The departure permission lamp GL is not lit.
[0021]
FIG. 8 shows the start of operation of the two transporters 10 and 10 (No. 1 machine 10a and No. 2 machine 10b) and the progress of data transmission of line connection during operation. Since the progress of communication between the two transporters 10 and 10 (No. 1 machine 10a and No. 2 machine 10b) is the same, a description will be given of one of the transporters 10 (No. 1 machine 10a). The driver who has boarded the transporter 10 presses the driving push button PB3. The photocoupler PC6 reads this operation, converts it into digital data, transmits it with the wireless device 14, and in response to receiving the digital data at the Yamagata stop 2 side, the control panel 22 relays the wireless control unit 21. When R3 is turned on, the operation magnet CX1 is turned on, and the operation condition is established by the control panel 22, the two carriers 10, 10 start operation, and the operation relay CR is turned on. The photocoupler PC3 of the wireless control unit 21 reads the ON operation, converts it into digital data, and transmits it with the wireless device 20. When the portable device 10 receives such digital data, the operation relay RR in the wireless control unit 14 is turned on, and the operation lamp RL of the operation operation unit 16 is turned on. Data transmission proceeds in the same manner for the other carrier 10 (No. 2 machine 10b).
[0022]
When the operation of the transporters 10 and 10 starts, a line connection confirmation signal is sent every 10 seconds from the Yamagata stop 2 and when an answer back signal is received from the transporter 10 side, the relay R7 of the radio control unit 21 is turned on. Turn on the device normal magnet GX1. For the transporter 10, when the line confirmation data sent from the Yamagata stop 2 can be received, the device normal relay YR of the radio control unit 16 is turned on, and the device normal lamp YL of the operation unit 16 is lit.
[0023]
On the other hand, if the answerback signal cannot be received twice continuously from the carrier 10 in response to the line connection signal transmitted every 10 seconds from the Yamagata stop 2, the relay 7 of the radio control unit 21 Is turned off, and the device normal magnet GX1 is also turned off. Similarly, when the line confirmation signal transmitted every 10 seconds from the Yamagata stop 2 cannot be received on the carrier 10 side, the device normal relay RY of the wireless control unit 14 is turned OFF, and the operation control unit Sixteen device normal lamps YL are turned off. In this way, the operating personnel of both the Yamagata stop 2 and the transporter 10 can confirm the state of wireless communication while the transporter 10 is operating the cableway 4. The communication state of the other transporter 10 (No. 2 machine 10b) is similarly confirmed.
[0024]
FIG. 9 shows the progress of data transmission when the decelerating operation is performed with the transporter 10. When a driver who gets on the transporter 10 switches the high-speed / low-speed selector switch SS of the driving operation unit 16 to the deceleration side, the photocoupler PC8 of the wireless control unit 15 reads the switching operation and converts it into digital data. send. When such a digital data is received by the radio device 20 at the foothill stop 2 and the relay R6 in the radio control unit 21 is turned on, the contact B is turned off and the high-speed / low-speed switching magnet FX1 is turned off and is self-held to be carried by the carrier 10. , 10 are decelerated from the normal (high speed) operation speed to the low speed. Further, when the answerback signal is transmitted from the radio device 20 at the foot of the Yamagata stop, and the answerback signal is received by the radio device 14 of the carrier 10 in response, the driving operation unit 16 has been lit since the start of operation. The lamp RL and the device normal lamp YL continue to be lit as they are.
[0025]
Subsequently, when an operator of the transporter 10 returns the high-speed / low-speed selector switch SS of the operation unit 16 to the original high-speed side, the photocoupler PC9 of the radio control unit 16 converts the digital data to the switching operation, and then the radio unit 14 send. When such digital data is received by the radio 20 at the Yamagata stop 2, the A contact of the relay R6 is turned off, so that the B contact is turned on, the high speed / low speed switching magnet FX1 is turned on again, and it operates at a low speed via the control panel 22. The transporters 10 and 10 inside are accelerated and return to the normal (high speed) operation speed again.
[0026]
Similarly to the case of the deceleration operation described above, when the answerback signal is transmitted from the Yamagata stop 2 by the wireless device 20 and the answerback signal is received by the wireless device 14 on the carrier 10 side in response, The operation lamp RL and the apparatus normal lamp YL are continuously lit from the start of operation. However, even if the digital data is retransmitted five times by the wireless device 14 in response to the high-speed / low-speed switching operation of the driver from the above-described transporter 10, such digital data cannot be received at the Yamagata stop 2, or the transporter 10 decelerates, or If it is not possible to return to the normal operation speed, the transporter 10 cannot receive the answer back signal from the Yamagata stop 2, and in this case, the device normal lamp YL of the operation unit 16 of the transporter 10 blinks for 10 seconds. Inform the operator of the situation where data could not be transmitted.
[0027]
FIG. 10 shows the progress of data transmission when an emergency stop operation is performed on the transporter 10. When the driver in the transporter 10 presses the emergency stop push button PB4 of the driving operation unit 15, the operation is read by the photocoupler PC7 of the wireless control unit 15, converted into digital data, and transmitted by the wireless device 14. When the radio device 20 at the Yamagata stop 2 receives the digital data and sends it to the radio control unit 20, the relay R4 is turned on, and the emergency stop magnet DX1 of the control panel 22 is turned on to satisfy the emergency stop condition. The transporters 10 and 10 that are in operation are emergency stopped. At the same time, when the answerback signal is transmitted from the radio device 20 from the foothill stop 2 and the answerer signal is received by the radio device 14 of the carrier 10, the device normal lamp YL and the operation lamp RL of the operation control unit 16 start operation. The lighting state from is continued. However, even if the digital data is retransmitted five times by the wireless device 14 in response to the emergency stop operation of the driver from the above-described transporter 10, the digital data cannot be received at the Yamagata stop 2, and the emergency of the transporters 10, 10 If the vehicle cannot be stopped, the answer back signal cannot be received from the foothill stop 2, and in this case, the device normal lamp YL of the operation unit 16 of the transporter 10 blinks for 10 seconds from the lighting and is operated by the driver. Inform the user that the data could not be transmitted.
[0028]
The above has described the details of the wireless operation system in which the operation personnel of the carriers 10 and 10 wirelessly control the operation of the own vehicles 10 and 10 in the crossing ropeway 1, but the operation personnel other than the crossing ropeway Of course, it is possible to apply the present invention to a cableway of a type operated by a transporter on which the vehicle rides.
