Description

Speed-sensitive overspeed prevention system {SPEED REACTION TYPE OVERSPEED PREVENTION SYSTEM}

The present invention relates to a speed sensitive overspeed prevention system, and more particularly, a section in which a crosswalk is formed or a section in which slow motion is to be performed, for example, when a vehicle running in a school zone is determined to be speeded by a speed sensor. The present invention relates to a speed-sensitive overspeed prevention system that drives a drive actuator so that the overspeed prevention protrusion can be raised to induce deceleration of a traveling vehicle.

In general, a crosswalk section is designated on a roadway through which a pedestrian can move to a sidewalk across the road, thereby ensuring the safety of the pedestrian. In other words, a crosswalk is a part of a road marked as a safety sign that allows a pedestrian to cross the road, and unlike pedestrian overpasses or underground roads that require climbing up and down stairs, all pedestrians including pedestrians can cross the road comfortably. It is a transverse facility.

In addition, for the safety of pedestrians, crosswalk markings and crosswalk signs should be installed on the crosswalks, and pedestrian crossings will be provided. Accordingly, when the pedestrian green signal is displayed, the vehicles slow down and wait at the stop line, so that the pedestrian can cross the road safely through the crosswalk.

However, even when a pedestrian green signal is displayed, the safety of pedestrians is often not guaranteed due to the speeding or disorderly driving environment of some vehicles, and pedestrians must enter the crosswalk markings and pass uncomfortably between the stopped vehicles. There is a problem.

Therefore, in the past, a camera for photographing the speeding or a traffic police were conducted to control the speeding area, but recently, the most common method is to install a structure such as a speed bump at a certain point of the road. Overspeed has been suppressed by maintaining the specified speed of.

That is, by using the rainwater contained in the buried enclosure 200 to allow the driver to recognize the overspeed situation in a range that does not interfere with the safe driving, the speed sensor 100 determines the speed vehicle. At the time, the injection nozzle unit 700 by spraying the rainwater to the passenger seat of the vehicle for a short time, the section that is provided with a crosswalk or slow motion, for example, the school zone due to the carelessness of the vehicle driver in the school zone If they do not recognize or do not recognize the pedestrian crossing ahead, the driver can be alerted so that the vehicle driver knows that he is a speeding prevention zone.

In this case, when the rain water sprayed from the injection nozzle unit 700 is sprayed in the driver's seat direction, there may be a risk of another accident by interfering with safe driving, it is preferable to spray in the passenger seat direction of the vehicle, the spray nozzle unit ( In the case of continuously spraying rainwater at 700), it may be desirable to spray at least once for a short time because the sliding surface caused by rainwater on the road surface provides a cause of ice formation in winter.

In addition, the water tank 600 may be provided with a drive pump 620 for driving by the control signal of the control unit 500 to flow the rain water to the injection nozzle unit 700. .

In addition, the above-described injection nozzle unit 700 is described as being installed on the side of the side, but is not limited thereto, and installs a separate support 760 passing through the upper part of the road to correspond to each lane in multiple lanes. It may be made to install a plurality of injection nozzles.

In addition, the injection nozzle unit 700 may be installed on a road on which the vehicle travels, but in this case, damage caused by the driving vehicle and foreign matter present on the road surface may block the ejection hole 721 of the injection nozzle unit 700. Since it will interfere with the injection operation it will be preferable to be installed via the side of the press or the support.

In addition, when the injection nozzle unit 700 is installed in the sidewalk direction, a variety of signs may be installed on the side of the sidewalk to guide the vehicle to slow down, such as speed limit signs or speed limit guide signs within the school zone. In the case where a plurality of injection nozzles are installed at 760, it is to be noted that various signs may be installed on the support 760 and the sidewalk.

Here, looking at an embodiment of the injection nozzle unit 700, the injection nozzle unit 700 is mounted on the flow passage 610 via a connecting extension 711, the thread on the outer peripheral side in the longitudinal direction The main body 710 of the formed cylinder and the nozzle cap 720 is screwed to one side of the main body 710 in the longitudinal direction, but the ejection hole 721 for spraying the fluid introduced into the main body 710 And, installed on the inside of the nozzle cap 720, the outer periphery of the plurality of spiral grooves 731 is formed of a scattering prevention nozzle 730 formed at a predetermined interval.

At this time, the guide pin 740 of a predetermined length is installed on the outer periphery of the scattering prevention nozzle 730, the guide groove 722 is inserted into the guide pin 740 on the inner periphery of the nozzle cap 720 Is installed.

