Description

Technical Field

[0001] The present invention relates to the technical field of traffic control systems, and particularly to a road traffic safety control system and a control method thereof. Background Art

[0002] Speeding is a very dangerous driving behavior, and its hazards are mainly as follows: interfering with the normal traffic flow, extending the reaction distance, extending the braking distance, decreasing the reaction ability, and aggravating the consequences of accidents. The faster the vehicle speed, the greater the impact force after hitting a person or an object, and the more serious the injuries of the person and the vehicle. Speeding is particularly dangerous, especially on long downhill sections and ramps. At present, the following are mainly the traffic safety measures for speeding on the road: traditional warning lights, LED display screens, and voice warning systems, which are installed at the exits of highway ramps or accident-prone sections.

Detailed implementation manners

[0066] In the description of this embodiment, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0067] Figure 1 It is a road traffic safety control system, as Figure 1 shown, and referring toFigures 2 to 7 It is applied to the road positions that need deceleration, such as on ramps, long downhill sections or a certain position on a straight road, and includes a camera device 700, a data processor 720, a first reminder device 710 and a second reminder device 750.

[0068] The camera device 700 is used to take pictures of the vehicles on the road. The data processor 720 calculates the speed of the vehicle according to the photographed photo information. When the speed of the vehicle is greater than a preset value, the first reminder device 710 projects an overspeed warning reminder onto the windshield of the corresponding vehicle, or projects it at a preset distance in front of the vehicle and moves with the vehicle, so as to continuously remind and warn the driver of the overspeed vehicle to prevent the driver of the overspeed vehicle from missing the reminder warning signal. The reminder projection is in the form of the projection of the word "overspeed" or an overspeed sign or a speed limit sign. The preset value is the maximum safe speed of the current lane. When the vehicle still does not decelerate, the second reminder device 750 projects a red guiding line to guide the vehicle into an automatic deceleration lane. The automatic deceleration lane is an auxiliary ramp of the main lane where the vehicle travels or a normal lane with a deceleration function. An auxiliary deceleration device is arranged on the automatic deceleration lane, and the auxiliary deceleration device is used to absorb the kinetic energy of the vehicle and can safely decelerate the stalled vehicle, so as to ensure the safety of other vehicles on the road and the driver of this vehicle.

[0069] On the road sections that need deceleration, due to the driver's unwillingness to decelerate or other reasons, the vehicle speed is relatively fast. This road traffic safety control system can automatically identify and guide it to forcibly decelerate the overspeed vehicle to ensure road safety. That is, when the vehicle speed is fast, it can automatically guide the vehicle to the automatic deceleration lane, improving the intelligence and safety of the road.

[0070] In some embodiments of the present invention, the road traffic safety control system further includes an acquisition device 740 and a signal transmission device 730. The acquisition device 740 is used to acquire the request information including brake failure sent by the vehicle with brake failure. Specifically, the request information including brake failure sent by the vehicle is that after the vehicle's brakes fail, the vehicle driver actively sends a distress signal of brake failure to the acquisition device 740.

[0071] The signal transmission device 730 sends navigation information including the position of the automatic deceleration lane to the vehicle with brake failure to guide the vehicle with brake failure to the automatic deceleration lane. After the acquisition device 740 acquires the request information of brake failure of a vehicle at a relatively long distance from the automatic deceleration lane, it sends rough navigation information to the vehicle through the signal transmission device 730 so that the vehicle can accurately find the approximate position of the automatic deceleration lane.

[0072] The imaging device 700 is also used to obtain vehicle information of a vehicle with a brake failure within its detection range. The second reminder device 750 projects a red guiding line or a yellow guiding line according to the vehicle information to guide the vehicle into the automatic deceleration lane. After the vehicle with a brake failure is within or moves into the detection range of the imaging device 700, the imaging device 700 can acquire the vehicle. Through the data processor 720 and the second reminder device 750, guiding lines are emitted for precise guidance to ensure that the vehicle with a brake failure can be prepared to enter the automatic deceleration lane. It is possible to perform rough navigation and precise navigation according to the distance between the vehicle with a brake failure and the automatic deceleration lane, that is, continuously remind and guide the vehicle with a brake failure to prevent the vehicle with a brake failure from not entering the automatic deceleration lane due to operational errors or the like after reaching the vicinity of the automatic deceleration lane, resulting in a safety accident.

