Abstract

The tire pressure monitoring device has a storage module, a receiver module and a control module. The tire pressure monitoring device retrieves a protocol by external indication or internal discrimination. The external indication is that the control module retrieves a protocol from the storage module according to an external signal, and then the control module compares the retrieved protocol with a protocol of a tire pressure signal received by the receiver module. If a comparison of the protocols matches, the tire pressure monitoring device decodes the tire pressure signal. The internal discrimination is that the control module compares different protocols stored in the storage module with a protocol of the tire pressure signal. If a comparison of the protocols matches, the tire pressure monitoring device decodes the tire pressure signal.

Claims

1. A tire pressure monitoring device capable of receiving tire pressure signals with different protocols, the tire pressure monitoring device comprising:

a receiver module receiving a tire pressure signal from at least one tire pressure sensor;

a signal receiver module receiving an external signal from an external control device;

a storage module being rewritable and at least one protocol being written and stored in the storage module according to the external signal; and

a control module connected to the storage module, the receiver module and the signal receiver module, wherein the control module retrieves one of the at least one protocol stored in the storage module according to the external signal to decode the tire pressure signal received by the receiver module.

2. The tire pressure monitoring device as claimed in claim 1, wherein multiple protocols are written and stored in the storage module, and the external signal includes an instruction for controlling the control module to retrieve one of the protocols stored in the storage module.

3. The tire pressure monitoring device as claimed in claim 1, wherein the control module is connected with a display module displaying a tire pressure value by decoding the tire pressure signal from each one of the at least one tire pressure sensor, and when the tire pressure value detected by each one of the at least one tire pressure sensor does not match a preset value, the display module generates a warning.

4. The tire pressure monitoring device as claimed in claim 1, wherein the control module is connected with a transfer module for encoding or converting the decoded tire pressure signal and then transmitting the tire pressure signal to other external devices.

5. A tire pressure monitoring device capable of receiving tire pressure signals with different protocols, the tire pressure monitoring device comprising:

a receiver module receiving a tire pressure signal from at least one tire pressure sensor;

a storage module being rewritable and storing multiple protocols; and

a control module connected with the storage module and the receiver module, the control module comparing the tire pressure signal received by the receiver module with the protocols stored in the storage module, and then retrieving a matched protocol from the protocols stored in the storage module to decode the tire pressure signal.

6. The tire pressure monitoring device capable of receiving tire pressure signals with different protocols as claimed in claim 5, wherein the control module is connected with a signal receiver module receiving an external signal from an external control device, and the external signal has an instruction for controlling the control module retrieving one of the protocols stored in the storage module.

7. The tire pressure monitoring device capable of receiving tire pressure signals with different protocols as claimed in claim 5, wherein the control module is connected with a signal receiver module receiving an external signal from an external control device, the external signal includes a specific protocol and a storage instruction corresponding to the specific protocol, and the storage module stores the specific protocol according to the storage instruction.

8. The tire pressure monitoring device capable of receiving tire pressure signals with different protocols as claimed in claim 5, wherein the control module is connected with a display module displaying the decoded tire pressure signal from each one of the at least one tire pressure sensor, and when the tire pressure value detected by each one of the at least one tire pressure sensor does not match a preset value, the display module generates a warning such as an audio warning or a visual warning.

9. The tire pressure monitoring device capable of receiving tire pressure signals with different protocols as claimed in claim 5, wherein the control module is connected with a transfer module encoding the decoded tire pressure signal, and the transfer module encodes the decoded tire pressure signal or converts the decoded tire pressure signal and then transmits the tire pressure signal to other external devices.
