摘 要
 
 本說明書介紹了一種移動信號無線發射裝置，該裝置通過人手在空間移動的位置和動作來代替計算機的鼠標去控制計算機。
 該裝置以人手的空間移動位置和動作為檢測對象，使計算機的鼠標指針能跟隨手的空間位置移動，并能根據手的動作操縱計算機。該裝置采用無線傳送方式，使用USB接口與計算機聯結。
 該設計由四部分組成：第一部分為空間相對位移檢測，該部分采用光纖傳感器陀螺儀輸出兩路信號。第二部分為信號檢測、處理部分，通過AT89C2051單片機對兩路信號的檢測，從而判斷出移動方向。第三部分為無線數字收發電路設計，發射電路采用TX4915單片集成AM/ASK發射器，接收電路采用RX3400單片集成ASK無線電接收芯片，從而完成數字信號無線發射接收功能。第四部分為USB接口部分，該部分采用CY7C63000芯片。
 該移動信號無線發射裝置以AT89C2051單片機為核心，采用ASK調制解調方式實現空間相對位移數據的無線傳送；接口采用標準的USB通用串行接口；電路的設計以集成電路設計為主；軟件設計保證鼠標不用時工作于等待工作方式。因而，該裝置通用性強，體積小，功耗低。

THE DESIGN OF WIRELESS EMITTER OF SHIFTING SIGNALS
 
Abstract

 This direction introduces a wireless emitter of some certain shifting signals. And this equipment can control the computer through tracking hand’s position in the space and the actions instead of the mouse.
 This equipment set the position of the hand in the space and its action as the objects, making it possible for the mouse’s finger to follow the position then operating the computer according to the actions. The equipment is designed wireless and connected with the computer by UBS access.
 The equipment consists of four parts. The first part tests the relative shift of hands in the space, and sends two routs of signals through the gyroscope of the fiber sensor. The second part examines the signals through AT89C2051, identifying the direction of the movement. The third part designs the wireless digital circuit for sending or receiving the signals. The sending circuit is composed as AM/ASK emitter by TX4915 single-chip microcomputer and the receiving circuit as ASK radio chip by RX3400 single-chip microcomputer, accomplishing the function of sending or reviving digital signals. The last part is the USB access, which adopts the CY7C63000 chip.
 The wireless emitter of shifting signals adopts AT89C2051 as the core chip and ASK modem to transmit the data of the mouse. Meanwhile the current standard USB series access and adopted and the integrated circuit (IC) is designed as the main circuit. Finally the software ensure that the mouse will work under the waiting mode if it is not used at the time.
 In brief, the equipment designed has the advantages of good versatility, small bulk and low power dissipation.
