Abstract

The invention provides a detectable and active direction-finding positioning system and a positioning method. The system comprises a detectable module carried by an underground operator and an activedirection-finding positioning module used by a rescuer. The detectable module comprises a passive tag and an antenna, and corresponding personnel information and a unique identification code are written into the detectable module; the active direction-finding positioning module comprises a core control unit, a human-computer interaction unit, an SOS alarm interaction unit, a battery protection unit and a detection antenna, wherein the human-computer interaction unit, the SOS alarm interaction unit, the battery protection unit and the detection antenna are connected with the core control unit;the detection antenna is used for detecting the detectable module and receiving the personnel information and the unique identification code when the detectable module is detected; and the SOS alarm interaction unit is used for giving a prompt when the detectable module is identified. The detectable module can be resistant to metal interference, is small and thin in size, can be embedded into mostof products, and the personnel database information can be recorded; the rescue personnel adjust the detection interval, the search range is narrowed step by step, and accurate positioning of the rescued personnel is achieved.

Description

technical field [0001] The invention relates to the technical field of mine rescue equipment, in particular to a detectable and active direction-finding positioning system and positioning method. Background technique [0002] At present, the human search and rescue technologies mainly include: wireless technologies such as RFID, wifi, and Bluetooth can realize active positioning, and active positioning requires personnel to wear positioning cards equipped with batteries, while infrared detection technology and microwave technology can realize passive positioning of the human body search and rescue. [0003] According to domestic literature search, passive positioning mostly stays in theoretical research. Applying UHF-RFID technology to passive search and rescue, and performing fast small-area positioning and detection when the equipment is without power, there is no related application for the time being. [0004] The patent "A Smart Watch for Personnel Search and Rescue" ...
