Description

Road sign board with energy-saving internal lighting}

The present invention makes it possible to attach and detach the sign to the sign by blocking only the part representing the display information, and the display information is emitted through the internal lighting composed of LED light sources inside the block, so that a sufficient lighting effect can be achieved with a small number of LED light sources. It relates to a sign device having an energy-saving internal lighting that enables operation only with power supply by photovoltaic power generation.

In general, traffic safety signs installed on roads display various visual information required for the safe movement of vehicles and pedestrians, such as regulatory signs that restrict the types of vehicles that can be used on the road, people's passage, movement method and direction, etc. Many types of signs are used, such as instruction signs for guiding how to use or directions, and caution signs for informing cautions such as road conditions.

In the past, most of these signs were made using luminous paint or made in the form of attaching a diffuse reflection sheet so that they could be identified by the reflection of the headlights of a driving vehicle.

However, in such a conventional sign, the information to be conveyed through the sign can be perceived by the driver only when the car approaches the position where the sign is erected to the extent that the light from the car's headlights reaches the sign at least at night. It may be difficult for a driver to accurately recognize the sign of a sign and even to recognize the presence of a sign in a changing construction section or a car-only road where high-speed driving is scheduled.

In addition, in the case of a wide road with a wide road width, the range for which the headlights of cars are irradiated is limited, so if a car passing through uses a lane far from the sign installed, the headlights may not reach the sign. In this case, it may be impossible for the driver to recognize the display information displayed on the sign through reflection, no matter how low the driving speed is.

That is, if it is difficult for the driver to recognize the sign, it means that it is difficult to accurately convey information necessary for safe driving to the driver, and furthermore, it can mean that the risk of an accident increases.

In order to improve the problems of the prior art as described above, recently, traffic signs that emit display information through self-illumination have been proposed. Through this, display information can be directly emitted.

However, since self-illuminated traffic signs according to the prior art require a large number of LED elements and consume a lot of power, it is difficult to smoothly supply power only with power generated by solar power generation, and it is difficult to operate only through commercial power supplied from the outside. It is possible, but in order to use such a commercial power source, the introduction of a power line is necessarily required, and installation is limited, but there is a problem that not only construction cost but also operating cost increases.

As a prior art for improving this, Korean Patent Registration No. 10-1672259 discloses a plate-shaped panel member having a plurality of through holes so as to express the contents to be expressed, and inserted into the through hole of the panel member. A sign unit composed of an optical fiber holder member into which the front end of the optical fiber is inserted and fixed, and a light source capable of providing light transmitted through the bundled optical fiber in which the rear end of the optical fiber inserted and fixed into the optical fiber holder member is bundled; a power unit capable of supplying power to the light source of the sign unit; And a control unit for controlling power from the power unit to be transmitted to the light source; an illuminated traffic sign using an optical fiber is proposed.

Illuminated traffic signs using optical fibers have an advantage in that they can be operated with self-produced power using sunlight because they use less power because they can provide sufficient lighting effects with a small light source.

However, since the display information itself is composed of a bundle of optical fibers, micro-voids are formed between the optical fibers, through which foreign substances may be deposited. Since the surface of the sign cannot be kept clean, regular management is required, as well as display using optical fibers. When displaying information, since various colors cannot be expressed, there is a problem in that visibility is deteriorated due to limitations in implementing a unique traffic sign color.

In addition, the control server 80 can monitor information about what kind of display information (a) is indicated in the sign for each location with the result of analysis and analysis.

The control server 80 may include a manager terminal capable of displaying information inquiry and monitoring information of each sign. The manager terminal may be any one of a mobile terminal such as a tablet PC or a smart phone that a manager can carry, or a general PC terminal.

The control server 80 grants access rights to the manager terminal and provides a graphical user interface (GUI) implemented in a web or app environment to view various information processed by the control server 80. make it easy to monitor.

For example, as shown in FIG. 13, the GUI implemented in the control server 80 may include a map displaying the location where each sign is installed on a map, and display information currently displayed on the sign ( a), whether the display panel is normally operating or not, the driving voltage, etc. may be updated and displayed in units of set time.

The control server 80 can input an operation command for a specific signboard by a manager's manipulation, and generates a control signal accordingly and transmits the control signal to the communication module 70 installed in the selected signboard, so that the internal lighting unit 30 of the corresponding signboard ) or the electric sign panel 230 or the setting or operation of the photovoltaic power generation means can be controlled.

In addition, the manager terminal is connected to the control server 80 and can set the second display information of the selected sign, that is, the speed limit of the sign installed in the child protection area.

As an example, FIG. 14 is a speed limit setting screen implemented in a manager terminal. The manager terminal can access the control server 80 through input of unique identification information and can search for a set target sign.

In addition, the manager terminal may set and input a speed limit for each time zone for the searched setting target sign, and according to the input setting information, the control server 80 generates a control signal for applying the set value, and transmits the control signal to the corresponding sign send to

The communication module 70 installed on the corresponding sign receives the control signal transmitted from the control server 80, and the electronic display panel 230 representing the second display information and the electronic display panel 230 displaying the three display information , respectively, so that different speed limits are displayed for each set time period, and when the speedometer measures and displays the driving speed of the vehicle, the speedometer displays a different color in conjunction with the changed speed limit so that an overspeed warning can be guided.

At this time, the sign itself can determine the time by referring to the time output from the GPS module 60.

As such, in the present invention, the speed limit display can be selectively changed from a remote location according to the traffic environment and time of the child protection area, so that the traffic situation in the area can be efficiently operated and the display information on the sign must be replaced. Since there is no maintenance, there is an economic advantage in terms of maintenance.

Through the above description, those skilled in the art will know that various changes and modifications are possible without departing from the technical idea of the present invention. Therefore, the technical scope of the present invention is not limited to the contents described in the detailed description of the specification, but should be defined by the claims.
