基于GSM网络和数据融合技术的远程火灾报警系统设计

Design of Long Range Fire Warning Device Based on GSM Network and Data Fusion technology

利用DS18B20数字温度传感器、MQ-2烟雾传感器探测环境参数,采用数据融合技术对多个传感器采集到的数据进行处理和识别,不仅弥补了采用单一传感器的不足,而且很大程度上降低系统判断结果的不确定性,提高了系统预警的准确性和可靠性.设计一种基于GSM/GPRS网络的远程火灾报警器的系统构成、工作原理,并给出了系统的软、硬件设计和功能实现.实验结果表明:以GSM模块为基础的远程火灾报警器,可以缩短火灾报警时间,有效发挥消防设施作用,迅速扑灭火灾,为火灾远程报警提供了一种实用的联网技术方案.

Smoke sensor,DS18B20 digital tempreture sensor and MQ-2 smoke sensor are combined as a whole to detect the condition.The data acquired by the multi-sensor is processed by data fusion tech-nology.The method not only makes up insufficiency of single sensor,but also reduces the uncertainty of j udgment result and enhances the accuracy and reliability of the fire early alarm system.This paper introduces the working principle,software and hardware design,and the function of long-distance fire disaster warning device based on GSM network.The device can decrease warning time and help to bring fire fighting facilities into full play,which offered a pragmatic network technique for long dis-tance fire disaster warning.
