1. A wireless sensing system of a seat position, comprising:
a slave control unit provided for each seat to detect a seat belt fastening status and a seat occupancy status by a passenger; and
a master control unit provided in a vehicle to receive data based on a radio signal of the slave control unit through radio communication with the slave control unit for each seat, calculate a position of the slave control unit for each seat based on the data received through radio communication, and discontinue a position checking of the slave control unit by turning off a check switch for selecting to check the slave control unit when it is determined that the position of the slave control unit calculated for the slave control unit for each seat is outside the vehicle,
wherein the master control unit is configured to calculate the position of the slave control unit for each seat using a plurality of position calculation methods different from each other based on the data obtained through the radio communication and to determine that the slave control unit is positioned outside the vehicle when the positions of the slave control unit calculated by each of the position calculation methods match and the calculated position of the slave control unit is out of a designated position range, and
wherein the slave control unit is configured to be diagnosed as having a failure when the positions of the slave control unit calculated using the plurality of position calculation methods do not match.
