Chip realizes；Change of scale strengthens equipment, medium filtering equipment, smoothing processing equipment and gray processing
Processing equipment is integrated on one piece of surface-mounted integrated circuit；And described power distribution cabinet can also include terminals
Son row, is arranged in cabinet, is used for connecting External input terminals.
It addition, FPGA (Field-Programmable Gate Array), i.e. field-programmable gate array
Row, he is the product of development further on the basis of the programming devices such as PAL, GAL, CPLD.
He is to occur as a kind of semi-custom circuit in special IC (ASIC) field, both solves
Determine the deficiency of custom circuit, overcome again the shortcoming that original programming device gate circuit number is limited.
The circuit design completed with hardware description language (Verilog or VHDL), can be through letter
Single comprehensive and layout, is quickly burned onto on FPGA and tests, and is modern IC designs checking
Technology main flow.These can be edited element and can be used to realize some basic logic gates (ratio
Such as AND, OR, XOR, NOT) or more more complicated combination function such as decoder or number
Learn equation.Inside most FPGA, in these editable elements, also comprise memory cell
Such as trigger (Flip-flop) or other more complete block of memory.System designer can root
By editable connection, the logical block within FPGA is coupled together according to needing, just look like an electricity
Road bread board has been placed in a chip.One dispatch from the factory after the logical block of finished product FPGA and connection
Can change according to designer, so FPGA can complete required logic function.
FPGA in general speed than ASIC (special IC) is slow, it is achieved same merit
Can be bigger than ASIC circuit area.But they also have a lot of advantages such as can quick finished product,
The mistake in correction program and less expensive cost can be modified to.Manufacturer is likely to provide cheap
But edit capability difference FPGA.Because these chips have poor can edit capability, so
The exploitation of these designs is to complete on common FPGA, then design is transferred to one and is similar to
On the chip of ASIC.Another method is with CPLD (Complex Programmable Logic
Device, CPLD).
The exploitation of FPGA is very different relative to tradition PC, the exploitation of single-chip microcomputer.FPGA is with also
Row operation is main, realizes with hardware description language；Compared to PC or single-chip microcomputer (either Feng Nuo
According to graceful structure or Harvard structure) order operation have the biggest difference.
As far back as 1980 mid-nineties 90s, FPGA takes root in PLD equipment.CPLD and FPGA
Include the Programmadle logic unit of some relatively large amount.The density of CPLD gate arrives thousand of
Between several ten thousand logical blocks, and FPGA is typically several ten thousand to millions of.CPLD and FPGA
The main distinction be their system structure.CPLD is a somewhat restrictive structure.This knot
Structure is arranged by the logical groups of one or more editable result sum and the locking of some relatively small amounts
Depositor composition.Such result be a lack of edit motility, but but have it is anticipated that delay
Time and the logical block advantage to connecting unit height ratio.And FPGA is to have a lot of connection lists
Unit, although so allowing him edit more flexibly, but structure is complicated many.
Use the lightning protection power distribution cabinet of the present invention, open for LED street lamp near prior art traffic intersection
The technical problem of density domination difficulty, by transforming the power distribution cabinet of existing traffic intersection, as
Data acquisition and data communication control platform, provide intelligentized for the LED street lamp near traffic intersection
Self adaptation open and close services, thus effectively utilizes existing LED street lamp resource, reduces city LED
The operation cost of administration section.
Although it is understood that the present invention discloses as above with preferred embodiment, but above-mentioned enforcement
Example is not limited to the present invention.For any those of ordinary skill in the art, without departing from
Under technical solution of the present invention ambit, all may utilize the technology contents of the disclosure above to the technology of the present invention
Scheme makes many possible variations and modification, or is revised as the Equivalent embodiments of equivalent variations.Therefore,
Every content without departing from technical solution of the present invention, the technical spirit of the foundation present invention is to above example
Any simple modification, equivalent variations and the modification done, all still falls within technical solution of the present invention protection
In the range of.
