A vehicle-road cooperative sensing magnetic induction vehicle diversion device for tidal lanes

Abstract

This invention relates to the field of tidal flow lane technology, specifically a vehicle-road cooperative sensing magnetic guidance vehicle diversion device for tidal flow lanes. Through a magnetic guidance mechanism, magnetic signals one and two emitted by the mechanism characterize the traffic information of the tidal flow lane. A current commutator changes the direction of the current in the DC coil, causing a change in the magnetic field direction, thereby altering the magnetic pole signal and thus the driving direction of the tidal flow lane. This guides vehicles into the tidal flow lane. This method allows for adjustment of the driving direction of the tidal flow lane at any time, overcoming the problem of a fixed driving direction in traditional tidal flow lanes. Compared to using special control vehicles to control water-filled barriers to change driving direction, this method reduces the encroachment of water-filled barriers on the road surface. It solves the problem that traditional tidal flow lane driving direction control methods cannot adjust the driving direction promptly and quickly according to road traffic conditions, making it difficult to effectively alleviate traffic congestion.

Description

Technical Field

[0001] This invention relates to the field of tidal flow lane technology, specifically to a vehicle-road cooperative sensing magnetically induced vehicle diversion device for tidal flow lanes. Background Technology

[0002] A tidal flow lane is a lane on a road that allows vehicles to change their direction of travel according to traffic flow demand. Within cities, based on different traffic volumes during the morning and evening, one or more lanes are designated on suitable roads with lanes whose direction of travel changes with the time of day. The direction of travel in a tidal flow lane is usually fixed for a certain period, such as during the morning and evening rush hours when the directions are opposite. Alternatively, special control vehicles can be used to control the position of water-filled barriers in the lane to control the direction of travel. This method operates at a speed of 5-10 km / h, which is relatively slow. Therefore, traditional methods of controlling the direction of travel in tidal flow lanes cannot adjust the direction of travel promptly and quickly according to road traffic conditions, resulting in poor timeliness and difficulty in effectively alleviating traffic congestion. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a vehicle-road cooperative sensing magnetic guidance vehicle diversion device for tidal lanes. This solves the problem that traditional tidal lane driving direction control methods cannot adjust driving direction in a timely and rapid manner according to road traffic conditions, making it difficult to effectively alleviate traffic congestion.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A vehicle-road cooperative sensing magnetic guidance vehicle diversion device for tidal lanes includes a lane one set on the road surface and a lane two opposite to the vehicle travel direction specified by lane one. A tidal lane separated by double yellow lines is set between lane one and lane two. A magnetic guidance mechanism for sending tidal lane traffic status and distance information to vehicles is laid in the road surface.

[0006] The magnetic induction mechanism includes a magnetic induction module 1 for sending magnetic signal 1 to vehicles in the tidal flow lane and lane 1, and a magnetic induction module 2 for sending magnetic signal 2 to vehicles in the tidal flow lane and lane 2. The magnetic signal 1 and magnetic signal 2 contain information on the tidal flow lane traffic status and travel distance. Vehicles on the road are equipped with signal receiving modules for receiving magnetic signal 1 and magnetic signal 2.

[0007] Preferably, the magnetic induction module one and magnetic induction module two are used to generate several sets of magnetic fields with independently controllable magnetic poles. Magnetic signal one and magnetic signal two are formed by arranging the magnetic poles at one end of several sets of magnetic fields according to the vehicle's driving direction.

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

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

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

[0011] Preferably, the magnetic signal one and 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 one and magnetic induction module two are distributed at a certain distance along the direction of the tidal lane.

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

[0014] Preferably, the signal receiving module is an on-board gaussmeter or a Hall magnetic field detector installed in the vehicle.

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

[0016] 1. By using the magnetic induction mechanism, the magnetic signals emitted by the mechanism are used to characterize the traffic information of the tidal flow lane and guide vehicles to enter the tidal flow lane. This method can adjust the driving direction of the tidal flow lane at any time, which changes the problem of the single driving direction of the traditional tidal flow lane at a fixed time. Compared with the special control vehicle controlling the water-filled barriers in the lane to change the driving direction, this method saves manpower and resources and reduces the encroachment of water-filled barriers on the road area.

