基于单片机的升降机自动控制模型

采用单片机设计了一种新型的升降机自动控制系统。系统硬件部分采用ATMEL公司单片机AT89S52芯片为主控芯片,不仅实现了普通升降机所具有的基本功能—依据乘客在不同的楼层及上下楼的要求,自动运转或等待,而且还实现了对于超重情况有报警提示,并实现了升降机到位后语音播放、液晶显示提示乘客以及紧急情况乘客按键报警等普通升降机所不具备的功能。

Automatic Control of Building Lift Model Based on Single-chip Microcomputer

This design adopts the single chip microcomputer AT89S52 of ATMEL as the main control and the assit control chip to achieve the following targets. The elevator can be controlled to stop or wait based on the passengers request. It can warn the manager if there is the state of excess. The elevator can be controlled to play the voice and light the LCD to hint the passengers. If there is some emergence has happened, the elevator can be stopped. At the same time, the elevator can compute the number of the passengers. The system will be cut the power to guarantee the safety of the passengers and the system when the elevator run out of the top floor.
