A positioning monitor device, method and system

According to the positioning monitor device, method and system of the invention, information of a first position scope where a monitored terminal is located is positioned and displayed, and a compass is provided so as to provide a direction reference for approaching a monitor terminal. When external equipment approaches the monitor terminal and gets into the scope of wireless communication, wireless communication connection between the external equipment and the monitor terminal is established so as to generate second positioning signals to determine a second position scope of the monitor terminal in the first position scope, and information of the second position scope is displayed. When the external equipment approaches the monitor terminal, gets into an induction scope and senses the monitor terminal, induction signals are generated so as to generate specific positional information of the monitor terminal and display the specific positional information. Through cooperative running of a plurality of positio
