Point Of Impact Automatic Detection System Is Developed

The measure of impact location has very important significance in weapon testing and training.Basing on shock wave principle,this thesis designs a new long-distance measuring system of impact location.Analysing the propagation characteristic of bullet's shock wave and discussing some designing schemes of impact location based on shock wave,this thesis chooses the best method to design the system.This thesis analyses the embattle method of the sensors array, discusses the calculation mathematic model of impact location,and studys the calculation means of impact location.This thesis brings forward system's specific frame and give out measuring system's constitution block diagram.Basing on the analysis of sensors' performance,the system chooses the right sensors and designs the front-end circuit to pretreat the signal.By means of the combination of CPLD and microcomputer,the system realizes numeralization and integration,and cuts off the cost.Using wireless transmission to replace of traditional cable transmission,the system becomes flexibility and convenient.In the terminal signal processing,the system's computer adopts special calculation softwave to resolve the coordinate of impact location.Through ball firing test and(?)debugging,the result shows that the system is credible with high accuracy.
