摘　　要：分析远距离紫外火灾探测系统的系统工作原理和探测距离的影响因素,设计光学聚焦机械结构,实现对远距离火灾的监测。试验结果表明,系统将现有的紫外探测器探测距离从100 m提升到了上千米,系统探测距离远、保护面积大、响应速度快、灵敏度高。与图像型火灾探测系统相比,系统同样适于大空间火灾探测报警,且具有更高的性价比和灵活性。The principle and the function elements of the remote ultraviolet fire detection system were studied.The focusing lens was designed to realize the long distance fire detection function.The experiment manifested that it can improve the detecting range from 100 m to 1000 m.The system has features such as wide range,short response time and high sensitivity.Compared with other feasible wide space video fire detection method,it is more flexible and economical.
