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...

Abstract

The invention relates to an LTE and PDR-based fire-fighting indoor positioning and track navigating method and system. The system comprises an intelligent terminal, an LTE small base station and a positioning server, wherein the intelligent terminal is terminal equipment supporting LTE, a camera, a nine-axis sensor and an air-pressure sensor; fire-fighting positioning service APP is installed on the intelligent terminal equipment, is an operator of a positioning algorithm, and is used for collecting information of the LTE RSS, camera, nine-axis sensor and air-pressure sensor, calculating the position of a firefighter according to the information, and returning the positioning result to the server; the LTE small base station is a small cell of a mobile communication system for covering indoor signals, and is used for providing data service link and assistant positioning to a smart mobile phone in the positioning system. The method and system have the beneficial effects that a communication and positioning environment can be quickly constructed by utilizing the LTE small base station and the intelligent terminal, the field arrangement system is convenient, and the implementation of the system can be greatly increased.

Description

technical field [0001] The invention relates to the positioning field of information technology, in particular to a method and system for positioning and trajectory navigation in a fire fighting room based on LTE and PDR. Background technique [0002] Fire positioning technology is to ensure the safety of firefighters entering the fire scene, determine the position of firefighters in the fire field, ensure the effective rescue of firefighters in distress in the fire field, and ensure the effective movement monitoring of firefighters in the fire field by commanders and other fire fighting and rescue work It is an urgent problem to be solved and has a good application prospect. [0003] Compared with ordinary positioning technology, fire positioning technology has its particularity, manifested in the following aspects: First, fire positioning scenes generally occur indoors, and rarely occur outdoors. Outdoor positioning can be solved with the Global Positioning System (GPS), ...
