Compact PCI brief introduction

1 rigid standard) · HD (high density) 2mm makes foot and electrical outlet connector (IEC is approbated, bellcore) PCI of · PCI local bus line namely the meaning of peripheral equipment interconnection, released by Intel 1992, make standard of commercial PC bus line very quickly. PCI is a kind of independence the data bus line at processor, not only good and function is low-cost. Carelessness of PCI local bus line width of two kinds of data: 32 mix 64, bus line speed can amount to 66MHZ, ability of academic data processing: 32 are 264MB/S, 64 are 528MB/S. Most computer and operating system support PCI. Because have the product that supports PCI in great quantities, make PCI product already petty gain is bought easily again. Have these advantages, PCI bus line suits to be in very much high speed is calculated and apply in domain of news report of high speed data. · Ou Shi inserts calorie of rigid structure Ou Shi inserts calorie of rigid structure is by VMEbus the industrial level of promotion packs a standard one kind. Two kinds of Ou Shi insert calipers case: 3U and 6U. 3U Compact PCI blocks dimension to be 160mmx100mm, 6U card is 160mmx233.

35mm.

. Before Compact PCI gets stuck board accord with IEEE 1101.

1 with IEEE 1101.

10 standards, and can include optional EMC sealing ring disturb in order to reduce electromagnetism. The face plate before typical situation falls contains I/O port, LED indicator light and switch. Compact PCI also supports IEEE 1101.

At the back of 11 board I/O. What safeguard easily as a result of its is characteristic, face plate I/O is after on telegraphic equipment those who use is very general. Because all connecting,the line joins in hind turn receive board on, the Compact PCI in front inserts card to do not have any connecting line, because this is changing,the line need not be connected afresh when board card. Compact PCI of · pinhole connector is used accord with high density of IEC-1076 international standard to spend connector of air hermetic pinhole, the metal of its 2mm is sutural have low inductance and impedance, reduced the signal reflex that bus line of high speed PCI causes thereby, make Compact PCI system can reach 8 trough in only total line segment, compact PCI defined 5 kinds of interface: J1 arrives J5. Board card of 3U Compact PCI has J1 and J2 only two interface, 6U board J1 includes to J5. J1 and J2 are mixed in 3U the definition on board card of 6U Compact PCI is same, because this 3U is mixed,board card is in 6U Compact PCI electric going up is OK of crossing-over. 4 Compact PCI and · of contrast of photograph of traditional industry PC are durable the gender changes from system of traditional industry PC a board card often comparatives time-consuming; The user needs to loosen and move go box top. Because there may be cable of a few in-house joins between board card and peripheral equipment. And when exchanging card, must disconnect these even the line, because this this one process is very easy,make mistake. Be in so durable respect, system of traditional industry PC cannot accomplish an elephant Compact PCI system is so compact and efficient. On the other hand, compact PCI design is OK face plate unplugged flashboard gets stuck once upon a time. Change Compact PCI board card is very simple, need not tear open next box to build. In addition, because I/O wiring is the face plate after passing, the Compact PCI in front does not have any connecting on board card line, because this changes board card is very quick and handy. Maintenance time will from hour class (traditional industry PC) cut it is minute of class, shortened thereby MTTR (mean time to maintenance) . PC of industry of convention of · aseismatic sex cannot is opposite board card supplies the peripheral equipment in the system reliable and safe support, insert can secure only with among them board card at a bit. The top of card and bottom also do not have slideway support, the contact in because the joint of card and this chamfer is in easily also,shaking is undesirable. Card firmly ground secures Compact PCI to go up in box, top and bottom all have slideway support. Before face plate fixing device will before face plate and the frame all round are secured together surely. The join part of card and chamfer joins cheek by jowl through pinhole connector. All secure its firmly ground as a result of all sides of card in its locally, although be mixed in severe impact,shake a circumstance accordingly, also can assure abiding join and won't contact undesirable. The air inside the industrial PC box of tradition of · ventilated sex flows not free, cannot come loose effectively hot. Because air flow is passive bracket of negative, board card and block of disk drive place. Cold air cannot flow circularly between all board card, hot air also cannot instantly outside eduction box. Electronic equipment and circuit board meeting damages because of these cooling problems, make be out of shape, break line and life short etc. Compact PCI system is all the system is medium giving out heat board card was offerred come loose smoothly hot method. Cold air can be at will between board card flow, take away quantity of heat. Compositive in board card the system also quickened bottom fan to come loose hot process. Come loose as a result of what good mechanical design brings unobstructed hot way, compact PCI system seldom appears medicinal powder the problem of hot field. CNC Milling
