Description

Technical Field

[0001] The present invention relates to the technical field of tidal lanes, and in particular to a vehicle-road cooperative sensing magnetic induction vehicle diversion device for a tidal lane. Background Art

[0002] Tidal lanes are lanes on road sections that can change the direction of vehicle travel according to traffic flow requirements. In cities, one or more lanes with vehicle travel directions that change at different times are set for roads with conditions according to different traffic flow conditions in the morning and evening. The driving direction on tidal lanes is usually fixed in a certain time period. For example, during the morning rush hour and the evening rush hour, the driving direction on tidal lanes is opposite; or the position of water barriers on the lanes is controlled by special control vehicles to achieve control of the driving direction of tidal lanes. The operating speed of this method is 5 km-10 km / h, which is slow. Therefore, the traditional driving direction control method of tidal lanes cannot adjust the driving direction in a timely and rapid manner according to the road traffic conditions. It has poor timeliness and is difficult to effectively alleviate traffic congestion in a timely manner. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a vehicle-road cooperative sensing magnetic induction vehicle diversion device for a tidal lane, which solves the problem that the traditional driving direction control method of a tidal lane cannot adjust the driving direction in a timely and rapid manner according to the road traffic conditions, and it is difficult to effectively alleviate traffic congestion in a timely manner.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A vehicle-road cooperative sensing magnetic induction vehicle diversion device for a tidal lane comprises a lane 1 arranged on a road surface, and a lane 2 which is opposite to the vehicle driving direction specified by the lane 1, a tidal lane divided by a double yellow line is arranged between the lane 1 and the lane 2, and a magnetic induction mechanism for sending the tidal lane traffic status and distance information to the vehicle is laid in the road surface;

[0006] The magnetic induction mechanism includes a magnetic induction module one for sending magnetic signal one to the tidal lane and vehicles in lane one, and also includes a magnetic induction module two for sending magnetic signal two to the tidal lane and vehicles in lane two. The magnetic signal one and magnetic signal two contain the traffic status and traffic distance information of the tidal lane. A signal receiving module for receiving magnetic signal one and magnetic signal two is arranged in the vehicle on the road surface.

[0007] Preferably, the magnetic induction module 1 and the magnetic induction module 2 are used to generate a magnetic field in which several groups of magnetic poles can be independently controlled, and the magnetic signal 1 and the magnetic signal 2 are formed by arranging the magnetic poles at one end of several groups of magnetic fields according to the direction of vehicle travel.

[0008] Preferably, the magnetic induction module 1 and the magnetic induction module 2 have the same structure, and the magnetic induction module 1 includes a plurality of DC coils and a current commutator for supplying power to the DC coils.

[0009] Preferably, the direction from the N pole to the S pole of the magnetic field generated by the DC coil is perpendicular to the ground, and the DC coil is flat in shape.

[0010] Preferably, the number of the magnetic fields is at least 3.

[0011] Preferably, the magnetic signal one and the magnetic signal two include two first magnetic field groups located at their ends for displaying the traffic status of the tidal lane, and also include a second magnetic field group for displaying the remaining distance of the tidal lane.

[0012] Preferably, the magnetic induction module 1 and the magnetic induction module 2 are distributed along the tidal lane at a certain distance.

[0013] Preferably, the magnetic induction module 1 and the magnetic induction module 2 are respectively located at the double yellow lines on both sides of the tidal lane.

[0014] Preferably, the signal receiving module is a vehicle-mounted Gauss meter or a Hall magnetic field identification instrument installed in the vehicle.

[0015] Compared with the prior art, the present invention provides a vehicle-road cooperative sensing magnetic induction vehicle diversion device for tidal lanes, which has the following beneficial effects:

[0016] 1. By setting up a magnetic induction mechanism, using magnetic signals 1 and 2 emitted by the magnetic induction mechanism, the traffic information of the tidal lane is represented, and vehicles are guided to drive into the tidal lane. This method can adjust the driving direction of the tidal lane at any time, changing the problem of the single driving direction of the traditional tidal lane at fixed time periods. Compared with special control vehicles controlling lane water barriers to change the driving direction, this method saves manpower and material resources, and reduces the area occupied by water barrier traffic accessories on the road.

