Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a safe operation management system for a cableway carrier, particularly a ropeway, and more specifically, a method for detecting the position and swing state of a carrier on a cableway, and the detection results thereof. Concerning safe operation management systems, including information transmission methods, etc.

(Prior Art) Cableway @ Device 1 For example, a ropeway is smaller than a large transport vehicle for railways, etc., but it is generally an advantageous vehicle from the viewpoint of construction costs as a transport vehicle in rugged mountains.

However, in general, the natural environment of mountains is harsher than that of flatlands, and various measures to ensure safety in such a natural environment are extremely necessary.

Especially for ropeway facilities, strong winds cause the gondola to sway horizontally and vertically, and when constant swaying occurs, the gondola comes into contact with or collides with the rope support tower, which is extremely dangerous.

In addition, when the tension of the rope decreases, not only the horizontal sway but also the vertical sway, that is, the M sway, increases, and there is a risk that the rope will come off the support tower or the gondola itself will fall off the rope.

For this reason, conventionally, wind speed indicators (llll
We will install I meters and monitor them at all times, and we will suspend operation in steady-state strong winds and temporarily stop operation if the wind speed decreases. The government was in charge.

As for the slack in the sagging rope, I compared it with the experience of the vertical sway from a test ride in a gondola, and in the evening (feel the constant swaying) and correct the tension of the rope. I was doing the sakujo.

However, all of the conventional safety management systems, such as a series of series, lack accuracy and speed, and it is difficult to say that they are sufficient1. With the method of pushing the tremors of
Regular UI? It is not effective as an effective way to prevent danger.

Conventional empirical methods for measuring the slack of 1M suspension ropes were not accurate and were extremely vague methods.

(Objective of the Invention) The present invention was developed in view of the above-mentioned circumstances, and an object of the present invention is to provide a more accurate safe operation management system for cableways [particularly ropeways].

(Summary of the Invention) In order to achieve this object, the present invention includes a rolling or pitching detecting means 4, for example, an acceleration sensor for measuring acceleration in each direction, and a swing width is calculated from the acceleration. By providing a means for transmitting this detected information to the operation manager, a means for detecting the position of each of the nine III vehicles on the cableway, etc., the shaking of the carrier itself can be corrected in real time.

Furthermore, based on this observation result, measures such as stopping the movement of the carrier or reducing its speed are taken to prevent accidents.

(Example) The present invention will be described in detail below based on an example shown in one figure.

Furthermore, this central monitoring device 1 is equipped with base radio station equipment 7 as an attachment E-1, and at stations and rope-suspended steel towers along the cableway route, there are signboard devices 8- for providing position information, etc. to passing gondola-mounted equipment. 1) Place s-, +...

Moreover, the carriers 9, . 9. -2°K is the carrier's own device 10. ．． ．． , 1.10-2. The carrier itself is equipped with a radio transmitter/receiver 1), an endogenous control device 12 for the carrier 2, an infrared transmitter/receiver 13, and a transponder 14 for decoding the signal from the infrared transmitter/receiver 13. And, based on the acceleration sensor 15 that detects at least the lateral acceleration IL fe and the output of the sensor, the lateral force sway width? :The main blocks include a displacement transducer 16 for detection and a power supply device 17 including a storage battery.

Further, the sign post device 8-1 * 8-2 +...
. . . includes an infrared transmitter/receiver 18 and the central monitoring device 1.
includes a remote controller 3, an interrogator 19 and an uninterruptible power supply 20 connected by wire.

First, a case will be described in which the apparatus W1 configured as described above is used to accurately detect rolling motion and its position during transport of a carrier.

FIG. 2 is a schematic diagram of a low sea urchin system in which the above-mentioned devices are installed at predetermined parts.

That is, in the figure, 1 and 7 are the central monitoring device installed in the control room of Building 7 and the base station wireless equipment attached to it, and the sign post device 8-1 connected to this device by wire is the first steel tower 21. Place it in the required part.

Also, although not shown, similar sign posts 8-2.8-, 8-2.

Furthermore, in the same figure, '1', 12 are gondolas which move while being suspended from ropes, and the above-mentioned intra-carrier devices &Th1(1), 10- are mounted inside the gondolas.

