  • Sensing apparatus, time alignment apparatus, time processing method, and time alignment method
    Patent number: 9526079
    Abstract: A sensor, a time alignment apparatus, a time processing method, and a time alignment method are provided. The sensor begins to sense at least one sensed data at a first local time instant. The sensor transmits a response message at a second local time instant. The response message carries the at least one sensed data, the first local time instant, and the second local time instant. The time alignment apparatus receives the response message at a first global time instant. The time alignment apparatus calculates a second global time instant that the at least one sensed data being sensed according to a required transmission time between the time alignment apparatus and the sensing apparatus, a clock skew rate between the time alignment apparatus and the sensing apparatus, the first global time instant, the first local time instant, and the second local time instant.
