摘 要
本说明书介绍了一种移动信号无线发射装置，该装置通过人手在空间移动的位置和动作来代替计算机的鼠标去控制计算机。
该装置以人手的空间移动位置和动作为检测对象，使计算机的鼠标指针能跟随手的空间位置移动，并能根据手的动作操纵计算机。该装置采用无线传送方式，使用USB接口与计算机联结。
该设计由四部分组成：第一部分为空间相对位移检测，该部分采用光纤传感器陀螺仪输出两路信号。第二部分为信号检测、处理部分，通过AT89C2051单片机对两路信号的检测，从而判断出移动方向。第三部分为无线数字收发电路设计，发射电路采用TX4915单片集成AM/ASK发射器，接收电路采用RX3400单片集成ASK无线电接收芯片，从而完成数字信号无线发射接收功能。第四部分为USB接口部分，该部分采用CY7C63000芯片。
该移动信号无线发射装置以AT89C2051单片机为核心，采用ASK调制解调方式实现空间相对位移数据的无线传送；接口采用标准的USB通用串行接口；电路的设计以集成电路设计为主；软件设计保证鼠标不用时工作于等待工作方式。因而，该装置通用性强，体积小，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.
