Design And Implementation Of Mobile Application Based On Health Big Data Platform

The Health Big Data Platform is the exploration which combining with big data technology and health.Briefly introduce the Health Big Data Platform,it provides a unified data access for users' variable portable terminal devices,and offers an efficient and safe way of organizing data for them.The Health Big Data Platform can record a user from birth to die all information related health,include at least four kinds of the most common health data: data from wearable devices,data from intelligent equipment,chronic disease data and data from medical institution.The Health Big Data Platform can not only provide accurate health guidance for the users,but also have research on chronic disease.Therefore,this article has designed and developed a healthy mobile application based on The Health Big Data Platform.The main work is reflected in the following two aspects:First,considering the complexity of the clinical data structure and the accuracy of the content,we can not directly show clinical data on the mobile devices.It is necessary to design a document structure to realize the exchange and expression of clinical data.This article refers to the HL7 CDA(clinical document architecture)standard then design a document structure which more suitable for mobile application.According to this document structure.we generate clinical files which called "mobile electronic medical records." Then use XSTL technology to convert the realized mobile medical record XML document into XHTML and realize the visual requirements of the mobile electronic case.Second,this article designs and implements a mobile application that allows users to “quantify themselves” based on the Health Big Data Platform,providing users a new way of health management.First of all,according to the characteristics of the application,the smart monitoring device data and the clinical data of medical institutions are selected as the data sources for mobile applications.For different characteristics of these two different kinds of data,choose different ways to express them.For the monitoring data,the key is to express its dynamic changes in a period of time.This paper selects Echarts charts to show.For the clinical data,we design “.XSL” file to make the mobile electronic medical records display results as same as the paper medical records.This application uses hybrid mode to develop.Socket is used to complete the data exchange between the client and the server.DES and RSA are used to ensure the security of the data transmission process.
