基于 ARM+DSP 多功能车内语音终端的设计与实现
摘要
随着通信、网络等技术的不断发展,对车内(机内)通话系统提出
了更高的要求。本文以军用车内通话系统为主要应用背景,实现对现有
车内通话系统的升级和改造,主要涉及系统结构、软件流程、相关接口
及通信协议等内容。
早期模拟车内通话系统已经不能满足数字化建设的需要。现役的数
字式车内通话系统普遍功能单一,不具备数据传输等功能。而且系统组
成单体设备种类多、接口不统一、兼容性差,较难实现通用化设计。
本文提出一种基于 ARM+DSP 架构的多功能车内通话系统。主要由多
个语音终端、一个主控盒以及头戴通信帽等硬件组成,最大可支持车内
16 个乘员之间通话,具有群呼、组呼、选呼、强呼、数据传输等功能,
系统内乘员还可以通过主控盒与车外网络的用户进行通话或通信。
论文共分七章,主要内容包括:(1)车内通话系统的国内外发展现
状和趋势;(2)语音终端系统设计,包括软硬件实现、通信协议等;(3)
语音终端设计中几个关键技术的分析和研究。
本文设计的语音终端话音质量高,扩展功能强大,成本相对低廉,
除适合在军用通信领域外,在商用领域也具有良好的市场前景。

基于 ARM+DSP 多功能车内语音终端的设计与实现[0] ABSTRACT
THE DESIGN AND IMPLEMENTATION OF MULTI-FUNCTIONAL
VOICE TERMINAL INSIDE THE VEHICLE, BASED ON ARM+DSP
ABSTRACT
With the constant development munications technology and
network technology, the telephone system inside the vehicle has been put
forward higher requirements. This paper takes the military vehicle system as
the main background, and points out the realization of upgrade and
transformation to this system, which is mainly related to system architecture,
software process, the relevant interface munication protocol and so
on.
The origin analog telephone system inside the vehicle has no longer met
the needs of digital construction, for which is generally only has a single
function instead of the data transfer function. Also there are many types of the
monomer equipments, non-unified interfaces and patibility, which is
rather difficult to achieve universal design .
This paper presents the multi-functional voice system inside the vehicle
based on ARM+DSP. The system consists of multiple voice terminals; one
main control box and munication caps and it can strongly
support the munication between 16 crews with Relation Call,
Group Call, Selective Call, Force Call, Data Transmission and other functions.
At one time, the crew can also speak work users outside the vehicle
via the main control