In this state, each gondola! ,,J2 moves along the rope, but when passing through the steel tower 21 or the station on the way, there is a sign post 8. ．． 8-,,...
It receives position information superimposed on infrared rays and sent out from ..., and calculates the position of the carrier on the rope from this information and the moving speed of the carrier.

The information indicating this position may be, for example, the sign post i and the elapsed time after passing this sign post, or the distance from the actual reference position on the jJ-p may be calculated from the three pieces of information. .

Furthermore, in the 9 internal devices 10-1, 10-2+, etc., the acceleration sensor detects the swing width of each carrier, and when it exceeds a predetermined constant value.

A message to that effect or the measurement result is transmitted together with the position information of the mobile device via the wireless transceiver.

The information thus transmitted is transmitted to the main controller 2 via the base station radio 7 and the remote controller 3, and the information is compared with the information stored in the database memory 4. For example, if the database is the relationship between the position of the carrier and the maximum allowable swing width at that location, this data is compared with the information sent from the carrier every moment, and this is the maximum allowable swing width at that location. When the swing range is exceeded or approaches the value, a message to that effect is displayed, and control is performed such as stopping the movement of the @ device or slowing down the movement speed.

According to this method, information on the shaking of the carrier itself can be collected continuously and in real time while it is moving, so it is much more accurate than the conventional method using an anemometer.

Note that when there are a large number of carriers, it is not necessary to install these devices on all the carriers, and it may be sufficient to keep a few on hand, and the information to be collected is not limited to the rolling of the carrier. It is also possible to add the amount of pitching.

The method for measuring vertical vibration of a carrier includes an acceleration sensor that detects vertical acceleration as well as horizontal vibration.

The swing width can be measured by differentiating the output twice.

When measuring the sway of a transport vehicle, care must be taken to take measures to exclude data from areas where the transport vehicle is subject to significant sway, such as platforms at intermediate stations.

In other words, the two departure stations and intermediate stations are equipped with platforms for passengers to board and alight.

When a carrier enters the core area or departs again, the carrier and the platform may come into contact and cause abnormal shaking, but it is unlikely that this shaking will cause an i-signal to be issued or the movement of the carrier to be controlled. It's bad.

Therefore, as shown in Fig. 3, the station building signal and its release signal 0 are transmitted to the equipment in the carrier via infrared or ultrasonic transmitting and receiving equipment provided at the entrance and exit of the station building, and the shaking information is transmitted from the carrier by the station building signal. The transmitting function is temporarily stopped, and the stopped function is activated again by a release signal when leaving the station building. This means allows smooth operation.

According to the present invention, in addition to the above-mentioned shaking of the carrier due to the wind, it is also possible to measure the looseness of the lobes.

In general, it is mandatory for ropeway equipment to measure the tension of the robe on a regular basis, but until now, clear measuring methods and equipment have not been established, and only empirical measurements have been taken. As mentioned above.

According to various experiments, it has been found that the nine-system carrier described in Figures 1 and 2 above with a pitch measuring device added can collect data that can be used to estimate the tension of the lobe. did.

In other words, if the robe is too loose, it will shake as the carrier moves! The vertical sway soon became larger.

This shaking was noticeable near the steel towers that support the robes.

Furthermore, since the lobe position of the support tower and the lowest position of the lobe can be determined from the amount of displacement in the vertical direction of the vessel, the actual tension of the lobe becomes clear.

What causes the change in the tension of the robe?

Temperature changes, changes over time, or changes in the ground on which the steel tower was built may be considered, but with the above method, it is possible to quickly detect the loosening of the lobes caused by these changes.

Same 1 Implementation of the present invention - CI-1: Above implementation 14.
For example, instead of using a wireless transmitter/receiver as a means of transmitting information between the carrier and the main controller, infrared rays or
) -C may be used depending on the ultrasonic transmitter/receiver.

Furthermore, it is obvious that the means for detecting the vibration of the carrier may be replaced with a means having a similar function other than the acceleration sensor.

(Effects of the Invention) Since the present invention is configured and functions as explained above, it is possible to detect the shaking of a cableway carrier such as a ropeway in real time and accurately, and to detect the movement of a cableway vehicle such as a ropeway. It has a great effect.
