Below with reference to accompanying drawings the road lamp switch based on distribution box of the present invention is controlled platform
Embodiment is described in detail.
The formal mankind attempt carrying out artificial lighting on avenue and start from the beginning of the 15th century.1417
Year, in order to allow London winter black night become clear evening, Mayor of London's Henry bar pauses issue
Order, it is desired in outdoor suspended lamp illumination.Later, his proposal had been got back French
Support.The when of 16 beginning of the century, outside Paris residential building window at the front, illumination must be installed
Light fixture.During Louis 14, the street in Paris occurs in that many street lamps.1667, it is referred to as "
Sun king " Louis 14 the most formally promulgated city illumination decree.Exactly because this portion
The promulgation of decree, the governance of Louis 14 is just referred to as France's historical " bright epoch ".
Street lamp is that the road at night brings light, and the walking for pedestrian at night provides good regarding
Open country, also gives people's security simultaneously, especially at each traffic intersection in city, and street lamp
Quantity most.Although the power consumption of single street lamp is the highest, but owing to having in the distribution of street lamp
The feature that spacing distance is short, the overall energy consumption of the street lamp in each city is the highest, if
Ensureing that Urban Residential Trip is convenient while, effectively reduce the street lamp power consumption in city, be every
The municipal administration department in one city wishes one of problem of solution.
But, street lamp of the prior art opens and closes and controls to be all unified carrying out, at the curtain of night
When coming, open all street lamps simultaneously, simultaneously close off all street lamps at day, such open
Pass mode is difficult to control overall street lamp energy consumption.The municipal administration department in some cities is by satisfying the need
Lamp is updated regenerating, and replaces existing old-fashioned street lamp for example with LED street lamp, such
Although substitute mode reduces overall energy consumption to a certain extent, the quantity yet with street lamp does not has
Being reduced, open and close mode does not change, and the overall energy consumption reduced is the most limited.
In order to overcome above-mentioned deficiency, the present invention has built a kind of road lamp switch control based on distribution box
Platform processed, it is possible to use effective street lamp open and close control mode is relative for street lamp quantity
More traffic intersection, it is achieved self adaptation street lamp open and close based on real-time pedestrian's quantity controls,
Thus while ensureing traffic intersection night illumination effect, cut down city street lamp administration section
Operation cost.

The not exclusively shortcoming of prediction.
From CPLD developing history, 20 century 70s, FPGA the earliest
Device--PLD is born.Its export structure is programmable logic macrocell, because his is hard
The design of part structure can be completed by software (to be equivalent to artificial portion of design bureau indoor knot after house is built
Structure), thus his design has a strongest motility than the digital circuit of pure hardware, but its mistake
Also them are made can only to realize the circuit that scale is less in simple structure.Can only for making up PLD
Design this defect of small scale in circuitry, 20th century the mid-80, be proposed complex programmable
Logical device--CPLD.Network, instrument and meter, automotive electronics, numerical control have been goed deep in this application
The aspect such as lathe, Space TT&C system.
CPLD have the following characteristics that there is flexible in programming, integrated level is high, design and develop the cycle
Short, scope of application width, developing instrument are advanced, design and manufacture cost is low, hardware to designer
Skill requirement is low, standardized product without the feature such as test, strong security, price be popular, can
Realize fairly large circuit design, be therefore widely used in prototype and the product of product
Produce among (typically below 10,000).Nearly all application middle and small scale general digital collection
The occasion becoming circuit all can apply CPLD device.CPLD device has become electronic product can not
The ingredient lacked, its design and application become a kind of technical ability that Electronics Engineer is indispensable.