[0073] In some embodiments of the present invention, the road traffic safety control system further includes a third reminder device. When the vehicle has not entered the detection range of the imaging device, the third reminder device sends an alarm message to the vehicle in front of it according to the current position of the vehicle with a brake failure. The alarm message includes information such as the license plate number and lane of the vehicle with a brake failure, which can be prompted through existing road display screens or through broadcasts in the vehicle. The sent alarm message can remind the surrounding vehicles, so as to remind the surrounding vehicles to avoid, so as to ensure the safety of the surrounding vehicles, especially the safety of the vehicle in front of the vehicle with a brake failure.

[0074] In some embodiments of the present invention, the road traffic safety control system further includes an airbag and a fourth reminder device that sends an instruction to an auxiliary deceleration vehicle or the corresponding staff of the auxiliary deceleration vehicle. The auxiliary deceleration vehicle is used for auxiliary deceleration. The auxiliary deceleration vehicle can be a dedicated vehicle or a vehicle temporarily requisitioned on the road. An airbag is installed at the rear end of the auxiliary deceleration vehicle. At least one auxiliary deceleration vehicle is in a group, and the weights of multiple auxiliary deceleration vehicles in the same group are different, and they decelerate in turn, and auxiliary deceleration vehicles with different weights can block vehicles with brake failures of different masses or speeds.

[0075] When the vehicle with a brake failure is driving on the lane, especially when the distance from the automatic deceleration lane is relatively far, the auxiliary deceleration vehicle can be used for deceleration. The fourth reminder device starts the auxiliary deceleration vehicle through a reminder. The auxiliary deceleration vehicle is located in front of the vehicle with a brake failure and its speed is equal to or greater than the current speed of the vehicle with a brake failure. After the vehicle with a brake failure contacts the airbag, the speed is gradually reduced, so that the speed of the vehicle with a brake failure gradually decreases.

[0076] In a further embodiment of the present invention, the speed of the vehicle with a brake failure can be obtained, and the weight of the auxiliary deceleration vehicle is selected according to the speed of the vehicle with a brake failure and the speed of the auxiliary deceleration vehicle is adjusted.

[0077] In some embodiments of the present invention, the second reminder device 750 is further configured to, after projecting the red guiding line, remind the vehicles that have already been on the guiding line and the vehicles that will pass through the guiding line, so that the corresponding vehicles can change lanes or stop, preventing the vehicles traveling normally from occupying the lane where the guiding line is located, avoiding collisions with the vehicles with brake failures / speeding vehicles, and at the same time ensuring the safety of the vehicles with brake failures / speeding vehicles during the risk avoidance process.

[0078] In some embodiments of the present invention, auxiliary deceleration devices are provided on one side or both sides of the automatic deceleration lane, and the auxiliary deceleration devices are reusable deceleration energy-consuming guardrails. When the vehicle with a brake failure comes into contact with the auxiliary deceleration device, the auxiliary deceleration device can convert the kinetic energy of the vehicle into other forms of energy to achieve the effect of decelerating the vehicle with a brake failure. In particular, the deceleration energy-consuming guardrail is a reusable deceleration energy-consuming guardrail, which can ensure the long-term use of the braking lane and reduce costs.

[0079] In a further embodiment of the present invention, there are multiple deceleration energy-consuming guardrails, which are arranged in two rows and are provided on both sides of the automatic deceleration lane. The arrangement of the multiple deceleration energy-consuming guardrails in two rows can further improve the effect of decelerating the vehicle with a brake failure and can receive the kinetic energy of the vehicle with a brake failure from different directions.

[0080] In a further embodiment of the present invention, along the traveling direction of the vehicle in the automatic deceleration lane, the distance between the two rows of deceleration energy-consuming guardrails gradually becomes smaller, preventing the vehicle from only coming into contact with the deceleration energy-consuming guardrail on one side. When the vehicle with a brake failure comes into contact with the deceleration energy-consuming guardrails on both sides of the automatic deceleration lane at the same time, the resistance that the vehicle with a brake failure encounters when continuing to move forward gradually increases, thereby enabling the vehicle with a brake failure to decelerate quickly.

[0081] In some embodiments of the present invention, the road traffic safety control system further includes a translation device. The translation device is configured to drive the deceleration energy-consuming guardrail to move along the width direction of the automatic deceleration lane, so that the deceleration energy-consuming guardrail moves towards the middle area of the automatic deceleration lane, making the distance between the two rows of deceleration energy-consuming guardrails gradually become smaller. When the deceleration energy-consuming guardrails are not in use, the two rows of deceleration energy-consuming guardrails are at the two edges of the automatic deceleration lane, which is convenient for removing the vehicle with a brake failure that has stopped. At this time, the automatic deceleration lane can be a normally used lane, improving the traffic volume of the road.

