摘要
对于传统的教学楼的门都是需要人为去打开和关闭,每天这样反复工作费时费力。为解决这一问题,本项目提出加装自动门控装置,采用超声波测距技术和时间继电器设计一种自动门锁,用两种模式对教学楼门实现自动关闭,无需人员值守,省时省力。该设计安全性高,噪声低,成本低。
In the traditional building doors are need to open and close, human work repeatedly so time-consuming to every day.To solve this problem, the project is equipped with automatic control device is put forward, using ultrasonic ranging technology and design an automatic door lock, time relay with two modes of teaching stair-door shut down automatically, without staff unattended, save time and effort.The design of high safety, low noise and low cost.
