This group studies and designs the shooting training auxiliary system based on the 95 automatic rifle. According to the design requirements, the overall system structure block diagram is shown in the figure. The shooting training auxiliary system includes two subsystems: simulation training equipment and upper computer system. What I have studied and produced is the hardware system of simulation training equipment. The system consists of five parts: data acquisition part, communication transmission part, information display part, data analysis and processing part, voice feedback part. there are six modules in total, which are human heart rate module, ambient temperature and humidity module, gyro sensor module, wireless communication module, speech synthesis module and oled display module. among them, gyro sensor module, ambient temperature and humidity module, human heart rate module and speech synthesis module realize various functions under the control of core control panel, and the measurement data calculated by each module through the core control panel is transmitted to the upper computer software database in real time through the wireless communication module, and the upper computer software drives the speech synthesis module through the wireless communication module, and feeds back to the trainers and group trainers in the form of speech, providing them with first-hand training data, so that the shooters can adjust the gun action in time and improve the shooting posture in the subsequent shooting training process, so as to gradually improve the results of shooting training. oled display module displays visual graphic information.
