Abstract

A tire pressure detecting apparatus has an identification rewriteable tire pressure detector and a setting apparatus. The tire pressure detector is securely mounted on a valve stem inside a tire of a vehicle and has a micro-processing module, a sensing module, a transmitting module and a receiving interface, where the micro-processing module has a memory unit. The setting apparatus is capable of reading or inputting an identification from a failure tire pressure detector, transmits the identification to the identification rewriteable tire pressure detector and writes the identification into the memory unit.

Claims

1. A tire pressure detecting apparatus comprising:

an identification rewritable tire pressure detector comprising;

a micro-processing module having a rewritable memory unit being capable of recording an identification;

a sensing module electrically connected to the micro-processing module and having a pressure-detecting unit, the pressure-detecting unit detecting a tire pressure and sending a detection result to the micro-processing module;

a transmitting module controlled by the micro-processing module to transmit a radio frequency (RF) signal comprising the detection result and an identification of the identification rewritable tire pressure detector;

a power module electronically connected to the micro-processing module and providing electric power to the identification rewriteable tire pressure detector; and

a receiving interface electronically connected to the micro-processing module, receiving and sending an external signal to the micro-processing module, where the external signal comprises an external identification to be written into the rewriteable memory unit; and

a setting apparatus communicating with the identification rewriteable tire pressure detector and having a control module;

an input module being electronically connected to the control module and allowing an operator to input an identification to be written into the identification rewriteable tire pressure;

a receiving module electronically connected to the control module, receiving the RF signal from the identification rewriteable tire pressure detector or a tire pressure detector and sending the RF signal to the control module;

a setting output module controlled by the control module to send the external signal to the receiving interface, where the external signal is generated by the control module and comprises the identification that is provided by the input module or provided by the RF signal received from the receiving module; and

a power source electronically connected to the control module and providing electrical power to the setting apparatus.

2. The tire pressure detecting apparatus as claimed in claim 1, wherein

the receiving interface is a connector;

and

the setting output module is an outputting connector corresponding and being electronically connected to the receiving interface and sends the external signal to the receiving interface.

3. The tire pressure detecting apparatus as claimed in claim 1, wherein

the receiving interface is a low frequency receiver and receives the external signal wirelessly;

and

the setting output module is a wireless transmitting interface sending the external signal wirelessly to the receiving interface.

4. The tire pressure detecting apparatus as claimed in claim 1, wherein the input module is a dip switch.

5. The tire pressure detecting apparatus as claimed in claim 1, wherein the sensing module further has at least one acceleration-detecting unit and a temperature-detecting unit.
