Abstract

Timely acquisition of location information of people in distress is an important prerequisite for successful rescue. This paper analyzed the application status of the emerging Internet of Things technology-LoRa in the field search and rescue system, and designed a field rescue system based on LoRa and Beidou. LoRa positioning technology was used as the auxiliary positioning means of satellite positioning technology, which was used to solve the problem of satellite positioning accuracy decline when the line-of-sight condition could not be met. Finally, the IDEF0 function modeling of the system has a certain engineering significance.
