摘要
针对弹丸飞行姿态测试中高速摄影机的触发需求,以微控制器和数传电台为核心部件,设计了无线遥控触发系统.系统具有可灵活组合,可扩展性好,可靠性高,能够全天侯遥控操作等优点.验证试验表明,系统可以实现12 km以内的遥控触发,触发延时约27 m s.可以通过提高发射功率和天线高度,延伸遥控距离.
With a MCU and a wireless data transceiver as key components, a wireless remote-control trigger system was designed for high-speed photography of the flight attitude of projectiles. The designed system has the advantages of flexibility, expandability, credibility and all-weather remote service, and competent for high-speed photography of the flight attitude of projectiles. With very strong practicability, it can be widely used in the related fields.
