芃蒄蚀羇腿蒃螂膂蒈蒂袄羅 基于单片机的智能停车场管理系统设计—毕业设计 关键词:智能管理,车牌识别,车位诱导,车辆检测 DESIGN OF THE PARKING INTELLIGENT MANAGEMENT SYSTEM ABSTRACT This design is a type of single chip microcomputer AT89C51 as the controller chip intelligent parking system, mainly is aims at the vehicle induction and vehicle detection system. The system of pass in and out of the parking lot coils vehicle detection and control brake rod machine automatic ups and downs, and have parking display and audio function. The system with IC card and image processing device can monitor form a complete set of intelligent parking system, so as to realize intelligent management of large parking lot. In the design of the vehicle detection is the key said of design principle, and the corresponding hardware interface circuit and software programming essentials. In general the system basically has the following characteristics: remote sensing reading card, without stopping, speed, high efficiency; The computer management, scientific and efficient; Simplify the vehicle pass in and out management procedures, and safe; System equipment less investment, construction period is short, the effect is remarkable. This design emphasis of intelligent parking system lies in the parking places induction and vehicle detection. KEY WORDS: Intelligent Management,Intelligent Charging, License Plate Identification, Parking Iinduction and Vehicle Detection. 目 录 前 言 1 第1章 绪论 3 1.1 课题设计目的和发展趋势 3 1.1.1 课题研究目的及实际意义 3 1.1.2 智能停车场管理系统发展概况及趋势 3 1.2 课题设计思想 4 第2章 智能停车场管理系统概述 5 2.1 射频技术(RFID)概述 5 2.1.1 射频识别系统的构成 6 2.1.2 射频系统基本工作流程图 6 2.2 车牌识别技术 7 2.2.1 车牌自动识别系统原理 8 2.2.2 牌照号码、颜色识别 9 2.3 车位诱导和车辆检测系统概述 10 2.3.1 车位诱导和车位显示 11 2.3.2 超声波测距原理 12 2.3.3 车辆检测 13 2.4 小区停车计费系统概述 14 2.4.1 计费系统概述 14 2.4.2 计费系统的工作原理及特点 14 2.5 进出口识别系统概述 17 第3章 车位诱导车辆检测系统硬件设计 19 3.1 停车场系统 19 3.2 系统总体原理 20 3.2.1 车辆检测 20 3.2.2 车位诱导和车位显示 21 3.2.3 其他控制部分 21 3.3 车辆检测系统硬件设计 22 3.3.1 锁相环路工作原理 22 3.3.2 信号输入电路的设计 23 3.3.3 复位电路的设计 24 第4章 系统软件设计 25 4.1 程序流程图 25 4.2 设计要点 26
