In one embodiment of the invention, the first height may be equal to 1.1, 1.2 or 1.3 meters, the second height may be equal to 0.4, 0.5 or 0.6 meters, and the third height may be equal to 1.5, 1.6 or 1.7 meters.
In one embodiment of the present invention, when the determination device determines that a child has entered the car alone, the microphone emits a voice prompting an adult in the car to press the prompt key, for example, a prompt voice "whether an adult is in the car, if there is a request to press the prompt key" is emitted.
In one embodiment of the invention, the judgment device judges that a child takes the elevator alone if the prompt key is not triggered all the time within a preset time (for example, 1-5 seconds) after the microphone sends out the prompt voice.
In one embodiment of the invention the elevator car control system further comprises a weighing device. A weighing device is mounted on the car for measuring the load in the car. When the judging device judges that a child enters the car alone or the load measured by the weighing device is smaller than the preset mass, the judging device judges that the child takes the elevator alone. Thus, the accuracy of the judgment can be improved.
In an embodiment of the present invention, the predetermined mass may be within a range of 10 to 30 Kg. For example, the aforementioned predetermined mass may be equal to 10Kg, 20Kg or 30 Kg.

In one embodiment of the invention the elevator car control system further comprises an alarm device. The alarm device is used for giving an alarm to a remote administrator when the judgment device judges that the child takes the elevator alone. The remote administrator remotely confirms whether an adult is in the car after receiving the alarm, for example, whether an adult is in the car through remote video. If the presence of an adult in the car is remotely confirmed, the door of the car is remotely controlled to be closed so as to allow the elevator to continue to operate normally.
In one embodiment of the invention, when the judging device judges that a child enters the car alone, the prompt key displays a first color; when the judging device judges that a child takes the elevator alone, the prompt key displays a second color different from the first color. For example, the first color may be bright red and the second color may be yellow.
In one embodiment of the invention, the first detector comprises a first light detector comprising a first light emitter mounted on one side of the car door and a first light receiver mounted on the other side of the car door.
In one embodiment of the invention, the second detector comprises a second light detector comprising a second light emitter mounted on one side of the car door and a second light receiver mounted on the other side of the car door.
In one embodiment of the invention, the first light detector and the second light detector are two light detectors of an infrared light curtain of the car located at a first height and a second height, respectively.
