Description

{Road sign board working together with nearby road sign boards}

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an interlocking type road sign, and more particularly, to a road sign that periodically blinks in conjunction with an interlocking type road sign.

A number of road signs are installed along the boundary of the road in order to indicate this in a curb road or dangerous area of the road, and it is possible to prevent the vehicle from departing from the road by giving attention to the driver of the vehicle driving at night . These road signs are generally made by attaching a red reflection paper with a gull-like pattern on a rectangular metal plate, fixing it on the upper side of the column, and then placing the concrete.

However, the high-luminance reflection paper attached to the gull road sign has a problem that since the soot generated from the vehicle together with the soil and the dust accumulate on the surface of the reflection paper, the reflection of the light of the vehicle can not be effectively reflected, There is a problem in that it is necessary to periodically replace the reflection paper or to repair it because the surface of the reflection paper is broken off because it is exposed or discolored.

In order to solve such a problem, Japanese Unexamined Patent Publication (Kokai) No. 2001-0035477 discloses a solar cell in which a solar cell 14 is installed outside a guard rail 24 on a curved road as shown in FIG. 4, A road sign 23 has been proposed in which the visibility of the light emitted from the light emitter is improved and the reflector 30 is attached so that the lane can be easily distinguished even when the light is not emitted due to power shortage.

However, such conventional road signs are always turned on at all times, which is insufficient to call attention to the driver. In order to solve this problem, there is a road sign that the light emitting diodes or lamps are flickered at regular intervals, but the road signs are connected to each other by electric wires so that the lamp is powered by the electric wires and the lamp is turned on The installation is inconvenient. In particular, when installing road signs temporarily, such as when installing on roads under construction, installation and demolition are troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a road sign which is simple in installation and light is sequentially blinked. Another object of the present invention is to provide a road sign capable of controlling the blink period according to the degree of curvature of the road.

According to an aspect of the present invention, there is provided an interlocking road signboard comprising: a display unit having a plurality of light emitting means; a selection switch for selecting whether to master or not; a wireless transmitter for wirelessly transmitting signals; A control unit for controlling the display unit to be turned on and off after a predetermined period of time and to transmit a relay signal via the wireless transmission unit when the selection switch is set as a master, The control unit controls the display unit to be turned on for a predetermined period of time and to transmit the relay signal through the wireless transmission unit when the relay signal is received through the wireless reception unit.

In another embodiment of the present invention, the road sign may further include an order number specifying means for specifying an order number. If the selection switch is set to the master, the control unit turns off the display unit for a predetermined period of time after a certain period of time, and transmits the relay signal including information on the first order through the wireless transmission unit. On the other hand, when the selection switch is not set as the master, the control unit lights the display unit for a predetermined period of time and extinguishes the display unit when the information about the order included in the relay signal matches the order specified by the order designation unit And controls to transmit a relay signal including information on the next order through a wireless transmission unit.

The road sign of the present invention may further comprise lighting time setting means for specifying a lighting time. In this case, the control unit lights up for a time designated by the lighting time setting means when the display unit is turned on.

The road sign of the present invention may further comprise lighting period setting means for specifying a lighting period. In this case, when the selection switch is set as the master, the control unit turns off the display unit for a predetermined period of time, and transmits the relay signal through the wireless transmission unit at the intervals set by the lighting period setting unit.

According to the present invention, it is not necessary to connect the road signs to each other by electric wires, and only the first road sign is set as the master, so that the installation is simple and can be installed irrespective of the degree of bending of the road. In addition, there is no limit to the number of road signs that can be installed. In addition, since the blinking cycle and the lighting time can be arbitrarily set, the blinking cycle and the lighting time can be set in accordance with the degree of bending of the road, and the effect of inducing safe driving is high. In addition, it can be used alone, and it is possible to use several road signs linked to each other, so that it can be used to guide the traveling direction in not only a curved road but also a parking lot.

1 is a block diagram illustrating an internal configuration of an interlocking road sign according to an embodiment of the present invention.

The road sign of the present invention includes a display unit 140 having a plurality of light emitting means. As the light emitting means, various light emitting means such as a light emitting diode, an organic light emitting diode, and a bulb may be used. In addition, although the light emitting means is preferably arranged as a gull pattern on the front surface of the road sign as shown in FIG. 3, it may be arranged in various patterns such as arrows, triangles, and letters. On the other hand, when the vehicle is used in a country where the vehicle travels to the left, or when it is intended to indicate the direction to the right, the gull pattern may be constructed in the opposite direction.

In addition to the display unit 140, it is also possible to attach the reflector sheet to the surface of the road signboard, or to attach the reflector sheet to the gull pattern to enhance the visibility. Instead of the reflector sheet, a glittering paint may be applied or a general sheet may be attached.

To this end, the road sign of the present invention is provided with a selection switch 151 for selecting whether to master or not.

