Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1, a street lamp control method includes the following steps:
and step S1, acquiring the illuminance value Lux of the external environment of the street lamp by using the illuminometer, and correspondingly adjusting the acquisition frequency of the illuminometer according to the acquired illuminance value Lux.
And step S2, correspondingly controlling the on and off of the street lamp according to the collected illumination value Lux.
Specifically, in order to ensure the accuracy of the data collected by the illuminometer, a reasonable illuminometer needs to be selected first, and in this specific embodiment, the range of the selected illuminometer is as follows: 0.01Lx to 83000Lx, but not limited thereto, in other embodiments, the selection can be made according to practical situations, which can be easily realized by those skilled in the art and will not be described in detail.
In the collecting process, if the collected illuminance data is not in the range of 0.01Lx to 83000Lx, the collected illuminance data is judged to be invalid data and is discarded, so that the accuracy of the collected illuminance data is improved.
Then, an illuminometer is used to collect the illuminance value for 10 times, and the minimum illuminance value Lux is removedMINAnd maximum illuminance value LuxMAXAnd calculating the average value of the remaining 8 illuminance values as the illuminance value Lux acquired this time, wherein the acquisition frequency is in the nanosecond level, and more specifically, referring to fig. 2, it is not described in detail, where LuxA1 is the latest acquired illuminance value, and LuxA2 is the last acquired illuminance value, so as to further filter the abrupt change illuminance value, and ensure the value validity. Of course, in other embodiments, the number of the illuminance values for averaging may be more than 10 or less than 10, and may be specifically selected according to actual needs.
Of course, in other embodiments, other filtering methods may be used to filter the data of the illumination values.

But not limited thereto.
In this embodiment, the illuminometer includes a first illuminometer and a second illuminometer, and the first illuminometer is arranged above the lamp holder of the street lamp. The street lamps on the road are basically evenly distributed according to the distance of 35-40 meters, the illuminometers are arranged on the lamps, the positions are not easily shielded and are not influenced by the on-state of the lamps, and the illumination LP curve of natural light is really reflected, as shown in figure 4.
The second illuminometer is arranged in the middle of the road, and the condition of the road surface illuminance LD is fed back more truly, as shown in FIG. 4. In order to reduce the error of a single illuminometer and the error caused by possible shielding, in this embodiment, at least more than 3 second illuminometers are adopted on the road, and a method of synchronizing clocks is adopted among the second illuminometers to automatically collect and actively report. And averaging the illuminance values acquired by more than 3 second illuminometers to obtain the road pavement illuminance LD.
Finally, the street lamp is correspondingly controlled to be turned on and off according to the LP and the LD, specifically, in the embodiment, the street lamp is turned on when the LP < ═ 30Lx and the LD < ═ 30 Lx; when LP > -, 20ux and LD >30Lx turn off the lamp; thereby better ensuring the road lighting quality, realizing reasonable illumination, satisfying the trip safety, and greatly reducing the energy consumption. But is not limited thereto.
The LD can also be used as a parameter for dimming, so that reasonable illumination is further realized, and energy consumption is reduced.
The invention also provides a street lamp control system, as shown in fig. 5, comprising an illuminometer, a road monitoring system and a single lamp controller, wherein the road monitoring system is linked with the illuminometer and the single lamp controller, and the street lamp control method is adopted to control the on and off of the street lamp.
