【摘要】：无线通讯技术的快速发展让手机走进了我们的日常生活,它在满足人们快速、高效、便捷的获取信息服务的同时也带来了一系列的问题。手机可以随身携带,但是可能因为没电,信号弱,甚至在偏远地区没有信号而导致电话漏接。固定电话这几年虽然没有得到较大发展但是由于其正规性、低辐射等优点也有它存在的必要性。本文主要就是设计一个串口电路,把计算机、固定电话、蓝牙耳机连接起来,实现计算机对固定电话拨号和来电显示功能的控制同时也可以使用蓝牙耳机接听固定电话来电,主要优点就是不改变固定电话内部电路结构同时又可以实现对固定电话的控制。本设计的主要任务就是在深入了解固定电话和蓝牙耳机工作原理的基础上,硬件部分使用STC12C5A60S2单片机作为控制核心,使用蓝牙芯片Blue Core5-Multimedia External实现蓝牙耳机与固定电话的连接,使用HT9200A和HT9170D芯片实现计算机控制固定电话拨号和来电显示功能,使用芯片PL2303HX内置的USB收发功能控制器实现计算机和固定电话的连接。软件部分采用模块化程序设计的思想,使用Keil作为编程环境C语言作为编程语言实现对整体电路的控制。
[Abstract]:With the rapid development of wireless communication technology, mobile phone has come into our daily life. It not only meets people's rapid, efficient and convenient access to information services, but also brings a series of problems. However, the lack of electricity, weak signals and even lack of signals in remote areas may lead to telephone leakage. Although fixed-line phones have not developed significantly in recent years, due to their formality. Low radiation and other advantages also have its necessity. This paper is designed to design a serial circuit to connect computers, fixed phones, Bluetooth headsets. At the same time, it can use Bluetooth headset to answer fixed phone calls. The main advantage of this design is not to change the internal circuit structure of the fixed telephone but also to achieve the control of the fixed telephone. The main task of this design is to deeply understand the working principle of the fixed telephone and Bluetooth headset. The hardware part uses STC12C5A60S2 microcontroller as the control core. Blue Core5-Multimedia External is used to realize the connection between Bluetooth headset and fixed telephone. The HT9200A and HT9170D chips are used to realize the functions of computer controlling the dialing and calling display of the fixed telephone. Using the chip PL2303HX built-in USB transceiver function controller to realize the connection between the computer and the fixed telephone. The software part adopts the idea of modular programming. Using Keil as the programming environment C language as the programming language to realize the control of the whole circuit.
