Abstract

The invention discloses a sonar fish shoal detection system and method. The sonar fish shoal detection system comprises a central server and multiple detection floaters which are arranged on the water surface. Each detection floater comprises a shell, a processor, sonar sensing equipment, water temperature detection equipment and positioning equipment. The sonar sensing equipment detects fish shoal depth information of a water area in which the detection floaters are arranged. The water temperature detection equipment detects water surface temperature of the water area in which the detection floaters are arranged. The positioning equipment positions the positioning information of the floaters. The processor transmits the fish shoal depth information, the water surface temperature and the positioning information to the central server. The central server receives the fish shoal depth information, the water surface temperature and the positioning information transmitted by all the detection floaters and draws a fish shoal comprehensive information graph by using the fish shoal depth information, the water surface temperature and the positioning information of each detection floater so as to analyze the distribution position and depth of the fish shoal. The sonar fish shoal detection system has large scanning range so that the data requirements of wide-range fish shoal detection and fishery resource estimation can be met, data sharing of multiple ships can be realized and judgment and prediction of the movement direction of the fish shoal and tracking are facilitated.

Description

technical field [0001] The invention relates to a fish school detection system, in particular to a sonar fish school detection system. Background technique [0002] In the process of fishery production, fish detection is a prerequisite for fishery operations. For hundreds of years, humans have been exploring how to quickly and accurately find and track fish schools. However, the direction of action is often difficult to determine because fish colony behavior is disturbed by factors such as feeding conditions, water temperature, salinity, and interspecies competition. [0003] After the invention of sonar technology, it has been widely used in various fishing boats, and the output has also increased significantly. However, a single pair of sonar equipment has a small scanning range and cannot meet the data requirements for large-scale fish detection and fishery resource assessment. In addition, a single sonar data is not conducive to judging and predicting the direction of ...
