Description

The present invention relates to a vehicle traffic control device including an open / close bar for controlling permission or disapproval of traffic in an ETC (registered trademark) lane at the entrance or exit of a highway or a toll road.

In the conventional vehicle traffic control device of this type, the open / close bar provided in the control device is opened after the payment process of the fee is finally completed by the appropriate communication between the roadside wireless device and the vehicle-mounted device. The vehicle can pass through the pass gate.
The opening / closing bar rotates in a direction perpendicular to the road surface and perpendicular to the traveling direction of the vehicle so that the opening / closing state of the opening / closing bar can be satisfactorily visually recognized from the inside of the vehicle where the vehicle driver slowly travels. It is configured as follows.
That is, the open / close bar is formed to rotate in a vertical plane with respect to the road surface.

However, this conventional vehicle traffic control device has the following various problems.
If the vehicle cannot be stopped immediately before the opening / closing bar in order to prevent the vehicle from passing, the vehicle will collide with the opening / closing bar and the opening / closing bar will be damaged.
For this reason, the current device is provided with an impact avoidance mechanism that allows the opening / closing bar to rotate in the horizontal direction of the road surface at the part that drives the opening / closing bar. However, the breakage / damage of the opening / closing bar itself is unavoidable. It is.

Once the vehicle collides with the opening / closing bar, the opening / closing bar opens until it becomes parallel to the vehicle traveling direction, a lock mechanism for preventing rebounding acts, and the opening / closing bar is fixed. Therefore, in order to return the apparatus to a normal use state, an operator needs to go to the place where the apparatus is installed and reset the apparatus.
In a traffic gate provided with ETC (registered trademark), it is impossible to predict when a collision will occur. Therefore, an operator for resetting the opening / closing bar must always be arranged at a toll gate or the like.

The worker has to go to the vehicle traffic control device where the collision has occurred for resetting, but it is also necessary to cross the driving lane in the middle of the collision, and there is a possibility of encountering an accident with the traffic vehicle.
In the traffic control devices described in the following patent documents, all of the open / close gates rotate up and down perpendicular to the road surface.
Reference 1 aims at further downsizing the opening / closing bar drive device, and Reference 2 aims at preventing troubles at the time of power failure of the opening / closing bar.

JP 2008-127911 A JP-A-11-61752

Therefore, in the present invention, in order to solve the above-mentioned problems, the following matters are the subjects.
First of all, minimize the damage and breakage of the open / close bar of the vehicle traffic control device.
In other words, even if a passing vehicle collides with the open / close bar, damage and breakage can be minimized.
In addition, when the collision with the open / close bar cannot be avoided, the open / close bar should be able to be opened.
Furthermore, even if the vehicle collides with the opening / closing bar, there is no need for the operator to manually reset the opening / closing bar.
In addition, when a power failure occurs, when a pair of left and right open / close bars is used, if one of them breaks down, adopt a more efficient configuration for maintenance and maintenance of the device, and open / close bar visibility It is also an object of the present invention to prevent damage.

A first aspect of the present invention is a vehicle traffic control device that is installed at an entrance or exit of a toll road or the like and is provided with an open / close bar that regulates vehicle traffic. The vehicle traffic control device includes a drive unit therein. A main body having a rotating portion that is connected to the driving portion and protrudes from the upper portion of the main body to the outside, and an opening / closing bar having a root portion fixed to the rotating portion. axis is parallel to the traveling direction of the vehicle, and, the rotating shaft is disposed in a state inclined with respect to the road surface, thereby, the opening and closing bars is rotated forward and obliquely upward of the vehicle passing direction opening The vehicle traffic control device is characterized in that it operates and rotates in the opposite direction to perform a closing operation .
Here, because the front of the vehicle passing direction "obliquely upward" is meant to include both of the opening and closing operation of "linearly obliquely upward" or "curved manner obliquely upward" rotation.

According to a second aspect of the present invention, there is provided the vehicle traffic control device according to the first aspect, wherein an inclination angle that rotates obliquely upward is in a range of approximately 25 degrees to approximately 55 degrees with respect to the road surface. It is.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a vehicle detection sensor that detects a vehicle approaching in front of the opening / closing bar is provided, and when the vehicle is detected by the vehicle detection sensor, the opening / closing bar is A vehicle traffic control device that is opened.

