The highway is an important channel of transportation, plays an important role in daily life, and has a great influence on the traffic of the highway in severe weather, for example, a great proportion of serious traffic accidents occur in three weather conditions of heavy fog, rain and snow and icy road every year.
Weather information is usually obtained through a weather monitoring system and is sent to an upper computer. The upper computer analyzes the meteorological information, generates weather early warning information, and displays the weather early warning information through a display device arranged on the side of the expressway, so that a driver is prompted.
However, in severe weather conditions, such as heavy fog weather or heavy rain and snow weather, the driver may not see the display device clearly, and the warning information may be transmitted less effectively. How to improve under the bad weather condition, the transmission effect of meteorological early warning reduces the emergence of traffic accident is the problem that needs to solve at present urgently.
In view of this, the embodiment of the present application provides a highway weather warning system 1 and a method, in which the roadside system 10 directly communicates with a vehicle to send warning information to the vehicle, so as to improve the effect of transmitting the warning information, thereby reducing the occurrence of accidents. The above scheme is explained in detail below.
Referring to fig. 1, fig. 1 is a block diagram illustrating a weather warning system 1 for a highway according to an embodiment of the present disclosure. As shown in fig. 1, the highway weather early warning system 1 includes a roadside system 10 and an early warning cloud platform 20, which are in communication connection with a weather monitoring system, wherein the roadside system 10 is in communication connection with the early warning cloud platform 20, and is in communication connection with all vehicles within a preset communication range.
The early warning cloud platform 20 is configured to receive the meteorological data of the preset area sent by the meteorological monitoring system, analyze the meteorological data to obtain weather condition data of each road section of the highway in a preset time period, and send the weather condition data to the roadside system 10.
And the roadside system 10 is used for generating early warning information according to the weather condition data and then sending the early warning information to all vehicles within a preset communication range so as to remind drivers of the vehicles of paying attention to driving safety.
The roadside system 10 includes a Road Side Unit (RSU) and an edge computing device, where the edge computing device is in communication connection with the Road Side Unit, and can directly receive data through the Road Side Unit and process the data.
For example, the edge computing device may receive, through the roadside device, the weather data of the preset area sent by the weather monitoring system, analyze the weather data to obtain weather condition data of each section of the expressway at a preset time period, and send the weather condition data to the roadside device.
The roadside system 10 communicates with vehicles within a communication range thereof through a Vehicle-mounted wireless communication V2X (V2X) protocol, and the Vehicle-to-Vehicle, the Vehicle-to-roadside device, and the roadside device can communicate with each other by using the protocol. Therefore, a series of traffic information such as real-time road conditions, road information, pedestrian information and the like is obtained, so that the driving safety is improved, the congestion is reduced, and the traffic efficiency is improved.
Meanwhile, the roadside system 10 may be plural, and a plurality of roadside systems 10 are arranged along the highway. By using the protocol, the vehicle can communicate with the road side system 10, and the vehicle can quickly obtain the information sent by the road side system 10, so that the information transmission efficiency is improved.
Further, the roadside system 10 and the early warning cloud platform communicate through a 4G/5G communication technology.
The meteorological data may be from meteorological monitoring equipment installed along a highway in a meteorological monitoring system, or from meteorological observation satellites in a meteorological monitoring system.
Further, the meteorological data may include air temperature, precipitation, surface temperature, humidity, wind direction, wind speed, visibility, and the like in a preset area.
The early warning cloud platform 20 may analyze the meteorological data based on a preset threshold value to obtain weather condition data of each section of the highway in a preset time period. For example, precipitation is small rain at a rain of not more than 10 mm, precipitation is small to medium rain at 5 mm to 16.9 mm, medium rain is 10 mm to 24.9 mm, medium to large rain is 17 mm to 37.9 mm, large rain is 25 mm to 49.9 mm, large to large rain is 38 mm to 74.9 mm, more than 50 mm is called heavy rain, more than 100 mm is called heavy rain, and more than 250 mm is called extra heavy rain.
As another example, visibility is greater than 1000LJ(m) is fog-free weather, and the visibility is 500-1000LJ(m) is the fog weather, and the visibility is 200-500LJ(m) is in light fog weather, and the visibility is 100-200LJ(m) is in medium fog weather, and the visibility is 50-100LJ(m) is in heavy fog weather, and the visibility is less than 50LJ(m) is dense fog weather.
The above-mentioned early warning information may include: "fog ahead, please drive carefully", "rainstorm ahead, please drive carefully", "crosswind ahead, please drive carefully", "icy road ahead, please drive carefully", etc.
For example, when the early warning cloud platform 20 determines that the weather condition is a heavy rain, the roadside system 10 generates early warning information of "heavy rain ahead, please drive carefully" according to the weather condition data.
