Embodiment Construction

[0034] see figure 1 , which is a deployment diagram of the wireless indoor positioning system of the present invention. The wireless indoor positioning system provided by the present invention deploys some fixed nodes in the place to be positioned, and completes the positioning of the target through these fixed nodes, which includes a plurality of wireless nodes 10 as fixed nodes, and a vehicle-mounted terminal 11 as the target node , the mobile smart terminal 12 and the server 13 are connected by wireless communication links between each unit. The wireless nodes 10 can be deployed in a cellular manner, so as to ensure signal coverage. A user can connect to a nearby fixed node through a smart mobile terminal 12, such as a smart phone supporting Bluetooth 4.0. The smart mobile terminal 12 can download corresponding fixed point node information from the server 13 . The smart mobile terminal 12 can send a corresponding command to obtain the location of the vehicle terminal 11 ...

Abstract

The invention relates to a wireless indoor positioning system and method. The wireless indoor positioning system includes: multiple fixed wireless nodes, a vehicular terminal, a mobile intelligent terminal and a server; the wireless nodes are mounted in a to-be-positioning situation and are numbered respectively according to positions; the server is used to respectively establish communication with the mobile intelligent terminal and the vehicular terminal; the vehicular terminal responds to an instruction forwarded by the server, and acquires and uploads a current number of a first wireless node of the vehicular terminal; and in positioning, the mobile intelligent terminal carries out the navigation and positioning according to a pre-stored electronic map of the to-be-positioning situation, and a combination of the first wireless node and a location of a second wireless node of the mobile intelligent terminal. The invention also provides a wireless indoor positioning method. The wireless indoor positioning system and method of the invention do not rely on the GPS positioning, and is simple, reliable, and highly practical.

Description

technical field [0001] The invention relates to positioning technology, in particular to a wireless indoor positioning system and method. Background technique [0002] GPS is the abbreviation of Global Positioning System (Global Positioning System) in English. It is a system that uses GPS positioning satellites to perform positioning and navigation in real time around the world. It is currently the most popular positioning system. At the same time, my country has also launched the Beidou satellite positioning system that can replace the GPS system. The positioning principles of the GPS system and the Beidou satellite positioning system are both based on triangulation. [0003] At present, the vehicle positioning device based on the GPS system is widely used in the positioning, anti-theft, monitoring and dispatching of buses, freight vehicles, taxis, etc. But unlike the outdoor environment, the GPS will fail indoors or in streets and canyons lined with tall buildings. The G...
