Claim 13:
14. The traffic line tracing apparatus according to claim 11 further includes:
living organism signal collector including at least one of a thermal imaging camera configured to determine whether the self-quarantining target person is present in a given space by observing an image change in a thermal image, an image sensor for knowing presence or absence of movement of the self-quarantining target person by checking an image variation, an infrared human body detection sensor that detects presence or absence of the self-quarantining target person and a microphone configured to detect breathing sound or living sound of the self-quarantining target person;
an energy fluctuation curve calculator configured to calculate a time-dependent energy fluctuation from a signal obtained from the living organism signal collector; and
a self-quarantining target person dormancy checker configured to determine that the self-quarantining target person is in a dormant state either when it is determined by the communication connection verifier that the mobile device of the self-quarantining target person is not in the residence or when the energy fluctuation continues at a reference value or less for a predetermined time period or more.
