摘要：

为将光纤传感器用于火灾报警中点式温度探测，研究了一种新的点型光纤感温火灾探测器。首先对其工作原理进行分析，然后设计制作其结构，并给出试验结果和可行性分析。结果表明，其技术指标满足国标要求。相对于传统的点型感温火灾探测器，该点型光纤感温火灾探测器采用纯光学方式探测温度变化，其测温元件小、成本低廉、电绝缘性良好、抗电磁干扰、防腐、本质安全、利于批量生产，特别适用于要求防腐防水且为本安型场所的火灾探测报警。

Abstract:  Using optical fiber sensor in point type temperature detection for fire alarm，a new point type optical fiber heat fire detector is studied. First, its working principle is analyzed in detail. Then its structure is designed and produced. The experimental results and feasibility analysis are given. The experimental results show that the technical indexes meet the requirements of national standards. Compared with the traditional point type heat fire detectors, the point type optical fiber heat fire detector adopts pure optical method to detect temperature change. Its merit are included in the following points: small temperature measuring components, low cost, good electrical insulation, antielectromagnetic interference, anticorrosion, intrinsic safety, and being conducive to mass production. This optical fiber temperature sensor is especially suitable for fire detection and alarm in places with anti-corrosion, anti-water and intrinsic safety requirements.
