Technical Field

The invention relates to a transportation machine, in particular to a variable traffic marking device and application thereof.

Background

The continuous increase of the annual keeping quantity of automobiles particularly brings unprecedented pressure to urban road traffic. The scene that the vehicle is squeezed into a lump, the drivers are irritated and the horn sounds into a piece is almost a common part in daily life.

The congestion of the road brings great inconvenience to our life, and the pressure on dredging the road becomes one of the important research directions of the students in the traffic field. Research shows that there are many factors affecting traffic flow changes, but the influence of some of them is particularly important, including: commute time, holidays, etc.; in view of this feature, traffic researchers have proposed concepts including "tidal lanes" and "variable guide lanes" to make the allocation and utilization of traffic road resources more efficient, flexible and effective.

Taking tidal lanes as an example, since tidal lanes are gradually used in a plurality of cities in the 21 st century, the significance and effect of the tidal lanes are more and more recognized, and corresponding indication marks are increasingly diversified, such as: the ground indicating marked lines, the mobile road indicating lamps, the high-altitude indicating lamps and the like are mostly illuminated by LED lamps, so that limitation exists to a certain extent, traffic information is not convenient to confirm at any time in time, and corresponding traffic information or signals can be ignored when vehicles are too many or the vehicles are used all the time, so that potential safety hazards are brought to vehicle driving and road traffic.

Disclosure of Invention

In view of the needs of modern urban traffic and the problems existing in the prior art, the invention aims to disclose a variable traffic marking device and application thereof, the structural design is simple and reasonable, the installation is convenient, the use is convenient and efficient, and the wide application of the variable traffic marking device can bring benefits for solving urban traffic jam, vehicle traffic guidance and traffic efficiency including tidal lanes, variable guide lanes and the like.

The technical solution of the invention is realized as follows:

a variable traffic marking apparatus comprising:

a sealed housing having a light transmissive cover plate;

the display part is fixed in the sealed shell and displays traffic signals through the light-transmitting cover plate;

the control circuit is connected with the display part;

the display part comprises two groups of display units DA and DB; the two groups of display units form an included angle alpha and are arranged between a first position P1 and a second position P2Switching, corresponding to the two positions P1, P2, the included angles alpha are respectively alpha₁And alpha₂And α is₁=-α₂； 0<∣α∣<180º ；

In the P1 and/or P2 position state, the display unit DA is displaying right of way information M in a designated direction_aThe display unit DB displays right of way information M in a specified direction_b。

Further, the right of way information M_aAnd M_bAre the associated right of way information.

Due to the included angle alpha of the display units DA, DB at two positions P1 and P2₁And alpha₂The traffic marking device is equal in size and opposite in direction, the fact that the specified direction opposite to the DA and the DB is substantially the same as the corresponding coming direction of the corresponding road on which the traffic marking device is installed, and more exactly, the specified direction opposite to the display unit is the sight range of a driver corresponding to the coming direction.

Furthermore, each group of display units respectively comprises one or more than two display panels which are arranged in parallel, and the display panels in the two groups of display units are arranged in a crossed mode in sequence, namely, two adjacent display panels belong to different display units DA and DB; the adjacent display panels are connected end to end or slightly separated by a certain distance, and the included angle alpha is formed; the sides of all the display panels together form an inverted "V" shape (when each group of display units includes only one display panel, respectively) or a zigzag shape (when at least one group of display units includes two display panels).

More specifically, the display elements on the two groups of display units for displaying the right of way information are reflective materials and/or LED lamp group matrixes. For example, two groups of display units are respectively attached with green reflecting materials and red reflecting materials; alternatively, the display elements may be LED lamp sets, for example, two sets of display units are respectively provided with a green LED lamp set and a red LED lamp set; still alternatively, the display element may be a combination of reflective material and LED light sets, as desired.

Specifically, the display part comprises a motor and a transmission unit, and two ends of the transmission unit are respectively connected with the motor and the two groups of display units to realize the position conversion of the two groups of display units between a first position P1 and a second position P2.

More specifically, the display part includes a support structure for supporting or fixing the display unit. The arrangement of the supporting structure effectively improves and ensures the structural stability and the use reliability of the display unit. For example, the support structure may be a telescopic structure connected to both the display unit and the sealed housing, or also connected to the transmission unit.

Still further, the variable traffic marking unit further comprises a computer processor;

the control circuit and display are each coupled to the computer processor and configured to perform settings and actions in response to control by the computer processor.

The invention also discloses specific applications of the variable traffic marking device in road traffic, including the application of the variable traffic marking device to a tidal lane, or a variable guide lane and the like.

