基于“互联网+”的超声波距离检测创新设计

Innovative design of ultrasonic wave distance detection scheme based on "Internet+"

距离检测方案的设计是在超声波传感器基础上,实现自行检测、自动判断、短信自动通知等功能。通过超声波进行距离检测并给出信号,由单片机对采集信号进行整理,针对采集结果对手机模块工作状态进行调整,若采集信号小于标准信号,手机模块工作;若大于标准信号,则手机模块处于等待状态。经验证,在无人操控下项目完成预期功能。该设计实现的自动检测及自动短信功能可用于安防、自动刹车、自动避障等方面。

On the basis of the ultrasonic sensor, the distance detection scheme was designed to realize the functions of auto- matic detection, automatic judgment and SMS automatic notification. The distance is detected with the ultrasonic wave, and the acquisition signal is given in the design. The single chip microcomputer is used to process the acquired signal, and adjust the working state of the mobile phone module according to the acquisition result. If the amplitude of the acquired signal is lower than that of the standard signal, the mobile phone module will work, otherwise the mobile phone module will be in the waiting state. The project can realize the expected function under the unmanned control by means of verification. The automatic detec- tion and automatic SMS notification functions of this design can be used in security, automatic braking, automatic obstacle avoidance, etc.
