摘要：鼠標(biāo)自出現(xiàn)以來(lái)經(jīng)歷了從機(jī)械鼠標(biāo)到光學(xué)鼠標(biāo)，從有線鼠標(biāo)到無(wú)線鼠標(biāo)的過(guò)渡。文中設(shè)計(jì)的無(wú)線鼠標(biāo)通信系統(tǒng)模塊包含發(fā)射電路和接收電路兩部分，在發(fā)射電路模塊中系統(tǒng)將采集到的模擬信號(hào)經(jīng)過(guò)數(shù)模轉(zhuǎn)換,轉(zhuǎn)換成可供信道傳輸?shù)臄?shù)字信號(hào)，再經(jīng)過(guò)編碼器MC145026編碼之后傳輸給發(fā)射芯片TDC1808進(jìn)行發(fā)射
接收芯片TDC1809負(fù)責(zé)接收信息，將接收到的信號(hào)傳輸給譯碼器MC145027進(jìn)行譯碼，將譯碼后的信息傳輸給計(jì)算機(jī)，計(jì)算機(jī)自動(dòng)完成相應(yīng)的操作，然后不斷的循環(huán)。經(jīng)測(cè)試，采用該設(shè)計(jì)的鼠標(biāo)不僅具有普通鼠標(biāo)的全部功能，還可以遠(yuǎn)距離的靈活操縱鼠標(biāo)。
TDC1808是微型射頻無(wú)線發(fā)射模塊，發(fā)射頻率在250M～350MHz范圍內(nèi)，可以直接外接各種調(diào)制信號(hào)，可靠發(fā)射距離能達(dá)到120m。TDC1808/TDC1809采用內(nèi)置天線,可傳送數(shù)字信號(hào)或模擬信號(hào),適用于各種無(wú)線遙控裝置,具有體積小,遙控距離遠(yuǎn),抗干擾能力強(qiáng)等特點(diǎn)。
在設(shè)計(jì)中采用編/解碼器MC145026/MC145027變換信號(hào)使得在與計(jì)算機(jī)連接過(guò)程中有了較簡(jiǎn)單和清晰的方案。無(wú)須改動(dòng)鼠標(biāo)及計(jì)算機(jī)，無(wú)須安裝額外的鼠標(biāo)驅(qū)動(dòng)軟件，原有鼠標(biāo)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.
