(S32). If they do not match (S32: NO), the arithmetic circuit 11 terminates the process, and upon receiving the trigger signal, restarts the process from S31. If they match (S32: YES), the arithmetic circuit 11 acquires position information by the position information acquisition circuit 15 (S33). Arithmetic circuit 11 associates the device identification information with the position information and stores them in storage device 12 as related information (S34). After that, the arithmetic circuit 11 can repeat S31 to S34 to create a database having position information in which each measurement sensor 30 is embedded.
