The invention discloses a novel airport assembly pavement system, which includes a field foundation, a base layer arranged on the foundation, a flexible transition layer, and a prefabricated road panel; a method for controlling the flatness precision of the field foundation and the top surface of the base layer, and a flexible transition layer The construction control method, the precise positioning and installation method of the prefabricated pavement, the detachable connection structure of the pavement and the rapid replacement method of the prefabricated pavement realize the accurate and rapid installation, replacement and maintenance of the airport pavement. This system and method improves the quality and durability of the airport pavement, avoids the wet operation of concrete in the construction of the airport pavement, greatly improves the mechanization and intelligence level of construction, effectively reduces the amount of labor, and significantly shortens the on-site pavement construction period. In order to greatly improve the efficiency and convenience of airport track construction, operation and maintenance in areas with poor weather conditions, short construction period and resource scarcity. At the same time, the time required for maintenance and replacement of road panels is greatly reduced, which better meets the needs of high-efficiency operation of busy transport airports.

The invention provides a precisely controlled autonomous flying pesticide spraying unmanned aerial vehicle and its plant protection method. The unmanned aerial vehicle includes a body, four or more rotors, landing gear, a mounting plate, an external medicine box, a control device, and a power supply. . The UAV control device collects environmental data in real time, and performs comprehensive dynamic adjustment based on the environmental data, including adjusting the expansion and contraction of the expansion joint according to the offset angle, and adding the wind speed experience value to the expansion and contraction to improve the spraying accuracy; and adjusting the PWM according to the wind speed. , to increase the amount of spraying, the UAV automatically performs path planning, and automatically returns when the wind speed is too high. The invention can effectively improve the spraying precision and enhance the safety of the drone.

The invention discloses a biological feed manufacturing system which comprises first-order reaction kettles, second-order reaction kettles, a strain fermentation culture tank and a mixer. The first-order reaction kettles and the second-order reaction kettles are used for breeding various strains in a fermentation manner, the various strains are mixed and allowed to ferment by the aid of the strain fermentation culture tank, materials are inoculated with mixed strains and are mixed with one another by the mixer, inoculated and mixed materials in the mixer are loaded on a fermentation vehicle, ferment in an annular fermentation kiln, and completely ferment when the fermentation vehicle moves to a discharging platform, the materials loaded on the fermentation vehicle are unloaded, and the fermented materials can be bagged. The biological feed manufacturing system has the advantages that the inoculated materials which are mixed with one another by the mixer and are loaded on the fermentation vehicle are collected at a certain position of the annular fermentation kiln, then the fermentation vehicle slowly runs to the discharging platform along a conveying rail, the materials completely ferment in the procedure, accordingly, a fermentation procedure and a conveying procedure are combined with each other, and the manufacturing efficiency can be greatly improved; the fermentation vehicle in a unique design and the discharging platform are matched with each other, so that the materials can be automatically unloaded, the work efficiency can be greatly improved, and the degree of dependence on labor can be reduced.
