Personalized alarm provision system using biometric information and motion information on basis of doppler signal

A personalized alarm provision system using biometric information and motion information based on a Doppler signal, the system comprising a biometric signal and motion signal information acquisition device using the Doppler signal, a server, and a guardian terminal, wherein

• the biometric signal and motion signal information acquisition device using the Doppler signal includes:
• a Doppler signal acquisition unit for emitting a radar signal to a subject, acquiring a reflected and returned radar signal to acquire the Doppler signal, and processing the Doppler signal to acquire a first phase Doppler signal and a second phase Doppler signal;
• a Doppler signal processing unit for processing the first phase Doppler signal and the second phase Doppler signal to acquire first signal information and second signal information, respectively;
• and
• a signal information output unit for acquiring the first signal information and the second signal information, and analyzing the first signal information and the second signal information using a preset algorithm to acquire biometric signal information and motion signal information,
• wherein the server acquires life pattern information by statistically calculating a time of staying in each space of a household on the basis of the motion signal information and biometric signal information, and sets living spaces and danger spaces on the basis of the life pattern information.
