毕设论文-无线鼠标接收器研究设计.doc

摘 要 鼠标是人们日常使用的电脑外设，其技术的发展备受瞩目。而随着工作环境和需求的不断变化，人们越来越需要一种具备无线功能和悬空遥控功能的鼠标，它不依赖于平面，没有连线的距离限制。同时，在鼠标的发展中，如何缩小鼠标的体积，降低鼠标的功耗也越来越被人们所关注。无线鼠标则是电脑周边器件与无线通信技术的完美结合物。 通常，鼠标通过PS2插口或者USB接口以有线的方式将移动的距离和方向转换成脉冲信号传送给PC。根据鼠标的工作原理和协议，利用S2鼠标和315M无线发射接收模块，配合PC串口，制作无线串口鼠标。 本文在分析了无线鼠标的工作原理之后，将无线鼠标的设计主要分为两部分。一部分是无线通信，使用无线收发进行无线发送和接收，对该芯片进行控制完成信息的无线传递功能。另一部分为接收器与计算机间的通信，将接收器接收到的信号在单片机的控制下通过PL2303HX这类USB转UART芯片传递给PC机并让PC识别出相应的操作。后面的论文总结了在无线鼠标接收器研究设计中的工作，提出了下一步需要完善和解决的问题。 ABSTRACT The mouse is daily use of computer peripherals， and its technology focus of attention. And with the work environment and the needs of constantly changing，people are more and more need a wireless function and impending function of remotde control of the mouse. It doesnt depend on the plane， no attachment distance limit.In the meantime，the development of the mouse how to reduce the volume of narrowing the mouse， the power consumption is also more and more be mouse concern for people. Wireless mouse is computer peripheral devices and the perfect combination of wireless communication technology things. General，The mouse through the PS/2 or USB cable way will move in the distance and direction convert pulse signals to the PC. According to the work principle and agreement mouse， using the S2 mouse and 315M wireless transmitting receiving module， cooperate， making wireless PC serial serial mouse.Based on the analysis of the wireless mouse works ，wireless mouse is mainly divided into two parts.Part of is wireless communication ，Using wireless transceiver for wireless send and receive，The chips for control of the wireless transfer function complete information.Another part of is Receiver and computer communications ，then receiver received signals Under the control of the processor get through PL2303HX this kind of USB/UART chip to pass to the PC And let PC identify the corresponding operation .Behind the paper summarizes the research in wireless mouse receiver design work， are put forward need to improve and solve pr
