Problems solved by technology

[0003] In order to solve the deficiencies in the prior art, the present invention provides an intelligent street lamp control method, based on the sensory value of the photoelectric sensor to control the relative comparison method of the counter operation, which not only eliminates the single function of the light-controlled street lamp control method, which cannot realize further energy saving It also overcomes the problem that the time-controlled street lamp control method cannot cope with the temporary changes in lighting conditions caused by abnormal weather and the cumulative error of the real-time clock, and does not need to write the seasonal changes of sunrise and sunset based on longitude and latitude value

Embodiment 1

[0026] figure 1 It is a flowchart of an embodiment of an intelligent street lamp control method of the present invention, including:

[0027] Judging the state of the photosensitive element;

[0028] The counter TC counts, and the time length recorder TS records and generates the time length digital quantity TL of day or night;

[0029] Process the digital quantity TL of the duration of day or night to generate the averaged digital quantity AL;

[0030] Read in the data that can set the segmenter TD for energy-saving switch segmentation, and compare it with the counter value;

[0031] If the counter value is greater than the segment value, a light-on instruction is generated;

[0032] If the counter value is less than the segment value, a light-off command is generated.

Embodiment 2

[0034] An intelligent street lamp control method, such as figure 2 As shown, it contains a photosensitive element, a time recorder TS for the day or night in the past day or several days, a counter TC, a numerical comparator CC, and a fixed frequency source OS, which is determined by the fixed frequency source OS Generate an internal time base pulse to drive the counter TC to count the night duration of the past day or several days, and then form a digital quantity TL about the length of one day or a digital quantity after the day or night average of the past few days in the time length recorder TS AL, and then take this time-length digital quantity TL or AL as a reference, and carry out energy-saving switch segmentation through the settable segmenter TD, by setting different switch time segments TL1, TL2...TLn or AL1, AL2... of TL or AL ...ALn, and the count value of the counter TC are compared by the numerical comparator CC, so as to obtain the switch signal of the relative...

Abstract

The invention discloses an intelligent street lamp control method, comprising a photosensitive element, a duration recorder TS for day or night in the past day or several days, a counter TC, a numerical comparator CC, and a fixed frequency source OS, The energy-saving control strategy of the street lamp is obtained by comparing the value of each switch segment value TL1, TL2...TLn or AL1, AL2...ALn and the time base pulse value recorded by the counter TC by the numerical comparator CC. The street light switch control signals from K1, K2 to Kn are obtained. By adopting the present invention, the switch for controlling the street lamp can be effectively implemented, and there is no need to input absolute time and geographic information on the spot, nor to be equipped with an external or internal precise clock or calendar.

Description

technical field [0001] The invention relates to a street lamp switch control method, in particular to an intelligent street lamp control method for automatic identification without manual intervention. Background technique [0002] Existing street lamp controllers generally adopt light control or time control. The light-controlled street lamp controller can realize simple automatic and independent switch control of day and night, but it cannot achieve further energy-saving purposes. For example, it needs to be turned off at a certain time after the street lamp is turned on. When vehicles are scarce, to achieve further energy saving. It also cannot be turned on or off again for a predetermined period of time. For example, when the dawn is approaching, the road is illuminated in advance to facilitate early pedestrians and vehicles. The time-controlled street lamp control method uses the local real-time time as a reference for on-off control. In addition, it can realize multi...
