江阴职业技术学院 毕业论文 课题：基于PTR2000无线数据传输 的设计 专 业 学生姓名 班 级 学 号 指导教师 完成日期 摘 要 本文设计了一个无线数据传输系统，此系统由发送单元和接收单元构成，发送单元的单片机(MCU),通过无线数据收发模块PTR2000发送给接收单元的PTR2000模块；通过无线数据收发模块PTR2000接收发送单元发送过来的数据，通过MAX232芯片传送给计算机。本文详细分析了上述实验原理，并给出了主要程序代码。 单片机的无线数据收发模块PTR2000的组合，形成单片机的无线数据传输系统，与微机进行无线数据传输。无线技术正以一种快速的速度进入许多产品，它与有线相比主要有成本低，携带方便，省去有线布线的烦恼；特别适用于手持设备的通信、电池供电设备、遥控、遥测、小型无线网络、无线抄表、门禁系统、小区传呼、工业数据采集系统、无线标签身份识别、非接触RF智能卡、小型无线数据终端、安全防火系统、无线遥控系统、生物信号采集、水文气象监控、机器人控制、无线232数据通信、无线数字语音、数字图像传输、智能小区停车收费、银行智能回单系统等。本文以PTR2000无线收发模块为例，详细介绍无线收发模块与单片机的硬件接口设计，无线模块和PC机的硬件接口设计，无线通信协议以及相关软件设计。 Abstract This paper describes the design of a system,which detailed introduce wileless data transmission.The system consists of sending and receiving modules.The MCU in the sending modules,data through a wileless data transceiver module PTR2000 send to the receiver module PTR2000 module. Wileless data transceiver module PTR2000 receiving sending unit sent over the temperature data,then through MAX232 module transmitted to the computer.In this paper,a detailed analysis of the principles,and gives the main programcodes. MCU and wileless data transceiver module PTR2000 composition formed SCM wileless data transmission system and the computer for wileless data transmission. Wilelee technologies are in a fast pace to enter many products,and compared it with the main cable is low cost and easy to carry,save the trouble of having cable wiring; Particularly applicable to handheld device communications,battery-powered equipment,remote control,telemetry,small wileless network, wileless meter reading, door lock systems,paging district,industrial data acquisition system, wileless identification label,security,fire protection systems, wileless remote control system, biological signal acquisition,hydro-meteorological monitoring,robot control,232 wileless data communication, wileless digital voice, digital image transmission
