Research And Application Of Real Time Monitoring System For Individual Vital Signs In Company Training

Personal physical causes or overload training results in the danger of soldier's life,the danger happens occasionally in the forces of high strength training and causes serious problems,however the current technology for real-time monitoring of soldier's health has not applied to the forces.Based on these questions,the real-time monitoring system of soldier's vital signs was designed and realized in this paper,which was used to help commanders to control the physical condition of soldiers in real time,accurately and rapidly,and ensure the safety and order of training.According to the indicator of individual vital signs accepted in medical field,firstly the body temperature was gathered by a temperature sensor with high precision,strong anti-interference ability and the digital and analog interface circulation.The system was used the secondary development of reflection type photoelectric sensor to collect pulse,and gathered data processing unit at high speed through the low power,and used master-slave encryption module to send human data to gathering mobile terminal,enduring the accuracy and security of the data acquisition.Secondly,using the high speed buffer storage technology,the gathering mobile terminal achieved the function of rapidly receiving Bluetooth data and forwarding data in real time to cloud server.In order to speed up the transmission speed,the data structure was designed between acquisition unit and mobile terminal to fixed length,and in order to improve data reliability,long connection was used between mobile terminal and cloud server.Once more,the data was send from gathering mobile terminal to monitoring mobile terminal in real time by using fast forwarding technology,and deployed the high concurrency Java procedure based on Apache MINA frame on the cloud server,and tested the properties of forward program through the pressure test software Apache JMeter,it could be concluded that the cloud server performance can meet the requirements of concurrent access to one thousand users.In the meantime,data structures using “comma” interval was designedin the communication between mobile and cloud server terminal,and accelerated the speed of data processing.Finally,the mobile system of vital signs monitoring was designed to complete the function of body data,it can be displayed and updated in real timeand added the error processing algorithm based on least square method to quickly fit in nearest five groups of vital signs data,predict the range of target range and weed out the error data because of system itself.The system has been used in three battalions and three companies continued for four months,during the period,it has warned five accidents caused by racing heart risk.It endures the security of people in forces,reduces the depletion of numbers without combat,andprovides guarantee for forces to carry out the training,competition in military skills and evaluation of one's performance.System at the same time can also be applied in social medical field,and provide the convenience for doctor to grasp the patients' condition in real time,and deal with emergency timely.
