The invention discloses an elevator infant protection system and a working method thereof. The protection system comprises a light curtain system, an elevator weighing device, an operation box and an elevator operation safety control system. The light curtain system comprises a plurality of light curtain assemblies evenly distributed in the height direction of a car door of an elevator, wherein all the light curtain assemblies are connected with a shielding detector; an output signal of the shielding detector is connected with a judgment circuit; and the elevator weighing device, the operation box and the elevator operation safety control system are all connected with the light curtain system. According to the working method, when passengers enter and go out of the elevator, the light curtain assemblies scan the passengers and conduct processing and comparison to judge passenger conditions in the elevator; if there are adults in the elevator, the elevator operates normally; and if there are only infants in the elevator, an infant protection program is started, a landing door and the car door are kept in an open state, the elevator stops running up and down temporarily, and a traction machine brakes. The elevator infant protection system and the working method thereof have the characteristics of accurately distinguishing and detecting the infants and improving the protection performance for the infants.
