Description

Description: TECHNICAL FIELD The present invention monitors the rolling of a passenger car (hereinafter referred to as a gondola) on a ropeway installed in a ski resort or the like, and warns when the rolling exceeds a preset value. The present invention relates to a gondola roll monitoring device that generates a.

Conventional technology Ropeways installed at ski resorts, etc. may cause the gondolas to collide with the steel poles if the gondolas roll sideways due to strong winds, and the gondolas may become detached from the track ropes and become inoperable. . For this reason, conventionally, a TV camera is installed beside the steel pillar, and the station guards monitor the image of the gondola sent from this TV camera on the monitor TV, depending on the shaking state of the gondola at that time. It controls the transport speed of the gondola and decides to suspend operation.

Problems to be Solved by the Invention However, conventionally, since the gondola is photographed by the TV camera, it is difficult to photograph the gondola under bad weather such as sudden fog and snowstorm. There was a problem that I could not monitor the gondola. In addition, since the horizontal movement of the gondola is monitored on the monitor TV, the mental and physical fatigue of the observer becomes great, and the judgment of the shaking state of the gondola to control the transport speed of the gondola is monitored. There was a problem that it was different depending on the member, and thus it was not possible to operate safely.

The present invention has been made in view of the above problems, and can monitor a gondola even under sudden bad weather without any trouble, and it makes the amount of shaking accurate without mechanizing the judgment and individual difference. It is an object of the present invention to provide a ropeway gondola roll monitoring device that can detect and perform safer operation and at the same time reduce the burden on the observer. In addition, an alarm is issued when the deflection angle exceeds a dangerous deflection angle (safety limit deflection angle), and in particular, the safety limit deflection angle that differs depending on the position of the operating route is properly reflected. It also aims to enable detailed safety management. By the way, if the alarm is issued based on the same judgment criteria over the entire route, it is unavoidable to set the alarm with a small deflection angle according to the most dangerous place, and even with a larger deflection angle. Even if it is possible to secure sufficient safety in other places where there is no need, the alarm will be output sensibly, which is not suitable for reality.

Means for Solving the Problems According to the present invention, the above problems are solved by the gondola (G ₁ , G ₂ , ...,
G _n ), which is composed of a tilt sensor and a wireless device, wirelessly outputs the measured tilt angle of the gondola (G ₁ , G ₂ , ..., G _n ), which is a gondola terminal (7 ₁ , 7 ₂ , ..., 7 _n ), And an iron pillar that is placed along the operation route of each gondola and stretched with a track rope (R),
Satellite repeaters (S ₁ , S ₂ , ..., S _n ) that are located at (P ₁ , P ₂ , ..., P _n ) and consist of wireless devices and data transmission devices, and each gondola at a fixed position in the operation route. (G ₁ , G ₂ , ..., G _n ) can be individually identified to read the gondola monitoring number and output a monitoring number signal as an operation monitoring start signal, and a gondola number reading device (G) ₁ , G ₂ , ..., G _n ) outputs a moving distance step signal (2) each time it moves a fixed distance, and a side of the gondola (G ₁ , G ₂ ,, ..., G _n ). A storage unit (3) that stores a reference tilt angle that means a critical tilt angle limit value of the gondola (G ₁ , G ₂ , ..., G _n ) for each of the wobbling detection range data groups and each of the wobbling detection range data. , When the operation monitoring start signal output from the gondola number reading device (1) is input, the travel distance data held corresponding to the gondola _{L 1, L 2, ...,} L n) Initializes the gondola moving amount detector (2) moving distance increment signal when the inputted every travel distance data output from the (L _1, L _2, …, L
by adding a predetermined value to _n) to update the value, and all the moving distance data _{(L 1, L 2, ...} , the value of L _n) is a predetermined storage. If it is within the range in which lateral vibration should be detected, the gondola terminals (7 ₁ , 7 ₂ , ..., Of the gondola) are wirelessly transmitted through the satellite repeaters (S ₁ , S ₂ , ..., S _n ). 7 _n ), the measured tilt angle is obtained and the position signal of the gondola and the measured tilt angle signal are output, and the measured tilt angle value is individually obtained and stored in advance in association with the roll detection range. A central processing circuit (4) that outputs an alarm signal only when the value is larger than the reference tilt angle value, and an alarm is issued when the alarm signal is input, and the individual gondola (G ₁ , G ₂ , ..., G _n the moving distance data (L ₁ the operating position of the)
L _2, ..., to display the L _n), also constitutes a gondola roll monitoring device ropeway out with Release Monitoring so as to display the corresponding measured tilt angle value (5).

The tilt sensor of the working gondola is designed to wirelessly output the measured tilt angle in response to a signal from the satellite repeater that constantly detects the swing angle. The gondola movement amount detector installed in a station or the like outputs a movement distance step signal to the central processing circuit every time the gondola (track rope) moves a certain distance. When the gondola passes through the fixed position of the station, the gondola number reading device reads the gondola monitoring number of each gondola and outputs the monitoring number signal to the central processing circuit.The central processing circuit outputs the travel distance data for each gondola. initialize. The central processing circuit keeps track of the current position of each gondola by adding a constant value to each moving distance data each time the moving distance stepping signal is input. When the current position of the gondola matches any of the roll detection range data groups in the storage unit, the central processing circuit determines the individual reference tilt angle corresponding to the roll detection range data and the measured tilt angle via the satellite repeater. Then, the two are compared, and an alarm signal is output only when the actually measured inclination angle value is larger than the reference inclination angle value, and an alarm is issued by a buzzer sounding on the monitoring panel. It should be noted that the operating position of each gondola and its measured tilt angle value are visually displayed on the monitoring panel.

If it is larger than the data, an alarm signal is output to the monitoring panel (5) and the alarm buzzer sounds (step 8). Therefore, the guard at the station (Sa) may control the transport speed of the gondola only when the alarm buzzer is activated. If the measured inclination data is smaller than the reference inclination data as a result of the comparison, the gondola (G ₁ , G ₂ , ..., G _n ) will be operated as it is. In this way, each gondola is monitored to see if it does not exceed the dangerous angle determined for each location according to the operating position, and there is no individual difference and safe operation of the gondola is possible, and the burden on the observer is also light.

As described above, according to the present invention, based on the read gondola monitoring number, the moving distance of the gondola is detected and the position and tilt of the gondola in the roll detection range are displayed. It is possible to monitor the gondola even under adverse weather conditions. In addition, the appropriate safety limit deflection angle that differs for each position of the operating route is used as a reference, and when the deflection angle causes a danger of exceeding the safety limit deflection angle for each position, an alarm is issued to burden the observer.
