摘要:鼠标自出现以来经历了从机械鼠标到光学鼠标,从有线鼠标到无线鼠标的过渡。文中设计的无线鼠标通信系统模块包含发射电路和接收电路两部分,在发射电路模块中系统将采集到的模拟信号经过数模转换,转换成可供信道传输的数字信号,再经过编码器MC145026编码之后传输给发射芯片TDC1808进行发射
接收芯片TDC1809负责接收信息,将接收到的信号传输给译码器MC145027进行译码,将译码后的信息传输给计算机,计算机自动完成相应的操作,然后不断的循环。经测试,采用该设计的鼠标不仅具有普通鼠标的全部功能,还可以远距离的灵活操纵鼠标。
TDC1808是微型射频无线发射模块,发射频率在250M~350MHz范围内,可以直接外接各种调制信号,可靠发射距离能达到120m。TDC1808/TDC1809采用内置天线,可传送数字信号或模拟信号,适用于各种无线遥控装置,具有体积小,遥控距离远,抗干扰能力强等特点。
在设计中采用编/解码器MC145026/MC145027变换信号使得在与计算机连接过程中有了较简单和清晰的方案。无须改动鼠标及计算机,无须安装额外的鼠标驱动软件,原有鼠标的所有功能亦能正常使用。

Design of the receive and transmit module
about the wireless mouse
Abstract:The mouse has experienced from mechanical mouse to optical mouse since appeared, the transition from wired mouse to wireless mouse.As the wireless mouse designed in this paper, its communication system includes two parts of the modules covering emission circuit and receiving circuit . Over the emission circuit module,the system converts the collected analog signals to digital signals of channel transmission through D/A , the digital signals encoded after coder MC145026 transfer to emission circuit module TDC1808 to launch.
Receiving circuit module TDC1809 is responsible for receiving information,It transmits the received signals to the decoder MC145027 to decode,and transfers the decoded information to the computer . The computer automatically completes the corresponding action,Followed by continuous cycle.,After the test,The circuit not only has all functions of the normal mouse, but can also flexibly manipulate the mouse over a long distance.
TDC1808 is miniature RF wireless transmitting module,Transmission frequency at the range of 250M~350MHZit can directly add-ins a veriety of modulation signalAnd have a reliable transmission distance up to 120 m. TDC1808/TDC1809 built-in antenna, it can transfer the digital or analog signals, and applicable to all kinds of wireless remote control device .with small, remote control distance, strong anti-interference ability, and other characteristics.mc145026/mc145027 knitted / decoder used in the design can transforms the signal connected to the computer in the process simpler and clearer proposal. There are no need to change the mouse and computer, also do not need to install additional Mouse driver software. All the function of the original mouse can use normal.
