自动泊车系统 摘 要

随着车辆的普及度、保有量越来越高，街道、小区、公路、停车场等拥挤不堪，人们对车辆的可操作性和智能性也提出了更多的要求，所以智能的自动泊车的研发迫在眉睫。本设计以蓝牙模块与单片机最小系统通过串口相连接，并与电脑端蓝牙连接实现下位机与上位机之间的通信过程,从而实现自动泊车的功能。

本设计由上位机、蓝牙模块、STC15F2K61S2单片机最小系统、GY-26电子指南针模块、光电避障模块、超声波模块、电机驱动模块、舵机组成系统。主要包括以下几个方面：第一，硬件电路设计，硬件电路通过Altium Designer软件进行硬件电路设计，主要包括包括电源系统和单片机最小系统，第二，STC15F2K61S2单片机最小系统设计，最小系统可以实现超声波数据、光电避障模块数据、电子指南针模块数据的接受，由上位机端发送命名实现对小车的相应控制。第三，上位机软件设计，上位机由C Sharp语言在Visual Studio 2010平台编写，主要实现对由下位机说发送的数据进行处理并实时显示出来的，并且对自动泊车系统进行整体控制，通过蓝牙向单片机最小系统发送数据，单片机接收到数据后控制小车完成侧位泊车或倒车入库动作。

Automatic parking system

Abstract

With the popularization of vehicle, retains the quantity is more and more high, streets, communities, roads, parking lots and other crowded. People of the vehicle can also put forward more requirements for the operation and intelligent, so the research and development of intelligent automatic parking is imminent. This design takes the Bluetooth module and the microcontroller smallest system through the serial port, and realizes the communication process between the lower computer and the upper computer with the Bluetooth connection of the computer terminal.

The design of the PC and Bluetooth module, STC15F2K61S2 MCU minimum system, GY-26 electronic compass module, photoelectric obstacle avoidance module, ultrasonic module, motor drive module, servo system. Mainly includes the following aspects: first, hardware circuit design, hardware circuit through Altium designer software were hardware circuit design, including including power supply system and the smallest single-chip system. Second, STC15F2K61S2 smallest single-chip system design, the minimum system can realize ultrasonic data, photoelectric obstacle avoidance module data, electronic compass module data received, sent by the host computer end named the corresponding control of the car.Third, PC software design and PC by C sharp language on the platform of Visual Studio 2010 prepared, mainly to achieve by the slave computer said transmitted data for processing and real-time display, and the automatic parking system integrated control, via Bluetooth to send data to the MCU minimum system, MCU receives the data control the car lateral parking or reversing storage action.

Key words: PC, minimum single-chip microcomputer, automatic parking
