PROBLEM TO BE SOLVED: To correctly manage the arrangement position and shape of electronic equipment in a space of a room or a warehouse. SOLUTION: Each of sensors 21, 22, 23 broadcast-transmits a beacon signal (BEACON), e.g., into a managed object space and uses an acknowledge signal (ACK) corresponding to the beacon signal for detecting a device ID of each device 31 and a distance from each device 31. A host device 11 detects the position of each device 31 in accordance with the distance from each device 31 detected by each of the sensors 21, 22, 23 and the position of each of the sensors 21, 22, 23. Besides, the host device 11 uses the device ID for executing radio communication with each device 31 to acquire shape information from each device 31. COPYRIGHT: (C)2005,JPO&NCIPI |
