Abstract

The invention provides an indoor positioning system which comprises two infrared receiving strips provided with a plurality of infrared receivers, four infrared transmitters which transmit infrared detection signals in a time division manner and a positioning processing device electrically connected with the infrared receivers. The two infrared receiving strips are oppositely arranged, the four infrared transmitters are respectively arranged at two ends of the two infrared receiving strips, and the infrared receiving strips and the infrared transmitters are on the same plane. The infrared receivers receive infrared signals sent by the two opposite infrared transmitters, and the connecting lines of the opposite ends of the two infrared receiving strips and the two infrared transmitters form a detection zone. The coordinate of a tested object in the detection zone is determined by the positioning processing device according to the position coordinate of the infrared transmitters arranged in the detection zone, the position coordinate of the infrared receivers and the condition of the infrared signals received by the infrared receivers. The indoor positioning system is convenient to use, and the cost of the system is reduced under the condition of meeting the requirement for same positioning accuracy.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to an indoor positioning system. Background technique [0002] The current indoor positioning system mainly uses ultrasonic positioning and wireless sensor positioning and so on. Install multiple transponders indoors, and install or wear a signal transmitting device on the object or person to be tested. After receiving the signal sent by the signal transmitting device, the transponder returns a response signal to the signal transmitting device, and then determines the waiting time according to the delay time of the response signal. Measure the distance between the object and the transponder, so as to determine the position of the object to be measured. [0003] Since the indoor positioning systems in the prior art all need to install or wear a signal transmitting device on the object or person to be measured, it is very inconvenient to use. Moreover, to achieve a certain posit...
