Abstract

A smart tire-pressure sensing system and an automatic matching method thereof are disclosed. The smart tire-pressure sensing system has a tire-pressure sensor compatible to multiple encoding systems. The tire-pressure sensor is configured to select one of the encoding systems according to a code identification signal so as to have signal communication with a host. The automatic matching method includes: a) installing the tire-pressure sensor compatible to multiple encoding systems to a tire to be monitored; b) inflating the tire to make its tire pressure greater than a preset threshold; c) entering the tire-pressure sensor into an installing process; d) sending a code identification signal to the tire-pressure sensor; e) making the tire-pressure sensor receive the code identification signal and select one of the encoding systems according to the code identification signal; and f) establishing the signal communication between the tire-pressure sensor and the host.

Claims

1. An automatic matching method for a smart tire-pressure sensing system, the smart tire-pressure sensing system comprising at least one host and at least one tire-pressure sensor, the tire-pressure sensor being configured to be installed onto a tire to be monitored, preloaded with a program compatible to a plurality of encoding systems, and thereby capable of selecting one of the encoding systems according to a code identification signal so as to allow the tire-pressure sensor to have signal communication with the host and thereby transmit a measured value of a tire pressure of the tire to the host, and the automatic matching method comprising steps of:

a) installing the tire-pressure sensor into the tire to be monitored;

b) inflating the tire to make the tire pressure thereof greater than a preset threshold;

c) when the tire-pressure sensor detects that the tire pressure is greater than the preset threshold, entering the tire-pressure sensor into an installing process;

d) transmitting a code identification signal to the tire-pressure sensor;

e) making the tire-pressure sensor receive the code identification signal and select one of the encoding systems according to the code identification signal; and

f) establishing the signal communication between the tire-pressure sensor and the host.

2. The automatic matching method of claim 1, wherein in the step d) the code identification signal is sent to the tire-pressure sensor by the host.

3. The automatic matching method of claim 2, wherein the host transmits the code identification signal to the tire-pressure sensor through a wireless transmitter.

4. The automatic matching method of claim 3, wherein the host and the wireless transmitter are connected in a wired manner.

5. The automatic matching method of claim 1, wherein in the step d) the code identification signal is sent to the tire-pressure sensor by a code identifying tool.

6. The automatic matching method of claim 1, wherein the tire-pressure sensor entering the installing process detects and receives the code identification signal.

7. The automatic matching method of claim 1, wherein the signal communication between the tire-pressure sensor and the host is wireless signal communication, so that the tire-pressure sensor I capable of transmitting data of the tire pressure of the tire to be monitored to the host.

8. The automatic matching method of claim 1, further comprising a locking process:

wherein the tire-pressure sensor is locked from entering the installing process again provided the tire-pressure sensor having selected the encoding system has never detected the tire pressure of the tire to be monitored as lower than the preset threshold throughout a signal locking period.

9. The automatic matching method of claim 6, further comprising a recovery process:

wherein a restorer sending a recovery signal to the tire-pressure sensor that had selected the encoding system and has been locked from entering the installing process, so to restart and enter the tire-pressure sensor into the installing process.

10. A smart tire-pressure sensing system, comprising at least one host and at least one tire-pressure sensor, the tire-pressure sensor being installed in a tire to be monitored and being in signal communication with the host, so as to transmit a measured value of a tire pressure of the tire to the host, wherein the tire-pressure sensor is preloaded with a program compatible to a plurality of encoding systems and thereby capable of selecting according to a code identification signal one of the encoding systems so as to allow the tire-pressure sensor to be in the signal communication with the host.
