Tire administration system
First Claim
1. A tire administration system comprising:
- a sensor module secured to an inner side of a tire mounted on a vehicle, for measuring a tire state quantity and transmitting a measured data to a vehicle body side; and
a receiver module secured to the vehicle body side, for transmitting a data request signal at a predetermined period so as to request said measured data to said sensor module, and for receiving the measured data transmitted from said sensor module;
wherein said receiver module is configured so as to (i) transmit said data request signal to said sensor module at a frequency used for a latest, successful acquisition of said measured data, (ii) transmit said data request signal to said sensor module if said measured data cannot be acquired, repeatedly until said measured data is acquired, and (iii) transmit said data request signal to said sensor module, if the number of transmission of said data request signal reached a designated number of transmission, at a frequency used for a second latest, successful acquisition of the measured data.

Abstract
A tire administration system selects a frequency of a high reception probability, when a measured data request signal is transmitted from a receiver module (1) to a sensor module (3), or when a frequency of the data request signal is changed, so as to promptly acquire a measured data from the sensor module (3). The receiver module (1) transmits the measured data request signal to the sensor module (3), at a frequency used for a latest, successful acquisition of the measured data from a sensor module (3), transmits the measured data request signal, if the measured data cannot be acquired, repeatedly until the measured data can be acquired, and transmits, if the transmission number of the measured data request signal reaches a designated transmission number, the measured data request signal to the sensor module (3) at a frequency used for a second latest, successful acquisition of the measured data.

4. A tire administration system comprising:
-
a sensor module secured to an inner side of a tire mounted on a vehicle, for measuring a tire state quantity and transmitting a measured data to a vehicle body side; and a receiver module secured to the vehicle body side, for transmitting a data request signal at a predetermined period so as to request said measured data to said sensor module, and for receiving the measured data transmitted from said sensor module; wherein said receiver module is configured so as to (i) transmit said data request signal to said sensor module at a frequency of a channel of a first highest reception probability for the measured data, (ii) transmit said data request signal to said sensor module if said measured data cannot be acquired, repeatedly until said measured data is acquired, and (iii) transmit said data request signal to said sensor module, if the number of transmission of said data request signal reached a designated number of transmission, at a frequency of a channel of a second highest reception probability for the measured data.
