Aiming at problems of power loss and unattended safety issues in university laboratories and company departments that workstation power switches are not shut down in-time

in order to control the power supply at the corresponding workstation

a power switch system based on OpenCV and Visual Basic is proposed. In the overall system

human information input and image matching are performed mainly through face recognition

and the accepted data information is sent to the Visual Basic host computer client through the serial port

and then processed through the wireless RF network

through the database comparison. The actual test proves the feasibility and practicality of the scheme.
