This embodiment provides a method for quickly identifying the location of an expressway accident scene, including the following steps:

S101. Obtain the license plate information of the accident vehicle, and obtain the record of the accident vehicle in the expressway toll stream according to the license plate information.

Connect to the emergency call at the scene of the accident, use the expressway toll flow query module to query the toll flow of the expressway according to the license plate number provided by the driver, and arrange according to the time sequence from near to far to determine the record of the last time the vehicle at the accident scene appeared in the toll flow.

The expressway toll flow query module can be connected with the current expressway toll flow database, directly use the existing database to query the latest toll records of vehicles, and can also add a simple license plate flow database in the process of expressway toll flow processing. Reduce the amount of data in the database and increase the query speed of data, at least including license plate information, toll time, toll station or door frame name. Because these databases are public, it is convenient to build modules and is universal.

S102. According to the license plate information, query the vehicle location record sent by the vehicle-mounted satellite of the two passengers and one dangerous vehicle, and obtain the location information of the accident vehicle; judge whether the accident scene is located at the intersection of the expressway according to the location information, and if so, according to the obtained record in the toll flow of the expressway Determine the highway section where the accident vehicle is located; otherwise, directly determine the highway section where the vehicle is located.

According to the driver's license plate number, use the accident scene positioning module to query the vehicle location record sent by the "two passengers and one danger" vehicle satellite, and determine the approximate latitude and longitude point position of the vehicle. If the accident scene is located at the intersection of the expressway, use the expressway toll The flow query information determines the highway section where the vehicle is located. If it is located at a non-interchange, the highway section where the vehicle is located can be directly determined.

S103. Obtain the guardrail color of the expressway at the accident scene, and determine whether the accident scene is on the uplink or downlink of the expressway according to the guardrail color, so as to obtain the specific location of the accident vehicle; wherein, the guardrail color on the uplink is the same as the guardrail color on the downlink. different.

According to the color of the expressway guardrail described by the driver, compare the color and direction against the database to judge the direction of the accident scene on the expressway (up and down), so as to determine the specific position of the vehicle. As an optional implementation, the color and direction comparison database includes five fields: serial number, road section name, road section code, color setting, and road direction.

As an optional implementation manner, step S102 may be replaced by the following step: acquiring the location information of the vehicle in the accident through a wireless communication network.

As another optional implementation, in step S102, according to the license plate information, query the vehicle location record sent by the vehicle satellite of the two passengers and one dangerous vehicle, and/or obtain the location information of the accident vehicle through the wireless communication network.

According to the license plate information, the existing database can be directly used to obtain the approximate location information of the accident vehicle, without adding additional new traffic facilities, the approximate area of the accident scene can be determined at the first time, and personnel can be quickly dispatched. The accident scene positioning module is combined with the existing "two passengers and one danger" vehicle latitude and longitude database, which can determine the approximate location of the accident scene without requiring additional economic expenditure and accurate description of the scene. At the same time, it is considered that if a small family vehicle is not equipped with on-board satellite positioning, specific point information can be obtained through mobile phone signaling data, even though the latter takes longer than the former. Because the existing "two passengers and one dangerous" vehicle latitude and longitude database is an open database, it is more convenient to use, but through the wireless communication network, the authorization of the operator is required.

As an optional embodiment, referring to Fig. 2, the coloring method of the colored guardrail includes using specific colors, such as black for uplink, white for downlink, red for uplink, green for downlink, etc.; or specific color combinations, such as a single Color indicates uplink, double color indicates downlink, etc.; or a specific color pattern, such as black and yellow for uplink, black and red for downlink, etc.

The above method will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the present embodiment provides a method for quickly identifying the location of an expressway accident scene, including the following steps:

S1. Develop a database for expressway color and direction comparison, connect the accident handling unit with the expressway flow database, the latitude and longitude location database of "two passengers and one dangerous" vehicles, and the mobile phone signaling location database, so as to ensure that no mobile phone information is used during information processing. side is hindered.

