JP2001328483A - Self-advancing marker vehicle using crawler type driving wheel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the problem of failing to secure an appropriate display place in some cases since a conventional marker vehicle can pass only a road and the display device is limited to the road or a shoulder, the problem of large power consumption and the incapability of displaying for a long time besides being hard to see in direct sunlight because of a light emission diode(LED) type display element, and further the limitation of the conventional type to a road display due to restrictions on the display place. SOLUTION: A carrier with crawler type driving wheels is used as this self- advancing marker vehicle in order to freely pass a narrow place, the wasteland and the inclined ground and to be easily installed in a conspicuous place even if a road is damaged at the occurrence of a disaster, and automatic driving and automatic rise and ascent of a display are realized by wireless remote operation, using a magnetic reversal type display that can display for a long time with little power consumption in the event of the disaster or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign car which moves to a destination outdoors such as a road and displays target information.

[0002]

2. Description of the Related Art A conventional self-propelled sign car is a modification of a normal car, which moves on a road, stops on a road or a shoulder, and informs a passing car of accident information or construction information. Was. Light emitting diodes (LEDs) are mostly used as display elements.

[0003]

Since the conventional type is based on an ordinary car, it can only pass on the road. Therefore, the display location is limited to the road or the shoulder, so that an appropriate display location may not be secured. Was. In addition, because of the light emitting diode (LED) type display element, there is a problem that power consumption is so large that display cannot be performed for a long time, and that it is difficult to see when exposed to direct sunlight. Further, the conventional type is limited to the road display due to the restriction of the display location.

[0004]

In order to solve these problems, according to the present invention, the vehicle can be freely installed in a narrow place, a wasteland, a sloping land, or the like, and can be easily installed in a place which is easy to see even if a road is damaged in the event of a disaster. In order to achieve this, a carrier having crawler-type driving wheels is used, and automatic operation and automatic raising and raising of the display are realized by wireless remote control. In addition, a magnetic reversing type display which consumes less power and can display for a long time even in a disaster is used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below. FIGS. 1, 2 and 3 are external views of a sign wheel having a crawler drive wheel according to the present invention. FIGS. 1 and 2 show a running state, in which the display unit is hidden in a cover. FIG.
(A) has shown the state where the display part was standing up. FIG.
(B) shows a state in which the display unit is raised. The crawler drive wheel has a structure similar to a caterpillar, as shown in FIG. 1, and can freely pass through rough terrain, slopes, and the like. Also, since the crawler is made of rubber, it can travel without damaging the pavement.

FIG. 4 shows an example of the configuration of a sign car according to the present invention and a remote controller for remotely controlling the sign car. By operating the buttons on the remote control, the contents are caught by the antenna of the beacon as a modulated radio wave, and the demodulated command information is used to control the driving mechanism and control and display the upright and lifting mechanisms of the display. Content control is performed. Since the distance between the beacon and the remote controller for remotely controlling the beacon is relatively short, the radio wave used can be a weak radio wave that does not require permission. Further, the display information of the display device can be provided through wireless communication of a mobile phone. In this case, it is possible to input information from a remote PC through an Internet browser. In the display unit of the sign car, the information of the compact HTML, which is the Internet browser grammar of the mobile phone sent thereto, is decoded and displayed.

FIGS. 5 (a), 5 (b) and 5 (c)
Shows an example of a mechanism for erecting the display unit. Here, the crank mechanism is driven using hydraulic pressure.

FIGS. 6A and 6B show an example of a mechanism for raising and lowering the display unit. The display can be moved up and down by winding or loosening the wire with an electric motor. For example, a microswitch can be used to detect the positions that determine the upper and lower limits.

FIG. 6 (b) shows an example of a display surface capable of displaying a total of 81 characters, that is, 9 characters vertically and 9 characters horizontally. FIG. 7 shows an example in which one character is represented by 16 × 16 pixels. Each pixel uses the magnetic reversal element shown in FIGS. 8A and 8B. FIG. 8A is a diagram in which the yellow fluorescent reflection surface of the display disk faces upward.
(B) is a diagram in which the black surface of the display disk faces upward. By inverting the two-color discs, variable display becomes possible. FIG. 9 illustrates the principle of this inversion. As shown in FIG. 9, a permanent magnet magnetized to the N pole and the S pole is attached to the disk, and the display surface is held by being attracted by the magnetic field of the cylindrical magnets on the left and right sides of the disk. To reverse the display surface, a pulse current is applied to the coil wound around the cylindrical magnet in a direction that changes the magnetization direction of the cylindrical magnet. Since a cylindrical magnet works as a permanent magnet, no electric power is required to maintain the orientation of the disk, and the magnetization reversal is performed with an extremely short pulse current of 1 millisecond or less. , Very few. As described above, since the magnetic reversal type reflects external light for display, illumination at night becomes a problem, but at night, the surroundings are dark and the disk has fluorescent properties. Requires less lighting.

[0010]

As described above, since the traffic sign according to the present invention has the crawler type driving wheels, it can be used in a narrow place.
It can pass through rough terrain and sloping lands, and can easily reach roads even if the road is damaged in the event of a disaster. Since there are few restrictions on the display location in this way, it can be used not only as a road-related display but also as a multipurpose display. In addition, safety can be increased by using an autopilot. Furthermore, since a magnetic reversing display is used, power consumption is low and a long time can be displayed even in a disaster or the like.
