Description

Fishing boat operation safety early warning method, system and storage medium Technical Field The invention relates to the technical field of ship safety early warning, in particular to a fishing boat operation safety early warning method, a fishing boat operation safety early warning system and a storage medium. Background In the event of a ship collision, the collision of a fishing vessel with other vessels has been a significant proportion. The reason why the fishing boat collides with other boats is mainly that when the crewman catches the boat in the daytime, the cab is not on duty, the fishing boat crewman is busy catching and can not receive the early warning signal, and when other boats, such as a commercial boat, send warning or whistle warning to the direction of the fishing boat through the searchlight, the fishing boat crewman sleeps at a cabin or catches the boat, and the unmanned watch can not break away from danger. In addition, when the fishing boat sails at night, tired crews rest in the cabin and lose vigilance, no personnel is on duty in the cab, no collision early warning information of the cab is acquired, and no anti-collision measures can be made. Meanwhile, emergency situations that crews carelessly fall into water due to strong wind, high waves and the like can occur during the sailing of the fishing boat, the existing marine communication equipment is difficult to timely warn other crews, and the specific positions of the crews cannot be known in a short time, so that rescue opportunities are delayed. Sometimes, even if a person is found to fall into water carelessly, the person cannot locate the person accurately in time and send out help seeking information, so that an drowning event is caused. Safety problems during sailing operations of fishing vessels are prominent. In the related art, old communication equipment such as interphones and marine phones are mainly used for carrying out the contact of all departments, so that the communication efficiency is low, the carrying convenience is poor, the contact cost is high, and the emergency situations such as ship collision prevention and drowning of crews are difficult to deal with. How to timely and accurately perform safety precaution in the operation process of the fishing boat becomes a problem to be solved. Disclosure of Invention In order to solve at least one of the technical problems, the invention provides a fishing boat operation safety pre-warning method, a fishing boat operation safety pre-warning system and a storage medium, which can realize accurate safety pre-warning in the fishing boat operation process and effectively reduce the occurrence probability of boat accidents. In one aspect, the embodiment of the invention provides a fishing boat operation safety pre-warning method, which comprises the following steps: Acquiring crew behavior data acquired by a wearable device, wherein the wearable device is worn on a crew; performing crew behavior recognition according to the crew behavior data to obtain crew state data; analyzing and obtaining a crewman defense level according to the crewman state data; Acquiring preset ship navigation data, wherein the preset ship navigation data comprise target fishing boat navigation data and other ship navigation data; performing collision analysis according to the preset ship navigation data to obtain a ship collision risk level; Calculating to obtain a fishing boat comprehensive safety risk level according to the crew defending level and the boat collision risk level; and carrying out ship safety pre-warning according to the comprehensive safety risk level of the fishing ship. The fishing boat operation safety pre-warning method has the advantages that behavior data of a crew are acquired through the wearable equipment worn on the body of the crew, so that behaviors of the crew are identified according to the behavior data of the crew, and crew state data are obtained. Then, the crew state data obtained through recognition is analyzed to obtain the defending capability of the crew to the danger, namely the defending grade of the crew. Meanwhile, the preset ship navigation data are acquired, collision analysis is carried out through the acquired target fishing boat navigation data and other ship navigation data, and the collision risk of the fishing boat and other ships, namely the ship collision risk level, can be obtained in real time. Further, according to the method, the fishing boat comprehensive safety risk level is obtained through combination calculation of the crew defense level and the boat collision risk level, so that the accuracy of judging the fishing boat safety risk is effectively improved in a mode of combining the crew self state and the collision risk state in the fishing boat sailing process. Then, the embodiment carries out the ship safety pre-warning according to the comprehensive safety risk level of the fishing boat, and realizes accurate safety pre-warning