Step S1 includes the following contents S11-S12:

S11. Expressway color and direction comparison database needs to first paint the color of the expressway guardrail, as shown in Figure 3, and then map the direction information of the road section to the color, as shown in Table 1, and store the results locally.

Table 1

S12. Request the expressway flow database, the "two passengers and one dangerous" vehicle latitude and longitude location database and/or mobile phone signaling location database and access rights, such as database connection address, user name and password, and integrate the database information into a unified B/S In the (Browser browser/Server background server) structure, users can directly access three kinds of databases through the browser, as shown in FIG. 4 .

S2. When a traffic accident occurs on an expressway section, the accident emergency response unit receives a call for help at the scene of the accident, and uses the expressway toll flow query module to determine the section of the accident scene according to the license plate information; The positioning module determines the approximate location of the accident scene; according to the color information of the highway guardrail and the database of highway color and direction comparison, the up and down direction of the highway where the accident scene is located is determined, so as to obtain the detailed location information of the accident scene.

Step S2 includes the following contents S21-S22:

S21. When using the expressway toll flow query module, the user only needs to input the license plate information and mobile phone number information at the front end, click the query button and wait for the result to be returned from the background, as shown in Figure 5.

S22. The background should set a fixed query template to obtain the latest data of the accident vehicle, for example:

Determine the specific road section: "select vehicle_plate,time,instation_id,road_code fromhighwayTable20221024where vehicle_plate='xxxxxxx' order by time desc limit 1" means to query the license plate from the expressway toll flow database on October 24, 2022 in order from near to far It is the vehicle_plate (license plate), time (time), instation_id (the toll station or gantry id of the accident vehicle entering the expressway) and road_code (the entry number of the expressway section) field information of the latest xxxxxxx, so as to obtain the accident vehicle entering the expressway tollbooth or the last gantry passing by.

Determine the location point of the accident vehicle: "select vehicle_plate,lng,lat,time fromGPS20221024where vehicle_plate='xxxxxxx' order by time desc limit 1" means from the "two passengers and one danger" vehicle latitude and longitude position database on October 24, 2022 according to the Query the vehicle_plate (license plate), lng (longitude), lat (latitude), and time (time) field information of the latest vehicle_plate (license plate), lng (longitude), lat (latitude), time (time) field information of the license plate xxxxxxx in order from near to far, so as to obtain the latest satellite positioning information of the accident vehicle.

Determine the location of the emergency call: "select phone_number,lng,lat,time from phone_message_20221024where number='xxxxxxxxxxx' order by time desc limit 1" indicates that the latitude and longitude position database of "two passengers and one danger" vehicles on October 24, 2022 according to Query the latest phone_number (mobile phone number), lng (longitude), lat (latitude), and time (time) field information of the latest phone number xxxxxxxxxxx in order from near to far, so as to obtain the latest location information of the emergency call at the accident scene.

S23. After obtaining the road section information, it is necessary to input the road section information and guardrail color to query the flow direction, as shown in FIG. 6 . Determine the specific direction of the road section at the accident scene: "select road_name,road_code,guardrail_color,direction from color_road_table where guardrail_color='colorless' and road_code='xxxxxxxxxxx'" indicates that the road_name of the highway section whose color is colorless and whose road section code is xxxxxxxxxxx (road section name), road_code (road section code), guardrail_color (guardrail color), direction (road section direction) field information, determine the direction of the road section where the accident vehicle is located.

S24. The front end should have the function of displaying graphic information and detailed text information of the positioning location according to the latitude and longitude. After the system user inputs the license plate information and emergency number information, the returned results are visualized on the webpage, as shown in Figure 7.

To sum up, compared with the prior art, the method of this embodiment has at least the following advantages and beneficial effects:

(1) This example fully exploits the value of data, uses the expressway toll flow data and the location data of "two passengers and one danger" to serve the expressway accident scene, and improves the accuracy of expressway accident scene positioning.

