Abstract

The existing indoor positioning methods of firefighters are generally based on GPS single positioning data, but in complex indoor environment, the signal stability is reduced and the positioning accuracy is not high. In order to improve the stability of positioning signal and optimize the accuracy of positioning data in indoor environment, a method of indoor positioning for firefighters based on GPS and sensor network was proposed. According to the differences of GPS positioning data and sensor network, the uncertain information transition analysis model, and then according to the continuity of the two data model is calculated, and the GPS and the sensor network data exchange noise reduction calculation, GPS and indoor positioning signal sensing network latency difference correction, GPS and indoor positioning signal fusion calculation of sensor networks. The simulation results show that the indoor positioning error of the proposed method is only 1.23%, which is more suitable for the indoor application scenarios of firefighters.
