Description

Technical Field

[0001] The present invention relates to the technical field of intelligent traffic warning devices, and in particular to a traffic guide angle lane setting system based on real-time road conditions. Background Art

[0002] In highway operations, road occupation construction can only be carried out after approval by the traffic management department. Daily maintenance operations are mainly concentrated in the daytime, and special construction operations are concentrated at night. However, due to the high speed and complex road conditions of highway traffic, especially the high traffic flow in medium and large cities, road occupation operations have many traffic operation hazards. At present, behind the cone vehicle in the highway traffic guidance and road occupation operation mode, there is a collision avoidance and buffer vehicle to perform safety protection operations.

[0003] The anti-collision buffer vehicle always drives together with the cone stacking vehicle and maintains a certain safety distance from the cone stacking vehicle, which is kept at about 50 meters; after completing the deployment of facilities with a length of not less than 50m, the anti-collision buffer operation vehicle merges into the operation area from outside the operation area; after being deployed in the buffer zone, the anti-collision buffer operation vehicle is parked in the buffer zone, and is required to turn on the arrow induction sign, turn the wheel to the safe direction of the non-driving side, activate the handbrake, set the vehicle blocker, and no one is allowed to be in the vehicle when parked. The driver can guide traffic in a safe area.

[0004] When removing traffic safety facilities, reverse the vehicles and remove them in sequence. When removing the upstream transition zone, if facilities such as cones affect the passage of the anti-collision vehicle, the maintenance personnel quickly retract the cones inwards away from the driving lane, and the anti-collision buffer vehicle continues to reverse synchronously. During this process, the operators are always 5 cones ahead of the anti-collision vehicle; drive out of the upstream transition zone 50 meters away from the starting point of the operation area, and at the same time, the operators remove the remaining 50m of traffic safety facilities from the side away from the driving lane. Pay special attention to the arrow induction lights of the anti-collision buffer vehicle during this process; when working in the inner lane, if conditions permit, tools such as hooks and ropes can be used to recycle the cones in the central isolation zone.

[0005] However, according to accident statistics from a certain anti-collision vehicle manufacturer, the number of accidents with anti-collision vehicles is more than 600 per year, which is an astonishing number of accidents. From the perspective of highway operators and companies using anti-collision buffer vehicles, each accident will cause varying degrees of personal injury and vehicle property damage, because accidents may even cause production and operation to stop, causing huge losses.

[0006] The root cause of all accidents is essentially because the speed of "any type" of operating vehicles is slow at the beginning of highway traffic guidance operations, averaging between "30km / h and 0km / h", which is a huge difference from the speed of social vehicles. However, the current technologies are: traffic guidance operation technology; intelligent deployment of highway maintenance operation areas; traffic guidance simulation system and full process control; road occupation, accident and mobile operation warning wizard; laser projection signs and signs; spectrum projection signs and signs; remote mobile control cones; luminous warning cones; active warning equipment; deployment ball monitoring; anti-collision buffer car; on-site mobile monitoring; multi-function baton; video and positioning command helmet; automatic stacking recovery and guidance vehicle; new intelligent guidance facility networking; AutoNavi digital construction solution.

[0007] By listing the above technologies, it is not difficult to see that the technologies and applications focusing on highway traffic guidance operations are becoming more and more abundant, but accidents still happen. As a highway operator, the biggest challenge faced by the applicant in construction operation practice is that the speed of the outside vehicles is faster than the operating vehicles, and the risk continues throughout the entire operation cycle.

[0008] The anti-collision buffer vehicle is a highly functional vehicle with sound and light control, energy absorption and cloud reminders. Its main function is to prevent fatal accidents and reduce the degree of injury. However, after the introduction of the anti-collision buffer vehicle, it was objectively regarded as a direct object of collision by social vehicles, which deviated from the original intention of the highway operating unit. In addition, when the anti-collision buffer vehicle is used for safety protection operations, the speed needs to be reduced to 30km / h~0km / h, but there is no closed lane area behind it, which is somewhat inconsistent with the national standard GB57668.4.

The system provided by the present invention mainly includes the following structural components:

[0111] The laser projection chamfering device 4 is used to project an image of a chamfered triangle strip-shaped closed area and / or an optical warning signal to the surrounding area of ​​the motor vehicle.

[0112] Control device for:

[0113] Based on the safety notification information of the work area and in combination with the received work mode instructions, the traffic guide angle delivery device is controlled to deliver the cone barrel while a single working motor vehicle is in motion; during the process of delivering the cone barrel while a single working motor vehicle is in motion, the driving trajectory of the working motor vehicle is controlled;

[0117] The operation mode instructions include: single-vehicle vertical straight line layout instructions, single-vehicle multi-line layout instructions, multi-vehicle vertical straight line layout instructions and multi-vehicle multi-line layout instructions.

[0118] Among them, the detection and evaluation device and the control device can be installed at appropriate locations in the motor vehicle according to actual needs, and therefore are not shown in the figure.

