1、 I 毕业设计（论文） 基于以太网的自动寻迹小车 学院（系） ： 专业班级： 学生姓名： 指导教师： II 摘要摘要 为充分利用远程资源，实现远程控制设备，设计网络小车控制系统，通过太网控制 小车的基本动作。 本系统采用 AT89S52 单片机作为控制系统的核心， 采用直流电机作为 电动车驱动电机，通过 PC 上位机利用以太网向小车单片机发送指令，控制小车实现前 进、左转、右转、后退、停止以及自动寻迹功能，从而实现了基于以太网的远程控制。 设计难点是数据的发送和接收，以及服务器端设备的控制部分。数据由 PC 机网络 端口发出，经以太网传送以后利用周立功公司的 ZNE-100TL 模块对信息进行
2、转换，最 终处理为 RS-232 串口数据，达到控制设备的目的。测试结果理想。 关键字：以太网；电动车；直流电机；关键字：以太网；电动车；直流电机；AT89S52 AT89S52 III ABSTRACT To capitalize on the remote resources and implement the control equipment on the net, the system is controlled to achive the vehicles basic movements by the network based on the ethernet. Employed
3、AT89S52 Micro Controller Unit (MCU) as the core system controller, direct current motors used as electric cars drive, data is sent by the Personal Computers (PC) via ethernet as the commands to make the car achieve basic movements, such as turnning left and right, rewinding, stopping and running fol
4、lowing the white line. The system realizes the remote controlling based on the ethernet. The key technology of the design is the datas sending and receiving, and the controlling of the server devices. Data is sent by the PC network from the ethernet port, and then is transmitted by ZNE-100TL module of ZLG company, processed to be acceptable for the RS -232 serial data port. The result of the test is good. Keywords: Ethernet; Electric Car; DC_Motor;A
