Design And Realization Of The Automatic Target-scoring System Based On Light Screen

The live-fire training which is hold in troops and public security, that can display impact area and statistics shooting scores accurately, is an important thing to correct the method of aiming, cut down the time of shoot training, reduce training cost, and improve the result of shoot training. At present, the method of fix targets and indicate shots is by artificial in the traditional training, whose disadvantages are lack of accuracy and real-time performance and also pose a safety hazard. The traditional way can’t record, statistics and analysis scores automatically, which has a low efficient, also influence the effect of shoot training and assessment.In this paper, a method of automatic target-scoring in live-f ire training based on laser screen to test impact was researched. The method by using the way of prevent laser light from receiving to detect the impact location information and displaying in display side. The method can realize positioning rapidly of the live-fire impact area and broadcasting accurate and efficient to judge. With the advantages of high resolution, statistical analysis results in a timely manner, material consumption, low maintenance costs of late, to overcome the defects of the artificial way of indication of shots for force, it has an important practical significance to the modernization of public security under the condition of military training, especially to the live-fire training and assessment.The paper adopts the technology of laser, automatic control, wireless communication, etc, has realized automatic detection of impact area and display in live-fire training. The paper analyzes the technical feasibility and practicability of this automatic indication of shots, and presents a design framework of the system and the subsystem of form a complete set, include: Target face subsystem, main control system, display subsystem, material management subsystem. Main control system control the other subsystems as well as coordinate setting of impact by using MUC whose class is ARM7; Target face subsystem by the laser beam, laser photoelectric receiving tube and the composition of latch circuit, collect the bullet trajectory parameters; Display subsystem display the related information of the impact by handheld devices and PC; Positioning and tracking subsystem through GPRS network and GPS technology to tracking, positioning and management of equipment.
