Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guidance display device used for security signs installed on roads and the like.

When carrying out construction work on the road, it is obligatory to install security signs such as arrow boards that clearly indicate the construction site and guide passing vehicles and pedestrians in the left and right directions. In particular, during nighttime construction work on motorways, since vehicles travel at high speeds, there is a need for quick and accurate warnings to drivers far away.

As such a security sign, an arrow board that is installed on the road and indicates the direction of travel by means of a reflective material or light is conventionally used (see Patent Document 1).

A guidance display device 10 according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a trihedral view for explaining the guidance display device 10 of the present embodiment.

The guidance display device 10 of the present embodiment is installed at a road construction site or the like, and displays a security sign (for example, an arrow board) for guiding traveling vehicles and pedestrians in the left and right directions.

The guidance display device 10 includes a frame 100 , a first rod 110 , a second rod 120 , an outrigger 130 , a guidance display section 150 and a control box 160 .

The frame 100 is a rectangular frame that fixes the guidance display section 150 and other parts. The frame 100 of this embodiment has a rectangular shape, and is installed so that its longitudinal direction coincides with the horizontal direction and its lateral direction coincides with the height direction. A guide display unit 150 , which will be described later, is attached to the frame 100 so as to be visible from the front side (front side) of the frame 100 . A control box 160 for controlling light emission of the guide display unit 150 is attached to the back side (rear side) of the frame 100 .

The first rod 110 is a rod-shaped component that fixes the guidance display device 10 to the top of the road cone 20 installed at the construction site, as will be described later.

The second rod 120 is a rod-shaped part that fixes the guidance display device 10 to the top of the road cone 20 different from the first rod 110 . The outrigger 130 is an extension member that separates the second rod 120 from the frame 100 and the first rod 110, and has a rectangular frame shape. The first rod 110 and the second rod 120 are bar-shaped members parallel to the height direction of the frame 100 , and both ends are configured to be able to be erected and fixed to the top of the load cone 20 .

One end of the outrigger 130 is connected to the frame 100 via a hinge 130a, and the second rod 120 is fixed to the other end. The outriggers 130 are stored close to the frame 100 when stored, and when used, the second rods 120 are moved toward the first rods 110 by swinging at an arbitrary angle in a direction away from the frame 100 with the hinges 130a as fulcrums. to a position spaced apart from Note that FIG. 1 shows an example of swinging about 90 degrees as an arbitrary angle, but the angle may be adjusted as appropriate. Note that the outriggers 130 also function as legs that support the guidance display device 10 from the back side of the guidance display device 10 when the guidance display device 10 is directly placed on the road. That is, when the guidance display device 10 of the present embodiment is directly placed on the road, the lower end of the frame 100 is in contact with the road, and the second rod fixed to the end of the outrigger 130 at a distance from the frame 100 Since the lower end of 120 is in contact with the road, the guidance display device 10 is prevented from overturning.

The guidance display portion 150 includes an arrow-shaped portion 151 and functions as a guidance display plate that indicates a direction to be guided to a traveling vehicle or the like. The arrow-shaped portion 151 is composed of a plurality of LED modules 151a-151i (see FIG. 3). By turning on or off any one of these LED modules 151a to 151i, the guidance display unit 150 can display an arrow shape that is highly visible even at night. Further, the guide display unit 150 is attached to the frame 100 so that the horizontal direction of the arrow-shaped portion 151 and the longitudinal direction of the frame 100 match, and the arrow-shaped portion 151 can be visually recognized from the front side of the frame 100. be done.

Between the frame 100 and the guidance display portion 150, a ventilation hole 152, which is a gap formed between the front surface and the back surface, may be formed so that the wind can pass through. The ventilation hole 152 functions as a vent hole through which air passes, and prevents the guidance display device 10 from overturning due to the pressure of the wind.

The control box 160 is connected to the LED modules 151a to 151i of the arrow-shaped portion 151, and functions as a controller that controls the light emission of each LED module 151a to 151i to control the light emission state of the guidance display portion 150. Also, the control box 160 transmits and receives data to and from other guidance display devices 10 by wireless communication.

Near the four corners of the frame 100, legs 180 projecting from the back side may be provided. The leg portion 180 allows the guide display device 10 to stand on the ground and be stored. 150, the control box 160, etc. have a role to keep a distance so that they do not come into contact with each other.

FIG. 2 is an explanatory diagram showing a state in which the guidance display device 10 is erected and fixed to the road cone 20. As shown in FIG.

The guidance display device 10 has a first rod 110 and a second rod 120 . The second rod 120 is fixed at a position separated from the first rod 110 by the outriggers 130 . These first rod 110 and second rod 120 are fixed to different load cones 20 (first load cone 20a, second load cone 20b).

