Embodiment 1

[0024]This embodiment provides a method for collecting audio data of abalone activities, including the following steps:

[0025]The dissolved oxygen sensor collects the dissolved oxygen data of the abalone pond and transmits it to the server through the gateway for storage. Among them, the gateway uploads dissolved oxygen data every 60s.

[0026]The underwater microphone collects underwater audio data and transmits it to the server through the gateway for storage.

[0027]The infrared camera collects underwater video data and transmits it to the server through the gateway for storage.

[0028]The real-time collection and storage of underwater audio and video data can provide scientific research personnel with a basis for subsequent research, and mutual confirmation can reduce the workload of scientific researchers.

[0029]The server processes underwater video data in real time. When it detects that the abalone is moving, the server issues a restriction instruction to the gateway. After the gatewa...

Embodiment 2

[0049]Such asFigure 1-2As shown, this embodiment provides an abalone activity audio signal collection device, which is composed of three parts: a device, a gateway, and a server.

[0050]The equipment includes the following structure.

[0051]Dissolved oxygen sensor. The dissolved oxygen sensor measures the dissolved oxygen content in the water by electrochemical methods. The sensor has a built-in AD analog-to-digital conversion module, and the converted dissolved oxygen digital signal is transmitted to the gateway in the RS485 protocol format.

[0052]Dissolved oxygen data is used as a water quality indicator to feedback and control the operation of the aerator, so as to keep the dissolved oxygen stable in the water environment where the abalone grows.

[0053]The aerator, when the aerator receives a control command, it will perform aeration on the pool water or stop running accordingly. Control commands include oxygen increase commands, stop commands, limit commands, and limit lift commands.

Embodiment 3

[0069]After fasting a batch of abalone weighing about 50g for 3 days, select 5 more vigorous abalones and move them into a small fish tank filled with sea water. The salinity of the sea water is 30‰ and the temperature is 20-24℃. Fresh fish are provided in the fish tank. Asparagus, the device described in the second embodiment is installed and adjusted in the fish tank to continuously collect the abalone activity audio data, and the collection time is 24 hours.

[0070]image 3 The time-frequency diagram of the collected audio signal of abalone without aeration noise. The figure shows that the frequency of the abalone feeding audio signal is distributed in the range of 3.6kHz-20kHz, and the duration of each signal is between 300-400ms, and the shortest time interval between adjacent signals is 1.5s. This embodiment verifies the reliability and effectiveness of the present invention.

Abstract

The invention discloses an abalone activity audio data acquisition method and device. The method comprises the following steps that dissolved oxygen data of an abalone pool are collected and are stored and analyzed, and when the dissolved oxygen data are lower than the demands of abalone activities, oxygenation is carried out on pool water; underwater audio data are collected and stored; and abalone activity audio data are separated out. By means of the method and device, long-time accurate and effective acquisition of abalone activity data is realized, the abalone research depth is increased,and the workload of researchers is reduced.

Description

Technical field[0001]The invention relates to the technical field of abalone breeding, in particular to a method and device for collecting audio data of abalone activities.Background technique[0002]Abalone is a common aquaculture product. In recent years, with the improvement of residents' living standards, abalone has gradually appeared on ordinary people's tables. The market demand for abalone has increased year by year, and the scale of aquaculture has gradually expanded. Researchers have never stopped studying the physiological activities of abalones. Through in-depth study of the physiological activities of abalones, they can more accurately reveal the laws of abalone exercise behavior and provide more effective guidance for abalone breeding. At present, in the study of abalone motion behavior, researchers only focus on the abalone's motion trajectory and other aspects, and the acoustic field of abalone feeding and other activities is still relatively simple. By studying the ac...
