船用烟火信号光强测试技术研究

救生信号弹是民用船只海上救生的必要设备，其质量的好坏直接关系到人身安全。根据照度距离平方反比定律，结合光电技术和计算机辅助技术，研究救生信号弹的信号光强测试，构建测试系统。通过编写的测试软件，将测得的信号直接输入计算机，并直观地显示结果。实现了简易、快速测量救生信号弹发光强度和遮光率的目的。实验证明：该系统稳定可靠，并且符合生产企业生产过程在线检测的需要。

Light-intensity test technique for pyrotechnical signal on merchant ship

Since the lifesaving signal detonator is an essential marine lifesaving appliance in the merchant ships,its quality is critical to personal safety. Based on the illuminance inverse-square law,incorporated with photoelectric technology and computer-aided technology,a test system was set up. The test for the signal light intensity was investigated. The detected signal data was directly input to the computer and displayed on the screen through the test software. The easy and fast test of the light intensity of the lifesaving signal detonator was realized. The experiment proves that this system is robust and reliable,and meets the demand of the on-line test in the production process of the lifesaving signal detonators.
