Description

  The present invention relates to an elevator apparatus that can be operated by a remote controller.

  There is an elevator device that can call a car and open and close a door with a remote controller (Patent Document 1).

  In Patent Document 1, there is no description as to why signal transmission between the remote controller and the receiver is performed, but signal transmission is generally performed by infrared rays or radio waves.

  When using infrared rays, the remote controller must send an optical signal to the receiver.However, when installing an elevator in a general household, there are many restrictions on the installation location, so the remote controller must be installed only in front of the platform. It may not be usable. This is preferable in terms of safety, but is not convenient as a remote controller intended to be used in an elevator.

  When radio waves are used, even if there is a wall between the remote controller and the receiver, a signal can be sent to the receiver if the signal attenuation by the wall is not so great. Therefore, it is preferable in terms of convenience, but this point may be a problem.

  For example, in a general home, when a call is made with a remote controller in the own room, the elevator moves to the floor and opens the door. At this time, if the calling person is still in his / her room and there are children or infants near the platform, an unexpected accident may occur.

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide an elevator apparatus that can enjoy the goodness of both the infrared type and the radio type with respect to the remote operation by the remote controller and also considers safety. .

An elevator apparatus according to the present invention includes a lifting / lowering means for raising / lowering a car, a door opening / closing means for getting on / off the car, a control circuit for controlling operations of the lifting / lowering means and the opening / closing means, and a remote controller for remote operation And a receiver that receives a signal output from a remote controller and transmits the signal to the control circuit, wherein the remote controller transmits a signal corresponding to the operated content of infrared rays and radio waves. The receiver is capable of receiving both infrared and radio waves, and the control circuit regulates the operation of the door opening and closing means when receiving a signal from the remote controller only with the radio waves. , or receive from the remote controller signals from the remote controller from the time accepted by the infrared within a predetermined time The and when the received radio waves only to release the restriction, the control circuit, radio signals from the remote controller from the time when the landing call devices or destination floor indication device of said cage has been operated within a predetermined time It is characterized in that the restriction is released when it is received only .

  Since the car can be called by radio waves, it is convenient, and in the case of calls by radio waves, the door is opened and closed, so that safety is increased. In addition, even though the regulation is being performed, when the signal from the remote controller is received only by the radio wave within a predetermined time from the time when the signal from the remote controller is received by the infrared ray, the radio wave is used to cancel the regulation. Convenience is not impaired.

It is a block diagram of an example of an embodiment of the invention. It is a flowchart which shows an example of the regulation about door opening and closing same as the above. It is a flowchart which shows an example about the restriction | limiting about the door opening and closing same as the above, and its cancellation | release.

Elevator apparatus of the present invention, a lifting hand stage for elevating the cage 1, and closing the hand stage of the door for passenger to the car 1, a control circuit 5 for controlling the operation of the lifting hand Dan及 beauty the open hand stage , A remote controller 6 for remote operation, and a receiver 7 that receives a signal output from the remote controller 6 and transmits the signal to the control circuit 5.

The remote controller 6 sends out a signal corresponding to the operated content by both infrared rays and radio waves, the receiver 7 is capable of receiving both infrared rays and radio waves, and the control circuit 5 receives from the remote controller 6. It regulates the operation of opening and closing the hand stage door when receiving a signal radio waves only.

  The control circuit 5 cancels the restriction when it receives the signal from the remote controller 6 only by radio waves within a predetermined time from the time when the signal from the remote controller 6 is received by infrared rays.

  The control circuit 5 also receives the signal from the remote controller 6 only by radio waves within a predetermined time from when the landing calling device 45 or the destination floor indicating device 15 in the car 1 is operated. It is preferable that the regulation is released.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. In FIG. 1, reference numeral 1 denotes an elevator car, 2 denotes an elevating motor as elevating means, and 3 denotes an opening / closing motor for the door 13 of the car 1. The motors 2 and 3 are driven by commands from the control circuit 5, and the motor 2 is responsible for raising and lowering the car 1, and the motor 3 is responsible for opening and closing the door 13 and opening and closing the door 40 at the landing. The door 13 of the car 1 and the door 40 of the landing on the floor where the car 1 is located are mechanically linked.

  In the figure, 15 is a destination floor indicating device installed in the car 1, 45 is a car calling device installed at the landing, and these are also connected to the control circuit 5. Note that the calling device 45 provided at the landing is provided for each landing on each floor.

