Research On The Application Of Embed System In Technology Of Top Searching North

The technology of high precise searching north is the key technology in the land-based launching system; It has important influence on the shooting precise of weapon, the reacting time of army and the concealment and viability of army. It has important theoretic and practical significance to study the technology of rapid, high and precise searching north for the development of national weapon system.After the technology of IT network, the embedded system is a new developing direction of technology. As the embedded system has the prominent characteristic of tiny body, powerful capability, low consume, high reliability and facing professional application, it has been extensively applied in the national defense, electronic consume, net communication and industrial control. Because of the large developing scope of the embedded-based inertia navigation, there are already a large amount of 8 bit, 16 bit and 32 bit applying in it now. With the development of micro-electronics and military high technology, the 32 bit and 64 bit micro-processor will gradually become a most important part of the automated equipment of national weapon, and will develop more rapidly in recent year.The purpose of this article is to develop a micro-controller applied in the rapid location of land-based weapon, which is a important significance in improving the fighting and existing ability of army. It take the designing principle of the embedded system and practical application of the top searching-north as the core of this article, and do a series of research in theory and practice.The main research of this paper is:Firstly, this essay comprehensively and systemically summarizes the definition and components of embedded system, the application of some field and developing direction of embedded system.Secondly, it systemically analyzes the main principle and structure of the searching-north top, and emphatically explained the principle of searching north and direction of the searching-north top.Thirdly, this essay systemically introduces the minimal system design of ARM micro-processor, and brings forward the hardware designing scheme of the computer controlling system of searching-north instrument and the relevant software realizing procedure.Finally, it puts forward the transplant of embedded operating system and multitask-program compiling, and detailedly explains the transplanting procedure of theμC/OS-II real-time operating system which is based on the hardware platform of embedded controller LPC2292.