  According to a fourth aspect of the present invention, there is provided the vehicle traffic control device according to any one of the first to third aspects, wherein the opening / closing bar is opened when a load more than a predetermined load is applied to the opening / closing bar.

According to a fifth aspect of the present invention, in any one of the above-described inventions, the main body of the device is provided at a symmetrical position on both sides of the road as a pair of right and left when viewed from the vehicle traveling direction. If one of the devices fails, the opening / closing bar of the one device opens to maintain the open state, and the vehicle traffic can be controlled by the operation of only the opening / closing bar of the other device. This is a vehicle traffic control device that is configured as described above.

  According to a sixth aspect of the present invention, in any one of the above inventions, the open / close bar has a substantially circular cross-sectional shape, and two different colors of paints are alternately applied to the surface in a spiral shape. The vehicle traffic control device.

In the first one of the present invention, since the opening / closing bar is turned upward and obliquely upward in the vehicle passing direction, even if the passing vehicle collides with the opening / closing bar, the direction of the impact is directed forward, There is no contradiction with the pivoting direction of the opening / closing bar, so that the opening / closing bar is pushed forward, and the opening / closing bar and the front part of the vehicle come into contact with each other, but the impact is reduced, and the opening / closing bar and the vehicle It becomes possible to minimize damage and breakage of the device.
In addition, the opening / closing bar does not rotate in the front horizontal direction, but rotates obliquely upward and retracts, so that the driver can visually recognize the state in which the opening / closing bar is opened (the state of jumping up). It is also possible.

  Further, the connecting portion between the opening / closing bar and the rotation shaft of the opening / closing bar is movable by a universal joint or the like, and the base of the opening / closing bar is guided by a guide rail or the like, so that the turning trajectory of the opening / closing bar is adjusted in a curve. It is also possible. And, by setting this turning track to the collision (substantially horizontal) direction on the closed state side and setting it to a curved track gradually guided to the upward track, the function of absorbing and mitigating the energy at the time of the collision can be exhibited. At the same time, since the initial speed of the opening operation appears to be slow when viewed from the driver (initially rotates in a substantially horizontal direction), it is possible to expect a speed suppressing effect of the passing vehicle. However, it is advantageous to simply rotate it linearly and obliquely upward from the relationship between the mechanical complexity and the opening speed.

  In the second aspect of the present invention, in the first aspect, the range of the angle that is rotated obliquely upward of the opening / closing bar is limited, and the visibility of the driver is best secured within this range. It will be possible.

In the third aspect of the present invention, in the first and second aspects of the present invention, the open / close bar does not perform any active retraction operation against the collision of the passing vehicle, but the vehicle detection sensor detects the collision of the passing vehicle. By detecting by this, the opening / closing bar is immediately opened.
This is intended to prevent contact between the open / close bar and the vehicle. Even if the vehicle and the opening / closing bar come into contact with each other, the opening / closing bar itself opens and closes, so that damage to the opening / closing bar and the vehicle can be minimized.

According to a fourth aspect of the present invention, the opening / closing bar performs an opening operation when a load more than a predetermined load is applied to the opening / closing bar.
As a result, when the vehicle collides with the open / close bar, the open / close bar can be opened. On the other hand, even if a heavy load such as a typhoon causes a load below a predetermined level, the open / close bar malfunctions and opens. It is possible to prevent this from happening.

  According to a fifth aspect of the present invention, in a vehicle traffic control device of the type provided with a pair of left and right open / close bars, when one of them fails, one of them automatically performs an opening operation to maintain the opened state. By setting, the vehicle traffic control can be performed only with the other opening / closing bar.

  In the sixth aspect of the present invention, in order to maintain the visibility of the open / close bar, paints of two different colors are alternately applied in a spiral shape, whereby the open / close bar rotates obliquely upward. In this case, the two-color zebra pattern can be visually recognized by the driver.

