Embodiment Construction
[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0048] The positioning and track navigation method and system based on the LTE small base station and PDR provided by the present invention are composed of an intelligent terminal, an LTE small base station, and a positioning server, such as figure 1 shown.
[0049] The smart terminal refers to a terminal device that supports LTE, a camera, a nine-axis sensor, and an air pressure sensor, and the fire-fighting positioning service APP needs to be installed on the smart terminal device. The Fire Positioning Service APP is the operator of the positioning algorithm. It collects information from LTE RSS, cameras, nine-axis sensors, and air pressure sensors, and then calculates the position of firefighters based on these information, and returns the positioning results to the server. The smart terminal needs to be worn on the chest of the firefighter. A typic...
