Design and Implementation of Elevator Group Controllor Based on LPC2210

Applying 32-bit embedded microcontroller can much enhance the performance of the elevator group control system. The elevator group control system is introduced briefly, and then the design method and the architecture of elevator group controller based on embedded system technology are discussed in detail, including the framework of the group controller,the hardware design based on LPC2210 （32-bit microcontroller,ARM7TDMI-S CPU as core）,and the design of the relative periphery modules. As for the software design, μC/OS-Ⅱ, the open sourced real-time operating system,is chosen as software platform. The migration of μC/OS-Ⅱ to LPC2210 is investigated in particular. Finally,the structure and process of the elevator group control program based on μC/OS-Ⅱ are presented.