The embodiment which concerns on the vehicle traffic control apparatus of this invention is illustrated, The (A) is a top view, The (B) is a front view. The opening / closing bar which is the principal part of the said embodiment which concerns on this invention is illustrated, The (A) is a partially cutaway side view, The (B) is an enlarged view of the action | operation part of an opening / closing bar. The opening / closing bar which concerns on other embodiment of this invention is illustrated, The (A) is a see-through | perspective side view, The (B) is a see-through | perspective enlarged view of the action | operation part of an opening / closing bar. In the vehicle traffic control apparatus which concerns on embodiment of this invention, what provided the vehicle detection sensor which detects the position of an approach vehicle is illustrated, The (A) is a top view, The (B) is a front view is there. It is a top view of what provided the vehicle detection sensor from which the detection position of an approach vehicle differs in the vehicle traffic control apparatus which concerns on embodiment of this invention.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 illustrates an embodiment according to a vehicle traffic control device of the present invention, in which (A) is a plan view and (B) is a front view.
The vehicle traffic control device 10 according to this embodiment is composed of a pair of left and right bodies, and is formed of a main body portion 11 and an opening / closing bar 12 having a pivot shaft on the upper front side of the main body portion 11.

  The pair of vehicle traffic control devices 10 and 10 are installed on both sides of the road surface R passing through a traffic gate installed at an entrance or exit of an expressway or the like, and the opening / closing bar 12 is in the vehicle traveling direction with respect to the road surface R. It rotates in the inclined surface inclined forward, and is rotated 90 degrees upward and obliquely upward, and jumps up.

In other words, the rotation part 14 at the base of the opening / closing bar 12 is provided on the inclined surface 13 whose front side corner of the upper surface of the main body 11 is chamfered.
Therefore, the open / close bar 12 is different from the conventional one that jumps vertically upward, and turns up and jumps up in an obliquely inclined state in the traveling direction of the vehicle.

Spiral red paint 12r is applied to the open / close bar 12 on a white background, and even if the open / close bar 12 is rotated upward, the driver can follow the zebra pattern of two colors red and white at any rotation angle. It is comprised so that it can visually recognize favorably.
As a means for rotating the opening / closing bar 12, any means such as an electric motor or a hydraulic motor may be used.

As described above, the open / close bar can be rotated not only linearly but also in a curved manner in the inclined surface inclined forward in the vehicle traveling direction.
In other words, the connecting part between the pivot shaft for rotating the opening / closing bar and the opening / closing bar is made movable by a universal joint or the like, and the base of the opening / closing bar is guided by a guide rail or the like so that the opening / closing bar is curved (on the upper surface). It is also possible to rotate it to a convex or curved surface convex to the lower surface.
When the opening / closing bar is rotated in a convex curve on the lower surface, the initial movement of the opening / closing bar is almost horizontal, so the opening operation of the opening / closing bar is slow to be visually recognized by the driver, and the vehicle driving speed The effect is that it can be restricted when entering the passing gate.

FIG. 2 illustrates an opening / closing bar that is a main part of the embodiment according to the present invention, in which (A) is a partially cutaway side view, and (B) is an enlarged view of an operating part of the opening / closing bar. .
In this embodiment, an electric servo motor 20 is used as a driving means for the opening / closing bar 12.
In the ETC (registered trademark) lane, when the roadside wireless device and the vehicle-mounted device of the passing vehicle communicate appropriately and a passage permission command is issued, the servomotor 20 is energized and the servomotor 20 rotates. Accordingly, the opening / closing bar 12 is rotated obliquely upward, and the opening / closing bar 12 is opened.

When the vehicle passes through the vehicle traffic control device 10, this is detected by a vehicle passage detection sensor (not shown), and the servo motor 20 is reversely controlled.
If the vehicle collides with the open / close bar 12 at a high speed and cannot be handled by the servo motor 20, it is held by the return spring 21 wound around the outer periphery of the support shaft of the open / close bar 12 inside the rotating portion 14. The open / close bar 12 is released by removing the bearing and prevents the open / close bar 12 and the servo motor 20 from being damaged. The bearing portion is locked again in a state in which the opening / closing bar 12 is completely open, thereby preventing a return due to a collision.
In this embodiment, the rotation inclination angle θ with respect to the road surface of the open / close bar 12 is set to 40 degrees. Since ± 15 degrees of this angle is the angle at which the vehicle driver can best visually recognize the pivoting movement of the opening / closing bar, it is necessary to adjust the inclination and alignment of the entire road.

