【摘要】：应激(stress)研究在整个人类健康与疾病的领域里,已占据了一个显著的地位。长期处于应激状态会对这类人的健康产生不良影响,尤其是在一些高危作业中,高强度的应激会影响作业人员的正常工作,导致操作失误增多,事故频发。这促使人们渴望了解应激的本质,并探索检测应激的科学方法以及克服它的有效措施。本论文在查阅了国内外相关应激研究文献的基础上,综述了应激对人体的影响,探索并确定了用于应激检测的人体生理参数,自主研制开发了可用于高危作业人员应激状态变化监测的检测系统,并进行了初步的实验验证与分析。本文的主要研究内容包括： (1)通过对人体脉搏波的基波能量进行分析,发现基波能量在人体受到应激时会出现普遍的下降；结合对人体受到应激时体表温度和皮肤电导的生理变化分析,确定了人体应激检测系统的三个生理参数,并给出了三参数人体应激检测系统的总体设计框架。 (2)根据高危作业人员应激检测的便携性和实时性要求,设计开发了三参数人体应激检测系统的下位机硬件系统和上位机软件系统,用于检测人体受到应激时的脉搏波、体表温度和皮肤电导变化。 (3)对设计的系统进行应用测试,通过相关实验初步验证了系统三个生物传感器能够正确检测脉搏波、体表温度和皮肤电导的值,同时又能够检测出人体在受到应激时的三个参数变化。验证了本文设计的三参数人体应激检测系统能够应用于高危作业人员的应激变化监测。最后,总结了本文的主要工作,并对系统研制与开发以及基于人体生理信息的应激状态检测研究与分析进行了展望。
[Abstract]:Stress (stress) research has taken a prominent place in the field of human health and disease. The long-term stress will have a negative impact on the health of this kind of people, especially in some high-risk operations, the high intensity of stress will affect the normal work of operators, resulting in the increase of operational errors, frequent accidents. This makes people eager to understand the nature of stress and explore scientific methods to detect stress and effective measures to overcome it. On the basis of consulting the domestic and foreign literatures of stress research, this paper summarizes the influence of stress on human body, and explores and determines the physiological parameters of human body used for stress detection. A monitoring system for monitoring the stress state of high risk workers was developed, and the preliminary experimental verification and analysis were carried out. The main research contents of this paper are as follows: (1) by analyzing the fundamental wave energy of human pulse wave, it is found that the fundamental wave energy decreases generally when the human body is under stress; Based on the analysis of physiological changes of body surface temperature and skin conductance, three physiological parameters of human body stress detection system are determined, and the overall design framework of three-parameter human body stress detection system is given. (2) according to the portable and real-time requirements of high risk workers' stress detection, the hardware system of the three-parameter human stress detection system and the upper computer software system are designed and developed to detect the pulse wave when the human body is under stress. Changes in body surface temperature and skin conductance. (3) the application test of the designed system is carried out, and the results show that the three biosensors can correctly detect the pulse wave, body surface temperature and skin conductance. At the same time, it can detect the changes of three parameters of human body under stress. The three-parameter human stress detection system designed in this paper can be used to monitor the stress changes of high risk workers. Finally, the main work of this paper is summarized, and the development of the system and the research and analysis of stress state based on human physiological information are prospected.
