The present invention relates to an elevator, and more particularly, to an elevator door automatic opening and closing device for detecting whether an occupant is located within a predetermined distance outside an elevator door, thereby allowing the elevator to stop and open and close the door automatically.

In general, the control means of the elevator is the first car switch manual conception method, which is the simplest operator operation method, mainly used for AC 1 speed.

There is also a second car switch automatic concept, which is a medium-speed, elevator with a driver and is the simplest.

And third, there is a single automatic manual closing system, which is the simplest automatic elevator.

The fourth is a single automatic electric closing method, which is a driving system with the third method slightly advanced, and is mainly used for AC two-speed.

Fifth, the Car Switch Selective Collective Dual method, which is a driver during the day, operates as a car switch, and is used automatically without a driver at night or during busy days, and is mainly used for small and medium-sized buildings.

The sixth is the selective collective dual method, which is a multi-purpose elevator with the function of selecting passengers and is a fully automatic elevator that drives passengers without a driver.It is suitable for small and medium buildings, hospitals, and apartments that can be driven by a driver when crowded. It is not so crowded that it is used only when it is uneconomical to have a driver.

The seventh is the Toka Selective Collective Dual system, which operates the two parallel elevators reasonably without a driver or a waste, and performs a Selective Collective Operation.

Eighth is the group control system, which provides the most efficient coordination of passenger services with more than three fully automatic driving operations.

In a conventional elevator capable of performing various types of driving as described above, in general, when there are many occupants, it is necessary to press the open button inside or outside the elevator until the occupants are all occupied or to keep touching the doors by hand. If the number of passengers is small, it is tedious to wait for the time until the door closes automatically, so the artificially closed button is pressed to close the door, which consumes more energy than if the door closes automatically. Here, the door of the elevator is opened and closed by a hatch door operator (hatch door operator), the hatch door operator is a device that is installed in the doorway of each floor with the hatch door to open the hatch door (call), Once registered, the door closes automatically and the interlock switch is activated to start the car. This is done by receiving a close signal from the control system when the car must answer the call or after a certain time has elapsed since the door was opened.

In addition, the car and the hatch door are closed at the same time, the interlock mechanically locks the hatch door, and the electrical contact allows the car to start in response to the call.

The interlock is attached to the hatch door operator on each floor and prevents the car from leaving without the door closed, prevents the door from opening in the platform before the car is completely grounded, and the electrical contact attached to the car is It acts to prevent the car from starting before closing. If the door is opened, a safety switch is installed to stop the car.

However, in the door opening and closing means of the elevator as described above, it is very inconvenient to use the elevator because the occupant must open and close the door by pressing the open button or the close button.

The present invention is to solve such a conventional drawback, the sensor to detect the situation outside the elevator door to open the door automatically when the occupant is waiting for the occupant, or if the occupant is missing or all the door will automatically close It is an object of the present invention to provide an automatic door opening and closing device of an elevator.

In order to achieve the above object, the present invention provides a passenger detection means installed on the upper side of the door to detect the presence of a passenger, a control means for receiving a result detected by the detection means and outputting a corresponding output level; A switching means switched according to the output of the control means, time adjusting means connected to the switching means to maintain a predetermined time in the open state, and an elevator door driving connected to the output side of the switching means to drive the door of the elevator. It comprises a means comprising a means.

Hereinafter, with reference to the accompanying drawings an embodiment of the elevator door automatic opening and closing device in detail as follows.

2 is a circuit configuration diagram according to the present invention, the sensor 10 is installed on the upper side of the door to detect the presence of the occupant sensor 10 and the output level corresponding to the result detected by the sensor 10 received The microcomputer 20 which is a control means for discharging the light, the transistor Q which is a switching means 30 which is switched according to the output of the microcomputer 20, and the transistor Q are connected for a predetermined time in a state where the door is opened. It is configured to include an elevator door driving means 50 which is connected to the output side of the condenser C, which is a time adjusting means 40, to drive the door of the elevator.

The present invention configured as described above, the occupant detection sensor 10 is installed on the outside of the elevator door to detect the presence of the occupant within a certain distance, if there is a passenger in the open state of the door if the occupant in the sensor 10 by detecting the microcomputer The microcomputer 20 notifies the occupant of the occupant 20, and the microcomputer 20 controls the transistor Q to be turned off by outputting a low level to the transistor Q as the switching means.

Therefore, when the transistor Q is turned off, the transformer T does not operate, and thus the motor M, which is the elevator door driving means 50, does not drive, and thus the door remains open.

Then, when the occupants are all boarded inside the elevator, the sensor 10 detects that there is no more boarding within a certain distance outside the door, and informs the microcomputer 20 that there is no occupant, and the microcomputer 20 recognizes this. Will output the corresponding signal high level.

Therefore, the transistor Q receiving the high level is turned on. At this time, the charge of the power supply Vcc is charged to the capacitor C, which is a time adjusting means, for a predetermined time, and then the transformer T is sent to the primary side of the transformer T. Let it work This is to ensure that the door is safely closed by keeping the door open for a certain time even after no one is going to board the elevator from the outside while the door is open.

If the occupants are all in the elevator, when the elevator is raised or lowered on the floor where no one is going to board, the elevator 10 does not stop by the detection of the sensor 10 and the person who is going to board or gets off Only when there is a door will be opened by the control of the microcomputer 20.

As described above, the present invention determines whether the elevator stops and opens or closes the door according to the presence or absence of an occupant who intends to use the elevator. At this time, if there is no occupant, the vehicle passes through the floor to prevent unnecessary stops and the door when the elevator stops. By opening and closing the to maintain the standby state until the power of the occupant, as well as to promote the convenience and safety of the elevator user, there is an effect that can save energy in operation.
