As shown in fig. 1:
step 1000: acquiring current traffic accident location information of a traffic accident occurrence location; the car accident location information includes car accident location information and vehicle specific location information.
In the process of acquiring the current traffic accident site information, various modes can be adopted; firstly, the corresponding car accident positioning information can be formed by grafting the car accident data in the Baidu map, namely directly calling the car accident points formed in the Baidu map; secondly, the vehicle positioning information can be identified through a camera preset on a road, the method can be used for the high-altitude road, and the conditions such as stopping on the expressway are not allowed, so that the vehicle positioning information can be identified based on the conditions, namely the condition that the vehicle in the corresponding area is shot through the camera, the vehicle in the current area is identified, if the vehicle in the shot area does not move all the time, the accident can be preliminarily determined, the information can be timely fed back to a worker for processing, and the worker further confirms whether the accident occurs at the corresponding position, so that the vehicle positioning information is formed; thirdly, the traffic accident location information can be obtained based on the intelligent isolation guardrail, and the traffic accident location information is preferably obtained through the intelligent isolation guardrail in the embodiment as follows:
as shown in fig. 2, a method for acquiring current car accident location information may be as follows:
step 1100: acquiring current trigger identification information; the trigger identification information includes button trigger information and image information.
Regarding the acquisition of button activation information: the corresponding traffic accident triggering button can be preset on each intelligent isolation guardrail, the intelligent isolation guardrails are in wireless and/or wired data communication connection with the server, and when people press the traffic accident triggering button, the button triggering information is obtained.
Regarding the acquisition of image information: there are two ways to obtain image information: firstly, a camera preset on a highway can be used for shooting and acquiring a corresponding picture, namely the camera arranged above is used for shooting a specific picture to form image information; secondly, a camera preset on the intelligent isolation guardrail can be adopted to obtain image information; in the two acquisition modes, different modes are required to be adopted for identification due to different installation positions of the cameras.
Step 1210: and searching current preset position information corresponding to the current button trigger information from the corresponding relation between the preset button trigger information and the preset position information.
Step 1220: and forming current car accident positioning information according to the current preset position information.
After the current button trigger information is acquired, inquiring between preset button trigger information and preset position information, and inquiring the preset position information corresponding to the current button trigger information. And determining current car accident positioning information according to the preset position information. The triggering process is realized according to the manual starting button, so that the position of the car accident is positioned, namely the button corresponds to the preset position, the association is realized, and once the corresponding button is triggered to acquire the related button triggering information, the preset position information corresponding to the button triggering information can be called, so that the car accident positioning information is formed.
Step 1310: and analyzing and forming the current vehicle specific position information according to the image information.
Wherein, the method for forming the specific position information of the current vehicle comprises the following steps:
step 1311: acquiring image information of a position corresponding to the current traffic accident positioning information; the image information includes vehicle image information and lane image information.
The vehicle image information and the lane image information are acquired by an image recognition method, namely, the characteristic points of the vehicle or the lane are recognized according to a characteristic point recognition method in the image recognition, and then the vehicle image information and the lane image information are determined and formed.
Step 1312: and determining the specific position information of the current vehicle where the current vehicle is located according to the lane image information and the vehicle image information.
Step 1313: and marking the lane lines in the lane image information along a preset reference direction in sequence to form lane line marking information.
The preset reference direction may be from left to right, or from right to left; in this embodiment, lanes are marked in sequence according to a left-to-right direction, for example: a first lane line, a second lane line, a third lane line, a fourth lane line, a fifth lane line, and the like; a first lane is formed between the first lane line and the second lane line, a second lane is formed between the second lane line and the third lane line, a third lane is formed between the third lane line and the fourth lane line, a fourth lane is formed between the fourth lane line and the fifth lane line, and the like.
Step 1314: and recognizing the position relation between the lane line corresponding to the lane image information and the vehicle corresponding to the vehicle image information, and determining the specific position information of the current vehicle according to the lane line mark information.
