Title  The Design of Setting Primer Detector

Abstract 

Setting primer technology makes use of the time interval between the needle touching the primer and the projectile launched to achieve the information setting.This technology can overcome the insufficiency of the existing setting technology,and also implement new high explosive anti-tank cartridge reliable setting before launched.Determined in this paper, the setting primer system working principle is analyzed, improvement scheme of setting primer was introduced in detail, and the scheme is verified by the experiments.Through the analysis of experimental data primer detector design scheme is established.According to the design requirements of detecting performance for setting prime and to ensure the security of the testing process, the dual over-current protection circuit which based on software and hardware combined with is designed.And the whole detector circuit is designed based on this.Also the working principle of the circuit module are analyzed in detail.The experiment’s results verify the accuracy of detection principle at last. The conclusion in this paper has reference meaning to setting primer detector’s engineering design.
