Missile-borne recorder with three-way impact sensor chip

Abstract

The invention relates to the technical field of high impact signal detection, and especially relates to a missile-borne recorder with a three-way impact sensor chip. The missile-borne recorder comprises a main control module, a power supply module, a signal processing circuit, a signal conditioning circuit and a storage module, the missile-borne recorder further comprises a three-way impact sensor, the three-way impact sensor comprises a wafer substrate and three sensitive elements for detecting impact acceleration, each sensitive element comprises a plurality of long-strip-shaped silicon beams and two parallel mass blocks located on the same plane, the wafer substrate is provided with a plurality of square grooves used for accommodating the mass blocks, all the silicon beams in abut fit with the same mass are provided with strain resistors, and the strain resistors are electrically connected with pins. The size of the missile-borne recorder is greatly locked, the problem that the collection mode is single is solved, and the problem that the test accuracy is not high is solved. The possibility of detection failure can be reduced.

Description

technical field [0001] The invention relates to the technical field of high impact signal detection, in particular to a bomb-borne recorder with a three-way impact sensor chip. Background technique [0002] With the rapid development of modern weapon science and technology, the missile field flight test has become the main means to obtain the real performance of the missile penetration process. An important basis, the ballistic recorder is used for the real-time conditioning, collection, processing and recording of various test signals on the projectile before and after launch, flight and landing penetration of the whole or part of the process, and it will be completed at the end of the entire test process of the projectile. A test instrument or equipment that uses corresponding technical means to recover the data stored in the data recording device. [0003] The ballistic recorders on the market have the disadvantages of large size, single acquisition mode, weak impact res...

AI Technical Summary

Problems solved by technology

[0003] The ballistic recorders on the market have the disadvantages of large size, single acquisition mode, weak impact resistance and low reliability. The shock sensors equipped in traditional ballistic recorders are all single-axis shock sensors, and then mounted on the PCB circuit board according to X, Y, Z are arranged in three directions to form a three-axis shock sensor system

The size of this product is too large and the test accuracy is not high
