PURPOSE:To provide the mobile body management system by which the management of the location of a mobile body such as a truck is realized with a few persons at a low cost. CONSTITUTION:A radio telephone set 3 mounted on each mobile body 2 receives a latitude/longitude coordinate positioning signal from a satellite 6 to generate latitude/longitude coordinate information and converts the information into a DTMF signal. Then a management center makes a call automatically via a radio line 4 to the radio telephone set 3 mounted on each mobile body 2 to acquire the latitude/longitude coordinate information converted into the DTMF signal from each mobile body 2 and displays the position of each mobile body 2 on a map pattern based on the latitude/longitude coordinate information. |
