And the display module is used for displaying the number of the bullets and the number of the bullet shells flying out of the firearm. And the power supply module is used for providing working electric energy for each module.
As shown in fig. 1, 4 and 5, the bullet status monitoring module includes a bullet monitoring circuit, a cartridge case monitoring circuit, a voltage comparator U2B and a voltage comparator U2A.
The bullet monitoring circuit comprises a photoelectric sensor U3, a resistor R6 and a resistor R7, wherein the photoelectric sensor U3 is arranged at a bullet throwing port of the firearm main body; the anode A of an infrared emission tube of the photoelectric sensor U3 is connected with a power supply end through a resistor R6, and the cathode K of the infrared emission tube is grounded; the positive electrode C of an infrared receiving tube of the photoelectric sensor U3 is connected with a Pin Pin3 of a voltage comparator U2B and is connected with a power supply end through a resistor R7, and the negative electrode E of the infrared receiving tube is grounded.
The cartridge case monitoring circuit comprises a photoelectric sensor U6, a resistor R10 and a resistor R11, wherein the photoelectric sensor U6 is arranged at a cartridge outlet of the firearm main body; the anode A of an infrared emission tube of the photoelectric sensor U6 is connected with a power supply end through a resistor R10, and the cathode K of the infrared emission tube is grounded; the positive electrode C of an infrared receiving tube of the photoelectric sensor U6 is connected with a Pin Pin5 of a voltage comparator U2A and is connected with a power supply end through a resistor R11, and the negative electrode E of the infrared receiving tube is grounded. In the present embodiment, the model numbers of the photoelectric sensor U3 and the photoelectric sensor U6 are ST 188. ST188 is a photoelectric sensor module composed of an infrared photodiode and a photoelectric transistor, the module has 4 external pins, namely an infrared transmitting tube anode A, an infrared transmitting tube cathode K, an infrared receiving tube anode C, an infrared receiving tube cathode E, a working power supply DC5V of the transmitting tube and the receiving tube, and the effective monitoring distance is 4-13 mm.

The pins P3.2 and P3.3 output high level signals to inform the main control chip whether the warhead and the cartridge case fly out. In the present embodiment, the voltage comparator U2B and the voltage comparator U2A are LM 393.
When the bullet monitoring works, an emitting electrode of the photoelectric sensor U3 can automatically emit infrared rays, if no bullet is emitted from a gun muzzle, the emitting tube can receive the infrared rays to enable C, E of the receiving tube to be conducted, at the moment, the input voltage of a Pin2 Pin of the LM393 is 0V, the voltage of a Pin3 Pin is 2.5V (when the point location device is in the middle position), and as the Pin3 Pin is low in voltage, the voltage of a Pin2 Pin is high, the Pin1 Pin of the comparator can output 0V voltage, and the P3.2 Pin of the singlechip can output low level. If a bullet is shot from the muzzle, the transmitting tube receives infrared rays to disconnect C, E of the receiving tube, the input voltage of Pin2 Pin of LM393 is 5V, the voltage of Pin3 Pin is 2.5V, the Pin1 Pin of the comparator outputs 5V voltage due to the high voltage of Pin3 Pin and the high voltage of Pin2 Pin, and the P3.2 Pin of the main control chip outputs 5V voltage. Therefore, whether the bullet flies out of the muzzle can be judged by judging whether the P3.2 pin outputs a high-level signal.
The operating principle of the shell case monitoring circuit is similar to that of the bullet head monitoring circuit, and whether the shell case flies out from a bullet throwing opening or not can be judged by judging whether the P3.3 pin has high-level voltage output or not.

When the key circuit works, the main control chip reads the input states of the P3.4-P3.6 pins at regular time, and the voltage of which pin is 0V indicates that an operator presses a corresponding key. For example, pin P3.6 goes to 0V, indicating that the operator has pulled the trigger.
As shown in fig. 4 and 7, the main control module includes a main control chip, a reset circuit and a crystal oscillator circuit. The reset circuit comprises a key S1, a capacitor C1 and a resistor R1; after the key S1 is connected in parallel with the capacitor C1, one end of the key S1 is connected with the 5V direct-current voltage end, and the other end of the key S1 is connected with the RST pin of the main control chip and is grounded through the resistor R1.

In the reset circuit, the key S1 is used for receiving a reset command, when both ends of the key S1 are connected, the RST pin is connected with 5V, and when the connection time lasts more than 10us, the main control chip automatically enters a reset state, and the reset operation is finished after the key S1 is lifted. The capacitor C1 and the resistor R1 realize the power-on reset function, the function of the capacitor C1 in the circuit is similar to that of the key S1, when the voltage at two ends of the capacitor C1 is 0-2.7V, the key S1 is in a switch-on state, and when the voltage at two ends of the capacitor C1 is higher than 2.7V, the key S1 is in a lift-off state. The values of the capacitor C1 and the resistor R1 determine the reset time, usually. The capacitance of the capacitor C1 is 10uf, and the resistance of the resistor R1 is 10K.
In the crystal oscillator circuit, the crystal oscillator Y1 is used for outputting an oscillation signal, and the output oscillation signal is subjected to frequency division processing by a trigger in the main control chip, so that the working clock of each part of the main control chip can be obtained. The load capacitor C2/C3 plays a role in stabilizing and fine-tuning the output frequency of the crystal oscillator in the circuit. In general, the crystal oscillator Y1 is selected to be 11.0592M, and the load capacitance is selected to be 20-30 pf.

In the alarm circuit, if fault prompt information needs to be output, the main control chip only needs to control the P3.7 pin to output low level, and then the power supply and the 5V switch-on of the buzzer B1 can be controlled, so that the buzzer B1 enters a working state, and the fault information of the gun is output. If the fault prompt information is required to be forbidden to be output, the main control chip only needs to control the P3.7 pin to output high level, and then the power supply of the buzzer B1 and the 5V are controlled to be disconnected, so that the buzzer B1 stops working, and the fault prompt information is not output.
As shown in fig. 4 and 9, the indicating module includes a single-shot monitoring indicating lamp D1, a continuous-shot monitoring indicating lamp D2, a resistor R2 and a resistor R3; after the single-shot monitoring indicator lamp D1 is connected with the resistor R2 in series, one end of the single-shot monitoring indicator lamp is connected with 5V direct-current voltage, and the other end of the single-shot monitoring indicator lamp is connected with a P1.6 pin of the main control module; after the continuous emission monitoring indicator lamp D2 is connected in series with the resistor R3, one end of the continuous emission monitoring indicator lamp is connected with 5V direct-current voltage, and the other end of the continuous emission monitoring indicator lamp is connected with a P1.7 pin of the main control module. In the indicating circuit, if single-shot indicating information needs to be output, the main control chip only needs to control the P1.6 pin to output low level, and then the single-shot monitoring indicating lamp D1 can be controlled to be lightened, and the single-shot monitoring indicating information is output. If the continuous transmission indicating information needs to be output, the main control chip only needs to control the P1.7 pin to output low level, and then the continuous transmission monitoring indicating lamp D2 can be controlled to be lightened to output the continuous transmission monitoring prompting information.
