| As a new domain in the computer application,Embedded Real-time Operation System is wideky concerned by its concision and efficiency.As to the application of the Embedded Real-time Operation System in the intelligent fumigation based on ARM,this paper applys high performance embedded microprocessor and embedded Real-time Operation SystemμC/OS-Ⅱ,applysμC/OS-Ⅱto reasonably distribute CPU time and system resource,also predigests software programming,ensures the real time of system,improves the reliability of system.This paper discusses the development,actuality and future of the fumigation control system and the embedded Real-time operation system in our country and other countries.This paper introduces the conception,characteristic and relation between embedded system and Real-time Operation System,expatiates the neeessity of applying RTOS in embedded application,indicates the control domain development trend of applying embedded Real-time Operation System to develop a safe,efficient control system.LPC2292(ARM7) of PHILIPS is used as the main control core in hardware design,Intelligent fumigation control system uses ARM7+PIC as system structure.In software It deeply discusses the logic structure,control tactic and methods of fumigation control system,realizes the collectivity structure design and task distributed of the fumigation control system,brings forward the necessity of the transplant real-time operation system to manage fumigation control system.It briefly analyzes the core structure ofμC/OS-Ⅱ,realizes the transplanting ofμC/OS-Ⅱin ARM7,then describes the means of amending the documents related to the ARM7 in transplant process and comes up with major code of transplant. As a software develop platform based onμC/OS-Ⅱ,it designs main task modules and interrupted module of fumigation control system,expatiates methods of communication between tasks or between tasks and interruptions,realizes the application of embedded Real-time Operation SystemμC/OS-Ⅱin fumigation control system. |
