题 目：无线数字语音收发器 无线数字语音收发器 摘 要 无线语音传输相对于有线传输，可以有效的降低成本、提高效率，并且不受地理环境和地面状况的影响，而且可以方便的把新设备加入系统中。系统无线通路发生故障时可以直接更换无线数传模块，立刻恢复系统的数据传输通路，维修方便。 本文着重研究无线数字语音收发板的设计，具体分析设计了无线数据收发模块。本文所设计的无线数据收发模块主要由Silabs公司生产的一种微控制器芯片C8051F330和TI公司生产的一种无线芯片CC1020组成。这部分的设计包括：原理图设计，PCB设计和C8051F330的应用程序设计。本文先从整体上介绍了该课题的设计思想和层次结构，然后详细介绍了无线数据收发模块的设计过程，并给出了程序流程图。本设计实现了通过无线数据收发模块把语音信号的数据传送给主机处的单片机，并且可以通过单片机来控制系统状态的功能。 无线语音收发器具有成本低廉，扩展性好，受地理限制少，安装施工简易等特点，在许多领域都有广泛应用。 关键词： 无线语音收发器；CC1020；C8051F330 Wireless voice transceiver Abstract Wireless voice transmission as opposed to cable transmission, it can effectively reduce costs and improve efficiency, it also doesn’t affected by geographical environment and ground conditions, meanwhile it would also facilitate the accession of the new equipment system. Wireless access system failure can be directly replaced wireless module, immediately to resume the data transfer system access to facilitate maintenance.  This article focuses on wireless digital audio transceiver board design, the design of a concrete analysis of wireless data transceiver modules. This article is designed to send and receive wireless data module produced by Silabs a C8051F330 microcontroller chip manufactured by TI and a CC1020 radio chip components. This part of the design include: schematic design, PCB design and design C8051F330 applications. This article first describes the overall design of the subject and the hierarchical structure, and then details the design process of wireless data transceiver modules, and gives the program flow chart. The design achieved through the wireless data transceiver modules of the data to voice signals transmitted to the Office of the single-chip host and can be single-chip microcomputer to control the functions of the system state.  Wireless voice transceiver has a low-cost, scalable, and less subject to geographical restrictions; it is easy to install features such as construction, so it is widely used in many fields.
