METHOD AND APPARATUS FOR PROVIDING POWER TO MULTIPLE ANTENNAS OF AUTOMATIC FARE COLLECTION SYSTEM

摘要

A method and an apparatus for providing the power to the multiple antennas of automatic fare collection system are provided to prevent the distortion of interference in response to the simultaneous power supply of the antenna by selectively supplying the power to only one antenna. An apparatus for providing the power to the multiple antennas of automatic fare collection system includes a power supplying unit(200) and a controller(100). The power supplying unit(200) supplies the power by selecting one among a plurality of antennas. The controller(100) controls the power supplying units(200) so as to select one among the plurality of antennas. The power supplying units(200) are provided with an RF module or an ASIC. And, a plurality of the power supplying units(200) exist corresponding to the plurality of antennas or one power supplying units(200) is connected to the plurality of antennas respectively to manage integrally.
