Abstract

PROBLEM TO BE SOLVED: To allow vehicles to smoothly travel, and to smoothly attain traffic control by detecting the passage of a vehicle or the like in the neighborhood of a signal part, and switching the start or stop display of the signal part based on the passage information, and moving a preventing bar to an open or close position according to this switching. SOLUTION: Passage information detected by a detecting part 5 is transmitted from a crossing gate 1 through a radio communication part 35 to a control part 6. The control part 6 switches to the start or stop display of a signal part 4 of the crossing gate 1 based on the passage information. At the same time, a driving part 3 is driven so that the opening and closing of a preventing bar 2 can be operated by an arm 16, and the passage of the vehicle or the like can be controlled. Then, when the passage of the vehicle is heavy, the start display time of the signal part 4 or the opening time of the preventing bar 2 can be set long so that the passing time of the vehicles in a traveling direction with the heavy passage of vehicles, and otherwise, that can be set short. Thus, efficient traffic control can be selectively attained by setting various kinds of ways of control of the control part 6.

There is a problem that drivers with low morals, etc. tend to ignore this and pass through. In addition, since the switching of the start or stop display of the two traffic lights is performed at a predetermined time interval by the timer, no consideration is given to a large traffic volume of a vehicle or the like at all, and as a result, a traffic stagnation is caused. There is a problem that traffic control cannot be performed smoothly, for example, the waiting time increases.

Further, since the power source of the traffic signal is drawn out from the power transmission line with a cord, it cannot be used at a construction site in a remote mountainous area or the like. There is a problem that. Further, there is a problem that an electric wire for connecting the two traffic lights is required and the electric wire must be connected by an electric wire crossing the road, so that the installation work and its management become more complicated.

Further, even if a failure of a traffic light or an abnormality occurs in a wiring, a power supply, or the like, it cannot be found until an administrator goes around to a signal installation site, which hinders traffic control until that time. There is a problem.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
This will be described below with reference to the drawings. As shown in FIG. 1, the circuit breaker 1 has a long bar-shaped blocking bar 2, and a closed position for blocking the blocking bar 2 in a direction substantially perpendicular to a traffic direction of a vehicle or the like and a direction substantially perpendicular to the closed position. A driving unit 3 for driving the vehicle to open and close to an open position for releasing traffic, a signal unit 4 provided at a position visible from the traffic direction side of the vehicle and the like, and a detection unit for detecting traffic of the vehicle and the like near the signal unit 4 5, based on the traffic information from the detection unit 5, controls the switching of the start or stop display of the signal unit 4, and moves the blocking bar 2 to the open or closed position in conjunction with the switching. A control unit 6 for controlling the driving of the driving unit 3, the driving unit 3, the signal unit 4, and the detection unit 5
And a power supply section 7 for supplying power consumed by the control section 6 as main components. Among these, the drive unit 3, the signal unit 4, and the power supply unit 7 are fixed on a pedestal 10 with a rotating roller 8 and a support screw 9 below, and simultaneously move and fix at an installation place. It is free. Also,
The detection unit 5 is attached to the signal unit 4, the blocking bar 2 is attached to the drive unit 3, and the control unit 6 is installed at a separate place or attached to the circuit breaker 1.

The blocking bar 2 is formed by covering the outside of a core made of a long metal or synthetic resin molded product with a urethane foam resin, and further covering the outside with a shrink film. With such a configuration, the vehicle or the like is
Even if a collision or contact occurs, the shock is buffered, so that the vehicle or the like is not damaged, and the blocking bar 2 itself is not easily broken.
However, it is possible to use a long rod-shaped material without adopting such a configuration. The length of the blocking bar 2 is not particularly limited, but is preferably about 1 to 3 m. One end of the blocking bar 2 is detachably connected to the driving unit 3. It is even more effective to apply a luminous paint on the surface or to provide a luminous body at the tip so that the driver of the vehicle or the like can recognize the image even at night.

