By setting up a formula
Whether the types of materials purchased by workers are the same as the set types can be analyzed, the workers can be guaranteed to carry out construction according to the content of the contract signed in advance, and the smooth construction is guaranteed; because the material type information on the invoice and the material type information obtained by scanning the two-dimensional code are in information with different dimensions, the character features are extracted by a dimension reduction method of PCA; the principal component analysis method of PCA is used, and as the principal component analysis method is the prior art, the principal component analysis method is not elaborated too much;
whether the material type is changed into other types or not is analyzed according to the comparison condition of the character vectors, and the change information of the material type is obtained in the process in a cosine similarity mode.
In step Z04, if it is detected that the type of the material purchased on the invoice is the same as the type of the material displayed by the two-dimensional code in the construction project, acquiring work task set information of workers in the construction project, wherein the work task set information is represented by D = {1,2,3.i.. n-1, n }, and i and n are the number of workers; acquiring path information formed when an ith worker passes through different position points during working in a historical monitoring video, and generating a first path; when working in the historical monitoring video, the ith worker passes through the path information with the same starting point and different end points compared with the first path, and a second path is generated; obtaining the current prison of the ith workerControlling the path position information in the video to obtain the fact that the ith worker reaches the terminal point after passing through m position points, and forming an included angle according to the connecting line of the m-1 th position point, the m-2 th position point and the m position point when the worker walks
；
Establishing a two-dimensional model, and acquiring coordinates of workers walking to different position points in real time to further acquire a distance K(m-1)(m-2)、K（m-2）m、K(m-1)mTo obtain the included angle
Comprises the following steps:
according to the formula:

If the angle is detected, the included angle is obtained
When the included angle is larger than the preset included angle of the first path and the preset included angle of the second path, and the stay times and the stay time of the ith worker at the terminal position are larger than the preset time and the stay times, the ith worker steals the material; if the angle of the ith worker stays at
When the material is stolen, the ith worker does not steal the material, and the walking path condition of the worker i +1 is checked;
wherein: k(m-1)(m-2)Is the distance between the m-1 th position point and the m-2 th position point, K（m-2）mIs the distance between the m-2 th position point and the m-th position point, K(m-1)mRefers to the distance between the m-1 st position point and the m-th position point,
is referred to as K(m-1)(m-2)And K（m-2）mThe degree of the included angle between the two parts;
it means that the first path is preset with an included angle,
the preset included angle of the second path is included;
when the worker works in the construction site, the working path of the worker is stable and unchangeable, for example: a worker starts from the position of the point A, goes to the position of the point B to mix cement, and distributes the mixed cement to the point C and the point A; if the task of mixing cement for the worker is completed, the worker can be arranged to complete other tasks, such as: the worker starts from the position A, goes to the position D to carry the steel wire, goes to the position E to carry out steel wire winding work and the like, the worker starts around the project, and the path does not change too much, so that the daily task of the worker can be analyzed in the above mode, whether the corresponding paths of the worker are matched or not is further analyzed, and the included angle between the position point and the position point can be obtained by going to a straight line formed by connecting lines at different positions if the working position point is not on the same straight line; if the included angle is detected to be larger than the preset degree, whether a worker steals the material can be distinguished until a result is obtained;
whether a worker steals the material can be easily and simply obtained through the method, if the worker steals the material is directly analyzed from monitoring, the method is very subjective, the result of whether the worker steals the material can be directly judged without knowing the daily task of the worker, and the judgment accuracy is not as good as that of the scheme of the application.
In step Z05, according to the comparison between the work progress of the worker in the current project and the original construction progress, the daily progress of the worker needs to be readjusted, the time consumed for the worker to buy the material again is T1, the number of days of rainfall is set to T2 in advance, the daily task completion time of the originally arranged worker is H1, and the daily task completion time of the current worker is H1+ H2;
and then the construction progress that obtains the workman and actually accomplish does:
W=（Toriginal source-T1-T2-T3）*(H1+H2)*V；
If the fact that the worker completes the construction progress is detected, a first construction price is obtained; if the fact that the worker does not finish the specified construction progress is detected, processing the first construction price to change the first construction price into a second construction price;
the second preset price is: f = Q- (P-W) × L;
wherein: t isOriginal sourceThe method comprises the following steps of A, F, P, L and T3, wherein the method refers to the originally specified period of a project, F refers to a second construction price, Q refers to a first construction price, P refers to the total construction progress amount which a worker has to complete on the project, L refers to a price deduction coefficient, and T3 refers to the past period;
the completion time limit and construction price of each project are determined before construction, and if the set time limit is exceeded, the construction price is rearranged, so that in the scheme of the application, an engineer knows that the time for workers to work needs to be immediately rearranged due to the theft of materials or the purchase error of the types of the materials, and the construction is not delayed and the quality of the construction is guaranteed.
Example 1: acquiring work task set information of workers in a construction project, wherein the work task set information is represented as D = {1,2,3 }; acquiring path information formed when a 1 st worker passes through different position points during working in a historical monitoring video, and generating a first path; when working in the historical monitoring video, the 1 st worker passes through the path information with the same starting point and different end points compared with the first path, and a second path is generated; obtaining the path position information of the 1 st worker in the current monitoring video, obtaining that the 1 st worker reaches the terminal point after passing through the 3 position points, and forming an included angle according to the connection line of the 2 nd position point, the 1 st position point and the 3 rd position point when the worker walks
(ii) a Obtaining the coordinates of the worker at the 2 nd position point, the 1 st position point and the 3 rd position point as { (a)1,b1)、（a2,b2）、（a3,b3) H = { (1200,1600), (1450,1000), (1600,1150) }, detection of the first path presetThe included angle is 15 degrees, and the second preset included angle is 17.5 degrees
Establishing a two-dimensional model, and acquiring coordinates of workers walking to different position points in real time to further acquire a distance K(m-1)(m-2)、K（m-2）m、K(m-1)mObtaining the included angle of
：
Calculating to obtain K(m-1)(m-2)=650;K（m-2）m=602;K(m-1)m=212;
And 19>17.5>15, and if the time and the number of times that the first worker stays at the specified position exceed the preset time and the preset number of times, the 1 st worker steals the material.
Example 2: comparing the work progress of a worker in the current project with the original construction progress, readjusting the daily progress of the worker, acquiring the time taken for the worker to buy materials again, wherein the time taken for the worker to buy the materials again is T1=1.5 days, the number of days of rainfall is preset to be T2=2 days, the daily task completion time of the originally scheduled worker is H1=8, the daily task completion time of the current worker is H1+ H2=8+2=10, and the construction coefficient of each day is 1.25; the preset construction progress is P =150
And then the construction progress that the workman needs to accomplish is:
W=（Toriginal source-T1-T2-T3）*(H1+H2)*V=106.25；
If 106.25<150 is detected, the first construction price is processed to become a second construction price;
