Embodiment 1

[0024] The present embodiment provides a method for collecting audio data of abalone activity, comprising 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 the underwater audio data and transmits it to the server through the gateway for saving.

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

[0028] The real-time collection and preservation of underwater audio and video data can provide a basis for researchers' follow-up research and verify each other, which can reduce the workload of researchers.

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

Embodiment 2

[0049] like Figure 1-2 As shown, this embodiment provides a device for collecting audio signals of abalone activity, which is composed of three parts: a device, a gateway and a server.

[0050] The device includes the following structures.

[0051] Dissolved oxygen sensor. The dissolved oxygen sensor measures the dissolved oxygen content in the water body by electrochemical means. 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] The dissolved oxygen data is used as a water quality indicator to feedback control the work of the aerator, so as to keep the dissolved oxygen in the environment where the abalone grows stable.

[0053]The aerator, when the aerator receives the control command, correspondingly, oxygenates the pool water, or stops running. The control commands include oxygen-increasing commands, stop commands, restriction commands, ...

Embodiment 3

[0069] After fasting a batch of abalone weighing about 50g for 3 days, select 5 with better vitality and move them into a small fish tank filled with seawater. The salinity of the seawater is 30‰ and the temperature is 20-24℃. Longxucai, the device described in the second embodiment is installed and adjusted in the fish tank, and the audio data of the abalone activity is continuously collected, and the collection time is 24 hours.

[0070] image 3 Time-frequency diagram of the audio signal of abalone feeding collected for a period of abalone without aerobic noise. The figure shows that the frequency distribution of abalone feeding audio signals is in the range of 3.6kHz-20kHz, 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 a method and device for collecting audio data of abalone activity, which comprises the following steps: collecting dissolved oxygen data of an abalone pond, storing and analyzing them, and increasing oxygen in the pond water when the dissolved oxygen data is lower than that required for abalone activities; collecting And save the underwater audio data; separate the abalone activity audio data. The invention realizes the accurate and effective collection of long-term abalone activity data, expands the depth of abalone research, and reduces the workload of scientific researchers.

Description

technical field [0001] The invention relates to the technical field of abalone culture, in particular to a method and device for collecting audio data of abalone activity. Background technique [0002] Abalone is a common aquaculture product. In recent years, with the improvement of residents' living standards, abalone has gradually appeared on the dining table of ordinary people. The market demand for abalone has increased year by year, and the scale of aquaculture has gradually expanded. The research on the physiological activities of abalone has never been stagnant by researchers. Through in-depth study of the physiological activities of abalone, it is possible to more accurately reveal the law of abalone's movement behavior and provide more effective guidance for abalone farming. At present, in the study of abalone movement behavior, researchers only focus on the movement trajectory of abalone, and the research on the acoustic field of abalone feeding and other activitie...