As shown in FIGS. 2 and 3, the drive unit 3 includes a motor 11 that rotates by supplying electricity from a power supply unit 7, an expansion rod 12 that expands and contracts by the rotational force of the motor 11, A connecting plate 14 having one end rotatably supported at the tip of the telescopic rod 12 and the other end fixed to the main shaft 13;
An arm 16 having one end fixed to the main shaft 13 and an attachment portion 15 for attaching the blocking bar 2 to the other end;
A control plate 17 fixed to the main shaft 13 has a main configuration. Since the connecting plate 14 rotates forward and backward as the telescopic rod 12 moves up and down in the outer cylinder 18 by the forward and reverse rotation of the motor 11, the main shaft 13 also rotates in the forward and reverse directions. Thereby, as shown in FIG. 4, the blocking bar 2 attached to the attachment portion 15 of the arm 16 also rotates to the closed position in a direction substantially perpendicular to the traveling direction of the vehicle or the like, and conversely,
It rotates and moves in the vertical opening direction that allows the passage of vehicles and the like. The driving unit 3 is housed in the cover because of the above configuration, and only the rotating arm is located on the outer side surface of the cover.

The control plate 17 detects the rotation angle of the main shaft 13 which is also the rotation angle of the arm 16 as shown in FIG. And the turning off or connection of the power supply. Thus, for example, when the main shaft 13 is rotated by a predetermined angle after a forward rotation command is issued to the motor 11 in order to rotate the blocking rod 2 to the open position, the power can be cut off and the rotation can be stopped. ing.

The arm 16 is provided in the power supply unit 7 when the power of the power supply unit 7 is almost exhausted, or when the power supply unit 7 is about to be in a state where the motor 11 cannot be driven, such as at the time of a power failure. The battery is provided with a return mechanism that switches to a spare battery, drives the motor 11, drives the motor 11, and returns to the vertical opening position where the blocking bar 2 releases the passage and stops.

Furthermore, the mounting portion 1 at the other end of the arm 16
5 is a receiving portion 19 fixed to the arm 16 as shown in FIGS. 4 to 7, and is fixed to the receiving portion 19 via a hinge 20 so as to be rotatable in the traveling direction of the vehicle or the like, and
It comprises a rotating block 21 to which the blocking bar 2 can be detachably attached. The tension spring 22 and one end of the gas cylinder 23 are fixed in the receiving portion 19, and the other end is fixed to the rotating block 21, so that when the blocking bar 2 is pushed in the traveling direction by a vehicle or the like, the hinge 20 is moved. It rotates around the center to prevent the blocking bar 2 and the drive unit 3 from being broken.
When the pushing by the vehicle or the like is released, the tension spring 2
2. It can return to the original position by the action of the gas cylinder 23 and the like.

As shown in FIGS. 4 to 7, the rotation block 21 has a rod insertion hole 2 into which the base end of the blocking rod 2 is inserted.
The cushioning rubber body 25 having the pressure member 4 is sandwiched between a pair of upper and lower pressing bodies 26. Also, this rotating block 2
A lever 30 is fixed to the upper end of a screw rod 29 screwed into a screw hole 28 formed in the top plate 27, while the lower end can press the upper pressing body 26 downward through an adjuster 31. It has become. Therefore, by rotating the lever 30 in the forward direction and pressing the upper pressing body 26 downward, the cushion rubber body 25 is compressed between the lower pressing body 26 and the lower pressing body 26 supported by the rotating block 21. Then, the blocking rod 2 whose base end is inserted into the rod insertion hole 24 is firmly fixed. Conversely, the upper pressing body 26 is raised by the restoring force of the cushion rubber body 25 due to the reverse rotation of the lever 30, so that the blocking bar 2 can be pulled out from the rod insertion hole 24. As described above, the cushioning rubber body 25 has a function of fixing the blocking bar 2 and also has a buffering function when a vehicle or the like collides with the blocking bar 2.

The signal section 4 is provided with a circular LED (light emitting diode) 32 for displaying start (blue) or stop (red) on the front side thereof, and the LE 32 above the LED.
A sun shade 33 for protecting D32 is attached. In a normal use state, the front side is arranged so as to face a direction in which a vehicle or the like passes. When the LED 32 is used, there is an advantage that the power consumption is small and the failure is small. However, as in the related art, it is possible to switch the display between red and blue.
Individual lights may be used. The signal section 4 is fixed above the support 34 fixed to the pedestal 10 and is provided at a position that is easy to see from the traffic direction side of the vehicle or the like.
By providing a structure in which the direction and height of the support 34 can be freely changed, it is possible to cope with a change in the installation location of the circuit breaker 1.

