【摘要】：本文研究内容源自科研课题“短波选频与建链技术研究”,为了室内测试与评估此课题中选频与建链系统,此前设计出了基于WinCE的多路短波综合模拟设备软件。经过实际室内测试,基于WinCE的解决方案实时性达不到要求,系统时延导致此设备无法适应高速数据传输,有必要重新设计一套短波综合模拟系统,ARMCortex M3处理器常应用于具有较高实时性要求的系统,基于ARM的短波综合模拟设备在此背景下得以提出。本文对基于ARM的短波综合模拟设备进行了系统性的研究,所取得的主要研究成果为：1.对基于ARM的短波模拟设备方案的可行性进行了分析研究。结合模拟设备的设计需求,给出了基于WinCE的多路设计方案,分析了此方案的应用范围。通过实际测试也验证了基于WinCE方案的局限性,由此引出了基于ARM的裸机开发方案,并就ARM Cortex M3现有的硬件资源详细分析了实现的可能性。2.对基于ARM的短波模拟设备的设计方案进行了研究。结合模拟设备的设计需求与ARM Cortex M3的硬件资源,设计出了基于ARM方案的硬件、软件框架结构。根据模拟设备要实现的功能,设计出了软件结构的各个部分,包括参数设置及初始化部分、收发串口及指令交互部分、信道控制部分。根据硬件、软件模块的设计方案,介绍了实现此方案所用到的关键技术。3.对基于ARM的短波模拟设备的软件实现进行了研究。结合基于ARM方案的设计,最终实现了此方案的核心部分-信道控制部分(包括信道通断控制部分和音频加噪部分)。最后,采用信道通断测试、噪声输出测试和过采样测试等实验手段进行了合理性与逻辑性的测试,实测结果验证了基于ARM方案的信道模拟功能的可行性和有效性。
[Abstract]:The content of this paper comes from the project "the research and construction of shortwave frequency chain technology research", in order to indoor test and evaluation in the subject construction and frequency chain system, previously designed WinCE integrated simulation software based on multi wave equipment. After the actual test, WinCE solution in real time is not up to the requirements based on time delay system the equipment can not adapt to the high speed data transmission, it is necessary to design a set of short wave integrated simulation system, ARMCortex M3 processor is often used in the system with high real-time requirements, comprehensive simulation of shortwave equipment based on ARM is put forward under this background. This paper makes a systematic study on the comprehensive simulation of short wave equipment based on ARM the main research results are as follows: 1. the simulation equipment based on the feasibility of the scheme of ARM short wave are analyzed. Combined with the design requirements of analog devices, to A multi channel design scheme based on WinCE, analyzes the application scope of this scheme. Through the actual test also verified the limitations based on the WinCE scheme, which leads to the bare metal development scheme based on ARM, and ARM Cortex M3 the existing hardware and detailed analysis of the possibility of.2. conducted the research on the design scheme of simulation ARM equipment based on shortwave. Combining with the design requirements and the ARM Cortex M3 simulation equipment hardware resources, design a ARM scheme based on hardware, software framework. According to the simulation equipment to achieve the function, design each part of the software structure, including parameter setting and initialization, send and receive serial and interactive instruction part of channel control. According to the hardware, software design module, introduces the key technology of.3. used to achieve the scheme of simulation equipment ARM software realization based on short wave Were studied. According to the design based on the ARM scheme, finally realizes the core part of this scheme to control the channel part (including channel on-off control and audio noise part). Finally, the channel on-off test, noise test and output over sampling measurement for the rationality and logic of the test the experimental results verify the feasibility of the channel, the ARM scheme simulation function and effectiveness based on.
