Abstract

The invention discloses a rail-transit underground-station indoor positioning and navigation system. The system comprises a positioning and navigation server, wireless access points and a mobile terminal. The plurality of wireless access points are distributed at different positions in a rail-transit underground-station indoor place. The positioning and navigation server stores wireless access point information of each position and exhaustive navigation lines. The mobile terminal scans a BSSID and an RSSI of each wireless access point and sends the BSSID, the RSSI and a MAC address of the mobile terminal to the positioning and navigation server. The positioning and navigation server compares data acquired from the mobile terminal to stored data so as to form positioning and navigation to the mobile terminal. The mobile terminal and the wireless access points adopt wireless communication based on a protocol IEE 802.11a, IEE 802.11b, IEE 802.11g or IEE 802.11n. The invention also discloses a rail-transit underground-station indoor positioning and navigation method. By using the system and the method of the invention, a positioning scope is large; cost is low and mobile terminal access is convenient.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to an indoor positioning and navigation system for an underground rail transit station; in particular, it also relates to an indoor positioning and navigation method for an underground rail transit station. Background technique [0002] In complex indoor environments, it is often necessary to determine the accurate location information of people or objects. Many indoor positioning technologies, such as A-GPS positioning technology, ultrasonic positioning technology, Bluetooth technology, infrared technology, radio frequency identification technology, ultra-wideband technology, wireless local area network, light tracking positioning technology, as well as image analysis, beacon positioning, computer vision positioning Technology and so on technology came into being. [0003] The more mature technologies currently on the market mainly include the following: [0004] 1) Infrared indoor po...
