The invention discloses an electric power cross-system interactive quality monitoring platform based on a visualization technology. The invention relates to the related technical field of power systems. The platform comprises a monitoring center, a handheld terminal, a microphone, a camera, a GPS terminal, a loudspeaker, a display screen and an alarm. A central processing unit, a receiving module,a storage module, a video comparison module, a wireless communication module and an alarm control module are arranged in the monitoring center, and the input end of the central processing unit is electrically connected with the output end of the receiving module. According to the invention, conditions of a construction site can be transmitted to the display screen in real time through the camera;through the video comparison module and the monitoring personnel, whether the video on the display screen meets the construction standard or not can be compared; the monitoring personnel can be reminded of the problem of on-site construction through the alarm, meanwhile, through the cooperative arrangement of the microphone and the loudspeaker, the monitoring personnel can call and stop illegal construction on the construction site in real time, and the construction quality problem caused by illegal construction can be avoided.
