Embodiment 1

[0035] The utility model relates to a cableless net position meter for small trawler fishing, which comprises a net class sensor, a net board sensor and a control terminal. The specific composition block diagram is as follows figure 1 shown.

[0036] The control terminal is arranged in the cockpit of the trawler. The control terminal includes communication components and processing equipment. The processing equipment communicates with the network sensor through the communication component, and receives and processes the data sent by the network sensor.

[0037] In this embodiment, the control terminal is composed of a communication component and a computer. The computer communicates with the network sensor through the communication component, and receives and processes the data sent by the network sensor; the display screen of the computer displays the data processed by the computer.

[0038] The stencil sensor is arranged at the trawling slat of the trawler, and is used to c...

Embodiment 2

[0042] Present embodiment is on the basis of embodiment 1, has the situation of left and right two stencils for the trawl net of fishing trawler, carries out following processing:

[0043] The left screen sensor and the right screen sensor are respectively arranged at the left and right screens;

[0044] When the cableless network position meter is working, the left and right screen sensors work together as figure 2 Shown: the underwater acoustic interrogation signal A is sent from the left screen sensor to the right screen sensor, figure 2 As shown in ①; the right screen sensor immediately transmits its measurement data to the left screen sensor after receiving the underwater acoustic inquiry signal A. figure 2 As shown in ②; after the left stencil sensor receives the measurement data of the right stencil sensor, it calculates the distance information between the left and right stencils according to the principle of acoustic response ranging, and then fuses the measuremen...

Abstract

The invention discloses a cableless net position meter for small trawler fishing, which comprises a mesh sensor, a net plate sensor and a control terminal; The equipment communicates with the mesh sensor through the communication component, receives and processes the data sent by the mesh sensor; the mesh sensor is arranged at the trawl mesh of the trawler to collect the state data of the mesh and send it through underwater acoustic communication. The network sensor is sent to the mesh sensor by means of the trawl mesh sensor; the mesh sensor is arranged at the trawl mesh of the trawler to collect the mesh state data and obtain the mesh state data of the mesh sensor; the mesh state data and the mesh state data are obtained by The grid sensor is transmitted to the control terminal together. The cableless network position meter is used to measure the working status of the stencil and the net, and the working status of the trawl net.

Description

technical field [0001] The invention belongs to the technical field of marine electronic equipment, and in particular relates to a cableless net position meter for small-sized trawler fishing. Background technique [0002] Most of the Chinese offshore fishermen's trawl fishing boats do not exceed 500 tons, which are small trawlers. At present, they still use the bottom trawling method. With the depletion of offshore fishery resources and the increasing emphasis on environmental protection, the variable water layer trawling operation will gradually replace the bottom trawling operation. In this way, the net position meter, which was not valued before, will become particularly important to improve fishing efficiency. At present, the existing cabled network position meters in foreign countries use multi-beam sonar as the basic working principle to monitor the fish schools around, in front of, and below the network port and the state of the network port. This kind of network po...
