Abstract

The invention discloses a wifi-based indoor positioning system. The wifi-based indoor positioning system comprises a service terminal and a client side, the service terminal and the client side are connected through internet, the client side comprises a laptop and a mobile terminal, the laptop is connected with the internet through an internet access point, the mobile terminal is connected with the internet through a GPRS, the service terminal comprises a web server, a database, a positioning server and a router, and the web server, the database and the positioning server are mutually connected through a local area network and are finally connected with the internet through a router. The wifi-based indoor positioning system provided in the invention adopts the local area network to perform data connection between all the parts of the service terminal, a positioning error brought by a random disturbance of a signal intensity indication is overcome, and positioning precision is improved. The system has the advantages of simple structure, reasonable design and high applicability.

Description

technical field [0001] The invention relates to a positioning system, in particular to a wifi-based indoor positioning system. Background technique [0002] In recent years, with the development of wireless communication technology and the widespread deployment of various wireless networks, positioning technology based on short-range wireless communication technologies such as wifi has received more and more attention because it not only has no line-of-sight requirements, but also does not need to build additional expensive positioning infrastructure. At present, positioning technology based on short-range wireless communication technologies such as wifi has become a useful supplement to satellite positioning such as GPS, and is especially suitable for applications in closed and semi-closed scenarios such as indoors and underground. [0003] Therefore, there is a lack of an indoor positioning system with small positioning error and high positioning accuracy. Contents of ...
