Detection early-warning positioning buoy for electric fishing device

Abstract

The invention discloses a detection early-warning positioning buoy for an electric fishing device, and belongs to the technical field of fishery administration monitoring. The detection early-warningpositioning buoy comprises a buoy body, an instrument cabin, a battery cabin, an antenna, an electrode support, a copper sulfate electrode pair, an anchor chain and an anchor, the instrument cabin isused for installing a central processing unit, a GPS / BD positioning module and a 4G communication module, and the central processing unit processes electric field signals and calculates the orientation of the electric fishing device; the GPS / BD positioning module measures the position of the buoy; the 4G communication module transmits information; the antenna is located above the instrument cabinand provides signals for the 4G communication module; and the buoy body is located below the instrument cabin and provides positive buoyancy for the buoy. The battery cabin is positioned below the buoy body and used for supplying power and playing a counterweight role; the electrode support is positioned at the bottom of the battery cabin for mounting a copper sulfate electrode pair; the copper sulfate electrode pair measures an electric field signal sent by the electric fishing device; and the anchor chain is connected with the upper part and the lower anchor of the buoy. The positions of thebuoy and the electric fishing device are accurately measured to ensure that the fishery administration law enforcement ship obtains real-time data.

Description

Technical field [0001] The invention belongs to the technical field of fishery administration monitoring, and specifically relates to a detection and early warning positioning buoy for an electric fish device. Background technique [0002] The fishing device is an illegal fishing device. During the operation of the electric fish device, all fish species and sizes are culled without distinction. It can cause devastating damage to the fishery, and accidentally injure people, livestock, and poultry in the water, endangering public safety. Electric fish will reduce the number of many precious fish species. The instant electricity released by the electric fish device can power down a cow. Small fishes are usually electrocuted on the spot. If the large fishes survived by the stun, most of them lose their reproduction. Ability, will also cause devastating damage to snails and shellfish tadpoles that grow in the water. Especially in the season of fish reproduction, electric fish will ...

Problems solved by technology

The main disadvantages of this device are: (1) The 4G module antenna is placed in water. Due to the existence of the electromagnetic wave skin effect, the 4G frequency band (1880~2655MHz) signal cannot communicate in water, which is not conducive to the communication of the 4G module; (2) Even if the 4G module antenna is extended out of the water, it can only ensure that it can communicate when it is deployed. When the water level rises due to precipitation or other reasons, the water surface will still submerge the 4G antenna, resulting in communication failure; (3) The current sensor uses a DC transformer Or the linear Hall current sensor, which is a scalar device, can only measure the signal size, but cannot realize the directional measurement of the signal; (4) The power supply uses 18650 batteries, the power is limited, and the power cannot be replenished. When the battery power is exhausted, the whole system will Discarded; (5) Without a positioning module, it cannot locate itself, and even if the target is found, it cannot instruct law enforcement personnel to rush to the scene for disposal
