DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic signal, and more particularly, to a portable traffic signal having a traffic blocking function.

[0002]

2. Description of the Related Art Conventionally, traffic is regulated by road construction and the like, and when performing alternating traffic, a signboard or a traffic light is provided to inform a pedestrian that construction is in progress.

[0003] For example, in the case of a road construction, the contents of the construction, the construction period, the contents of traffic regulation, and the like are described on the signboard, and the contents of the description are rewritten by a worker according to the construction contents and the situation of the construction. Can be

[0004] In addition to a standing signboard, a traffic light for regulating traffic on a road is installed. This traffic light displays a green signal and a red signal to instruct a driver such as an automobile to alternately pass.

[0005] Alternatively, there is a case where an operator performs a traffic guidance instead of a traffic light. When workers give traffic guidance,
The driver is instructed to proceed or stop by using a flag.

Therefore, a driver of an automobile or the like confirms the construction contents, the contents of traffic regulation, and the like using a standing signboard, and travels according to a signal or an instruction from a worker.

[0007]

However, in the conventional traffic signing by a standing sign, a traffic light or an operator, it is necessary to separately arrange the standing sign and the traffic light or the worker. In addition, the driver had to confirm these standing signs and traffic lights separately before passing.

In the traffic guidance by workers,
It was difficult for the operator to communicate the intention of the operator.

[0009] Further, the contents of the signboard must be rewritten by a worker's hand, resulting in a decrease in work efficiency.

[0010] An object of the present invention is to provide a traffic signal device capable of displaying the details of regulation and performing traffic guidance safely when traffic regulation is performed by road construction or the like.

[0011]

When the operation changeover switch is set to “automatic”, the function unit 2 controls the information display device 40 and the like according to a predetermined instruction signal from an automatic operation unit 31 described later. When the operation changeover switch is set to “manual”, the information display device is controlled according to an instruction signal from a manual operation unit 32 described later or an instruction signal transmitted from the wireless transmitter 3 via the wireless reception unit 10. 40
And so on.

The operation unit 30 includes an automatic operation unit 31 and a manual operation unit 32. When the operation switch is set to "automatic" by an operator, the automatic operation unit 31 is operated.
Outputs an instruction signal for instructing the control unit 20 to perform an automatic operation. When the operation changeover switch is set to “manual”, the manual operation unit 32 outputs an instruction signal to the control unit 20. The instruction indicated by the instruction signal is input by an operator from an operation key (not shown) of the manual operation unit 32 or the like.

The information display device 40 includes the LED display unit 4
1, when a display control signal is input from the control unit 20, the content instructed to be displayed by the display control signal is changed to L.
It is displayed on the ED display unit 41.

The information display device 40 stands up when the traffic light 1 is in use and displays information. When the traffic light 1 is not in use, the information display 40 may be stored by folding it back. (See FIG. 2). For this reason, the traffic signal 1 is easy to transport and store.

Further, at the upper end of the information display device 40, a rotating light is provided to alert the driver to the presence of the traffic light 1 and the like.

The two-position type traffic signal 50 includes a lens unit 51
, And the lens unit 51 has a red light and a blue light. The two-position signal 50 is connected to the control unit 2
When an operation control signal is input from 0, a red light or a blue light is turned on according to an instruction by the operation control signal.

The circuit breaker 60 is composed of a block rod 61 and a sign board 6.
2, and one end of the blocking rod 61 is attached to the main body of the circuit breaker 60 so as to be rotatable. In addition, a sign plate 62 is provided at the other end of the blocking rod 61, and when an operation control signal is input from the control unit 20, the blocking rod 61 moves up or down.

At this time, when the operation control signal input from the control unit 20 instructs the turning on of the red light of the two-position type traffic light 50, the blocking rod 61 is raised and the sign board 62 blocks the path of the passing vehicle. I do. Thereby, in addition to the lighting of the red lamp in the two-position signal 50, the driver is instructed to stop.
When the operation control signal input from the control unit 20 instructs to turn on the blue lamp of the two-position type traffic light 50,
1 descends, and the sign board 61 is stored in the sign storage box 70. As a result, in addition to the lighting of the blue light in the two-position type traffic light 50, the driver is notified of the traffic permission.

The blocking rod 61 has a central portion made of a buffer material or the like. Therefore, when the blocking rod 61 or the sign board 62 comes into contact with a passing vehicle, the blocking rod 61 is flexibly bent at the buffer portion at the center of the rod, and the blocking rod 61 or the traffic signal 1 can be prevented from being damaged.

The sign storage box 70 is provided with a sign board 62 when the function unit 2 indicates that the passage is permitted and the blocking rod 61 is lowered.
To store.

The sign storage box 70 has an arrow-shaped LED display unit 71 on the front surface. The arrow-shaped LED display unit 71 is composed of a green LED arranged in a large arrow shape.
In addition, the driver is given permission to pass.

When the operation changeover switch is set to "manual" in the control unit 20 of the function unit 2, the wireless transmitter 3 performs the same instruction as the instruction input from the manual operation unit 32 by the operator. Is transmitted to the functional unit 2 as a wireless signal. Note that the switching of the operation changeover switch between “automatic” and “manual” may be performed from the wireless transmitter 3.

Next, the operation will be described. First, a case where the operation changeover switch of the function unit 2 is set to “automatic” will be described.

When the operation changeover switch is set to "automatic", an operator sets a switching time between a red signal and a blue signal by an operation time setting section (not shown) provided in the automatic operation section 31.

