Abstract

The invention relates to a positioning system, in particular to an indoor positioning system which comprises a radio frequency signal emitter, a controller, an ultrasonic receiver and a microprocessor, wherein the radio frequency signal emitter, the controller and the ultrasonic receiver are respectively and electrically connected with the microprocessor; and wireless communication is adopted between the radio frequency signal emitter and the controller as well as between the controller and the ultrasonic receiver. The system is simple in structure, low in cost and high in positioning precision and can be widely applied to various indoor positioning fields.

Description

technical field [0001] The invention relates to a positioning system, in particular to an indoor positioning system. Background technique [0002] Nowadays, people increasingly need various location services, most of which are used for outdoor positioning. With the continuous development of technology, increasing computing power and miniaturization of hardware, users can use them anytime and anywhere, and indoor location services are becoming more and more important. [0003] With the rapid increase of communication services and data services, people's demand for positioning and navigation is increasing, especially in complex indoor environments, such as hospitals, airports, exhibition halls, warehouses, supermarkets, libraries, underground parking lots, etc. , often need to determine the location of various personnel in the room. However, limited by conditions such as positioning time, positioning accuracy, and indoor complex environments, relatively complete positioning ...