(2) This example uses the B/S structure to query the location of the accident scene, which is convenient and quick to operate, and narrows the scope from large to small, from surface to point, and quickly determines the location information of the expressway accident scene, as shown in Figure 8.

(3) This embodiment judges the trend of the highway accident scene by using the color of the expressway guardrail covering the whole process, without the need for the driver to look for the sign board to judge the direction of the road where he is currently, saving rescue time, especially in the case of the driver's inconvenient movement The effect is more pronounced.

(4) The scheme in this embodiment only needs to use paint to paint the color of the expressway guardrail, does not need to increase or modify other facilities of the expressway, does not need simulation, and can be achieved without changing the safety conditions of the expressway. The function of transmitting information is economical and practical.

The present embodiment also provides a system for quickly identifying the location of an expressway accident scene, including:

The expressway toll flow query module is used to obtain the record of the accident vehicle in the expressway toll flow according to the obtained license plate information;

The accident scene positioning module is used to query the vehicle location records sent by the two passengers and one dangerous car satellite according to the license plate information, and obtain the location information of the accident vehicle; judge whether the accident scene is located at the highway interchange according to the location information, and if so, according to the obtained highway The records in the toll flow water determine the expressway section where the accident vehicle is located; otherwise, directly determine the expressway section where the vehicle is located;

The color and direction comparison database is used to determine whether the accident scene is on the uplink or downlink of the expressway according to the obtained guardrail color of the expressway at the accident scene, so as to obtain the specific position of the accident vehicle; wherein, the color of the guardrail on the uplink is the same as The guardrails on the downwalk are a different color.

As an optional implementation, the expressway toll flow query module can be connected with the current expressway toll flow database, and directly use the existing database to query the latest toll records of vehicles, or it can be added in the process of expressway toll flow processing. Add a simple license plate flow database to reduce the amount of data in the database and improve the query speed of data, at least including license plate information, toll time, toll station or door frame name.

As an optional implementation, the accident scene positioning module can perform vehicle positioning or mobile phone positioning. Vehicle positioning mainly uses the "two passengers and one dangerous" vehicle-mounted Beidou satellite position transmitter, which transmits latitude and longitude position information every 10 to 30 seconds. Mobile terminal signal location positioning can also be used.

As an optional implementation, the color and direction comparison database includes five fields: serial number, road section name, road section code, color setting, and road direction. Coloring guardrails includes the use of specific colors, such as black for up, white for down, red for up, green for down, etc.; or specific color combinations, such as a single color for up, double colors for down, etc.; or specific color patterns, For example, black and yellow alternately indicate uplink, black and red alternately indicate downlink, etc.

As can be seen from the above, the expressway toll flow query module of the present embodiment can directly use the existing database to obtain the approximate location information of the accident vehicle, without adding additional new traffic facilities, and can determine the approximate interval of the accident scene at the first time. Quickly dispatch personnel; the accident scene positioning module is combined with the existing "two passengers and one dangerous" vehicle latitude and longitude database, which does not require additional economic expenditure and can determine the approximate location of the accident scene without an accurate description of the scene At the same time, if it is a small household vehicle without on-board satellite positioning, the specific point information can be obtained through mobile phone signaling data, even though the latter takes longer than the former, but in the expressway toll flow query module Under the premise of assistance, a two-pronged approach can be achieved. Since the positioning accuracy of civil Beidou satellites is about ten meters, and there is an intersection of expressways, there may be deviations between adjacent roads directly through Beidou satellite positioning. Therefore, the expressway toll flow query module is also necessary. Indispensable; the color and direction comparison database only needs two kinds of content corresponding to the colored guardrails, which are used to mark the up and down lines; the color, color combination, and color pattern of the colored guardrails can be set arbitrarily, as long as the reference color and direction comparison database At the same time, it does not need to completely cover the guardrail, so it does not conflict with the color setting required by the traffic safety field.
