JPH0939793A - Opening direction detector of turnout - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent such accidents as derailment of maintenance vehicle at a turnout or damage on the turnout by making a vehicle to decelerate on this side of the turnout to run slowly, forcing it to make emergency stop by detecting the opening direction of the turnout at a specified position approaching to the turnout or allowing it to pass the turnout as in its slow running. SOLUTION: When a maintenance vehicle (called 'vehicle' hereafter) advances to a turnout P1 from a side line C, at first, a signal of a vehicle slow running indicator 2C composed of a permanent magnet placed on pillars is detected by 4 magnetic sensors installed on the lower part of the body of vehicle so as to make slow running owing to brake pressure. The vehicle advances by a distance L1 as in its slow running and when it reaches the position of an opening direction indicator 3C, if turnout P1 is switched to the main line side, as no electromagnetic wave is oscillated from the indicator 3C, it is decided that the turnout P1 is switched to the main line side (side line is closed) from the output of the electromagnetic sensor on the vehicle so that an emergency stop may be carried out.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in order to prevent a derailment accident or the like at a track branch point of a maintenance vehicle on a railway, slows down the vehicle at a predetermined distance before the branch switch and opens the branch switch. The present invention relates to a device which detects a direction and allows a vehicle to pass slowly while the branch switch is switched to the opening direction and automatically stops before the branch switch when the branch block is blocked.

2. Description of the Related Art A maintenance vehicle such as a motor car is indispensable in order to maintain and manage the condition of a track in good condition, and has been widely used permanently. However, this maintenance vehicle normally waits on a side line in the station yard, and if necessary, embarks on the main line to perform track maintenance work. Then, when the maintenance vehicle goes out of the side line to the main line, or when it finishes the work and returns from the main line to the side line, it must pass through a switching point point (hereinafter simply referred to as a branch point).

At the branch point, normally, the main line is in a completely open state, and when a maintenance vehicle moves out of the side line to the main line, the branch point is switched to open the side line.
The main line needs to be closed.

Further, the main line is cross-connected to a large number of branch points, and the number is large especially in the station yard. When the maintenance vehicle approaches a branch point while passing through such a main line, the vehicle runs while checking the opening direction of the branch point each time, and the maintenance vehicle derails or the branch point is damaged. It was necessary to prevent accidents.

[0005]

However, under the present circumstances, when the maintenance vehicle approaches the vicinity of the branch point, the driver visually confirms the opening direction of the branch point. The driver only controls the maintenance vehicle accordingly.

Such visual confirmation by the driver may be neglected especially in an emergency dispatch, which may lead to a derailment accident of a maintenance vehicle or a breakage accident of a branch point. Even when I was dispatched, I rarely forgot to check visually because of the driver's carelessness, and several derailment accidents or branch point damage accidents occurred throughout the year. In addition, if the driver is obliged to visually check the opening direction of the branch point, it may cause mental and physical fatigue of the driver, and it may not be possible to completely check the opening direction due to weather conditions. Yes, it was extremely difficult.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the embodiments of the invention shown in the drawings. 1 to 4 show an embodiment of the present invention. FIG. 1 is a plan view showing a ground arrangement of the entire apparatus, and FIG.
Is a schematic block diagram of the determination device that detects the opening direction of the branching device and outputs a signal to the opening direction command device, FIG. 3A is a side view of the maintenance vehicle, and FIG. 4 is a block diagram of the vehicle control device.

As shown in FIG. 1, the ground equipment of this opening direction detecting device includes a vehicle slow-moving indicator 2A to a vehicle slow-moving indicator 2A consisting of permanent magnets facing both sides of the sleepers located on the front side L ₂ of the turnout 1. 2D is installed. Permanent magnet is 15 cm
It is a ferrite magnet having a size of × 10 cm × 5 cm.
Further, at a position approaching the branching device 1 side by a distance L ₁ from the vehicle creeping indicators 2A to 2D, opening direction commanders 3A to 3D including electromagnetic wave transmitters that emit electromagnetic waves of 100 KHz are tilted at 45 degrees. It is installed upward.

On the other hand, the branching switch 1 is provided with a changeover detection switch 4 for detecting the opening direction of the branching switch 1.
The change detection switch 4 is a proximity switch that detects the movement of the arm 1a of the branch 1. These ground facilities are installed on both the main and side lines. Thus,
The signal from the changeover detection switch 4 is output to the judging device 5, which judges whether the branching device 1 is switched to the main line or the side line, and either the main line or the side line opening direction commander 3A or 3C is selected. One or 3B or 3D
The command is issued to either one of the above. As shown in FIG. 2, the determination device 5 uses a battery 6 and a solar cell 7 as power sources. This power is also supplied to the changeover detection switch 4 and the opening direction command devices 3A to 3D.

