Technical Field
The invention belongs to the technical field of culture equipment, relates to a sensor array, and particularly relates to a pull wire sensor array based on a fish ethology mode.
Background
How to automatically detect the hunger degree of fish and decide whether to feed (feed) or not is of great significance in aquaculture. China is a fishery big country, and in aquaculture, economic benefits and ecological benefits generated by aquaculture activities are often closely related to aquaculture modes. At present, fishermen usually judge the feeding amount and feeding time of feed according to own experience when feeding fish, and the mode has a plurality of problems: the fish food amount is not only related to the growth stage and the daily feeding period of the fish, but also related to the weather, the water temperature and the real-time state of the fish, so that the feeding amount and the feeding time cannot be accurately controlled, on one hand, fishermen do not know the accurate 'food amount' of the fish, but worry about that the fish is not full, so that the phenomenon of fish starvation is avoided, the feeding amount is not increased, and excessive feed is not eaten by fish flocks in water and sinks into the water bottom to be decomposed into nitrogen and phosphorus compounds, thereby polluting the water body.

Detailed Description
In order to facilitate the understanding and implementation of the present invention for those of ordinary skill in the art, the present invention is further described in detail with reference to the accompanying drawings and examples, it is to be understood that the embodiments described herein are merely illustrative and explanatory of the present invention and are not restrictive thereof.
Referring to fig. 1 and 2, the pull wire sensor array based on fish ethology model provided by the invention is arranged right below a feed machine; the device comprises an upper fixed frame 1, a lower fixed frame 2, a pull wire 3, a singlechip and a power module; the stay wires 3 are provided with a plurality of stay wires; the upper ends of the stay wires 3 are provided with fixed contacts 4, the fixed contacts 4 are connected to the upper fixed frame 1 through fixed springs 6, and the lower ends of the stay wires 3 are directly connected to the lower fixed frame 2; 2 detection sheets 5 which are vertical to the horizontal plane and are parallel to each other are arranged on the left side and the right side below the fixed contact 4, the outer surfaces of the detection sheets and the fixed contact are both made of metal and have conductivity, and the detection sheets and the fixed contact are both arranged above the water surface; the detection pieces 5 are all connected with the single chip microcomputer; the power supply module is connected with the singlechip and provides power for the singlechip; when no fish body touches, the fixed contact 4 is separated from the detection piece 5; when the fish body takes place the contact with acting as go-between, drive 3 movements of acting as go-between to the fixed contact 4 that the drive is connected on fixed spring 6 moves down, and with two detection piece 5 contacts of its below, fixed contact 4 has connected two detection piece 5 together, and this contact signal is caught by the singlechip, accomplishes the touching and detects, and when the fish body left, fixed spring 6 with fixed contact 4 is connected resets fixed contact 4, and fixed contact 4 separates with detection piece 5.
The diameter of the fixed contact 4 of the present embodiment is about 2cm, and 2 detection pieces 5 which are perpendicular to the horizontal plane and parallel to each other are arranged at the left and right sides of a position which is about 0.5-1cm away from the fixed contact 4, and the distance between the detection pieces is slightly smaller than the diameter of the fixed contact 4.
The stay wire 3 of the embodiment is mainly made of anticorrosive fibers, and the diameter of the stay wire is 1-3 mm; the density of the guy wire 3 is adjustable, and is generally 2 to 3 times longer than the width of adult fish; the upper and lower fixing frames 1 and 2 may be sized as desired. The upper fixing frame 1 is arranged in parallel at a position of 30cm above the water surface.
The sensor array of the invention judges the hunger degree of the fish by detecting the feeding behavior of the fish, thereby serving for designing an accurate feeding system of the fish, the basic principle is based on the feeding behavior mode of the fish, namely, a group of sensors are arranged in a water area of a certain range of a feed feeding area, when the feed feeding is started, the feed is put into the water body, at the moment, the fish is in the most hungry state, the movement of fish groups in the feeding area is fast and frequent, the movement is sensed by the mutual contact of the fish bodies and the sensors, the maximum movement frequency (Max _ F) is obtained, the sensors continuously monitor and record the movement frequency (F) of the fish, when the fish groups are 'full' after a certain time, the fish groups begin to leave the feeding area, the swimming speed of the fish bodies becomes slow, at the moment, the sensors can also sense the movement frequency (F-T) curve by drawing time, an F-T curve is formed which decreases progressively with feeding time, and by analysing the T-F curve, an empirical frequency inflection point (e.g. point in time T when F is 20% Max _ F) or a stable point in time T at which the fish is "fed" can be found.
Compared with the traditional mode, the method does not depend on environmental factors (such as water temperature and light rays), and accurately judges the time point of the fish school 'satiation' only through the behavior mode of the fish, so that an information source is provided for an accurate feeding system.
It should be understood that parts of the specification not set forth in detail are well within the prior art.
It should be understood that the above description of the preferred embodiments is given for clarity and not for any purpose of limitation, and that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
