Signal collecting apparatus, periodic signal transmitting apparatus and signal collecting system

摘要

Disclosed is a signal collecting apparatus (200) that performs wireless communication with a periodic signal transmitting apparatus to which a predetermined period including a period for transmission and reception of a periodic signal that is periodically generated and a period for transmission and reception of a non-periodic signal that is non-periodically generated is repeatedly allocated. The signal collecting apparatus includes: a receiving unit (203) that receives the periodic signal from the periodic signal transmitting apparatus in the period for transmission and reception of the periodic signal; and a transmitting unit (201) that transmits, when the non-periodic signal is transmitted to the periodic signal transmitting apparatus, time point information to the periodic signal transmitting apparatus to which the periodic signal is transmitted. A point of time indicated by the time point information is present within a range of the period for transmission and reception of the non-periodic signal.
