[0036] The safety protection unit is used to protect the charging pile street lamp body from electrical overload, lightning strike and surge, overheating and battery overcharge, over discharge and other potential threats. The specific process is as follows:

[0037] See also Figure 5As shown, the electrical overload protection and overheating protection are detected, and the current, voltage and temperature in each unit of the corresponding sensor are detected; if the current, voltage and temperature data are collected in the solar power generation unit, they are marked as solar power generation electrical thermal data; if the current, voltage and temperature data are collected in the mains power supply unit, they are marked as mains power gas thermal data; if the current, voltage and temperature data are collected in the energy storage unit, they are marked as energy storage electrical thermal data; and so on; the lighting electrical thermal data, power supply electrical thermal data and charging electrical thermal data are obtained, and they are numbered and distinguished. The Yangfa electrical thermal data, the city power gas thermal data, the energy storage electrical thermal data, the lighting electrical thermal data, the power supply electrical thermal data and the charging electrical thermal data are numbered DR1, DR2, DR3, DR4, DR5 and DR6 respectively; if the collected DRn is DR1, the current size L1, the voltage size V1 and the temperature size R1 in the acquisition unit and the corresponding preset weight factors and the corresponding threshold values ​​are obtained, and the corresponding preset weight factors are L'1, V'1 and R'1 respectively, and the corresponding threshold values ​​are L1y, V1y and R1y respectively; n = 1, 2, 3, 4, 5, 6; and the collected DRn is DR1. The DRn and DRn of the set each correspond to a preset weight factor and a threshold value, and are substituted into the three-dimensional coordinate system to obtain the DRn electrical thermal model. The preset weight factors corresponding to DRn are substituted into the three-dimensional coordinate system X and Y axes to obtain the corresponding plane areas according to a certain ratio, and the corresponding plane areas do not overlap, and then the area of ​​the corresponding plane area is calculated; Ln, Vn and Rn in DRn are substituted into the Z axis according to a certain ratio to obtain LZn, VZn and RZn, and they are multiplied by the area of ​​the corresponding plane area to obtain the corresponding volume, and the corresponding number of the corresponding volume is converted into The value is compared with the corresponding threshold value in DRn; if the corresponding value of the current Ln corresponding to the volume is greater than the threshold value Lny, a current Ln overload signal is generated, and the controller immediately triggers an overload protection device, such as a circuit breaker or a fuse, to quickly cut off the circuit to prevent overheating or equipment damage; if the corresponding value of the voltage Vn corresponding to the volume is greater than the threshold value Vny, a voltage Vn overload signal is generated, and the controller immediately triggers the overload protection device; if the corresponding value of the temperature Rn corresponding to the volume is greater than the threshold value Rny, a temperature Rn overheat signal is generated, and active cooling measures (such as reducing LED brightness and charging power) are initiated;

[0038] Similarly, for safety protection against lightning strikes and surges, lightning activities are continuously monitored directly through lightning protection devices or surge protectors (such as lightning rods). When an instantaneous high voltage exceeding the corresponding threshold is detected, it is determined to be a lightning strike or surge, and a lightning protection signal is generated. The lightning arrester or surge protector performs the corresponding operation within nanoseconds. For safety protection against battery overcharge and over-discharge, the battery management module monitors the battery voltage, current and temperature in real time through the corresponding sensors. When the real-time monitored battery voltage exceeds the safety range (overcharge or over-discharge), a battery overcharge or over-discharge abnormality signal is generated, and the charging or discharging current is immediately limited, or the charging or discharging process is completely stopped.

[0039] The intelligent power supply management unit is used to obtain the charging pile street lamp data of the charging pile street lamp for analysis and management; the charging pile street lamp data includes charging and discharging data, environmental data and energy management data, among which the charging and discharging data includes the number of charging and discharging times, charging time, discharging time, discharging efficiency, charging efficiency, charging power and discharging power, etc., and the environmental data includes light intensity, temperature, humidity, wind speed, rainfall, sunrise and sunset time and seasonal changes, etc.; the energy management data includes power supply voltage and power supply current, etc.;

[0040] The charging and discharging is analyzed.

[0041] Analyze the environment. The specific process is as follows: Analyze the light intensity and lighting demand: obtain the real-time light intensity It, and substitute the obtained light intensity It into the preset street light brightness formula B(t): B(t)=f(It(t))=Bmax-k×It(t) Output the street light brightness value Bt; Bmax is the maximum brightness of the street light, k is the adjustment coefficient, which is set according to actual needs; match the street light brightness value Bt with the lighting brightness range of several preset charging pile street lights. If the street light brightness value Bt belongs to the lighting range of several preset charging pile street lights, If the charging pile street lamp is in a certain interval in the brightness interval, the brightness of the charging pile street lamp is controlled to be consistent with the brightness in the corresponding interval; and considering that environmental factors such as high temperature, low temperature, high humidity, and strong wind will affect the charging efficiency and battery performance, the relationship between these environmental factors and the charging efficiency (ηc) or the discharging efficiency (ηd) is analyzed by establishing a regression model: ηow=ηo0+α×(w-w0) Output the charging and discharging efficiency ηow after the influence of temperature, o=c or d; ηc0 is the charging and discharging efficiency at the reference temperature, w0 is the reference temperature, and α is the temperature coefficient;

[0042] Analyze energy management, obtain the fluctuation of urban power supply voltage and power supply current, and evaluate the urban power supply stability of the power grid; first calculate the mean and variance of the obtained power supply voltage and power supply current to obtain the power supply voltage mean Vj, power supply current mean Ij and power supply voltage variance σ 2 V , supply current σ 2 I Variance; then by calculating the maximum and minimum values ​​of the supply voltage and current, the voltage fluctuation range ΔV and current fluctuation range ΔI are obtained, and the formula Output voltage fluctuation value Vw, similarly, through the formula Output current fluctuation value Iw, where Vs and Is are the supply voltage and supply current respectively, and a1, a2, a3 and a4 are preset weight factors;

[0043] The voltage fluctuation value Vw and the current fluctuation value Iw are matched with their respective corresponding preset fluctuation intervals. If both the voltage fluctuation value Vw and the current fluctuation value Iw belong to their respective preset fluctuation intervals, a fluctuation abnormality signal is generated, and power supply and charging are stopped immediately; if one of the voltage fluctuation value Vw and the current fluctuation value Iw belongs to their respective preset fluctuation intervals, the lighting control unit and the charging pile unit are powered by the energy storage unit; specifically: if the energy storage unit power is interval one (the energy storage unit power is interval one (100%-90%), interval two (89%-60%), interval three (59%-30%) and interval four (29%-1%)), the lighting control unit and the charging pile unit are powered directly by the energy storage unit; if the energy storage unit power is interval two, the AC power supply unit and The energy storage unit supplies power to the lighting control unit and the charging pile unit; if the power level of the energy storage unit is interval three, the mains power supply unit and the solar power generation unit charge the energy storage unit, and the energy storage unit supplies power to the lighting control unit and the charging pile unit; if the power level of the energy storage unit is interval four, the charging efficiency from the mains power supply unit and the solar power generation unit to the energy storage unit is calculated as follows: the total charging efficiency value XC is output by the formula XC=η1×κ1+η2×κ2-η5×κ3-η6×κ4, if XC>0, the energy storage unit supplies power to the lighting control unit and the charging pile unit, otherwise, if XC≦0, XC is added with η5×κ3 to obtain a total charging efficiency value of -XC1; when XC1>0, the energy storage unit supplies power to the charging pile unit; when XC1≦0, the energy storage unit stops supplying power.