The detection unit 5 detects the traffic of a vehicle or the like, and detects a vehicle or the like stopped before a stop line marked on a road in front of the circuit breaker 1. It may detect a vehicle or the like passing in front of the circuit breaker 1. Further, the number of stopped vehicles or the like or the number of vehicles or the like passing per unit time may be detected. Since vehicles and the like pass through day and night, it is desirable that a sensor that can detect in any case be incorporated. Further, in the example shown in the figure, the detection unit 5 is mounted at a position facing the same direction as the LED 32 of the signal unit 4, but is not limited to this position, and can be a direction in which the traffic state of a vehicle or the like can be grasped. It should just be facing.

The control unit 6 is locked and built in the circuit breaker 1 such as the signal unit 4, or is installed in a place where it can be separately stored separately, and the control unit 6 itself is carried. It is free. Then, the control unit 6 stores the detection unit 5 in a program stored in the computer in advance.
When the traffic information is input, the driving unit 3 is driven to switch the start or stop display of the LED 32 of the signal unit 4 and to move the blocking bar 2 to the open or closed position in conjunction with the switching. Control to control the traffic of vehicles and the like.

As shown in FIG. 8, when two circuit breakers 1 are installed one by one near the starting point and the end point of the road construction section, the traffic information of both detectors 5 is used. Is transmitted to the control unit 6 located inside the other circuit breaker 1 or separately provided as shown in the drawing via the respective wireless communication units 35, and the control unit 6 The start or stop display of both signal units 4 is switched. In this case, when the signal unit 4 of one of the circuit breakers 1 switches from the start display to the stop display, the signal unit 4 of the other circuit breaker 1 switches from the stop display to the start display. The stop indications are overlapped by the passing time of the vehicle passing between the barriers 1,
Vehicles are prevented from entering the one-sided traffic area from both sides. The opening and closing of the blocking bar 2 by the driving unit 3 is controlled so as to open or close, respectively, in synchronization with the switching of the start or stop display of the signal unit 4.

Further, as another control method, while the traffic information from the detection unit 5 of one of the circuit breakers 1 and the traffic information from the detection unit 5 of the other circuit breaker 1 are constantly detected, both of the circuit breakers 1 are blocked. The display of the signal section 4 of the machine 1 is alternately switched while partially overlapping, and the switching timing is performed as follows, for example. When the detection unit 5 of the one of the circuit breakers 1 that is currently displaying the stoppage detects the vehicle ahead of the stop line, the display is switched to the transmission display after a lapse of a predetermined time (for example, 40 seconds). On the other hand, the other circuit breaker 1 displaying the start is switched to the stop display after a lapse of a predetermined time (for example, 30 seconds). The overlap of the stop display for 10 seconds here is because the time required for the vehicle to pass through the construction section is considered.

The display switching method of both circuit breakers 1 is as follows.
Various other methods are also incorporated. For example, as in the case where no traffic information is input to the control unit 6 for a certain period of time (for example, 60 seconds) from the detection units 5 of both of the barriers 1,
When there is no traffic of the vehicle or the like, the stop display is made to blink on both of the circuit breakers 1 and the vehicle is in a cautionary driving state, and when the detection unit 5 of either one of the circuit breakers 1 detects the traffic of the vehicle, immediately At the same time, the signal section 4 of the other circuit breaker 1 is changed to the stop display, and the signal section 4 of the other circuit breaker 1 is changed to the start display. Alternatively, when the traffic information is not detected by the detection unit 5 of the one circuit breaker 1 but the traffic information is detected by the detection unit 5 of the other circuit breaker 1, the signal unit of the one circuit breaker 1 is immediately transmitted. 4 is switched to the stop display, and the display of the LED 32 of the signal unit 4 of the other circuit breaker 1 is switched to the start display, thereby eliminating unnecessary waiting time of the vehicle, preventing driver irritation and smooth vehicle flow. It is controlled to be as follows.

