任务摘要
当今社会，交通压力不断增加，智能停车场管理系统是人们对便捷高效交通的一种追求。本智能停车场管理系统运用RFID技术，采用STC8H8K64U单片机、RC522、串口屏、光电传感器实现系统设计的基本功能要求。用光电传感器检测车位信号；用RC522实现读卡，获取卡片信息，检测卡片有效性；用LCD串口屏幕显示系统时间日期、持卡人姓名、总停车位、可用停车位、距离最近车位、停车时间和收费以及卡片无效提醒；用单片机控制舵机转动，代表栏杆抬起和落下；用单片机实现从卡片中自动扣费，当车辆进出场时使用语音提醒。本设计主要应用于小区、学校等场所，给人们提供便捷高效地停车服务。
在设计该智能停车场管理系统时，使用到了软件和硬件知识，包括原理的设计、各个模块的连接、RC522模块的使用、单片机程序设计、显示屏界面设计。通过设计、调整和调试后，本设计大致完成了以下指标：
（1）实现了光电传感器检测车位信号；
（2）实现了RC522读取卡片，检测卡片有效性；
（3）实现了LCD串口屏幕显示系统时间日期、持卡人姓名、总停车位、可用停车位、距离最近车位、停车时间和收费以及卡片无效提醒；
（4）实现了车辆入场出场时语音播报提醒；
（5）实现了单片机控制舵机转动；
（6）实现了单片机从卡片自动扣费。
实物
本系统使用光电传感器做车位检测，其体积小，成本低，使用简单，适合IO引脚有限制的设计。
对比分析，超声波传感器虽然精度较高，但安装位置固定，超声波散射和发射容易引起误判导致检测错误，而光电传感器虽精度没有超声波传感器好，但稳定性较好，在室内停车场中受环境因素影响小，所以综合考虑下，采用光电传感器。

单片机最小系统板：
使用STC8H8V64U单片机作为智能停车场管理系统的核心板，STC8H8V64U有64个I/O口，具有超高速8051内核。由于该系统使用到的I/O口较少，如果使用STM32单片机作为核心板则体现不出性价比从而造成资源的浪费。STC8H8V64U不需要外部晶振，运行频率45MHZ。所以综合功能要求、性价比等方面，该设计选择使用性价比较高的STC8H8V64U单片机作为核心板。
原理图
系统架构
本系统设计的智能停车场管理系统主要由STC8H8K64U单片机、光电传感器、LCD串口屏幕、RC522射频模块、语音播报模块、DS1302时钟模块、舵机和对应驱动板等多个元器件组成，总框图如图所示。在本设计中，使用舵机充当栏杆，使用光电传感器代替停车位。本设计虚拟设置了100个停车位，但由于设计区域的限制，实际用了9个光电传感器来代替。
模块讲解
语音模块
语音模块使用的是SYN6288中文语音合成芯片，其可以接受待合成的文本数据，实现文本到语音的转换，语音合成效果较好。语音播报模块电路如图所示。语音模块使用串口进行数据通信，将要发送的数据使用串口发送给模块即可命令模块进行播放，但要注意发送字节长度有限。

串口屏
本设计采用的是2.4寸的LCD串口显示屏，点阵分辨率为240*320，能够在屏幕上的任意位置显示图片及任意的图形。该模块主要通过RXD、TXD对数据进行异步通讯接收和发送，在本设计中，显示模块主要是接收单片机STC8H给出的数据指令。采用LCD显示模块实现单片机对一些数据的显示，智能停车场管理系统可以直接在LCD显示屏上看到系统的时间、总停车位、剩余停车位以及卡片信息等内容。
