It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.
Examples
The intelligent system for height limitation and travel limitation of the municipal bridge of the embodiment is as follows, referring to fig. 1-14: the road traffic monitoring system comprises a detection assembly, a warning assembly and an interception assembly which are sequentially arranged along the advancing direction of a road and controlled by an external controller, and is remarkable in that the detection assembly, the warning assembly and the interception assembly are arranged on a road section on the ground in order to better prevent an ultrahigh vehicle from driving onto a bridge.
(A)
The detection subassembly sets up first base 1 on the road both sides curb including the symmetry, the bracing piece of setting on first base 12, erect horizontal pole 3 between two bracing pieces 2 tops, the display 4 of setting on horizontal pole 3, the symmetry sets up a set of range unit 5 and the symmetry on horizontal pole 3 and sets up a set of first camera 6 on horizontal pole 3, display 4 is in one side that horizontal pole 3 is against road direction of advance, range unit 5's transmission direction is all just facing ground, the direction of advance of road is all being opposed to in the shooting direction of first camera 6.
It should be noted that the type of distance measuring device 5 in the present embodiment employs laser type distance measurement.
It should be noted that in the present embodiment, the supporting rod 2 is a telescopic fixing rod, which can be used for improving the versatility of the detecting assembly (i.e. improving the application range of the detecting assembly), and of course, the supporting rod 2 can also be a rod with a fixed length. In addition, the height of the cross rod 3 from the ground is greater than that of any vehicle running on the road, so that the cross rod 3 can be effectively prevented from being damaged by the collision of the ultrahigh vehicles.
The external controller can then detect the height of each vehicle passing under the crossbar 3 by means of the distance measuring device 5 (wherein the height of the crossbar 3 from the ground is known); the external controller shoots the driving condition of the vehicle through the first camera 6, and can detect and mark the information of each vehicle under the cooperation of the distance measuring device 5 (the information includes the appearance, license plate number and the like of the vehicle); the external controller instructs the display 4 to display the height limit value in front of the road, thereby reminding the driver of knowing the passing conditions of the road in front.
(II)
The warning assembly comprises second bases 7 symmetrically arranged on road shoulders on two sides of a road, electric control telescopic rods 8 arranged on the second bases 7, a cross beam 9 erected between the tops of the two electric control telescopic rods 8, a group of display screens 10 symmetrically arranged on the side wall of one end of the cross beam 9 opposite to the advancing direction of the road, a group of second cameras 11 symmetrically arranged on the cross beam 9 and shooting the direction opposite to the advancing direction of the road, and a group of movable plates 12 symmetrically arranged at the bottom of the cross beam 9.
The content displayed by the display screen 10 includes: the traffic limit height of the road ahead, the information of the ultrahigh vehicle driving past the detection assembly (mainly the appearance picture, license plate number and height value of the ultrahigh vehicle shot by the first camera 6), the road condition of the road ahead and the picture shot by the second camera 11 on the same lane.
The second camera 11 is used for monitoring the real-time situation on the road surface, and meanwhile, the second camera 11 also judges the important monitoring detected component to be the motion state of the super-high vehicle, so that an external controller can timely take corresponding measures (including (1) whether to start the intercepting component, and (2) whether to extend the electric control telescopic rod 8, so that the height of the cross beam 9 is higher than that of the super-high vehicle, and the bottom end of the movable plate 12 is lower than that of the super-high vehicle).
The movable plate 12 is rotatably connected to the rotary hinge seat 17 at the bottom of the cross beam 9, so that the movable plate 12 can be always kept in a plate-surface-downward state, and a driver can timely realize that the vehicle (at an ultrahigh position) collides with the movable plate 12 and stops advancing.
The plate surface of the movable plate 12 is uniformly distributed with ventilation holes to ensure that the structure of the movable plate is the same as that of a grid plate, so that the air resistance of the movable plate 12 (under the action of the rotary hinged support 17 and the self gravity after being impacted by an ultrahigh vehicle) in the rotary process can be effectively reduced; in addition, the swivel hinge base 17 helps the movable plate 12 to rapidly get out of the swing state and enter the stationary state during the swivel process. Meanwhile, the ventilation holes are matched with the rotary hinged support 17, so that the movable plate 12 can be effectively prevented from shaking or inclining due to wind, and a driver can timely and accurately realize that the (super-high) vehicle collides with the movable plate 12.
