Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples are used for the present invention is described, but can not be used for limiting the scope of the invention.
Basic principle of the present invention is the reflection sounding principle, and with light wave, electromagnetic wave phase ratio, sound wave is little in the water transmission loss, and propagation distance is far away, is the best means of underwater small target detection and identification.During reflection sounding, transducer converts electronic signal to sound wave pulse and is transmitted in water, when sound wave runs into barrier in the water transmission process, different due to the specific acoustic impedance of object and aqueous medium, this object can produce scattering and reflex to incident acoustic wave, the backscattering of part voice signal is to the split beam transducer, if signal level surpasses the threshold value that the user selects, can be received and be converted into electronic signal and transfer to signal acquisition process and control module by the split beam transducer, generate reflectogram.The spread speed (1500m/s, under standard conditions) in water according to the interval time of receiving the target echo signal after acoustic emission and sound wave, can record the residing position of target, and echo signal power and structure are analyzed, and can estimate target strength.Compare simple beam or multiple-beam array, utilize the split beam technology can determine the position of target in wave beam, and according to the directive property of wave beam, the echo signal that departs from acoustic axis is compensated, thereby realizing the objective estimation to the fish target strength, measurement result is more accurate.
Target strength is an important parameter of marine acoustics assessment, and it is the parameter of a tolerance target object acoustic reflection performance, comparatively approaching with reflectance factor on its physical significance.The definition of target strength is the acoustic centres 1m place at distance objective, and the ratio of incidence sound intensity levels on the sound intensity reflected by target and same direction is multiplied by 10 after getting denary logarithm again.Target strength (TS) is expressed as:
TS=10×lg(Ir/Ii)=20×lg(Pr/Pi) （1）
(1) in formula, Ir, Ii are the reflection sound intensity and incidence sound intensity levels, and Pr, Pi are reflecting acoustic pressure and incident sound pressure.Had afterwards the scholar again target strength to be defined as:
TS=20×lg(σ/4π) （2）
(2) in formula, TS means target strength (dB), and σ means the marine acoustics cross section (m of target object
2).σ can be regarded as target object and incidence wave is produced to the acoustics equivalent area of scattering.
Under certain frequency of sound wave, for fish of the same race, the target strength of wall scroll fish and its body live forever at certain corresponding relation, and fish of the same race are in the situation that body appearance etc., and weight also about equally.Therefore can find the target strength weight single with it of fish and the relation of gross weight with this corresponding relation.
Fig. 1 shows a kind of according to an embodiment of the invention control system of throwing something and feeding for fish culture, and this system comprises: signal acquisition process and control module 4, the unit 3 of throwing something and feeding, rotary unit 2, split beam transducer 1.
Split beam transducer 1, be placed in water, is fixed in rotary unit 2, with signal acquisition process and control module 4, is connected.Compare simple beam or multiple-beam array, utilize the split beam technology can determine the position of target in wave beam, and according to the directive property of wave beam, the echo signal that departs from acoustic axis is compensated, thereby realizing the objective estimation to the fish target strength, measurement result is more accurate.
