S200, screening the operation route data of the slag car and the mixer truck to screen out the operation route data of the slag car and the mixer truck in operation;
wherein the screening basis of the operation route data of the muck truck is as follows: the number of times of parking is larger than a first time threshold value, and the accumulated parking time is larger than or equal to a first time threshold value.
Wherein the screening basis of the operation route data of the mixer truck is as follows: the number of times of parking is greater than the second time threshold value, and the accumulated parking time is greater than or equal to the second time threshold value.

Therefore, early warning can be carried out on the muck vehicle in the construction site, and accidents around the construction site are reduced; can describe the building site region automatically, improve artifical survey and drawing efficiency. Vehicle operation data highly correlated to a construction site such as suspected muck trucks can also be provided for insurance companies.
Therefore, the position of the construction site is positioned by the muck truck and the stirring truck, so that the positioning accuracy is improved.
Preferably, as shown in fig. 2, the step S300 of determining the intersection area of the slag car and the mixer truck according to the operation route data of the operating slag car and the mixer truck comprises:
s310, screening out the operation route data of the running slag car, and screening out the operation route data of the slag car, wherein at least one stop point of the operation route data falls into the mixing plant fence;
in one operation of the muck truck, if one parking area is overlapped with the mixing station, the operation is considered to be road repairing and not to be a construction site.
S320, identifying a muck truck operation area according to the operation route data of the screened muck truck, wherein the muck truck operation area comprises at least N stopping points of the muck truck for more than M times, and M, N is a natural number greater than 2;
that is, if there are at least N stops of the slag car in an operating area, and the stop point of each slag car is greater than M, the area is considered as the operating area of the slag car.
Wherein, the values of M and N are determined according to actual conditions.

and for a slag car operation area, acquiring all the stop point data in the operation area, and carrying out grid clustering on all the stop points according to the precision of S meters on the stop point data to obtain a first external polygon. Wherein, the value of S is determined according to the actual situation.
S340, after at least P stopping points of the agitating trucks exist in the preset distance of the external polygon of the operation area of the muck truck, the operation area of the muck truck is judged to be the crossing area of the muck truck and the agitating trucks, and P is a natural number larger than 2.
That is, if there are a total of P stopping points of one or more trucks near the circumscribed polygon, the muck truck operating area is considered to be an intersection area, i.e., a construction site.
Therefore, the operation area of the slag car is generated firstly, and then the cross area is determined according to the stop point of the stirring car near the operation area, so that the operation is simple and convenient.
Preferably, as shown in fig. 3, S400, acquiring a road segment around the intersection region, and generating a worksite boundary line and a worksite entrance and exit of the intersection region;
s410, acquiring road sections around the intersection area and the operation route data to which the internal stop points of the intersection area belong;
wherein, the road sections around the crossing area need to be obtained through map data; wherein, if a certain road section can be determined according to two adjacent intersections.
The data of the operation route to which the internal stop point of the intersection area belongs is obtained, that is, if a stop point is located inside the intersection area, the data of the operation route to which the stop point is located is obtained.
The acquired operation routes have repeated conditions, and the repeated operation routes can be preprocessed and combined.
S420, intercepting the stop point data before the internal stop point, wherein the distance between the stop point and the internal stop point is smaller than a first distance threshold;
an operation route comprises a plurality of stop points which are arranged in sequence from front to back according to the movement direction; if a stop point is in the interior of the cross area, intercepting the stop point data in the first half part of the operation route of the stop point; in this way, since this stop point is inside the intersection area, the first half of all its operation routes is most likely in the process of moving from the outside to the inside of the intersection area, so that an accurate judgment result can be obtained.
By setting the first threshold, only the stop data close to the stop can be reserved, and the stop data is the actually required data, so that the purposes of simplifying the data and improving the efficiency are achieved.
It should be noted that, if a plurality of stop points of one operation route are all located inside the intersection area, the stop point data of the operation route may be obtained many times, which is easy to cause data duplication, not only reduces efficiency, but also causes errors. Therefore, each operation route can be intercepted only once, thereby avoiding repeated interception.
S430, acquiring a second external polygon and a boundary road section according to the intercepted stop data and the intercepted road section;
clustering can be performed on the basis of the first circumscribed polygon through a similar grid clustering method, so that a second circumscribed polygon is obtained. The specific clustering method is not described herein again.

S450, calculating an intersection point of the driving track corresponding to the intercepted stop point data and the construction site boundary line, and taking the intersection point as a construction site entrance;
therefore, a plurality of entrances and exits of a construction site can be accurately calculated through the characteristics of the surrounding road sections and the operating route of the engineering vehicle, and therefore the accuracy of early warning is greatly improved.

s431, generating a second external polygon on the outer side of the first external polygon according to the intercepted stop point data;
s432, if the road section is intersected with the second external polygon, taking the road section as a construction site boundary section of an intersection region;
and S433, traversing all the road sections to obtain the boundary sections.
Therefore, the construction site boundary section can be confirmed through the road section and the second external polygon, so that the construction site boundary can be accurately divided, and the construction site entrance and exit can be accurately positioned.
Preferably, as shown in fig. 5, S500, acquiring parking data of the muck truck inside the worksite at present and sending out early warning information according to the parking data includes:
s510, obtaining the current stopping time and stopping points of the muck truck in the construction site;
s520, if the parking time is larger than a first time threshold value, first early warning information is sent after a starting signal of the muck truck is detected;
like this, be greater than the very long time threshold value, it is very long to mean that the dregs car parks time, will leave the building site and carry out normal work, consequently carries out first early warning to it, avoids it to take place traffic accident at the building site access & exit.
Preferably, the S500, acquiring current parking data of the muck truck inside the construction site and sending out early warning information according to the parking data, further includes:
s530, if the stopping time is larger than a second time threshold, obtaining a first track point of the muck car after the muck car is started, and calculating an included angle between the stopping point, the first track point and the entrance and exit;
s540, after the included angle between the stop point, the first track point and the entrance and the exit is an obtuse angle, calculating the distance between the first track point and the corresponding entrance and the exit;
an obtuse angle means that the direction of travel of the slag car is the doorway from which it is likely to leave the site.
It should be noted that, a plurality of building site entrances and exits are provided, so that calculation can be performed one by one, and as long as one of the entrances and exits is an obtuse angle, data of the entrance and exit is obtained, and subsequent distance judgment is performed.
S550, sending second early warning information when the distance between the first track point and the corresponding entrance and exit is smaller than a second distance threshold;
therefore, the muck vehicle is about to exit from the gateway, and second early warning information needs to be sent to avoid traffic accidents at the gateway of the construction site.
And S560, after the distance between the first track point and the corresponding passageway is greater than or equal to the second distance threshold, updating the data of the first track point, and recalculating the included angle between the stop point and the first track point and between the passageway and the passageway.
Namely, after the muck vehicle enters the construction site, the muck vehicle can stop at least once, after the muck vehicle is monitored to stop for the first time (the stopping time is greater than a preset threshold), the first track point P of the muck vehicle running again is monitored, an included angle between the stopping point-P point-entrance point is calculated, if the included angle is an obtuse angle and the distance between the P point-entrance and exit is smaller than the preset threshold, the muck vehicle is considered to be about to run away from the construction site, and if the distance between the P point-entrance and exit does not meet the condition, the next track P point is continuously calculated until the track point runs away from the construction site.
Like this, through the distance of contained angle and access & exit, can distinguish the dregs car that the completion of unloading is about to roll off the building site to carry out timely early warning.