[0017] 2. By using a magnetic induction mechanism and a current commutator to change the direction of the current in the DC coil, the direction of the magnetic field is changed, thereby altering the magnetic pole signal and thus changing the driving direction of the tidal flow lane. Compared to traditional methods where the driving direction of the tidal flow lane is fixed and cannot be adjusted for a certain period of time or the adjustment speed is slow, this method can quickly adjust the driving direction of the tidal flow lane according to the traffic congestion situation in different directions of the road, and promptly divert traffic from congested sections, overcoming the problem of traffic congestion caused by the untimely adjustment of traditional variable lanes.

[0018] 3. By setting the DC coil to a flat shape and embedding it between the upper and middle layers, compared with the traditional spring-shaped DC coil, it is not easily damaged under vehicle load and will not affect the road performance of the road surface. Attached Figure Description

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

[0025] The development of driver assistance technology has become one of the important strategic directions in my country's transportation sector. By continuously enhancing the intelligence of the transportation system, a road traffic system that matches modern transportation needs can be created. Currently, storing and transmitting road traffic information through magnetic coding units can effectively assist in the autonomous driving of vehicles. However, traditionally, magnetic materials (such as neodymium magnets) are usually embedded in the road surface to guide vehicles. However, the magnetic poles of these magnets are fixed, meaning that the magnetic signal they carry is single and unchangeable. This makes it impossible to use them for storing and transmitting traffic information in multi-functional, multi-directional lanes, and it is also impossible to effectively guide vehicles on these roads, making it difficult to adjust the driving direction in tidal lanes in a timely and rapid manner.

[0026] To address the problem that traditional tidal flow lanes cannot adjust their driving direction promptly and quickly according to road traffic conditions, thus failing to effectively alleviate traffic congestion, this invention provides a vehicle-road cooperative sensing magnetic guidance vehicle diversion device for tidal flow lanes. The device includes a lane 1 on the road surface and a lane 2 opposite to the driving direction specified by lane 1. A tidal flow lane 3, separated by double yellow lines, is provided between lane 1 and lane 2. A magnetic guidance mechanism 4 is laid in the road surface to send information on the traffic status and distance of the tidal flow lane 3 to vehicles. The magnetic guidance mechanism 4 interacts with vehicles, informing them whether they can enter the tidal flow lane 3 and the remaining distance of the tidal flow lane 3, thus allowing vehicles sufficient time to change lanes to the normal driving lane.

[0027] The magnetic guidance mechanism 4 includes a magnetic guidance module 41 for sending magnetic signal 1 to vehicles in the tidal flow lane 3 and lane 1, and a magnetic guidance module 42 for sending magnetic signal 2 to vehicles in the tidal flow lane 3 and lane 2. Magnetic signal 1 and magnetic signal 2 contain information on the traffic status and travel distance of the tidal flow lane 3. Vehicles on the road are equipped with signal receiving modules 43 for receiving magnetic signal 1 and magnetic signal 2. The background management system adjusts the allowed vehicle travel direction in the tidal flow lane according to the traffic flow and direction on the road, thereby regulating the allowed traffic flow in the two lanes in the road to alleviate traffic congestion. Vehicles can also know the remaining distance of the tidal flow lane, so that drivers can control their vehicles to change lanes to the normal driving lane in time.

[0028] To ensure that the magnetic signals 1 and 2 generated by the magnetic induction module 1 41 and the magnetic induction module 2 42 are simpler and more effective, the magnetic induction module 1 41 and the magnetic induction module 2 42 are used to generate several sets of magnetic fields with independently controllable magnetic poles. The magnetic signals 1 and 2 are formed by arranging the magnetic poles at one end of several sets of magnetic fields according to the vehicle's driving direction. In actual use, for example, if 5 magnetic fields are set, the magnetic poles at one end of the magnetic field can be used to form magnetic signals 1 and 2 such as NNNNN.