If a camera preset on the highway is adopted to shoot and obtain image information; the vehicle is arranged on the upper side, so that the relationship between the vehicle and the lane is very detailed, and the situation that the lane is positioned in which the vehicle body cannot be confirmed because the vehicle body of the vehicle covers most lane lines is avoided; the specific identification is as follows: judging whether a lane line in the lane image information is overlapped with a vehicle in the vehicle image information or not according to the image recognition, if so, indicating that the vehicle is overlapped with the lane line, namely the vehicle possibly spans at least two lanes; after the overlapping is determined, judging that the overlapped lane line is the marked second lane line, and if the overlapped lane line is the third lane line; and further judging whether two adjacent lane lines overlap with the vehicle, if not, indicating that the vehicle is in the second lane and the third lane, and if so, further judging whether two lane lines extending outwards from the overlapped lane lines overlap with each other until judging that the two lane lines do not overlap with each other.
If a camera preset on the intelligent isolation guardrail is adopted to obtain image information; because intelligence isolation barrier is located the side, the visual angle of event shooting is from the side shooting, so in shooting process, the easy appearance is because the sheltering from of vehicle and the lane line that leads to shooting is sheltered from the condition, so need adopt different recognition mode, specifically as follows: according to the image recognition, the lane lines in the lane image information are recognized, whether the lane lines in the lane image information are overlapped with the vehicles in the vehicle image information or not is judged, and according to the overlapping condition, the fact that the corresponding number of the lane lines are not overlapped with the vehicles is judged; if two lane lines do not overlap with the vehicle, the vehicle is in the second lane, and if one lane line does not overlap with the vehicle, the vehicle is in the first lane, and so on.
Because need enclose through intelligent isolation barrier and close and form the isolation region, so need confirm the concrete position that takes place the car accident, through carrying out the analysis to data information in the image in order to form the concrete position information of current vehicle, be convenient for realize intelligent isolation barrier's the call removal.
And when the current car accident site information is acquired, lane change reminding information is formed to remind the vehicles in the preset detection area. The lane change reminding information can be voice reminding information or light reminding information, and can be realized by presetting a horn and an indicator light on the intelligent isolation guardrail; the rear vehicles can be guaranteed to smoothly avoid the area of the front traffic accident and effectively avoid the intelligent isolation guardrail in the moving state, and then the rear coming vehicles are reminded.
Step 2000: searching current guardrail calling information corresponding to the current traffic accident positioning information from a preset corresponding relation between the traffic accident positioning information and the guardrail calling information; and calling the intelligent isolation guardrails corresponding to the guardrail calling information according to the traffic accident positioning information.

The mode of obtaining vehicle detection image information can be identified by a camera arranged on the intelligent isolation guardrail, and each intelligent isolation guardrail corresponds to one position.
Step 3200: and judging whether the vehicle exists according to the vehicle detection image information.
The vehicle detection image information is used for judging whether a vehicle exists or not by adopting an image identification mode, namely, whether the vehicle exists in the current image or not is identified.
Step 3300: and if the vehicle does not exist in the vehicle detection image information, moving the current intelligent isolation guardrail until an isolation area is formed by enclosing.
Wherein, if do not have under the condition of vehicle, the removal just can take place for intelligent isolation barrier to enclose synthetic isolation region, the effectual rear vehicle of avoiding drives and does not pay attention to and the condition of taking place the car accident. Lanes on the defined roadway include lateral lanes and a middle lane.
Step 3310: and judging the lane where the current vehicle is located according to the specific position information of the vehicle.
Step 3321: if the vehicle is located in the side lane, the intelligent isolation guardrails corresponding to the side lane are controlled to be started to enclose to form an isolation area.
Step 3322: if the vehicle is located in the middle lane, the intelligent isolation guardrails on the two sides are controlled to be started to enclose to form an isolation area.
In order to improve the efficiency of enclosing, generally adopt principle nearby to enclose and close, if promptly in the side lane, then directly enclose through the intelligent isolation barrier who is close to the side and close, if in the middle part lane, then directly the intelligent isolation barrier common boot through both sides encloses and closes, all protects both sides in order to play more protection effect, all reduces the possibility that takes place the secondary car accident with both sides.
According to the intelligent isolation guardrail corresponding to the current guardrail calling information, the first intelligent isolation guardrail and the last intelligent isolation guardrail which are sequentially arranged according to the vehicle running direction are determined, the first intelligent isolation guardrail is defined as a head intelligent isolation guardrail, the last intelligent isolation guardrail is defined as a tail intelligent isolation guardrail, and the intelligent isolation guardrail between the head intelligent isolation guardrail and the tail intelligent isolation guardrail is a middle intelligent isolation guardrail.
