1 and 2, a preferred embodiment of the present invention will be described in more detail.

1 is a block diagram schematically showing the configuration of an infant monitoring system according to a preferred embodiment of the present invention.

Referring to FIG. 1, the infant monitoring system 100 according to the present invention includes an infant condition detecting apparatus 10 and an image display device 20.

The infant condition detecting apparatus 10 includes a voice frequency filter 12, a controller 14, a camera 16, and a transmitter 18.

The voice frequency filter 12 filters the voice signal corresponding to the crying sound frequency band of the infant, and generates an interrupt signal when the voice signal corresponding to the frequency band is input and transmits the interrupt signal to the controller 14. do.

Typically, the range of voice frequencies a human can hear is from 20 kHz to 20,000 kHz, the average human voice being less than 1,000 kHz, of which the voice of an adult male is approximately 400 kHz. On the other hand, the crying frequency of infants is about 1,000 Hz or more. Therefore, when the voice frequency filter 12 filters voice frequencies of 1,000 kHz or more, the crying sound of the infant may be detected.

When the interrupt signal is generated from the voice frequency filter 12, the camera 16 captures the current state of the infant in response to a predetermined control signal input from the controller 14, and outputs the image of the infant to the controller. Output to (14).

The transmitter 18 transmits the interrupt signal and the infant image to the image display device 20 in response to a predetermined control signal input from the controller 14.
