| 摘 要： | 新型教学电梯基于串行总线分布式控制设计,由上位机、运行控制、轿厢控制、内呼控制、外呼控制5种智能单元组成。采用主从式通信:上位机为主站,其余单元均为由独立单片机进行控制与通信的从站。以串行总线分布式控制取代传统的集中式控制,明显优化了系统性能,简化了布线,提高了可靠性。

| Abstract: | The new-style teaching elevator is designed based on serial bus distributed control,it has five kinds of intelligent units,upper computer,move control,car control,inside call control,outside call control.Adopts master-slave communication: upper computer is master,others are all slave which realize control and communication by independent MCU.Replaces traditional centralized control,serial bus distributed control optimizes the system control,simplifies wiring,improves reliability remarkably. |
