Description

Technical field to which the invention belongs

  The present invention relates to a signal display technique related to a traffic control system, and as a result, relates to a signal display technique for connecting a signal lamp for displaying three colors of signals on a display surface of one lamp to a smooth display method.

  In a conventional one-lamp type signal lamp device, a light source color is condensed by a convex lens to perform a coloring operation, and a red light emitting diode (hereinafter, referred to as a red light emitting diode) is displayed on a display surface in the same frame in which no more than 27 three-color light sources are stored. LED), yellow LED, and green LED are arranged in order, and color operation is performed for each frame by alternation (Patent Document 1). In addition to the technology on the left, each color LED is arranged and an auxiliary signal is combined with a signal lamp. Wavelength conversion occurs when the plate is irradiated with the light to be displayed in the lamp (Patent Document 2), blue LED, and blue LED light. Thus, a resin plate containing fluorescent dyes for displaying each color is used in combination with the LED, and a technology (Patent Document 3) that enables red, yellow, and blue signal operations with a single signal lamp, and a large number of three-color LEDs. A technology that arranges four lamps, which are arranged and formed into a single lamp, as a composite signal lamp, assembled back-to-back in a square tube shape, forms a single tetrahedral signal lamp device, and performs signal operations at a crossroad intersection in one place ( There are proposals such as Patent Document 4).

  Compared with the three-color individual lamp device that illuminates each color by filling up the entire surface of the lamp with exclusive LEDs without including other types of colors, these conventional devices have a mixture of three colors of LEDs and a single lamp in a mixed color state. Therefore, the number of LEDs of one color is reduced to 1/3 in the same frame, and the illuminance density is reduced to 1/3. Even if a condensing lens is used in combination, a decrease in display definition is inevitable, and the above-described drawbacks that occur as long as an LED-arranged lamp is assembled in the above-described tetrahedral signal lamp device will not change.

  In addition, even if three-color display can be performed by irradiating a blue LED with a wavelength conversion plate, there is a problem in obtaining high brightness and high sharpness when a single color obtained by conversion falls within a narrow band. is there.

  Further, in the multi-lamp type signal lamp apparatus which is also in the normal implementation state, the signal operation condition at the signal installation position is set for each single signal lamp, and the setting of the blinking timer is determined uniformly. And until the next signal operation setting opportunity, not only the signal lights do not automatically respond to changes in traffic volume and the number of crossing pedestrians, but also settings that are linked to nearby signal lights are not necessarily made. The display time of different signals and the signal switching timing do not flexibly correspond to the traffic volume.

  However, both the three-color individual signal lamp and the one-color signal lamp to replace it are signal displays for ON / OFF control of the power supply switch to the single-color lamp composed of three-color LEDs, and this signal display system is followed. In order to display a three-color signal on the same display screen of a single-lamp type signal lamp as it is, the size of the LED structure is not small enough to increase the luminance density compared to the size of the signal lamp. was there.

  The problem to be solved is that when the three color signal lights are individually displayed on the same display surface, when the signal illumination for one color is performed, the signal illumination for the other two colors is turned off. A dark portion is generated in the signal light arrangement area for two colors in the frame, and as a result, the illuminance and luminance of the illuminated light for one color are reduced.

  A further problem to be solved is that the blinking operation of the signal light is performed independently for each single signal and does not match the operation conditions of signal lights installed in other nearby locations. Unless the operator manually changes the signal operation condition, it is not consistent with the signal operation according to the traffic change of the car or the person or the blinking operation of the front and rear signal lights.

  The signal display method of the traffic signal lamp according to the present invention converts the display signal command to the signal lamp into digital information, performs the signal control operation by software processing, and displays the three-color main signal image and the auxiliary signal image on the signal lamp screen. This is the main feature.

  In the method of the present invention, the data for the next signal display is stored in the output buffer immediately before the signal display by the operation of the information processing system that manages the plurality of signal command information collected in the information data file, and is displayed collectively in the order of posting The main feature is that it can be transferred to the light.

  Furthermore, the method according to the present invention includes a single signal lamp unit provided with an information processing system for performing signal processing for each single signal lamp or a plurality of signal lamps, and is generated in real time with at least the nearest adjacent signal lamp unit. The next feature is that it is performed in cooperation with the information processing system on the other side of the signal information data communication so that the communication information in the vicinity can be utilized by itself.

  The signal lamp unit used in the method of the present invention includes a signal lamp image display frame that forms a flat display in one lamp frame, a database that stores digitized signal information, a controller that performs image display processing, and a buffer. The most important feature is to form a unit with the other digitizing device elements.

