The difference between the embedded tablet PC and the 4U type industrial computer in general lies in the size. If you don't consider the brand, you must first determine the environment in which you need a small fanless embedded computer. Embedded computers basically have little room for IO expansion, and basically there is no way to insert a few IO cards. If it is a full-slot passive backplane (usually standard 4), 12 fast IO cards can be inserted. Then you have to consider the number of external connection ports (serial port, network port, usb, display, etc.). For example, if you want to connect many external instruments or other scanners and other devices, you may need multiple serial ports, and then you have to consider the type of serial port, which is ordinary 232 or 485 or 422 common in industry. Next, consider whether you need a low-power CPU, whether you need a PCI Express bus, and power supply. After that, consider the application environment. Temperature and humidity, dust tolerance, seismic and shock resistance level, waterproof level, electromagnetic interference, mean time between failures, etc.
As an industrial computer, an embedded tablet computer is the same as other commercial computers. There will also be some more common parameter terms, which we can also understand as professional terms. For example, the thickness of the industrial control computer is described as 1u, 2u, 3u, 4u, which means that the thickness of the industrial control cabinet is a few U. What is the structure of the embedded industrial computer?
Industrial Tablet PC
passive backplane
The slot of the passive backplane is composed of multiple slots of ISA and PCI bus. The number and location of ISA or PCI slots can be selected according to needs. The board has a four-layer structure, and the middle two layers are ground and power layers. This structure can reduce the mutual interference of logic signals on the board and reduce the power supply impedance. The backplane can be plugged into various boards, including CPU cards, display cards, control cards, I/O cards, etc.
CPU card
There are many types of IPC CPU cards, which can be divided into long cards and half-length cards according to the size, and can be divided into 386, 486, 586, PII, PIII motherboards according to the processor, and users can choose and match according to their needs. Its main features are: working temperature 0-60 degree ; equipped with a "watchdog" timer; low power consumption, 5V/2.5A at maximum.
Industrial power supply
is an AT switching power supply, with an average trouble-free running time of 250,000 hours.
all-steel chassis
IPC's all-steel chassis is designed according to the standard, anti-shock, anti-vibration, anti-electromagnetic interference, and can be installed inside a passive base plate compatible with PC-bus.
Other Accessories:
Other accessories of IPC are basically compatible with PCs, mainly including CPU, memory, graphics card, hard disk, floppy drive, keyboard, mouse, optical drive, monitor, etc.
