The invention discloses a control device for preventing children from taking an elevator alone. The control device comprises a control circuit and two human body heat-sensing detectors connected with the control circuit, wherein the two human body heat-sensing detectors are installed on the inner side of an elevator door, and the detection ranges of the two human body heat-sensing detectors are not mutually overlapped in a vertical direction; and the two human body heat-sensing detectors are connected to the control circuit through conducting wires. When a child enters the elevator, only the human body heat-sensing detector installed in a lower position detects a human body to send a signal, the control circuit controls the elevator door not to be closed at once and then controls the elevator to stop running. When an adult enters the elevator, both the two human body heat-sensing detectors detect the human body to send a signal, and the control circuit controls the elevator to normally run. The control device for preventing children from taking the elevator alone adopts the two human body heat-sensing detectors to effectively prevent the child from taking the elevator alone and ensure the living safety of people, and the control device has the advantages of convenience in installation, sensitivity in control and the like.
Description
technical field [0001] The invention relates to a control device, in particular to a control device for preventing children from riding an elevator alone. Background technique [0002] Elevators play an important role in people's daily life, but if a child is not accompanied by an adult and takes the elevator alone, it will be dangerous. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies in the background technology and provide a control device that prevents children from taking an elevator alone. This control device uses a human body thermal detector to effectively prevent children from taking an elevator alone. [0004] In order to solve the above problems, the present invention takes the following technical solutions: [0005] A control device for preventing children from taking an elevator alone in the present invention comprises a control circuit and two human body heat detectors connected with the con...
