The invention discloses automatic hatching egg embryo vital sign recognizing equipment and method. The equipment comprises a conveying device. The conveying device comprises two conveyor belts operating synchronously. The automatic hatching egg embryo vital sign recognizing equipment further comprises a spectral signal detecting device which comprises a bottom plate, a top plate and two side plates connected between the bottom plate and the top plate. The conveyor belts penetrate through a channel formed by the bottom plate, the top plate and the two side plates in an enclosure mode. A light source is arranged on the upper surface of the bottom plate. A photoelectric sensor is arranged at the position, symmetrical to a light source in a mirror mode, of the lower surface of the top plate. A mainboard is fixed to the top plate and provided with a spectral signal collecting and processing circuit and a data processor. The automatic hatching egg embryo vital sign recognizing equipment is reliable in detection result, high in precision and high in detection efficiency by the adoption of automatic control.