At the end of the first rod 110, there are two projections 111 that function to prevent rotation and removal of the through-hole (hole) 21 formed at the top of the load cone 20 (first load cone 20a). , 112 and a stopper 113 that abuts against the top of the road cone 20 to position the guidance display device 10 in the height direction.

The two protrusions 111 and 112 are provided at different angles (for example, 90 degrees apart) when the first rod 110 is observed from the longitudinal direction (axial direction).

A through hole 21 into which the first rod 110 or the second rod 120 is inserted is formed at the top of the load cone 20 . The through-hole 21 is formed with a key groove 211 having a portion of the circumference enlarged outward so that the protrusions 111 and 112 can be inserted therethrough.

When inserting the first rod 110 into the through-hole 21 of the first load cone 20a, the protrusion 111 is first inserted into the keyway 211, and then the first load cone 20a is moved 90 degrees from the first rod 110. rotate it. Further, the first rod 110 is inserted into the through hole 21 and the protrusion 112 is inserted into the key groove 211 . At this time, the stopper 113 contacts the top of the first load cone 20a, and the first rod 110 is fixed to the first load cone 20a.

In this state, the protrusion 111 that has passed through the key groove 211 first collides with the stepped portion that is the lower end of the through-hole 21 and is prevented from coming off, and the protrusion 112 that engages with the key groove 211 is prevented from coming off. One load cone 20a is prevented from rotating.

As a result, the first rod 110 is erected and fixed to the upper portion of the first load cone 20a. Similarly to the first rod 110, the second rod 120 is erected and fixed to another load cone 20 (second load cone 20b).

The end of the second rod 120 is provided with two protrusions 121 and 122 and a stopper 123 as with the first rod 110 . The second rod 120 is attached to the guidance display device 10 via an outrigger 130 , and is fixed at a position separated from the first rod 110 by deploying the outrigger 130 .

In this state, the second rod 120 is inserted into the through-hole 21 of the second load cone 20b. At this time, after first inserting the protrusion 121 into the key groove 211, the second load cone 20b is rotated by 90 degrees with respect to the second rod 120. As shown in FIG. Further, the second rod 120 is inserted into the through hole 21 and the protrusion 122 is inserted into the key groove 211 . As a result, the stopper 123 comes into contact with the top of the second load cone 20b, and the second rod 120 is fixed to the second load cone 20b.

In the second rod 120, similarly to the first rod 110, the protrusion 121 that has passed through the key groove 211 first hits the stepped portion of the through hole 21 and is prevented from coming off. An engaging projection 122 is detented against the second load cone 20b.

As a result, the guidance display device 10 is erected and fixed by the two load cones 20 (the first load cone 20a and the second load cone 20b) by the first rod 110 and the second rod 120, and is spaced apart. Since the guidance display device 10 is supported by the two installed road cones 20, the guidance display device 10 is prevented from overturning due to wind or vibration.

In particular, since the guidance display device 10 has a flat plate shape, it is susceptible to force in the plate thickness direction due to the influence of wind such as running wind, even though the wind vent holes (ventilation holes 152) are present. However, when the guidance display device 10 of the present embodiment receives the wind from the front side, the second road cone 20b serves as a support, and the tipping over to the back side is prevented. In addition, when the wind is received from the back side, the weight of the second load cone 20b prevents overturning to the front side.

Both the first rod 110 and the second rod 120 have protrusions and stoppers on both end sides. Therefore, the vertical direction (height direction) of the guidance display device 10 can be changed depending on which end of the first rod 110 or the second rod 120 is erected and fixed to the load cone 20 . Therefore, the vertical direction in which the guidance display device 10 is erected and fixed to the road cone 20 can be appropriately selected. The direction of the arrow can be changed according to the vertical direction at the time of installation.

The guidance display device 10 configured as described above is fixed to the upper part of the road cone 20 generally used at the construction site, so that it is fixed at a higher position than if it is installed directly on the road, and is visually recognized. improve sexuality. Furthermore, by being supported by the two load cones 20 that are spaced apart from each other, the guidance display device 10 is prevented from overturning due to wind or vibration without preparing a dedicated stand or the like. In addition, conventional outriggers are provided on the back of conventional guidance display devices that are placed directly on the road as legs to prevent overturning. By replacing the outrigger 130 with a second rod 120 (or attaching the second rod 120 to the end of a conventional outrigger) and attaching the first rod 110 to the back of a conventional guidance display, A conventional guidance display device can also be changed to have a configuration equivalent to that of the guidance display device 10 of the present embodiment.