For example, the variable traffic marking device is applied to a tidal lane, and the variable traffic marking device is continuously or intermittently disposed on the center and/or side of the lane of the tidal lane.

In the state of the position P1 or P2, the specified directions opposite to the two groups of display units DA and DB are two opposite incoming directions of the tidal lane and are respectively positioned in the sight range of a driver in the corresponding incoming direction; when the two position states of P1 and P2 are converted, the specified direction in which the DA and DB are opposite is correspondingly converted;

specifically, the M_aFor right of way information indicating "permit of passage", M_bRight of way information indicating "no pass".

Specifically, for example, in the state of the position P1, the specified direction directly facing the display unit DA is the first incoming direction of the tidal lane and is located within the sight line of the driver in the first incoming direction, that is, the driver in the first incoming direction can just see the first incoming directionRight of way information M displayed on display unit DA_aAnd a driver of a second direction of approach of the tidal lane opposite the first direction of approach is unable to see the M_a(ii) a Meanwhile, the specified direction directly facing the display unit DB is the second coming direction and is located within the sight line range of the driver in the second coming direction, that is, the driver in the second coming direction can just see the right of way information M displayed on the display unit DB_bAnd the M is not visible to a driver of the first incoming direction opposite to the second incoming direction_b. When the angle of the display unit DA, DB is converted from alpha₁Conversion to alpha₂When the display unit is switched from the P1 position state to the P2 position state, the designated direction opposite to the DA is switched to the second incoming direction, and correspondingly, the incoming direction opposite to the DB is switched to the first incoming direction.

In this application, the change in relative angle (α) through the two sets of display elements₁<==>α_2）And finishing the display or indication of the corresponding right of way information. For example, the traffic sign device of the tidal lane is used for displaying or indicating the right of way of vehicles running in opposite directions in different periods, that is, the specified directions opposite to the display unit respectively correspond to two incoming directions (or the sight line range of the driver in the incoming directions). The display elements on the display units can be made of reflecting materials, for example, green reflecting materials and red reflecting materials are respectively attached to two groups of display units; alternatively, the display elements may be LED lamp sets, for example, two sets of display units are respectively provided with a green LED lamp set and a red LED lamp set; still alternatively, the reflective material and the LED light set may be installed simultaneously. Under the working state, when the two groups of display units form an included angle alpha₁When the user arrives, the display unit DA faces the first direction of the coming vehicle and displays green, the 'permission to pass' and the right of pass information M_aRespectively form an included angle alpha with it₁Towards a second direction of arrival (which is exactly opposite to the first direction of arrival) and displays in synchronism red- "no pass" -right of way information M_b(ii) a Further, at the set timeThe right of way information towards the same direction of the coming vehicle needs to be changed, namely, according to the setting and the control of the control circuit, the two groups of display units synchronously or approximately synchronously turn over, and the included angle between the two groups of display units is changed from alpha₁Becomes alpha₂（α₂=-α₁) Then, the display unit DB facing the first coming direction displays red-no-pass-right-of-pass information, and the corresponding display unit DA (DA and DB form an included angle alpha)₂) Towards the second direction of arrival and displaying green- "allow pass" -right of way information. Here, the two groups of display units or display panels constituting the display units are turned "close to synchronously" means that turning actions of the two groups of display units have a sequence in order to ensure that the two groups of display units or the display panels thereof are not pushed to the top and are not locked during turning, or in order to avoid and reduce collision between the two groups of display units as much as possible and further ensure structural stability and accuracy of indication direction, but at the same time, the traffic indication is broken as much as possible in consideration of the safety of traffic indication, and especially, the traffic signal collision is absolutely avoided; in view of the above requirements and considerations, the sequential turning of the two groups of display units not only needs to consider who is first and then, but also needs to consider the continuity of the turning and the reasonability and safety of time interval design, so as to ensure that the sequential turning is close to synchronization. More specifically, the display part further comprises a motor and a transmission unit, two ends of the transmission unit are respectively connected with the motor and the two groups of display units to realize linkage of the two groups of display units within a specified time so as to complete the included angle alpha₁And alpha₂A transition between, which may include a planned transition or a temporary transition.

As another example, the variable traffic marking device is applied to a variable guide lane, and particularly, the variable traffic marking device is continuously or intermittently disposed on the center and/or side of the lane of the tidal lane;

in the state of the position P1, the specified direction opposite to the display unit DA is the coming direction of the variable guide lane and is positioned in the sight range of the driver in the coming direction, and the specified direction opposite to the display unit DB is not positioned in the sight range of the driver in any coming direction; when the two position states of P1 and P2 are converted, the specified direction in which the DA and DB are opposite is correspondingly converted;

the M is_aAnd M_bRespectively represent two types of right-of-way information allowed by the variable guide lane.

