[0018] Now the utility model is further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0019] First, as Figure 1 As shown, a delay control module for a prefabricated fragmentation programmed fuze bullet includes an ignition switch S1, a delay chip U1, a resistor R1, a resistor R2, and a resistor R3. The contact A1 signal is connected in series with the resistor R1 and then connected to the A1 pin of the delay chip U1. The contact A2 signal is connected to the cathode of the diode D2. The anode of the diode D2 is connected in series with the resistor R2 and then connected to the A2 pin of the delay chip U1. The contact B signal is connected in series with the resistor R3 and then connected to the A1 pin of the delay chip U1. The contact A1 signal is connected to the anode of the diode D1, and the cathode of the diode D1 The series capacitor C1 is then connected to the GND pin of the delay chip U1, the cathode of the diode D1 is connected in series with the ignition powder and the transducer element Q1 and the ignition switch S1, and then connected to the GND pin of the delay chip U1, the cathode of the diode D1 is connected in series with the low voltage difference linear regulator LDO, and then connected to the VCC pin of the delay chip U1, the fire signal output pin of the delay chip U1 is connected to the switch conduction control terminal of the ignition switch S1, one end of the capacitor C2 is connected to the VCC pin of the delay chip U1, and the other end of the capacitor C2 is connected to the GND pin of the delay chip U1.
[0020] When the external contact A1 signal and the contact A2 signal are short-circuited, the external detonation box powers on the delay control module, the delay chip U1 of the delay control module starts timing, and the capacitors C1 and C2 start charging; after the contact A1 signal is disconnected from the contact A2 signal, the ignition switch S1 in the delay control module is closed after the preset delay time expires, and the capacitor C1 supplies power to the ignition powder and the transducer element Q1 to make them work, igniting the ammunition inside the warhead, and the ammunition inside the warhead is ignited, causing the warhead to explode as a whole. After the preset delay time expires, the ignition powder and the transducer element Q1 work and then ignite the gunpowder to make the bullet explode. At this time, the bullet is close to the drone, and the fragments produced by the bullet explosion can hit more drones in the swarm combat, so the hit rate is higher, and the manufacturing cost is significantly lower than that of the Ahead bullet.
[0021] Specifically, in an optional implementation manner, Figure 2 As shown, the delay control module with feedback communication also includes a resistor R4 and a switch S2. The contact A1 signal is connected in series with the resistor R4 and the switch S2 and then connected to the GND pin of the delay chip U1. The FB pin of the delay chip U1 is connected to the switch conduction control terminal of the switch S2.

When the bullet is separated from the metal cartridge case 2 , the contact A1 area 102 and the contact A2 area 103 are insulated through the first insulating tape 104 .
[0024] Through the above-mentioned special bullet design, the bullet forms three mutually insulated areas, the contact A1 area 102, the contact A2 area 103 and the contact B area 101 form an insulating relationship, and the contact A1 area 102 and the contact A2 area 103 form an insulating relationship, which is significantly different from the conventional metal bullet. Conventional metal bullets can only output one type of contact information, and the improved bullet of the utility model can output three different types of contact information. The contact B area 101 outputs the contact B signal through the B probe, the contact A1 area 102 outputs the contact A1 signal through the A1 probe, and the contact A2 area 103 outputs the contact A2 signal through the A2 probe. Through different probes, the bullet of the utility model can output the contact A1 signal, the contact A2 signal, and the contact B signal.
[0025] Specifically, in an optional implementation manner, Figure 4 As shown, the projectile is installed in a magazine, and the magazine has a magazine shell 301. A vertical cavity is formed inside the magazine shell 301. An A side contact 302 is provided on the left side of the inner wall of the magazine shell 301, and a B side contact 303 is provided on the right side of the inner wall of the magazine shell 301.
