Abstract

PURPOSE:To automatically and surely carry out the changeover of transmission frequency by enabling one frequency generator to be switched over to the other frequency generator by means of the opening/closing operation of the door of a car gondola. CONSTITUTION:As a car gondola arrives at a station and a door is opened, the power source feed line contact of a door opening/closing switch 5 is turned off stopping the feed of a current from a storage battery 6 to CPU 4. Then, as the door is closed after completing the change of passengers, the power source feed line contact of the switch 5 is turned on feeding a current to the CPU 4. Thereby, the CPU 4 reads the contents of a direction specified route data from a first memory 7 to judge whether the advancing direction of the car gondola is an up route or a down route. At the time of the down route, an operation signal is outputted to a first frequency generator 8 and, after that, a direction specified route data with contents indicating the up route is written in the memory 7. On the other hand, in the case of the up route, an operation signal is outputted to a second frequency generator 9 and, after that, a direction specified route data with contents indicating the down route is written in the memory 7.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ropeway gondola roll monitoring device that is mounted on a gondola and automatically switches the transmission frequency between the up and down directions when the gondola departs. This invention relates to an automatic departure detection device.

2. Description of the Related Art Conventionally, when monitoring the rolling motion of a gondola based on the transmission frequency transmitted from the gondola, it was necessary to switch the transmission frequency between upstream and downstream directions when the gondola departs from a station. For this reason, a changeover switch is provided inside the gondola, and when the gondola departs, an attendant switches the changeover switch to change the multiplication frequency between the up and down directions.

In addition, since a rechargeable battery is used as a power source, when the gondola is stored in a garage, the staff in charge turns off the power switch to prevent power consumption during inspection work.

Problems to be Solved by the Invention However, since the operation of this changeover switch is done manually, it is often forgotten to change the switch, and therefore it is not possible to reliably change the transmission frequency between the upstream and downstream directions. There was a problem.

Furthermore, when the gondola is stored in a garage, the staff turns off the power switch during inspection work, so there is a problem in that the power supply cannot be shut off reliably.

The present invention has been made in view of the above-mentioned problems, and it is possible to reliably switch the transmission frequency between the upstream and downstream directions when the gondola departs, and to reduce the power consumption while the gondola is stopped. To provide an automatic departure detection device in a gondola sway monitoring device for a ropeway that can save money and eliminate the need for power cutoff work during inspection work when storing a gondola.

Means for Solving the Problems According to the present invention, the above-mentioned problems are solved by using a first frequency generator and a first frequency generator to detect the roll angles of the gondola in the up direction and down direction, which are detected by the inclination angle sensor. In a ropeway gondola rolling monitoring device that uses a second frequency generator with a different transmission frequency to transmit data via a transmitting antenna, it is connected to a power source and turns on and off by opening and closing the gondola door. a detection means, a storage means for storing the traveling direction of the gondola, and a storage means that operates when the door is closed and the door opening/closing detection means is turned on, and determines the traveling direction of the gondola based on the data content of the storage means. ,
A ropeway comprising: control means for outputting an operating signal to a frequency generator in the opposite direction to the data content of the storage means, and writing data content in the same direction as the frequency generator that outputs the operating signal into the storage means; This problem can be solved by using an automatic departure detection device in the gondola rolling monitoring device.

When the door of the operating gondola opens, the door opening/closing detection means is turned off and the current supply from the power source to the control means is stopped.

When the gondola door closes, the door opening/closing detection means is turned on, and the control means determines the traveling direction of the gondola based on the data content from the storage means, and operates the frequency generator in the opposite direction to this determined direction. By outputting a signal and writing data contents in the same direction as the frequency generator that outputs the operating signal into the storage means, one frequency generator is switched to the other frequency generator.

Example The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 shows a block diagram of an automatic departure detection device in a gondola rolling monitoring device for a ropeway, and this automatic departure detection device is mounted inside the gondola.

In FIG. 1, (1) is an inclination angle sensor that detects the rolling angle of the gondola, and this inclination angle sensor (1)
) is transmitted through an amplifier circuit (2) and an A/D converter (3) to an arithmetic processing unit (4) (hereinafter referred to as CPU).
) is output.

(5) is a door opening/closing detection switch connected to the battery (6) and turned ON/OFF by opening/closing the gondola door. This door opening/closing detection switch (5) turns OFF the power supply line contact from the battery (6) when the door opens, and turns ON when the door closes, causing the power supply line from the battery (6) to the CPU (4). Supply current.

