Research On Body Temperature Wireless Monitoring System Based On Mobile Phone

In recent years,with the development of medical profession,the widespread use of smart phones and wireless communication technology become more mature,the mobile medical monitoring applications,the technology can real-time monitoring a patient's physical condition,has important significance for disease monitoring,especially the temperature.Temperature is one of the most information to measure the human body health,currently,mercury thermometer measure body temperature is commonly used in medical institutions,and temperature curve is drawn through manual recording,observe the patient's body temperature trend.In this way not only takes time and manpower,but also with a lag,changes in body temperature can't be found timely.In order to solve this problem,realize real-time monitoring of temperature,this paper designs and completes the wireless body temperature monitoring system based on mobile phone.Main work of this subject includes the following four aspects:First of all,according to the demand of the system design,select the appropriate temperature sensor,wireless communications and mobile phone development platform to complete the overall design of the system.Secondly,build the body temperature acquisition and transmission platform.The platform includes three aspects of temperature measurement circuit,temperature acquisition and Bluetooth wireless transmission.Temperature measurement circuit using YSI₄00 temperature probe to achieve temperature measurement,temperature acquisition and transmission are using TI CC2540F256 microprocessor as the main control chip,connecting the temperature measurement circuit and the main control chip to achieve temperature signal acquisition and transmission.Again,design of Android mobile phone client application.The application mainly to achieve temperature signal receiving,display temperature data and plotted as a curve,data storage and data review and other functions,which receives the temperature signal is divided three steps: to scan for Bluetooth,Bluetooth connectivity and data transmission.To ensure the medical staff can detect changes in the patient's temperature,the Android mobile phone client also designed the SMS alarm function,when the patient questions above a certain temperature,system will send text messages to mobile phone number of the set,in order to make timely treatment to patients.Finally,through the experiment analyses reliability of the temperature data acquisition and Bluetooth wireless transmission quality,while processing and analyzing of temperature signals,to provide the basis for the user and the medical staff analysis condition.
