Description

{TRAFFIC SIGNAL LAMP FOR DISPLAYING REMAINING TIME OF PEDESTRIAN LAMP AND STANDBY TIME OF PEDESTRIAN}

More particularly, the present invention relates to a traffic signal lamp capable of displaying a standby time as well as a remaining time such as walking on a pedestrian crossing installed on a pedestrian crossing.

A traffic light on the road is a traffic control facility that is operated by the power of electricity or people. It instructs or warns to take any designated movement for traffic such as vehicles or people. The functions of these traffic lights are to control conflicts between pedestrians and traffic including bicycles, to warn of possible hazards, to facilitate traffic flow, and to control traffic when crossing bridges or railway crossings. These traffic lights are collectively referred to as 300 mm (or 200 mm) diameter vehicles, such as walking lights, alarm lights and variable lanes, and also include traffic signal controllers, traffic lights, and other related facilities. define.

On the other hand, pedestrian traffic lights (hereinafter referred to as "walking") are generally installed on the pedestrian crossing. However, these walkers inform the pedestrians that the walking signal is being closed by flickering, but there are often people who walk on the pedestrian crossing in a short time because they do not know how long the pedestrian signal will be maintained in the flashing state. When the pedestrian enters the pedestrian crossing at the end of the pedestrian signal, the pedestrian stop signal is turned on as soon as the pedestrian enters the pedestrian crossing. As a result, the pedestrian stops at the pedestrian center line, and a traffic accident is very likely to occur.

Particularly, crosswalks crossing a general road, not an intersection, are often embarrassed because pedestrians enter a pedestrian crossing late because a vehicle signal comes in at the end of a pedestrian signal. It is difficult for the driver to know the position of the crosswalk at night or in bad weather, and it is difficult for the driver to predict the remaining time of the pedestrian signal.

In order to solve such a problem, Korean Patent Registration No. 10-655741, Korean Patent Publication No. 2012-7477, Korean Registered Utility Model No. 20-388734, Korean Patent Publication No. 2009-113085, And the Korean public utility model number 2010-4605, and the traffic signal indicating the remaining time, such as walking.

FIG. 1 is a view illustrating a traffic signal lamp indicating a remaining time of a walking light according to a conventional technique, and FIG. 2 is a block diagram of a traffic signal lamp showing a remaining time of a walking light according to a conventional technique.

1 and 2, a traffic light for indicating the remaining time of a walking light according to the related art includes a walking light 10, a walking assist device 20, a support 30, an embedded wiring 40, And a traffic signal controller 50. The walking light 10 includes a red walking light 11 and a green walking light 12. [

A traffic signal lamp for displaying a remaining time of a walking light according to the related art is largely classified into a traffic signal controller 50 for lighting an assist device 20 such as a walking light 10 and a walking light and a signal face thereof A pillar 30 is installed at a predetermined height on the ground and a walking light 10 for recognizing a traffic signal is installed on the pillar 30 coupled to the pillar 30 in a lateral direction.

In this case, the traffic light is operated by receiving power from a device called a traffic signal controller 50, and the walking light 10 and the walking assist device 20 are also operated from the traffic signal controller 20 to the buried wiring 40 , And the AC voltage is converted into a DC voltage to drive the walking light 10 and the walking assist device 20.

The traffic signal controller 50 is provided at an intersection and a pedestrian crossing to control a traffic light and includes a timer adjusting unit 51, a timer 52, a control unit 53, a power supply unit 54, and an LED driving unit 55 For example, a main control unit (MCU), a signal control unit (SCU), an independent device mounting unit such as an image detector, and an operator control unit A MMI (Man Machine Interface Unit) unit, an external device, a terminal board for processing input / output signal connection, and other auxiliary devices, but may be different depending on the purpose of use.

FIG. 3 is a diagram illustrating an example in which a walking assist device is implemented in the form of a symbol and a numeral in a traffic light indicating a remaining time of a walking light according to a conventional technique. Fig. 8 is a view for explaining the operation of the walking assistant device in a traffic light indicating time;

In the traffic light for indicating the remaining time of the walking light according to the conventional technique, the walking light 10 has a red human still shape 11 and a green person's walking shape 12 , And a symbolic pedestrian remaining time indicator 21 or a numerical pedestrian remaining time indicator 22 is provided as a walking assist device 20, as shown in Figs. 3B) and 3C) (10). ≪ / RTI >

For example, as shown in FIG. 3 b), the symbolic pedestrian remaining time indicator 21 displays the remaining time with the triangle decreasing, or as shown in FIG. 3 c) The remaining time indicator 22 can display the remaining time directly as a number.

4A and 4B, the gait assist device 20 displays the remaining time before the lighting changes from the green light 12 to the red light 11, and the pedestrian is not safe There is no need to guess when the green light 12 will change from green to red any longer.

That is, the symbol-type green display of the assistant device 20 such as the green walking light 12 flashes downwardly, and the symbolic green display of the assist device 20 such as the walking light 11 At this time, the green display is turned on by the triangular symbol display. At this time, when the red gait light 11 is turned on, the gait assistant device 20 does not display anything.

The gait assist device 20 according to the related art provides the walking time or the remaining time of the pedestrian and does not provide the pedestrian's waiting time.

5 is a view for explaining a case where a traffic signal indicating the remaining time of walking light according to the related art is installed at the intersection intersection.

Referring to FIG. 5, in the case of a traffic light indicating the remaining time of the walking light according to the conventional art, when the pedestrian enters the area R1 in the intersection such as the intersection, It is impossible to know whether any of the gait assist devices 20 is turned off in a state in which the red gait is turned on and it is not known whether any red gait or the like will be changed first due to a green walk or the like and accordingly the pedestrian can not recognize the A crosswalk or the B crosswalk It is impossible to decide which of the crosswalks to wait.

According to the traffic signal indicating the remaining time of the walking light according to the conventional technique, the pedestrian can not know the walking priority of the pedestrian crossing at an intersection such as an intersection.
