the embodiment of the invention does not need to arrange special persons to manage the construction personnel entering the construction site, thereby reducing the labor cost, avoiding the mistakes and omissions of manual supervision and improving the efficiency of site epidemic situation prevention and control.
In one embodiment, the acquisition module 1 performs the following operations:
when the construction personnel enter the field, acquiring a first person image of the construction personnel in an entrance area of the construction site;
identifying a face ID corresponding to the construction personnel in the first person image based on a face identification technology;
and inquiring a preset face ID-personnel information base, determining personnel information corresponding to the face ID, and finishing acquisition.
The working principle and the beneficial effects of the technical scheme are as follows:
the method comprises the steps of obtaining a first person image of a construction person in an inlet area of a construction site (for example, a picture containing the construction person shot at the inlet of the construction site), identifying a plurality of face IDs (3D faces) based on a face identification technology (the face identification technology belongs to the prior art and is not repeated), inquiring a preset face ID-person information base (a database for storing the corresponding relation between the plurality of face IDs and person information), and obtaining the person information of the construction person in the first person image.
In one embodiment, obtaining a first person image of the construction person at the construction site entry area includes:
acquiring a preset monitoring trolley dynamic distribution diagram corresponding to the building site, and determining a first monitoring trolley with the shortest distance to the inlet area from the monitoring trolley dynamic distribution diagram;

according to the embodiment of the invention, the first monitoring trolley is obtained to acquire the first person image of the building personnel entering the building site, so that the problem that the person image is difficult to distinguish due to the fixed shooting angle of the camera device at the fixed position is avoided, and the applicability is improved.
In one embodiment, controlling the first monitoring cart to enter the entry area captures a first person image of the construction person within the entry area, comprising:
controlling the first monitoring trolley to perform dynamic cruise three-dimensional scanning in the inlet area to obtain three-dimensional information of the inlet area;
constructing a dynamic three-dimensional model of an inlet area based on the three-dimensional information;

The working principle and the beneficial effects of the technical scheme are as follows:
when the first monitoring trolley collects the first person image, the collected image may not be usable due to the problem of the collection angle (for example, the construction person exists in the image, but the construction person can not completely see the wearing condition of the mask because the construction person lowers the head or intentionally avoids the trolley monitoring, etc.) during the construction process; therefore, a solution is urgently needed;
controlling a first monitoring trolley to perform dynamic cruise three-dimensional scanning on an inlet area to obtain three-dimensional information of the inlet area, constructing a dynamic three-dimensional model of the inlet area, determining the total change amount (for example, 30 degrees) of the face orientation of a personnel three-dimensional model corresponding to a construction worker in a preset time (for example, 3S) from the dynamic three-dimensional model of the inlet area (the monitoring robot is provided with a camera device and can be collected based on the camera device), if the total change amount is smaller than or equal to a preset total change amount threshold value (for example, 45 degrees), obtaining the current shooting orientation of the first monitoring trolley, establishing a first space rectangular coordinate system by taking the space central position of the dynamic three-dimensional model of the inlet area as an origin, obtaining a first vector representing the face orientation and a second vector representing the shooting orientation, and determining a shooting angle based on the first vector and the second vector, if the shooting angle is within a preset shooting range (for example, 180 degrees), the first monitoring trolley shoots the building personnel to obtain a first personnel image;
the embodiment of the invention is based on the face orientation of the building personnel and the shooting orientation of the first monitoring trolley, avoids the problem that the identity recognition degree of the building personnel is not suitable to be low due to the shooting angle, improves the effectiveness of obtaining the image of the first personnel, and also reduces the power consumption of the first monitoring trolley.

determining the risk types of the construction personnel according to a preset risk type judgment rule based on the risk index;
wherein the risk types include: non-risk personnel and risk personnel.
The working principle and the beneficial effects of the technical scheme are as follows:
generally, a construction worker with a risk trip is controlled by a relevant department before entering a construction site, but due to the hysteresis of epidemic situation announcement information (for example, the next day when the construction worker arrives at the construction site, and a trip area where the construction worker arrives reports a confirmed case), the risk worker cannot detect the situation in time, and meanwhile, when the worker has a trip of a city around the epidemic situation area, the risk worker also has corresponding risks; therefore, a solution is urgently needed;
