When shooting at a shooting range, in order to obtain the correct regions and directions on the target board, that is, to provide the position of the specific impact point when the shooter shoots, a control device is required to capture the bullet hit signal generated by the conductive target board in real time, perform data analysis to generate shooting scores and send them to the target reporting end, so as to provide real-time feedback on the shooting situation.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1, A control device based on a conductive target plate, comprising a lithium battery power supply, an LDO voltage stabilization module, a resistor-capacitor network, a single-chip microcomputer, a wireless module, a host computer display terminal, and a wireless transmission module. The lithium battery power supply is connected to the LDO voltage stabilization module. The conductive target plate is connected to the input end of the resistor-capacitor network. The output end of the resistor-capacitor network is connected to the ADC channel of the single-chip microcomputer. The sending end of the wireless transmission module is connected to the serial port output end of the single-chip microcomputer. The receiving end of the wireless transmission module is connected to the host computer display terminal. The lithium battery power supply, the LDO voltage stabilization module, the resistor-capacitor network, and the single-chip microcomputer are all installed in a housing. The housing and the sending end of the wireless module are fixed under the conductive target plate. The lithium battery power supply uses two 18650-2550mAh lithium batteries. The LDO uses an ME6118 voltage stabilization chip. The resistor-capacitor network uses a resistor-capacitor parallel network. The wireless module uses a wireless 433 transmission module. It also includes a host computer display. The host computer is communicatively connected to the wireless module.

[0020] Specifically, through the lithium battery power supply, the system can operate for a long time without an external power supply. The LDO voltage stabilization module ensures that the system can still obtain a stable voltage supply when the battery power changes, thus ensuring the stability and reliability of the system. The resistor-capacitor network effectively filters the noise signals on the conductive target plate and improves the signal quality. The single-chip microcomputer collects the signals processed by the resistor-capacitor network through the ADC channel and can more accurately analyze the position and force information of the bullet hit. Through the wireless module, the device can transmit the shooting data to the host computer display terminal in real time, realizing wireless data transmission. This not only improves the flexibility of the system but also enables the shooter to view the shooting results anytime and anywhere, so as to adjust the shooting posture in time. The 18650 lithium battery has the characteristics of high energy density and long life, which can ensure the stable performance of the device during long-term use. The capacity of 2550mAh ensures that the device can continue to work for a long time after a single charge. The ME6118 voltage stabilization chip has the characteristics of high precision and low noise, can provide a stable output voltage, and effectively suppresses the influence of power supply noise on the system performance. The resistor-capacitor parallel network can effectively filter out high-frequency noise and interference signals and improve the signal quality, which is crucial for ensuring the single-chip microcomputer to accurately analyze the bullet hit signal.

[0021] Please refer to Figure 1 , The single-chip microcomputer uses two STC8H8K64U type single-chip microcomputers, and the two STC8H8K64U type single-chip microcomputers are connected through serial port communication.

[0022] Specifically, the STC8H8K64U single-chip microcomputer features high performance and low power consumption, capable of meeting the device's requirements for data processing and real-time response. At the same time, using two single-chip microcomputers for parallel processing can further improve the system's processing speed and performance. The wireless 433 transmission module has a relatively long transmission distance and stable transmission performance, ensuring that shooting data is not lost or distorted during transmission, which is crucial for achieving real-time feedback of shooting data. The shooting range shooting control device uses two STC8H8K64U single-chip microcomputers. The first single-chip microcomputer is used to collect and analyze the hit signals of the 6 ring targets on the conductive target board, and the second single-chip microcomputer is used to collect and analyze the hit signals of the 12 direction positions on the conductive target board. The first single-chip microcomputer sends the processed ring target data to the second single-chip microcomputer through the serial port. The second single-chip microcomputer sends the processed direction position data and the received ring target data to the wireless module for transmission through the serial port, and finally, the real-time feedback of the shooting situation, including the ring number and direction position, is completed through the upper computer display terminal.

[0023] Please refer to Figure 2 , the conductive target board is composed of conductive cloth providing 6 circumferential regions and 12 direction positions. The 18 ADC channels of the single-chip microcomputer collect the bullet hit signals of 6 circumferential directions and 12 direction positions in the conductive target board through a resistor-capacitor network. At the same time, the single-chip microcomputer system analyzes the data of the 18-channel signal hit situation and sends the position of the specific impact point parsed out to the upper computer through the wireless transmission module. The wireless module uses a wireless 433 transmission module, and the single-chip microcomputer is connected to the sending end of the wireless module through a serial port interface, and the upper computer is connected to the receiving end of the wireless module.

[0024] Working principle: When in use, when a shooter shoots at the conductive target board, the hit of the bullet will cause an instantaneous change in the electrical signal of the conductive layer on the conductive target board. These electrical signal changes are filtered and amplified through a resistor-capacitor network to eliminate noise and interference and improve the signal quality. The signal processed by the resistor-capacitor network is transmitted to the ADC channel of the single-chip microcomputer. The single-chip microcomputer parses out the position and force information of the bullet hit. These information are shared and collaboratively processed through serial communication between single-chip microcomputers. Then, the processed data is transmitted to the sending end of the wireless module. On the upper computer display terminal, the shooter can clearly see the shooting results, including the target ring number and specific azimuth information.
