The invention provides a dynamic energy-saving resource scheduling system and method for a distributed cloud computing platform. The system comprises a cloud server node of the distributed cloud computing platform. The cloud server node is respectively connected with a global controller and a monitoring system; the global controller and the monitoring system are connected with a modeling analysis module respectively; the monitoring system comprises an energy consumption monitoring module, a flow monitoring module and a resource monitoring module; a node controller operates on the cloud server node. The system and method aim at cross-domain distribution characteristics and comprehensive energy-saving resource scheduling demands of the distributed cloud computing platform, and the effect of reducing energy consumption of a server and the network at the same time is achieved.

The invention discloses a system and a method for automatically adjusting the projection brightness. The method includes A, acquiring ambient brightness parameter values via a brightness sensor and correspondingly transmitting the ambient brightness parameter values to a microprocessor; B, enabling the microprocessor to correspondingly transmit the ambient brightness parameter values to a CPU (central processing unit); C, enabling the CPU to carry out brightness compensation according to the ambient brightness parameter values and transmitting compensated brightness parameters to the microprocessor; and D, enabling the microcontroller to control a projection module to drive a projection lens to carry out projection according to the compensated brightness parameters. The system and the method have the advantages that the ambient brightness of an environment where projection is required is detected by the brightness sensor, the current ambient brightness values are acquired, a brightness compensation algorithm is called by the CPU to compensate the current ambient brightness, required compensated brightness values are acquired, and the microprocessor controls the projection module to drive the projection lens to carry out projection; and the projection brightness can be automatically adjusted according to different ambient brightness, and problems of poor effect and user experience and troublesome operation of a manual brightness adjusting mode are solved.

A hanger includes an elongated member having a rod with a plurality of positioning portions spaced in a vertical direction. An engaging portion is formed on a bottom of the rod for engaging with an engagement portion. A coupling block includes a connecting head. The coupling block further includes a body and a resilient plate that are located below the connecting head. The body and the resilient plate together define a passageway having an opening in a lower end thereof. The rod is slideable in the passageway in the vertical direction. The resilient plate includes a free end having a hook that is spaced from the body. At least a portion of the hook extends into the passageway. The hook is releasably engaged with a selected one of the positioning portions. The resilient plate is operable to disengage the hook from the positioning portions.

The invention discloses an anti-icing device for power transmission lines. The anti-icing device mainly comprises a base, a support frame and a rain cover, wherein a drive shaft in the vertical direction is arranged on the support frame, the top of the drive shaft is connected with a wind cup for collecting wind power by a rod, an upper drive gear and a lower drive gear are fixedly arranged at the middle part of the drive shaft, the lower end of the drive shaft is connected with a steering guide device, an upper roller compound gear is arranged on the support frame on one side between the upper drive gear and the lower drive gear, and the upper roller compound gear is driven by the upper drive gear or the lower drive gear under the control of the steering guide device. The anti-icing device can travel on overhead ground wires by means of wind power without other power and travel positively and negatively by means of the steering guide device, and when the anti-icing device travels, a brush clears frozen rain, soft rime and flying snow attached to the overhead ground wires, so that the overhead ground wires are prevented from icing.
