Abstract：The aim of this study is to develop a remote wireless trigger system for high-speed cameras based on microcon-troller technology,in order to meet the demand for unattended triggering in high-speed photography.This system ensures reliable capture of the motion state of fast-moving objects.The system realizes the remote triggering of the high-speed camera through the combination of microcontroller and wireless communication module.The system has the control mode of"one master,one slave"or"one master,multiple slaves",which can be flexibly selected according to the actual needs.After multiple experimental tests,the trigger signal of the high-speed camera is sent from the host transmitter to the output trigger signal of the slave,the delay is about 50 ms,and the farthest communication distance is 15 km.The system has the advantages of high reliability,strong anti-interfer-ence ability and easy operation,which provides a safe and reliable trigger source for high-speed camera.
