Description

TRAFFIC SIGNAL LAMP FOR INSTALLING OVER INTERSECTION}

The present invention relates to a traffic light, and more specifically, to a driver of a vehicle, the remaining time display device of a traffic light that can prevent a traffic accident by displaying a signal remaining time before the signal of the traffic light is changed to the next signal. And to a method.

Due to the exponential growth of vehicles, road traffic conditions are deteriorating. In order to improve the road traffic situation and smooth communication, precise control of traffic lights is required. The traffic signal controller currently used in Korea installs one traffic signal controller at one intersection, and installs a signal light main body including a plurality of traffic lights attached thereto at a constant height from the ground, so that the driver who rides in the vehicle can easily signal. It is configured to identify it easily.

The conventional traffic signal controller connects a plurality of traffic lights installed at each intersection with a traffic signal controller using wires, and controls each traffic light by setting an automatic or manual mode by a traffic management agent. It can be seen that the traffic lights are provided with two, three or four (blue, yellow, red or bypass arrows) depending on the state of the intersection or road.

However, in the traffic signal controller as described above, the driver can visually recognize the current state such as the progress, stop, and right turn of the traffic light, but it is difficult to predict the next state of the traffic light. That is, the current traffic light state (e.g., a blue signal) can be clearly seen by visually confirming the current on / off state of the traffic light installed in the traffic light, but the blue signal is the next signal after some time has elapsed. For example, yellow or red) was not known exactly.

To explain this in more detail, the traffic lights are typically provided with all four traffic lights red, red, yellow, arrow, and green from the left, red and green, or only red, yellow, green, etc. The installation state of the traffic light changes depending on the state of the intersection.

At this time, the signal is changed from blue to red or yellow while the vehicle continues through the signal waiting line in the state of the green signal which is the progress signal of the vehicle. Therefore, in progress, the vehicle was suddenly stopped in the middle of the intersection to obstruct traffic flow, or the vehicle on the signal waiting line of another road that received a straight signal suddenly started to collide with each other while the vehicles crossed.

In addition, when a vehicle is started from a red light, if a driver insists that the driver is in yellow, the police will determine the penalty and penalties at the discretion of the traffic police, but this is very subjective. There are a lot of problems because they are involved.

The present invention was devised to solve the above problems, and the object of the present invention is to accurately recognize the remaining time of the driving direction signal when driving a driver near the intersection, and to drive the traffic at the intersection with an accurate judgment of whether or not to enter the intersection. It is to provide a traffic light installed at the intersection formed by increasing the brightness and size so that the distant user can identify the remaining time until the red and green lights are turned off so as to contribute to the prevention of accidents.

Another object of the present invention is to display the remaining time when the traffic light is turned on to the driver and to attract attention to the remaining time so that the display is brighter when the period is shortened to prevent the severe tangle caused by the excess of the stop line. It is in one place.

The present invention relates to a traffic light installed at an intersection, and includes a timer for indicating a time when the power is applied to generate a clock signal to control the blinking of each traffic light, and a time during which the red light of the traffic light is turned on. After detecting the elapsed time from the timer, the number is decreased by 1 from the time while the red light is on, and it is displayed up to '0' and the time when the green light of the traffic light is on is recognized. Display detects the elapsed time from the timer and decreases the number one by one from the time when the green light is turned on, and displays up to '0' and the LED display unit adjusts the intensity of the number or luminance. LED driver to send a signal to the LED driver, and a control signal by sending a control signal to the LED driver By is composed of a microcomputer for controlling so that the intensity of a number, a brightness adjustment on the LED display section.

Hereinafter, with reference to the accompanying drawings will be described in detail the traffic lights installed in the intersection of the present invention.

1 is an installation diagram showing an embodiment in which a traffic light is installed in the intersection according to an embodiment of the present invention.

Referring to Figure 1, the installation position of the LED display unit 150 for displaying a number on the upper portion of the traffic light 100 is installed in any position that the driver can easily identify the character indicating the remaining time It is also possible. Among these, in order not to disperse a driver's eyes, it is most preferable to install in the vicinity of the traffic light 100.

In FIG. 1, four traffic lights are displayed in which red lights, yellow lights, arrow lights, and green lights 110, 120, 130, and 140 are emitted from the left, respectively. Thus only two or three traffic lights can be installed.

