TIRE PRESSURE MONITORING SYSTEM WITH BIDIRECTIONAL COMMUNICATION FUNCTION
First Claim
1. A tire pressure monitoring system with bidirectional communication function, comprising:
- a plurality of sensing units being separately mounted on tires to be monitored, said tires being separately located at a head portion and a body portion of a vehicle, and said head portion and said body portion being integrally connected to one another;
each of said sensing units including at least one pressure sensor, a microprocessor, a third power supply, and a third wireless transmitter;
said pressure sensors being adapted to sense tire pressures of said tires to be monitored;
said microprocessor being adapted to integrate and process the tire pressures of said tires being monitored, and send signals indicating the tire pressures to said third wireless transmitter;
said third wireless transmitter being adapted to wirelessly transmit the received tire pressure signals; and
said third power supply supplying power needed by said at least one pressure sensor, said microprocessor, and said third wireless transmitter;
a first wireless module being mounted on said body portion of said vehicle, and including a first wireless receiver and a first wireless transmitter;
said first wireless receiver being located near a rear end of said vehicle body portion farther from said head portion for receiving tire pressure signals transmitted by said sensing units on said tires nearer the rear end of said body portion;
said first wireless transmitter being located near a front end of said vehicle body portion closer to said vehicle head portion for receiving tire pressure signals from said first wireless receiver, and then wirelessly sending out the tire pressure signals; and
a second wireless module being mounted in the vehicle head portion, and including a second wireless receiver and a display unit;
said second wireless receiver being adapted to receive tire pressure signals sent by said first wireless transmitter, and said display unit being adapted to receive said tire pressure signals from said second wireless receiver so as to display the tire pressures of said tires being monitored.