It should be noted that the rotational inclination angle θ is not a problem at all if it is between approximately 25 degrees and approximately 55 degrees, and is appropriate, but can be set as necessary.
When the angle of inclination is smaller than this angle range, visibility from the driver is deteriorated. When the angle of inclination is larger than this range, the opening / closing bar and the vehicle are damaged when the vehicle collides with the opening / closing bar. There is a risk that the above will increase.

Further, in this embodiment, although not shown, a torque sensor is provided on a support shaft that pivotally supports the opening / closing bar 12, and this torque sensor has a load higher than a load load of, for example, a wind speed of 40 m / s. The sensor is set to operate to open the opening / closing bar when loaded.
This prevents the open / close bar from being opened by wind up to a wind speed of 40 m / s, and when the passing vehicle collides with the open / close bar, the open / close bar is automatically opened by the collision load. The action can be performed. However, in the case of a violent collision, the opening / closing bar 12 is released by the action of the return spring 21 as described above.
Of course, a vehicle detection sensor is separately provided to deal with the problem of collision of a passing vehicle, as will be described later.

FIG. 3 shows an open / close bar according to another embodiment of the present invention, as in the previous figure, in which (A) is a transparent side view, and (B) is a transparent enlarged view of an operating portion of the open / close bar. It is.
In this embodiment, an electric cylinder 30 is used as an operating means for the opening / closing bar 12.
By the operation of the electric cylinder 30 installed in the upper part of the main body 11, the reciprocating motion of the cylinder rod 31 is converted into the rotational motion, and the support shaft of the open / close bar 12 is rotated to open the open / close bar. it can.

That is, in the ETC (registered trademark) lane, when the roadside radio device and the vehicle-mounted device of the passing vehicle communicate appropriately and a permission command is issued, the electric cylinder 30 is energized and the cylinder rod 31 is extended. Thus, the support shaft is rotated, and the opening / closing bar 12 is rotated obliquely upward, and the opening / closing bar 12 is opened.
When the vehicle passes through the vehicle traffic control device, this is detected by a vehicle passage detection sensor (not shown), and the electric cylinder 30 is reversely controlled.
If the vehicle collides with the open / close bar at high speed, the bearing held by the return spring 21 wound around the outer periphery of the support shaft of the open / close bar 12 is released and the open / close bar 12 is released. The electric cylinder 30 is prevented from being damaged. The bearing portion is locked again in a state in which the opening / closing bar 12 is completely open, thereby preventing a return due to a collision.

As described above, the present invention employs a configuration in which the opening / closing bar 12 is turned up and slanted forward and obliquely upward in the traveling direction of the passing vehicle.
For this reason, in an ETC (registered trademark) lane, etc., it is unpredictable that the roadside wireless device and the vehicle-mounted device are not properly communicated and the vehicle enters the traffic gate with the open / close bar closed. If this happens, the vehicle will collide with the open / close bar. At the time of the collision, the open / close bar itself is configured to move forward from the structure. The impact resistance in the event of a collision will be less.

FIG. 4 illustrates a vehicle detection sensor that detects the position of a vehicle entering the vehicle traffic control device according to the present invention, in which (A) is a plan view and (B) is a front view. FIG.
The vehicle detection sensor 18 is provided on the front side and the vehicle entry side of the main body 11 of the vehicle traffic control device 10, and the detection direction S is parallel to the state where the open / close bar 12 is closed.

That is, the vehicle detection sensor 18 is provided so as to detect a state immediately before the vehicle V collides with the opening / closing bar 12. An optical sensor is used as this sensor.
Therefore, when the vehicle detection sensor 18 detects the presence of the vehicle, the opening / closing bar 12 is instructed to open, the servo motor is energized, and the opening / closing bar 12 is immediately opened. Yes.

