The on-resistance,isolation resistance and the ground insulation resistance of the firing circuit of the multiple rocket launcher are the key parameters to determine the normal firing,delayed firing,misfiring or chamber failure of the rocket launcher.In order to realize the rapid and accurate detection of this parameter,this paper studies the generation mechanism of the insulation resistance and leakage resistance of the transmitting loop,proposes the resistance detection technology based on embedded single-chip microcomputer technology and weak current detection technology,adopts the voltage comparison method,and designs the resistance detection technology,and completes the de-velopment of the detector.The research results of this paper have the advantages of advanced technology and strong applicability,which are not only suitable for the field use of the army,but also for the adjustment inspection of the manufacturer,the inspection of the overhaul factory,the fault detection and repair acceptance during the maintenance process.
