Phase sequence table detection device and method based on image recognition and computer equipment

The invention relates to a phase sequence table detection device and method based on image recognition and computer equipment, and relates to the technical field of instrument detection. The device comprises a signal source generation unit used for outputting a target signal with any phase sequence, wherein the target signal comprises a current signal or a voltage signal of a three-phase alternating current; the image acquisition unit is used for acquiring an acquisition image corresponding to the detected phase sequence table; the computer control system is used for controlling the signal source generation unit to output a target signal, identifying the collected image, obtaining first phase sequence state information displayed by the detected phase sequence table, determining second phase sequence state information corresponding to any phase sequence of the target signal, and sending the second phase sequence state information to the detected phase sequence table. And the computer control system is also use
