Construction site monitoring mode determination method and system

The invention provides a construction site monitoring mode determination method and system, wherein the method comprises the steps: comparing a positioning position where each operation vehicle generates a loading behavior with a pre-obtained approved construction site region, and taking a positioning position outside the approved construction site region as a target position; encoding the target position, and combining areas to which a plurality of adjacent codes belong to generate a target construction site area; according to the number and frequency of all the operation vehicles entering the target construction site area, calculating the suspicious degree that the target construction site area is a concealed construction site area; and determining a monitoring mode of the target construction site area according to the target position and the suspicious degree included in the target construction site area. According to the method, the monitoring range and the suspicious degree that the target construction s
