according to the intensity change information of different positioning signals received by the fusion base station (3), the master control module of the fusion base station (3) switches the RFID, UWB or Bluetooth positioning modes;
when a fusion base station (3) is arranged at a clean passage, an entrance of an operating room, an entrance of a corridor and an entrance of an equipment room, the personnel area tracking is realized by adopting the RFID tag positioning;
when the medical equipment or personnel are in a long-distance mobile environment, the master control module of the fusion base station (3) switches the UWB positioning mode;
when a plurality of fusion base stations (3) receive single or multiple positioning data of RFID, UWB and the bluetooth of a certain positioning label respectively, and when single signal source can't accomplish accurate positioning, upload the positioning data received to edge gateway (4), carry out the positioning data comparison and the calculation of crossing the signal by the calculation module of edge gateway (4) through fusing the positioning algorithm, obtain final positioning data.
4. The system for locating and managing medical devices and personnel according to claim 1, wherein: the equipment positioning and data acquisition device (1) transmits the running state or medical detection data of the medical equipment acquired through the serial port to the fusion base station (3) through the Bluetooth or UWB module, and uploads the data to the management and control platform (5) after being processed by the edge gateway (4).
5. The system for locating and managing medical devices and personnel according to claim 1, wherein: the management and control platform (5) sends out equipment operation instructions manually or periodically, the equipment operation instructions are transmitted to the edge gateway (4) through the WLAN, the edge gateway (4) determines the types and objects of the instructions, and the fusion base station (3) and the equipment positioning and data acquisition device (1) are controlled to initiate position active reporting instructions for the medical equipment.
