Abstract
A tire pressure measure system and method make use of the UWB wireless transmission technique in a local environment of a vehicle to measure the tire pressure of a vehicle. The tire pressure measure system has at least a data fetch terminal and a host control terminal. The data fetch terminals are disposed on at least a tire aircock of a vehicle. A user can operate the host control terminal to get the tire pressure values of a vehicle via the data fetch terminals by means of the UWB wireless transmission technique.
Claims10
A tire pressure measure system making use of UWB technology and used in a local environment of a vehicle, said tire pressure measure system comprising:
- at least a data fetch terminal disposed on at least a tire aircock, said data fetch terminal comprising:
- a pressure message fetch unit connected to said tire aircock and used to get a tire pressure signal;
- an analog/digital conversion unit connected to said pressure message fetch unit and used to receive and convert said tire pressure signal into a digital tire pressure signal;
- a data processing unit connected to said analog/digital conversion unit and used to process digital signals;
- and
- a first UWB communications module connected to said data processing unit and a first antenna and used to receive a remote inquire signal and emit a reply signal via said first antenna;
- and
- a host control terminal comprising:
- a micro control unit for processing digital signals;
- a second UWB communications module connected to said micro control unit and a second antenna and used to emit said inquiry signal and receive said remote reply signal via said second antenna;
- and
- an operational unit connected to said micro control unit and operated by a user to send a control signal to said micro control unit.
A tire pressure measure method making use of UWB technology, comprising the steps of:
- performing inflation of at least a tire of a vehicle;
- using a tire pressure meter to measure a tire pressure signal of each of said tires;
- installing at least a data fetch terminal on aircocks of said tires;
- using a host control terminal to set a serial number of each of said data fetch terminals and said tire pressure signal of each of said tires to be a set tire pressure value;
- storing said serial numbers and said set tire pressure values in a memory unit;
- using said host control terminal to send an inquiry signal to said data fetch terminals;
- receiving in turn said tire pressure signals obtained by said data fetch terminals;
- using said host control terminal to process said tire pressure signals to become said set tire pressure values;
- and
- displaying said set tire pressure values on a display unit.