The road sign of the present invention also includes a wireless transmission unit 120 for transmitting a signal wirelessly, and a wireless reception unit 130 for wirelessly receiving a signal.

As shown in FIG. 2, the control unit 110 checks whether the selection switch 151 is set to the master (step 210). When the selection switch 151 is set to the master, (Step 220), and controls to transmit a relay signal through the wireless transmission unit 120 (step 230). The steps 220 and 230 are repeated at predetermined time intervals (step 240)

If the selection switch 151 is not set as the master, the control unit 110 checks whether the relay signal is received through the wireless reception unit 130 (step 250) (Step 260), and controls to transmit the relay signal through the wireless transmission unit 120 (step 270).

With this configuration, the display unit is sequentially turned on for a predetermined time from the master road sign to the road signs next to the master sign, and the display unit is turned on as if the light is flowing.

The wireless transmission unit 120 and the wireless reception unit 130 may use various wireless schemes such as an AM (Amplitude Modulation) scheme, a Bluetooth scheme, and a wireless LAN scheme.

The radio wave signal transmitted from the master road sign 100a can reach not only the road sign 100b but also other road signs 100c and 100d. Therefore, since a plurality of road signs may receive a signal and cause malfunction, the road sign may further include an order number specifying means 152 for specifying the order numbers.

With this configuration, the transmitting side can transmit information including the order information when transmitting the radio wave signal, and the receiving side can respond only when receiving the radio wave signal of the order corresponding thereto. That is, when the selection switch 151 is set as the master, the control unit 110 lights up the display unit 140 for a predetermined period of time after a predetermined period of time and turns off the display unit 140 for a predetermined period of time. And transmits the relay signal. On the other hand, when the selection switch 151 is not set as the master, the control unit 110 displays the information on the display unit 140 only when the information on the order included in the relay signal matches the order specified by the order designation unit 152. [ And then transmits the relay signal including the information on the next order through the wireless transmission unit 130. [

3, the road sign 100b has an order of 1, the road sign 100c has an order of 2, the road sign 100d has an order of 3, and a master road sign ( The road sign 100b transmits a radio wave signal including the order information 1, the road sign 100b transmits a radio wave signal including the order information 2, and the road sign 100c transmits a radio wave signal including the order information 3, . Then, after the display unit 140a of the master road sign 100a is turned on and off for a predetermined period of time, the display unit 140a of the road sign 100b is illuminated by the radio signal including the order information 1 transmitted from the master road sign 100a 140b are turned on and off for a predetermined period of time. The display portion 140c of the road sign 100c is turned on and off for a predetermined time by a radio signal including the order information 2 sent out from the road sign 100b. In this manner, the display portion is sequentially turned on as if light flows in the left direction of the drawing.

Meanwhile, according to the embodiment, the road sign may further include lighting time setting means 153 for specifying the lighting time. In this case, the control unit 110 turns off the display unit 140 after lighting it for a time designated by the lighting time setting unit 153 when the display unit 140 is turned on. The lighting time setting means 153 can be constituted by, for example, a DIP switch, and can be configured to select one of a plurality of lighting times such as 0.1 second, 0.2 second, 0.3 second and 0.5 second. Then, the control unit 110 turns on the display unit 140 for a set lighting time, for example, 0.2 seconds.

Further, depending on the embodiment, the lighting cycle can be specified. To this end, the road sign of the present invention may further include lighting period setting means 154. [ In this case, when the selection switch 151 is set to the master, the control unit 110 turns off the display unit for a predetermined period of time, turns off the display unit at the set intervals by the lighting cycle setting unit 154, So as to transmit the relay signal. The lighting period setting means 154 may be constituted by, for example, a DIP switch so as to select one of a plurality of lighting periods such as 0.5 second, 1 second, 1.5 second, and 2 second. Then, the control unit 110 repeats the lighting cycle, for example, the lighting of the display unit 140 and the transmission of the relay signal every 1 second.

Of course, the lighting time setting means 153 and the lighting period setting means 154 may be all provided. With this configuration, it is possible to set the light to move faster or slower depending on the degree of bending of the road. In addition, according to the embodiment, it is possible to configure the lighting time and the lighting period to be set at once. For example, it is configured to select one of repeating every 0.1 second of lighting every 0.3 second, repeating lighting of 0.2 second every 0.6 seconds, repeating lighting of 0.5 second every second, It is possible to do.

Meanwhile, since the lighting time setting means 153, the lighting period setting means 154, and the vehicle sensing portion 160 are components used only in the master road sign, it is also possible to omit it in the slave road sign.

Although not shown in the drawings, the road signboard of the present invention is preferably configured to operate as a battery for simplicity of installation, but is not limited thereto. For example, when a commercial power source can be used as in a case where it is installed indoors, it is also possible to use a commercial power source. It is also possible to use a solar cell to charge the battery from solar heat.
