The present invention relates to Korean Patent No. 0329419 (Application No. 1999-0027862), Korean Patent No. 0572343 (Application No. 2003-0061271) and Korean Utility Model Registration No. 0289229 (registered by PCT / KR2006 / 002228). Application No. 2002-0018926) is a continuation in part.

According to the present invention, in the pedestrian crossing traffic light system, a conventional traffic light system, that is, a pedestrian traffic light, a stop light, a pedestrian signal remaining time display device and a pedestrian remaining time display device in one LED (Light Emitting Diode) light panel type traffic light It is designed to be combined to provide a technology to drastically reduce the installation and operation costs of pedestrian crossing traffic lights.

Secondly, as a means of generating voice signals, both visually impaired people and pedestrians can listen to the remaining time together by voice, provide information or advertisements to crosswalk users using LED panels, or add sensors to recognize the presence of crosswalk waiters. To solve the problem of unnecessarily blocking the flow of traffic.

In addition, when the above technical concept is applied, a traffic light composed of one multi-color LED element provides a useful signal system for displaying a stop signal, a progress signal, and up to the remaining time of each signal.

The conventional pedestrian crossing traffic light system has a problem that the installation cost is high by separately installing the stop light, the pedestrian signal and the pedestrian signal remaining time indicator, and the acoustic oscillator for the disabled. Dissemination and installation of the acoustic oscillator has not been made smoothly has caused inconvenience to users.

In addition, the conventional method has a problem of causing pedestrians to wait for an accident or to cross the road because the pedestrians cannot predict when the signal will be changed, and there is no means for delivering information to the pedestrians waiting for the crosswalk signal.

In addition, the conventional walking signal identification for the visually impaired is a sound signal method has caused confusion in determining whether the visually impaired people cross the crossover because the disabled can not predict the remaining time of the walking signal.

In addition, when a failure occurs in the conventional pedestrian crossing traffic light system, there is a problem that the failure is left for a long time because the self-diagnosis is not performed by the management department and remotely alarmed by wire or wireless communication.

In addition, there is a problem that the traffic flow is unnecessarily blocked by switching to a pedestrian signal even though there is no pedestrian due to the failure to automatically identify the presence or absence of pedestrians in the crosswalk of two-way roads.

In addition, in the crosswalk traffic light system in front of the school, there was a difficulty in relying only on the traffic lights because the receptionist signaled the driver with a hand signal and induce pedestrians to cross safely.

In addition, the conventional traffic light has a problem that causes traffic accidents such as speeding at the intersection because the cost is expensive and the information on the remaining time of the signal change is not available to the drivers because the red traffic light and the green traffic light are separately configured. .

In order to solve the above problems, the present invention consists of a conventional LED traffic light system consisting of a plurality of traffic lights in one LED (Light Emitting Diode) electronic sign system, that is, pedestrian signal display and stop signal Display and pedestrian signal remaining time display and pedestrian signal remaining time display by one LED display board, four devices (pedestrian signal light, stop signal light, pedestrian signal remaining time display device, sound signal oscillator) It provides a technology that reduces the installation cost of pedestrian crossing traffic light system to less than 1/2 of the existing method.

In addition, by adding an address means for addressing the CPU of the traffic light, the LED display board of the traffic light can display information on national emergency disaster warning messages, announcements, advertisements, etc. as still images or flowing forms of static images or numbers. Provide a useful means.

In addition, the sound signal for the visually impaired is composed of a voice signal and the remaining time is generated as a voice signal such as "remaining time 40 seconds" "residing time 35 seconds" "remaining time 30 seconds" and the like. It provides a means for knowing the remaining time. In particular, the general pedestrian can listen to the remaining time by hearing even if the visual remaining time display device is not continuously stared during the crossing, thereby providing a service for making pedestrians comfortable.

In addition, when the address and communication means are added to the crosswalk traffic light system, the traffic light system self-diagnoses itself to alert the failure by wire or wireless telecommunication means as well as prompt A / S, and remotely control each traffic light system by address. Or provide technology that can be managed.

In addition, the CPU of the pedestrian crossing controller identifies whether or not there is a pedestrian waiting in the waiting area of the pedestrian crossing, and solves the problem of unnecessarily blocking traffic flow by changing the pedestrian crossing traffic light even though there is no pedestrian.

