基于多传感器信息融合的无线火灾定位报警系统

The wireless fire alarm and positioning system based on multi-sensor information fusion

利用短距离无线通信技术设计了一个分布式火灾定位和报警系统。该系统主要由控制模块、探测模块、无线通讯模块和报警模块组成。分布在不同区域的探测模块采用多传感器对火灾信息进行探测,根据Neyman-Pearon准则对多传感器的信息进行融合。当判断有火灾发生时,探测模块通过nRF24L01+把火灾信息发送给控制模块,以蜂鸣器鸣叫和液晶屏显示两种方式提醒人们火灾发生。同时该火灾报警系统利用GSM模块向控制中心或消防部门报警并告知火灾发生的地点。经测试,该系统性能可靠,无需布线,适用于各种公共场所的火灾监测和定位。

A distributed fire positioning and alarm system was designed using the short - range wireless communication technology. The system mainly consisted of control module, detection module, wireless communication module and alarm module. The detection module distributed in different regions detected fire information making use of multi - sensor, and fused the multi - sensor information according to the Neyman - Pearon criterion. When the detection module judged that a fire had occurred, it sent the fire information to the control module through the nRF24L01 ＋o And people were reminded of the fire by the buzzer beep and the LCD displaying. At the same time, the fire alarm system carried out the alarm and informed the control center or the fire department of the fire location using the GSM module. The experiment confirmed that the system was reliable and needed no wiring. The system designed was suitable for the fire monitoring and positioning of various public places.
