Adaptive Acceleration Based On High G Micro Meter Drill Fuze System

Fuze system is very important part in Earth Penetrating Weapon. With Earth Penetrating Weapon developing quickly recently, it's urgent to advance the fuze system designing. Nowadays, fuze system has been developing at aim of integration, multifunction, real-time and reliability as MEMS technology and Integrated circuit technology progress. The accelerometer used by fuze affects the precision of fuze system directly; the accelerometer signal modulation and the design of advanced fuze algorithm ensure the fuze system could work reliably and in time.After the high-G arrayed Micro-Accelerometer was designed and fabricated successfully, this paper analyzed the characteristic signal of accelerometer in order to supply the theory sustain for the application of sensor. The objective of this study was to contrive a scheme of accelerometer signal modulation and signal process, and to carry out a new fuze algorithm. This paper completed the design by the advanced integrated circuit device and flexible integrated circuit design method which contributed to the real-time and multifunction of fuze system. The paper is organized into the following sections:1. According to the structural characteristic of accelerometer and the process technics, we got the characteristic of impact signal by analyzing the high-G-impact experiment results, and supplied the theory sustainment for improving of accelerometer structure and application.2. After analyzing the penetrating process of Earth Penetrating Weapon, we described a new multifunctional adaptive fuze algorithm in order to improve the performance of fuze system, by combining the"calculating of penetration depth"and"target medium identification"which were the more advanced fuse algorithms.3. In the face of analog channels design, we took use of the IC chip to design the signal modulation module, data acquisition and peripheral circuits.4. Controlling the multi-channels of the data acquisition, digital filtering for the acceleration signal and logic operation were designed and simulated by FPGA, and data acquisition was carried out by multi-channel synchronous sampling and time-sharing...
