AI Technical Summary

Technical Problem

In the testing of weapon explosion power and damage parameters, the effect parameters are difficult to measure due to the uncertain landing point of the gun bomb, and the existing technology is difficult to adapt to different ranges, resulting in inaccurate measurement or overload measurement.

Method used

Adaptive measurement method of wide range sensitivity is adopted. By dividing the range range into multiple range segments, each range segment is equipped with a sensor of corresponding sensitivity, and using an adaptive amplification limiting circuit and an adder circuit, the output signals of multiple sensors are processed uniformly to achieve adaptive sensitivity.

Benefits of technology

Achieve sensitivity adaptation within different ranges, ensuring that signals can be measured effectively and accurately in each range section, solving the problem of inaccurate measurement or overload in measurement caused by the inability to determine the measured parameter range in advance during on-site testing.

Abstract

The present invention belongs to the field of dynamic testing technology, and relates to a wide-range sensitivity adaptive measurement method and a measuring device. A wide-range sensitivity adaptive measurement method is proposed: a wide range is divided into a plurality of range segments from small to large; each range segment is respectively configured with a sensor of appropriate sensitivity; an amplification and limiting circuit is configured for the sensor of each range segment; the output signals of each adaptive amplification and limiting circuit are input to the adder circuit at the same time; the output signal of the adder is collected by the data acquisition circuit and converted into a digital signal for storage. The present invention solves the problem of inaccurate measurement or measurement overload caused by the inability to predetermine the range of the measured parameter during field testing.
