Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in an elevator control device for preventing an elevator canning accident.

[0002]

[Prior art]

 The elevator has a car call button inside the car and a hall call button at the hall. Then, the user operates the hall call button to call the car, and when the door opens, the passenger gets into the car and operates the car call button on the destination floor in the car, that is, the destination floor to register. On the other hand, the door automatically closes, travels toward the registered car call, and when the car arrives at that floor, the door automatically opens and closes after a certain time to the next registered car call or landing. Service for the call. Then, at this time, if no call is registered, the door is kept closed and waits on that floor, or after a predetermined time departs toward the reference floor and closes the door on the reference floor. It is controlled to wait as it is. With regard to the present technology, the car operation control is described in, for example, JP-A-61-206570, the standard floor restoration is JP-A-61-142768, and the structure of the in-car operation panel is actual. JP-A-58-20260 is cited.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional technology, the user misunderstood that he was still on the floor where he / she got in, even though the car had already thought or wasted and the car has already arrived at the destination floor of the user. , You may press the car call button on the destination floor again. However, in the conventional door control device, under such a condition, the door cannot be opened unless the door is opened. Therefore, if the user does not know this, the door will not open, so the user will push the car call button on the other floor to call the car to the other floor and then push the destination floor again. Also, if this operation is not performed, a canning accident may occur.

The present invention has been made in view of the above drawbacks, and an object of the present invention is to provide an elevator door control device capable of easily opening a car.

[0005]

[Means for Solving the Problems]

 The purpose is to register a car call or a landing call, a car for an elevator that serves a plurality of floors according to the call, and a control means that controls the opening and closing of a door when the car reaches a floor that has served. In the elevator door control device including the above, it is achieved by including a command means for issuing a command to open the door when the car call button on the floor where the car is stopped is operated.

[0006]

[Action]

 According to the present invention, when the user is dim and arrives at the destination floor but does not notice it, the user thinks that he has forgotten to press the car call button on the destination floor, and again. , Press the basket call on the destination floor. As a result, the door opens, so that the user notices that he misunderstood and can easily get off the floor from the car. Also, canned accidents can be prevented.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The elevator shall service the 1st to 3rd floors.

FIG. 2 shows a front view of the operation panel in the car. In the figure, 1B to 3B are car call buttons that register the destination floor of the car, CB is a close button that gives a door close command, OB is an open button that gives a door open command, and LU is lit while the car is rising. The indicator light, and likewise, the LD is an indicator light that lights up while the car is descending.

FIG. 1 is an electrical connection diagram of the door control device of the present invention. In the figure, P and N are positive and negative DC power supply terminals, 1Ba to 3Ba are normally open contacts of the car call buttons 1B to 3B, and 1C to 3C are relays that are activated when the car call buttons 1B to 3B are operated. 1Ca to 3Ca are normally open contacts, and 1Pb to 3Pb are energized when the car stops on the first to third floors. Normally closed contacts of a relay not shown, similarly 1Pa to 3Pa are normally open contacts, 1D to 3D. Is a diode inserted in series with contacts 1Ba to 3Ba, AX is a door opening assist relay that is activated only when the car call button on the same floor as the car is operated, AXa is its normally open contact, and DO is the door. A door opening relay that gives an opening command to DOa, DOa is its normally open contact, 1DZb to 3DZb are the first to third floors of the door zone, OBa is the contact point of the open button OB, and DSa is the command to open the door when the car is on the floor. Not shown Normally open contacts, OLSB the normally closed contact to open the open end of the door, DCb is a normally closed contact of the relay of the door close command (not shown).

Next, the operation of this embodiment will be described.

Now, consider a case where the user goes from the first floor to the third floor. The passenger operates a landing call button on the first floor (not shown), and when the car arrives on the first floor and the door opens, the passenger gets into the car. Then, push the car call button 3B on the third floor. By closing the contact 3Ba, a circuit of P-3Ba-3D-3Pb-3C-N is formed, the relay 3C is energized, and the contact 3Ca self-holds. At this time, since the contact 3Pa is open, the relay AX is irrelevant. Therefore, the car runs toward the third floor by an operation control device (not shown) and stops. At this time, the contact DSa is closed, the relay DO is energized by the circuit of P-DSa-3DZb-DCb-OLSb-DO-N, and the relay DO is self-held via the contact DOa, and the door starts to open by the door driving device (not shown). , When the door is fully opened, the contact OLSb is opened, the relay DO is deenergized, and the door is stopped. There, passengers can get off at the landing on the third floor. On the other hand, the contact 3Pb is opened, the relay 3C is deenergized, and the door is closed by the door control device (not shown) to service the next call. If there is no call, it will wait on the 3rd floor.

Next, when the above-mentioned customer arrived on the 3rd floor and opened the door, he did not dimly get off, so the door automatically closed, and if there was no call at this time, The car will stop on the 3rd floor. After a while, the customer thinks he did not press a certain car call button, for example, the car call button on the 3rd floor, or when he sees the indicator on the destination floor and finds that the car is arriving on the 3rd floor. , Involuntarily pressing the car call button 3B on the third floor. Then, the contact 3Ba is closed, the relay AX is energized by the circuit P-3Ba-3Pa-AX-N, the contact AXa is closed, and the relay AX is relayed by the circuit P-AXa-3DZb-DCb-OLSb-DO-N. DO is energized and the doors are opened in the same manner as above, allowing passengers to drop off at the desired third floor landing. Even if the customer presses the open button OB, the contact OBa is closed, the relay DO is activated in the same manner as above, and the door can be opened.

As described above, according to the present embodiment, when the passenger in the car is in the standby state, even if the car on the stop floor is not known to operate the open button to open the door. The door can be opened by operating the call button, preventing canning accidents.

[0014]

[Effect of device]

 According to the present invention, since the customer in the car operates the car call button on the same floor as the stop floor of the car, the door can be opened without pressing the open button. Even if the car is locked in the basket, the door can be opened by pressing the basket call button, which has the effect of preventing canning accidents.
