Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a maintenance operation device for an elevator.

[0002]

2. Description of the Related Art In general, as maintenance work carried out by a maintenance worker on a car at the time of maintenance, the operator operates an operating device permanently installed on the car to move the car up and down to inspect around floor doors. Work, inspection of the instrument box, operation of the switch provided in the instrument box when a door trouble occurs, replacement of the ROM in the instrument box, etc., measure the frontage of the door machine, and write the frontage dimensions in the ROM, etc. There is.

As an example of this frontage writing operation, the door is opened and closed twice by the close button provided on the instrument box, and then the stop switch is cut off, the door of the instrument box is opened, and the switch provided in the ROM is opened. Turn on, 4 ~
The switch was turned off after 5 seconds. As an example in which an operating device for moving the car up and down is provided, the one described in JP-A-3-46985 can be mentioned. Further, in order to eliminate the operation switches from the operation panel in the car, the one described in Japanese Patent Application Laid-Open No. 2000-26382 can be mentioned as one that enables the car to be driven by the portable terminal device.

[0004]

In the above-mentioned prior art, there is a problem in that an operating device for moving the car up and down is required for each car, which is very expensive. Further, in order to write the frontage dimension, a large number of switches are required in the instrument box, and since the switches are provided on the front surface of the instrument box, the operation work is not easy. Further, the latter proposed one relates to driving in a car and cannot be applied to driving on a car.

It is an object of the present invention to provide an elevator maintenance operation device which can eliminate the need for an operating device which is permanently installed on a car and can significantly eliminate the switches provided in the equipment box. It is in.

[0006]

[Means for Solving the Problems] The above object is an elevator equipped with a car and an equipment box for controlling a door provided on the car above the car. A connection terminal to which a connector provided in a portable terminal device to be carried is provided, and at the time of maintenance, a maintenance person rides on the car to connect the connector of the portable terminal device and the connection terminal of the instrument box, This is achieved by operating the mobile terminal device to perform maintenance work.

In this way, the portable terminal device carried by the maintenance staff can be connected to the connection terminals provided on the equipment box, and the portable terminal can be operated to perform the raising / lowering operation of the car during maintenance. In addition, if the mobile terminal device is equipped with the operating functions of the switches provided on the instrument box,
The switches may be eliminated.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram showing a maintenance operation device for an elevator according to an embodiment of the present invention, and FIG. 2 is an enlarged view showing the relationship between the equipment box of FIG. 1 and a portable terminal device.

In the figure, 1 is a car, and a door 2 is provided in the car 1. 3 is a main rope whose one end is connected to the car 1 of the previous term and the other end is connected to a counterweight (not shown). This main rope 3 is a sheave (not shown)
The car 1 is driven up and down by the drive. Reference numeral 4 denotes a motor for driving the door 2, which is provided on the car 1. An instrument box 5 is provided on the car 1. The instrument box 5 is provided with a connection terminal 6, and the connection terminal 6 is connected to a microcomputer via an input / output interface circuit (not shown). Reference numeral 7 denotes a mobile terminal device carried by a maintenance person. The mobile terminal device 7 has not only a function of raising and lowering the car 1 but also functions of switches provided in the equipment box, and the cable 8 , And is connected to the connection terminal 6 via the connector 9.

Now, in order for the maintenance staff to get on the car 1 and raise and lower the car 1, the connector 9 of the portable terminal device 7 is connected to the connection terminal 6 and the portable terminal device 7 is operated. It can be carried out. In this way, since the operation can be performed by the mobile terminal device 7, it is possible to eliminate the operating device required for each car.

Further, in the case of the work for writing the frontage size in the ROM in the equipment box 5, the maintenance person who is on the car 1 connects the connector 9 of the mobile terminal device 7 to the connection terminal 6 as described above, and the mobile terminal When the device 7 is started, the door frontage measurement item on the screen is selected and the start button (not shown) is clicked, the frontage operation is automatically started, and the car
By opening and closing, data is written to the microcomputer in the equipment box. In this way, the mobile terminal device 7
Since the switches provided on the instrument box 5 up to now can be operated by the operation of
It is possible to eliminate the switches provided on the. Also,
Since the operation is automatically performed, a malfunction or the like does not occur, and the work can be performed quickly.

[0013]

According to the present invention, it is possible to dispense with the operating device that is permanently installed on the car. Further, it is also possible to provide a maintenance operation device for an elevator that can significantly eliminate the switch provided in the equipment box.
