摘要

蓝牙属于短距离内进行无线控制和收发的通信技术，伴随着科技的飞跃性发展，也让蓝牙找到了发展的空间，它可以代替和取代落后的数字化硬件设备之间繁琐的电缆连接。在蓝牙创造的初期，没有人预料到蓝牙会有如此大的潜力和前景，而现在的发展也是完全超出了我们的预期，因为蓝牙的安全性高，制造成本低廉和所消耗的功率也是同类产品中最低的，所以被很多人使用，越来越受到了广大消费者的欢迎，基于蓝牙技术的产品也在不断的更新和投入市场。

由于蓝牙工作频率与无线使用Wi-Fi，在未授权的2.4GHz ISM频段重叠无绳电话和微波，在家庭环境中使用蓝牙遥控装置可能会缩短通信时间延迟和电池寿命的问题，因为它采用了跳频扩频是易受干扰避免机制。

我的毕业设计是以89C52单片机为主控芯片，毕业设计的系统是简易蓝牙遥控系统，要在有效范围内（最少5米）实现无线蓝牙的接收和发送，遥控对象为4个（LED），使用11.O592MHz的晶振，LD3320语音模块以及89C51单片机进行程序的控制，本设计主要有两部分组成，一个是接收部分，另一个是发送部分，所设计的两部分电路完全一样，自行选择分配。

Remote control system based on 52single chip Bluetooth

Abstract

Bluetooth is a short distance communication technology for wireless control and transceiver, accompanied by rapid development of science and technology, also let the Bluetooth to find space for development, it can replace and replace the complicated cable connection between digital equipment and backward. In the early days of the Bluetooth creation, nobody expected that Bluetooth has potential and prospects of so much, and now the development is completely beyond our expectations, because the security of Bluetooth's high, low manufacturing cost and power consumption are similar products in the lowest, so many people use, more and more. The majority of consumers, Bluetooth products are constantly updated and put into the market based on.

Because Bluetooth and Wi-Fi wireless frequency overlap, cordless phones and microwave in the unlicensed 2.4GHz band ISM, Bluetooth remote control device used in the home environment may reduce the communication time delay and battery life, because it uses a frequency hopping spread spectrum is susceptible to interference avoidance mechanism.

I graduated from the design is based on 89C52 single chip microcomputer as the main control chip, the system design of Bluetooth remote control system is simple, to be effective in the range (at least 5 meters) can receive and transmit wireless Bluetooth remote control, the object is 4 (LED), using 11.O592MHz crystal, to control the LD3320 voice module and 89C51 microcontroller program in this design, is mainly composed of two parts, one is the receiving part, another part is sent, the two part of the circuit is exactly the same, to choose their own distribution.
