【摘要】 目前,信息战被认为是未来战争的主要作战样式。在信息战下战场必将是数字化的战场。因此,各国都在研究单兵作战系统,以提高单兵在未来数字化战场上的作战力和生存力。本毕业设计主要基于Cirrus Logic公司的EP7212微处理器进行单兵计算机系统的研究与结构开发,完成了单兵计算机系统的基本硬件平台的构建,主要实现了语音通信和定位功能。具体来说,以微处理器EP7212为核心,外围扩展了闪存和CF卡芯片SST48CF024,USB芯片PDIUSBD12,音频处理芯片CS43L42,以及夏普LM057QC1T03 1/4VGA。彩色非触屏LCD显示模块,构成了系统的硬件基础;另外,利用ZigBee芯片CC2431实现了语音通信模块和定位模块的设计。总体上,实现了单兵计算机系统在实战应用中所需的功能要求。本毕业设计的主要创新点:一、整个系统的设计采用低功耗原则,所选部件都是低功耗产品,极大的提高了系统的实战应用能力;二、将最新的ZigBee无线技术应用于单兵系统,实现了单兵小分队队员间无线传输与语音通信,性价比高,实用性好;三、结合我国具体军队装备投入状况,利用CC2431与EP7212结合构成定位模块,实现相对定位功能,整个模块功耗低、体积小、重量轻、成本低、精度高、实用性好。本毕业设计的硬件实现具有良好的通用性,不仅可以应用于单兵计算机系统,在民用通信、工矿定位、抢险救灾、环境监控等领域都有广泛的应用。更多还原

【Abstract】 Nowadays, information warfare is considered as the chief fighting form of future warfare. Under the information warfare, the battlefield would became digital. Therefore, in order to enhance the combat capabilities and survivability of individual solider on the future digital battlefield, each country is doing some research on individual soldier fighting system.The project mainly focuses on the research and development of the individual soldier computer system, which bases on the Cirrus Logic microprocessor EP7212. The project accomplishes the establishment of the hardware platform, and realizes the functions of localization and voice communication.In detail, the project utilizes the EP7212 as the core of the hardware system, peripherally adds FLASH, CF card chip SST48CF024, USB clip PDIUSBD12, audio processing chip CS43L42, SHARP’S LCD chip LM057QC1T03, which altogether compose the base of hardware. Besides, the project realizes the design of localization module and voice communication module, which uses of the ZigBee chip CC2431. In all, the contents above altogether meet the acquirements of application in actual combat.The main innovative points of the project:Firstly, the design of the whole system is on the principle of low power, all chooses are the low power partses, which greatly improves the ability of application in actual combat.Secondly, ZigBee, the latest wireless technique is applied in individual soldier system, which realizes the design of wireless transmission and voice communication, and the system is high performance-price ratio and good practicality.Thirdly, the project combines with our country’s condition of the military equipments investment at present, realizes the design of localization module by use of CC2431 and EP7212, and the module is low power, small volume, light weight, low cost and high reliability. The system has a good generality and expansibility, and can be widely used not only in individual soldier computer system, but also in civil field such as communication, emergency and disaster releasing, environmental monitoring.更多还原
