摘要

本文详细地介绍了无线电子防丢器的开发过程。无线电子防丢器的从机通过判断接收回来的信号确定主机的存在，然后返回一个信号给主机。主机判断从机是否返回信号或者信号的强弱来确定从机是否丢失，从而发出报警声，提醒使用者的注意。主机还可以控制从机发出报警声，以确定从机的位置进行寻回。

本文所研究开发的无线电子防丢器是基于MSP430单片机控制的CC2500无线模块的一种应用。

首先，本文阐述了对无线电子防丢器开发所需要的基础知识，有：无线传输技术，通信协议，CPU模块原理，RF模块原理。

然后，进行芯片（CPU,RF芯片）的选择；接着就是基本功能的实现（一对一通信）。

最后做出成品并进行各项数据的测试，与理想的成品进行比较，找出不足之处并进行改良，最终完成整个开发的过程。

Abstract

wireless electronic anti-lost device development process is introduced in this thesis.. Wireless electronic anti-lost device to receive back from the machine by determining the presence of the signal to determine the host, and then returns a signal to the host. Host to determine whether the return signal from the machine or the signal strength to determine whether the loss from the machine, which sound an alarm to remind the user's attention. Host can also control an alarm sound from the machine to determine the location from the machine located.

Research and development in this paper a wireless electronic anti-lost alarm is based on the MSP430 MCU's CC2500 radio module, an application.

First of all, in this paper, the wireless electronic anti-lost alarm basic knowledge required to develop, include: wireless transmission technology, communication protocols, CPU module theory, RF module principle.

Then, the chips (CPU, RF chip) choice; then is the basic function of the realization(one to one communication).

Finally, the data to make the finished product and conduct tests to compare with the ideal product to identify shortcomings and make improvements, and ultimately complete the entire development process.
