In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
The invention discloses a large data-based research and analysis method for a fishing ship, which is shown in fig. 1 and comprises the following steps:
s102: acquiring actual parameter values of all real-time environmental factors of the fish-involved ships in the investigation process, and analyzing the actual parameter values of the real-time environmental factors to obtain a real-time environmental influence factor set;
S104: constructing a prediction model, guiding the real-time environment influence factor set into the prediction model for prediction to obtain preset operation parameters of the fish-involved ship, obtaining the real-time operation parameters of the fish-involved ship, and obtaining an abnormal operation parameter set based on the preset operation parameters and the real-time operation parameters;
s106: acquiring performance information and investigation task information of the fishing vessel, and determining association abnormal equipment based on the performance information, investigation task information and abnormal operation parameter collection;
s108: and searching a big data network based on the relevance abnormal equipment to obtain a historical regulation scheme when the relevance abnormal equipment appears in the investigation process of the fishing ship, screening the historical regulation scheme to obtain a regulation scheme corresponding to the highest regulation and control efficiency, and outputting the regulation scheme corresponding to the highest regulation and control efficiency.
In a preferred embodiment of the present invention, actual parameter values of each real-time environmental factor of the fishing vessel during investigation are obtained, and the actual parameter values of the real-time environmental factors are analyzed to obtain a real-time environmental impact factor set, as shown in fig. 2, specifically:
S202: acquiring environmental factors influencing the investigation of the fishing vessels and corresponding influence thresholds thereof through a big data network, binding the environmental factors and the corresponding influence thresholds thereof to obtain environmental factor data packets, establishing a database, and importing the environmental factor data packets into the database to obtain a characteristic database;
s204: acquiring actual parameter values of real-time environmental factors of the fish-involved ships in the investigation process, and importing the actual parameter values of the real-time environmental factors into the characteristic database so as to compare the actual parameter values of the real-time environmental factors with influence thresholds in corresponding environmental factor data packets;
s206: and if the actual parameter value is larger than the corresponding influence threshold value, marking the real-time environment factors with the actual parameter value larger than the corresponding influence threshold value as real-time environment influence factors, and converging the real-time environment influence factors to obtain a real-time environment influence factor collection.
It should be noted that, in the process of investigation operation of the fishing vessel, the operation effect of the fishing vessel is affected by environmental factors, for example, when the flow rate of the water body is too large, the difference between the fishing net and the set operation path and the operation shape is too large, so that the operation effect is affected, and the deviation is caused in the investigation obtained fishery resource data. The environmental factors include, but are not limited to, water flow rate, wind speed, water pressure, temperature and pressure, etc. The real-time environmental factors are screened by the method to obtain the real-time environmental influence factors influencing the current operation effect of the fishing vessels, so that the investigation analysis precision and reliability of the operation effect of the fishing vessels are improved.
In a preferred embodiment of the present invention, a prediction model is constructed, the real-time environmental impact factor set is imported into the prediction model for prediction, so as to obtain a preset operation parameter of the fish-involved ship, obtain the real-time operation parameter of the fish-involved ship, and obtain an abnormal operation parameter set based on the preset operation parameter and the real-time operation parameter, specifically:

if the operating parameter deviation value is larger than the preset deviation value, marking the real-time operating parameter corresponding to the operating parameter deviation value larger than the preset deviation value as an abnormal operating parameter, and extracting and converging the abnormal operating parameter to obtain an abnormal operating parameter set.
It should be noted that, during the investigation operation of the fishing vessel, if the operation parameters of the fishing vessel are affected by one or more environmental impact factors, the operation parameters of the fishing vessel will change to a certain extent, and when the operation parameters change within a certain range of change, this is a normal situation. If the wind speed and temperature and pressure of the working environment suddenly increase when the fishing vessel is in operation, the working path of the fishing net can deviate to a certain extent, but the deviation degree is in a certain range, which belongs to a normal phenomenon, and the deviation degree range can be obtained from a big data network (namely, normal operation parameters). By the method, abnormal operation parameters of the fish-involved ship in the operation investigation process under the influence of the real-time environmental influence factors can be rapidly judged, so that equipment for predicting faults of the fish-involved ship in the operation investigation process is further analyzed, a corresponding regulation and control scheme is made, the operation investigation effect of the fish-involved ship is further ensured, and reliable data are provided for subsequent analysis of fishery resource quantity.

s304: removing abnormal operation parameters with actual hash values not larger than a preset hash value from the abnormal operation parameter collection set, and reserving the abnormal operation parameters with actual hash values larger than the preset hash value from the abnormal operation parameter collection set to obtain a screened abnormal operation parameter collection set;
s306: acquiring investigation task information of the fishing vessel, determining investigation indexes based on the investigation task information, performing association degree calculation on each abnormal operation parameter in the investigation indexes and the screened abnormal operation parameter set by a gray association analysis method, and acquiring the abnormal operation parameters with association degree larger than a preset association degree;
s308: determining abnormal equipment which possibly affects the investigation task of the fishing vessel based on the abnormal operation parameters with the association degree larger than a preset association degree;
s310: inputting the abnormal equipment which possibly affects the investigation task of the fishing vessel into a Bayesian network for secondary simulation association to obtain the abnormal equipment which finally affects the investigation task of the fishing vessel, and marking the abnormal equipment which finally affects the investigation task of the fishing vessel as associated abnormal equipment output.
The performance information includes information on each equipment model in the fishing vessel, information on total operation time of the equipment, information on real-time evaluation report of the equipment, and the like. The investigation task information comprises a working path, a working precision grade, working time and the like of the investigation. After the abnormal operation parameters are determined, the abnormal operation parameters and equipment of the fishing vessel can be subjected to association analysis through the method, and the abnormal operation parameters which can influence the operation effect of the fishing vessel during operation are screened out by combining the performance information and investigation task information of the fishing vessel, so that the abnormal equipment which can influence the investigation effect of the fishing vessel is further determined, a corresponding regulation and control scheme is made according to the abnormal equipment, the operation investigation effect of the fishing vessel is further ensured, and reliable data is provided for the follow-up analysis of the fishery resource amount.
