51单片机公园游客人数自动记录系统的设计+电路图

摘要人口众多是我国的基本国情之一。每当假期“黄金周”，各景区井喷的客流对各地旅游和景区管理部门来说是相当棘手的。准确掌握公园、景区内实时人数，以便对人流的控制进行科学决策，防范安全事故，显得尤为重要。因此，研究开发一套结构简约、成本低廉、功能多样、操作简便的公园人数自动记录与显示系统便具有重大的现实意义。本设计是以51单片机为基础，配以红外光电传感器、LCD显示模块、蜂鸣器、通信协议转换芯片、时钟芯片、温度传感器芯片等，利用Proteus 和Keil等开发工具、C和Visual Basic等编程语言，研究开发的一套具备与后台计算机通信功能的兼具日期、时间、温度显示功能的低复杂度、低成本、多功能、高可靠性的公园人数自动记录系统。本文主要介绍了本设计的背景、研究方法、设计流程、软硬件设计思路和具体设计方案、仿真结果、PCB设计制作等，并在最后对设计成品进行了集中展示。59649

Title Design of Automatic Counter and Recorder for the Number of Visitors
Abstract Population is one of China's basic national conditions. Whenever the "Golden Week", the crowds always give great pressure on tourism and scenic administrations. Exact information of the number of visitors is very important to accident prevention. Therefore, to design a set to count the number of visitors easily will have great significance. This design aims to create a simple, low-cost, multi-function and reliable counter based on MCS-51 MCU, together with photoelectric sensor, LCD1602, buzzer, MAX485, DS1302, DS18B20 and equipped with the function of communicating between MCU and PC and displaying date, time and temperature. It uses C language to write MCU program and Proteus as a development tool to simulate the system and design the PCB. This paper describes the background, research methods, design processes, software and hardware design ideas and programs, simulation and PCB production processes of this design. Finally, the finished product is shown in the end of the paper.
