Description
Summary:In view of the problem of big position error of personnel positioning system based on RSSI technology, the paper proposed to use triaxial acceleration sensor built-in smart phone to collect active vibration signal, and get walking motion law of the human through data analysis with reference to body movement, so as to achieve pedometer operations. The passed wireless access point was taken as a reference to achieve accurate positioning combined with RSSI ranging method. The test results show that the combination of RSSI ranging technology and pedometer ranging can effectively improve positioning accuracy.
