Abstract: An excrement management system according to an embodiment includes: a closet bowl in which a bowl part for receiving excrement is formed; a light emitting unit configured to emit light toward an inner part of the closet bowl; a light receiving unit comprising an image sensor configured to receive light; a cloud server and an edge server configured to analyze light reception data received by the light receiving unit; a first communication device configured to transmit the light reception data to the cloud server; and a second communication device configured to transmit the light reception data to the edge server. The cloud server analyzes the light reception data to determine a characteristic of excrement, and the edge server analyzes the light reception data to determine whether to transmit the light reception data to the cloud server by the first communication device.
