(2) The movement adopted by the device makes innovative improvement on the limit switch, the current limit switch commonly used for the swing gate is a photoelectric limit switch, when the swing arm swings, the movement of the swing shaft drives the light blocking sheet to move, and when the light blocking sheet shields the light source of the limit switch, the motor rotates reversely, so that the swing arm stops moving. If the photosensitive device has a problem, the limit switch cannot work normally. Therefore, the limit switch designed by the device is added with an electromagnetic induction device on the basis of the existing limit switch. When the electromagnetic induction piece moves to the middle gap of the limit switch, the limit switch generates magnetic attraction force to the limit electromagnetic induction piece, and the force gradually rises, so that the swing gate is decelerated in the swing process, when the electromagnetic induction piece moves to the middle position of the limit switch and limited opening or closing position, the magnetic attraction force reaches the maximum value, the rotating shaft is forced to stop rotating, and the swing speed is slowly slowed down when the swing gate is closed or the limit position is about to be reached in the starting process.

When the infant bumps the pendulum gate, the pendulum gate can bump along with and open certain angle, and the spring can reduce the speed of pendulum gate when opening, avoids pendulum gate to open the in-process speed of certain angle too fast, causes the injury of tumbleing on the inertia to the infant. When the swing gate is opened by a certain angle, the swing gate is fixed at the opened angle by the attractive force generated by the electromagnetic induction adsorption devices at the four top angles of the buffer device through the magnetic field generated by the electrified solenoid in the base, so that the damage to the infant caused by the rebound of the gate body is avoided. When the door body is reset, the swing gate is reset slowly in a mode that the electromagnetic induction force is reduced gradually.
The application has the beneficial effects that:
1. according to the application, the defects of the existing infant intercepting device are overcome from the viewpoint of personal safety of the infant, the intelligent infant intercepting function is realized through the combination of the intercepting door and the infrared array sensor, whether the infant is independently close to the elevator is judged from the fact that whether a moving human body exists in the two perception height ranges of the set infrared array sensor, the infant is judged from the most objective distinction between the infant and other passengers, and the infant intercepting success rate is increased.
2. The class of the interception door selects a swing gate, and the reaction mechanism is fast, so that interception failure caused by untimely closing of the interception door is avoided. And a buffer function and a reset device based on electromagnetic induction are added on the anti-collision device. When the infant bumps the interception door, the interception door can open certain angle along with infant's collision, and buffer spring plays the effect of buffering, prevents that the interception door from being bumped when, opens too soon and produces the injury to the infant, also reduces the collision and causes mechanical damage to the pendulum gate simultaneously. The reset device based on electromagnetic induction avoids the damage to the infant caused by the quick rebound reset of the swing gate, but controls the slow reset of the swing gate under the condition of no obstacle through the attractive force of the magnetic field to the electromagnetic induction adsorption device.
3. The limit switch is combined with an electromagnetic induction technology on the basis of the prior art, a light blocking induction device and an electromagnetic induction device are arranged in the middle of a gap of the limit switch for opening and closing the door, and when a light source is shielded, the motor is reversed. In order to avoid error in light blocking induction, the motor cannot be reversed in time, the opening and closing angle exceeds the threshold value, damage is caused to the swing gate and interception failure is caused, when the random core rotating shaft of the limit electromagnetic induction sheet rotates to reach the middle gap position of the opening and closing limit switch, the magnetic attraction of the electromagnetic induction device of the opening and closing limit switch and the limit electromagnetic induction sheet reaches the maximum value, and the rotation of the core rotating shaft is prevented to a certain extent.
4. The application adopts the technologies of face recognition, emotion recognition and face similarity comparison, and is convenient for guardianship and passersby to find lost infants in time according to the face image information of the display.
5. The intercepting device is fully-automatic intelligent control, does not need the help of manpower, prevents accidents, protects the safety of infants, greatly reduces the waste of manpower resources, and simultaneously ensures that the infants can take an escalator under the nursing of a guardian through delayed door opening.
