摘要
对三层老式货运电梯进行改造,要求每层楼可以直接输入楼层号,控制器能直接将货运电梯从当前楼层运行到目标楼层。综合成本和控制需求,制作一个以89C51为主控制芯片,行程开关产生检测信号,由继电器控制交流接触器控制电机正反转的控制系统。具体阐述了系统的总体设计、硬件结构和软件流程。该控制器具有运行安全可靠,制造成本低,在改造的货运电梯上使用效果良好。
Three of the factory to transform the old freight elevator, requiring direct input on each floor floor number, the controller can directly run the freight elevator to the target from the current floor floor. Comprehensive cost and control requirements, making an 89C51 chip-based control, limit switch detection signal generated by the AC contactor control relay cofitrol motor reversing control system. Specifically addressed the overall system design, hardware architecture and software process. The controller has a safe and reliable operation, low manufacturing costs, freight elevator in the transformation to use to good effect.
