摘要
针对目前靶场子弹管理自动化水平不高的现状,本文提出并设计了一种新颖的紫外探测式的子弹统计系统。系统由主机、主节点和两个计数节点组成。计数节点采用"日盲型"的紫外探测器探测子弹火焰中的紫外辐射,背景辐射弱,虚警率很低。子弹信号的A/D转换和计数统计由STM32微控制器实现,功耗极低。相同的硬件结构使得计数节点很容易扩展。主节点在计数节点基础上,增加了串口,与主机通信。主节点与计数节点之间通过CAN总线进行通信。紫外探测式的子弹统计系统可以有效检测子弹连发,计数准确,可靠性好,在靶场实验中取得了很好的结果。
To improve the automation level of bullet management, a novel bullet counting system based on UV electro-optical technology is designed. The system is composed of the upper PC, main node and three counting nodes. In the counting node, UV radiation of bullet flame is detected by ＇solar blind＇ UV detector. Probability of false alarm of the system is low because background radiation of UV is very weak. Bullet signal is converted to digital signal and counted by STM32, a MCU with low power Cost. Counting nodes can be extended easily because they have same the structures. Different from counting nodes, main node has a USART interface to communicate with PC. Main node and counting nodes are connected with CAN bus. The bullet counting system based on UV detection technology can detect bursts of bullets. It＇s a novel, reliable and accurate method and works well at shooting ranges.
