ELECTRONIC TIRE MANAGEMENT SYSTEM |
摘要 |
An electronic tire maintenance system is provided for measuring a parameter of a device at a first location. The system includes a sensor (18) for measuring the device parameter and generating a data signal representing the measured parameter. The system also includes a microprocessor (16) coupled to the sensor (18) fo r activating the sensor (18) on a first periodic basis to measure the device parameter. T he microprocessor (16) includes a memory for storing the generated data signal representing the measured parameter. A transmitter/receiver (21) is coupled to the microprocessor (16). The microprocessor (16) periodically partially awakens to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so , fully awakens and responds to the valid interrogation signal, via the transmitter, by at least transmitting the last stored measured parameter. In one embodiment, the device is a tire tag (14) mounted inside a tire that measures tire data and transmits that data to a remote source (26) in response to an interrogation request, an alert condition, or automatically o n a periodic basis. |
