| As a new domain in the computer application, embedded Real-time operation system is widely concerned by its concision and efficiency. As to the application of the embedded Real-time operation system in the distributed intelligent elevator Based on CAN-Bus , this paper apply high performance embedded microprocessor and embedded Real-time operation system u C/OS-II, apply uC/OS-II to optimize the task distribute CPU time and system resource ,also predigest software programming , ensure the real time of system , improve the reliability of system.This paper discuss the development .actuality and future of the elevator control system and the embedded Real-time operation system in our country and other countries.This paper introduce the conception . characteristic and relation betweep embedded system and Real-time operation system, expatiate the necessity of apply RTOS in embedded application, indicate the control domain development trend of apply embedded Real-time operation system to develop a safe .efficient control system.The main study contents of this paper as follows:In hardware design use (DSP) TMS320LF2407 as the main control core, use DSP+CPLD as system structure to develop a new. intelligent elevator control system.In software first deeply discuss the logic structure . control tactic and method of elevator control system, realized the collectivity structure design and task distributed of the elevator main control system, bring forward the necessity of the transplant real-time operation system to manage elevator control system.Briefly analyze the core structure of uC/OS-II, realized the transplant of u C/OS-II in (DSP) TMS320LF2407. Then describe themethod of transplant in TMS320LF2407 in detail.Apply uC/OS-II as software develop platform, designed main task modules and interrupt module, expatiate methods of communication between tasks, realized the practiced application of embedded Real-time operation system uC/OS-II in elevator control system.