In addition to the traffic lights in the lanes of crosswalks, in addition to traffic lights, the stop line flashes or flashes, providing a useful means of double warning to alert the driver in sensitive crosswalks, such as in front of the school.

In addition, the above technology is used as a traffic light to provide a traffic light system that drastically reduces traffic accidents due to speeding at an intersection by notifying the driver of the stop signal, the progress signal and the remaining time of each signal with one LED traffic light.

Hereinafter, with reference to the accompanying drawings will be described the system configuration of the present invention and its effects and effects for achieving the above object.

Fig. 1 is a block diagram showing the system configuration of the present invention, and Figs. 4 to 7 are exemplary views showing the configuration of the LED signal lamp of the present invention. As shown in Figs. 1 and 4, the present invention receives signal information data output from the external traffic signal control means 101, flashes the stop signal and the walking signal, calculates the remaining time of each signal, and displays the remaining time. Control means 102 for dispensing a number of image graphics or for a specific number of seconds and for centrally controlling each function of the system; Comprised of multi-color LED all-optical panel, it displays pedestrian image and pedestrian remaining time when pedestrian signal according to control signal of control means, and pedestrian crosswalk LED signal which displays both stop signal image and stop signal remaining time when stop signal. 120; According to the control signal of the control means, the stop signal and the remaining time of the stop signal are displayed in red numbers, letters, or figures in the case of the stop signal in the crosswalk LED signal lamp. It is composed of LED control means 105 for displaying in green numbers, letters, or figures, dividing the remaining time of each signal into image graphics or numbers, and driving the shape or operation of each image.

When the voice signal oscillation means 103 which oscillates as a voice signal is additionally configured to the control means 102 as the remaining signal of the pedestrian signal, the remaining signal of the pedestrian signal is notified by voice so that the pedestrian signal which is useful to both the disabled and the general pedestrian is left. Provide a time notice.

When additionally configuring the motion / image detector means 115 that identifies the presence of a pedestrian waiting in the signal waiting area to the control means, the traffic control means identifies the presence of waiting for walking and prevents the control means from changing the signal when there is no pedestrian waiting. By controlling 101, the problem of unnecessarily blocking the flow of traffic is eliminated.

In addition, when the LED sign bottle 130 is buried in the lane approaching the pedestrian crossing at the pedestrian crossing, and the track is constructed on the control means, the driver is alerted by a light signal or a flashing signal of the LED sign bottle. Provides safe warning means to protect pedestrians from sensitive crosswalks.

When the address means 116 for addressing the control means and the communication means 114 for providing wired or wireless communication between the control means and the external communication means are additionally configured, remote control of each LED signal lamp is performed by an external host computer. Or provide a means to manage it.

Wired or wireless communication means 201 for transmitting and receiving data between the external display board control host computer as shown in Figure 2 to separately configure the message display means on the upper or lower portion of the LED display board of the present invention in the above configuration And memory means 206 for storing message data signals, character generator means 207 for oscillating characters or figures to be displayed on the display board 205, and controlling or speeding up letters, numbers or figures in the form of flowing on the display board. And LED control means 203 including driver means 204 for controlling the size and movement, address means 208 for specifying the address of the electronic display board, and display control means 202 for controlling the above means. do.

First, the signal system of the crosswalk will be described first. As shown in FIG. 1, when the control means 102 receives the signal change information signal from the external traffic signal control means 101, the CPU of the control means stops walking and stops. The remaining time of each signal is calculated based on the flashing time between signals. At this time, if the remaining time display is composed of a plurality of LED modules, the remaining time is divided by the number of modules, and when the signal is changed, the remaining time is displayed by turning on several LED modules at once and then turning off sequentially. When displaying in unit number, the remaining time is displayed in the unit of second time interval.

When the control means transmits a control signal to the LED control means 105, the LED control means lights up the LED constituting the stop signal display image in red and at the same time blinks the LED by the red signal remaining time setting means 108 to display the remaining time. The time display means 109 of numbers or figures displays the remaining time of the prohibition of pedestrian time as a red LED.

When the control means 102 receives the walking signal from the external signal controller, the LED on the walking signal display image lights up in green in the same manner as described above, and at the same time, the LED is blinked by the green signal remaining time setting means 111 to indicate the remaining time. The remaining time is indicated by the green LED by the time display means 113 of the figure.

