Farmed fish intake information detector with MEMS acceleration sensors

Abstract

The invention relates to a farmed fish intake information sensing detection device for aquaculture, and especially relates to a farmed fish intake information detector adopting MEMS acceleration sensors. The detector is composed of a plurality of probes T1-Tn, a signal cable bus 8 connected with the probes T1-Tn, and the like. Each probe Tn is composed of a MEMS acceleration sensor 2, a microprocessor unit 3 and the like which are inside the probe and are welded on the same circuit board. The sensing detection device is suitable for various water bodies, and can provide information such as feeding fish population size and intake intensity for a microcomputer main controller 9 of a feeding machine.

Description

technical field [0001] The invention belongs to a sensor detection device for feeding information of farmed fish used in the aquaculture industry, in particular to a detector for feeding information of farmed fish using a "MEMS acceleration sensor". Background technique [0002] At present, most of the automatic feeding equipment used in the domestic intensive aquaculture industry is non-monitoring and feedback equipment, which can only be fed at a certain time interval according to the pre-programmed program or the set mechanical state. The biggest problem is that it can only be fed at a constant speed without manual control, and the feeding range and feeding speed cannot be adjusted according to the feeding situation of the fish. The external conditions (such as dissolved oxygen, water temperature, water quality, etc.) will change, especially in the case of inland large water surface farming. If these factors are not considered, then feeding too fast will cause part of the...

Problems solved by technology

[0006] The basic principles of the above foreign detection and feedback devices are similar, but they are all based on the premise of constant feeding speed. One is that the speed of fish competition slows down, and part of the feed is too late to be eaten by fish and begins to sink to the bottom as the fish are full. The second is marked by the fish school sinking from the water surface to the bottom of the cage, and when the fish school sinks from the water surface, it often means that the feeding speed is higher than the fish's competition speed, so there will be certain Feed waste to a certain extent, high device cost and only suitable for small volumes such as cages, not suitable for large water surface farming
