Research Of Auto Sterilizer Controlling System Based On Embedded System

Today, the computer technology and information technology are developed at a high speed, computer and computer technology, apply to daily life widely. The modern computer has already gone beyond the concept of the early computer, the embedded computer that is applied extensively is one kind. Embedded computer (embedded system ), having no precise definition , frequently mean the computer systems that hide on industrial system , weapon system or a electromechanical instrument , fulfilling one or more particular functions . It is a close combination of the software and hardware. It having the merit of small program codes, highly automated, being fast of response. Now, the embedded technology Based on ARM has been a light spot of the embedded field.The pulsating vacuum sterilizer is a new kind sterilized apparatus developed in the middle of the 1990s, because of adopting the pulsating vacuum technique , it is effectual to sterilize , and apply to the hospital's supply room , operating room , pharmaceutical factory and scientific research department extensively. Applying embedded technology based on ARM to sterilize control system , researching and developing one low power and cost dissipation, high-performance sterilized control system, making it reach good sterilization control effect, have important realistic significance in updating of the sterilizer's control technology.This paper introduces the domestic and international's current situation of sterilizer, research contents and significance and the key technology to sterilize control system at first, presents the technology line of designing the control system, And establishs the foundation of the following concrete software and hardware designe.And then designing the hardware of the sterilizes control system. drawing the circuit principle picture of each sub module on the basis of designing systematically in the front, PCB the board, until finishing the common hardware platform of the system. Then, designing the data collection circuit which offers data to common platform; In order to make the control system have friendly man-machine interface, the man-machine interface module has been designed.At last, after the circuit board has designed and debugged successfully , the guide procedure-BIOS is designed and modified, then the transplantation of the operating system uClinux and the development of all application software. here using the figure interface systematic MiniGUI in developing the figure interface.
