The invention discloses a crude fiber reinforcement bituminous mixture used for a bituminous road surface. The crude fiber reinforcement bituminous mixture is prepared from, by weight, 1000 parts of bituminous mixtures and 2-10 parts of composite crude fibers, wherein the diameter of the composite crude fibers is 0.1-2 mm, and the length of the composite crude fibers is 20-200 mm. The crude fibers can modify bitumen and form a powerful mechanical system with the bituminous mixtures, and in this way, the capacity of the bituminous road surface in resisting heavy loads and excess loads is improved by times, and the service life of the bituminous road surface is prolonged by times.

The invention relates to a mobile multi-stage hydraulic-drive pneumatic spray dust-settling truck, mainly solving technical problems of high investment caused by individual use of spray dust-settling devices and poor effect caused by common use of the spray dust-settling devices due to far distance on conditions of multiple and dispersed dust source points, variable dust source locations and complicated conditions of dust sources. The technical scheme includes that a water storage tank is connected with a high-pressure water pump through a water pipe and high-pressure water is pumped to a spraying assembly; a hydraulic station is connected to a hydraulic motor of a mist spraying device through a high-pressure oil pipe to drive an impeller of axle-flow fans to generate high-pressure air flows, the high-pressure air flows send mist to a dust working face, and high-pressure oil of a hydraulic station is connected to a hydraulic cylinder; the mist spraying device is lifted and then is driven to oscillate around a rotating bearing by a motor and a reduction gearbox via a rotational driving gear; a carriage engine drives a power generator through a double-output transmission in a gear shifting manner so that power required for system running is obtained. The mobile multi-stage hydraulic-drive pneumatic spray dust-settling truck is mainly used for far-distance large-range dust settling and removing and firefighting in fugitive emission fields such as tunnel heading, blast mining, loading, crushing and unloading.

The invention discloses a method and a system for sensing motion gestures of a moving body. The method and the system are mainly designed for comprehensively and efficiently sensing all the information of the motion gestures of the moving body. The method comprises the following steps of: continuously capturing images of a reference surface when the moving body is in a moving state; calculating light stream information in the images according to the captured continuous images; and obtaining the motion gestures of the moving body based on the calculated light stream information. The system and the method can sense all the information of the motion gestures of the moving body, and can provide more comprehensive and efficient motion gesture information for flight attitude monitoring and control on airplanes, earth surface and terrain measurement, and motion gesture monitoring on other objects like jigs or cutters.