Next, the light emitting state of the guidance display unit 150 of the guidance display device 10 will be described.

3A and 3B are explanatory diagrams of the guiding display unit 150, and FIGS. 4A and 4B are explanatory diagrams of the light emitting state of the guiding display unit 150 controlled by the control box 160. FIG.

The arrow-shaped portion 151 provided in the guidance display portion 150 is composed of a plurality of LED modules 151a to 151i. Each of the LED modules 151a to 151i is a substantially rectangular case, in which a plurality of LED elements 155, which are light emitting elements, are fixed.

In addition, 12 LED elements 155 are attached to the LED module 151a of this embodiment, and 6 LED elements 155 are attached to the LED modules 151b and 151c.

These LED elements 155 are configured to emit blue light that is highly visible from a distance, but may be of other colors (red, orange, green, white, etc.). The LED elements 155 are fixed by filling resin around them while attached to the LED modules 151a to 151i.

With such a configuration, by simultaneously lighting the LED modules 151a, 151b, and 151c in the guidance display section 150, the left arrow among the arrows formed by the guidance display section 150 can be lighted. Also, by simultaneously lighting the LED modules 151a, 151d, 151g, 151h, and 151i, the guidance display section 150 as a whole lights up in an arrow shape.

The control box 160 controls lighting of the LED elements 155 of the LED modules 151a to 151i to control the light emitting state of the guidance display section 150. FIG.

As an example, as shown in FIG. 4A, by simultaneously lighting the LED modules 151a, 151d, 151g, 151h, and 151i, it is possible to create a light emitting state in which one arrow is always lit (pattern 1). In addition, by repeatedly turning on and off the lighted arrows at predetermined intervals, it is possible to create a light emitting state in which one arrow blinks (pattern 2).

Also, the LED modules 151a, 151b, and 151c are turned on at the same time and turned off after a predetermined time has passed, the LED modules 151a, 151d, 151e and 151f are turned on at the same time, and after a predetermined time has passed, they are turned off, and the LED module 151a is turned off. , 151d, 151g, 151h, and 151h are illuminated at the same time, the guide display unit 150 can be in a light emitting state in which the arrow shape gradually lengthens from left to right (pattern 3).

In addition, the control box 160 controls the light emission of each of the LED modules 151a to 151i so that the arrow-shaped portion 151 of the guidance display portion 150 can have various light-emitting states (arrow shape, blinking, light-emitting color) other than those illustrated. change, etc.). Furthermore, as will be described later, it is possible to synchronize and control the light emitting state among a plurality of guidance display devices 10 .

More specifically, the light emitting states of the respective LED modules 151a to 151i may be synchronized in timing among the different guidance display devices 10 to emit light.

For example, as shown in FIG. 4B, when three different guidance display devices 10 (guidance display device 10-1, guidance display device 10-2, guidance display device 10-3) are installed, in each guidance display device 10 , pattern 3 can be displayed at the same timing. Specifically, after inverting the short arrow on the left side of each guide display device 10, the arrow is displayed to the center, and finally the long arrow is displayed from the right end to the left end. The light emission state can also be controlled so that these three arrows are repeated at the same timing in each guidance display device 10 .

Next, the control performed by control box 160 will be described.

FIG. 5 is a control block diagram of the control box 160. As shown in FIG.

The control box 160 includes a power supply circuit 601, a battery 602, a control unit 603, a wireless unit 604, a power connector 605, a power switch 610, an illuminance sensor 611, a lighting pattern switching switch 612, a lighting speed switching switch 613, and a battery level LED 614. consists of

The power supply circuit 601 converts power (for example, AC 100V) input via a power cable connected to the power connector 605 into predetermined power (for example, DC 12V). The power supply circuit 601 supplies predetermined power to each part of the control box 160 and the guidance display part 150 when the power switch 610 is turned on.

The battery 602 is charged with power supplied from the power supply circuit 601, and supplies power to each part of the control box 160 when the power supply from the power connector 605 is stopped. The charge capacity (remaining charge) of the battery 602 may be displayed by colors, numerical values, bar graphs, or the like using the remaining battery level LED 614 . The remaining battery level LED 614 may be lit when the control box 160 is activated, so that it can be confirmed from a distance on the back side that the guidance display device 10 is operating.

The control unit 603 acquires the states of the power switch 610, the illuminance sensor 611, the lighting pattern switching switch 612, and the lighting speed switching switch 613, and based on these states, determines the power supply to the LED modules 151a to 151i of the guidance display unit 150. By controlling the supply, the luminous state of the guidance display unit 150 is controlled. Also, the control unit 603 controls the wireless unit 604 to communicate with other guidance display devices 10 and transmit/receive data regarding the light emitting state to/from the other guidance display devices 10 .