When both the detectors 5 of the circuit breakers 1 continue to detect the traffic of the vehicle, the start display and the stop display are switched alternately at predetermined intervals by a timer while partially overlapping. There are various control methods other than those exemplified above, but the circuit breaker 1 of the present invention is applicable to any control method, and is not limited to any control method. Furthermore, by operating the operation panel provided in the control unit 6, the two circuit breakers 1 can be operated manually or semi-manually. The manual operation controls all the operations of the circuit breaker 1 by a manual remote control operation based on visual judgment by a staff member, and is used in an emergency. The semi-automatic operation is such that one of the two circuit breakers 1 is used as a master unit and a clerk operates a manual remote controller by visual judgment, and the other is linked with the operation of the master unit. Used when there are many construction vehicles.

The power supply unit 7 includes a battery for supplying power to the drive unit 3, the signal unit 4, the detection unit 5, the control unit 6, and the wireless communication unit 35. When there is a terminal of a power transmission line nearby, the power supply unit 7 may supply power by a cord from the terminal, charge the battery at all times, and switch to the battery only when a power failure occurs.

As shown in FIG. 10, the control unit 6 switches the display of the signal unit 4 of the circuit breaker 1 based on the traffic information from the detection unit 5 and drives the blocking bar 2 to be opened and closed by the driving unit 3. In addition to the control, when an abnormality occurs in the drive unit 3, the signal unit 4, the detection unit 5, the power supply unit 7, and the like, a function of immediately informing the abnormality manager of the construction site of the abnormality information is provided.
One of the means for informing is to use a wired or wireless telephone line. When the control unit 6 is independently installed in a construction management office or the like in which a telephone line is drawn in, the control unit 6 connects to a normal telephone line through a modem to notify the manager. Upon receiving such a report, the manager can dispatch a worker to the relevant construction site immediately for recovery. Further, if such a report is processed by the centralized management system, it is possible to efficiently manage the circuit breakers 1 at many construction sites. When a telephone line is not pulled in near the control unit 6, a report of occurrence of abnormality can be transmitted by connecting a wireless telephone, that is, a mobile phone, to the control unit 6.
Further, if the notification can be made directly to the worker's mobile phone, it is possible to go to the recovery immediately after the occurrence of the abnormality, so that inconvenience such as traffic stagnation can be minimized. When the manager is near the construction site, wireless communication may be used instead of using a telephone line.

The above-described abnormality information of the drive unit 3 includes a case where the drive unit 3 does not operate even though the power supply unit 7 is sufficiently charged and sufficient power is transmitted. Signal part 4
The abnormal information includes a time when the power less than necessary is supplied to the LED 32 and the start or stop display becomes impossible. As the abnormality information of the detection unit 5, the traffic information of the vehicle or the like for a predetermined time, for example, one hour, is not included in the control unit 6.
May not be entered. The abnormality information of the power supply unit 7 includes a case where the voltage of the battery drops below the voltage required for the signal unit 4 or the like. Examples of the abnormality information of the control unit 6 include communication control inability information such as information about passage of the detection unit 5 through the wireless communication unit 35 of the circuit breaker 1 being not obtained. Further, when the circuit breaker 1 is removed, or the signal unit 4, the cover of the drive unit 3 or the power supply unit 7 is opened, and the theft is caused by an artificial factor such as removal of equipment or a battery. Also, the control unit 6 detects this and notifies the manager, but in this case, the method of detecting theft includes when the installation position of the circuit breaker 1 is displaced, when the lid leading to the inside is opened, and the like. An abnormal signal is transmitted to the control unit 6.

An embodiment using the circuit breaker 1 of the present invention having the above configuration will be described. As shown in FIG.
When two breakers 1 are placed one each near the starting point and the end point across the road construction area, and when the road construction area is to be alternately driven on one side, as described above, the two barriers 1 The traffic information detected by the detection unit 5 is transmitted to the control unit 6 via the wireless communication unit 35, and the control unit 6 displays the start or stop display of the signal units 4 of both the circuit breakers 1 based on the traffic information. Simultaneously with the switching, the drive unit 3 is driven to open and close the blocking bar 2 by the arm 16 to control the traffic of a vehicle or the like. In this embodiment, the case where the circuit breaker 1 is installed at two places has been described. However, as in the case of construction over a three-way intersection or construction of a crossroad, it is installed at two or more places to perform traffic control. You may.

