Example 2
The embodiment provides an intelligent construction site personnel health management method which is realized by adopting a face recognition machine, a user side small program and a service center. The user side applets include a worksite general staff applet and a manager applet.
As shown in fig. 2, for a worksite stationary person, the method specifically includes:
and S1, creating a project, filling in basic information of the project, configuring an IP address and an SN code of the gate, and generating a two-dimensional code exclusive to the project.
S2, scanning the two-dimension code exclusive to the project by the user, and prompting the user to register first if the two-dimension code is not registered; if the user is not registered, the personal information of the user is acquired by the service center station to obtain a face characteristic value and a personnel characteristic code.
As shown in fig. 3, for a job site stationary person, face data and basic information are required to be input during registration, and the basic information includes information such as a mobile phone number and an identification number. And the data are transmitted to the face recognition machine at the project according to the project to which the user belongs to be stored.
As shown in fig. 4, for the temporary staff at the construction site, only basic information, such as a mobile phone number, an identification number, and the like, is input at the time of registration. The registered data are issued to a face recognition machine at a specific project, the face recognition machine generates a two-dimensional code of temporary personnel according to the registered data, and when the temporary personnel enter the site, the temporary personnel start the system by displaying the two-dimensional code for scanning.
And S3, the manager checks the personal information of the user and sends the face characteristic value and the personnel characteristic code of the user to the face recognition machine.
And S4, the face recognition machine stores the face characteristic value and the personnel characteristic code.
S5, scanning the face of the personnel on site to obtain the face image and the temperature measurement data, comparing the face according to the face characteristic value by the face recognition machine, if the comparison is successful, searching the personnel characteristic code corresponding to the face characteristic value and uploading the personnel characteristic code and the temperature measurement data to the service central station; if the comparison fails, the user is prompted to be a stranger, and the user is requested to register first.
S6, the business center station acquires the health code state of the user through the health code server or a third-party program, verifies the temperature measurement data of the user according to the health code, stores the current passing record of the user when the verification result is normal, and sends a door opening instruction to the entrance guard gate; and when the verification result is abnormal, storing the record and sending early warning information to the gate and management personnel.
S7, opening a gate and allowing people to pass; or the gate is not opened, and the early warning information is played.
In S6, when the check result is abnormal, sending a door opening refusing instruction to the entrance guard gate, simultaneously sending real-time early warning information to a manager, and uploading the abnormal check result to an early warning center of a manager user side, wherein the early warning information comprises the mobile phone number of the abnormal person; and the manager performs offline checking according to the mobile phone number of the abnormal person, and uploads the checking result to the early warning center in the form of text and picture.
Further, after receiving the early warning information, the manager determines whether to perform isolation processing through offline checking, fills in processing conditions and photos, uploads the processing conditions and photos to the service center station, and stores early warning processing results by the service center station to form a management closed loop.
When the management personnel user side registers the project, each project generates a special project two-dimensional code for the common personnel user side to scan the code associated project, and when the same personnel enters and exits different projects, only the special project two-dimensional code needs to be scanned to perform the associated project, and then the health report can be performed. Different enterprises integrate the health data reported by each project according to the project dimension to form epidemic prevention big data for supporting enterprise epidemic prevention management.
The embodiment can realize the automatic management and control of equipment, and is high-efficient, use manpower sparingly, be difficult for makeing mistakes, can not omit, has improved building site epidemic prevention management efficiency greatly.