Normally, the solar cell 7 supplies power to each device during the day, and the surplus power is stored in the battery 6, and the power is supplied from the battery 6 at night or when it is cloudy. The battery 6 is set to have a capacity that allows each device to operate for 30 days even if the solar cell does not generate power.

FIG. 3A and FIG. 3B show the maintenance vehicle 8. On the underside of the vehicle body on both sides of the front part of the maintenance vehicle 8, there are provided a total of four magnetic sensors 9 for receiving signals from the vehicle creeping indicators 2A to 2D, two magnetic sensors 9 on each of the left and right sides. On the lower surface of the vehicle body on both sides of the center portion of the maintenance vehicle 8, the opening direction commands 3A to 3D are provided.
Corresponding to the above, two electromagnetic wave sensors 10 are installed, one on each of the left and right sides, which is installed by inclining downward at 45 degrees.

FIG. 4 shows a vehicle control device 11 of the maintenance vehicle 8. The control device 11 controls the voltage-air converter 12 based on a program of a microcomputer determined in advance according to the signals from the four magnetic sensors 9 and the two electromagnetic wave sensors 10, and the brake cylinder 13 Decelerate by changing the brake pressure that acts on
Vehicle control such as slowing down, emergency stop and cancellation is performed.

The vehicle control device 11 is also adapted to attach a pulse oscillator to a meter cable of a vehicle speedometer and calculate the traveling distance and speed of the vehicle by means of the pulses, and output a braking signal and a release signal. I am taking it out. Further, the vehicle control device 11 has an abnormality detection sensor for the magnetic sensor 9 and the electromagnetic wave sensor 10. Abnormality detection is that a current of several mA always flows when power is supplied to each of the sensors 9 and 10. However, when the current stops flowing, an alarm is output and an alarm is issued to the driver. To inform you.

Next, the operation mode of the opening direction detecting device for the branching device constructed as described above will be described with reference to the ground facility layout diagram of FIG. 1 and the flowchart of FIG. Incidentally, FIG.
In the above, “when facing backward” means a case of traveling from a forked line side to one line side. In the state shown in FIG. 1, the branching device P1 is switched to the main line side, and the proximity switch 4 detects this and outputs it to the determination device 5. The determination device 5 outputs to the opening direction commander 3A on the main line side so as to oscillate an electromagnetic wave of 100 KHz according to the signal from the switch 4, and the opening direction commander 3 on the side line C is output.
C does not oscillate electromagnetic waves.

In such a state, it is assumed that the maintenance vehicle 8 starts traveling from the point A side of the main line toward the branch switch P1. When maintenance vehicle 8 reaches a distance in front L ₂ from splitter P1, line both sides of consisting installed a permanent magnet on the sleepers vehicle creep indicator 2A, the magnetic field lines of the 2A, underbody maintenance vehicle 8 The four magnetic sensors 9 provided in the sensor detect. That is, the "slow command" is detected.

As a result, the vehicle control device 11 shown in FIG.
Indicates that the brake pressure of the brake cylinder 13 is 0.4 Kg / cm ^{2 to} 3 depending on the approach speed of the maintenance vehicle 8 at that time.
Control is performed in the range of Kg / cm ² , and the maintenance vehicle 8 is gradually decelerated until the speed becomes 5 Km / h or less per hour. The reason for gradually decelerating is that the maintenance vehicle 8 is often loaded with ballast, sleepers, and other loads, and when sudden braking is applied, these loads collapse and scatter on the track, causing a secondary disaster. This is because there is a risk of causing After the stepwise deceleration, the cruising operation is performed while the brake pressure is maintained at 0.4 Kg / cm ² .

The maintenance vehicle 8 reaches the position of the opening direction command device 3A after a while in the "slow running mode". This command device 3A
Generates electromagnetic waves because the branching device P1 is switched to the main line side, and the electromagnetic wave sensor 10 of the maintenance vehicle 8
Detects this. Thereby, the vehicle control device 11
It is possible to detect that the diverter P1 has been switched to the main line side, and instruct the maintenance vehicle 8 to continue the "slow operation".

