Abstract

The invention relates to a positioning system and a positioning method based on a UWB, RFID and INS multisource joint positioning technology. The system comprises a positioning terminal, a UWB positioning module, an RFID positioning module and an INS positioning module, wherein the UWB positioning module sends UWB signals to the positioning terminal, whether UWB signals forwarded back by the positioning terminal meet a preset positioning requirement is judged, if yes, a related algorithm in TDOA and AOA positioning estimation is adopted to acquire the position of the positioning terminal, and if not, the RFID positioning technology and the INS positioning technology is adopted to acquire the position of the positioning terminal. Reliable positioning service is provided for indoor emergent rescue activities, the rescue time is saved, the rescue activity success rate is improved, and the system and the method of the invention can be widely applied in the public safety field.

Description

technical field

[0001] The invention relates to a positioning system and a positioning method based on UWB, RFID, and INS multi-source joint positioning technology, and belongs to the technical fields of public security and space positioning. Background technique

[0002] In an increasingly modern society, the degree of informatization and intelligence in people's lives is changing with each passing day. With the development of the economy, a series of densely populated areas such as large-scale convenience places, entertainment places, shopping places, and workplaces integrating catering, shopping, entertainment and other functions have emerged. For this kind of specific environment, the population density is high, the environment structure is complex, and people’s knowledge of the area is limited. would cause great economic losses. At the same time, the complex indoor environment structure has also imposed a burden on rescue activities. When carrying out rescue activiti...