[0119] The basic working process of the system provided by the present invention is as follows: the detection and evaluation device of the working vehicle pre-stores the working position information. After arriving at the working area, the working vehicle obtains the traffic situation information in real time through the detection and evaluation device, analyzes the obtained traffic situation information, obtains the working area safety notification information, and sends it to the working personnel in the vehicle. The working personnel make corresponding judgments based on the working area safety notification information, start the working process through the control device, deploy the traffic guide angle delivery device, and rely on the control device to execute the corresponding working mode instructions, and the system automatically performs the cone barrel delivery operation.

[0120] In the preferred embodiment provided by the present invention, the detection and evaluation device evaluates the driving conditions of the vehicle behind the vehicle through the evaluation detection device, determines the unsafe distance with the rear vehicle, and transmits it to the front-end evaluation feedback device in real time, reminds the driver of the real-time road conditions, issues a warning prompt effect, cooperates with the cone bucket vehicle in front and is associated in real time, and maintains close operation communication and safe distance through the collaborative operation voice device; secondly, through mechanical or voice control of the cone bucket clamp control switch, the fixed position cone bucket releasing device moves slowly with the vehicle and releases it gradually, generating a 20-meter chamfered triangular belt-shaped closed area similar to the upstream transition zone, and the cone bucket 3 releasing device at any position can generate a straight line releasing state, and finally generates a closed area of ​​about 30 meters; thirdly, during and after the delivery operation is completed, the laser projection chamfering device 4 is turned on to project a virtual closed area of ​​about 30 meters behind the anti-collision vehicle, and the special cone buckets are uniformly moved to the safe side and uniformly recovered.

[0121] Accessory parts include various sensors, mechanical parts, electrical materials and circuit accessories;

[0122] During road construction, there are guide areas on both sides of the closed area, which are approximately triangular in shape and can easily guide vehicles to merge. The closed area is demarcated by placing cones at intervals. According to the direction of the line, there are straight lines along the direction of the road, and there are also oblique lines with a certain angle along the direction of the road. Figure 2 The specific execution process of the above-mentioned single-vehicle multi-line layout instruction in the preferred embodiment provided by the present invention is described.

[0123] like Figure 2 As shown in the figure, A1 to A5 are the oblique operation lines, i.e. the parallel guide area, B3 to B1' are the straight (vertical) operation lines, each point is the placement point of the cone barrel, and there are several lengths of straight lines after B1, i.e. the closed main area (omitted in the figure). The applicant found in the operation practice that the conventional layout method is only to arrange them in sequence along the driving direction, but the starting placement point and the end point of the placement are both determined by manual visual judgment. In this process, the vehicle speed needs to be strictly limited, the operation efficiency is low, and due to the slow speed of the operating vehicle, social vehicle rear-end collision accidents are prone to occur. Therefore, predetermining the positions of the oblique starting point and the oblique end point is the key to ensuring the operation efficiency and realizing automated operation. In the preferred embodiment provided by the present invention, the execution process of the oblique layout instruction is as follows:

[0124] S1 calculates the slant distance of the oblique delivery route based on the preset length information and width information of the work area road;

[0125] S2 calculates the starting point and the ending point of the oblique delivery based on the oblique distance of the oblique delivery route;

[0126] S3 calculates and obtains a cone barrel delivery point between the starting point and the ending point of the oblique delivery based on the oblique distance of the oblique delivery route and the starting point and the ending point of the oblique delivery;

[0127] S4 calculates and obtains, based on the execution result of step S3: the vehicle speed during the oblique delivery process, and the delivery interval of the cone barrel delivery points between the starting point and the end point of the oblique delivery;

[0128] S5 calculates the distance of the vertical delivery route based on the preset length information of the work area road and the end point of the oblique delivery;

[0129] S6 calculates the delivery interval of the vertical delivery route based on the distance of the vertical delivery route, combined with the end point of the oblique delivery and the vehicle speed during the oblique delivery process;

[0130] S7 performs the operation of oblique delivery in sequence based on the starting point of the oblique delivery and the execution results of steps S4 and S6 ( Figure 2 A1 to A5) and vertical placement operations ( Figure 2 B3 to B1').

[0131] In the embodiment provided by the present invention, a row of horizontal cone barrels 3 are hung on the work vehicle, and when performing an oblique delivery operation, the cone barrels 3 are delivered in sequence from left to right or in the opposite direction, that is, the oblique delivery operation can be completed on the basis of keeping the vehicle traveling in a straight line. Therefore, the oblique direction should be understood as the line connecting the cone barrels on the road surface is oblique relative to the extension direction of the road, and the vertical direction should be understood as being consistent with the extension direction of the road. In addition, both oblique and vertical delivery operations are not affected by changes in the extension direction of the road. The change of lanes or the tendency of a vehicle on a one-way road is called merging or driving diagonally.

