Abstract
The invention relates to a module (100) which is attached to a trawl, and which at least comprises measuring sensors (330) and a power supply unit. (320) The sensors are basically inactive, but can be activated as the need arises to measure different parameters. In an embodiment the module also includes a power-generating movement device connected to a charging device that can supply energy to the power supply unit. The module may also include communication means. In an alternative embodiment the module ma include a trawl door that can drag the drawl in a desired direction. Several modules may be (combined to form a system that both measures different parameters and positions the trawl in order to achieve an optimal trawling process.
Claims13
A module (100) for monitoring and optimising a trawl operation where the module (100) is arranged for attachment to a line (420) connected to a trawl bag (410), and where the module (100) at least comprises a power supply unit (320), a plurality of measuring sensors (330), and
- communication means, characterised in that one or more of the measuring sensors (330) are arranged to be remotely activated by means of control signals.
A method for monitoring and optimising a trawl operation where one or more trawl bags (410) are dragged behind a trawler (400) via lines (420, 430), and where the method involves use of a module (100) arranged for attachment to the lines (420, 430), and where the module (100) at least comprises a power supply unit (320), a plurality of measuring sensors (330) and communication means,
- characterised in that the measuring sensors (330) are arranged to be remotely activated by means of control signals.
A system for monitoring and optimising a trawl operation where one or more trawl bags (410) are dragged behind a trawler (400) via lines (420, 430), and where the system includes at least two modules (100) which are attached to the lines (420, 430), and where the modules (100) at least comprise a power supply unit (320), a plurality of measuring sensors (330) and communication means,
- characterised in that the measuring sensors (330) are arranged to be remotely activated by means of control signals.
