摘要：消防员生命安全监测系统是一种在消防员的灭火过程中实时监测消防员生命安全状态的检测系统，目的是最大化避免更大的伤亡，对保障消防员的生命安全和抢险救灾具有极大的意义。

本课题针对消防员安全的监测系统是在复杂多变的火场环境下运行，同时需要动态的监测消防员的生命体征数据的情况。设计了一种满足此种条件的生命监测系统，系统采取多向对比的设计方法，在充分借鉴国内外类似设计经验，将系统设计为三个大的模块，即数据采集模块，数据分析模块和综合判断模块，包括硬件的传感器模块，具体包含姿态传感器，心率传感器和温度传感器，能够实现对消防员三个基量的采集，姿态的判别算法模块实现了对消防员的加速度转化为姿态角的判断，最后的消防员安全综合检测的模块实现了对消防员在火场中是否安全的综合判断。

通过以上三个模块的综合协同工作，经过最后的仿真实验结果的验证，监测系统能够实时了解被检测的消防员的工作状态，从而判断出被测消防员的安全指数，心率、运动姿态等信息，通过多级警报的方式，对消防员的状态实现多级预警，实时控制，实现整个消防员生命体征检测系统的功能，最大化的避免伤亡，从而确保消防员的火场生命安全。

Abstract：Firefighter life safety monitoring system is a firefighter in the process of fire extinguishing real-time monitoring of fire safety status of the detection system, the purpose is to maximize the avoidance of casualties, to protect the lives of firefighters and disaster relief has great The meaning of.

The safety monitoring system for firefighters is carried out in a complex and volatile environment, and the vital signs of firefighters are monitored dynamically. So that the unity of convenience and reliability. So the appropriate sensor selection method, to the simple and simple attitude analysis algorithm and visual display and other methods, the system is pided into three large modules, namely the hardware sensor module, including the attitude sensor, heart rate sensor and temperature sensor , The software aspects of the identification of the attitude of the algorithm module and the final crew of the fire safety detection comprehensive judgment module.

Through the above three modules of the integrated work together to the entire monitoring system to understand the safety status of a fireman, can comprehensively reflect a fireman's safety index, heart rate, sports attitude and other information, through multi-level alarm, The number of firefighters to achieve multi-level early warning, real-time control links to achieve the entire firefighters vital signs detection system functions, so as to ensure that the fireman's fire life safety

Keywords: Multi - axis acceleration sensor ; Motion attitude algorithm; Safety index