[0132] In actual operation, not only can a single vehicle be operated in the above manner, but also multiple vehicles can be networked and operated in coordination. Figures 3 to 5 As shown, a dual-vehicle network is used as an example, that is, the operating motor vehicle includes a cone barrel delivery vehicle and an anti-collision buffer vehicle, both of which are equipped with this system. According to the arrangement of the cone barrels 3 in the figure, it can be known that the operating area can be understood as a combination of an oblique delivery route and a vertical delivery route. Figures 3 to 5 As shown, the entire area includes the upstream transition zone (oblique route), the midstream buffer zone (oblique route) and the closed working area (multi-directional route), among which the midstream buffer zone and the closed working area are interconnected to form a construction operation area. Figures 3 to 5 It represents the process status of three kinds of operations respectively. Figure 3 The upstream transition zone has been arranged and the midstream buffer zone is beginning to be laid out. Figure 4 The layout of the midstream buffer zone has been completed. Figure 5 The layout for the closed working area has been completed and the entire working area has been set up.

[0133] In an example of a two-vehicle collaborative operation forming a multi-vehicle multi-line layout instruction, the specific process is as follows:

[0134] E1 sets up a cone barrel placement vehicle as the operation command vehicle, and builds an operation formation with the cone barrel placement vehicle in front and the anti-collision buffer vehicle in the back;

[0135] E2 divides the upstream transition area, midstream buffer zone and closed operation area based on the location information of the preset operation area roads;

[0136] E3 (cone placement vehicle) distributes the information of the upstream transition zone to the anti-collision buffer vehicle, so that the anti-collision buffer vehicle performs the cone placement operation in the upstream transition zone by calculating the starting point of the oblique placement, the vehicle speed during the oblique placement, and the placement interval of the cone placement points between the starting point and the end point of the oblique placement based on the information of the upstream transition zone;

[0137] Based on the information of the midstream buffer zone, E4 performs the cone placement operation in the midstream buffer zone by calculating the starting point of the oblique placement, the vehicle speed during the oblique placement, and the placement interval of the cone placement points between the starting point and the end point of the oblique placement;

[0138] E5 calculates the distance of the vertical delivery route and the starting point of the vertical delivery based on the information of the closed operation area; it should be understood that since it is easier to determine the parameters of the vertical route than the oblique route, the calculation of the relevant parameters of the vertical route in the front section of the closed operation area may be slightly different, that is, the information of the delivery end point of the midstream buffer zone is not used, and the starting point of a vertical route is directly calculated using the information of the closed operation area;

[0139] E6 calculates the delivery interval of the vertical delivery route based on the distance of the vertical delivery route and the starting point of the vertical delivery, combined with the vehicle speed during the delivery process in the midstream buffer zone;

[0140] Based on the information of the closed operation area, E7 calculates the starting point of the oblique delivery, the vehicle speed during the oblique delivery, and the delivery interval of the cone barrel delivery points between the starting point and the end point of the oblique delivery;

[0141] E8 executes the cone placement operation in the closed working area based on the execution results of steps E6 and E7.

[0142] It should be understood that the purpose of setting up the command vehicle in step E1 is to make the execution subject of the above process unified as a special vehicle for placing cone barrels. The above step E3 is executed by the command vehicle commanding the anti-collision buffer vehicle, and step E4 is executed by the command vehicle. The execution order of the two steps can be as follows: Figure 3As shown, the anti-collision buffer vehicle is first ordered to build an upstream buffer zone. When the anti-collision buffer vehicle is placed on the 4th or 5th cone barrel, the command vehicle starts to execute step E4. Of course, the two steps can also be executed at the same time (if the road conditions permit). The command vehicle monitors the operation progress of the anti-collision command vehicle through the Internet of Vehicles. Both sequential and simultaneous placement can achieve the layout effect of double / multi-angle operation areas.

[0143] After the closed working area is completed, the working command vehicle orders the anti-collision buffer vehicle and the road construction work vehicle to enter the closed working area divided by cones, and places the road construction work vehicle between the anti-collision buffer vehicle and the special vehicle for placing cones.

[0144] The calculation methods of the above parameters (such as the location information algorithm based on the map, the distance calculation method, etc.) are based on the prior art and will not be repeated here. In addition, in step E3 of the above embodiment, the basis for calculating the vehicle speed during the delivery process includes an analysis based on the road conditions. If the local traffic flow is large, the vehicle speed will be slower. After the upstream transition zone is completed, social vehicles will be forced to merge, thereby constructing a car-free area in front, and the vehicle speed can be increased in subsequent delivery.

[0145] In the preferred embodiment provided by the present invention, Figure 1 As shown, the traffic guide angle delivery device includes:

[0146] The cargo compartment 1 is arranged at the rear of the motor vehicle (i.e., behind the front of the vehicle) and can be used to store accessories, related control equipment, and accommodate additional operating personnel.

[0147] The delivery skeleton 2 is connected to the rear of the cargo compartment 1 and is connected to the cone barrel moving mechanism (the rear of the cargo compartment 1 is open), and is used to deliver the cone barrel onto the road surface. The delivery skeleton 2 includes a frame body 21 of a frame-type structure, and a top structure 22 installed above the frame body 21; the frame body 21 is connected to the rear of the cargo compartment 1, and is open at the bottom, and is used to deliver the cone barrel 3. The enclosed area of ​​the frame body 21 has a horizontal partition structure, which divides the frame body 21 into two layers of space, and the bottom surface of the partition structure (i.e., the lower space) has a first delivery fixture mechanism group. The bottom surface of the top structure 22 has a first transmission chain mechanism (i.e., located in the upper space).

