Air pressure management device for vehicle tire and vehicle tire capable of outputting air pressure information

摘要

A wireless communication device includes an electric power generation unit, an electric power accumulation unit, a sensor supplied with the electric power from the electric power accumulation unit, and a wireless communication unit supplied with the electric power from the electric power accumulation unit, for transmitting the sensed information outputted by the sensor to outside of the wireless communication device. A storage unit stores the sensed information outputted by the sensor. A control unit controls operation of the wireless communication unit, the sensor and/or the storage unit in accordance, at least in part, with the electric power accumulated in the electric power accumulation.

1. A wireless communication device comprising:
an electric power generation unit; an electric power accumulation unit for accumulating electric power generated by the electric power generation unit; a sensor supplied with the electric power from the electric power accumulation unit to output sensed information; a wireless communication unit supplied with the electric power from the electric power accumulation unit, for transmitting the sensed information outputted by the sensor to outside of the wireless communication device; a control unit for causing at least one of the sensor and the wireless communication unit to suspend the function thereof until the electric power accumulated in the electric power accumulation unit becomes sufficient for the function of at least the one of the sensor and the wireless communication unit; and a storage unit for storing the sensed information outputted by the sensor, wherein the control unit causes the storage unit to store the sensed information outputted by the sensor, and the wireless communication unit to suspend the transmission until the electric power accumulated in the electric power accumulation unit becomes sufficient for the function of the wireless communication unit, and wherein the control unit causes the sensor to output again sensed information if a predetermined period of time or longer has elapsed from a time of the output of the sensed information stored in the storage unit when the electric power accumulated in the electric power accumulation unit becomes sufficient for the function of the wireless communication unit.
