Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a remote control device for an elevator.

When loading and unloading cargo using a forklift in a cargo elevator, work efficiency is extremely poor if the forklift has to be lowered each time to call the landing, operate the transport button, etc. For this reason, a transmitter of a wireless communication device is installed on a forklift, a receiving device is installed at each floor landing, and the elevator is used while remaining on the forklift.

However, with this type of wireless communication device that uses radio waves, interference and malfunctions occur due to radio waves from the transmitting devices on the upper and lower floors and on different cars, making it impossible to operate the elevator accurately. If your luggage is sent to the outside floor, there is a risk that the door may close while you are loading or unloading your luggage.

In order to prevent malfunctions caused by this type of interference, wireless communication devices with strict interference prevention measures have been commercially available, but they are extremely expensive, require the same number of units as floors, and are expensive when it comes to transmitting devices. This could not be applied to elevators that require the same number of forklifts.

There are also photoelectric devices that use light rather than radio waves as wireless communication devices. This means that the directivity of the light emitted from the floodlight is relatively narrow, and there is less of a problem of interference like with radio waves, but when operating an elevator, it is necessary to always stop the forklift accurately at a predetermined position. However, if the directivity of the projector was made too wide to reduce this drawback, the optical signal would reach the receiver of another machine installed in parallel, causing the elevator to malfunction.

This invention solves the above-mentioned conventional drawbacks.The elevator operation signal sent from the wireless communication device is displayed on the display device, and after the operator confirms the contents, if the contents are correct, an acceptance signal is sent. It is an object of the present invention to provide a remote control device for an elevator that can transmit only accurate elevator operation signals to the elevator even if there is a malfunction such as interference by sending a cancellation signal.

Hereinafter, a concrete example of this invention will be described based on FIGS. 1 to 5.

Next, the operation of the elevator remote control device according to this embodiment configured as described above will be explained.

Assume that the basket is now on the first floor and the door is open. Here, since the car is on the first floor, the 1-dark output relay contact 20 of the car position detection device is closed, and since the door is open, the door fully closed confirmation relay contact 21 is closed. Also,
Since the car is stopped, the traveling relay contact 22 is closed.

In this state, when the cargo handler on the first floor presses the door close command button 1 of the transmitter 1A, the output relay contact 17 of the receiver 1B is activated.
is closed. When this contact 1T closes, (g) the power supply -
Contact 14 - Contact 20 - Contact 21 - Contact 17 - Memory relay 17A - (c) Door close command memory relay 17 in closed circuit of power supply
A is energized and its normally open contacts 17Aa to 17Ad are closed. When contact 17Aa closes, (-1-) is connected to source - contact 14 - contact 2 - contact 21 - contact 17Aa - memory relay 17A - ←) door close command memory relay 17 in the closed circuit of the power supply.
Since A is self-held, it is no longer necessary to release the door closing command button T. In addition, by closing the contact 17Ad (→Power source - Contact 17Ad - Lamp 13L - (c)
Due to the closed circuit of the power supply, the lamp 13L of the door closing signal lamp 13 of the received signal display device 1C lights up, indicating that the door closing command signal has been received.

After that, the cargo handler confirms that the cargo handling on the first floor has been completed, and presses the signal reception button 9 of the transmitter (iiiA), which closes the output relay contact 19 of the receiver 1B. (G) Power supply - Contact 14 - Contact 19 - Command relay 19
A-(c) A closed circuit of the power supply is formed, the signal reception command relay 19A is energized, and its normally open contacts 19Aa, 19
Close the Ab. When contact 19Aa is closed, command relay 19A is activated (4-)! Source-Contact 17Ab-Contact 19
Aa-Command L/-19A-←)1! self-maintained in a closed circuit at the source. Also, when contact 19Ab is closed, (g)
Power supply - contact 19Ab - contact 17Aa - output relay 17
B-@ is the closed circuit of the source and the door close command output relay 17 of this remote control device! is energized and sends a door closing command signal to a well-known elevator control circuit to begin closing the door. When door closing is completed and the door is fully closed, the door fully closed confirmation relay is energized by a well-known circuit, and its contact 21 is opened, so the door closing command memory relay ITA is deenergized, and its contacts 1γAa to 17Ad opens. When contact 17Ab opens, signal acceptance command relay 19A is deenergized, and its contacts 19Aa and 19Ab are opened. When contact 17Ac is opened, door close command output relay 17B is deenergized. Further, when the contact point 17Ad is opened, the lamp 13L of the door closing signal light 13 is turned off.

In addition, in the above case, if the output relay contact 17 of the receiving device JilB is closed due to interference due to signals from other floors or parallel machines rather than a button operation by the cargo handler, the door closing command is issued in the same manner as described above. The memory relay 17A is energized, and the door close command signal lamp 13 of the reception signal display device is turned on.

However, as described above, there is no danger that the door will immediately start closing just by turning on the signal light 13 and the door will collide with the cargo handler. If the cargo handler looks at the indicator light and notices that an unintended signal is being received, he can press the cancel button 8 on one of the transmitters to open the output relay contact 14 on the receiver IB and close the door. Command memory relay 17A is deenergized and its contacts 17
a to 17d are opened and the lamp 13L of the door close command signal lamp 13 of the reception signal display device IC is turned off.

The same procedure is also performed for elevator operations for call commands and destination commands for the second and third floors.

As explained above, this invention uses a display device for the received signal, cancels the signal transmitted wirelessly, adds an acceptance command signal, and receives the elevator operation signal in an elevator equipped with means for transmitting the elevator operation signal wirelessly. Then,
First, the type of signal is displayed on the display device, and if the cargo handler confirms the display and there is an error in the transmitted signal, he cancels it (by issuing No. 8, he cancels the displayed signal, and if it is correct, he issues an acceptance command. By emitting a signal, the elevator operation signal is controlled to be transmitted to the elevator control circuit, so even if the receiving device sends out a wrong signal due to malfunction such as interference, this can be canceled and the correct signal is always sent. Because the elevator operation signal can be transmitted to the elevator control circuit,
This eliminates the need for expensive wireless communication equipment with strict anti-interference measures, prevents erroneous operations by the cargo handler, and also allows the cargo handler to clearly determine which operation commands are being received to cause the elevator to operate. . Furthermore, since the elevator can be operated safely and reliably while riding on the forklift, there is an advantage that work efficiency can be improved.