[0148] The first delivery fixture mechanism group includes five first cantilevers 26 that are vertically suspended and installed. The five first cantilevers 26 are arranged in sequence along the width direction of the partition structure, and the five first cantilevers 26 are staggered so that the first cantilevers 26 at both ends are spaced apart from both sides of the frame 21 (the space is used for side delivery of the cone barrel 3). The bottom end of each first cantilever 26 has an electric claw 28 for grabbing, hanging and delivering the cone barrel 3. The staggered arrangement of the five first cantilevers 26 can be as follows: Fig.10As shown, that is, three first cantilevers 26 are relatively at the back, and two first cantilevers 26 are relatively at the front, presenting an overall "dish" shape. Fig.10 Taking the positional relationship of the suspended cone barrels 3 as an example, the position of the first cantilever 26 can be known through the cone barrels 3, so it is not shown in the figure. The staggered arrangement can save space and effectively limit the width of the frame 21, making the overall layout relatively compact. In the embodiment provided by the present invention, the first dropping fixture mechanism group corresponds to points A1 to A5 in the above-mentioned diagonal operation instructions. The total width of the five first cantilevers 26 is the vertical projection width of points A1 to A5 (in the same direction as the width of the affiliated road). According to the corresponding parameters calculated by the above steps, the cone barrels 3 suspended by the five first cantilevers 26 are dropped in sequence from left to right.

[0149] Those skilled in the art should understand that both the partition structure and the top structure 22 adopt an approximately rectangular plate / block configuration and are arranged horizontally relative to the cargo box 1 and the vehicle body. In the embodiments of the present invention, the expressions "length", "width", "long side", and "wide side" are all referenced to the length and width directions of the cargo box 1 / vehicle body, that is, the front-back direction is the length direction, and the left-right direction is the width direction.

[0150] In the embodiment provided by the present invention, as Figure 1 shown, the first transmission chain structure includes a first track 23 suspended from the bottom surface of the top structure 22 and a conveyor chain 24 located below the first track 23; the first track 23 and the conveyor chain 24 are corresponding closed rectangular ring structures (with rounded corners at the four corners), and the first track 23 is in the configuration of an I-beam.

[0151] A pair of spaced roller ears 242 are provided on the top of multiple chain links 241 of the conveyor chain 24 for cooperation with the first track 23; the end of each roller ear 242 has a rolling wheel 243, and the rolling wheels 243 of each pair of roller ears 242 are respectively located on both sides of the I-beam configuration of the first track 23. As Fig. 9 shown, the first track 23 is in the layout of a regular I-beam. The rolling wheels 243 of each pair of roller ears 242 are respectively located on both sides of the I-beam configuration of the first track 23, and the peripheral surface of the rolling wheel 243 contacts the bottom two flanges of the I-beam of the first track 23. In this way, the conveyor chain 24 moves along the extension direction of the first track 23 through the rolling wheels 243. Since the conveyor chain 24 is formed by hinging the chain links 241, the roller ears 242 moving along the first track 23 have the functions of guiding the movement of the chain and preventing the conveyor chain 24 from derailing. The overall structure composed of the first track 23 and the roller ears 242 can also play a role in carrying the load below the conveyor chain 24.

[0152] The first transmission chain structure also includes a first drive motor 25, the output end of which has a drive gear meshing with the conveyor chain 24, and the drive gear is arranged horizontally. The first drive motor 25 can be suspended below the top structure 22, and its specific position can be appropriately set according to actual needs. Figure 7 As shown, in a feasible embodiment, a first driving motor 25 is arranged in the enclosed area of ​​the first track 23, and the driving gear is located on the wide side of the conveyor chain 24. Of course, two motors can also be arranged on opposite sides of each other. In this embodiment, driven gears 29 are provided at the four corners of the conveyor chain 24 located in the rectangular ring, which can reduce the friction between the roller ears 242 and the first track 23 when they move to the four corners, and improve the overall load distribution of the conveyor chain 24.

[0153] The delivery frame 2 also has a second delivery fixture mechanism group, including six second cantilevers 27, which are vertically suspended at the bottom of multiple chain links 241 of the conveying chain 24, and each second cantilever 27 has an electric claw 28 at the bottom end for grabbing, hanging and delivering the cone barrel 3. In a feasible embodiment, the second cantilever 27 is similar to the first cantilever 26, and both adopt a rigid columnar structure.

[0154] In the embodiment provided by the present invention, the electric claws 28 of the first cantilever 26 and the second cantilever 27 have the same structure, and have a pair of claw heads 281 and a rotating motor 282. The rotating motor 282 drives and connects the pair of claw heads 281 and can drive the pair of claw heads 281 to approach / move away from each other. Fig.14 As shown, the rotary motor 282 and the two claw heads 281 can be arranged in a herringbone shape, so that when the output end of the rotary motor 282 rotates, the claw heads 281 on the two sides below swing in opposite directions, thereby achieving clamping and loosening.

