Patent ID: 11329744

Abstract:
According to one embodiment, a transmission terminal, a time information processing device, and a synchronization method capable of improving synchronization accuracy in a wireless network are provided. According to an embodiment, a sensor system includes a sensor, a transmission terminal, and a time information processing device. The transmission terminal includes an event signal generator, an event time determiner, a communication time determiner, and a communicator. The event signal generator detects the occurrence of an event on the basis of a physical quantity detected by the sensor. The event time determiner determines a detection time of the event. The communication time determiner determines a transmission time at the time of transmission to the time information processing device. The communicator transmits time information to the time information processing device. The time information processing device includes a reception time determiner and a time information processor. The reception time determiner determines a reception time of the time information transmitted from the transmission terminal. The time information processor performs a process based on a plurality of transmission times and a plurality of reception times.
