1, PC technology to promote the development of embedded computer technology
Embedded computer is embedded in the industrial system itself, in the industrial environment can be extremely stable and reliable long-term continuous industrial-type computers. With Intel CPU and Microsoft DOS / WINDOWS architecture evolved into a de facto standard,ratchet tie dowm ISA / PCI bus Rugged Industrial PC (IPC) began to penetrate the industry. IPC despite the industrial transformation (such as the abolition of a large board, passive backplane, plug-in templates, industrial power, steel sealed chassis cooling slightly positive pressure, temperature, automatic detection and adjustment, etc.), but its essence remains not industrial-type PC, can not fundamentally solve the major motherboard horizontal, anti-vibration shock poor, non-uniform heat dissipation, component failure rate,booster cables mean time to repair (MTTR) long, difficult issues such as maintenance, it is difficult to meet the industrial control tasks demanding. In order to meet the market demand for industrial-based computers, VME bus in addition to IPC, but produced a series of PC-based, and ISA / PCI bus standard compatible embedded computer, which is more representative of the CompactPCI / PXI bus, AT96 busbattery clip , STD bus, STD32 bus, PC/104 and PC/104-Plus bus embedded industrial control machines.
