Description

A kind of multi-period street lamp control device

Technical field

The present invention relates to a kind of street lamp control device, relate in particular to a kind of multi-period intelligent road-lamp control device.

Background technology

City street lamp is being brought into play more and more important effect as the main illuminations in each city in daily life.The street lamp in some city, it is bright and colourful under the setting off of the night sky, more to seem, coloured and dazzling, has become a requisite peculiar view in city.And China's city street lamp control at present generally is light-operated, Artificial Control or clock, and this brings the very big wasting of resources for China, also brings very big inconvenience for the local resident.

Along with the development of urban municipal construction, traditional street lamp control can not adapt to the urban modernization speed of development far away with maintenance service.The urban municipal construction makes rapid progress, broad street, and various street lamps have brought the glamour at night that has also increased the city bright the time to the city.But because road, street lamp is numerous, and with quick, modern urban construction is incompatible for the conventional artificial management mode.Even if being modern singlechip technology, the city street lamp control system applies to product effective and inevitable in the urban municipal construction. under situation about bothering about completely without the people, system is also with rigorous orderly work.Under the spring tide of various management automation, add the extensive urban construction in each city of China, street lamp control system must have the vast market space! According to measuring and calculating, the street quantity in a city realizes management and system maintenance greater than 100 with regard to necessary being matched with it by a cover information management system, and the city-level city of Chinese certain scale is very how, and therefore domestic demand meeting certainly is very vigorous!

With light-operated, then when sunlight such as rainy weather were insufficient, control device also can move as only, and street lamp is lighted; As not only having wasted human resources with Artificial Control but also controlled by people's subjective thought, there is not certainty; Like simple clock, then control device is only controlled the light on and off of street lamp every day by regular time; And for a certain specific city, the rise of sun every day and the time that falls are different, and street lamp also can light when sunlight is good, and these have all caused waste of power resources.In addition, avenue before midnight pedestrian is many, and the pedestrian is few after midnight, in the second half of the night can be suitable turn off some street lamps, so just practiced thrift electric energy.Obviously, some functions are difficult to meet the demands with light-operated or clock merely like this.A kind of new method for controlling street lamps has been proposed for this reason: the visual characteristic of light and shade perception is controlled the open and close of street lamp according to solar activity rule table and human eye.Solar activity rule table is by the formal information of observatory's issue, has authority, has also strengthened the accuracy of control device.The present resource of China is very nervous, and especially the situation that supply falls short of demand has appearred in the electric power resource of North China especially, and this more requires our energy savings, so the method will be made huge contribution for the energy-conservation cause of China.

Solar activity rule table is the sunrise sunset timetable in 1 year in a certain ground by observatory's issue; According to this rule table, add accurate clock circuit, can extract sunrise sunset any a day in the middle of a year constantly; If longitude and latitude changes; Can calculate 1 year local sunrise sunset timetable, be equipped with the powerful processing capacity of microprocessor, can realize throughout the year the most nearly 99 sections accuracy controlling street lamp; The adding of human-eye visual characteristic function has more improved the performance of control device, also makes street lamp control have more hommization according to human eye to light and shade perceptibility characteristic.

Summary of the invention

The present invention adopts the core of monolithic micromonitor system as the street lamp control device; With the split-second precision integrated chip is timing unit; With low-power consumption dot character LCD MODULE is display unit; With contactless controllable silicon is control unit, and adopts the zero cross fired technology to reduce the pollution to electrical network.

Multi-period intelligent road-lamp control device has following function:

Realize Based Intelligent Control according to different longitude and latitude sunrise sunset rule and human eye light and shade perceptibility to street lamp.

Set control mode one of (both or all) and period control content according to user's needs.

Have automatic protection functions such as overcurrent, overvoltage.

Additional function is set.Like functions such as emergent, calendars.

Below, be described with reference to the accompanying drawings preferred embodiment promptly to above-mentioned purpose.

Description of drawings

Shown in Figure 1 is according to the in-built block diagram of the control device of preferred embodiment of the present invention.

Shown in Figure 2 is according to the in-built block diagram of the control device of second embodiment of the invention.
