Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, the embodiment of the invention provides an intelligent expressway traffic accident alarming method based on a virtual fence, which comprises the following steps:
s101: drawing a virtual fence of a polygonal area and initializing stake number information by using an application interface provided by map navigation software, wherein the stake number information comprises: pile number, corresponding travelling direction, belonging level and judging distance;
as an embodiment, the step comprises the sub-steps of:
s1011: as shown in fig. 2, the expressway is divided into an uplink area and a downlink area by using the function of drawing a polygonal area provided by map navigation software, and virtual fences are respectively drawn and stored in a database;
specifically, the map navigation software may be a hundred degree map, a high-german map, a Tencel map, or the like. As shown in fig. 2, the uplink region virtual fence is further divided into three parts: highway region, highway-out region and isolation zone region; similarly, the downlink region virtual fence is also specifically divided into the three parts. In practical application, the range beyond the highway area can be set to be 100-200 meters, and the specific value is determined according to the practical situation.
S1012: the actual stake marks on the expressway are used as contrast, stake marks are marked on corresponding positions in the drawn virtual fence by utilizing the function of mouse ranging provided by map navigation software, and the stake marks are stored in a database;
s1013: initializing pile number information and storing the pile number information into a database.
Specifically, the types of stake marks are classified into three types, namely accident-prone stake marks, bend positions and normal road stake marks. The three types of pile numbers are respectively numbered, the traveling direction (uplink and downlink), the belonging level and the judgment distance are set.
For example, the accident-prone spot number may be Si, the rank is 1, and the determination distance is set according to the actual situation of the accident-prone spot; wherein i is required to meet the normal mileage, for example, i= 220,335;
the number of the stake marks at the curve can be Ui, the belonging level is 2, and the judging distance is judged according to the actual condition at the curve; wherein i is set according to actual requirements.
The number of the normal road stake number may be consistent with the actual mileage stake number of the highway, such as Ki (i= 0,100,200,300, …), with a grade of 3, and a determination distance of 50 meters.
As shown in fig. 3, two pile number types, ki and Si, respectively, are provided in the figure.
It should be noted that, by setting the grade to which the pile number belongs, the subsequent judging time of the pile number can be shortened; for example, the accident-prone pile number is most likely to occur, so that when the pile number of the accident report point is determined, screening can be performed preferentially from all accident-prone pile numbers.
S102: acquiring accident information by using a WeChat applet terminal, wherein the accident information comprises accident reporting point coordinates;
specifically, a user opens a WeChat applet end capable of carrying out accident reporting, automatically jumps to an accident reporting page, automatically invokes associated map navigation software to automatically acquire accident reporting point coordinates, and carries out accident information reporting.
As an embodiment, the accident information further includes: rescue information and contact person information; the rescue information is filled manually by a user; the contact information is automatically filled pre-initialized contact information.
Specifically, the user can manually fill in relevant rescue information at the corresponding position of the accident report page, including the number of wounded persons, the number of accident vehicles, the accident photos and other supplementary information;
in addition, in order to reduce the user operation time, the user may pre-initialize the contact information and then enable the system to automatically populate the contact information, including contact names, phones, warning license plates, etc., by setting permissions.
S103: calculating according to the accident reporting point coordinates to obtain a traveling direction and a belonging pile number;
as an embodiment, the step comprises the sub-steps of:
s1031: the accident report point coordinates are corresponding to the virtual fence, and then a horizontal and vertical intersection point number judgment method is adopted to judge to obtain the advancing direction;
for example, as shown in fig. 4, three points A, B, C in the diagram are set as accident reporting points, and the determination in the uplink and downlink directions is performed by using the defined virtual fence, and the following determination is made in combination with the reporting points in the diagram:
case a: and judging that the direction belongs to the uplink, and automatically modifying the direction into the uplink and storing the uplink into a database.
Case C: and judging that the direction belongs to the downlink, and automatically modifying the direction into the downlink and storing the downlink into a database.
Case B: in this case, the direction determination is not performed, the rescue organization communicates with the person seeking help, and if the communication is impossible, the person is dispatched from the nearest rescue station to rescue.
