1. A tire pressure monitoring system comprising:
- a monitoring unit positioned in a tractor, a first repeater positioned in the tractor, a plurality of second repeaters positioned in a plurality of trailers connected to the tractor, and a plurality of sensors positioned at tires of the tractor or the trailers, whereinthe monitoring unit includesa first RF transceiving unit transmitting an auto coupling request, a destination identification (ID) change request, and configured data and receiving a first received signal strength indicator (RSSI), a repeater identification (ID), a sensor identification (ID), and sensed data with the first repeater, the plurality of second repeaters, or the plurality of sensors through a radio frequency band,a low power RF transmitting unit transmitting a repeater ID request to the plurality of second repeaters through a low power radio frequency band,an LF transmitting unit transmitting data to the plurality of second repeaters through a low frequency band,a first control unit sensing abnormal data receiving in the first RF transceiving unit, anda display unit outputting connection information for the second repeater received through the first RF transceiving unit,wherein transmitting and receiving power of the first RF transceiving unit is higher than transmitting power of the low power RF transmitting unit,in the case where the second repeater having the maximum value of a first received signal strength indicator (RSSI) values measured through the plurality of second repeaters and the second repeater having the maximum value of a second RSSI values measured through the monitoring unit coincide with each other, the destination ID change request is transmitted to the corresponding second repeater.
