Research On The Home Care Elderly Health Monitoring And Emergency Accident Decision-making Support Based On GIS

In2011,the population aged60and above rose2.93%compared with2000which accounted for13.26%and aged65and above that contain80%empty-nester rose1.91%compared with2000which occupied8.87%of the total population, according to the sixth nationwide census from the national bureau of statistics.This has showed our aging process is accelerated.The elderly could not be taken good care of by thier children because of the current family planning policy, economic environment and competitive situation which made the offsprings don’t have time or ability,besides, temporarily the elderly can not totally rely on the government.Hence, the birth of home-based care services model is expected to solve the above problems. With the development of society,what children concern most are thier parent’s physical status and the emergence measurement when suddenly happened.The national "Twelfth Five Year Plan" which aims to improve the level of city management and the quality of serving the people by means of information requires to develop city informatization construction and wisdom city construction.The paper, which is based on the GIS technology, RFID indoor positioning technology and semantic inference technology and also based on the platform of digitalcity by means of city construction, using the Internet, video surveillance and communication technology, can be summarized in the following three aspects:(1) The creation of the physiological indexes of elderly people and infectious disease ontology inference rule base, and the establishment of the essential standard and optional table can make the diagnosis diseases and timely warning come true.(2) The precondition of studyiing multiple path calculation model is to consider the time-varying and complexity of the road situation.The proposition of the genetic algorithm based medicine feeding model can compare with the static algorithm and quickly calculate the best-route to hospital which the target is to the road impedance minimum and the intersection delay time of minimum two goals.Compared with the relative use of traditional GIS (Geographic Information System) path analysis and computational modeling,the simulation practice in the comprehensive solution of the GIS design platform make more Reference Modeling divisors into accout.And this algorithm has a better open system which can caculate the best-route quickly.(3) The proposition of the LANDMARC algorithm based on improved RFID equipment has a indoor position solution which can accurately locate the elderly in fire scene. According to the positionof building staff, fire and poison smoke spread,safety exit and corridors and stairways network,the maximum dynamic Connected graph and the shortest path solution of dynamic escape or rescue pathway can be analysed by seeing the fire and poison as a breakpoint and lead to the proposition of RFID-based emergency rescue command model and the solution plan in a sudden fire.Compared with the traditional ant colony optimization evacuation model and social force model,this model can effectively help to solve the problem of unknown combustion and smoke in fire scene and the undetective location of the elderly. The escape probability in fire scene can increase when the scene of the fire can be known and effective activation command is made.
