摘要现代战争对武器的综合性能要求越来越高，如何提高打击目标和降低弹药成本成为了武器工程技术人员迫切需要解决的问题。目前在解决这一问题时采用较多的方案就是对弹道修正弹药方面研究和应用。而弹道修正弹就是在原有“笨”弹的基础上添加弹道修正模块。弹道修正装定器是弹道修正模块能够完成既定目标的前提。63536

论文首先对于目前国内外的弹道修正引信做了调研，分析了相关装定技术的优缺点，最终提出以AVR单片机为核心的信息装定器设计方案。采用AVR单片机将来自于GPS接收机的GPS星历和来自激光测距传感器SKD-30的距离信息装定给弹载计算机，为其进行弹道解算而控制弹载阻尼系统完成弹道修正任务提供原始数据。

其次根据系统的总体设计方案，给出了相关的硬件和软件设计。采用ATMega128为核心设计了系统的硬件系统，包括TFT显示器、矩阵键盘、实时时钟等多个模块。并采用模块化编程思想对其软件进行了设计。

最后通过对TFT的显示、传感器的控制与数据传输和UART串口进行了相关实验，结果表明该系统的方案是可行的，能够较好地完成我们预期的一维弹道修正装定任务，可以用于实际中。

Title A design scheme of one-dimensional trajectory correction information setting device

Abstract Modern warfare proposes much higher performance demand of weapons.It is becoming more and more important in the research field of weapons that how to improve the performance of conventional weapons on the premise of saving costs.A common solution on this problem is doing research and applying trajectory correction munitions at present,which added a trajectory correction module on the basis of the original "dumb" bombs.And a device which was used to set some information to the CPU on the munition is the promise of trajectory correction。

First the advantages and disadvantages of trajectory correction fuse both in China and aboard was analyzed and compared.On the basis of that,design of the whole system was proposed:using AVR micro controller to set GPS data and the target distance to the CPU on the munition,which is used to do ballistic calculation work,the in order to achieve the goal of trajectory correction. 

Second based on whole system design, the planning for the controller hardware and software was made.Using ATMega128 as the core control chip,hardware part containing TFT display, matrix keyboard, real-time clock and other modules.Based on the modular programming ideas,the software of the system was designed.

Finally,the results of experiments related TFT display,laser sensor,data transmission and UART serial port showed that the system is feasible,can complete the task of setting one-dimensional trajectory correction information.It can be used in practice.