[0082] In a further embodiment of the present invention, the deceleration energy-consuming guardrail includes a guardrail, a fixed seat 600, and an energy-absorbing component. The fixed seat 600 is disposed on the automatic deceleration lane, and a cavity structure is defined inside the fixed seat 600. The guardrail is rotatably mounted on the fixed seat 600, and the outer surface of the guardrail is a rubber layer, which is used to increase the buffering of the guardrail and the friction force with the vehicle, so that when the vehicle comes into contact with the guardrail and moves relatively, the guardrail rotates relative to the fixed seat 600, thereby consuming the kinetic energy of the vehicle with a brake failure and decelerating the vehicle. The energy-absorbing component is disposed inside the fixed seat 600 and is used to absorb the kinetic energy generated by the rotation of the guardrail when the guardrail rotates, and convert the kinetic energy into other forms of energy, so as to ensure that the deceleration energy-consuming guardrail can continuously absorb the kinetic energy of the vehicle and enable the deceleration energy-consuming guardrail to be reused.

[0083] When a vehicle with a brake failure enters the automatic deceleration lane, the vehicle comes into frictional contact with the guardrail, and the movement of the vehicle drives multiple guardrails to rotate during the movement process, so that the guardrails consume the kinetic energy of the vehicle and gradually decelerate the vehicle. The setting of the energy-absorbing component can absorb the kinetic energy generated by the rotation of the guardrail, so that the deceleration energy-consuming guardrail can continuously absorb the kinetic energy of the vehicle and enable the deceleration energy-consuming guardrail to be reused.

[0084] In a further embodiment of the present invention, a moving slide rail is fixedly provided on the automatic deceleration lane, and the moving slide rail extends along the width direction of the automatic deceleration lane. The fixed seat is slidably disposed on the moving slide rail. In some other embodiments of the present invention, the fixed seat 600 is fixedly disposed on the automatic deceleration lane.

[0085] In a further embodiment of the present invention, the energy-absorbing component includes a transmission frame 200, a plurality of energy-absorbing gears 300, a plurality of energy-absorbing springs 400, and a one-way part. The transmission frame 200 is rotatably mounted inside the fixed seat and is fixedly connected to the guardrail, so that when the guardrail rotates, the transmission frame 200 is driven to rotate in a first direction. For example, as Figure 6 shown, the first direction is the clockwise direction. The vehicle drives the guardrail to rotate in the clockwise direction. The plurality of energy-absorbing gears 300 are circumferentially distributed along the axis of the guardrail. Specifically, the number of energy-absorbing gears 300 is four. The energy-absorbing gears 300 are rotatably disposed on the transmission frame 200, so that the transmission frame 200 can drive the energy-absorbing gears 300 to revolve around the transmission frame 200.

[0086] One end of each energy absorbing spring 400 is connected to the transmission frame 200, and the other end is connected to the eccentric position of the energy absorbing gear 300, so that when the energy absorbing gear 300 rotates, the length of the energy absorbing spring 400 is driven to change. Each energy absorbing spring 400 corresponds to a telescopic tube 410. The telescopic tube 410 is telescopic, and the energy absorbing spring 400 is installed in the telescopic tube 410, and the telescopic tube 410 can be synchronously telescoped with the energy absorbing spring 400. The telescopic tube 410 protects the energy absorbing spring 400. Specifically, when the connection point between the energy absorbing spring 400 and the energy absorbing gear 300 is at point a, the energy absorbing spring 400 is in the shortest compressed state. When the connection point between the energy absorbing spring 400 and the energy absorbing gear 300 is at point c, the energy absorbing spring 400 is in the longest state. When the connection point between the energy absorbing spring 400 and the energy absorbing gear 300 moves along the cba sequence, the energy absorbing spring 400 is compressed by accumulated force, that is, the vehicle is decelerated. When the connection point between the energy absorbing spring 400 and the energy absorbing gear 300 moves along the adc sequence, the energy absorbing spring 400 is released and becomes longer.