On the other hand, when the traffic light is manually controlled, the external traffic control means transmits the manual signal control information to the control means 102. In this case, the control means controls only the walking signal and the stop signal and does not display the remaining time of each signal. Control or flashing.

As shown in FIG. 4, when the LED panel is configured with dual green and red LEDs, the remaining time display unit is left or right on the left or right side of the dual LED display unit constituting the stop signal and the walking signal image. It is composed of LED and displays with figure or number of same color as pedestrian signal or prohibition of pedestrian signal, and realizes each function of stop light, pedestrian signal, stop signal remaining time indicator and pedestrian signal remaining time indicator as one LED signal lamp. will be.

In addition, as shown in FIG. 5, in the configuration of the LED, the green LED constituting the walking signal and the red LED constituting the stop signal are composed of monochromatic LEDs respectively, and the remaining time display LED selectively emits green and red light. Dual) It has the same effect even if it is configured as LED and displays the remaining time by numbers or figures.

However, in the current LED technology of Figure 4 or 5, the brightness of the multi-color LED is lower than the brightness of the single-color LED, so when the brightness can not meet the country-specific brightness standards, it can be configured as a single color LED instead of dual LED, In this case, as shown in Fig. 8, the monochromatic LEDs constituting the image of the number or figure are arranged in an intersecting manner, and the red and green images may be the monochromatic LEDs in the same area.

The image of the stop signal or the pedestrian signal is composed of an LED figure or a character (STOP) according to the national standard, such as a standing image, a walking image, a palm image, an arrow image, or a multiplication table (×) image. , WALK, etc.) is the same action and effect.

The remaining time display is displayed in the number of seconds, or the number of figures such as inverted triangle, inverted bridge, bar or arrow, and walking signal or stop as shown in FIG. The same effect can be obtained by arranging the image of the walking signal or the stop signal on the left or right side based on the image of the signal, or separately configuring the left or right side signal based on the remaining time display as shown in FIG.

In addition, as shown in FIG. 7, the red and green dual LEDs constitute an image of a pedestrian signal or a prohibition of pedestrian signal at the center of a traffic light, and a bar or figure of a time display form of a clock is formed of LEDs around the perimeter. If a bar or figure is composed of LEDs, the remaining time can be displayed by changing the number of bars or figures. At this time, if the time display is divided into 4 or 6 parts, the bar or figure of each point is configured so that it does not turn off until the remaining time is changed or displayed in flashing form. If the LED color of the remaining time display bar or figure is composed of colors other than red and green, the same effect is obtained.

In the present invention, one LED panel constituting the signal lamp is composed of red and green dual LEDs which are displayed as both red and green signal lamps. When configured with LEDs, a single LED traffic light provides a useful means of displaying the green and red lights together with the remaining time of each signal numerically. Such traffic lights are not only pedestrian crossing traffic lights but also all red traffic lights on the road. Integrating the traffic light into one, or in combination with the configuration of Figure 2 provides a useful means to display the LED information in flowing form in all or a portion of the traffic light in the event of an emergency.

This signal is used to display the red and green signals, the remaining time of the red signal, and the remaining time of the green signal together in one signal lamp, thus greatly reducing the installation cost of the traffic light. Therefore, it is possible to provide a useful means for the driver or pedestrian to increase the numerical display of the signal change time to predict the remaining time from a long distance.

In addition, by applying the above technology, it can be configured to display the remaining time in various LED traffic lights consisting of the existing monochromatic LED, in this case, by displaying the remaining time has the effect of predicting the remaining time of signal change to pedestrians and drivers have.

In addition, as shown in FIG. 1, the acoustic signal for the visually impaired includes a voice signal oscillator, an amplifier, and a speaker 104 in the system of the present invention. By configuring the remaining time in a specific time unit such as 40 seconds remaining, 35 seconds remaining, 30 seconds remaining, etc., the remaining time can be predicted by the visually impaired. In addition to the existing visual display, it provides a useful means of hearing the remaining time by hearing.

Even if the sound signal oscillating means oscillates a signal of dual tone of dual tone instead of voice signal and configures the visually impaired person to predict the remaining time at the oscillation interval.

As shown in Figs. 2 and 6, the display control means 202, which is inherent to the separate LED light panel 205, and the wired or wireless communication means 201 between the address setting means 208 and the external control device. When the LED control means 203 is configured to remotely control the LED light panel with an external host computer, the message data signal to be displayed is received for each address, stored in the memory means 206, and the LED control program is transmitted as an indication signal. The ability to display messages, information, or advertisements in a flowing form can be implemented.