Wireless unit 604 communicates with wireless units 604 of other guidance display devices 10 using wireless communication. For wireless communication, for example, ultra-low power wireless, wireless LAN, infrared communication, or the like can be used.

The lighting pattern changeover switch 612 and the lighting speed changeover switch 613 are configured by, for example, push buttons or slide switches, and instructions from the user are input. The control unit 603 determines the user's instruction from the states of these switches, and causes the guidance display section 150 to emit light based on this instruction. As will be described later, these lighting patterns and lighting speeds may be set based on data transmitted from another guidance display device 10 by wireless communication.

For example, the lighting pattern switching switch 612 is configured as a three-step slide switch, and the positions of the three steps can correspond to patterns 1, 2, and 3 shown in FIG. 3, respectively. Also, the lighting speed changeover switch 613 is configured as a three-step slide switch, and the three-step positions can correspond to the three-step flashing speeds (slow, normal, and fast). In addition, the illuminance sensor 611 detects the brightness of the ambient light of the guidance display device 10, and the control unit 603 can adjust the brightness (luminance) of the LED modules 151a to 151i according to the brightness of the ambient light. .

As an example, when the setting of the lighting pattern changeover switch 612 is "pattern 2" and the setting of the lighting speed changeover switch 613 is "3" (fast), the control unit 603 sets the guidance display section 150 to "pattern 2". (blinking of the arrow of the entire light emitting part) is controlled to the blinking light emitting state of "setting 3" (fast).

Next, control of the guidance display device 10 using wireless communication will be described.

FIG. 6 shows an example in which the guidance display device 10 of the present embodiment is applied to a construction site of a motorway. FIG. 6 shows an example in which the guidance display device 10 is fixed on the road cone 20 and a plurality of the guidance display devices 10 are installed at the construction site.

In FIG. 6, a motorway 1000 has lanes 1100 and 1200 running in the same direction, and a work area 2000 for road construction is provided in the lane 1100 adjacent to a side strip 1300 side. A lane boundary line 1110 is drawn between the lane 1100 and the lane 1200 , and a lane boundary line 1310 is drawn between the lane 1100 and the side strip 1300 . A median strip 1400 is in contact with the lane 1200 . The lanes 1100 and 1200 are defined in the direction in which the vehicle travels from the lower side to the upper side in FIG.

A work area 2000 is an area surrounded by a plurality of load cones 20 arranged at regular intervals and the work vehicle 300, which is indicated by hatching in FIG.

On the upstream side of the work area 2000, along with the load cones 20, three guide display devices 10 are provided at predetermined intervals (every three load cones 20).

At the construction site configured in this way, the problem is how to light the three guidance display devices 10 installed separately. If these three guidance display devices 10 are set to the same light emitting state and each of them is operated to operate the power switch 610 to start emitting light, these three guidance displays may differ depending on the timing of the operation and the individual difference of the control unit 603. The light emission state of the device 10 will be completely different.

Therefore, the guiding display device 10 of the present embodiment is configured so that the light emitting states can be synchronized by performing wireless communication with each other through the wireless unit 604, as described below.

In order to synchronize the plurality of guidance display devices 10 with each other, among the control units 603 of the plurality of guidance display devices 10, only one control unit 603 serving as a master device and one or more control units 603 serving as slave devices are determined. do. As a result, the control unit 603, which has become the parent device, sends a command to the control unit 603, which has become the child device, via wireless communication, thereby synchronizing the light emitting state of the guidance display device 10 between the parent device and the child device. can do.

FIG. 7 is a flow chart of control executed by the control unit 603 . Note that this flowchart describes a case where a plurality of guidance display devices 10 are installed at a construction site, as shown in FIG.

The control unit 603 starts this flowchart when it is activated, that is, when the power is turned on.

Note that turning on the power means turning on the power switch 610 while the power cable is connected, turning on the power cable while the power switch 610 is turned on, and In the above state, the case where power supply from the main power supply device (power supply car, power generation device, etc.) connected to the power cable is started is included.

After starting, the control unit 603 determines a predetermined time for determining the timing of transmitting a start signal in step S20 (step S10). As a method of determining the predetermined time, the control unit 603 draws random numbers, for example, and sets the time of the randomly selected random number (for example, 0 to 10 seconds) as the predetermined time. For the random number lottery, for example, a calculation method can be used in which the time of the built-in clock is obtained, and the value obtained by multiplying the number of seconds of the obtained time by 100/60 is rounded to an integer. When the predetermined time is set, the control unit 603 waits for transmission of the start signal until the predetermined time has passed.

