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 internal counter operation, which not only eliminates the single function of the light-controlled street lamp control method, which cannot realize further The problem of energy saving also overcomes the problem that the time-controlled street lamp control method cannot cope with the temporary change of lighting conditions caused by abnormal climate and the problem of cumulative error of the real-time clock, and does not need to write the season of sunrise and sunset based on longitude and latitude change value

Embodiment 1

[0027] figure 1 It is a flowchart of an embodiment of an intelligent street lamp control method of the present invention. As shown in the figure, an intelligent street lamp control method includes:

[0028] Judging the state of the photosensitive element;

[0029] The internal counter TC counts, and the time length recorder TS records and generates the time length digital quantity TL of day or night;

[0030] Process the digital quantity TL of the duration of day or night to generate the averaged digital quantity AL;

[0031] Read in the data that can set the segmenter TD for energy-saving switch segmentation, and compare it with the internal counter value;

[0032] If the counter value is greater than the segment value, a light-on instruction is generated;

[0033] If the counter value is less than the segment value, a light-off command is generated.

Embodiment 2

[0035] 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 or an averaged digital quantity AL about the duration of the day or night for one day or several days in the time recorder TS , 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... ALn is compared with the count value of the counter TC through the numerical comparator CC, so as to obtain the switch signal of the relative comparison strategy...

Abstract

The invention discloses an intelligent streetlamp control method, including a light sensor, a duration recorder TS aiming at daytime or night in a day or several days in the past, a counter TC, a value comparator CC and a fixed frequency source OS, wherein the value comparator CC compares the size relationship between switch segmentation values TL1, TL2 ... TLn or AL1, AL2 ... ALn of the duration recorder TS and the time-base pulse value recorded by the counter TC to obtain the energy-saving control strategy of streetlamps, and thereby streetlamp switch control signals of K1, K2... Kn are obtained. According to the intelligent streetlamp control method, the switching on and switching off of the streetlamps can be effectively controlled without inputting absolute time and geographical information on the spot, and without configuring external and internal accurate clocks or calendars.

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...