Further, as shown in FIG. 9, when vehicles are stopped one by one at a time at an entrance or exit of a factory and the vehicle is stopped, the circuit breaker 1 is installed at the entrance, and a signal is provided. When the detection unit 5 detects that the vehicle is temporarily stopped in front of the unit 4 and the blocking bar 2 according to the stop display, and the information is input to the control unit 6, the signal unit 4 is activated by a command from the control unit 6. At the same time as the start display is switched, the blocking bar 2 is raised and the vehicle enters the factory. At the same time, the signal section 4 is switched to the stop display, and the blocking bar 2 descends to block traffic.
Similarly, one by one, with a time interval, stops once and enters the factory.

The circuit breaker 1 of the present invention may take various embodiments other than those described above.
When an abnormality occurs in the circuit breaker 1, the abnormality is immediately notified to the manager, the cause of the abnormality is eliminated, and smooth traffic control can be achieved.

[0028]

As is apparent from the above description, the circuit breaker according to the present invention has a long bar-shaped blocking bar, a driving unit for opening and closing the blocking bar, a signal unit, and a signal unit. A detection unit that detects traffic such as a vehicle, and a control unit that controls a signal unit and a drive unit based on the traffic information from the detection unit.
A power supply unit that supplies power consumed by the drive unit, the signal unit, the detection unit, and the control unit, so that when the vehicle travels frequently, the travel time in the direction of travel of the vehicle is increased. The start display time of the signal section and the opening time of the blocking bar can be set long, and in the opposite case, the time can be set short, so that the vehicle can flow smoothly and the traffic control can be done smoothly. is there. Further, by setting various control methods of the control unit, efficient traffic control can be selected and performed.

Further, since the power supply unit is provided in the circuit breaker itself, it can be used even in a mountainous area where a transmission line does not pass near the circuit breaker. Furthermore, even when the transmission line is running, the time required for the preparation can be greatly reduced because the branching work is unnecessary.

Further, conventionally, a total of two circuit breakers are arranged one each near the starting point and the end point of the road construction area, and these two circuit breakers are connected and controlled by wiring. In addition to the drawbacks that wiring had to be performed across the road, there was a drawback that if the intervals between construction areas were long, the wiring would also need to be long. Since the device is equipped with a wireless communication unit, such wiring is not required, and there is an advantage that the equipment cost can be reduced and the preparation work can be greatly reduced. On a flat ground or the like, the distance between the two breakers can be up to several kilometers.

Further, when the voltage of the power supply section falls below the predetermined pressure, the supply of current to the drive section which consumes a large amount of power is immediately stopped to stop the opening / closing drive of the blocking rod, and the signal section is started and stopped. Since the power is consumed only for switching the stop display, traffic control can be performed for a predetermined time even in the power supply unit whose voltage is sufficiently reduced. In addition, since the motor is driven before the supply of the current to the drive unit to be cut off so that the blocking bar is raised, the traffic of the vehicle or the like is not obstructed. Further, since the information of the voltage drop is immediately notified to the manager, the power supply unit can be replaced while the power storage amount of the power supply unit is not completely consumed.

As a start or stop signal of the signal section, an LED is used.
In the case where is used, there is an advantage that the power is low and the life is long.

Further, when the control unit detects any abnormality such as a voltage drop in any one of the drive unit, the signal unit, the detection unit, and the power supply unit constituting the circuit breaker, and detects the abnormality, It has a communication control function that can immediately transmit the abnormal alarm to the person in charge of management via a wired or wireless telephone line, etc., so that it is possible to respond quickly to failures of circuit breakers, etc., and as a result, disruption of traffic of vehicles etc. is minimized. There is an advantage that can be suppressed.

Further, since the circuit breaker is provided with expensive parts such as a power supply unit such as a battery, a display unit composed of LEDs, a wireless communication unit, etc., in case of theft, By immediately reporting this to the manager by the communication control function, there is an advantage that human damage can be minimized.

Further, if the detection unit does not detect any traffic of the vehicle or the like for a predetermined time or more, if an abnormality alarm is started, a failure other than a voltage drop to the detection unit may occur. It is possible to know that an abnormality has occurred, such as a change in the direction of the circuit breaker due to contact with a vehicle or the like.
