基于人员出入的激光检索系统设计

激光由于具有方向性好,亮度高,单色性好等特点而被广泛应用,基于激光的特点,设计了一个基于人员出入的激光检索系统。本系统采用Arduino uno开发板来控制激光发射与接收,通过屏幕操作启动中央处理器进行数据处理,在集成开发板的控制下,对出入的人员进行计数,在LED屏幕上显示当前到达的总人数,通过实验测试,本系统实现无接触检测某些场所内的人流量。

A Design of Remote-Controlled Chalkboard Eraser

Chalkboard erasers that are commonly used in many schools and education organizations have the poor ability in removing the dust off the chalkboard and collect them. The dust that is not collected will be taken into human bodies via inhalation, which will lead to respiratory diseases. Therefore, it is crucial to design a chalkboard eraser that can collect the dust effectively. If the eraser can be controlled both remotely and manually by people, it can further reduce the amount of dust taken in by human bodies. To achieve remote control, a micro-controller is needed to transfer the infrared radiation (IR) into signals that can control electric motors to move around on the chalkboard. Furthermore, the microfiber is also used as the cleaning material to improve the performance of dust cleaning and collecting. A vacuum pump is needed to create negative pressure between the eraser and the chalkboard so that the eraser can stick to it. The result shows a stronger ability in removing and collecting dust. With the help of the Arduino UNO board, the remote control is successfully achieved, and the eraser can move on the chalkboard freely according to the order.

智能油烟检测系统的设计

本设计用于检测抽油烟机内部储油槽中的油渍量和油烟机内壁上的油渍层的厚度,装置传感器安放在油烟机内部的储油槽和安放在内壁上。油渍超过智能油烟检测器的报警监测量,检测器就会发出警报,提醒人们倒掉储油槽中的油渍并清理储油槽和油烟机内壁。
