Detailed description of the invention
Below with reference to accompanying drawings to the taxi information promulgating platform based on distribution box of the present inventionEmbodiment is elaborated.
Conventional distribution box has two kinds of wooden and metal systems, because metal distribution box degree of protection is wantedHigher, so or the use of metal many.
Distribution box can be classified as follows by architectural feature and purposes:
(1) the board-like distribution box of stationary plane, often claims switchboard or switchboard. He is that one has faceThe open-type distribution box that plate blocks, there is protective action in front, and the back side and side still can be touched chargedPart, degree of protection is low, can only be used for power supply continuity and the lower industrial and mineral of reliability requirementEnterprise, is used as transformer room's centrally connected power supply.
(2) protection (closed) distribution box, refers to except installed surface other all sidesA kind of low-tension distribution box that face is all closed. Switch, protection and the monitoring control of this chestThe electrical equipments such as system, are installed in a closure made from steel or insulating materials, canLean on wall or install from wall. In cabinet, between every loop, can not add quarantine measures, also can adoptMetallic plate or the insulation board of ground connection are isolated. Conventionally door has mechanical interlocking with main switch operation.Go back in addition protected type bench-type distribution box (being console), on panel, be equipped with control, measurement,The electrical equipment such as signal. Protection distribution box is mainly used as the power distribution equipment at technique scene.
(3) drawer-type distribution box. This class distribution box adopts steel plate to make closure, turnoverThe electric elements of line loop are all arranged in the drawer that can extract out, and formation can complete a certain class power supplyThe functional unit of task. Between functional unit and bus or cable, with the metallic plate of ground connection or mouldThe feature board that material is made separates, and forms bus, functional unit and three regions of cable. Each meritCan between unit, also there be quarantine measures. Drawer-type distribution box have higher reliability, security andInterchangeability, is more advanced distribution box, and distribution box majority refers to drawer-type distribution box. TheyBe applicable to the industrial and mining enterprises, the skyscraper that require power supply reliability higher, as central controlledDistribution center.
(4) power, light distribution distribution box. Mostly be closed at right angle setting. Because making useClose difference, shell protection grade is also different. They are joined mainly as industrial and mining enterprises production sceneElectric installation.

Alternatively, in described distribution platform: adopt the internal memory of AVR32 chip to replaceChange FLASH memory; Wavelet transformation device and morphological image treatment facility adopt respectively notThe fpga chip of same model is realized; Pedestrian's quantity is more, and the passenger flow of traffic intersection address refers toNumber is larger; And external door can adopt double-fold structure, for increasing the intensity on external door four limits and increaseStrong water-proof function.
In addition, FPGA (Field-ProgrammableGateArray), i.e. field-programmableGate array, he further sends out on the basis of the programming devices such as PAL, GAL, CPLDThe product of exhibition. He is as a kind of semi-custom electricity in special IC (ASIC) fieldRoad occurs, has both solved the deficiency of custom circuit, has overcome again original programming device doorThe shortcoming that circuit number is limited. Completed with hardware description language (Verilog or VHDL)Circuit design, can, through simple comprehensive and layout, be burned onto FPGA enterprising fastRow test is the technology main flow of modern IC design verification. These can be edited element and can be usedRealize some basic logic gates (such as AND, OR, XOR, NOT) orMore more complex combination function is such as decoder or mathematical equation. At most FPGAThe inside, also comprises for example trigger of memory cell (Flip-flop) in these editable elementsOr the block of memory that other are more complete. System designer can be as required by editableConnecting the logical block of FPGA inside is coupled together, just looks like that a breadboard is placed inIn a chip. The logical block of a finished product FPGA after dispatching from the factory is be connected can be according to establishingMeter person and changing, so FPGA can complete needed logic function.
FPGA is in general slow than the speed of ASIC (special IC), realizes sameIt is large that the function ratio ASIC circuit area of sample is wanted. But they also have a lot of advantages such as passableFast finished product, can be modified mistake in correction program and more cheap cost. Manufacturer alsoThe cheap still poor FPGA of edit capability may be provided. Because it is poor that these chips haveCan edit capability, so the exploitation of these designs is to complete on common FPGA, soAfter design is transferred on a chip that is similar to ASIC. Another method is to useCPLD (ComplexProgrammableLogicDevice, CPLD).The exploitation of FPGA has a great difference with respect to the exploitation of conventional P C, single-chip microcomputer. FPGA is with alsoRow operation is main, realizes with hardware description language; Than PC or single-chip microcomputer (be no matterVon Neumann structure or Harvard structure) operation in tandem have very large difference.
As far back as 1980 mid-nineties 90s, FPGA takes root in PLD equipment. CPLD andFPGA has comprised the Programmadle logic unit of some relatively large number amounts. CPLD gate closeDegree between several thousand to several ten thousand logical blocks, and FPGA normally several ten thousand arrive millions of.The main distinction of CPLD and FPGA is their system architecture. CPLD is an a little limitThe structure of property processed. This structure is listed as by the logical groups of one or more editable result sumRegister composition with the locking of some relatively small amounts. Such result is to lack editor's flexibility,But but there are time delay and the advantage of logical block to linkage unit height ratio that can estimate.And FPGA has a lot of linkage units, although allow like this him edit more flexibly,But structure is complicated many.
