Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to a channel catfish activity testing system and method. Background Art

[0002] In the breeding process of channel catfish, the activity of fish is an important indicator of its health status, the suitability of the growth environment and the potential disease risk. The traditional method of judging the activity of fish mainly relies on manual observation, which has the following shortcomings:

[0003] 1. Highly subjective: Different breeders may have different criteria for judging fish activity, resulting in inaccurate and inconsistent evaluation results.

[0004] 2. Inefficiency: Manual observation takes a lot of time and manpower, especially in large-scale farming. It is difficult to achieve real-time monitoring of all fish, and the recording and organization are cumbersome and error-prone.

[0005] 3. Incomplete information: Manual observation can only obtain limited surface information and cannot accurately quantify key parameters such as the intensity, frequency, and duration of fish activity, making it difficult to conduct in-depth analysis of the health status of fish.

[0006] Therefore, developing a system that can objectively, efficiently, comprehensively and accurately measure the activity of channel catfish is a technical problem that urgently needs to be solved in this field. Summary of the invention

[0007] The technical problem to be solved by the present invention is to propose a channel catfish activity testing system and method in view of the above-mentioned deficiencies in the prior art, which can automatically, accurately and comprehensively perform quantitative testing on the activity of channel catfish, provide a scientific decision-making basis for breeding personnel, timely discover fish health problems and environmental abnormalities, and improve breeding efficiency.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a channel catfish activity testing system, comprising a monitoring unit, a data processing unit, a control and display unit and a data storage and transmission unit, wherein the data processing unit performs comprehensive processing on the data monitored by the monitoring unit, the control and display unit controls and displays the monitoring unit and the data processing unit, and the data storage and transmission unit is used to store the data or analysis results of the monitoring unit and the data processing unit, and transmit them to a management platform or a mobile terminal.

[0009] Preferably, the monitoring unit includes an image acquisition module, an acoustic sensor module, and a water flow sensor module.

[0010] Preferably, the image acquisition module includes a plurality of high-definition underwater cameras, which are distributed at different positions and depths in the breeding pond, and can capture the moving images of the channel catfish in an all-round and non-dead angle manner. The camera has the characteristics of being waterproof and corrosion-resistant, and is equipped with an automatic cleaning device to prevent the lens from being blocked by algae, dirt, etc., to ensure the clarity of the image. The acoustic sensor module includes acoustic sensors installed on the wall and bottom of the breeding pond, which are used to detect the sound wave signals generated when the fish swims; these sensors can accurately sense sound waves of different frequencies and intensities, covering the entire water area of ​​the breeding pond. The water flow sensor module is installed at the water inlet and outlet of the breeding pond and at a position inside the pond to measure the speed, direction and changes of the water flow. Because the water flow has an important influence on the activity of fish, the relationship between the activity of fish and environmental factors can be more accurately analyzed by monitoring the water flow.

[0011] Preferably, the data processing unit includes an image analysis module, an acoustic signal processing module, a water flow data analysis module and a comprehensive evaluation module.

[0012] Preferably, the image analysis module receives the image data from the image acquisition module, analyzes the image, and identifies the individual profile, posture, motion trajectory, and other information of the channel catfish. By comparing and analyzing the continuous images, the parameters such as the swimming speed, acceleration, and turning frequency of the fish can be calculated, thereby quantifying the activity intensity of the fish.

[0013] Preferably, the acoustic signal processing module performs filtering, amplification, feature extraction, etc. on the sound wave signals collected by the acoustic sensor. According to the sound wave characteristics generated by the fish swimming, different behavior patterns are identified, such as normal swimming, rapid escape, foraging, etc., and the sound wave signals are converted into corresponding activity values.

[0014] Preferably, the water flow data analysis module analyzes the data collected by the water flow sensor and combines it with the fish activity data to determine the impact of the water flow on the activity of the fish. For example, if the water flow in a certain area is abnormal but the activity of the fish is significantly reduced, it may indicate that there is a water quality problem or fish discomfort in the area.

[0015] Preferably, the comprehensive evaluation module comprehensively processes the data obtained by the image analysis module, the acoustic signal processing module and the water flow data analysis module, evaluates the overall activity of the channel catfish, and outputs an activity score and a detailed analysis report, including the average activity intensity of the fish, the proportion of abnormal behaviors, the degree of influence of environmental factors, etc.

