摘要

摘要: 定向起爆技术在自主攻击型水下航行器上的应用, 需要水下目标触发探测器能够提供目标方位信息; 同时, 为了应对不同性质的水下目标, 需要水下目标触发探测器能够随时更改触发阈值。现有的以机械式惯性开关作为敏感部件的水下目标触发探测器无法感知目标方位、无法更改触发阈值。基于此, 文中采用微机电系统(MEMS)加速度计作为惯性敏感部件, 并与嵌入式微处理器技术结合, 设计了一种基于MEMS加速度计的水下目标触发探测器。分析了输入信号的特性, 规划了输出信号形式, 介绍了水下目标触发探测器的总体技术方案及软、硬件实现途径, 并对原理样机进行了几种典型工况下的功能试验。试验结果表明, 基于MEMS加速度计的水下目标触发探测器技术方案有效、可行, 能够实现感知和输出目标方位信息、在线更改触发阈值的功能。

Abstract: The application of directional detonation technology in autonomous attack undersea vehicle requires an undersea target trigger detector to provide target orientation information. At the same time, in order to cope with different undersea targets, the undersea target trigger detector needs to be able to change the trigger threshold at any time. However, the existing undersea target trigger detector with mechanical inertia switch as the sensitive part cannot perceive the target orientation and change the trigger threshold. This study proposes an undersea target trigger detector based on micro-electromechanical system(MEMS) accelerometer by using MEMS accelerometer as inertial sensor and integrating it with embedded microprocessor. The characteristics of the input signal are analyzes, the form of the output signal is planned, the overall technical scheme of the novel undersea target trigger detector and the way to realize the hardware and software are introduced, and function tests are conducted on the principle prototype under several typical working conditions. Experimental results show that the MEMS accelerometer-based undersea target trigger detector is effective and feasible, and it can realize the functions of sensing and outputting target orientation information and online changing the trigger threshold.
