摘要 红外无线遥控鼠标器主要由发射和接收两部分组成，发射端采用SC9148B红外发射芯片及其发射电路，通过把红外无线遥控鼠标器的各控制键（鼠标左、右、上、下移动键、左右键、向下及向上翻页键）进行编码，然后通过38KHz红外载波以原码和重发码的形式连续对外发送，以防止数据在传送过程中出现错误。在接收部分通过红外接收头校正放大之后由P87LPC762芯片解码，由于双重码的传送形式，大大增加数据的准确性，把串行数字信号转化为并行信号，并产生相应的控制指令，然后通过HT82K95E USB OTP/Mask MCU芯片，把控制指令转化成计算机USB口能够接收的信号然后通过USB口向计算机发送无线遥控鼠标的各个控制功能指令。最终达到红外线遥控鼠标器的各种控制功能。同时发射部分还有激光发射电路，使红外无线鼠标遥控器具有激光笔的功能。 这就使红外无线遥控鼠标器成为一个完美的多功能的多媒体播放外接工具。通过调试验证其系统稳定，通信可靠。最后论文总结了在无线鼠标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 Infrared wireless mouse remote control mainly by transmitting and receiving composed of two parts, the transmitter used SC9148B infrared emission circuit chip and its launch of the wireless infrared remote control of the mouse control button (the mouse left、 right、up and down move’s button, the left and right button, flip up and down) encoded, and then after 38 KHz through infrared carrier to the original code and re-issued in the form of code for external transmission, to prevent the transmission of data in the process of error in the receiving part through red Larger, after receiving the first correction by the P87LPC762 decoder chip, code form of a double transmission greatly increase the accuracy of the data, the serial digital signals into a parallel signal, and generate corresponding control instructions, and then through HT82K95E USB OTP / Mask MCU chip , The control commands into a computer USB port that can receive the signal through the USB port and then sent to the wireless computer mouse functions of the various commands. And ultimately achieving the infrared remote control for all kinds of mouse control. At the same time there are parts of the laser firing circuit so that the infrared wireless mouse remote control with Laser pen in function, so that the infrared wireless mouse remote control as a perfect multi-functional multimedia player external tool. Commissioning verification through its system is stable, reliable communications. Summed up the final papers in the infrared wireless mouse remo