Thereby, the impact caused by the collision between the opening / closing bar 12 and the vehicle V is further reduced, and damage to the opening / closing bar 12 and the vehicle V can be minimized.
Of course, for vehicles that have passed in such a state, after passing through the vehicle traffic control device, display or notification of abnormal or illegal passing is displayed with a guide plate or warning sound, etc. Processing is performed.

FIG. 5 illustrates an embodiment in which a vehicle detection sensor is provided in the vehicle traffic control device according to the present invention as in FIG. 4, but the detection positions of the sensors are different.
That is, the vehicle detection sensor 18 is provided on the front side of the main body 11 of each vehicle traffic control device 10, that is, the vehicle entry side. The vehicle detection sensor 18 is different from the embodiment shown in FIG. It is installed so that it can be detected when the approaching vehicle is positioned not in front of the bar 12 but on the near side.

Specifically, it is necessary to change this detection position depending on the approach speed of the vehicle V, but in this drawing, assuming that the approach speed of the vehicle V is 60 km / h, the linear distance from the center line of the opening / closing bar 12 is It is set to 2145 mm.
Thus, the opening operation of the opening / closing bar 12 is immediately performed when the vehicle detection sensor 18 detects the vehicle V that has entered at a speed of 60 km / h without issuing an opening command to the opening / closing bar 12. It was configured as follows. Thereby, before the approaching vehicle V collides with the opening / closing bar 12, the opening / closing bar 12 performs an opening operation, and the collision between the opening / closing bar 12 and the front portion of the vehicle V can be avoided, thereby preventing damage to both. It can be done.

The optical sensor 18 is a columnar sensor and is set so that several optical sensors are installed at the height of the vehicle tip (between the ground height of 500 mm and 1000 mm), and the opening operation is started by detecting one or more of them.
As described above, the optical sensor is installed at a certain distance in front of the opening / closing bar in consideration of the speed of the approaching vehicle and is adjusted so as not to open too quickly. In addition, it is prevented from being accidentally opened due to fallen leaves or the like by being installed above the ground height of about 500 mm.
In addition to the optical sensor, there is a footboard type sensor, and ETC (registered trademark) uses a sensor that counts the number of axes. However, since the vehicle weight is applied, the life and maintenance are inferior, so the optical sensor is considered advantageous.

As mentioned above, although embodiment of this invention was described, it can change and implement various forms as follows.
First, in the above embodiment, a pair of left and right vehicle traffic control devices are used, but this is implemented by either the left or right vehicle traffic control device, that is, as a vehicle traffic control device with a single opening / closing bar. You can also

Actuating means and mechanisms for rotating the open / close bar can also be selected and used as appropriate.
It can also be carried out by covering the open / close bar with a cover for preventing damage.
As the vehicle detection sensor, an optical sensor is used in the above embodiment, but other detection means can be used.
Further, the position for detecting the vehicle can also be set as necessary.
When a pair of left and right vehicle traffic control devices are installed, the left and right control devices are configured to operate independently, and even if one of them fails, the other control device is configured to operate normally. You can also.

When the electric drive device is used as the opening / closing bar operating means, the battery can be used in the event of a power failure so that the opening / closing bar is automatically left open or closed.
Furthermore, when the power failure state is canceled, the vehicle traffic control device can be configured to be remotely controlled to return to the normal state. For example, it is possible to return to a normal state by performing an operation of interrupting the operation of the battery by wireless communication.
Similarly, if one of the pair of devices fails, the vehicle can be opened only by opening / closing the opening / closing bar of the other device by opening the opening / closing bar of the failed device and leaving it open. It is possible to perform traffic control. In this case, when one of the devices fails and the motor cannot be driven, the opening operation is performed by a spring or the like by electrically releasing the bearing of the opening / closing bar of the one failed device.

It is also possible to easily replace the opening / closing bar, actuator, and control panel of the vehicle traffic control device so that when these components fail, only those portions can be easily replaced.
As described above, the present invention has been able to provide a vehicle traffic control device that has a simple configuration and exhibits extremely remarkable effects.
