The invention provides an intelligent multiparameter-monitoring buoy device. The intelligent multiparameter-monitoring buoy device comprises buoy equipment, water quality monitoring equipment, communication equipment and power supplying equipment, wherein the buoy equipment is used for enabling the whole buoy device to float on the surface of water, the water quality monitoring equipment is used for monitoring water quality, the communication equipment is used for realizing data transmission between the water quality monitoring equipment and a shore-based main station side and positioning the water quality monitoring equipment and the shore-based main station side, and the power supplying equipment is used for supplying power. According to the intelligent multiparameter-monitoring buoy device, by adopting an embedded-type low-power-consumption design, the integral volume of an instrument compartment and a buoy is reduced; by adopting an intelligent operation mode, the timed, continuous or specified monitoring on water quality is realized; by adopting intelligent electrical quantity management, the effective operation of a solar power supplying system is realized; by adopting a multi-mode mutually-standby communication mode, the real-time property of data is improved, and the risk of out-of-touch is lowered; a sensor with a self-cleaning device is adopted, and intelligent analytical judgment is carried out by integrating a variety of information, so that the quantity of field maintenance is minimized; and the buoy is subjected to integrated protection in multiple manners such as electricity, sound, light and the like, so that the influence on the safety of the buoy caused by marine environments, fishery activities and the like is lowered and prevented.
