TN9红外温度传感器在火灾报警系统中的应用
摘要
基于AT89C52单片机与TN9红外温度测量模块
设计出了一种大范围实时火灾监测智能报警系统。与传统的火灾报警系统相比
该系统采用一个TN9红外模块即可检测30 m以内的火灾情况
监控范围广
精度高
同时节约了经济成本
可实现大范围火灾报警。实验结果表明:与传统报警系统相比
该系统对温度和烟雾体积分数的测量精度与范围均明显改善
完全可以满足现代工厂等火灾易发区的火灾报警需求。
Abstract
A wide area and real-time fire monitoring alarm system based on AT89C52 and TN9 infrared temperature measurement module is designed.The system uses a TN9 infrared module which can detecte the conflagration within 30m
it has wide monitoring area
high precision and low cost
thus
wide areas fire darm can be monitored.The test results show that compared with the conventional alarm system
the measurement precision and area on temperature and volume fraction of smoke of the new system are significantly improved
it fully meets the demands of the modern fire-prone areas in factory.
