Initiating explosive device resistance measuring circuit and measuring method

Abstract

The invention provides an initiating explosive device resistance measuring circuit and a measuring method. The measuring circuit comprises a plurality of channel switching modules, a voltage-controlled constant current source module, a microprocessor and a signal processing module, each channel switching module is used for switching the connection direction of the corresponding initiating explosive device resistor to the voltage-controlled constant current source module according to a control signal output by the microprocessor; enabling a signal processing module to collect a first voltage difference when each initiating explosive device resistor is positively connected to the voltage-controlled constant current source module and a second voltage difference when each initiating explosive device resistor is reversely connected to the voltage-controlled constant current source module; the microprocessor is used for measuring the target resistance value of each initiating explosive device resistor according to the first voltage difference and the second voltage difference of each initiating explosive device resistor; the initiating explosive device resistance measuring circuit solves the problem that in the prior art, an initiating explosive device resistance measuring circuit is low in measuring precision, the resistance value of an initiating explosive device is measured forwards and reversely, therefore, the potential influence is reduced, and the measuring precision of the initiating explosive device resistance is improved.

AI Technical Summary

Benefits of technology

This patented technology allows for accurate measurements with two different types of resistors: one being used during normal operation while another type called an antiarrhythmic or antimicrobial (A) component. By connecting these components together at opposite ends, it becomes possible to connect them into channels without affecting their functioning properly. These connections allow signals from both parts of the device to be processed simultaneously instead of separately. Additionally, this design enables fast detection of changes caused by certain substances like bacteria or other harmful organisms.

Problems solved by technology

This technical problem addressed in this patented text relates to measuring the resistivity (R) when testing pyro-mistors used in vehicles during flight operations. Current methods involve applying multiple currents at different times while trying to maintain accurate results due to the influence from other components such as magnetic fields that may affect its measurements.