As a possible implementation scenario, if a certain vehicle runs in the high-speed beijing segment of jinghu (the high-speed beijing segment of jinghu includes beijing segment, tianjin segment, northriver segment, Shandong segment, Jiangsu segment, and Shanghai segment). The early warning cloud platform 20 receives the weather data in the area to which the road segment belongs, and analyzes the weather data to obtain the weather condition data of the road segment in the preset time period. For example, the precipitation amount of 60 mm in the beijing section from 12 pm to 13 pm on 6/9/2020 can be determined according to the precipitation amount, and the rainstorm can be determined in the beijing section from 12 pm to 13 pm on 6/9/2020.
At this time, the early warning cloud platform 20 may send weather condition data to the roadside system 10 located in the beijing segment, and after receiving the weather condition data, the roadside system 10 generates corresponding early warning information and sends the early warning information to the vehicle, so that a driver of the vehicle can know the early warning information.
The embodiment of the application provides a highway meteorological early warning system 1, and this system includes roadside system 10 and early warning cloud platform 20 with meteorological monitoring system communication connection, and roadside system 10 and early warning cloud platform 20 communication connection, and with the equal communication connection of all vehicles of predetermineeing the communication range. Weather data analysis that the meteorological monitoring system who obtains through early warning cloud platform 20 sent obtains weather condition data in the preset area to with weather condition data transmission to roadside system 10, roadside system 10 generates early warning information according to weather condition data, and with early warning information transmission to the vehicle in the communication range, through the mode of direct with early warning information transmission to vehicle, avoided under the severe weather early warning information transmission not in place problem, and then improved the security of driving on the highway under the severe weather.
Referring to fig. 2, fig. 2 is a second schematic block diagram of a highway weather warning system 1 according to an embodiment of the present disclosure. In order to make the early warning information more intuitive and efficient, the highway weather early warning system 1 may further include a plurality of variable signal devices 30, the plurality of variable signal devices 30 being arranged along the highway, and each variable signal device 30 being in communication connection with the roadside system 10.
The roadside system 10 is further configured to send the warning information to each variable signal device 30 for display.
The variable signal device 30 is any one of an LED display screen (LED display) and an LCD display screen (Liquid crystal display).
Therefore, the variable signal device 30 arranged along the highway displays the early warning information, so that the transmission effect of the early warning information can be further improved, and a driver can obtain the early warning information more intuitively.
Under some extremely severe weather conditions, the effect of avoiding the occurrence of traffic accidents is limited by only sending early warning information to the vehicles, and therefore, in order to further improve the driving safety of the highway, the embodiment of the application can further perform driving management and control on the vehicles running on the highway.
As another embodiment, the vehicle is equipped with an on-board terminal that is communicatively connected to the roadside system 10.
The roadside system 10 is further configured to receive position information and driving state information of a vehicle, which are acquired by a vehicle-mounted terminal within a preset communication range, generate regional traffic state information according to the position information and the driving state information, and send the regional traffic state information to the early warning cloud platform 20.
The early warning cloud platform 20 is further configured to analyze the regional traffic state information and the meteorological data to obtain regional control information, and send the regional control information to the roadside system 10.
The roadside system 10 is further configured to receive the region management and control information, and send the region management and control information to all vehicle-mounted terminals within the preset communication range, so that all vehicles within the preset communication range run according to the region management and control information.
The area control information may be information for prompting that the vehicle is driven away from the high speed, information for prompting speed limit, or information for prompting that the vehicle is retained in a service area.
The position information of the vehicle comprises the longitude and latitude of the vehicle and the lane information of the vehicle. The running state information of the vehicle includes a speed of the vehicle, an acceleration of the vehicle, and a direction angle of the vehicle.
The roadside system 10 analyzes and obtains regional traffic state information of the region located in the communication range according to the position information and the driving state information collected by at least one vehicle in the communication range. For example, the number of vehicles in the area is large, and the vehicle speeds are all smaller than the preset value and even 0, which indicates that traffic jam conditions may occur in the area.
Further, the early warning cloud platform 20 analyzes the area management and control information according to the area traffic state information and the meteorological data. For example, if the weather data indicates that the weather is fog weather at present and there are many vehicles in the communication range, the region control information of "fog in front, please drive carefully, and the speed limit is 80 Km/h" is issued.
The specific numerical value of the speed limit can be determined by combining with the actual situation and is determined according to the traffic volume of the vehicle in the current communication range, the positions of different road sections and the weather condition information.
For another example, when the early warning cloud platform 20 obtains the weather condition of the extra-heavy rainstorm according to the weather data analysis, the area management and control information of "extra-heavy rainstorm weather please stay in the service area" is generated according to the weather condition, so that the vehicle driving on the target road section stays in the service area, so as to ensure the traffic safety.
The specific information for inducing the vehicle to run can also be determined by combining with the actual situation, and is determined according to the traffic volume of the vehicle in the current communication range, the positions of different road sections and the weather condition information.
Further, each variable signaling device 30 may also be communicatively connected to the early warning cloud platform 20. The early warning cloud platform 20 is further configured to send the area management and control information to the variable signal device 30 for display.
Thus, the area control information is displayed through the variable signal devices 30 arranged along the highway, so that the transmission effect of the area control information can be further improved, and a driver can obtain the area control information more intuitively.
