Abstract

PURPOSE:To attain data transmission, speaking, etc., for operation control without laying a dedicated communication line by forming a closed loop by a pair of supporting cables and the ground and transmitting data, calling, etc., by way of the closed loop. CONSTITUTION:The equipment has a induction line loop L being the closed loop obtained by making each of both ends of a pair of supporting cables 1a and 1b of a cableway, etc., to be grounded. The data transmission of operation control between the top and the foot of a mountain is sent from a transmitter 4 at the foot to a receiver 8 on the top by way of an antenna, the loop L and the antenna of the receiver 8. On the other hand, data is sent from a transmitter 7 on the top to a receiver 5 by way of the same route. Furthermore, data can be transmitted also from the transmitter 11 and the receiver 12 of a carrier 10 to a towline 2 being the induction line loop L for operation control. Besides, speaking is executed between the transmitter 7 and the receiver 8 on the top, the transmitter 4 and the receiver 5 at the foot and the transmitter 11 and the receiver 12 of the carrier 10 one another by way of the towline 2 being the loop L. Consequently, the towline is used as it is so as to unnecessitate the dedicated communication line.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guideway radio apparatus used for data transmission for controlling operation of a cableway such as a ropeway and for telephone calls.

[0002]

2. Description of the Related Art Conventionally, there has been used a method of laying a dedicated communication line between the foot of a mountain and the top of a mountain for data transmission for communication control of a cableway such as a ropeway and communication. However, with this method, construction of aerial or underground burial of communication lines is not easy depending on the site conditions, and wind,
It was accompanied by problems such as difficulty in maintenance due to damage from snow and lightning.

DISCLOSURE OF THE INVENTION The present invention solves the above conventional problems and provides a guideway wireless device for a cableway, which can perform data transmission for operation control, telephone communication, etc. without laying a dedicated communication line. For the purpose of provision.

[0004]

In order to achieve the above-mentioned object, the present invention is: 1. A guide wire loop closed by a pair of stanchions and ground, a transmitter at a stop connected to the guide wire loop, and 1. A cable-guided wireless device including a receiver. It is an object of the present invention to propose the cable-guided radio apparatus according to claim 1, wherein a transmitter and a receiver of the carrier are also connected to the guide wire loop.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The cable-guided radio apparatus of the present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows a cable-guided radio apparatus according to the present invention. The cable-guided radio apparatus grounds each of both ends of a pair of ropes (1a) and (1b) of a cableway such as a ropeway to a closed loop via the ground. It has a guide wire lube L.

A transmitter (4) and a receiver (5) are connected to the guide wire loop L at the foot of the mountain. As a method of connecting the transmitter (4) and the receiver (5), a direct connection method,
There are a method of magnetically connecting via a matching transformer (3), a method of electromagnetically connecting via an adjacent antenna (a method shown in the figure), and the like.

On the other hand, the guide line loop L is connected to the transmitter (7) and the receiver (8) at the summit in the same manner as at the foot of the mountain. In the illustrated embodiment, the foot of the mountain and the summit of the mountain are shown as the stops, but the transmitter and the receiver can be connected to other stops such as an intermediate station.

Next, a carrier (10) (one, two or more) suspended from and supported by the stanchions (1a), (1b) is also equipped with a transmitter (11) and a receiver (12). As shown in FIG. 2, the transmitter (11) and the receiver (12) are attached to the support cord (1).
a) An antenna (1 that is close to the rope (1b) as well)
4) Electromagnetically connected via (15).

That is, the carrier (10) cannot be directly connected to the guide wire loop L for moving or by a matching transformer, and therefore the carrier (10) is connected through the antennas (14) and (15). Here, the reason why the transmitting antenna (14) and the receiving antenna (15) are separated and a predetermined distance is provided is to prevent mutual interference.

The function of the cableway guiding wireless device of the present invention shown in the above embodiment is as follows. That is, data transmission for operation control between the foot of the mountain and the summit is sent from the transmitter of the foot of the mountain (4) to the receiver of the summit (8) via the antenna, the guide line loop L and the antenna of the receiver of the summit (8). On the other hand, it is sent from the transmitter (7) at the summit to the receiver (5) at the foot of the mountain via the same route.

Further, data may be transmitted from the transmitter (11) and the receiver (12) of the carrier (10) to the guide wire loop L for controlling operation. On the other hand, for communication, the transmitter (7) and receiver (8) at the summit, the transmitter (4) and receiver (5) at the foot of the mountain, and the transmitter (11) and receiver (12) of the carrier (10) are mutually exchanged. Through a guide wire loop L between.

Next, FIG. 3 shows an embodiment in which a matching transformer (3) is used in the transmitter (4) at the foot of the mountain. Further, FIG. 4 shows a case in which one support line (1a) (the same applies to the support line (1b)) is composed of two support lines. That is, in this case, by short-circuiting the two support lines and sending a signal to each support line, it is possible to prevent the signal from being cut off due to the short-circuiting of the two support lines at the portion of the carrier (10). .

[0013]

The embodiments of the cable-guided radio apparatus of the present invention are as described above, and the effects thereof are listed below. (1) The inductive wireless device of the present invention does not need to lay a dedicated communication line because the inductive line loop is formed by the pair of stanchions and the ground. (2) The inductive wireless device of the present invention is a device to which electromagnetic induction is applied in particular and is not caused by spatial radio waves, so there is little risk of interference.