The top of the beam 9 is also symmetrically provided with a group of solar panels 18 controlled by an external controller, and because the height of the beam 9 from the ground is higher, the sunlight above the beam 9 is more abundant, so that the solar cells can be used for absorbing the sunlight to generate electricity and supplying power to the electricity-using components in the invention, thereby reducing the long-term operation cost of the invention.
(III)
The intercepting components comprise a soft intercepting component and a hard intercepting component which are sequentially arranged along the advancing direction of the road, the soft intercepting component is a group of deceleration strips 13 which are hidden in the road surface and can extend out of the road surface, and the hard intercepting component is a group of vehicle stopping lifting columns 14 which are hidden in the road surface and can extend out of the road surface.
The deceleration strip 13 can actively decelerate the vehicle running on the road in advance, so that the vehicle-stopping lifting column 14 can extend out of the ground more safely; that is, the soft intercepting component and the hard intercepting component are matched to enable the intercepting component to safely and effectively intercept the ultrahigh vehicle (namely, the ultrahigh vehicle and the normal vehicle are effectively prevented from colliding with the vehicle-stopping lifting column 14, and conversely, the design also effectively prolongs the actual service life of the intercepting component).
It is worth noting that the number of the first cameras 6 is equal to the number of the second cameras 11 is equal to the number of the display screens 10 is equal to the number of the movable plates 12 is equal to the number of the distance measuring devices 5 is equal to the number of the soft intercepting components is equal to the number of the hard intercepting components is equal to the number of the lanes of the road, and the width of the display 4 is equal to the width of the road; and each lane on the road is correspondingly provided with a first camera 6, a second camera 11, a display screen 10, a movable plate 12, a distance measuring device 5, a soft intercepting component and a hard intercepting component. This allows the external controller to monitor and control each lane individually, thereby saving the operating cost of the present invention. In addition, if the user feels that the effect of the independent operation of the intercepting components on each lane is not good, the user can input instructions through the external controller, so that the intercepting components on all the lanes are synchronously controlled by the external controller (namely, when ultrahigh vehicles pass through the warning component on one lane, the intercepting components on all the lanes are started).
In the present embodiment, the number of the speed bumps 13 in the same soft intercepting assembly is five, and the number of the car stopping and lifting columns 14 in the same hard intercepting assembly is three.
The car stopping lifting column 14 is detachably fixed in a corresponding lifting groove 28 in the road surface, the top of the car stopping lifting column 14 is flush with the ground when the car stopping lifting column is completely retracted, and the height from the top of the car stopping lifting column 14 to the ground when the car stopping lifting column is completely extended is 1.2 meters, because the car is generally a truck in reality, and the height of the chassis of the truck is generally 0.9 meter.
When the electric push rod 27 is completely contracted, the limiting plate 26 is completely received in the strip-shaped groove 25; when the bottom plate surface of the horizontal plate 22 is in contact fit with the top plate surface of the limit plate 26 and the damping spring 23 is only under the action of the gravity of the speed bump 13, the speed bump 13 just extends out of the ground.
(IV)
The first base 1 and the second base 7 have the same structure; the first base 1 is buried underground in the part below the ground and has seted up a set of anti-skidding groove 15 along the axis direction of first base 1 and according to equidistant linear array's mode, anti-skidding groove 15 is seted up a set of breach groove 16 on first base 1 by the axis that uses first base 1 as the symmetry axis and according to equidistant circumference array's mode and constitutes, like this alright increase the stability and the reliability of first base 1 and second base 7 through breach groove 16 effect, it is worth noting, when actual installation, the ground of first base 1 and second base 7 department need adopt cement or concrete placement to form.