In addition, in the above configuration, a separate LED control module programmed to implement a separate advertisement or message on the LED panel in a variety of patterns without configuring the communication means of the external communication in a removable pattern when the configuration for adding information to the module Programmed advertisements or messages are displayed repeatedly and repeatedly in a specific pattern. If you want to change the contents, you can change the contents and patterns of the display by replacing the module.

In addition, as shown in FIG. 1, when a failure or malfunction occurs in the traffic light system in the system of the present invention, the CPU of the control means 102 self-diagnoses it with a sensor means and a failure detection program to perform a wired or wireless communication means 114. It can alert the host computer of the management department to provide a means to quickly solve the malfunction problem caused by the failure.

In particular, the above system additionally configures a specific short-range long wavelength wireless transmission / reception means to transmit information on the abnormality of the system recognized by the CPU of the system when the system administrator's wireless transmission / reception apparatus approaches within the communication distance. By simply patrolling the road, the manager provides technology that can automatically identify whether there is a problem with the pedestrian crossing traffic light system, in which case the Bluetooth communication standard can be used.

In addition, an image detector for detecting the presence of a pedestrian waiting with a digital camera, a motion detector means for detecting the movement of an object, infrared (IR) detection means for detecting the presence of an object, a UV sensor, etc. When the control means 102 is additionally configured, the detector means can compare the data sensed by two or more means individually or by the CPU of the control means to determine the presence of a walking waiter. Even though there is no pedestrian waiting by transmitting the signal data for to the CPU of the traffic control means 101, the traffic control means controls the change of the signal or does not directly display the walking signal or the remaining time of each signal. And the problem of existing technology to cut off traffic flow unnecessarily as it can solve the problem of changing the crosswalk traffic light. Solve the point.

In this case, various sensor means may be additionally configured in the CPU of the control means 102, and the same effect may be achieved even if the program is reduced to compare with the data of the presence or absence of pedestrians recognized by the digital camera.

In particular, such a pedestrian identification device is a system that can be usefully applied to the installation of pedestrian crossing traffic lights only for pedestrians on two-way roads, and pedestrians do not cross the road in the middle of the road in accordance with the development of image detector technology. If not (especially for people with disabilities), Image Detector provides a useful technique that can be configured to recognize and extend the signal change time.

In addition, when a plurality of LED beacons are embedded in a single row or a plurality of rows in connection with a vehicle stop line at a crosswalk of a lane, and connected to the control unit 102 or the green LED display unit 111, the control unit controls the control unit. At the time of walking signal, the power of the LED beacon can be turned on to warn the driver to be careful to enter the crosswalk with the LED light signal of the beacon.

In this case, the color of the LED can be configured as red or yellow light, and can be configured to be continuously turned ON or blinking, and provides a useful warning means especially on roads with frequent crosswalks or crosswalk accidents in front of the school.

In particular, by notifying the visually impaired by the voice signal, the pedestrian crosswalk accident can be reduced dramatically.In addition, the pedestrian can display the remaining time as well as the remaining time of the pedestrian signal with one device. When the stop signal, the function of the LED signboard to notify the announcements or advertisements to provide a means to solve the boredom and deliver information to people waiting for the signal has a working effect compared to the existing prior art Significantly improved and advanced.

In addition, by assigning an address to each crosswalk traffic light and configuring a wired or wireless communication means, it is possible to self-diagnose the failure of the traffic light system by remote communication means and quickly A / S, and to remotely control the traffic light system of each crosswalk by address. It provides a useful technique for controlling or presenting a message signal.

In addition, advertisements can be displayed as well as announcements and information, so the advertisers can install the crosswalk traffic light system without any national budget (as advertising revenue), so that the national crosswalk traffic light system can be installed free of charge nationwide. As a result, it is possible to greatly reduce the national budget in this field, and it is possible to quickly solve the crosswalk traffic light system in the area where the pedestrian traffic light system is not formed due to the budget relationship, thereby dramatically reducing the traffic accident of the crosswalk.

In addition, since the signaling system can recognize the presence of pedestrian waiting on the crosswalk and control the operation of traffic lights, it is useful to solve the problem of unnecessarily blocking the flow of traffic by changing the signal even though there is no pedestrian waiting. to provide.