[0155] The control device is circuit-connected to the first delivery clamp mechanism group and the second delivery clamp mechanism group respectively, and based on the above-mentioned operation mode instruction, the claw heads 281 are driven away from each other by the rotating motor 282, so that the cone barrel 3 suspended at the bottom end of the first cantilever 26 and the second cantilever 27 falls to the road surface.

[0156] The position of the cone barrel is not only related to the parameters obtained in the above-mentioned steps of executing the operation mode instruction and the release timing of the first release fixture mechanism group, but also to the relative position of the second release fixture mechanism group in the release skeleton 2. In this embodiment, the second release fixture mechanism group corresponds to the above-mentioned point B3 to B1'. Since the connection line of the above-mentioned points is a straight line and is located on one side of the A1 to A5 line area that was released first, the long side of the frame 21 is selected as the release area. Since the long side of the frame 21 is shorter, a part of the second cantilever 27 is first transported to the long side of the frame 21 for sequential release, and then the remaining second cantilever 27 is transported to that side for continued release (such as Figure 1 and 8 shown). Figure 8 It is used to display the positional relationship between the first delivery fixture mechanism group and the second delivery fixture mechanism group in the delivery skeleton 2 when executing multi-linear layout instructions for single-vehicle or multi-vehicle collaboration. The figure uses suspended cone barrels 3 as an example. It can be seen from the figure that the group of five cone barrels 3 below is the first delivery fixture mechanism group, and the group with two cone barrels 3 on the side in the upper right corner and four cone barrels 3 on the top is the second delivery fixture mechanism group.

[0157] For example, in one embodiment, the specific process is as follows:

[0158] The conveyor chain 24 is driven to move by the first driving motor 25 so that the plurality of second cantilevers 27 of the second delivery fixture mechanism group are located at one side in the width direction of the top structure 22;

[0159] By controlling the rotating motors 282 of the plurality of second cantilevers 27 located on the side, the cone barrels 3 are sequentially placed on the road surface;

[0160] The conveyor chain 24 is driven to move by the first driving motor 25 so that the remaining second cantilevers 27 of the second delivery fixture mechanism group are located on the side of the top structure 22;

[0161] By controlling the rotating motor 282 of the second cantilever 27 on this side, the cone barrels 3 are dropped onto the road surface in sequence.

[0162] In an improved embodiment, the second cantilever 27 adopts an electric telescopic rod structure, which is used to lower the hanging height of the cone barrel 3 by extending the push rod downward before the cone barrel 3 is released, so as to better prevent the cone barrel 3 from tipping over. The specific structure is set as follows:

[0163] The second cantilever 27 includes a second cylinder and a second push rod which are fitted together. A second linear motor is fixedly installed on the side of the second cylinder. The second linear motor drives and connects the second push rod. The bottom end of the second push rod has the above-mentioned electric claw 28.

[0164] Correspondingly, in the process of the control device controlling the second delivery clamp mechanism group to deliver the cone barrel 3, before the step of controlling the rotating motor 282 of the second cantilever 27 located on one side in the width direction of the top structure 22 so that the cone barrel 3 is delivered to the road surface in sequence, it also includes: controlling the second linear motor of the second cantilever 27 located on this side so that the second push rod of the second cantilever 27 extends downward.

[0165] In another preferred embodiment provided by the present invention, the first delivery fixture mechanism group and the second delivery fixture mechanism group are both suspended on the top conveyor chain 24, and a cantilever with an electric telescopic rod structure is uniformly adopted. With the above arrangement, the execution of the operation mode instruction is completely realized through the station adjustment and delivery timing control of the first delivery fixture mechanism group and the second delivery fixture mechanism group. The specific scheme is as follows:

[0166] The traffic guide angle delivery device includes:

[0167] The cargo compartment 1 is arranged at the rear of the motor vehicle. In the present embodiment, the interior of the cargo compartment 1 can be used to store the cone barrel 3, so that the working vehicle becomes a special vehicle for placing the cone barrel.

[0168] The delivery skeleton 2 is used for delivering the cone barrel onto the road surface, and comprises a frame body 21 and a top structure 22 which are connected to each other; the frame body 21 is connected to the rear of the cargo compartment 1, and is open at the bottom; the bottom surface of the top structure 22 has a first transmission chain mechanism, and the first transmission chain structure comprises a first track 23 suspended on the bottom surface of the top structure 22, and a conveying chain 24 located below the first track 23; the first track 23 and the conveying chain 24 are closed rectangular ring structures corresponding to each other, and the first track 23 is an I-beam configuration.

[0169] A pair of roller ears 242 arranged at intervals are provided at the top of the multiple links 241 of the conveying chain 24 for matching with the first track 23; the end of each roller ear 242 has a rolling wheel 243, and the rolling wheels 243 of each pair of roller ears 242 are respectively located on both sides of the first track 23 of the I-beam configuration.

[0170] The first transmission chain structure further includes a first driving motor 25 . The output end of the first driving motor 25 has a driving gear meshing with the conveying chain 24 . The driving gear is arranged horizontally.

[0171] The delivery frame 2 also has a first delivery fixture mechanism group and a second delivery fixture mechanism group.

