Design Of The Infrared Laser Shooting Training System

At present, Shooting Training in the forces is still mainly using live ammunition. In this way, training costs a lot of money. It also requires special training venues, and there is potential safety hazard. So, forces have a limited Practical Shooting Training each year, soldiers are unfamiliar with the shooting skills, and the results may be not very good.Domestic researchers have done related research on laser simulated shooting, but their work is mainly used to tactical training. Some researchers have also worked on laser shooting training systems for soldiers, but most of them use photodiodes to receive laser signals, which have a very complex subsequent processing and weak resistivity against disturbance.In this paper, microcontroller STC12C60S2is used as the core, which controls an infrared laser tube to send modulated and encoded signal. An array which is made up of some infrared integrated receivers HS0038B is used to receive and demodulate infrared laser signal, and then the demodulated signal is decoded by remote control decoder PT2272. All decoded data is read into microcontroller serially by parallel input/serial output shift register74LS165, so the interface is very simple. The microcontroller processes the data, and then the shooting result will be displayed on a LCD, which is visible in the strong light, and also be voice broadcasted. The shooting result will also be uploaded to the control center. Each module of the system communicates wirelessly with each other, and the power is supplied by battery. The system can be used indoor, outdoor or in other occasions, so it is very convenient and flexible.
