基于压电薄膜和片上可编程系统的可穿戴体征监测系统

Wearable vital signs monitor based on piezoelectric film sensors and PSoC

随着社会经济的发展,人口与建筑密度日益增大,火灾发生的概率越来越大,扑救难度也越来越高。传统的消防防护服属功能服装只能实现防火,隔热和阻燃等基本功能。而消防战斗员的生命体征无法被消防指挥员及时获知,这对保障消防战斗员的生命安全,和消防现场的应急指挥非常重要。正是在这种形势下,可穿戴体征监测系统的研究才具有重要的实用意义。研究的可穿戴体征监测系统,是可装配于救援防护服本体上,基于压电薄膜技术和片上可编程系统技术搭建的,具有生命体征监测和告警功能的电子系统。装配了该系统的救援防护服,不仅能够实现传统防护服对救援队员的保护作用,还可以实时监测救援队员的生命体征,通过声光告警电路将现场信息反馈给救援队员,提高了消防救援和指挥效率。

With the development of social economy, population and building density increases day by day, the probability of fire is more and more big, the difficulty to save is also more and more high. The traditional fire protective clothing can only achieve fire prevention function, heat insulation and basic function such as flame retardant. And fire fighters＆#39; vital signs cannot be acquired by commander in time, this is very important to ensure the life safety of the fire fighters and to command the scene of the fire emergency. In this situation, the study of the wearable vital signs monitoring system is importantly of practical significance. The wearable vital signs monitoring system, which is equipped on the rescue protective clothing ontology, based on the piezoelectric film and the programmable system chip technology, has the vital signs monitoring and warning function of electronic systems. The rescue protective clothing equipped this system, can not only realize the traditional protective function to rescue team members, can still monitor the vital signs of the rescue team members in real-time. Through the sound and light alarming circuit, the field information can feedback to rescue team members, thereby increasing the efficiency of fire rescue and command.
