Abstract

A repeater module used in a TPMS and installed in a mother vehicle or daughter vehicle of a tow truck for receiving the status signal from each daughter vehicle tire pressure sensor and providing a corresponding wireless signal to the on-vehicle main unit in the mother vehicle by using the ID code and communication protocol of any mother vehicle tire pressure sensor so that the mother vehicle can receive the status information of the tires of the daughter vehicle without needing to modify the on-vehicle main unit.

Claims

1. A repeater module used in a tire pressure monitoring system and selectively installed in a mother vehicle or daughter vehicle of a tow truck for receiving a status signal from a daughter vehicle tire pressure sensor in each daughter vehicle tire and providing a corresponding wireless signal to an on-vehicle main unit in said mother vehicle, the repeater module comprising:

a MCU;

a memory unit electrically connected to said MCU and adapted for storing an ID code and communication protocol of at least one mother vehicle tire pressure sensor;

a transmitter unit electrically connected to said MCU and adapted for transmitting a wireless signal to said on-vehicle main unit in said mother vehicle;

a receiver unit electrically connected to said MCU and adapted for receiving a status signal from each said daughter vehicle tire pressure sensor; and

a power source electrically connected to said MCU to provide the repeater module with the necessary working electricity.

2. The repeater module as claimed in claim 1, further comprising an alarm unit electrically connected to said MCU and controllable by said MCU to give off an alarm signal.

3. The repeater module as claimed in claim 1, further comprising a switch electrically connecting said power source to said MCU and switchable to turn on/off the repeater module.

4. The repeater module as claimed in claim 1, wherein said transmitter unit and said receiver unit are configured to operate on the same frequency.

5. The repeater module as claimed in claim 2, wherein said transmitter unit and said receiver unit are configured to operate on the same frequency.

6. The repeater module as claimed in claim 1, wherein said transmitter unit and said receiver unit are configured to operate on different frequencies.

7. The repeater module as claimed in claim 2, wherein said transmitter unit and said receiver unit are configured to operate on different frequencies.

8. The repeater module as claimed in claim 1, wherein said power source comprises a power cable connectable to said mother vehicle to obtain electricity from said mother vehicle.

9. The repeater module as claimed in claim 1, wherein said transmitter unit is adapted to transmit a wireless signal to said on-vehicle main unit in said mother vehicle when the status signal from one said daughter vehicle tire pressure sensor is abnormal.

10. The repeater module as claimed in claim 1, further comprising a connection port for enabling the repeater module to be connected to external means for ID code or communication protocol modification.

11. The repeater module as claimed in claim 2, further comprising a connection port for enabling the repeater module to be connected to external means for ID code or communication protocol modification.
