The PXI platform application in electronic manufacturing industry

The people requirement to product technology promotes 21 centuries, and of product lifecycle short shrink to let electronic manufacturer must think to whether have platform of another kind of test with the pressure of the price, can compare traditional PC, GPIB or VXI have competition ability more for fiducial test platform. The article creates simple introduction electron the demand that checks platform, and from one, 2 case that use in electronic manufacturing industry will discuss new PXI platform how to be satisfied sensitive to the price the application that has mass-produced demand again, make a reader OK understand PXI to check the character of platform and virtue as production more. When the demand that produces test platform should have the production with need new erect to check platform, should think to test the requirement of platform to production afresh from certain and specific element, these specific element include the following. 1.

Systematic area is many electronic manufacturer or acting factory most what often trouble is how to reach inside limited space taller produce can, that is to say a same ground, how can you produce a more products? Major of course factory space majority is be held by manufacturing facilities place, but cannot dare not or would not speak up, sundry test equipment also can be the element of Lv of one final examination on the space.

Considering contractible production space normally, check systematic area especially when this element, test engineer can take module form more or be based on the system that inserts card, for example PC, VXI or PXI platform.

Next watches provide a reader the comparison of a VXI and density of PXI platform function. Box height is worn to be able to use density of patulous chamfer function on the system (patulous chamfer number is divided with box height) VXI, c dimension 9U 12 1.

3PXI, 19 1 of ～ of 6U 9U 13.

4 ～ 2.

1PXI, 17 1 of ～ of 3U 5U 6.

2 ～ 3.

Configuration of system of PXI of 　 of 2 　 offers taller function density to compare, because this can provide more close-grained test system.

But the system that is like the person that use needs a lot of adscititious GPIB instrument facility, that PXI is shown not easily in the advantage of space and price come.

But will compare with the system of traditional PC/PCI-based or VXI system, PXI platform still offers test engineer to have the choice of flexibility more. 2.

Test module to module kind the production of the product checks, checking module can be the factor that another unified exam when choosing platform measures.

Have: to testing the requirement of module commonly? Does そ of oily two of Ao of Jie of Gou of stay of proceedings of health act  mail た fan palm Yong peptide? Does oil of Chinese torreya wash return つ of mu of Piao   ? Is charm of dainty of argon of a short wooden stake low say to teach carapace of ∧ of bath of Xiao of  of  Lai angry bowstring of bully banter Xin aing concubine of an emperor  of have diarrhoea of ┯ of very hot Mao of  of ┏ of Yan Xing suddenly? it is 3UPXI dimension more.

It is however when integrated receiver interface and PXI platform the biggest challenge is the I/O that depends on concatenate instrument and test system.

For example is right at present a few high density spend test application, the connect of SCSI condition is most often be used, it is not difficult to should make the cabled yarn component that can match, but if want to put the interface of receiver on PXI system,can need more reliable reach bouncier framework, difficulty also rises relatively.

As a whole, of I/O thinking is now no matter or the receiver with specific to the choice future or treat providing will be a main index. 3.

Controller of systematic controller system has outside receive type and embedded option.

The systematic controller of type is received outside checking a system for the most part to use, be like on the desk model the computer.

The benefit that type system controller receives outside using is as follows: · does not hold VXI or number of chamfer of PXI lead plane, can offer more circumjacent chamfer to give an instrument equipment or switch implement use. · simplifies to go up with the desk of online management · of computer peripheral equipment model the computer has function of system of competitive advantage · to upgrade easily relatively on the price when box of PXI of type controller join is being received outside using, the high speed that how maintains PCI bus line transmits speed, what must have software vitrification at the same time is characteristic, is the bridge that goes up as another PCI bus line received implement? Of PCI bus line outspread cover a role with be being acted very important right now.

Restrict somewhat in the space however when or collect in data / on the special application of flow control, use embedded or veneer computer is met in the system of module type is better choice. 4.

Instrument and signal switch implement without doubt, the selection of the function that traditional instrument can provide and supplier is most wide, but the transmission rate that gets bus line of GPIB of be confined to, because this is right,the tests a function requirement of the instrument compares test rapidity to come more normally.

Generally speaking, production chamber of commerce chooses VXI or this kind of platform regards PXI as functional test system, because they are had,be likely modular, conformity of high density instrument and high speed data transmit the character of speed.

And besides the instrument judge make allowance for to consider, signal switch implement can be the point that another system architect should consider, the signal switch with the systematic quite considerable need of the person that should use especially implement even or the person that use needs another box to handle signal switch, the platform norms that how chooses to suit will affect the systematic dimension of the person that use and price.

PXI platform is opposite in the application of electronic manufacturing industry for a lot of test branches how the framework can accord with existing functional requirement to have the test system with expanding future again is most test engineer place care and have fun at.

Generally speaking, the framework that the electron makes test system can use next graphs to distinguish a few parts.

The first part is hardware framework, include systematic platform (3U or 6U) , systematic controller (outside receive form - on the desk model the computer, need tie-in PCI/PXI outspread set in order to join PXI system box or embedded PXI controller) , test instrument (independent type instrument or PXI module type) reach switch implement.

The 2nd part is software driver, hardware needs to offer the driver such as supportable LabView/VB/VC/DAQBench/PnP.

The test that the 3rd part surveys content to be recieved repeatedly is treated. It is with sufferring the blue tooth module of controversy quite in last few years exemple, from functional face character, blue tooth module is right of individual communication or peripheral equipment connecting is quite convenient and of conduce beneficial, but because its check cost to reside,do not fall high, make its price cannot fall to think to consumer from beginning to end reasonable range, cannot popularize a lot of consumptive sex commodity in great quantities so.

But the generation that checks means and platform as what provide sexual price to compare more, of the manufacturing test cost of blue tooth module reduce, blue tooth module will have new development opportunity.

A blue tooth module that is a foundation with PXI platform tests a system, computer of an industry level includes normally on its framework embedded GPIB is comfortable the instrument facility that outside matching card to use control, receives, interface of a PCI is outspread the signal of outspread PCI bus line goes to card in order to PXI platform, PCI port is contained inside PXI box outspread module, module uses the RF switch that reachs 2 to do signal switch and A/D, d/A module is used do data to collect, cooperate the composition of many segregation box place that contain module.

And the costlier in whole test system RF that outside should be being belonged to, receives checks an instrument, but the utilization rate that the instrument receives outside applying this kind of framework to be able to increase, and achieve the goal that reduces cost. Platform of conclusion 　 PXI combined the PCI bus line of open and tall efficiency because of its, the structural performance with robust CompactPCI and high density spend integrated advantage, make test system to mass-produced electron and character, PXI platform is a new option undoubtedly.
