PROBLEM TO BE SOLVED: To surely track an automatic machine even when it is carried away from a predetermined fixed place. SOLUTION: When the automatic machine 1 is removed from a predetermined installation place, an anomaly sensor 12 of the sensor board unit 10 detects the fact and sends it to a monitoring center 4 side. The sensor board unit 10 periodically sends positional information or the like acquired on the basis of a GPS signal to a monitoring center 4. In the monitoring center 4, an alarm is issued by a rotating warning lamp 43, and the positional information is lapped over a map and displayed on a displaying part 422. By this, position of the automatic machine 1 being carried away by a truck TR or the like can be surely tracked. COPYRIGHT: (C)2004,JPO
