The radio signals w1 and w2 of 0 are constantly received, and the signals are output to the logic circuit 24. The output unit 25 has a relay 26 and this contact 28, and a relay 27 and this contact 29. Thus, by receiving the radio wave signal w1, the relay 26 is in the excited state by the command of the logic circuit 24, and therefore the contact 28 is closed as shown in FIG. Electricity is maintained. Similarly, since the radio signal w2 is received, the relay 27 is in an excited state by a command from the logic circuit 24, the contact 29 is also kept closed, and the emergency stop circuit 32
Has been maintained.

The security circuit 30, that is, the deceleration circuit 31 and the emergency stop circuit 32 are connected to the central control unit 33 for cableway operation. Thus, the deceleration circuit 31 and the emergency stop circuit 32 are energized. As far as is possible, the operation of the cableway is constantly maintained.

The above is a description of the steady state. Next, a description will be given of a case where the apparatus is not in a steady state and an operation thereof.

If the attendant 64 carrying the transmitter 10 on the mission recognizes the need to decelerate the cableway operation, for example, when a child or a person unfamiliar with getting on and off gets on and off, the deceleration shown in FIG. The push button 14 is operated. That is, in FIG. 3, when the deceleration push button 14 is operated, the normally closed contact is opened, and the transmission of the radio wave signal w1 transmitted from the transmission unit 18 via the transmission antenna 19 is stopped by a command of the logic circuit 17.

Immediately operates the emergency stop push button 15 shown in FIG. 4 in the case of an emergency that discovers or predicts some danger. That is, in FIG. 3, when the emergency stop push button 15 is operated, the normally closed contact is opened, and the transmission of the radio signal w <b> 2 being transmitted from the transmission unit 18 via the transmission antenna 19 by the command of the logic circuit 17 is stopped. You.

On the other hand, in the receiver 20, the receiving section 22
Has stopped receiving the radio wave signal w2, the relay 27 of the output unit 25, which has been kept closed as shown in FIG. 3, is de-energized by the command of the logic circuit 24, and the emergency stop circuit 32 Is turned off. Therefore, the emergency stop of the cableway operation is performed by the central controller 33 for the cableway operation, and thus the safety of the operation is ensured.

[0031]

It is needless to say that if a danger or danger is expected as a matter common to traffic transportation equipment, measures such as a stop should be taken immediately to ensure safety. For the treatment in such a case, a fixed operation stand has conventionally been provided near a boarding / alighting platform in a cableway stop, and when a staff member such as a passenger staff or a monitoring staff discovers an abnormality, the push button is operated. And then take deceleration or safety measures.
However, in this case, the clerk must rush to the position of the operation stand, and when the clerk is away from the position of the operation stand, there is a problem that measures are delayed.

As a response to this, a device proposed by "wireless driving device for cableway" or the like has already been known, but this device is supposed to transmit a signal only in an emergency, Radio signals are not transmitted, so there is a risk of malfunctions such as unnecessary operation stop, for example, when external disturbance such as noise radio waves is intercepted by the receiving side. be pointed out. On the other hand, the present invention has been made in order to eliminate such adverse effects and to provide a highly reliable wireless control device that operates reliably.

That is, in the configuration of the present invention, the transmitter,
The contacts used for both receivers always maintain the closed state, and the radio signals are always transmitted and received, so they have a fail-safe configuration and a highly secure configuration. I have. Also, there is little possibility of malfunction due to accidental reception of noise radio waves from the outside. Further, in the configuration of the present invention, the radio signals w1 and w2 have a characteristic configuration in which deceleration, stop, and the like can be distinguished by using a plurality of waves that can be identified by, for example, frequency modulation.

Therefore, the present invention has an effect that it can be used effectively for ensuring the safety of cableway driving.