The control unit 603 determines whether or not a start signal transmitted from the radio unit 604 of another guidance display device 10 is received during standby for a predetermined time (step S20). When the start signal is received, the process proceeds to step S55. If the start signal is not received, the process waits until a predetermined time elapses (step S30). After a predetermined period of time has elapsed, the control unit 603 transmits a start signal via the radio unit 604 (step S40).

The start signal transmitted by the wireless unit 604 is set as a signal that can be received by any of the wireless units 604 of the other guidance display devices 10 installed at the construction site.

If the control unit 603 does not receive the start signal from the other guidance display devices 10 after a predetermined time has elapsed and transmits the start signal, the control unit 603 is the guidance display device 10 that transmitted the start signal first. It decides itself as the parent device (step S50).

On the other hand, in step S20, if the control unit 603 receives a start signal from another wireless unit 604 before the predetermined time elapses, that is, before it itself transmits the start signal, the control unit 603 starts first. The control unit 603 of the other guidance display device 10 that has transmitted the signal becomes the parent device, and itself is determined as the child device (step S55).

Based on this determination, when a plurality of guidance display devices 10 are installed, the control unit 603 of the guidance display device 10 that first transmitted the start signal after activation is determined as the single parent device. All of the control units 603 of the other guidance display devices 10 are determined as child devices.

Next, the control unit 603 of the guidance display device 10, which has become the parent device, controls the light emitting state of the guidance display section 150 according to the settings of the lighting pattern changeover switch 612 and the lighting speed changeover switch 613 (step S60). At this time, every time the LED modules 151a to 151i of the guidance display unit 150 change in the state of lighting or extinguishing, the control unit 603 transmits a signal to that effect to the child device via the wireless unit 604 (step S70).

The control unit 603 of the guidance display device 10, which has become a child device, waits for transmission of a signal from the parent device. Then, when a signal indicating a change in the state of lighting or extinguishing of the LED modules 151a to 151i of the guidance display unit 150 is received via the wireless unit 604 (step S65), the guidance display unit 150 is controlled based on the received signal. The light-on and light-off states of the LED modules 151a to 151i are controlled (step S75).

By the above control, when a plurality of guidance display devices 10 are installed, by setting the control unit 603 as a parent device and the control unit 603 as a child device using wireless communication, the plurality of guidance display devices 10 light emission states can be changed synchronously.

The control unit 603 is provided with a master unit/slave unit selector switch 615, and the user can switch the master unit/slave unit selector switch 615 to switch the guidance display device 10 to be the master unit and the guidance display device 10 to be the slave unit in advance. Can also be set.

Next, another embodiment of the present invention will be described.

FIG. 8 is an explanatory diagram of the guidance display device 10 of another embodiment of the present embodiment, and is an explanatory diagram showing an example in which the guidance display device 10 is provided with a drive recorder 30. As shown in FIG.

In this embodiment, the frame 100 of the guidance display device 10 is equipped with the drive recorder 30 .

The drive recorder 30 is attached to the end on the right side (tip of the arrow) of the guidance display device 10, facing the upstream side of the construction site (the front side of the guidance display device 10). The drive recorder 30 is an imaging device that records the road conditions as video data seen from the construction site side by imaging the front side, for example, when a vehicle enters the construction site by mistake.

The drive recorder 30 includes a camera 31 and a recording device (not shown). While the drive recorder 30 is operating, video data captured by the camera 31 is recorded in an external memory by the recording device. Further, when the drive recorder 30 detects an impact, it separately records video data for several tens of seconds before and after the time when the impact is detected in the external memory.

Here, as described above, the guide display device 10 can be installed so that the arrow points to the right, or it can be installed so that the arrow points to the left. When the guidance display device 10 is installed so that the arrow points to the left, the drive recorder 30 is upside down compared to the state shown in FIG. put away.

Therefore, the drive recorder 30 of this embodiment includes a gravity sensor for detecting gravity, and is configured to automatically correct the top and bottom of the recorded image according to the direction of gravity. Thereby, the vertical direction of the image captured by the drive recorder 30 is changed according to the vertical direction of the guidance display device 10 .

With such a configuration, when the guidance display device 10 is installed so that the arrow points to the left as shown in FIG. In the case shown in FIG. 8A, control is performed so that recording is performed upside down, so that the vertical direction of the video data captured by the drive recorder 30 can always be recorded in the same direction as the direction of gravity.

The guidance display device 10 of the embodiment of the present invention configured as described above guides a traveling vehicle in the left-right direction.
