The slots of the passive backplane are composed of bus expansion slots. The bus expansion slot can be composed of multiple slots to expand the Industry Standard Architecture, PCI bus, PCI-E bus and PCIMG bus according to the user’s actual application. The number and location of expansion slots can be selected according to the needs, but there are requirements for the combination of various buses according to different PCIMG bus specification versions
For example, the bus of PCIMG1.3 version does not provide Industry Standard Architecture support. The board has a four layer structure, and the middle two layers are respectively the stratum and power layer, This structural approach can reduce the mutual interference of logic signals on the board and reduce the power impedance. The backplane can be plugged into various boards, including CPU cards, display cards, control cards, I/O cards, etc.
Industrial power supply
In the early days,industrial control computers,mainly based on Intel Pentium processors,mainly used AT switching power supply,and like PCs,mainly used ATX power supply,with an average fault free running time of 250000 hours.
CPU card
There are various types of CPU cards for IPC,which can be divided into long cards and half long cards according to their size.Most of them use desktop system processors,such as the early 386486586PIII,and now the mainstream is P4,Core dual core processors,etc.Motherboard users can choose to match according to their own needs.Its main characteristics are:working temperature 0-60℃;Equipped with hardware”watchdog”timer;Some CPU cards that require low power consumption should also use embedded series CPUs.
Other accessories
The other accessories of IPC are basically compatible with PC machines,mainly including CPU,memory,graphics card,hard drive,floppy drive,keyboard,mouse,optical drive,monitor,etc.The standard length of the industrial control cabinet is 19 inches and the height is 4U.
Applicable fields
IPC has been widely applied in all aspects of industry and people’s lives.For example:control site,road and bridge control toll collection system,medical instruments,environmental protection monitoring,communication guarantee,intelligent traffic control system,building monitoring and security,voice call center,queuing machine,
POS counter cash register, CNC machine tools, fuel dispenser, financial information processing, petrochemical data acquisition and processing, geophysical exploration, field portable operation, environmental protection, military industry, power, railway, expressway, aerospace, subway, intelligent buildings Outdoor advertising and so on.
