Intelligent all-weather actively safety early warning system and early warning method thereof for ship running

The present invention discloses an intelligent type all-weather initiative safety early-warning system of ship running and an early-warning method thereof. The early-warning system consists of a target sampling unit, a system central processing unit, a display unit, a singlechip and a safety early-warning unit. The early-warning method comprises the following steps that: a, the system is actuated; b, the target is sampled and a digital signal is processed; c, a system decision-making unit obtains information from a to be combined with the information form b to process for initiative safety early-warning decision-making analysis and calculation to obtain a final shunning proposal, and a display and an acoustic-optic warning terminal are used for the initiative safety warning synchronously. The present invention improves the sense ability of ship operating personnel to the navigation environment and the initiative safe navigation guarantee capability of the ship under the circumstance of bad visibility greatly and helps the ship operating personnel for making decision, so as to reduce the error of ship operating, improve the success rate of ship initiative shunning bump, reduce or avoid the occurrence of the traffic accidents such as ship collision, ship-against-bridge, aground, etc., and ensure the safety of the navigation transportation.