When the rainwater sprayed through the spray nozzle part 700 has a form of scattering, it lowers the driver's attention ventilation and shortens the spraying length, thereby increasing the amount of rainwater falling on the road surface. Therefore, the above problems can be prevented by allowing the spray water sprayed from the spray nozzle part 700 to be sprayed onto the passenger seat of the vehicle in the form of a short stream of water on a certain line rather than being scattered.

In addition, the scattering prevention nozzle 730 is the scattering prevention nozzle 730 by the rain water flowing from the main body 710 due to the guide pin 740 inserted into the guide groove 722 is the nozzle cap It can be prevented from being pushed to the front end of the 720, and the rotation of the scattering prevention nozzle 730 can be suppressed to minimize the scattering during the spray of rain water through the ejection hole 721 of the nozzle cap 720 Will be.

In addition, it is preferable that a vehicle detecting sensor 750 is installed at the front sidewalk side of the injection nozzle unit 700 to detect that the traveling vehicle enters the installation position direction of the injection nozzle unit 700. When the driving vehicle passing through the detection sensor unit 100 is determined to be an overspeed vehicle, when the overspeed vehicle is detected by the vehicle detection sensor 750, the controller 500 drives the driving pump 620 to provide the water. Rainwater filled in the tank 600 is to be sprayed to the passenger seat of the speeding vehicle through the injection nozzle unit 700.

In addition, the water tank 600 is a drain line 640 is provided with a water level sensor 630 for detecting the amount of rain water received and a solenoid valve 650 that is opened and closed by a control signal of the control unit 500. It would be desirable to be installed.

That is, after a certain amount of rainwater filled in the buried enclosure 200 is introduced into the water tank 600 by the submersible pump 230 and filled, the internal water level of the water tank 600 is the water level sensor unit 630. ) Stops the operation of the submersible pump 230 to block the rain water flowing into the water tank (600).

In addition, when excessive rainwater is accommodated in the buried container 200 in a state where rainwater is accommodated in the water tank 600 at the position of the water level sensor 630, the control unit 500 opens the solenoid valve 650. Operate the submersible pump 230 while operating to allow the internal rainwater of the water tank 600 to be discharged so that the rainwater contained in the buried enclosure 200 can be sent to the water tank 600.

On the other hand, the vehicles running on the road are all different in the height of the body, the vehicle having a low body that does not correspond to the height of the protruding height when maintaining the constant height of the protrusion prevention projection 300 without considering this situation In the case of passing through the speed bumps (300) will cause damage to the lower portion of the vehicle body, if the speed of the speed bumps (300) has a higher than the height of the projections to prevent the speed bumps to prevent overspeed Will not be able to perform smoothly.

Accordingly, in the present invention, the vehicle height detection sensor unit 800 is installed on the sidewalk between the injection nozzle unit 700 and the speed detection sensor unit 100 so as to detect the vehicle height of the vehicle.

That is, when the laser emitted from the body sensor sphere at the lowest position among the plurality of body sensor spheres is not received, the controller 500 determines that the traveling vehicle is a vehicle having a low vehicle body, and the speed bumps 300 ) Will protrude to the lowest height.

In addition, when the laser emitted from the vehicle body sensor sphere other than the body sensor sphere of the highest position among the plurality of vehicle body sensor spheres is not received, the controller 500 determines that the vehicle driving is a vehicle having a high vehicle body. Protruding height of the speed prevention protrusion projection 300 to the highest level height to adjust the height of the speed prevention projection projection corresponding to the height of the vehicle body to smoothly perform the function as a projection jaw for speeding prevention do. In this case, when the road is composed of a plurality of roadways, it is preferable that the speed bumps are installed in each lane so that the individual can ascend and descend.

In addition, when a vehicle traveling on each roadway simultaneously passes the position where the vehicle body height sensor unit 800 is installed, the SUV vehicle passes through the first lane on two roadways, When the vehicle passes, the vehicle height of the passenger car in the second lane is determined by the vehicle body detecting unit 820, and whether the vehicle is traveling in the primary road is detected by the height detecting unit 830 and the primary road and the 2nd. Protruding height of the speed preventing protrusion step 300 is installed in the lane it will be desirable to be able to project the same as the height of the vehicle body of the vehicle running in the second lane.

In addition, when the passenger car travels on the first lane and the SUV vehicle travels on the second lane at the same time, the vehicle height detecting sensor unit 800 passes through the installed position at the same time. Since the height is sensed and the height detecting unit 830 detects the height of the SUV vehicle in the second lane, in this case, the speed preventing protrusion projection 300 is projected in response to the height of the passenger vehicle body traveling in the first lane. It would be desirable to.
