[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.
[0022] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Embodiment 1 like Figure 1-5 As shown, the present invention proposes an emergency vehicle priority passage system based on stroboscopic markings, including a map navigation module, which provides accurate road information, plans the optimal driving path for emergency vehicles, and marks the lanes that emergency vehicles can drive; an emergency vehicle terminal module, which serves as a bridge between the emergency vehicle and the cloud service platform and is responsible for data collection and command reception; an emergency vehicle drivable lane data module, which stores the drivable lane data of the emergency vehicle and provides a control basis for the stroboscopic marking control module; a lane stroboscopic marking control module, which controls the on and off of the stroboscopic markings according to the data provided by the emergency vehicle terminal module and the drivable lane data module of the emergency vehicle, and guides other vehicles to avoid; a lane marking terminal module, which receives commands from the cloud service platform and controls the on and off of the stroboscopic markings; and a vehicle networking cloud service platform, which integrates various modules of the system, performs data transmission and command issuance, realizes the function of emergency vehicle priority passage, and receives data sent by the lane marking module.
[0023] Furthermore, the lane marking includes a road body 1, a street lamp 5 arranged on the road body 1, and a stroboscopic stroboscopic luminous marking 3 arranged on the road body 1 and electrically connected to the street lamp 5; the road body 1 is a two-way four lanes or more, including a two-way emergency lane 2 and a normal lane.
[0024] First, if the road is a city surface road, When the road is a two-way four-lane road, the lane close to the middle will be used as emergency lane 2; When the road has six lanes or more in both directions, the second lane will be used as the emergency lane 2; If there is a bus lane in the traffic lane, the bus lane shall be used as the emergency lane 2.
[0025] Second, if the road is an urban expressway, When the road is a two-way four-lane road, the lane on the right side will be used as emergency lane 2; When the road has six lanes or more in both directions, the second lane will be used as the emergency lane 2; If there is a bus lane in the traffic lane, the bus lane shall be used as the emergency lane 2.
[0026] Third, if the road is a secondary road, and the general secondary road has two lanes, and one of them is a non-motorized vehicle lane, the second lane will be used as an emergency lane.
[0027] In this embodiment, in road condition one, since there are a large number of private vehicles on the urban ground roads, a large number of vehicles will temporarily park on the roadside. Therefore, the right lane cannot be used as an emergency lane at this time. At this time, the second lane is used as an emergency lane, which can effectively avoid the impact of parked vehicles on the passage of emergency vehicles.
[0028] In road condition 2, since expressways are generally three-lane or elevated, and the speed is relatively fast, there is no traffic light impact, and parking is not allowed on urban expressways and elevated roads, there is no need to worry about vehicles temporarily parking and occupying lanes, so the rightmost lane can be used as an emergency lane. Since general exits are on the right, emergency vehicles can easily enter and exit from the expressway. With the help of the expressway, traffic lights can be effectively avoided, which can effectively improve traffic efficiency.
[0029] In road condition three, since emergency vehicles are traveling on the auxiliary road, in order to avoid vehicles temporarily stopping on the roadside, the second lane is used as an emergency lane, which can effectively avoid being blocked by temporarily parked private vehicles. The private vehicles that are currently traveling enter the side road to give way.
[0030] According to the present invention, when an emergency occurs, such as a fire truck or an ambulance needs to pass, the emergency lane needs to be used. Through the emergency vehicle terminal module on the vehicle and the map navigation module, after the destination is input, the travel route can be calculated and planned, and the route plan to the destination can be planned in combination with the traffic flow data of the traffic command center. The lane data module for emergency vehicles provides a planning basis for the lane strobe module. When the emergency vehicle is driving, the lane strobe marking control module of the two hundred meters in the forward direction is controlled to light up, reminding the social vehicles in the lane so that they can leave the lane, which is convenient for the emergency vehicle to pass quickly. When the emergency vehicle arrives at the destination, the task route is closed and recorded as a task log. By analyzing the travel time and route planning, learning data is provided for subsequent faster travel, which is convenient for subsequent optimization of route planning.
[0031] Embodiment 2 like Figure 1-5 As shown, the present invention proposes an emergency vehicle priority passage system based on stroboscopic lane markings. Compared with the first embodiment, the lane stroboscopic lane marking control module in this embodiment includes a glass plate 31, a lamp fixing bracket 33 connected to the glass plate 31, and a stroboscopic lane marking 3 arranged under the glass plate 31; the stroboscopic lane marking 3 includes an LED lamp 32, a power supply circuit 34 electrically connected to the LED lamp 32 and a street lamp 5, a dimming driver 35 controlled by the LED lamp 32, a zero-ignition switch 36 electrically connected to the dimming driver 35, and a wireless sensor 37.
[0032] In this embodiment, the street lamp 5 supplies power to the LED lamp 32 through the power supply circuit 34. One street lamp 5 supplies power to 7 to 8 LED lamps 32 at the same time. The power supply method is parallel power supply, which can facilitate wiring. The zero-fire switch 36 is used to control the lighting of the LED lamp 32. The lamp fixing bracket 33 is used to fix the LED lamp 32, the zero-fire switch, the wireless sensor 37 and some connecting lines; the wireless sensor 37 adopts the NB-IoT wireless sensor, which has the characteristics of low frequency band, low power consumption, low cost, high coverage, high network capacity, suitable for long-distance transmission, and suitable for use in the present invention.
