Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cableway network system applied to a ropeway, a gondola, etc., and particularly to a LAN (Local Area Net) for wirelessly or wired information about driving and other various information.
comprehensively using the work), high speed operation,
The present invention relates to a cableway network system with improved safety and convenience.

[0002]

2. Description of the Related Art Cableways such as ropeways and gondolas installed on sloping areas such as mountains, for example, are located at the foot of the foothill station, which is the driving section equipped with a driving device, and at the top of the mountain, which is a predetermined stop section. Between the mountaintop station and the mountaintop station, the carrier is moved using ropes and other ropes (fixed ropes) and load-supporting fixed ropes (supporting ropes) to carry people and loads. .

Usually, driving operations such as traveling and stopping of the carrier are
It is performed by the operator at the driver's cab at the foot of the station,
There are types such as automatic operation, semi-automatic operation, and manual operation. In addition, when an assistant etc. is on board the carrier and it is necessary to adjust the speed to switch to low speed operation due to weather conditions such as wind speed, the assistant in the carrier will give a wireless telephone call to the operator in the cab. Will be contacted and the speed will be adjusted by the operation of the operator. In some cases, the operation device is provided in the carrier to enable the speed adjustment operation inside the carrier, but in that case the operation is limited to speed reduction, stop, etc. from the viewpoint of safety, and for speed increase operation It is generally performed by a room operator.

[0004] Specifically, for example, when a cross wind is strong, the swing width of the carrier is enlarged, and an assistant can wirelessly communicate with a push button operation so that an operator can pass through while reliably preventing contact with a steel tower on the way. Will be contacted. It should be noted that contact is also made by wireless telephone (for example, Japanese Patent Laid-Open No. 2001-104
No. 86, Japanese Patent No. 30295753, etc.).

[0005]

By the way, in the conventional contact system by wireless communication, an indirect system is employed in which a signal from a push button is converted into data by a converter and indirect wireless transmission / reception is performed. Therefore, 1 for contact
It takes about a second to send and receive, and the response is not always agile. Further, the number of push buttons is set to, for example, only about ten, and the number of types of operations that can be selected is small.

As described above, the conventional cableway communication system lacks high speed due to radio communication, and there is still room for improvement in order to further improve safety and avoid danger.

For this reason, the equipment is complicated and the cost is increased.

Further, the use of communication is limited for each device, and the amount of information handled is generally small. For this reason,
There is also a lack of convenience in responding to various situations, and there is also a lack of convenience. Since the dedicated wireless equipment used for each purpose lacks versatility and cannot be easily applied to different cableways, the equipment cost is also increased from this point.

The present invention has been made in view of the above circumstances, and enables high-speed communication that is much faster than the conventional wireless communication speed, and enables mass transmission of various kinds of data. , The safety and convenience of the cableway can be further enhanced, and necessary information can be easily and quickly provided from any position of the cableway to a necessary place.

Therefore,
Not only can driving safety be enhanced, but emergency measures can be taken immediately.

Further, as a merit of unifying the LAN, safe and high-speed communication can be obtained. Further, since the LAN type network is used, data can be guaranteed and loss can be compensated. That is, there is no loss of data, and even if it is lost, it can be retransmitted, so that the characteristics of the LAN can be obtained. Further, since data, video, voice and the like can coexist, the safety confirmation by the video and the like can be promptly and surely performed by contacting the driver and the moving person.

Further, since the data can be sent on the screen, the control information can be seen even in the carrier 5, which is extremely large in the case of the present embodiment as compared with the data communication which has a limited capacity in the past. Can send the data of.
In addition, it is possible to easily know the number of people by waiting at the station. Therefore, according to the present embodiment, in the past, such as high-speed driving, convenience, safety, handling when a danger occurs, etc., what only a driver mainly can do in the past can be swiftly and surely performed by anyone anywhere. Will be able to.

In the case of a ropeway that crosses the summit, radio waves by SS radio may not reach the opposite side of the mountain. In such a case, a relay LAN, which is connected by wire or wirelessly, is arranged in the middle of the cableway, and roaming is performed between the relay LAN and the carrier to thereby perform communication between terminal devices belonging to each individual LAN. Can be possible. For example, FIG. 3 shows a cableway network system provided with such a relay LAN. As shown in FIG. 3, a relay antenna 3 for roaming is provided on the summit.
6 is installed so that the SS radio can be transmitted and received between the station building at the foot of the station 1, the station building at the station 2a on the opposite side of the mountain, and the respective carriers 5 via the relay antenna 36. As a result, the foothill station 1 and the station 2a on the opposite side of the mountaintop
, The foothill station 1 and the carrying device 5, and the carrying device 5 and the station 2a on the opposite side of the summit, or between the carrying devices 5 can communicate with each other by SS radio.

The above-mentioned SS wireless LAN and relay L
A LAN using a wireless network for satellite communication can be applied instead of the AN or the like. In some cases, a wired L
It is also possible to apply a data link of an AN, for example a computer network such as Ethernet.

In this embodiment, the crossover type ropeway has been described, but the present invention is not limited to such a type, and can be similarly applied to other various cableways such as a gondola. Moreover, since the range in which SS wireless communication is possible is, for example, a range of 1 to 10 km, these can cover the entire wide area,
Moreover, high speed communication becomes possible by sharing with the PHS radio network. Within the scope of these PHS radio networks, voice calls between terminal devices such as mobile phones and various mobiles,
High-speed communication such as data communication can also be used. That is, even in a mountainous region where there is no PHS line network as a public line network, there is an advantage that each unique communication network can be formed.

[0039]

As described above, according to the present invention, safety and convenience can be further improved by high-speed communication and use of a large amount of various data, and necessary information is required from all positions of the cableway. It is an object of the present invention to provide a cableway network system that can be provided at a specific location and that can be easily obtained as a general-purpose base material and can be implemented as low-cost equipment. For example, even when an abnormality occurs in the monitoring target, the abnormality information can be promptly and surely transmitted to the administrator or the like, and a quicker response can be taken.