Then, the vehicle control device 11 measures the pulse signal from the pulse oscillator attached to the meter cable of the speedometer of the vehicle, and the maintenance vehicle 8 advances the distance L ₂ from the detection of the slow drive command and moves to the branch device P1. When passing, there is no risk of derailment accidents or damage to the turnout, so "deceleration cancellation" is instructed and the brake pressure of the brake cylinder 13 is released. That is, normal maintenance is performed and predetermined maintenance work is performed.

On the other hand, in the state shown in FIGS. 1 and 5,
When the maintenance vehicle 8 travels from the side line C toward the diverter P1, first, the magnetic sensor 9 detects a signal from the vehicle creeping indicator 2C, and 0.4 Kg / cm ^{2 to 3} Kg / cm.
^The slow running by the brake pressure of ² is started. And
When the distance L _{1 is} advanced while driving slowly, the opening direction command device 3
Although the position of C is reached, the command device 3C does not oscillate an electromagnetic wave because the branching device P1 is switched to the main line side,
The electromagnetic wave sensor 10 does not detect electromagnetic waves.

Therefore, the vehicle control device 11 is provided with the branch device P.
It can be seen that 1 is switched to the main line side, and the side line is closed, so the brake pressure is 4
Perform "emergency stop" at Kg / cm ² . In other words, if the branching device P1 enters from the side track while being switched to the main line side, it may cause a derailment accident or a damage to the branching device. The vehicle 8 is automatically stopped in an emergency.

Next, referring to FIGS. 1 and 6, the main line A
The maintenance vehicle 8 that has passed the turnout P1 from the side
The state of "at the time of facing" progressing toward the side line D through 2 will be described. This "when facing each other" is when traveling from one track to a forked track. In this case, since the branching device P2 is switched to either one, the maintenance vehicle 8 does not cause a derailment accident or an accident such as damaging the branching device P2. Maintenance vehicle 8
Is either a normal track or a different track.

Thus, in the state shown in FIG. 1, the branch device P2
Is switched to the side line D side, and the maintenance vehicle 8 that has passed through the branching device P1 passes through this branching device P2 and reaches the position of the opening direction command device 3D. The command device 3D is
Since the branching device P2 is switched to the side line D side, it oscillates an electromagnetic wave. Therefore, the vehicle control device 11 receives the electromagnetic wave of the command device 3D by the electromagnetic wave sensor 10. When the vehicle 8 further advances, it will reach the positions of the slow speed indicators 2D and 2D this time, and the vehicle control device 11 will receive the slow command signal by the magnetic sensor 9.

In this way, when going from the point A side of the main line to the side line D through the branching device P2, there is no risk of derailment accidents or branching device damage accidents at the branching device P2. In addition, the opening direction command signal from the command device 3D and the slow drive command signal from the slow drive indicator 2D are received in the reverse order of the case of going to the branching device, but in this case, the above-mentioned derailment accident or the like occurs. Because I do not get it, without slowing down or making an emergency stop,
Proceed on lane D by performing "ignore drive".

By the way, when the electromagnetic wave of the opening direction command signal is received after passing through the branching device P2 and entering the side line D, the installation distance L of the opening direction detecting device is set.
_When a slow-moving detection signal is output by the magnetic sensor 9 after passing through ₂ , it means that a branching device other than these is installed at a certain position along the side line D, and the vicinity thereof was approached. In that case, the normal "slow" command is issued. And after that, A of the main line mentioned above
The control is performed in the same manner as when passing the branching device P1 from the side.

The present invention is not limited to the above-mentioned embodiments, but can be modified appropriately. For example, the installation status of the branch switch and the installation positions of the opening direction commander, the vehicle deceleration indicator, and the like for the brancher can be appropriately set according to the line configuration. When the maintenance vehicle 8 is stopped at the position of the opening direction command device as a closed circuit,
The program of the vehicle control device 11 may be configured to automatically restore after instructing the station staff or the like to switch the diverter 1 and confirming that the switch has been switched to the opening direction. It is also possible to configure the program so that the release pin is pulled out from the vehicle control device 11 and switched to the manual operation.

[0030]

As described above, in the present invention,
Decelerate before the turnout to drive slowly, and then automatically detect the opening direction of the turnout at a predetermined position closer to the turnout to make an emergency stop or pass the turnout in slow drive mode. Therefore, there is no accident that the maintenance vehicle causes a derailment accident at the turnout or damages the turnout. Further, it is possible to automatically confirm the opening direction of the branch switch and automatically operate the maintenance vehicle according to the confirmation, and it is possible to significantly reduce the burden on the worker.