S1032: and determining all pile numbers in the travelling direction, calculating the distance between the accident reporting point coordinates and each pile number, and taking the pile number corresponding to the minimum distance value as the belonging pile number.
Specifically, the method adopts a grading mode to determine the belonging pile number, and specifically comprises the following substeps:
step A1: determining all accident multiple-place pile numbers with the level of 1 in the travelling direction, sequentially calculating the distance between the accident report point coordinates and each accident multiple-place pile number, recording the minimum value of the distance and the corresponding pile number, judging whether the minimum value of the distance is not more than the judging distance corresponding to the pile number, and if so, considering the pile number as the pile number of the accident report point; if not, continuing to execute the step A2;
step A2: determining pile numbers at all curves with the level of 2 in the travelling direction, sequentially calculating the distance between the coordinates of the accident reporting point and the pile numbers at each curve, recording the minimum value of the distance and the corresponding pile number, judging whether the minimum value of the distance is not more than the judging distance corresponding to the pile number, and if so, considering the pile number as the pile number of the accident reporting point; if not, continuing to execute the step A3;
step A3: determining all normal road pile numbers with the level of 3 in the travelling direction, calculating the distance between the coordinates of the accident reporting point and each normal road pile number in a halving searching mode, recording the minimum value of the distance and the corresponding pile number, judging whether the minimum value of the distance is not more than the judging distance corresponding to the pile number, and if so, considering the pile number as the pile number of the accident reporting point; if not, the pile number corresponding to the minimum distance value is still used as the pile number of the accident reporting point according to the nearest principle.
For example, as shown in fig. 5, for P1, assuming that the determination distance of pile number S72 is 20m, the distance d (P1, S72) =10m between P1 and pile number S72, then P1- > S72;
for P2, the vehicle is driven out of the expressway, if the judging distance of the pile number of the normal road is 50m, and the distance d (P2, K200) between P2 and the pile number K200 is less than or equal to 50m, the P2- > K200 is directly judged; if d (P2, K200) >50m, the recent principle still considers P2- > K200.
For P3, the vehicle does not leave the expressway, and the distance d (P3, K200) between P3 and the pile number K200 is less than or equal to 50m, then P3- > K200;
for P4, the vehicle does not exit the highway and is ascending, the distance between P4 and peg number K200 is equal to the distance between P3 and peg number K300, i.e., d (P4, K200) =d (P4, K300), then P4- > K300;
for P5, the vehicle does not exit the highway and is descending, the distance between P5 and peg number K200 is equal to the distance between P5 and peg number K300, i.e., d (P5, K200) =d (P5, K300), then P5- > K200.
From the determination of the associated pile numbers of P4 and P5, it can be seen that: if the distance between the reporting point of an accident and two normal road pile numbers is equal, the pile number which is deviated along the current road direction is used as the belonging pile number.
S104: and highlighting a pile number identifier corresponding to the belonging pile number in a display interface and sending out alarm sound so as to prompt a worker to send notification information to a rescue worker and trigger automatic closing of the alarm sound.
As an embodiment, the present step specifically includes the following substeps:
s1041: jumping the pile number identification corresponding to the belonging pile number in a display interface and sending out alarm sound;
specifically, the protruding form of the stake marks may be set as desired, for example: the color of the protrusion is set, and the flashing form is set for the protrusion, or the jumping form in the present embodiment is set for the protrusion.
S1042: when the jumping pile number identification is detected to be clicked, an accident management page is displayed, notification information is sent to rescue workers through enterprise WeChat, and an automatic closing alarm sound is triggered once the sent notification information is detected.
Specifically, taking the pile number K200 in the uplink direction as an example of the pile number of the accident reporting point:
the reported accident information is pushed to a background management system, and the background management system controls the pile number identification of the pile number K200 in the uplink direction in the display interface to jump and gives out an alarm.
When the pile number identification corresponding to the pile number K200 is detected to be clicked, an accident management page is displayed, the number of accidents, the pile number, coordinate information and the like can be checked, and then related information of the accidents is sent to related rescue departments and personnel through enterprise WeChat. After the enterprise WeChat is sent, the mark is not jumping, and the alarm is closed.
