Abstract: Disclosed is a portable axle scale system using a smart terminal. In the portable axle scale system, a portable smart terminal functions to judge whether or not a vehicle is overloaded based on a result measured by a portable axle scale, and to transmit a variety of information, such as information on the measured vehicle, personal information on a vehicle driver, photographs related to a measurement operation, and positional information on a measurement place, to a server for storage of the information. Then, the smart terminal may transmit the information to a cellular phone or other communication terminals of the vehicle driver to assist the vehicle driver in confirming relevant materials in real-time.
