毕业设计(论文)题 目 基于单片机的超声波测距系统的设计 学生姓名 学 号 所在院系 物理与电信工程学院 专业班级 电子信息科学与技术 ( 电信 1201) 指导老师 完成地点 陕西理工学院博远楼 2025 年 5 月 26 日基于单片机的超声波测距系统的设计（陕西理工学院物电学院电子信息科学与技术专业 2025 级 1 班，陕西 汉中 723000）指导老师： [摘要]此设计对基于单片机控制的超声波测距仪原理进行了介绍：用 STC89C51 控制定时器发出超声波脉冲并开始计时，得到超声波从发射到接收的所需要的时间，来得到测量的距离。在液晶屏上显示出测量距离。单片机对各探头进行综合分析，从而实现超声波测距功能。以此为基础，设计了此系统的总体方案，最后以硬件和软件相结合的形式实现了各个功能模块。此系统的优点有：测距准确度高、可读性强、易控制、工作可靠和流程清楚等。 [关键词]STC89C51，超声波，测距Design of ultrasonic distance measurement system based on single chip microcomputer（Grade12,Class01,Major Electronic Information Science and Technology,School of Physics and Telecommunication Engineering,Shaanxi University of Technology, Hanzhong,723000 Shaanxi）Tutor: J Abstract : The design of based on single-chip microcomputer control ultrasonic distance measurement principle were introduced: use STC89C51 to control the timer sends out ultrasonic pulse and the beginning of time, ultrasound from the transmitter to receive the needed time to measure the distance. Display the measuring distance on the LCD screen.Single chip microcomputer to carry out the comprehensive analysis of the probe, so as to realize the function of ultrasonic distance measurement. Based on this, the overall scheme of the system is designed, and the function modules are realized by the combination of hardware and software. Part of the program flow chart and hardware circuit diagram, also gives the principle of the circuit, the system structure and the design of the program. This system ...
