The Design And Implementation Of GPS-based Children’s Real Time Positioning Control System

The fast pace of urban life， make some parents take care of young children less time，prone to child care vacuum，go out and abducted children lost the frequently occurred，havecause parents， society， government departments of the high attention. In order to betterensure the safety of the children， to eliminate the parents to their children safety concerns，and let parents know that children at any time and place where children， a real timepositioning system can satisfy the demand custody.This system is the orientation of the GPS and GSM/GPRS module personal distancepositioning device. Built-in GPS chip， GPS/LBS positioning switch， outdoor， indoor GPSpositioning the automatic positioning，ensure the automatic LBS any time any where can realtime positioning. Special circumstances，be finished by SOS key telephone，sending aid callfor help text messages， send for help position the operation MMS. Can be set up some timestealth， such as Monday to Friday at8：30to11：30and14：30to16：30every day two timeintervals realize locking keys and mute. It can be set up for four family numbers， after thesuccess of a two-way conversation can be a key phone， children could use it simply. Bindingnumber can be set inbound access permission， just family numbers can call in.Developing a set of special children’s real time positioning monitoring system based onKalman filtering navigation and positioning algorithm will be an effective way to solve thisproblem， eliminate the trouble back at home of parents at any time to realize the youngchildren of all kinds of information. It can be the emergency， displacement alarm， alarm，low electric fence alarm. There can also be calling function， instant orientation， positionregularly， remote monitor. It can be set when the monitor number is be called by theterminal，it will automatically be answered，thus plays listening effect. Sending SMS powermay be revealed.The children complete real time positioning monitoring system is completed in thisthesis. After a certain testing tests， it has basically completed the functions described indemand performance goals，been deployed applications in one of the children kindergartens，and realized the good economic benefits. Whereas owing to system user operationconvenience， remind the alarm to the timely and effective， positioning information accurately， to the user operation convenience and good security guard， it will also becarried out in more development application in kindergartens.