[0033] Embodiment 3 like Figure 1-5 As shown, the present invention proposes a method for giving priority to emergency vehicles based on stroboscopic road markings, the method comprising the following steps: S1. The map navigation module on the emergency vehicle plans the path information according to the origin and destination, and sends the path information to the Internet of Vehicles cloud service cloud platform through the emergency vehicle terminal module; S2. The cloud service platform of the Internet of Vehicles integrates the vehicle information and the path information, adds a road data of the emergency vehicle in the data module of the lane available for emergency vehicles, and marks the emergency vehicle on the lane through the map navigation module; S3, the Internet of Vehicles cloud service cloud platform integrates the information to locate the location of the emergency vehicle, and adjusts the lane strobe marking control module in the direction of the emergency vehicle in real time; S4: The lane strobe marking control module in the direction of vehicle travel performs continuous lighting operation to remind the vehicles in the lane; S5. When the vehicle passes by, the lane strobe marking control module at that location is in a closed state; S6. When the vehicle arrives at the destination, the emergency vehicle terminal module is turned off, and the Internet of Vehicles cloud service platform determines that the service has ended and keeps a record.
[0034] The Internet of Vehicles cloud service platform detects the road conditions in the direction of the emergency vehicle through the map navigation module at intervals of t. If there is a lot of congestion in the direction of travel, the route will be replanned.
[0035] In this embodiment, the vehicle network cloud service platform detects the road conditions in the direction of emergency vehicles through the map navigation module at regular intervals to detect whether there is congestion in the direction ahead, and provides feedback based on the detection results. If there is no congestion, the vehicle moves forward normally. If there is slight congestion, the lane strobe marking control module controls the lighting to enable private vehicles in the emergency lane to leave the lane and drive to the surrounding lanes while ensuring safety, thus freeing up the lane so that the emergency vehicle can pass quickly. This module can quickly clear the emergency lane so that the emergency vehicle can pass quickly. If there is a traffic accident, maintenance, etc. on the road in the direction of travel that cannot be cleared quickly and there is a lot of congestion, it is necessary to re-plan a new route so that the emergency vehicle can travel via other routes and avoid congested sections so that the emergency vehicle can pass quickly.
[0036] When the emergency vehicle passes, the lane strobe marking control module is in a closed state, allowing vehicles behind the emergency vehicle to enter the emergency lane, thereby speeding up the relief of congestion caused by avoiding the emergency vehicle and improving overall traffic efficiency.
[0037] After the vehicle arrives at the destination, the emergency vehicle terminal module is turned off, the vehicle network cloud service platform records the route of the trip and generates a path driving log. By analyzing the driving log, the planned path can be optimized and the road conditions can be adjusted to achieve higher traffic efficiency.
[0038] Embodiment 4 like Figure 1-5 As shown, the present invention proposes a method for giving priority to emergency vehicles based on stroboscopic markings. Compared with the third embodiment, the present embodiment further includes a coordination module, which is connected to a traffic command center. When there is a large amount of congestion on the route of the emergency vehicle, it is also connected to the traffic command center through the coordination module. The traffic command center assigns the task to nearby motorcycles to clear the way in the direction of the vehicle. The coordination module can upload the vehicle position information and route information to the traffic command center in real time. The traffic command center assigns the task information to nearby motorcycles or patrol officers according to the location of the emergency vehicle. After receiving the information, the motorcycles or patrol officers converge or arrive in front of the direction of travel according to the location of the emergency vehicle and their own location information, clear the social vehicles on the road, and determine whether there are social vehicles temporarily parked on the roadside. When there are temporarily parked social vehicles on the lane where the emergency vehicle passes, if there is a driver on the social vehicle, let the driver drive out of the lane. If there is no driver on the social vehicle, notify the driver to move the car, or the motorcycles perform temporary traffic control here, so that the emergency vehicle can travel in the lane next to it to ensure the traffic efficiency of the emergency vehicle. The lane strobe marking control module controls the strobe marking 3 within 200 meters of the vehicle's forward direction to work according to the vehicle positioning information, and performs continuous lighting operation.
[0039] The lane strobe marking control module is automatically controlled. The control mode is a single strobe marking module, not a group. Each control range is 200 meters. Emergency vehicles can make real-time judgments while traveling. Determine whether there is an intersection within 200 meters ahead of the current path. If there is no intersection, the lane markings of the first 200 meters of the road section will be turned on. If there is an intersection, the distance x from the emergency vehicle to the intersection and the strobe marking module within the range of (200-x) after exiting the intersection will be turned on. The lane strobe marking control module can be used to control the lane information at the intersection in advance. By controlling the lane strobe marking control module and traffic lights at the intersection, private vehicles at the intersection can be informed that an emergency vehicle will soon pass through the intersection and they need to perform avoidance operations, allowing the emergency vehicle to pass faster.
[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
