一种基于CAN总线的电梯主控系统

摘要

为了升级现有电梯控制系统,给出了一种以LPC2294为主控芯片的电梯主控系统的设计.软件上以抢占式多任务实时操作系统μ C/OS为平台,实现了电梯主控系统中的输入采集、调度分配、CAN通信、菜单输出等任务;硬件建立在LPC2294基础上,实现了与变频器互联互通、编码器脉冲反馈的采集、井道开关量的输入输出等.%In order to upgrade the existing elevator control system, this paper presents a design of the main Controller in the elevator control system based on Micro Controller Unit of LPC2294. As for the Software design, the preemptive multitasking real-time operating system μ C / OS is chosen as platform of the elevator system implementing the input/output, scheduling distribution, CAN communication; The hardware design with LPC2294 to achieve interoperability with the inverter, collection for pulse encoder feedback, input and output, etc.
