Objective:The hospital space positioning system for patients and the medical staff,which is used to achieve the goals of spatial orientation,is a new application of ward management. Methods:The system uses the RFID tag as the core and the RF8506 as the reader unit,which constitutes the ZigBee terminal device with the CC2530 wireless single-chip computer. The terminal devices were placed in the ward entrance to recorded whether the patients went out of the room. The network was set up by coordinator,and positioning and display function were realized by computers. Conclusion:The space positioning system can be seen as a fuzzy space positioning. It is different from video surveillance and the existing flat pinpoint ways such as GPS,because it protects the patient’s privacy and it achieves the regional location of floor space. From above,the system can simplify the management of hospital ward and reduce the workload of medical staff.
