The Design Of The Controller In State Basing On LPC2104

Gather to spread the system DCS to occupy the important position in the industry process control.Even push now in addition to total line system FCS of new spot.Total line system of the spot is forerunner whom present stage apply of control system.But even is the new spot total line control system and also can't negotiate in same network under the share data, and support the spot controller that TCP/ IP protocol made up this shortage.This text mainly studies to carry the spot controller of the embedded system design according to the controller of LPC2104 and it connects to go into the Internet method.The spot controller adopts the LPC2104 in the series of LPC2100 of the Philips Company, carrying on the design of thehardware and software.Among them; the hardware part carries out the data conversion, the control output, the spot the function that data manifestation.The software part passes the conjunction of the RTL8019AS netcard chip realization and Internet.The spot controller is an appearance that can connect into the Internet to control the function physically.Therefore how the safety that guarantees that the spot controller is on the network is an important problem.This text described a few method of the assurance system safety.Through the verification of possibility, connect the embedded equipments into the Internet way is to slice actually viablely.This kind of method increased many vivid for the FCS design, make whole spot control system design the way of thinking is clear, and convenience the realization of the network function.
