The present invention provides a method and system for preventing a neonate from being stolen in a hospital, so as to effectively prevent the neonate from being stolen in the hospital. The system comprises a positioning server, a wrist strap label worn on the body of a neonate, and at least three base stations connected to and synchronous with each other. The wrist strap label is used for sending ultra-wideband pulse signals to the at least three base stations. The base stations are used for receiving the ultra-wideband pulse signals sent by the wrist strap label and sending, to a positioning server, time points of receiving the ultra-wideband pulse signals. The positioning server is used for positioning, according to a positioning algorithm and the time points of the at least three base stations separately receiving the ultra-wideband pulse signals, the neonate wearing the wrist strap label, and for sending alarm information to a central server when the neonate is taken away from a preset range. The technical solution provided in the present invention is unlikely to be interfered by environmental disturbance and can make a neonate in a hospital positioned highly precisely; in another aspect, the location of the neonate at a time point can be obtained, so that the neonate can be effectively prevented from being stolen in the hospital. |
