An Architecture Of Individual Soldier Computer System And The Design Of Wireless Communications Module

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.
