【摘要】：便携超短波通信平台在当今的一些特殊通信场景中,起着日益重要的作用,特别是在战地、救灾现场及通信抢修现场等场景中,其重要性不言而喻。随着与嵌入式技术相结合,以及用户多元化需求的推动,便携超短波通信平台已经由传统的单一语音通信功能,朝着语音、短信、文件传输等多业务并行的方向发展。功能的多样化,建立在软硬件复杂化的基础上。在便携超短波通信平台上,嵌入式软件起着至关重要的作用,它承担着业务数据在底层数据处理硬件和上层软件之间的双向流通。该数据通道能否高效、可靠、实时的完成业务数据的在上下层之间的流通,决定了便携超短波通信平台多媒体业务通信的质量好坏。基于上述开发要求,本项嵌入式软件分为两个部分,硬件抽象层和硬件驱动层。硬件抽象层负责将业务数据从数据处理芯片接口中传送到Android应用层软件中,并负责一部分业务的处理;硬件驱动层负责配置ARM芯片与数据处理芯片之间的数据接口,保证芯片间数据交互正常,同时负责数据处理芯片的控制管理等功能。两个部分有机的结合,实现了一条高效稳定的上下层双向数据通路。本文的主要工作内容如下:第一,详细分析了便携通信平台嵌入式部分软件的需求。明确了其实现数据通的任务,并将其分为硬件抽象层和驱动层两个部分,并对各部分需完成的功能做出了细致分析,为接下来的设计实现做好准备。第二,设计并实现了硬件抽象层和硬件驱动层两部分软件。依据软件开发由总到分的思想,先从总体出发,分别设计了两部分软件的主体架构;然后到细节部分,将各功能独立在单元,以模块化的开发思路,每个功能模块完成一个功能,各模块相互合作,实现通信平台统一的业务数据通路。最后,验证了在便携超短波通信平台上,通过嵌入式软件实现的上下层双向数据通路的业务处理能力。分别对硬件抽象层的各功能模块、驱动层配置的接口,以及整个通信平台进行了测试,并给出了测试结果。
[Abstract]:The portable ultrashort wave communication platform plays an increasingly important role in some special communication scenarios, especially in the battlefield, disaster relief scene and communication repair scene, the importance of which is self-evident. With the combination of embedded technology and user diversity, the portable ultrashort communication platform has been developed from the traditional single voice communication function to multi-service parallel direction, such as voice, short message, file transmission and so on. The diversification of functions is based on the complexity of hardware and software. Embedded software plays an important role in the portable ultrashort wave communication platform. It is responsible for the two-way circulation of service data between the underlying data processing hardware and the upper software. Whether the data channel can efficiently, reliably and realtime complete the circulation of service data between the upper and lower layers determines the quality of multimedia service communication of portable ultrashort wave communication platform. Based on the above development requirements, the embedded software is divided into two parts, the hardware abstraction layer and the hardware driver layer. The hardware abstraction layer is responsible for transferring the service data from the data processing chip interface to the Android application layer software, and is responsible for the processing of part of the business, and the hardware driver layer is responsible for configuring the data interface between the ARM chip and the data processing chip. Ensure the normal data exchange between chips, and responsible for the control and management of the data processing chip and other functions. The two parts are combined to realize an efficient and stable two-way data path between upper and lower layers. The main work of this paper is as follows: first, the requirements of embedded software of portable communication platform are analyzed in detail. The task of realizing data communication is clarified, and it is divided into two parts: the hardware abstraction layer and the driver layer. The functions to be completed in each part are analyzed in detail to prepare for the following design and implementation. Secondly, the hardware abstraction layer and the hardware driver layer are designed and implemented. According to the idea of software development from total to division, this paper first designs the main structure of the two parts of software from the overall perspective, and then to the detail part, the functions are independent in the unit to develop the idea of modularization. Each functional module completes a function, and the modules cooperate with each other to realize the unified service data path of the communication platform. Finally, the service processing capability of the upper and lower layer bidirectional data path realized by embedded software on the portable ultrashort wave communication platform is verified. The functional modules of the hardware abstraction layer, the interface of the driver layer and the whole communication platform are tested, and the test results are given.
