Problems solved by technology

The disadvantage of this indoor positioning system is that at least one wireless transmitting device and positioning signal transmitting device must be installed inside each required floor. The cost is high and the actual operation is difficult. When the power is off, the wireless transmitting device cannot work, and the positioning cannot be realized

Abstract

The invention discloses an indoor accurate positioning system and a method thereof. The method comprises the following steps: an air pressure sensor module, an electronic compass module and an electronic pedometer module are added based on the existing mobile terminal positioned by virtue of a GPS; when a GPS signal disappears, the mobile terminal transmits starting-point coordinate information, real-time air pressure information, two-dimensional plane azimuth information and mobile step-number information to a background server by a wireless network; and storey and position information of the mobile terminal are obtained by calculation on the background server and a storey map and specific positions are shown by the mobile terminal. In the invention, any wireless transmitting equipment and positioning signal transmitting equipment do not need to be preset indoors, thus achieving positioning in some specific storey in indoor environment with multiple stories and accurate positioning in some specific position on the storey; and the invention has high precision, lower cost and strong practicability.

Description

technical field [0001] The invention relates to an indoor positioning system and a realization method. Background technique [0002] At present, the positioning service represented by the Global Positioning System (Global Positioning System, GPS) has been widely used in many fields. However, due to the shielding effect of the building, there is no GPS signal or the signal is very weak in the indoor environment, so the GPS signal cannot be used for positioning. [0003] The application number is 200810032837.9, the publication date is July 29, 2009, and the invention patent application with the publication number CN101493510A discloses an indoor positioning system and method. The indoor positioning system needs to include a handheld device and more than one wireless transmitting device. In an indoor environment with multiple floors, the wireless transmitting devices are respectively arranged in the multiple floors, and transmit different floor identification signals respecti...