[0029] To ensure that the magnetic field generation method is simpler, more durable and more effective, the lifespan of the magnetic field generation device must match the lifespan of the road. Magnetic induction module 1 41 and magnetic induction module 2 42 have the same structure. Magnetic induction module 1 41 includes several 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 coils 411, thereby changing the magnetic poles at both ends of the DC coils 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 poles, the magnetic poles that need to be detected by the DC coil 421 need to be as close as possible to the signal receiving module 44. Therefore, the direction of the magnetic field generated by the DC coil 411 from the N pole to the S pole is perpendicular to the ground. The DC coil 421 is flat and is buried between the upper layer and the middle layer. Compared with the traditional spring-shaped DC coil 421, it is not easily damaged under vehicle load and will not affect the road performance of the road surface.

[0031] In order for magnetic signal one and magnetic signal two to display the remaining distance of tidal channel 3 under the conditions of passability, non-communication and communication, there are 3 states. Since there are 2 magnetic poles, the number of magnetic fields needs to be at least 3.

[0032] To more clearly display the encoding methods 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 traffic status of tidal lane 3, and a second magnetic field group for displaying the remaining distance of tidal lane 3. Taking five magnetic fields as an example, the two magnetic fields at the ends of magnetic signal one and magnetic signal two, i.e., the first magnetic field group, can be encoded as NN, SS, and NS / SN. NN and SS can represent the traffic-accessible and traffic-inaccessible states of the tidal lane, respectively. When it is NS or SN, i.e., the two magnetic poles are different, it is a traffic-accessible state, and the encoding of the subsequent second magnetic field group is read. At this time, the encoding of the other three magnetic fields, i.e., the second magnetic field group, such as "NNN", "NNS", "NSN", "NSS", "SNN", "SNS", "SSN", and "SSS", can represent the remaining distance of 400m, 350m, 300m, 250m, 200m, 150m, 100m, and 50m from the end of the tidal lane, respectively.

[0033] Magnetic guidance module 1 41 and magnetic guidance module 2 42 need to be distributed along the tidal lane 3. Magnetic guidance module 1 41 and magnetic guidance module 2 42 are distributed at a certain distance along the direction of the tidal lane 3. Under normal circumstances, this distance is set to 50m. Depending on the vehicle speed, for some areas with slower vehicle speed, the distance can be shortened from 50m, and for some areas with faster vehicle speed, the distance can be increased from 50m.

[0034] Since the range of the magnetic field detected by the signal receiving module 43 is limited, in order to enable both the tidal lane 3 and the adjacent lanes to clearly detect magnetic signal one and magnetic signal two, magnetic induction module one 41 and magnetic induction module two 42 are located at the double yellow lines on both sides of the tidal lane 3, so that the distances from magnetic induction module one 41 and 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 magnetic signal one and magnetic signal two while the vehicle is in motion. The signal receiving module 43 is an on-board gaussmeter or Hall magnetic field detector installed in the vehicle.

[0036] Taking magnetic signal one and magnetic signal two, which are composed of magnetic pole codes corresponding to five magnetic fields, as an example, when the traffic flow in lane one 1 is large and needs to be diverted to tidal flow lane three, the DC coil 411 in magnetic induction module one 41 is connected to current. Through the current commutator 412, the direction of the DC coil current is changed, and its magnetic field signal is "NNNNN". Similarly, within 400m of the end of the tidal flow lane, magnetic induction module one 41 changes the direction of the DC coil 411 current through the current commutator 412, thereby changing the magnetic poles of the magnetic field and displaying the remaining distance of tidal flow lane three. The magnetic induction module 42 between lane 2 and tidal lane 3 is also connected to the current. Through the current commutator, the direction of the DC coil current is changed, and the magnetic field signal is "SSSSS". At this time, the signal receiving module 43 of the vehicle in lane 1 recognizes the passable signal of the auxiliary driving device and guides the vehicle to change lanes to tidal lane 3 and pass in tidal lane 3. At the same time, the vehicle in lane 2 recognizes the prohibition signal issued by tidal lane 3 received by the signal receiving module 43 and prevents the vehicle in lane 2 from changing lanes to enter the tidal lane.
