponding to each load point, denoted as Zj; sum the load derivatives greater than zero to obtain the load increase degree, denoted as D1, and sum and take the absolute value of the load derivatives less than zero to obtain the load decrease degree, denoted as D2; use the set formula to calculate the load state index DZ, where d1, d2, and d3 are respectively the set proportionality coefficients, is the average value of the load derivatives of each load point; it can be seen from the formula that when the grid load value is larger and the overall increasing trend of the grid load is greater, the load state index is larger; when the grid load value is more unstable, the load state index is larger;

[0047] Record the lighting adjustment index and the load state index as control characteristic parameters, and send them to the circuit control module;

[0048] By respectively analyzing the lighting and charging characteristics of the environmental information, energy storage information and vehicle information to obtain the control characteristic parameters, where the control characteristic parameters include the lighting adjustment index and the load state index. The lighting adjustment index comprehensively considers the environmental brightness, traffic flow and pedestrian flow, analyzes the influence of these factors on the lighting demand, and can accurately evaluate the demand change of the lighting state, so as to guide the dynamic adjustment of the lighting intensity; the load state index evaluates the stability and intensity of the charge load of the charging pile street lamp, reflects the change trend of the load, and helps to optimize the load management; therefore, the control characteristic parameters can accurately evaluate the lighting state and charging load state of the vehicle charging pile street lamp, and provide data support for the dynamic adjustment of the lighting and charging strategies of the vehicle charging pile street lamp.

[0049] The circuit control module performs circuit control for lighting and charging based on the received control characteristic parameters to optimize energy use and improve energy utilization rate. Specifically:

[0050] Lighting control:

[0051] Compare and analyze the lighting regulation index with the set lighting regulation threshold. When the lighting adjustment index is greater than the set lighting adjustment threshold, it indicates that the environmental brightness in the lighting area does not match the traffic flow (vehicle flow and pedestrian flow) in the area. Then, perform lighting regulation on the street lights of the electric vehicle charging pile. The specific steps of its lighting regulation are as follows:

[0052] Retrieve the vehicle flow and pedestrian flow corresponding to each acquisition moment in the lighting area of the street lights of the electric vehicle charging pile, and calculate their respective means to obtain the average vehicle flow and average pedestrian flow, and denote them as and ; Use the set formula to calculate the brightness adjustment value CR, where f1 and f2 are respectively the set proportionality coefficients, and β is the set brightness conversion coefficient; It can be seen from the formula that when the vehicle flow and pedestrian flow in the lighting area of the street lights of the electric vehicle charging pile are larger, it indicates that the lighting demand in the lighting area is relatively high, and the corresponding brightness adjustment value is larger; Adjust the brightness of the street lights of the electric vehicle charging pile according to the brightness adjustment value, which can perform intelligent lighting control based on real-time data to meet different environmental requirements and energy-saving requirements;

[0053] Charging control:

[0054] Set several SOC intervals, and each interval corresponds to a charging weakening coefficient; It should be noted that in the high SOC state, the battery is close to full charge. Continuing to charge at high power may cause overcharging, affecting the chemical stability of the battery and reducing the service life of the battery; In addition, high-power charging generates more heat, and reducing the charging power at high SOC can reduce the temperature rise, thus avoiding damage to the battery caused by overheating; Therefore, the larger the upper and lower limits of the SOC interval, the smaller the corresponding weakening coefficient; For example: there are SOC intervals [90%, 100%), [80%, 70%), [70%, 50%) and [50%, 0%) respectively. The weakening coefficient corresponding to the interval [90%, 100%) is 0.6; The weakening coefficient corresponding to the interval [80%, 70%) is 0.7; The weakening coefficient corresponding to the interval [70%, 50%) is 0.8; The weakening coefficient corresponding to the interval [50%, 0%) is 1 (i.e., no weakening is required);

[0055] Retrieve the SOC of the charging vehicle corresponding to the street lights of the electric vehicle charging pile at the current moment, and compare it with all the set SOC intervals to match the corresponding weakening coefficient denoted as k; Pass the weakening coefficient and the load status index through the set formula Perform calculation and analysis to obtain the charging guidance power SD, where γ is the set charging power conversion coefficient. It can be seen from the formula that when the SOC is larger, the charging guidance power decreases appropriately; when the load status index is larger, it indicates that there is a greater grid burden on the grid, and the charging power is smaller. Thus, the charging guidance power corresponding to each vehicle charging pile street lamp can be obtained, and the vehicle charging power is controlled accordingly, so that vehicle charging can be completed as quickly as possible while ensuring safety, improving energy utilization, and realizing intelligent control of vehicle charging;

[0056] Dynamically adjust the brightness in the lighting area and the charging power of the vehicle charging pile street lamp by controlling the characteristic parameters, so that the light brightness in the lighting area can meet the actual needs under different environments, avoid over-illumination, and thus save energy; at the same time, adjust the charging power according to the SOC interval of the battery and the load status index, make the charging process more efficient, avoid overcharging, reduce the grid burden, and thus optimize energy utilization; realize the optimization of energy utilization and the intelligent control of vehicle charging pile street lamps.

[0057] The above are only embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