  The signal lamp unit according to the present invention is mainly configured such that a plurality of signal lights directed to the traveling vehicle lane are combined into a single signal synthesis lamp device, and each of these signal lights can be displayed by one information processing system. Features.

  Furthermore, the signal lamp unit of the present invention is a self-generated power source that uses a battery that stores night commercial power, wind power, or a road-mounted piezoelectric element as a power source instead of a commercial power source for a power circuit that supplies power to an operation power source. The following main features are that it can be selected and configured as (8b).

  The signal light unit of the present invention installs a sidewalk monitoring sensor for pedestrians at each pedestrian crossing nearest to the installation of the signal light, and the sensor information is wired or wirelessly as real-time information of the monitoring area via the pedestrian monitoring means. Information is transmitted to the information processing system of the signal lamp unit to enable information operation.

  Here, the flat display (hereinafter referred to as FD) is a liquid crystal display (hereinafter referred to as LCD) suitable for miniaturization, an organic electroluminescence display (hereinafter referred to as organic ELD), and a field emission display (hereinafter referred to as FED). , And a display having a similar function.

  The controller shown here includes an image input means or an image input / output means (not shown), an input / output means for character information, and an operation processing means thereof, thereby displaying information data on a signal indicator lamp, This means screen image processing control. In addition, the self-contained type in the indicator light information processing system means that there is no special command operation from the outside when the hardware part of the signal light and the software part that operates the information processing system shown here are operated integrally. In addition, it means that the signal lights can be operated properly according to traffic signal management.

  The signal display method of the traffic signal lamp of the present invention is not a signal replacement type lighting of color arrangement lighting seen in a conventional single lamp type signal lamp, nor a method of sequentially flashing different color lighting to different kinds of signal lights of three independent frames. It is a one-lamp type signal lamp that can display the image formation of the signal almost at a fixed position using the entire image by digitization information that can use the wear, and by adopting a signal display method utilizing digitization for the signal lamp, There is no unnecessary dark part on the display screen, and there is no possibility of causing a decrease in lighting illuminance or luminance. In addition, there is an advantage that the timing of signal blinking and change of signal form can be easily performed by software processing by remote operation.

  The method of the present invention is provided with a display data buffer for preliminarily storing the digitized signal content sent to the image output circuit, so that different kinds of predetermined single color main signal images can be immediately displayed on the signal lamp display screen. There is an advantage that a matched image can be displayed on a signal lamp display surface instantly even in a composite display using a predetermined auxiliary signal image together or a complicated predetermined mixed signal using two or more colors.

  Furthermore, since the method of the present invention is in a state in which real-time information can be exchanged or communicated with the nearest signal light unit adjacent to the signal light unit, the signal operation of its own signal unit can be flexibly performed to extend or shorten the timing of signal blinking. There is an advantage that the current state of the nearest neighboring land can be publicly displayed using the auxiliary signal image.

  The signal lamp unit of the present invention can use an FD that can be formed to a thickness of several centimeters to several millimeters by a display method that handles digitized information. The FD can reduce the thickness and weight of a signal lamp, and can store and use a plurality of dedicated predetermined signal information as data and store processing operation software that can display the signal lamp screen. Since the controller manages the process control, there is an effect that information storage sufficient for signal lamp signal display, accurate display processing, and quick signal readout can be smoothly performed.

  The signal lamp unit according to the present invention is a conventional signal lamp in which two FDs are back-to-back arranged at the nearest place on one traffic road when the two FDs are integrated back to back to form one signal lamp unit. The traffic light can be controlled with one signal light unit.

  Furthermore, the signal light unit of the present invention can be self-powered from a battery or a self-generated power source so that the signal light unit can be self-contained autonomously even if commercial power from the central power distribution system becomes unusable due to a disaster. This has the effect of suppressing the generation of factors that cause traffic disruption while maintaining the ability to continue the display operation.

  In addition, the signal light unit of the present invention provides a monitoring area including the nearest pedestrian crossing, detects the degree of pedestrians in the area, and stores signal lamp operation processing and warning display to pedestrians as standard information. However, there is an effect that it can be useful for publicity display using images and sounds.

  If the conventional signal lamp is a single-lamp type, the illuminance and brightness of the signal generated when the signal is turned on will be reduced, and the three-color frame type will not cause these inconveniences and inconveniences, such as manually performing the blinking timing for each signal lamp alone The purpose of this is to digitize the signal command and enable individual operations by software operation, so that low power consumption type FD can be used for signal lights, and various signal display and signal light units can be linked to each other. A single-lamp type signal lamp unit that uses a lightweight and multi-function FD has been realized.