[0017] 2. By setting up a magnetic induction mechanism and a current commutator, the current direction in the DC coil is changed to change the direction of the magnetic field, thereby changing the magnetic pole signal, that is, changing the driving direction of the tidal lane. Compared with the traditional method in which the driving direction of the tidal lane is fixed and cannot be adjusted within a certain period of time or the adjustment speed is slow, this method can quickly adjust the driving direction of the tidal lane according to the traffic congestion in different directions of the road surface, and timely divert the congested sections, thus overcoming the problem of traffic congestion caused by untimely adjustment of traditional variable lanes.

[0018] 3. By setting the DC coil to a flat shape and burying it between the upper layer and the middle layer, compared with the traditional spring-shaped DC coil, it is not easy to be damaged under the load of the vehicle and will not affect the road performance of the road surface.

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] The development of assisted driving technology has become one of the important strategic directions in my country's transportation field. By continuously enhancing the intelligence of the transportation system and creating a road traffic system that matches modern transportation needs, the storage and transmission of road traffic information through magnetic coding units can effectively assist the automatic driving of vehicles. However, traditionally, magnetic materials (neodymium magnets, etc.) are usually buried in the road surface to serve as magnetic units to guide vehicles. However, the magnetic poles of these magnets are fixed, that is, the magnetic numbers they carry are single and cannot be changed. They cannot be used to store and transmit traffic information with multi-functional and multi-directional lanes, nor can they effectively guide vehicles on these roads, and it is difficult to adjust the driving direction in tidal lanes in a timely and rapid manner.

[0026] In order to solve the problem that the driving direction control method of the traditional tidal lane cannot adjust the driving direction in time and quickly according to the road traffic conditions, and it is difficult to timely and effectively alleviate traffic congestion, the present invention provides a vehicle-road cooperative sensing magnetic induction vehicle diversion device for a tidal lane, comprising a lane 1 arranged on the road surface, and a lane 2 2 opposite to the vehicle driving direction specified by the lane 1, a tidal lane 3 divided by a double yellow line is arranged between the lane 1 and the lane 2 2, and a magnetic induction mechanism 4 for sending the traffic status and distance information of the tidal lane 3 to the vehicle is laid in the road surface, and the magnetic induction mechanism 4 interacts with the vehicle to inform the vehicle whether it can enter the tidal lane 3 and the remaining distance of the tidal lane 3, so that the vehicle has sufficient time to change lanes to the normal driving lane;

[0027] The magnetic induction mechanism 4 includes a magnetic induction module 1 41 for sending magnetic signal 1 to vehicles in the tidal lane 3 and lane 1, and also includes a magnetic induction module 2 42 for sending magnetic signal 2 to vehicles in the tidal lane 3 and lane 2 2. The magnetic signal 1 and the magnetic signal 2 contain the traffic status and travel distance information of the tidal lane 3. The vehicle on the road is provided with a signal receiving module 43 for receiving the magnetic signal 1 and the magnetic signal 2. The background management system adjusts the allowed vehicle driving direction in the tidal lane according to the traffic volume and traffic direction on the road, thereby being able to adjust the traffic volume allowed in the two direction lanes on the road to alleviate traffic congestion problems, and the vehicle can know the remaining distance of the tidal lane, so that the driver can control the vehicle to change lanes to the normal driving lane in time.

[0028] In order to ensure that the magnetic signal one and the magnetic signal two generated by the magnetic induction module one 41 and the magnetic induction module two 42 are simpler and more effective, the magnetic induction module one 41 and the magnetic induction module two 42 are used to generate a magnetic field in which several groups of magnetic poles can be independently controlled. The magnetic signal one and the magnetic signal two are formed by several groups of magnetic poles at one end of the magnetic field arranged according to the direction of vehicle travel. In actual use, for example, 5 magnetic fields are set, and the magnetic poles at one end of the magnetic field are obtained to form a magnetic signal one and a magnetic signal two such as NNNNN.

[0029] In order to ensure that the magnetic field is generated in a simpler, more durable and effective manner, the life of the device generating the magnetic field is required to match the life of the road. The magnetic induction module 1 41 and the magnetic induction module 2 42 have the same structure. The magnetic induction module 1 41 includes a plurality of DC coils 411 and a current commutator 412 for supplying power to the DC coils 411. The current commutator 412 can change the direction of the current in the DC coil 411, thereby changing the magnetic poles at both ends of the DC coil 411.

