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。
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.