[0016] Preferably, the control and display unit includes a control module and a display module, wherein the control module is used to control the entire system, including setting monitoring parameters (such as monitoring frequency, image resolution, sensor sensitivity, etc.), starting and stopping monitoring, and remote control functions. It can communicate with external devices through a wired or wireless network to achieve remote operation.

[0017] Preferably, the display module displays the system's operating status, real-time activity data, historical data trend charts and other information in an intuitive graphical interface. Farmers can use the display module to keep track of the fish's activity at any time and detect abnormal changes in a timely manner. At the same time, the display module can also display alarm information. When the fish's activity exceeds the normal range or changes dramatically, the system automatically issues an alarm.

[0018] Further preferably, the data storage and transmission unit includes a data storage module and a data transmission module. The data storage module is equipped with a large-capacity storage device for storing the collected images, acoustic signals, water flow data, and processed analysis results. The stored data is classified and managed according to time, breeding pond number and other information, which is convenient for query and call; the data transmission module supports a variety of data transmission methods, such as Wi-Fi, Ethernet, 4G / 5G, etc., and transmits the collected data and analysis results to the breeding management platform or the breeding personnel's mobile terminal in real time, which is convenient for remote monitoring and data analysis.

[0019] Another technical solution of the present invention is a method for testing the activity of channel catfish, using the channel catfish activity testing system in the above technical solution, comprising the following steps:

[0020] S1. The image acquisition module, acoustic sensor module and water flow sensor module of the monitoring unit respectively collect channel catfish image data, acoustic wave signals and water flow data;

[0021] S2. The image analysis module of the data processing unit analyzes the swimming speed, acceleration, turning frequency and other parameters of the channel catfish, the acoustic signal processing module converts the sound wave signal into the corresponding activity value, the water flow data analysis module analyzes the impact of water flow interruption on the activity of the fish; and the comprehensive evaluation module

[0022] S3. Evaluate the overall activity of channel catfish and output an activity score and a detailed analysis report, including the average activity intensity of the fish, the proportion of abnormal behaviors, the degree of influence of environmental factors, etc.;

[0023] S4. The control module of the control and display unit communicates with external devices through a wired or wireless network to achieve remote operation; the display module keeps track of the activity of the fish and promptly detects abnormal changes. At the same time, the display module displays an alarm message. When the activity of the fish exceeds the normal range or changes dramatically, the system automatically issues an alarm;

[0024] S5. The data storage module of the data storage and transmission unit stores data in a classified manner according to time, breeding pond number and other information for easy query and call; the data transmission module transmits the collected data and analysis results to the breeding management platform or the mobile terminal of the breeding staff in real time.

[0025] Compared with the prior art, the present invention achieves the following technical effects:

[0026] 1. Improve assessment accuracy:

[0027] By collecting data through a variety of sensors, the subjectivity and limitations of traditional manual observation can be overcome, and the activity of channel catfish can be more accurately assessed, providing a reliable basis for evaluating the health status and growth environment of fish.

[0028] 2. Realize real-time monitoring:

[0029] The system can continuously and automatically monitor the fish in the breeding pond without human intervention. Breeders can obtain real-time information on the activity of the fish, identify potential problems in a timely manner, and take appropriate measures to improve breeding efficiency and fish survival rates.

[0030] 3. Comprehensive analysis of fish behavior and environmental factors:

[0034] For ease of explanation, the present invention is described in detail with reference to the following specific embodiments and the accompanying drawings.

[0035] Figure 1 It is a schematic diagram of the overall process framework of the system of the present invention. DETAILED DESCRIPTION

[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments; in the following description, specific details such as specific configurations are provided only to help fully understand the embodiments of the present invention. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0038] Example 1 System Installation and Initialization

[0039] After the construction of the breeding pond is completed, the installation location and quantity of each sensor (HD underwater camera, acoustic sensor, water flow sensor) in the monitoring unit are determined according to the size, shape and depth of the breeding pond. Ensure that the camera can cover the entire water area of ​​the breeding pond, and the acoustic sensor and water flow sensor are reasonably distributed to obtain comprehensive and accurate data.

