1、本智能停车场管理系统之车位引导具有以下功能：（基于51单片机）u 车位自动引导功能（12864显示屏和点阵屏的使用）总控制器和区域控制器会实时的统计停车场总的停车位和每一个区域的停车位空闲状态，然后通过显示屏显示出来，所以车主在驶入停车场的整个过程中都可以得到指引，顺利的找到一条最方便快接的路径，把车子驶入车位。u 车位自动统计功能（红外线和超声波传感器的使用）每一个车位上方都有一个超声波探测器，他能够实时的监测车位上车子的状况，并且将这些状况通过双交线传输到系统的控制器里面，控制器具有数据运算功能，通过运算就可以知道整个车库的使用状况，然后通过车位显示屏显示出整个停车场有多少空车位，每一个停

2、车区域有多少空车位。此代码大多都有文字说明，排序合理，有少少基础的一看就能懂的。附录：源代码/*/* Name: 智能停车场管理系统之车位引导 b*/* #include #include #define uchar unsigned char#define uint unsigned int/引脚定义 sbit RX = P3 3;/超声波模块ECH0 sbit TX = P3 4;/超声波模块TRIGsbit CS = P3 5;/12864片选 高电平有效 sbit SID = P3 6;/12864数据 sbit SCLK = P3 7;/12864时钟sbit H_1=P10; /定
