通过超声波测距并通过模块NRF24L01模块设计的一款汽车倒车时的声光报警系统。本设计的总框架具体分为两个主要部分,一是距离测量部分、二是主控部分的接收数据警报部分

摘  要超声波测距在现实生产、生活中的逐渐起到了举足轻重的地位。本次设计的基于51单片机倒车雷达系统就是很好的设计实例,并且增加了无线数据传输的功能,实际意义更加明显。随着数年来无线数据传输飞快的进步提升,无线传输也逐渐深入到我们的现实生产当中,具有无线控制以及传送功能的倒车雷达系统是很有必要的。68869

本设计就是通过超声波测距并通过模块NRF24L01模块设计的一款汽车倒车时的声光报警系统。本设计的总框架具体分为两个主要部分,一是距离测量部分、二是主控部分的接收数据警报部分。距离测量部分通过获取到测距功能部分所测得的实际距离数据,在此数据获取之后,利用NRF24L01芯片将数据传送给主控模块。系统的主控部分用LCD1602显示超声波测距所传回的距离数据。此外,主控部分可以通过按键来改变系统的报警值。当实测距离低于手动设置的安全距离时,主控部分的蜂鸣器鸣响和二极管点亮以实现报警功能。设计结尾部分,要对设计进行误差分析并作出适当的调整、调试,确保本设计能够有较大程度的安全性。

Reversing Radar System Based on Single Chip

Abstract

Ultrasonic Ranging gradually played a pivotal role in real production and life. in this design Reversing radar system based on single chip is a good design example and the design increased wireless data transmission function, the actual meaning is more obvious. Recently, wireless transport technology has a great progress, wireless transmission gradually deep into our real production of which reversing radar system with wireless control and transport functions is necessary.

The design is sound and light alarm system using ultrasonic ranging and data transmission when a car reversing. The system has two main modules in totally, the first part distance measurement module, the other is that the master sound and light alarm module receiving the data portion. Measurement module acquires the measurement data, with ultrasonic ranging module. After data acquisition, processing and transmits the data to the master module through NRF24L01 wireless transmitter. Master module displays the distance data that ranging module returned modules by LCD1602. In addition, the main control section can change the alarm value of the system through the key. When the measured distance is less than the safe distance that set manually, the buzzer will sound and the diode will light. In the end of design, I have to do some error analysis and make appropriate adjustments, commissioning, to ensure that the design can have a greater degree of security.

Key Words:  single-chip  wireless transmission  ultrasonic distance measurement
