Abstract:
1. A tire condition monitoring method for measuring a physical property value in a tire by a sensor of a sensor module mounted in the tire, transmitting data of the physical property value from the sensor module at a desired time interval, receiving the data from the sensor module by a receiver, and monitoring the physical property value based on the data received by the receiver; the method comprising the steps of: processing send data by first determining at the sensor module whether an amount of change with respect to a previous value of a measured value of the physical property value from the sensor exceeds a threshold, and, if determined that the amount of change with respect to the previous value of the measured value exceeds the threshold, at least one flag is set in a packet of the send data from the sensor module; and processing received data by second determining at the receiver whether an amount of change with respect to a previous value of the measured value of the physical property value of received data from the sensor module exceeds a threshold, and, if determined that the amount of change with respect to the previous value of the received data does not exceed the threshold, determining at the receiver whether the flag is set in the received data; and using the received data if determined that the flag is included in the received data, and discarding the received data if determined that the flag is not included.