(V)
And a trigger mark line 19 is also sprayed on each lane of the road surface between the detection component and the warning component. Thus, the external controller can monitor whether the ultrahigh vehicle crosses the trigger mark line 19 through the second camera 11, if the ultrahigh vehicle crosses the trigger mark line 19, the external controller immediately instructs the beam 9 to rise (the ultrahigh vehicle can only contact the movable plate 12) (this does not include the beam 9 in the warning assembly at the rear end of the intercepting assembly), and simultaneously instructs the intercepting assembly to enter a standby state, and if the ultrahigh vehicle passes through the warning assembly, the external controller immediately instructs the intercepting assembly to start.
A group of flashing lamps 20 are buried in each lane of the road surface between the detection assembly and the soft intercepting assembly, and the flashing lamps 20 are controlled by an external controller. Wherein the flashing light 20 is used for pre-warning before the interception component is started, so that vehicles on the road can be decelerated in advance in time. Note that the winker lamp 20 is normally in an off state.
And a warning assembly controlled by an external controller is arranged on the road behind the hard interception assembly, and the movable plate 12 is not arranged in the warning assembly. Notably, the display screen 10 on this warning assembly is used to display information beyond the appearance and license plate number of the vehicle. In addition, the second camera 11 on the warning assembly can help the external controller to further monitor the motion state of the ultrahigh vehicle after being intercepted by the intercepting assembly (mainly detect whether the ultrahigh vehicle has the behavior of backing up and withdrawing from the original road), and when the external controller monitors that the ultrahigh vehicle backs up and retracts to the trigger identification line 19 from the original road, the external controller will instruct the intercepting assembly to enter the closed state.
It should be noted that the images captured by the first camera 6 and the second camera 11 are calculated and processed by the machine vision technology in the external controller, so as to more accurately analyze the motion state of the vehicle and the characteristics of the vehicle.
It should be noted that the first camera 6 and the second camera 11 both have a night shooting function, so that the present invention can work around the clock.
The working principle is as follows:
it is worth noting that the road where the previous camera is located in an effective shooting picture of the next camera, and the first camera 6, the second camera 11 and the second camera 11 are sequentially distributed on the same lane.
The external controller monitors vehicles and road conditions running on the road surface in real time through the first camera 6 and the second camera 11.
In the initial state: the display 4 displays the height limit height of the road in front; the display screen 10 displays the height limit of the road in front; the height of the free end of the movable plate 12 from the ground is equal to the height limit height of the front road; the flashing light 20 is off; the interception component is closed.
Firstly, when an ultrahigh vehicle passes through the detection component, the detection component immediately sends the shot ultrahigh vehicle image and the height value thereof to the external controller.
And secondly, immediately instructing the display screen 10 on the corresponding lane to increase and display the shot ultrahigh vehicle image, the license plate number of the ultrahigh vehicle and other contents by the external controller.
And thirdly, the external controller monitors the motion state and the track of the ultrahigh vehicle in real time through the second camera 11, and when the ultrahigh vehicle crosses the trigger identification line 19, the external controller immediately instructs the beam 9 to rise (the ultrahigh vehicle can only contact with the movable plate 12) (which does not include the beam 9 in the warning assembly at the rear end of the intercepting assembly), and simultaneously instructs the intercepting assembly to enter a standby state.
Fourthly, when the ultrahigh vehicle passes through the warning assembly, the external controller immediately instructs the flashing lamp 20 of the corresponding lane to start, and simultaneously sequentially lifts the deceleration strip 13 and the lifting vehicle stopping post of the corresponding lane; meanwhile, the display screen 10 of the corresponding lane on the warning component at the rear end of the intercepting component displays the height limit height of the road in front, the shot picture of the ultrahigh vehicle and the license plate number of the ultrahigh vehicle.
And fifthly, after the original reversing path of the ultrahigh vehicle returns to the triggering indicating line, the external controller instructs the flashing lamp 20 and the intercepting component to be turned off.
And sixthly, when the original road of the ultrahigh vehicle returns to one end of the detection assembly in the vehicle-coming direction, the external controller instructs the warning assembly at the front end of the intercepting assembly to recover the initial state.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