The installation state of these traffic lights is all controlled by the present invention. That is, in the present invention, first, which signal lamp is operated and only the set time corresponding to the activated traffic lamp is displayed so that it is displayed. For example, even if only two traffic lights of red and green are connected, the time set in another traffic lamp is displayed. It can be seen that it is impossible. Character display of the LED display unit 150 is configured using a plurality of high-brightness LED, it may be larger in size according to the driving situation. The LED display unit 150 and the LED driver 152 configured as described above are controlled by the controller 160 so that the signals are controlled without confusion so as to display the remaining time during which the red light 110 and the green light 140 are turned on. Let's do it.

However, since drivers should check the numbers at a long distance from inside the vehicle, it is preferable to use the size of the LED display unit 150 to be approximately 450mm in width and length, respectively. In addition, when the red light 110 is turned on, the LED display unit 150 displays the remaining time with a red LED, and when the green light 140 is turned on, the remaining time is preferably expressed in green. . Therefore, the LED display unit 150 is preferably composed of green and red LEDs to implement two or more colors.

In addition, when the remaining time of the signal of the red light 110 or the green light 140 is 5 seconds remaining, the controller 160 increases the luminance of the LEDs configured in the LED display 150 through the LED driver 152, respectively. The output is configured to allow the driver to concentrate on the traffic light and LED display unit 150 to drive more.

The control unit 160 is installed in the middle of the support member for supporting the traffic light 100, for example, 3.5m high from the ground so as not to be affected by pedestrians, and installed in the holding part by a special vehicle or an overload vehicle. To prevent breakage.

2 is a block diagram illustrating a block configuration of a traffic light installed at an intersection according to an embodiment of the present invention.

Referring to FIG. 2, a traffic light installed at an intersection may be adjusted according to the timer 164. First, the power 180 is applied. The central control unit 170 installed on the roadside to control a plurality of traffic lights is loaded by receiving the power 180.

The timer 164 configured in the controller 160 generates a clock signal to enable the microcomputer 162 to control the blinking of each signal lamp.

For example, when the period during which the red light 110 is turned on is set to 45 seconds by the central controller 170, the microcomputer 162 recognizes the time when the red light 110 is turned on and then elapses from the timer 164. Detects the time and displays the number from the Arabic numerals of 45 to 1 by sequentially decreasing the number by one, and then lights up other signals such as the yellow light 120.

The yellow light 120 is a signal indicating a warning, detour, or waiting light, so the time from the yellow light point to the end of the yellow light is short. Therefore, when the yellow light 120 is turned on, the number is not displayed on the LED display 150. Do not However, if necessary, the number may be gradually decreased from the time when the yellow light is turned on, for example, from '5'.

Since the arrow light 130 is often displayed together with the green light, for the description of the arrow light 130, the remaining time is not displayed on the LED display unit 150.

The green light 140 is a driving signal of the vehicle. For example, when the driving signal of the vehicle is set to 45 seconds by the central controller 170, the microcomputer 162 recognizes the time when the green light 140 is turned on, as in the red light 110, and then elapses time from the timer 164. Detects and displays the number of '45' from Arabic numerals in order from '45' to '0', and then turns on other signal lights, such as red light 110.

The power switching LED driver 152 transmits a signal to the LED display unit 152 to be operated by the control code from the microcomputer 162. That is, in the above description, the microcomputer 162 controls the LED display unit 150 to display the numbers. However, the LED driving unit 152 generates a signal to substantially display the numbers and the like. The microcomputer 162 transmits a control signal to the LED driver 152 to display the number by the control signal.

As described above, according to the present invention, it is possible to reduce the occurrence of a traffic accident by displaying a signal operation state of a traffic light with time to give a driver adequately to cope with a signal change of the traffic light.

In addition, the traffic light of the present invention provides the driver with psychological stability and predictable driving time by three-dimensionally illustrating the time to be changed in the intersection traffic light red and green to establish traffic order on the intersection and prevent traffic accidents. It has an effect.

In addition, the brightness of the traffic light of the present invention has the effect of preventing traffic accidents due to signal unclearness, such as the sun phenomenon by realizing and displaying the color using the ultra-low power high-brightness LED bulb.

In addition, the present invention prevents sudden braking and sudden start by pre-exemplifying the remaining time to the driver, which can greatly contribute to the drastic reduction of social indirect capital such as fuel consumption reduction, and the prevention of air pollution caused by tire wear and sulfur dioxide emissions. It works.

In addition, by implementing only a display unit and a control unit in the existing system of the present invention to implement a system that allows the driver to predict the flashing time of the corresponding traffic light, there is an effect that can be implemented at a lower cost.
