摘要矿井运输是煤矿生产作业中的一个重要部分，在煤矿安全事故中运输事故占有较大比例。因此非常需要设计一个行人检测报警系统，以此来保证矿井运输的安全，从而提高煤矿生产的整体安全性。67754
针对机车的具体运输情况，我们设计开发了基于ATmega128单片机的行人检测系统。此系统能够有效检测车辆前方及两侧的障碍，并将具体信息以语音及图像的方式告知相关人员。主要承担工作和研究如下：
① 了解整个系统及其中各模块的主要功能，掌握具体芯片的特点及使用。
② 对ATmega128单片机进行认识了解，熟悉其硬件接口和软件开发工具，掌握C语言程序设计和单片机开发流程。
③ 研究分析CA320240B液晶屏及其SED1335控制器，针对系统需求编写LCD显示驱动来显示车辆及障碍物信息，并进行相关调试。

Title Railway Car Pedestrain Detection Alarm System Based on ATmega128 Single-chip Microcomputer
Abstract
The mine transportation is an important part of coal mine production.Transportation accidents have a large proportion in coal mine safety accidents.So it is really necessary to design a pedestrain monitoring alarm system to ensure the safety of the mine transportation,so as to improve the overall security of coal mine production.
According to the specific transport condition,we designed and developed the pedestrain detection system based on the ATmega128 single-chip microcomputer.this system can effectively detect the obstacle in front and on either side of the vehicle and put the information the people in the form of voice or image. The main research and work are as follows:
① Known the main function of the whole system and each module.Mastered the characteristics and using methods of each chip.
② Famililar with the ATmega128 single-chip computer ,its hardware interface and software development tools.
Researched and analysised the CA320240B LCD and the SED1335 LCD controller.Written the LCD dirver according to system requirements to display the information of the vehicle and obstacle, tested and debuged the program.
Keywords distance measurement single chip microcomputer LCD dirver programming design