[0087] The one-way portion is arranged in the fixing seat 600 and connected to the energy absorbing gear 300, and is used to make the energy absorbing gear 300 rotate only in the second direction. The first direction is opposite to the second direction, so the second direction is counterclockwise. The one-way portion prevents the energy absorbing gear 300 from rotating in the clockwise direction. When the energy absorbing gear 300 is driven by the transmission frame 200 to revolve in the clockwise direction, the energy absorbing gear 300 is rotated in the counterclockwise direction, driving the connection point between the energy absorbing spring 400 and the energy absorbing gear 300 to move along the CBA sequence, so that the energy absorbing spring 400 is compressed by the accumulated force, and the kinetic energy of the vehicle is converted into the potential energy of the energy absorbing spring 400. When the connection point between the energy absorbing spring 400 and the energy absorbing gear 300 passes point a, the energy absorbing spring is released instantly, and drives the energy absorbing gear 300 to rotate rapidly in the counterclockwise direction, so that the connection point between the energy absorbing spring 400 and the energy absorbing gear 300 rotates to point c, thereby releasing the potential energy of the energy absorbing spring 400. The energy storage and release process makes the deceleration energy-dissipating guardrail reusable.

[0088] In a further embodiment of the present invention, the one-way portion includes a one-way toothed ring, and the energy absorbing gear 300 is a ratchet gear. The one-way toothed ring is a ratchet ring, which is sleeved on the transmission frame 200 and fixed to the fixed seat 600. The one-way toothed ring is ratcheted with the energy absorbing gear 300 so that the energy absorbing gear 300 can only rotate in the second direction. The one-way toothed ring is ratcheted with the energy absorbing gear 300 so that when the energy absorbing gear 300 revolves clockwise, the energy absorbing gear 300 can rotate counterclockwise, thereby driving the energy absorbing spring 400 to contract, and preventing the energy absorbing spring 400 from driving the energy absorbing gear 300 to rotate clockwise during the contraction process.

[0089] In a further embodiment of the present invention, the one-way part includes a one-way gear ring 500 and an energy-absorbing gear ring 510. The one-way gear ring 500 is fixedly connected to the fixed seat 600. The one-way gear ring 500 is a ratchet ring and has a high braking efficiency. The energy-absorbing gear ring 510 is sleeved on the transmission frame 200 and meshes with the energy-absorbing gear 300. The energy-absorbing gear ring 510 is arranged inside the one-way gear ring 500, and the outer peripheral wall of the energy-absorbing gear ring 510 is provided with ratchets so that the one-way gear ring 500 meshes with the ratchets of the energy-absorbing gear ring, and thus the energy-absorbing gear ring 510 can only rotate in the second direction. When the energy-absorbing gear 300 revolves in the clockwise direction, since the energy-absorbing gear ring 510 can only rotate in the counterclockwise direction, the energy-absorbing gear 300 generates a counterclockwise self-rotation. When the energy-absorbing spring 400 is instantaneously released, it drives the energy-absorbing gear 300 to quickly rotate in the counterclockwise direction to drive the energy-absorbing gear ring 510 to rotate in the counterclockwise direction, so that the elastic potential energy of the energy-absorbing spring 400 is converted into the kinetic energy of the rotation of the energy-absorbing gear ring 510.

[0090] In a further embodiment of the present invention, as Figure 6 shown, the one-way part includes a one-way tooth block 520 and an energy-absorbing gear ring 510. The one-way tooth block 520 is fixedly connected to the fixed seat 600. The one-way tooth block 520 is provided with ratchets, and the one-way tooth block 520 is convenient for installation and replacement. The energy-absorbing gear ring 510 is sleeved on the transmission frame 200 and meshes with the energy-absorbing gear 300. The outer peripheral wall of the energy-absorbing gear ring 510 is provided with ratchets so that the one-way tooth block 520 meshes with the ratchets of the energy-absorbing gear ring 510, and thus the energy-absorbing gear ring 510 can only rotate in the second direction. When the energy-absorbing gear 300 revolves in the clockwise direction, since the energy-absorbing gear ring 510 can only rotate in the counterclockwise direction, the energy-absorbing gear 300 generates a counterclockwise self-rotation. When the energy-absorbing spring 400 is instantaneously released, it drives the energy-absorbing gear 300 to quickly rotate in the counterclockwise direction to drive the energy-absorbing gear ring 510 to rotate in the counterclockwise direction, so that the elastic potential energy of the energy-absorbing spring 400 is converted into the kinetic energy of the rotation of the energy-absorbing gear ring 510.

