8. Introduction to system functions
【Project Personnel Management】
1. Project management: project name, name of construction unit, project address, total cost, total area, construction permit, start date, planned completion date, project status, etc.
2. Personnel information management: Supports the collection of ID cards and face information; maintains basic information, certificate information, contract information, training information and other data.
3. Attendance management: Supports multiple check-in methods such as safety helmets and mobile phones, records entry and exit times, and counts working hours; partition management, attendance records, and salary payment.
4. Access control management: Establish labels for special personnel and management personnel to facilitate personnel inquiry and unified management.
5. Safety education: Wireless WIFI is provided at the construction site. Workers need to be certified and answer built-in questions before accessing the Internet. After passing the certification, they can access the Internet. The system pushes different types of questions or video content according to the type of logged-in personnel. Questions or videos are set differently according to their importance. Weight, push randomly.