When the traffic marking device is applied to a tide lane or a variable guide lane, the traffic marking device can be buried or embedded on the ground of the corresponding lane or appropriate facilities beside the lane, such as guardrails or isolating screens at the roadside and the like according to the characteristics of the specific lane, and the display part of the traffic marking device can be ensured to clearly fall into the sight line of a driver in the corresponding incoming direction.

Displaying corresponding right-of-way information or signals at corresponding positions of the tidal lane or in the whole range according to the preset incoming direction corresponding to the specified direction at corresponding time or occasion; of course, the invention also reserves the condition that the temporary management and display of the right of way information or signals can be realized on site or remotely under specific conditions. The arrangement of the computer processor and even the addition of the network system can ensure that the application of the invention has the characteristics of wider and more extensive flexibility, intelligence, timeliness and high efficiency.

Compared with the prior art, the invention has simple and reasonable structural design and convenient and flexible use and arrangement, can be widely applied to the tide lane and the variable guide lane, can be continuously arranged or arranged in a point-to-point manner according to the specific road condition and the traffic signal indication requirement, is particularly convenient for a driver to master traffic information or signals at any time and in time, and effectively ensures that roads including the tide lane and the variable guide lane and the like pass and use efficiently and safely; and provides a new idea and direction for the safe and smooth urban traffic from the aspect of hardware facilities.

Detailed Description

The technical solution of the present invention will be described more clearly and completely with reference to the accompanying drawings.

It is to be understood that the following examples are only some, but not all, of the present invention. On the basis of the following examples, any person skilled in the art can substitute or change the technical solutions according to the present invention without inventive work, within the technical scope disclosed in the present invention, and shall be covered within the protection scope of the present invention.

Example 1

A variable traffic marking apparatus 1, as shown in fig. 1-4, the traffic marking apparatus 1 comprising:

the device comprises a sealed shell 10, a light plate 11, a control circuit board 13, a supporting structure 14 and a motor 15; the light plate 11 is attached with red or green reflecting material 16 to form a display panel, a plurality of display panels parallel to each other form a group of display units, and the display part of the variable traffic marking device 1 comprises two groups of display units.

In general, the housing 10 may be a hollow three-dimensional structure with an open upper end, which is formed by four side plates and a bottom plate, which are arranged opposite to each other, so that a receiving space is formed inside the housing 10, and the receiving space is used for receiving the light plates 11, the control circuit board 13, the supporting device 14, the motor 15, and other components, as shown in fig. 3 and 4. The upper surface of the sealed shell 10 is a light-transmitting cover plate 12, and is sealed by waterproof sealing cement to prevent internal water inlet short circuit or pollution; when installed on the ground, the upper surface of the light-transmitting cover plate 12 is generally flush with the road surface. Specifically, the control circuit board 13 may be fixed on a side plate of the housing 10, for example, the control circuit board 13 may be directly welded or adhered to a bottom plate of the housing 10, or the control circuit board 13 may be detachably mounted on the bottom plate of the housing 10 by screws or fasteners, etc. The support structure 14 may be fixed to the bottom and side panels of the housing 10, and may be removably mounted by welding, adhesive, screws, or snaps.

As described above, the surfaces of the two sets of light plates 11 are respectively adhered with red and green reflective materials to form two sets of display units, which are integrally zigzag when viewed from the side, as shown in fig. 1 and 3: the mutually parallel lightweight boards 11 (the surfaces of which are adhered with the reflective materials 16 and jointly form a display board) belong to a group of display units, so that right of way information or signals are displayed in a specified direction; the light plates in the two groups of display units are arranged in a crossed manner in sequence, namely, two adjacent light plates respectively belong to different display units; the adjacent light boards are connected end to end or slightly separated by a distance, and an included angle alpha is formed, wherein 0< | alpha <180 degrees. A through hole is preset in the middle of the light plates 11, a gap is reserved on one side of each light plate for placing a motor 15, the supporting structure 14 is used for supporting and fixing the light plates or the display units and connecting the motors 15 and the transmission units to realize the angle and position transformation of the two groups of light plates 11 or the display units; in order to prevent the light plates from being jammed during angle conversion, a certain gap is usually left between the adjacent light plates 11.

