Abstract

The invention disclose an indoor positioning system and an indoor positioning method based on three-dimensional multipoint wireless and micro-inertia navigation as well as an expansion type indoor control system. The indoor positioning system comprises a calibration device and a sensing device, wherein the calibration device comprises at least three first wireless transceiver units used for sending signals at intervals of first preset time; and the sensing device comprises an inertia sensing unit, a second wireless transceiver unit and a processing unit, wherein the inertia sensing unit is used for sensing the motion of a target object, the second wireless transceiver unit is used for producing a response signal when receiving the signal transmitted by each first wireless transceiver unit, and the processing unit is used for respectively calculating a first space coordinate of the target object according to the motion of the target object sensed by the inertia sensing unit, calculating a second space coordinate of the target object according to the response signal, and combining and processing the first space coordinate and the second space coordinate to obtain the final space coordinate of the target object. With the adoption of technical schemes of the indoor positioning system and the indoor positioning method, the positioning accuracy is high, and the motion response of the target object is sensitive, and the response rate achieves the millimeter.
