[0096] Example 1

[0097] Infrared emitting module

[0098] It employs a 940nm invisible LED or laser diode as the transmitter unit, and uses an aspherical lens and a light shield for beam collimation to reduce scattering. Equipped with a high-speed MOSFET switching circuit, it achieves rapid transmission with a trigger delay of ≤5ms. Data packets are generated by an STM32 microprocessor and encrypted with AES-128, then transmitted using 1kHz infrared carrier modulation. Transmission power and range are graded and controlled according to weapon type (sniper rifle, assault rifle, submachine gun / shotgun, pistol) to ensure differentiated hit experience and range for different weapons.

[0099] Hit detection module

[0100] The sensing nodes are distributed at ≥24 locations across the head, torso, and limbs, employing high-sensitivity photodiodes with a response time ≤10µs. Equipped with signal amplification and filtering circuits, and using a 12-bit ADC to measure signal strength with an accuracy of ±2%. Each node has a unique EEPROM identifier for precise location detection. Hit data is transmitted back to the central computing module via a 2.4GHz or BLE wireless module with a latency ≤30ms.

[0101] Topographic and meteorological data module

[0102] It stores a 3D terrain model and obstacle database with a resolution of 0.5m, which can be updated remotely in real time. The weather sensor includes wind speed, wind direction, temperature and humidity acquisition units to correct for signal attenuation and ballistic deviation, ensuring environmental adaptability for damage calculation.

[0103] Central Calculation and Judgment Module

[0104] The STM32H743 processor performs real-time calculations on multiple parameters, with inputs including the coordinates of the launch point and impact point, weapon parameters, obstacle materials, weather parameters, and player status. The final damage value is calculated using distance attenuation coefficient, caliber coefficient, terrain coefficient, wind speed coefficient, and dynamic coefficient. A signal strength ≥70% and latency ≤50ms are set as the criteria for a valid hit.

[0105] Dynamic damage adjustment module

[0106] The damage coefficient is dynamically adjusted based on the match duration and the player's newbie tag to improve match balance. New players receive damage reduction protection in the early stages, and the coefficient automatically switches to normal once they reach a certain performance level.

[0107] Feedback and Interaction Module

[0108] Immersive feedback is achieved through wearable vibration motors, headphone sound effects, and HUD visual cues. The vibration frequency and amplitude vary depending on the part of the body hit, enhancing the hit experience and sense of presence.

[0109] In a multiplayer competitive match, Player A, wielding an assault rifle (range 400-600 meters), shoots at Player B in a scenario with a wind speed of 2 m / s, a crosswind angle of 30°, and wooden obstacles. The system first collects and encrypts the firing data before sending it. Player B's sensor node receives the signal and reports it. The central computing module accesses the terrain database and meteorological data to calculate a distance attenuation coefficient of 0.85, a wind speed coefficient of 0.99, and a terrain coefficient of 0.7. Combining this with the assault rifle caliber coefficient and dynamic damage coefficient, the final damage value is calculated to be 58.8% of the base damage. The result is fed back to both players' terminals and stored in an anti-tamper database for post-match replay and referee judgment.

S3: Environmental and terrain parameter acquisition, terrain data retrieval: The central computing module retrieves information on obstacle type, location, and thickness from the launch point to the hit point from the terrain database; meteorological parameter acquisition: The meteorological module collects real-time environmental data such as current wind speed, wind direction, temperature, and humidity; parameter integration: The terrain and meteorological data are associated with the firing data and hit data to form a complete calculation input. S4: Ballistics and damage calculation, distance attenuation coefficient calculation: distance attenuation coefficient = 1 - (actual distance / maximum range) × 0.5, caliber kinetic energy coefficient call: matched to preset value according to caliber, terrain penetration coefficient determination: assigned according to obstacle type, wind speed correction coefficient calculation: wind speed correction coefficient = 1 - (wind speed × 0.02 × sin(angle between wind direction and ballistics)), dynamic damage coefficient call: obtained from dynamic damage adjustment module according to game time and player novice tag, final damage value calculation: final damage = base damage × distance attenuation coefficient × caliber coefficient × terrain coefficient × wind speed coefficient × dynamic coefficient; S5: Hit determination and result generation, validity verification: confirm signal strength, delay, and data packet integrity, result generation: if determined to be a valid hit, a hit record is generated, data storage: the hit record is written to the blockchain or tamper-proof database to ensure the fairness and traceability of the competition; S6: Feedback and Status Update. Attacker Feedback: Hit notification sound is played via gun vibration and radio headset. Target Feedback: Vibration feedback is triggered by the sensor clothing, the headset plays a hit sound effect, and the remaining health is displayed on the HUD or terminal. Status Update: The central system updates the health and battle data of both players and synchronizes them to the server and referee terminal. S7: Data storage and analysis, real-time storage: stores all firing, hit, and damage determination records to the server database, post-match analysis: the system can generate battle replay reports, including data such as hit rate, average range, and damage distribution, for match replay and strategy analysis.
