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

A kind of intelligent streetlamp control

Technical field

The present invention relates to road lamp switch control method, particularly relate to a kind of intelligent streetlamp control not needing manual intervention automatically to identify.

Background technology

Existing controller for road lamp generally adopts light-operated or timed manner.The automatic independent switch that light-operated controller for road lamp can realize simple night in daytime controls, but further energy-conservation object cannot be realized, the a certain moment after street lamp is opened such as is needed to close, even at night, such as in the second half of the night, when Pedestrians and vehicles rareness, to realize the energy-conservation of a nearlyer step.Also again cannot open or close in predetermined duration section, time such as first rays of the morning sun closes on, illuminate road in advance, facilitate pedestrian and the vehicle of getting up early.Time controlled type method for controlling street lamps carries out switch control rule as a reference with the real-time time of locality, coordinate in addition write on-site latitude and longitude the seasonal variations value in sunrise sunset moment that converts out, just can realize the Energy Saving Control of multiple strategy.But the shortcoming of time controlled type to tackle the temporary variations of the illumination condition that abnormal weather causes, and during extra artificial school required for the real-time clock error of accumulation or when external communication device carries out synchronous school.

Summary of the invention

The present invention provides a kind of intelligent streetlamp control to solve deficiency of the prior art, impression value based on photoelectric sensor controls the capacitive equipments of internal counter operation, not only eliminate light-operated method for controlling street lamps function singleness, problem energy-conservation further cannot be realized, also overcome time controlled type method for controlling street lamps and cannot tackle the temporary variations problem of the illumination condition that abnormal weather causes and the accumulated error problem of real-time clock, also do not need the seasonal variations value of the sunrise sunset write based on longitude and latitude.

For achieving the above object, the technical solution used in the present invention is:

A kind of intelligent streetlamp control, is characterized in that, comprising:

Light-sensitive element LS experiences the illumination condition of external environment condition, draws the moment of sunset and sunrise;

Producing internal timebase pulse by fixed-frequency source OS goes the night duration of actuation counter TC to past one day or continuous a couple of days to count;

Then duration register TS be formed about too one day or the daytime of a couple of days or the duration digital quantity TL at night or average after digital quantity AL, duration register TS be can record the previous day or several days in the daytime or night duration or average a kind of digital memeory device, can be hardware memory also can be software memory, can keep and better a record data;

Then get this duration digital quantity TL or AL as a reference, carry out power down switch segmentation through sectionalizer TD can be arranged;

Then each switch-segment value TL1, the TL2 of TS is compared by digital comparator CC ... TLn or AL1, AL2 ... ALn sum counter TC record time main pulse value numerical values recited relation to obtain the Energy Saving Control strategy of street lamp, thus draw K1, K2 until the road lamp switch control signal of Kn;

Finally control opening and closedown of street lamp that night according to the Energy Saving Control strategy of street lamp by Street lamps control switch CK.

As a kind of preferred version of intelligent streetlamp control of the present invention, described arranged record duration sectionalizer TD can according to configured segmentation can arrange switch to the duration digital quantity TL of register TS or average after digital quantity AL carry out segmentation, fragmentation value TL1, TL2 ... TLn or AL1, AL2 ... ALn, fragmentation value can adopt the hardware of data segments mode or software divider that analog form voltage divider also can be adopted to obtain, and the hop count of segmentation is minimum is 1.

As a kind of preferred version of intelligent streetlamp control of the present invention, the Energy Saving Control strategy of described street lamp can arrange switch J1 ~ Jn by segmentation and set in advance, minimal amount is 1, segmentation can arrange the switch or wire jumper that switch can be hardware, also can be software can prefabricated ROM numerical value.

As a kind of preferred version of intelligent streetlamp control of the present invention, any one or a few the combination in described Street lamps control switch CK electromagnetic relay switch, electromagnetic contactor switch, magnetic latching relay switch, contactless solid switch SSR.

As a kind of preferred version of intelligent streetlamp control of the present invention, described light-sensitive element LS is any one in photodiode, triode, silicon photoelectric cell slice, the photo resistance of cadmium sulfide class.

As a kind of preferred version of intelligent streetlamp control of the present invention, described internal counter TC is the combination of any one or both in the counter of microprocessor internal under the integrated circuit counter of hardware, software pattern.

As a kind of preferred version of intelligent streetlamp control of the present invention, described fixed-frequency source OS is the combination of any one or they in resistance capacitance inductance, ceramic oscillation source, crystal oscillation source.

As a kind of preferred version of intelligent streetlamp control of the present invention, described fixed-frequency source OS is outside comparatively stable frequency source, the preferably frequency of Alternating Current Power Supply.

As a kind of preferred version of intelligent streetlamp control of the present invention, described digital comparator CC is made up of one or more digital hardware comparator.

As a kind of preferred version of intelligent streetlamp control of the present invention, described digital comparator CC is any one composition in comparison device program or analog comparator, in order to the timing values and TL1 ~ TLn or AL1 ~ ALn that compare TC each segmentation numerical value thus obtain the road lamp switch control signal of K1 ~ Kn.

Beneficial effect:

Intelligent streetlamp control of the present invention passes through the generation of a photovoltaic element perception dusk and first rays of the morning sun, each dusk and first rays of the morning sun are counted, extract these count values, relatively analyze, obtain relatively reasonable numerical value and control strategy, with this numerical value and strategy as the scheme opening street lamp the night that will arrive, do not need manual intervention, based on the switching time of local conditional, automatic identification first rays of the morning sun and dusk, do not need personnel on site to input, the switching time of street lamp can change with seasonal variations.Do not need on-the-spot input absolute time, geographical information, do not need to be equipped with outside, inner precision clock or calendar yet, Variation control strategy can be carried out according to the demand of different user, and comprise and be not limited to the control strategy of patent.