[0172] The first delivery fixture mechanism group includes five first cantilevers 26 vertically suspended at the bottom of the conveyor chain 24, such as Fig.13As shown, the first cantilever 26 includes a first cylinder 261 and a first push rod 262 which are fitted together. A first linear motor 263 is fixedly installed on the side of the first cylinder 261. The first linear motor 263 drives and connects the first push rod 262. The bottom end of the first push rod 262 has an electric claw 28 for grabbing, hanging and placing the cone barrel 3.

[0173] The second delivery fixture mechanism group includes six second cantilevers 27 vertically suspended at the bottom of the conveyor chain 24. The second cantilever 27 includes a second cylinder and a second push rod that are mutually nested. A second linear motor is fixedly installed on the side of the second cylinder. The second linear motor drives and connects the second push rod. The bottom end of the second push rod has an electric claw 28 for grabbing, hanging and delivering the cone barrel 3. As can be seen from the above description, the structure of the second cantilever 27 is the same as that of the first cantilever 26, so it is not shown in the drawings.

[0174] The electric claw 28 has a pair of claw heads 281 and a rotary motor 282 that is drivingly connected to the pair of claw heads 281 and can drive the pair of claw heads 281 to approach and move away from each other.

[0175] In this embodiment, the vertical projection of the long side area of ​​the conveyor chain 24 of the closed rectangular ring structure is located in the cargo compartment 1, so that the first delivery fixture mechanism group or the second delivery fixture mechanism group can be delivered to the cargo compartment 1 (the tail area). The above arrangement is used to supplement the cone barrel 3 to the first delivery fixture mechanism group or the second delivery fixture mechanism group, so as to achieve a wider range of operations.

[0176] In a feasible embodiment, the process of the first delivery fixture mechanism group or the second delivery fixture mechanism grabbing the cone barrel 3 includes:

[0177] The conveyor chain 24 is driven by the first driving motor 25 so that a first cantilever 26 or a second cantilever 27 is conveyed into the cargo compartment 1;

[0178] The first linear motor 263 or the second linear motor drives the first push rod 262 or the second push rod to extend downward;

[0179] The rotary motor 282 of the electric claw 28 of the first push rod 262 or the second push rod drives the claw head 281 of the electric claw 28 of the first push rod 262 or the second push rod to contact each other, so that the claw head 281 of the electric claw 28 of the first push rod 262 or the second push rod covers the lifting ring on the top of the cone barrel 3;

[0180] The first linear motor 263 or the second linear motor drives the first push rod 262 or the second push rod to reset;

[0181] The process of the first delivery fixture mechanism group or the second delivery fixture mechanism delivering the cone barrel 3 includes:

[0182] The first linear motor 263 or the second linear motor drives the first push rod 262 or the second push rod to extend downward;

[0183] The rotary motor 282 of the electric claw 28 of the first push rod 262 or the second push rod drives the claw heads 281 of the electric claw 28 of the first push rod 262 or the second push rod to move away from each other, so that the cone barrel 3 hanging on the electric claw 28 of the first push rod 262 or the second push rod falls;

[0184] The first linear motor 263 or the second linear motor drives the first push rod 262 or the second push rod to reset.

[0185] When the first cantilever 26 or the second cantilever 27 grabs the cone barrel 3, the distance that the first push rod 262 or the second push rod extends is calculated based on the difference between the relative height of the electric claw 28 and the relative height of the hanging ring 31 on the top of the cone barrel 3 in the cargo compartment 1, which can be called the first extension distance. When the first cantilever 26 or the second cantilever 27 drops the cone barrel 3, the distance that the first push rod 262 or the second push rod extends is also calculated in advance, and generally the maximum extension distance can be taken, which is called the second extension distance in this embodiment. In this embodiment, the second extension distance is preferably greater than the first extension distance.

[0186] In a feasible embodiment, the process of executing the above-mentioned oblique layout instruction includes:

[0187] By driving the first driving motor 25, the first delivery fixture mechanism group is transferred to the wide side of the top structure 22 (located at the wide side of the rear end of the vehicle), and at the same time, part of the second cantilever 27 of the second delivery fixture mechanism group is located at the long side of the top structure 22;

[0188] According to the corresponding parameters obtained by calculation, five cone barrels 3 suspended by the first cantilever 26 are released in sequence to complete the release operation at the A5 point of A1;

[0189] According to the corresponding parameters obtained by calculation, the cone barrels 3 suspended by the part of the second cantilever 27 on the side of the top structure 22 are sequentially dropped;

[0190] By driving the first drive motor 25, the remaining second cantilever 27 is transferred to the side of the top mechanism;

[0191] According to the corresponding parameters obtained by calculation, the remaining cone barrels 3 suspended by the second cantilever 27 are released in sequence to complete the release operation from point B3 to point B1'.

[0192] Since the process of delivering from B3 to B1' requires the corresponding second cantilever 27 to be transported, in order to ensure the continuity of delivery (without reducing the vehicle speed), a delivery and transport method can be adopted, that is, a position is set as a fixed delivery point, one is delivered, one is transported forward and then delivered, and so on.

