5) the target sensing unit acquires information of a target and transmits the information to the fuze control system processor, when the target sensing unit detects the target and locks the target, the fuze control system processor sends a third voltage signal, the third voltage signal is applied to the driving layer executing mechanism through a pair of driving mechanism electrodes, enough electric potential difference is generated between two semi-annular metals of the driving layer executing mechanism, so that tips of the two semi-annular metals are fused under the electric potential difference, the two semi-annular metals are disconnected, the driving layer executing mechanism is switched off by conduction and turning, the short circuit of the electric detonator is relieved, the electric detonator is connected to a series circuit, the three-level fuse relief is completed, at the moment, the solid fuse of the micro attack load ammunition is completely relieved, and the micro attack load ammunition enters an attack state;
6) when the micro attack load ammunition impacts a target, the micro attack load ammunition feels overload, the overload enables the impact switch to be closed, so that the impact switch, the first control layer executing mechanism, the electric detonator, the second control layer executing mechanism and the initiation capacitor which are connected in series form a closed loop, the initiation capacitor releases voltage to initiate the electric detonator, the electric detonator rings a battle part, and the micro attack load ammunition explodes.
