Description

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

As a conventional remote control device for this type of elevator, the first
There is one shown in Fig. 2. In tff1 figure iC,
1 is an elevator car, 2 is a passenger, 3 is a cart on which the passenger 20 is riding, 4 is a transmitter provided on the cart 3 for transmitting an optical signal, and 5 is a remote control light emitted from the transmitter 4. 6 is a signal processing circuit that processes the remote control optical signal received by the receiver 5; 1 is an elevator control device;

Climb call registration provided in the trolley 3 according to the will of the passenger 2,
When any of the operation switches (not shown) on the operation panel of the destination floor or the like is operated, the transmitter 4 transmits a corresponding signal as an optical signal. The receiver 5 converts the received optical signal from the transmitter 4 from optical to electrical state and provides it to the signal processing circuit 6, and the signal processing circuit 6 issues an operation command to the elevator control device 7 according to the provided electrical signal. give.

Thereby, the occupant 2 can perform operations such as registering a call to a location away from the elevator and registering a destination floor without getting off the trolley 3. However, since the optical signal from the transmitter 4 received by the receiver 5 attenuates as the distance between the transmitter 4 and the receiver 5 increases, there is a limit to the operating range that can be remotely controlled. This operating range does not always have a constant size (it varies depending on changes in temperature, power supply voltage, etc.).

For this reason, adjustments made during installation or maintenance may limit the operating range of remote control to, for example, 5 meters, where remote control is a problem. Until one day, remote control was possible from a distance of 5 meters, but from the next day it suddenly became possible to control the remote control from a distance of 5 meters.
However, even though this remote control device is in place, crew member 2 has to get off the trolley 3 one by one and operate the elevator's call registration operation panel to register the call. There was a fear that it would happen.

This invention has been made in view of the above-mentioned points, and an object of the present invention is to provide an elevator remote control device whose operating range does not fall below a predetermined size even when fluctuations in temperature or power supply voltage occur. do. The present invention will be explained below based on the drawings.

FIG. 3 is a block diagram of an elevator remote control device according to an embodiment of the present invention. In the same figure, the same reference numerals as in FIG. It consists of lamps and light emitting diodes that operate when the intensity exceeds the specified value. Here, the operation margin indicator 8's predetermined value of the remote control light signal is the lowest value that can be remotely controlled, the value plus the variation of the remote control light signal caused by temperature or power supply voltage fluctuations. do. That is, during installation or adjustment, the operating margin indicator 8 simply indicates that the transmitter 4 has a predetermined operating range.
Rather than adjusting the orientation and sensitivity of the receiver 5, the VC is adjusted so that the operating margin indicator 8 operates within a predetermined operating range and can be remotely controlled. The operating margin indicator 8 operates because the remote control light signal is being transmitted and received at a value equal to or greater than the minimum value that allows remote control plus the variation in the remote control light signal caused by temperature or voltage fluctuations. Therefore, even if the operating range of the remote control changes due to temperature or voltage fluctuations, the operating range will not become smaller than a predetermined width.

Therefore, the operating range becomes smaller than the predetermined size,
Despite the presence of this remote control device, there is no fear that the occupant 2 will get off the 1' trolley 3 and perform an elevator call registration operation.

Although the installation location of the operating margin indicator 8 is not specified in this embodiment, it may be provided inside the signal processing circuit 6 or adjacent to the receiver 5. It is clear that the same effect can be obtained if the operation margin indicator 8 is located at a position where the operation can be confirmed during installation or maintenance.

Further, although an optical signal was used as the remote control signal, it is clear that the same effect can be obtained not only with optical signals but also with ultrasonic signals and electromagnetic wave signals.

As explained above, the elevator remote control device according to the present invention is provided with an operating margin indicator that indicates that the remote control signal from the transmitter is being transmitted and received with a strength equal to or higher than a predetermined value. The adjustment operator can see the operating range even if temperature or voltage fluctuations occur, and if the adjustment is made so that this operating margin indicator is activated, the operating range will be greater than the predetermined magnitude even if temperature or voltage fluctuations occur. Since the distance does not become small, it is possible to prevent the phenomenon of inability to perform remote control, which has the extremely excellent effect of (b).

Claims (1)

[Claims] An elevator remote control device includes a transmitter that sends a remote control signal as a medium such as radio waves, ultrasonic waves, or light, and a signal processing circuit that receives the remote control signal from the transmitter and sends the control signal to the elevator control device. The remote control signal is operated at a value equal to or higher than the minimum value of the remote control signal plus the variation of the remote control signal so that the remote control signal from the transmitter is transmitted and received with a strength equal to or higher than a predetermined value. An elevator remote control device characterized by being equipped with an operation margin indicator.
