Description
- This application claims priority to U.S. provisional patent application No. 60/656,319, which was filed on Feb. 25, 2005 and is incorporated herein by reference in its entirety.
- 1. Field of the Invention
- The invention relates to road markers. More particularly, the invention relates to a road marker having a remotely controllable light display.
- 2. Description of the Related Art
- Road markers are frequently used to delineate the lanes of highways. Road markers, such as shown in U.S. Pat. No. 5,403,115, typically have a plastic shell of trapezoidal cross section which is filled with a potting material. A retroreflective lens is formed by molding cube corners on the inside on angled walls of the shell. The lens reflects light from headlights. However, it is also known such as disclosed in U.S. Pat. No. 5,703,719 to provide retroreflective road markers with LEDs which can be used to improve the visibility of the road marker in daylight. The road marker is provided with a battery and solar cell to recharge the battery as well as a sensor to determine the amount of ambient light present. When the light is above or below a certain amount, the LEDs are displayed to improve the visibility.
- It would be advantageous, however, to provide a road marker which has a display which could be remotely activated to provide warning to a driver of certain conditions such as weather conditions or lane direction reversals which occur during evacuations or heavy traffic periods.
- Advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawing, wherein:
-
FIG. 1 is a perspective view of a road marker according to one embodiment of the invention; -
FIG. 2 is a perspective view of the road marker inFIG. 1 illustrating the internal components of the road marker; and -
FIG. 3 is a perspective view a roadway incorporating the remotely controllable road marker system according to the invention. - According to one aspect of the invention, a road marker includes a shell, a light panel, a power source, a receiver and a controller. The shell has at least one lens. The light panel emits light through the lens. The power source provides electricity for operation of the light panel. The receiver receives control signals from a remote control system. The controller controls the light emitted by the light panel in accordance with the control signals from the remote control system.
- According to another aspect of the invention, a remote controlled road marker system includes a road marker and a remote control arrangement. The road marker has a light panel for emitting light. The road marker has a receiver for receiving control signals. The road marker has a controller for actuating the light panel in response to the control signals transmitted to the receiver. The remote control arrangement includes a central controller and a master controller. The central controller has a transmitter for transmitting the control signals. The master control has both a receiver and a transmitter for relaying the control signals from the central controller to the road marker.
- The invention provides a novel remote controlled road marker system, which includes a remote control arrangement for wirelessly controlling a light-emitting road marker. The road marker according to one embodiment of the invention is generally indicated 10 in
FIGS. 1-3 . Described in greater detail below, theroad marker 10 has a display or light panel that is controlled by the remote control arrangement to display a particular color, such as red, green, blue, or any combination derived from these colors, with the purpose to indicate road conditions. - As shown in
FIG. 1 andFIG. 2 , theroad marker 10 has ashell 20 having at least onelens 22. A rectangularplanar surface 24 is formed along an inner surface of the center of thelens 22. Optionally, thelens 22 may also have cube corners, as known in the art. An edge-lit light panel 30 is mounted to the rectangularplanar surface 24. Thelight panel 30 is rectangular and complementary to theplanar surface 24. A pair of light-emitting diodes (LEDs) are mounted to an end of thelight panel 30. The LEDs emit light onto an edge of thepanel 30. In one embodiment of the invention, the LEDs are mounted between the inner and outer panels so that the light is carried through the length of the panels and evenly displayed on thesurface 24. - A
solar panel 40 is mounted in the top of theshell 20 for recharging abattery 42 which provides a power source for thelight panel 30. The light is capable of displaying a single color or may display one of selected colors such as red, green, blue, or any combination derived from these colors. As shown inFIG. 2 , thelight panel 30 is connected to acontroller 50, which receives power from thebattery 42. Thecontroller 50 is connected to anRF receiver 60, which receives signals from aremote control arrangement 70 to control the operation of thelight panel 30. TheRF receiver 60,controller 50,battery 42 and wiring harness are mounted within theshell 20 in silicone and theshell 20 is potted with fill material, such as polyurethane or other suitable filler materials known by those skilled in the art. - As shown in
FIG. 3 , the remote control arrangement is generally indicated at 70. Theremote control arrangement 70 includes amaster control 72 and acentral controller 80. Thecentral controller 80 controls the overall operation of theremote control arrangement 70. Thecentral controller 80 includes aradio transmitter 82 and receiver. Thecentral controller 80 may be accessed by a user via acentral processing unit 73 or computer. Themaster control 72 includes a radio receiver 74 for receiving signals from thetransmitter 82 of thecentral controller 80. Themaster control 72 also includes a transmitter 76 for transmitting signals to theindividual road markers 10. Thesystem 70 may also include at least onerepeater 90 for relaying the signal from themaster controller 72 orother repeaters 90 todistant road markers 10. By this arrangement, it has been shown that themaster control 72 and/orrepeaters 90 can successfully send signals to an unlimited number ofroad markers 10. Accordingly, depending upon the length of the lane having the remotely controlledroad markers 10, it may be necessary to havenumerous repeaters 90. - The
master control 72 is strategically placed in the trajectory of theroad markers 10. Themaster control 72 includes a plurality of communication port. One communication port is used for information transfer with thecentral controller 80. A second communication port is used for transmitting information to theroad markers 10. A third communication portion is used for transmitting information to therepeaters 90. Additionally, themaster control 72 has digital inputs for interconnection of detection systems such as mist or fog detectors, rain detectors, etc. Themaster control 72 relays signals received from these detectors to thecentral controller 80, which then determines the amount, color and frequency of light to be emitted from theroad markers 10. - The
central controller 80 is housed in a central station that serves to monitor and control the operation of theroad markers 10. Thecentral controller 80 can handle an unlimited number ofroad markers 10 or road marker systems. Thecentral controller 80 can be programmed to cause theindividual road markers 10 to display a light by event or schedule table, manually, or in response to signals from detectors. Thecentral controller 80 can change the color, level of the light, or the lighting of theroad markers 10. Themarkers 10 can be controlled to display as a uniform group continuously or in blinking form. Likewise, themarkers 10 can be controlled to initiate at sequential times such that a synchronous scroll effect or progressive lighting can be provided. - Thus is disclosed an effective intelligent road marker system which can provide necessary safety information to drivers. Colors and sequencing of light can be used to warn the drivers of hazardous conditions including weather conditions such as fog or mist, approach of dangerous conditions such as accidents which require slowing down, or even of the reversal of lane direction such as in evacuations where both lanes of a two-lane highway may be carrying traffic in a single direction.
