Referring to fig. 1, a first embodiment of the present invention is:
the invention provides a control method of a light energy street lamp, which comprises the following steps:
step 1, if the current weather of an area where the light energy street lamp is located is rainy weather, obtaining first road information where the light energy street lamp is located;
the method comprises the steps of judging whether the natural illuminance of an area where the light energy street lamp is located is lower than a preset value or not through real-time monitoring data of the distributed natural illuminance, and determining that the current weather of the area where the light energy street lamp is located is rainy if the natural illuminance of the area where the light energy street lamp is located is lower than the preset value.
In the above embodiment, the first road information includes the positioning information of the light energy street lamp, and the specific city and the basic attribute of the road can be obtained through analysis by combining the positioning information with a map system.
Step 2, inquiring a road grade table according to the first road information to obtain a first road grade corresponding to the first road information, wherein the road grade table is configured to store road information and road grades corresponding to the road information one by one;
in the above embodiment, the road grade is mainly divided into three levels, namely, a main road, a secondary road and a branch road, and the road grade corresponding to the road information can be queried through the road grade table only by knowing the road information. This road rank is a coefficient in the subsequent calculation, and corresponds to a weight. If the light energy street lamp is arranged on the main road, the traffic flow is relatively more even at night, and if the light energy street lamp is arranged on the branch road, such as some paths, the traffic flow is generally less.
If the road grade of the first road information is the main road, the corresponding coefficient is 1; if the road grade of the first road information is a secondary road, the corresponding coefficient is 0.8; if the road grade of the first road information is a branch road, the corresponding coefficient is 0.5.

Generally, the reference illumination intensity corresponding to the main trunk is 15lx, the reference illumination intensity corresponding to the sub trunk is 8lx, and the reference illumination intensity corresponding to the branch is 5 lx. However, the dynamic adjustment is performed in combination with the traffic flow, for example, the optical street lamp is located on the main road, the traffic flow in the time period of the main road is 2000, which indicates that the traffic flow is large, according to the following list, the numerical value corresponding to the traffic flow is found to be 1.2, and the above parameters are substituted into the following calculation formula:
calculating a first illumination intensity of 1.2 × 1 × 15(lx) of 18 (lx);
the first illumination intensity is used for controlling the working state of the light energy street lamp in the next time period, however, the illumination intensity in the next time period is larger than the illumination intensity difference in the previous time period, and if the instantaneous illumination change causes phenomena such as dizziness of a driver, the illumination change time length is determined according to the illumination intensity difference corresponding to two adjacent time periods, for example, 20(lx) is adjusted to 10(lx), the change time length of 20 minutes is needed, and 20(lx) is adjusted to 15(lx), the change time length of 10 minutes is needed, so that the larger the illumination intensity value to be adjusted is, the more time is used for changing, and the problem of potential safety hazard caused by the illumination intensity change can be solved.
The method further comprises the following steps: the method comprises the steps of collecting first vehicle flow corresponding to vehicles passing through a first road in the current time period, obtaining first residual electric quantity of a current power supply, and analyzing according to the first road grade, the first vehicle flow and the first residual electric quantity to obtain first illumination intensity and first illumination change duration. On the basis of the technical scheme, the final first illumination intensity and the first illumination change duration are obtained through comprehensive analysis by combining the residual electric quantity of the current power supply, so that the light energy street lamp can work more reasonably.
If the acquired first remaining capacity of the current power supply is lower than a first threshold, the illumination intensity of the light energy street lamp is adjusted to 70% of the first illumination intensity, entering into a power saving mode can be achieved, specifically, whether the remaining capacity is lower than the first threshold is judged, and if yes, the original illumination intensity is adjusted to 70%.
And 4, controlling the working state of the light energy street lamp in the next time period in real time according to the first illumination intensity and the first illumination change duration.
Step 5, if the duration T of the working state of the light energy street lamp reaches half of the first illumination duration T, namely T is more than or equal to T/2, and continuously collecting a second vehicle flow corresponding to the passing vehicles on the first road information within the remaining half of the first illumination duration;
and analyzing according to the first road grade and the second vehicle flow to obtain a second illumination intensity and a second illumination change duration, and taking the second illumination intensity and the second illumination change duration as correction values of the illumination intensity and the illumination change duration in the next time period.
Further, the method also comprises the following steps:
if the difference value between the first illumination intensity obtained by analysis and the illumination intensity of the previous time period is larger than a second threshold value and the first illumination intensity is lower than the illumination intensity of the previous time period, calculating to obtain an average difference value according to the historical illumination intensity, subtracting the calculated average difference value from the illumination intensity of the previous time period, and taking the obtained calculation result as the corrected first illumination intensity. The method can realize the correction of the illumination intensity and improve the reliability of the parameters, and specifically, when the difference value between the first illumination intensity obtained by analysis and the illumination intensity of the previous time period is greater than a second threshold value, it is indicated that the first illumination intensity obtained by analysis has an abnormality such as inaccuracy, for example, a sudden jump of a numerical value, at this time, an average difference value is obtained by calculating the historical illumination intensity, and when the first illumination intensity is lower than the illumination intensity of the previous time period, the average difference value obtained by calculation is subtracted from the illumination intensity of the previous time period, and the obtained calculation result is used as the corrected first illumination intensity to replace the first illumination intensity obtained by analysis.
