Tire pressure monitoring system
First Claim
1. A tire pressure monitoring system adapted for installation in a vehicle for detecting tire pressures of vehicle wheels of said vehicle through tire pressure sensors respectively installed in the vehicle wheels of said vehicle and capable of wirelessly transmitting detected tire pressure data in the form of a data packet, said tire pressure monitoring system comprising;
- a monitoring main unit adapted to be disposed near a driver'"'"'s seat of said vehicle for enabling a driver of said vehicle to monitor the operation status of each vehicle wheel of said vehicle;
a plurality of receiving antennas adapted to be installed in a bottom side of said vehicle, each said receiving antenna being adapted to receive a wireless communication signal transmitted from at least one said tire pressure sensor nearby; and
a plurality of combiners, each of which has two input terminals and an output terminal, said combiners including at least one first combiner and at least one second combiner, the two input terminals of said first combiner being respectively electrically connected to two said receiving antennas and the output terminal of said first combiner being electrically connected to one of said input terminals of said second combiner and the output terminal of said second combiner being electrically connected to said monitoring main unit so that the wireless communication signals received by said receiving antennas are transmitted through said at least one second combiner to said monitoring main unit through a wired transmission path.

Abstract
A tire pressure monitoring system includes receiving antennas installed in a vehicle corresponding to vehicle wheels, a monitoring main unit disposed near a driver'"'"'s seat, tire pressure sensors respectively installed in the wheels of the vehicle to wirelessly transmit detected data in the form of a data packet for being received by one corresponding adjacent antenna, and a signal combining circuit formed of multiple combiners and having multiple input terminals electrically connected to the receiving antennas and an output terminal electrically connected to the monitoring main unit for combining data packets received from the receiving antennas and transmitting the combined data signal to the monitoring main unit by means of a wired transmission path.