When the traffic signal 1 is a red light, that is, when the function unit 2 indicates a stop instruction, the operation control signal indicating the red signal is transmitted from the control unit 20 to the two-position signal 50, the circuit breaker 60, and the arrow. Output to the LED display unit 71. Then, the two-position signal 50 turns on the red light and the circuit breaker 60
Raises the blocking rod 61 and the sign plate 62 to block the path of the passing vehicle. At this time, a display control signal in the case of a red signal is output from the control unit 20 to the information display device 40.

Then, the information display device 40 informs the driver that
Information in the case of a red light such as “waiting time” (for example, “Please wait about 5 minutes until the signal turns green.”) Is displayed on the LED unit 41. As the waiting time, the remaining time excluding the elapsed time from the time set in the operation time setting unit is displayed (see FIG. 3A). When the time set in the operation time setting unit elapses, the traffic signal 1
Shifts to a green light.

When the traffic signal 1 is a green light, that is, when the function unit 2 indicates that the traffic is permitted, the operation control signal indicating the green signal is transmitted from the control unit 20 to the two-position signal 50, the circuit breaker 60, and the arrow-shaped LED display unit. 71. Then, the two-position signal 50 turns on the blue light and the circuit breaker 60
Lowers the blocking rod 61 and stores the sign board 62 in the sign storage box 70. The arrow-shaped LED display unit 71 emits a green LED to instruct the driver to permit passage. Further, at this time, a display control signal in the case of a green light is output from the control unit 20 to the information display device 40.

Then, the information display unit 40 displays information in the case of a green light (for example, “Under construction. Please pass it carefully.
(B)). Then, when the time set in the operation time setting unit elapses, the traffic light 1 shifts to the red light again, and thereafter, similarly, the green signal and the red signal are alternately displayed.

Next, a case where the operation changeover switch is set to "manual" will be described. When the operation changeover switch is set to "manual", an operator manually switches the traffic light 1 to a red light or a green light. The switching between the red signal and the blue signal is performed by the operator directly operating the function unit 2 or remotely operating the wireless transmitter 3.

When the traffic light 1 is switched to a red light by an operator, an operation control signal indicating a red signal is output from the control unit 20 as in the case where the operation changeover switch is "automatic". The two-position traffic light 50 turns on a red light, and the breaker 60 raises the blocking rod 61 and the sign plate 62 to block the path of the passing vehicle. At this time, a display control signal in the case of a red light is output from the control unit 20, and the information display device 40 outputs information (for example,
"Please wait until the signal turns green.") Is displayed.

Next, when the traffic light 1 is switched to a green light by an operator, the operation changeover switch is set to "automatic".
As in the case of the above, the operation control signal indicating the green signal is output from the control unit 20, the two-position type traffic light 50 turns on the blue light, the breaker 60 lowers the blocking rod 61,
While storing the sign board 62 in the sign storage box 70,
The arrow-shaped LED display unit 71 emits a green LED. At this time, a display control signal in the case of a green light is output from the control unit 20, and the information display device 40 displays information in the case of a green light (for example, "Under construction. I ’ll call you. ”).

The traffic signal 1 repeats the above operation every time the operator switches between the red light and the green light, and indicates a stop instruction or a traffic permission, respectively.

As described above, the traffic signal 1 in the present embodiment uses the information display 40, the two-position signal 50, and the arrow-shaped LED display unit 71 to display information such as traffic regulation contents and waiting time and signal display. Can be confirmed at the same time.

Therefore, the driver confirms the traffic signal 1 and obtains a signal indicating a traffic permission and a stop instruction,
It is easy to grasp the information on traffic regulation, and the time to diverge the line of sight from the front is shorter than when checking the sign and the signboard indicating the information on traffic regulation separately, so that safer driving is possible. Become.

Further, in the case of a red light and a green light, when the blocking rod 61 of the circuit breaker 60 and the sign board 62 are lowered or raised, the instruction to proceed or stop is transmitted to the driver without fail. Safety is improved.

Further, in the case of a green light, the arrow-shaped LED display unit 71 emits light, so that a large arrow is displayed and the driver is permitted to pass.
It can be easily grasped that it is a green light.

Since the traffic signal 1 can be operated from a remote place by the wireless transmitter 3, the operator can operate without having to move to the place where the traffic signal 1 is installed. Therefore, the work efficiency can be improved.

The information display device 40 can display the traffic regulation contents by inputting or selecting the display contents with the operation unit 30, so that there is no need to write the information on a signboard or the like by hand, thereby improving work efficiency. Can be achieved.

Further, the information display 40 is a traffic signal 1
When the traffic light 1 is not in use, it can be folded down and stored as necessary, so that the traffic signal 1 can be easily transported and stored.

In this embodiment, the sign board 62
In the above description, a stop instruction sign is attached, but a sign or the like for displaying other information (for example, a flag indicating "stop", another regulation sign, or the like) may be attached.

In the automatic operation, the switching between the red signal and the green signal is described as being performed in accordance with one time set by the operation time setting unit. However, when the traffic volume from one side of the construction section is large, the red signal is switched to the red signal. The traffic light and the green traffic light may be set to have different times so that traffic from one side of the construction section is not congested.

According to the present invention, as the traffic regulation information to be provided by the whole traffic signal, the display contents of the signal display means, the blocking operation of the blocking means, and the display information of the information display means do not become inconsistent display states. Therefore, there is no confusion in the provided information, and consistent and highly secure traffic control can be achieved. And since the whole apparatus can be easily made compact at the time of storage, handling becomes easy and transportation becomes easy.
