The invention provides a light source device for reducing coherence between a plurality of lasers and restraining speckle noises, an image display device and a monitoring device. The light source device includes plural light-emitting elements (11a-11f) that emit lights, a wavelength selection element (12) that has plural light selection areas in which wavelength selection is performed for the lights emitted from the plural light-emitting elements (11a-11f), respectively, and selectively reflects a part of the lights emitted from the plural light-emitting elements (11a-11f); a state detecting unit (21) that detects states of the plural light selection areas of the wavelength selection element (12), and a state changing unit (22) that changes, according to the states of the plural light selection areas (A-F) detected by the state detecting unit (21), the states of the light selection areas (A-F)of the wavelength selection element (12) to make wavelengths of the lights selected in the plural light selection areas (A-F) different from one another.

The invention discloses an unmanned helicopter system for patrolling trolly wire routes and towers and a method thereof. The unmanned helicopter system adopts an unmanned helicopter carrying a detection device, a control device and a communication device, and patrols the trolly wire routes and the towers along a trolly wire route passage. The method can cope with complex and changeable surface features to finish detecting the defects of the devices of the trolly wire routes and the towers. The structure of the unmanned helicopter system comprises an unmanned helicopter, a remote controller and a ground control car, wherein, the unmanned helicopter is provided with a flight control system and a patrolling detection system; the two systems are both wirelessly communicated with the ground control car; the ground control car remotely carries out remote control for the unmanned helicopter and analyzes and processes patrolling detection results.

The invention relates to a monitoring device, and particularly to a steel structure construction welding main beam monitoring device. Therefore the invention settles a technical problem of supplying the steel structure construction welding main beam monitoring device which does not require artificial direct monitoring to a steel structure, high monitoring accuracy and no easy danger. The steel structure construction welding main beam monitoring device is characterized in that the steel structure construction welding main beam monitoring device comprises a first mounting board, a second mounting board, etc.; the bottom end of the first mounting board is provided with the second mounting board which is rotatably mounted; the upper part of the first mounting board and the lower part of the second mounting board are provided with mounting holes; and the upper part of the right side surface of the second mounting board is provided with a connecting block. The steel structure construction welding main beam monitoring device can more accurately perform monitoring on the steel structure through the monitoring device; and through a viewing device, an operator can more conveniently view thepositions of a first conical block and a second conical block, thereby determining whether deformation of the steel structure occurs and realizing effects of high accuracy and no easy danger without artificial direct monitoring to the steel structure.
