Curtain wall cleaning robot and working method and control system thereof

The curtain wall cleaning robot comprises a vertical moving mechanism connected with a mooring rope, a body control mechanism connected with the vertical moving mechanism, a cleaning device used for cleaning a curtain wall and a cleaning device adjusting mechanism connected between the body control mechanism and the cleaning device. The vertical moving mechanism is suspended outside the curtain wall through a cable, and lifting or hovering is achieved through friction between the vertical moving mechanism and the cable. When a curtain wall is cleaned, the body control mechanism drives the cleaning device to be close to the curtain wall, then the cleaning device adjusting mechanism adjusts the included angle between the cleaning device and the surface of the curtain wall so that the cleaning device can be attached to the surface of the curtain wall, the cleaning device starts to clean the curtain wall, and meanwhile the vertical moving mechanism controls the machine to move downwards or upwards; and the cleani