When the CPU (4) is powered on by the current supplied from the battery (8), it reads the contents of the direction designation route data in the first memory (A). If this direction designation route data indicates that the gondola is going down, an activation signal is output to the first frequency generator (8) for the up route (upward direction), and this first frequency generator ( 8) is activated, that is, the direction designation route data indicating that the gondola is going up is written into the first memory (7). Also, if this direction specified route data means the gondola goes up, the down route (down direction)
At the same time, it outputs an activation signal to the second frequency generator (9) for the gondola, and also outputs the data content indicating that the second frequency generator (9) has been activated, that is, the direction designation route data with the content meaning the gondola's descent. Write to the first memory (7). Then, the tilt angle signal input from the tilt angle sensor (1) from time to time is compared with the individual set values of the tilt angle data read from the second memory (10), and the set value that matches the tilt angle signal is determined. It is constantly output to the signal conversion circuit (11) as swing angle data.

The first memory (7) is stored when the CPU (4) is powered off.
It stores the contents of direction designation route data from the CPU (4).

The second memory (lO) is stored when the power of the CPU (4) is OFF.
It is composed of elements whose data contents are not erased even if the gondola reaches F, and stores individual setting values set according to the rolling angle of the gondola as inclination angle data.

Then, each set value is sequentially output to the CPU (4) in response to an output command signal from the CPU (4).

The signal conversion circuit (11) converts the C as a parallel signal.
The swing angle data output from the PU (4) is converted into a signal format that can be transmitted electronically, that is, a serial signal, and the converted swing angle signal is sent to the first frequency generator (8) and the second frequency generator (9). Output.

The first frequency generator (8) is operated by an operating signal from the CPU (4) and transmits the swing angle signal input from the signal conversion circuit (11) to a transmitting antenna (12) at a predetermined frequency.
The swing angle from the tilt angle sensor (1) is transmitted by the transmitting antenna (12).

The second frequency generator (9) operates based on the operating signal from the CPU (4) and converts the swing angle signal input from the signal conversion circuit (11) into a predetermined frequency generator different from that of the first frequency generator (8). The frequency is output to the transmitting antenna (12), and the swing angle from the tilt angle sensor (1) is output to the transmitting antenna (12).
) is sent by.

Next, the operation of the automatic departure detection device will be explained with reference to the flowchart shown in Figure *2.

First, when the gondola arrives at the station and the door opens (
Step 1), the power supply line contact of the door opening/closing detection switch (5) is turned OFF (step 2). This stops the current supply from the battery (6) to the CPU (4).

Next, when the change of passengers is completed and the door is closed (step 3), the power supply line contact of the door opening/closing detection switch (5) is turned on (step 4), and the CPU (4)
A current is supplied to the CPU (4) and the power is turned on (step 5). This causes the CPU (4) to access the first memory (7).
) to read the contents of the direction specified route data (Step 6
), it is determined whether the direction of travel of the gondola is an up route or a down route (step 7). If the content of the direction designated route data means a down route, the first frequency generator (8)
The controller outputs an activation signal (step 8), and then writes direction designation route data indicating uphill in the first memory (7) (step 9). In addition, if the content of the direction designated route data means an up route, the second frequency generator (
9) to output the actuation signal to step 10), and then the first
Direction designation route data with content meaning downhill is written into the memory (A) (step 11).

When such a series of operations is completed, the process returns to the stage before step 1 and repeats the above series of operations.

Therefore, the first frequency generator (8) transmits the swing angle from the inclination angle sensor (1) as the transmission frequency for the up route while the gondola is in operation, and the second frequency generator (9) , While the gondola is in operation, the swing angle from the inclination angle sensor (1) is transmitted as a transmission frequency for the down route. In addition, when the door opens, the current supply to the CPU (4) stops, so you can save power while the gondola arrives at the station, that is, from when the door opens until it closes. If the gondola is stored in the garage in an open state, the power from the battery (6) will not be consumed.

Effects of the Invention As described above, according to the present invention, one frequency generator is switched to the other frequency generator by opening/closing the gondola door. Switching can be done automatically and reliably.

Furthermore, since the current supply to the control means is stopped when the gondola door is opened, power can be saved while the gondola is arriving at the station, that is, from when the door is opened until it is closed.

Furthermore, since the current supply to the control means is stopped when the door is open, opening the door ensures that the power is cut off during inspection work, and therefore the staff There is no need to turn off the power switch.

Furthermore, since the gondola can be stored with the door open, it can be used immediately at the start of work.