Compared with the traditional plane structure, the two groups of display units of the traffic marking device 1 form an included angle alpha, and a three-dimensional structure is formed based on the included angle alpha, as shown in fig. 1 and fig. 3, the structure aims at the sight line or the visual field of a driver, and particularly under the condition of large daytime illumination intensity, the interference degree of the structure by external light is smaller than that of the plane lamp structure, and people can see light signals reflected by the three-dimensional structure more clearly; in addition, due to the influence of the angle, people can receive the optical signal emitted by the three-dimensional structure at a longer distance, so that the three-dimensional structure has the advantages of being larger than that of the existing plane marking device, and furtherSo that the driver and the like can have more time to make corresponding reaction according to the received optical signal. When the traffic marking device 1 is disposed on the white color mark line of the tidal lane, as shown in fig. 5, the display panels or light panels 11 of the two groups of display units are respectively oriented to the driving direction of the bidirectional driving vehicle, so that drivers in two directions can respectively obtain different right-of-way information or signals from the visual field of the driving direction. When the vehicle comes in the direction consistent with the current allowed passing direction of the tidal lane, the angle of the two groups of display units is set as alpha₁Only the light plate 11 attached with green reflecting material can be seen from the driving direction, namely the traffic right information, namely 'permission to pass'; the driver of the oncoming vehicle in the next lane sees the light plate made of red reflecting material, and the right-of-way information of 'no-way' is obtained. When the right of way of the tidal lane is changed in a specified time period, under the control of the control circuit board 13, the motor 15 is connected with the transmission unit to drive the support structure 14 and the corresponding light plate 11 to rotate for a specified angle, namely, the included angle between the two groups of display units is alpha₁Transformation to alpha₂And α is₂=-α₁(ii) a Thereby, the corresponding right of way information of the tidal lane is converted. Thereby, the safety indication and the energy-efficient passing of the tidal lane can be realized.

In addition, based on the traffic sign device 1 with such a structure, the display elements thereof may also use a matrix of red and green LED lamp groups, either individually or simultaneously.

Besides, the length, width and the size of the angle a formed by the light boards 11 can be set according to actual requirements and application scenarios. The light plate 11 can be controlled to rotate by the control circuit board 13, so that the traffic signal conversion is realized. The light plate attached with the red reflector is used as one group of display units DA, the light plate attached with the green reflector is used as the other group of display units DB, the problem that jamming and the like occur in the process of simultaneous rotation of the two groups of display units is solved, generally, the DB is controlled to rotate firstly through the control circuit board 13, after the DB rotates in place, the DA is controlled to rotate through the control circuit board 13, and the DA and the DB are sequentially rotated to avoid the collision or jamming of the two groups of display units in the action process. The display principle of the two directions after the transformation is the same as that before the transformation, and the display color is opposite to that before the transformation, which is not repeated.

Example 2

A variable traffic marking device 1, which has substantially the same structure as that of embodiment 1, and since it is applied to a variable guide lane, for example, a lane which can be left-turned only in one period and can be left-turned and straight-going in another period, the variable traffic marking device 1 is different from embodiment 1, and mainly comprises:

since the variable guide lane has only one incoming direction, the right of way information M displayed by a set of display units DA of the traffic marking device 1_aA mark of 'left turn only', and right of way information M displayed by another group of display units DB_b"Can turn left and go straight at the same time". In this way, when the two sets of display units are in the state of their P1 positions, the display unit DA faces the incoming direction of the variable guide lane and enables the driver in the incoming direction to obtain the corresponding right of way information M from the field of view in the driving direction of the driver_a(can only turn left) and forms an included angle alpha with the left₁Is not within the range of the driver's sight in either direction of the incoming vehicle, for example, when the variable traffic marking device 1 is buried in the lane of the lane, the DB may face the ground in the state of P1. Similarly, when the display units are in the position state of P2, the included angle between the two groups of display units is changed to alpha₂（α₂=-α₁) The display unit DB faces the coming direction of the variable guide lane and enables the driver of the coming direction to acquire the corresponding right of way information M from the view of the driving direction_b(it can turn left and go straight at the same time), the corresponding display unit DA turns to face the ground.

Similarly, the traffic sign device 1 may also use a matrix of red and green LED sets as its display elements, or a reflector may be used in conjunction with the matrix of LED sets.

With the development of computer automation control, the variable traffic marking device may further comprise a computer processor; the control circuit and display portion (including display unit, support structure, transmission unit, etc.) are coupled to the computer processor and configured to perform settings and actions in response to control of the computer processor to accomplish the display and conversion of the right of way information.
