Base station layout is carried out according to the actual area and environment of indoor rooms, corridors and stairs in the hospital. Through the base station, it is connected into a whole positioning network to ensure that each area can achieve high-precision positioning. People with labels can achieve high-precision seamless indoor positioning between each room and each positioning unit.
Hospital staff and patients can also locate valuable medical machinery.
1）UWB positioning label: positioning card and positioning bracelet worn by staff and patients;
2）UWB base station: receive the location data sent by the tag, and the base station is fixed in the set area of the hospital;
3）System software platform: information display and data management, early warning, etc., for integrated intelligent digital management.
After receiving the location tag signal, the UWB base station transmits the data to the location server after calculation. The location engine software in the location server displays the location of the personnel and displays the specific location through the electronic map.The point connected by each position becomes the behavior track.
Main functions of the system
1）In the case of static personnel, the positioning accuracy is less than or equal to 0.3m, the basic probability is 96.28%, and there may be some deviation in the case of special needs.
2）The positioning accuracy of the system is about 0.3-0.5m when people are in dynamic activities.
3）The system is for industrial application, and can work continuously without affecting normal use.
4）There is no 6-8ghz or nearby wireless signal in the field, the system is not interfered, and there is no interference to the original wireless signal band in the field.
5）When the UWB 30cm signal passes through the wall, there will be a certain error, about around.
6）It can locate the exact position in real time and view it in real time.
7）Electronic fence, track playback, early warning and other comprehensive applications.