The transmission shaft 110 is vertically arranged inside the guardrail cylinder 100 and is coaxial with the guardrail cylinder 100. The transmission shaft 110 is in a hollow tubular shape. The two ends of the connecting rod 120 are respectively fixedly connected to the guardrail cylinder 100 and the transmission shaft 110, so that the guardrail cylinder 100 and the transmission shaft 110 rotate synchronously. In particular, there may be multiple connecting rods 120. The transmission frame 200 includes a rotating shaft 210 and multiple transmission rods 220. The rotating shaft 210 is vertically arranged inside the fixed seat 600 and is fixedly connected to the transmission shaft 110. The rotating shaft 210 is fixedly inserted inside the transmission shaft 110. The multiple transmission rods are circumferentially and evenly distributed around the rotating shaft. The number of the transmission rods 220 is four. One end of the transmission rod 220 is fixedly connected to the rotating shaft 210, and the transmission rod 220 is arranged in the radial direction of the guardrail cylinder 100. Each energy-absorbing gear 300 is rotatably arranged at the other end of the transmission rod 220.

[0092] A control method for a road traffic safety control system, as Figure 7 shown, for the road traffic safety control system of any one of the embodiments, includes:

[0093] Taking pictures of the vehicles on the road and obtaining the speeds of the vehicles according to the taken videos.

[0094] When the speed of the vehicle is greater than a preset value, projecting the words "overspeed" onto the windshield of the corresponding vehicle, or projecting it at a preset distance in front of the vehicle and following the vehicle. Thus, continuous and eye-catching reminder warnings can be given to the drivers of overspeed vehicles to prevent the drivers of overspeed vehicles from missing the reminder warning signals; the preset value is the maximum safe speed of the current lane.

[0095] In the case that the vehicle still does not decelerate, projecting a guiding line to guide the vehicle into the automatic deceleration lane. An auxiliary deceleration device is arranged on the automatic deceleration lane. The auxiliary deceleration device is used to absorb the kinetic energy of the vehicle and can safely decelerate the stalled vehicle, thereby ensuring the safety of other vehicles on the road and the driver of the vehicle. The vehicle can be automatically guided to the automatic deceleration lane, improving the intelligence and safety of the road.

[0096] In some embodiments of the present invention, the control method of the road traffic safety control system further includes: after obtaining the deceleration request information of the vehicle, sending navigation information including the position of the automatic deceleration lane to the vehicle with a brake failure to guide the vehicle with a brake failure to the automatic deceleration lane. Specifically, the request information including a brake failure sent by the vehicle is that after the vehicle's brake fails, the vehicle driver actively sends a distress signal of brake failure to the acquisition device 740.

[0097] Further, after the imaging device obtains the vehicle information of the vehicle with a brake failure within its detection range, it projects a guiding line to guide the vehicle with a brake failure into the automatic deceleration lane.

[0098] In some embodiments of the present invention, before the imaging device obtains the vehicle information of the vehicle with a brake failure within its detection range, it further includes: sending an alarm message to the vehicle in front of it according to the current position of the vehicle with a brake failure.

[0099] In some embodiments of the present invention, after projecting the guiding line, it further includes: reminding the vehicles that will pass through the guiding line so that the corresponding vehicles can accelerate and drive away, change lanes or stop. This is to prevent the normally moving vehicles from occupying the lane where the guiding line is located, avoid collisions with the vehicle with a brake failure, and at the same time ensure the safety of the vehicle with a brake failure during the risk avoidance process.

[0100] In some embodiments of the present invention, projecting the guiding line includes: obtaining the surrounding ambient brightness; when the ambient brightness is higher than the preset brightness value, projecting a red guiding line. When the ambient brightness is relatively high, the warning effect of the red guiding line is good. For example, during the day, a red guiding line is used and the guiding effect is good. When the ambient brightness is lower than the preset brightness value, projecting a yellow guiding line. When the ambient brightness is relatively low, the warning effect of the yellow guiding line is good. For example, at night, a yellow guiding line is used and the guiding effect is good.

[0101] In some embodiments of the present invention, if the vehicle comes into contact with the auxiliary deceleration device on the automatic deceleration lane, a rescue signal is triggered. An alarm signal, the vehicle position information and the information of the people in the vehicle are sent to the rescue center of the vehicle. The rescue center obtains the vehicle address and the information of the driver of the vehicle, and dispatches a rescue vehicle to improve the timeliness of the rescue.

[0102] In some embodiments of the present invention, after projecting the guiding line, the control method of the road traffic safety control system further includes: sending a speed limit reminder to all vehicles within a preset distance behind the automatic deceleration lane. This is to remind all vehicles within the preset distance behind the automatic deceleration lane to pay attention to safety and avoid the occurrence of secondary accidents.

[0103] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