  When the landing device 45 on a certain floor is operated, the control circuit 5 moves the car 1 to that floor and then opens the door 13 and the landing door 40 on that floor by driving the motor 3 which is an opening / closing means. The doors 13 and 40 are closed after a predetermined time. When the passenger on the car 1 indicates the destination floor by the destination floor indicating device 15, the control circuit 5 raises and lowers the car 1 to the instructed destination floor, and then opens the door 13 and the landing door 40 on that floor. .

  The elevator apparatus can respond to the calling of the car 1 and the opening / closing operation of the doors 13 and 40 by the remote controller 6. Further, the remote controller 6 here sends out a signal corresponding to the operation content by both infrared transmission and radio transmission when the call button of the car 1 or the opening / closing buttons of the doors 13 and 40 are operated.

  Therefore, the destination floor indicating device 15 installed in the car 1 and the car calling device 45 installed at the landing can receive both the infrared signal and the radio signal from the remote controller 6. A receiver 7 is provided.

  However, in this elevator apparatus, when the receiver 7 receives both the infrared signal and the radio signal (or only the infrared signal) from the remote controller 6 and when the receiver 7 receives only the radio signal. The control circuit 5 performs different operations.

  That is, when the receiver 7 receives the calling signal from the remote controller 6 for both the infrared signal and the radio signal (or only the infrared signal), the control circuit 5 determines the destination in the calling device 45 or the car 1 at the landing. The same control as when the floor indicating device 15 is directly operated is performed. For this purpose, in response to a call by the remote controller 6, the car 1 is moved to that floor and the doors 13 and 40 are automatically opened after landing.

  However, if the receiver 7 receives the call signal from the remote controller 6 only with a radio signal (when no infrared signal is received), the control circuit 5 simply moves the car 1 to the called floor. To do. That is, as shown in FIG. 2, even if the car 1 reaches the floor, the operation of opening the doors 13 and 40 is not performed. The “remote control” in FIGS. 2 and 3 indicates the remote controller 6.

  The operation of opening the doors 13 and 40 is performed by the control circuit 5 when the receiver 7 receives the call signal of the car 1 from the remote controller 6 or the opening signal of the doors 13 and 40 by infrared rays. The opening operation may be performed when the car calling device 45 on the floor is directly operated.

  When the receiver 7 receives only the radio signal, it is assumed that the person who operated the remote controller 6 is not near the landing, and the opening operation of the doors 13 and 40 is refrained, and there is a person who operates near the landing. When it becomes clear, the doors 13 and 40 are opened.

  In order to realize such a difference in operation, different signals are sent to the control circuit 5 when an infrared signal is received here and when only a radio wave signal is received. For example, when an infrared signal is received, a flag indicating that the signal is received by infrared rays is set as a signal sent to the control circuit 5.

  The opening buttons of the doors 13 and 40 included in the remote controller 6 are operated when it is desired to open and extend because the doors 13 and 40 cannot be entered before the doors 13 and 40 are automatically closed. The close button is operated when it is desired to close the doors 13 and 40 quickly after entering the car 1.

  Even when the open button or the close button included in the remote controller 6 is operated, the control circuit 5 performs different control depending on whether the receiver 7 receives the open signal with infrared rays or only with radio waves.

  That is, when the receiver 7 receives an open / close signal by infrared rays, the control circuit 5 performs an operation corresponding to the signal. However, when receiving only by radio waves, the control circuit 5 does not perform the opening and closing operations of the doors 13 and 40, and does not perform the voice or the operation so that the user operates the remote controller 6 toward the receiver 7. Notification using a display.

  However, it may be difficult for a wheelchair user or a caregiver to point the remote controller 6 toward the receiver 7 in the car 1 within the narrow car 1. In addition, since the user has a baggage, it may be difficult to point the remote controller 6 toward the receiver 7 in the car 1. In such a case, it is preferable that the control circuit 5 causes the doors 13 and 40 to open and close according to the radio signal from the remote controller 6.

  For this reason, in the elevator apparatus shown here, if the previous operation is performed by receiving an infrared signal, and if the radio signal is received within a predetermined time from the reception of the infrared signal for the previous operation, It is assumed that the control circuit 5 performs the next operation according to the signal. FIG. 3 shows a flow for this operation.

  In addition, even if the immediately preceding operation is performed by directly operating the car calling device 45 at the landing or the destination floor indicating device 15 in the car 1, the same operation as that at the time of receiving the infrared signal is performed. Yes.

  If it is a radio wave signal, the receiver 7 can receive the signal even when the remote controller 6 cannot be directed to the receiver 7, so that the convenience of using radio waves in addition to infrared rays is maintained. Can do. In addition, since the operation using the radio signal imposes restrictions on the opening and closing of the doors 13 and 40 rather than the operation using infrared rays, the safety can be kept high.