[0193] In an improved embodiment, the cargo compartment 1 is configured as a dedicated storage and retrieval space for the cone barrel 3. The details are as follows:

[0194] like Figure 1 As shown, the cargo compartment 1 has a first space 11 and a second space 12, the second space 12 is located at the bottom of the cargo compartment 1, and the first space 11 and the second space 12 are separated from each other by a partition 15; the first space 11 is used to store the cone barrel 3, and the second space 12 has a cone barrel moving mechanism;

[0195] The cone barrel moving mechanism includes:

[0196] One or more groups of second transmission chain structures 13, each group of second transmission chain structures 13 is extended along the length direction of the second space 12; the partition 15 is provided with one or more through grooves 14, each through groove 14 is extended along the length direction of the partition 15; the toggle plates 131 are arranged at intervals on the chain of the second transmission chain structure 13; the toggle plates 131 located on the upper chain of the second transmission chain structure 13 extend into the first space 11 through the through grooves 14; when one or more cone barrels 3 are placed on the through grooves 14 and the second transmission chain structure 13 is driven, the toggle plates 131 extending into the first space 11 can push the cone barrels 3 located on the through grooves 14.

[0197] One side of the second transmission chain mechanism is adjacent to the tail of the cargo compartment 1 and corresponds to the conveyor chain 24 extending into the cargo compartment 1, so that the side is configured as a loading area for replenishing the cantilever with cone barrels 3. By executing the above-mentioned process of the first delivery clamp mechanism group or the second delivery clamp mechanism grabbing the cone barrel 3, the first delivery clamp mechanism group or the second delivery clamp mechanism can grab the cone barrel 3 transmitted to the side of the first transmission chain.

[0198] In one possible approach, Fig.11 As shown, the second transmission chain structure 13 adopts a double sprocket set structure, with a gear drive connected to the driving device (motor and reducer) on one side, i.e., the driving wheel, and a gear on the other side is a driven wheel. A toggle plate 131 is installed on the chain. The through groove 14 is a strip groove. The upper chains of the second transmission chain structure 13 are respectively adjacent to the through groove 14, so that the toggle plate 131 located on the upper chain of the second transmission chain structure 13 extends into the first space 11 through the through groove 14. The toggle plate 131 is arranged in this way so that it can toggle the cone barrel 3 to move when the chain is driven. It should be understood that the length of the through groove 14 should be greater than the total length of the sprocket and the toggle plates 131 on both sides, so that the end of the through groove 14 can leave a gap for the toggle plate 131 to be transmitted to the side of the gear. Fig.11 The structural style, positional relationship and working state of the second transmission chain structure 13 are exemplarily shown, and the arrow in the figure indicates the conveying direction of the cone barrel 3.

[0199] like Fig.12 As shown, guide rails 16 are provided on both sides of the through slot 14 to prevent the cone barrel 3 from deflecting during movement.

[0200] In an improved approach, Fig.12 As shown, two sets of second transmission chain mechanisms are provided in the second space 12, and two through grooves 14 are provided corresponding to the partition 15. Then two rows of cone barrels 3 can be stored in the first space 11. The longitudinal spacing (in the width direction of the cargo compartment 1) of the two rows of cone barrels 3 is adapted to the spacing of the adjacent first cantilever 26 or second cantilever 27 (equal spacing), so that the cone barrels 3 can be replenished for the two cantilevers at the same time.

[0201] The stop adjustment when the first transmission chain structure transmits the cantilever to the above-mentioned loading area can refer to the existing technology, for example, a photoelectric probe is installed at a preset position, and a cursor belt is correspondingly provided on the side of the cantilever, and the drive motor stop signal is fed back by identifying the cursor. When there are two sets of second transmission chain mechanisms, two photoelectric probes can be set, numbered respectively, and the control logic can be: probe No. 1 and probe No. 2 are set in sequence along the cantilever conveying direction; when the No. 1 probe identification signal is twice (referred to as 2), and the No. 2 probe identification signal is once (referred to as 1), it means that there are two cantilevers located in the loading area of ​​the two sets of second transmission chain mechanisms respectively, and the motor stop signal can be fed back and the cone barrel 3 grabbing operation can be performed at this time. If the No. 1 probe receives a signal of 1 and the No. 2 probe receives a signal of 0, it means that the cantilever has not been delivered to the position, and the transmission continues at this time to wait for further signal reception. If the No. 1 probe receives a signal of 1 and the No. 2 probe receives a signal of 2, it means that there is still one first cantilever 26 left in the first delivery fixture mechanism group that needs to supplement the cone barrel 3, and the grabbing operation of the first cantilever 26 is performed alone at this time. If the signal received by probe No. 1 is 0 and the signal received by probe No. 2 is 1, it means that the second delivery fixture mechanism group has completed the replenishment of the cone barrel 3, and the transmission operation of the second delivery fixture mechanism group is now performed.

[0202] By adopting the guide angle lane setting system set up as above, the cone barrel 3 can also be returned to its original position by reversely operating the first transmission chain structure, the first delivery clamp mechanism group, the second delivery clamp mechanism group and the second transmission chain mechanism (manual operation can be used to recover the cone barrel 3 from the road surface to the delivery clamp mechanism group).

