Research on information fusion technology of multi-mode physical sign sensors for firefighters
To ensure the occupational safety and health of firefight-ers,improve their physical fitness and training effectiveness,re-search is being conducted on the fusion technology of multi sign sensor information for firefighters.In response to the problem that vital sign monitoring equipment is susceptible to harsh environ-ments during firefighting training,significant work movements of firefighters,and interference from personal protective equipment of firefighters,resulting in reduced accuracy of data collection and ineffective or missing data collection,this article adopts the de-sign of multi-mode sensor cross collection to monitor firefighter physical sign indicators.Multi-mode sensors are used to monitor firefighter's electrocardiogram and pulse waves from different posi-tions,and the collected signals are denoised using wavelet thresh-old contraction method and fast sliding mean filtering.Then,fea-ture recognition and fusion are carried out based on the discrete and continuous types of data.After integration,tests were con-ducted in several scenarios such as power bicycles,heavy rain en-vironments,firefighter tire rolling,and drag dummy training,in-dicating a significant improvement in the monitoring accuracy and fault tolerance of the multi-mode vital sign monitoring unit.
