基于最小参数集的特殊环境下远程生命状态的识别

The remote detection and health warning for people， who are under specific environment such as outdoor and porehole operation, field exploration, disaster relief and battlefield, have important significance on effective accurate treatment and， rescue task adjustment and deployment. Under special circumstances, the rescuer''s and rescuer''s lives and health information are often difficult to obtain, and the traditional means of communication is often very difficult to play a role, generally using a special way, such as satellite and other means of communication to deal with it. Meanwhile, large amounts of data often cause network congestion and data loss. Therefore, it is necessary to solve these problems by reducing the redundancy of the parameters of life and health information and the amount of communication data. The project aims to research new methods to extract parameters from uncertain and noise-added health information, to explore the minimum parameter set and minimum data transmission comprehensively representing health conditions in the special environment, to construct health assessment models for life body in special environment,and to seek methods to obtain. All above progress will further improve healthy care for rescuee and rescuer, and enhance the treatment level for the sick and the wounded in special environment.

户外探险、井下作业、抢险救灾及战场等特殊环境下人员的生命信息远程检测、健康预警对该类人员的健康监测、伤病员的有效精确救治和施救任务的调整部署具有重要意义。由于特殊环境的限制，救援者和被救援者生命健康信息通常较难获取，而且传统的通信手段不能有效地将生命体征信息传递到指挥调度中心。卫星等特殊通信方式不受地理条件的影响，然而大数据流量往往造成通信链路堵塞以及数据丢失。因此，有必要通过降低生命健康信息参数的冗余性、减少通信网络中的数据量流量来解决上述问题。本项目研究旨在研究特殊环境下各种生命健康信息参数的提取方法；探索适用于特殊环境下的能较全面表征人体生命健康状态的最小参数集合；建立针对特殊环境下生命体的健康评估系统；以期望提升特殊环境下作业人员和被救人员的健康关护和伤病员的救治水平。

本项目的主要研究成果为：提出了基于定位系统和地图服务的野外多人同步搜寻方法；并启动了基于该方法的软件项目。该方法可以有效地提高野外搜索的效率，同时防止出现搜寻区域的遗漏。. 在野外搜寻（可以是寻人或寻物），特别是多人联合野外搜寻中，经常发生两种情况：. 1.多人重复搜索同一区域导致搜寻效率不高。. 2.漏掉搜寻某一个区域，导致搜寻盲区。. 本方法使用定位系统记录每个人的搜索路径，并使用中央服务器将所有搜索路径进行存储以及分发,使得每个人都可以知道整个搜索的覆盖情况，并可以根据该结果有效规划下一步的搜索计划。.基于本方法的软件系统主要包括两个部分：一个部分是服务器，提供搜寻软件的网络服务支撑；另一部分是客户端，整合了定位系统和地图资源，同时与服务端进行交互。