[0030] The magnetic poles generated on both sides of the DC coil 421 are opposite. In order to ensure the stability and accuracy of the signal receiving module 43 when detecting the magnetic pole, the magnetic pole that needs to be detected by the DC coil 421 is closest to the signal receiving module 44. Therefore, the direction from the N pole to the S pole of the magnetic field generated by the DC coil 411 is perpendicular to the ground, and the DC coil 421 is flat in shape and buried between the upper layer and the middle layer. Compared with the traditional spring-shaped DC coil 421, it is not easily damaged under the action of vehicle load and will not affect the road performance of the road surface.

[0031] In order to enable magnetic signal 1 and magnetic signal 2 to display the remaining distance when tidal channel 3 is passable, incommunicable, and communicable, there are three states. Since there are two magnetic poles, the number of magnetic fields needs to be at least three.

[0032] In order to more clearly display the encoding method of magnetic signal one and magnetic signal two, magnetic signal one and magnetic signal two include two first magnetic field groups located at their ends for displaying the pass status of tidal lane 3, and also include a second magnetic field group for displaying the remaining distance of tidal lane 3. Taking 5 magnetic fields as an example, the two magnetic fields at the ends of magnetic signal one and magnetic signal two, that is, the first magnetic field group, can be encoded as NN, SS and NS / SN, and NN and SS can represent the passable and impassable states of the tidal lane respectively. When it is NS or SN, that is, the two magnetic poles are different, it is a passable state and the subsequent second magnetic field group encoding is read. At this time, the other three magnetic fields, that is, the second magnetic field group encoding such as "NNN", "NNS", "NSN", "NSS", "SNN", "SNS", "SSN" and "SSS" can respectively indicate that there are 400m, 350m, 300m, 250m, 200m, 150m, 100m and 50m remaining to the end of the tidal lane.

[0033] The magnetic induction module 1 41 and the magnetic induction module 2 42 need to be distributed along the tidal lane 3. The magnetic induction module 1 41 and the magnetic induction module 2 42 are distributed along the tidal lane 3 at a certain distance. Generally, the distance is set to 50m. Depending on the vehicle speed, for some areas with slower vehicle speeds, the distance can be shortened on the basis of 50m, and for some areas with faster vehicle speeds, the distance can be increased on the basis of 50m.

[0034] Since the signal receiving module 43 has a limited range for detecting the magnetic field, in order to enable the tidal lane 3 and the adjacent lane to clearly detect magnetic signal one and magnetic signal two, the magnetic induction module one 41 and the magnetic induction module two 42 are respectively located at the double yellow lines on both sides of the tidal lane 3, so that the distances from the magnetic induction module one 41 and the magnetic induction module two 42 to the vehicles in the two adjacent lanes are equal.

[0035] The signal receiving module 43 needs to be able to detect the magnetic signal 1 and the magnetic signal 2 when the vehicle is in motion. The signal receiving module 43 is a vehicle-mounted Gauss meter or a Hall magnetic field identification instrument installed in the vehicle.

[0036] Taking the example that magnetic signal 1 and magnetic signal 2 are composed of magnetic pole codes corresponding to 5 magnetic fields, when the traffic volume in lane 1 is large and needs to be diverted to tidal lane 3, the DC coil 411 in the magnetic induction module 41 is connected to current, and the current direction of the DC coil is changed through the current commutator 412, and its magnetic field signal is "NNNNN". Similarly, in the magnetic induction module 41 within 400m of the end of the tidal lane, the current direction of the DC coil 411 is changed through the current commutator 412, thereby changing the magnetic pole of the magnetic field and displaying the remaining distance of the tidal lane 3. At this time, the magnetic induction module 1 42 between lane 2 and tidal lane 3 is also connected with current, and the direction of the DC coil current is changed through the current commutator. The magnetic field signals are all "SSSSS". At this time, the signal receiving module 43 of the vehicle on lane 1 recognizes the passable signal of the auxiliary driving device 1, and guides the vehicle to change lanes to tidal lane 3 and pass through tidal lane 3. At the same time, the vehicles on lane 2 recognize the no-passing signal issued by tidal lane 3 received by the signal receiving module 43, preventing the vehicles on lane 2 from changing lanes and entering the tidal lane.
