Wireless tire pressure monitoring system with interactive multiple frequency channel
First Claim
1. A wireless tire pressure monitoring system, comprising a controlling host module and a plurality of tire detection units;
- the controlling host module including;
a first central processing unit (CPU);
a key unit electrically connected to the first CPU for setting a default standard value;
a display unit electrically connected to the first CPU;
a low-frequency wireless transmitter electrically connected to the first CPU for transmitting a low-frequency signal to the tire detection units and thereby informing the tire detection units to return current tire information; and
a high-frequency wireless receiver electrically connected to the first CPU for receiving the tire information returned by the tire detection units and sending the received tire information to the first CPU; and
the tire detection units being separately provided on tires of a transport vehicle, and each including;
a second CPU;
a tire information detecting device electrically connected to the second CPU for detecting tire information;
a low-frequency wireless receiver electrically connected to the second CPU for receiving the low-frequency signal transmitted from the low-frequency wireless transmitter of the controlling host module; and
a high-frequency wireless transmitter electrically connected to the second CPU for transmitting a high-frequency signal to transmit the tire information detected by the tire information detecting device to the high-frequency wireless receiver of the controlling host module.

Abstract
A wireless tire pressure monitoring system with interactive multiple frequency channel includes a controlling host module and multiple tire detection units. The controlling host module includes a first CPU, a key unit, a display unit, a low-frequency wireless transmitter, and a high-frequency wireless receiver. The tire detection units are separately provided on tires of a vehicle and each include a second CPU, a tire information detecting device, a low-frequency wireless receiver, and a high-frequency wireless transmitter. A default standard value may be set via the key unit. The low-frequency wireless transmitter transmits a low-frequency signal to each of the low-frequency wireless receivers for requesting the tire detection units to transmit current tire information, which is then sent via a high-frequency signal transmitted by the high-frequency wireless transmitter to the high-frequency wireless receiver.
