Research On Indoor Robot Complex Positioning System Under The Winternet

Research on Indoor Robot Complex Positioning System under the WInternet, Inorder to achieve the geomagnetic map building, Kalman filter, real-time positioning, thewireless communication and geomagnetic sensor technology are combined. Compared toultrasound positioning technology optical tracking system、 Bluetooth、Wi-Fi and otheradvanced technologies, the system has certain advantages in precision, anti-interferenceability, timeliness,etc. In addition, the mobile robot positioning system in largesupermarkets, terminals, exhibition, warehouses, airports and other indoor places of thefire hall has a broad application space, In this paper, in order to meet the market demand,We studied the indoor and outdoor wireless location and achieving certain results.(1) In this paper, studies the Bluetooth APP has instant messaging capabilities.Through AT command control module HC-06and use the serial port and timer interruptsbased on52chip smart car.(2) Research on indoor positioning technology based inertial navigation aidsgeomagnetic, analysising of geomagnetic matching algorithm, attitude solver algorithmand asking a main design indoor positioning topics.(3) Research on Real-time location-based Kalman filter algorithm under WInternet,Discrete stochastic differential equations, Kalman gain, a posteriori state covariance andverify the validity of multiple iterations to optimize RSSI model Kalman.(4) By combining the geomagnetic information to optimize the design of Internetenvironment program, using wireless sensor planning and positioning of the local area.In this paper, the use of geomagnetic information matches prior to build geomagneticreference map in order to achieve the purpose of saving time cost.(5) In this paper, the design of indoor and outdoor seamless positioning technologybased on Android, By receiving and storing GPS signals,Analytical geographicinformation, Google Map Design, Enable users to parse out the latitude and longitudepositioning.Physical analysis of experimental data obtained in this paper describes a compositepositioning has good positioning accuracy and positioning timeliness.
