Control method of solar anti-overheat shading system

The invention relates to a solar anti-overheat shading system, comprising a mechanical control switch, a poke rod arranged on the mechanical control switch, a motor, a winding roller, a hauling rope, an up-shift sliding ring, a fixed ring, a down-shift sliding ring, a plurality of pulleys and a roller shutter. The winding roller is connected with a rotating shaft of the motor, one end of the hauling rope is connected with the winding roller, the other end of the hauling rope is connected with one end of the roller shutter through the plurality of pulleys, the roller shutter is connected with the motor through the winding roller, the up-shit sliding ring is connected with the poke rod, the down-shift sliding ring is connected with the poke rod, the fixed ring is fixed on the hauling rope, and the mechanical control switch is provided with a start-up gear and a return gear. The solar anti-overheat shading system is a control system with quite low power consumption, in addition, the power is turned on only at the moment when the system is overheated or the overheating of the system is relieved, when finishing actions, the solar anti-overheat shading system turns the power off automatically and mechanically; and the element in the solar anti-overheat shading system is just a common switch, the cost is low, the system is simple, and the reliability is high.