[0203] It should be understood that the action timing of each mechanism of the delivery clamp mechanism can be uniformly controlled by the system's control device through programming based on existing technology, and integrated with the various mechanisms in the cargo compartment 1 to realize the cone barrel delivery and recovery functions of this system.

[0204] In some preferred embodiments, the cone barrel 3 used in the system has a corresponding counterweight at the bottom to prevent it from falling over when placed on the road surface. Fig.15 As shown, the top of the cone barrel 3 is provided with a hanging ring 31 for adapting to the clamping of the delivery clamp mechanism group.

[0205] In a preferred embodiment provided by the present invention, the process of the detection and evaluation device acquiring traffic condition information in real time, analyzing the acquired traffic condition information, and obtaining the work area safety notification information and / or warning information package includes:

[0206] Obtain real-time traffic flow information, vehicle speed information, and lane information of vehicles in the operation area;

[0207] Determine whether the traffic flow information within a certain time period exceeds the first preset threshold. If so, generate the first alarm information; otherwise, determine whether the speed of social vehicles exceeds the second preset threshold. If so, generate the second alarm information.

[0208] Among them, social vehicles refer to non-operating unit vehicles traveling on the road; the operating area includes the core area and adjacent areas of the operation. By obtaining traffic flow information of the entire area, the changing trend of traffic conditions can be judged. When the traffic flow is large, there are many vehicles on the road and the speed is slow. At this time, the first alarm information should be generated to inform the operating personnel on the vehicle to pay attention to traffic diversion, such as assigning corresponding personnel to divert traffic. When the traffic flow is small, the speed of a single social vehicle may be fast. At this time, it is necessary to pay special attention to fast vehicles traveling in the same lane as the operating vehicle, as well as other fast vehicles that exceed a certain judgment threshold, and generate a second alarm information to inform the operating personnel on the vehicle to pay special attention; when these vehicles approach the operating vehicle, a warning signal should be issued in time to prompt social vehicles to slow down and avoid in advance to prevent rear-end collisions or other accidents.

[0209] In other preferred embodiments, the system can be arranged on multiple working vehicles, for example, the control device is divided into a first controller and a second controller; the traffic guide angle delivery device, the detection and evaluation device, the laser projection guide angle device 4, and the first controller are arranged on the cone barrel 3 retracting vehicle, and the second controller is arranged on the anti-collision buffer vehicle. The first controller and the second controller can be communicatively connected so that the cone barrel 3 retracting vehicle and the anti-collision buffer vehicle are linked. The generation of road condition detection and alarm information can be implemented by the first controller and the second controller. In addition, there can also be multiple cone barrel 3 retracting vehicles, which together form an operating fleet, and are networked using vehicle networking technology to implement joint operations.

[0210] The system provided by the present invention can be provided with a corresponding operation panel in the cab or cargo compartment, including: a one-key confirmation delivery mode switch, a one-key return mode switch, a one-key confirmation operation start function (the corresponding program is pre-stored in the control device) and a one-key confirmation mechanism reset function; a control switch for each cantilever, and a status display light;

[0211] The display screen can display the status of the vehicle's surroundings in real time (there is a camera on the outside of the vehicle); it can also switch the displayed information, provide road condition analysis, work area location, etc.; it also has the function of temporarily cutting in warning information.

[0212] In summary, the present invention provides a traffic guide angle setting system based on real-time road conditions. It is a self-generated traffic guide angle system device designed based on real-time road conditions. The system device can be attached to various types of road occupying vehicles such as anti-collision vehicles, construction vehicles, patrol vehicles, engineering vehicles, police cars, tow trucks, etc. The traditional electromechanical and hydraulic systems are used to realize the self-stacking operation of the road guide angles. The virtual guide angle projection function is realized by laser projection to facilitate the recovery of the road guide angles. The on-board monitoring system can be used to observe the road conditions in real time, thereby realizing the non-stop stacking of temporary traffic guide angles, and realizing operations in different environments such as urban road scenes, rural road scenes, highway scenes, and local road scenes. Stacking and guiding operations for occupying lanes; the device is equipped with a real-time road condition system evaluation, which can analyze the driving conditions of the rear vehicle, determine the unsafe distance to the rear vehicle, issue a warning prompt, cooperate with the cone truck in front and connect in real time to maintain close operation communication and a safe distance; the device can carry 5 to 8 cones, and can generate a traffic guiding area of ​​no more than 35 meters. According to the prompt of the road condition evaluation system, the guiding angle generating device can be controlled by voice control or electromechanical buttons to achieve the placement of 5 to 8 guiding cones from left to right one by one, or the placement of some cones as needed, and can also be set to horizontal distribution or curved distribution as needed; at the same time, the empty space of the device can be replenished to complete the filling of cones at more points.

[0213] By installing a "self-generated traffic guide angle occupying system device based on real-time road conditions" behind the anti-collision buffer vehicle, when the cone vehicle starts to slow down to place the first safety helmet, the anti-collision buffer vehicle will simultaneously slow down to 30km / h~0km / h, and the device button will be turned to generate a guide angle triangular belt-shaped closed area similar to the upstream transition zone. Looking at the entire operation area, a double guide angle operation area can be formed.

[0214] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