[0040] After the installation is completed, connect each sensor to the data processing unit, control and display unit, data storage and transmission unit, and perform system wiring and network configuration to ensure normal communication between each unit.

[0041] Start the system and set monitoring parameters in the control module, such as the resolution of image acquisition (which can be set to an appropriate value according to the size of the breeding pond and the size of the fish, such as 1080p or higher), the acquisition frequency (acquiring an image every 5 minutes, etc.), the sensitivity of the acoustic sensor (adjusted according to the intensity range of the sound waves generated by the fish swimming), the measurement accuracy of the water flow sensor, etc. At the same time, set the path and format of data storage, as well as the target address of data transmission (the IP address of the breeding management platform or the mobile terminal of the breeding personnel, etc.).

[0042] Example 2 Data Collection and Processing Process

[0043] Image acquisition: The high-definition underwater camera collects the activity images of channel catfish in the breeding pond at a set frequency, and transmits the image data to the image analysis module in real time.

[0044] Acoustic signal acquisition: The acoustic sensor continuously monitors the sound wave signals generated by the swimming fish, and after pre-processing such as amplification and filtering, the signal is transmitted to the acoustic signal processing module.

[0045] Water flow data collection: The water flow sensor measures the speed, direction and other parameters of the water flow in the breeding pond, and sends the data to the water flow data analysis module.

[0046] Image analysis: After receiving the image data, the image analysis module uses a deep learning-based image recognition algorithm (such as a convolutional neural network) to identify individual fish, and calculates the fish's swimming speed, acceleration, steering angle and other motion parameters by tracking the changes in the fish's outline in continuous images. For example, the swimming speed is obtained by calculating the change in the position of the fish in two adjacent frames and dividing it by the time interval; the steering situation is determined by analyzing the change in the curvature of the fish's motion trajectory.

[0047] Acoustic signal processing: The acoustic signal processing module extracts features from the collected sound wave signals and identifies the sound wave features corresponding to different behavior patterns. For example, the frequency and intensity of the sound waves are relatively stable during normal swimming, while the frequency and intensity of the sound waves increase sharply during rapid escape. Based on these features, the sound wave signals are converted into activity values.

[0048] Water flow data analysis: The water flow data analysis module analyzes water flow data to determine the impact of water flow on fish activity. If a sudden change in water flow speed in a certain area is found and the activity of fish decreases, it may indicate that there is a water quality problem in the area or that the fish are being adversely stimulated.

[0049] Comprehensive evaluation: The comprehensive evaluation module combines the results of image analysis, acoustic signal processing and water flow data analysis. For example, the fish's swimming speed, behavioral pattern activity, environmental influencing factors and other factors are combined by weighted average to obtain an overall activity score. The score range can be set from 0-100, where 0 means that the fish is extremely inactive and may have serious problems, and 100 means that the fish is very active and healthy. At the same time, a detailed analysis report is generated, including information such as the average activity intensity of the fish, the proportion of different behavioral patterns, and the degree of influence of water flow on activity.

[0050] Example 3 Display and alarm

[0051] Display: The display module of the control and display unit displays the system's operating status, current activity score, activity data trend chart and other information in real time. Farmers can intuitively understand the changes in fish activity through the graphical interface. For example, the changes in fish activity scores over the past 24 hours are displayed in the form of a line graph, which is convenient for farmers to observe the fluctuation trend of activity.

[0052] Alarm: When the fish activity score exceeds the normal range (such as less than 30 or more than 90) or the activity change rate exceeds the set threshold (such as the activity change per minute exceeds 10 points), the system automatically triggers an alarm. The alarm information can be sent to the breeders through sound, SMS, push notifications, etc., reminding them to check the fish in time and take appropriate measures, such as checking the water quality and whether the fish are sick.

[0053] Example 4 Data Storage and Management

[0054] Data storage: The data storage module stores the collected raw data (images, acoustic signals, water flow data) and processed analysis results (activity scores, analysis reports) in a local hard disk or network storage device in chronological order and by aquaculture pool number. To facilitate query and management, data storage uses a database management system to annotate each data file in detail, including information such as collection time, aquaculture pool location, and data type.

[0055] Data backup and recovery: To prevent data loss, the system regularly backs up stored data, which can be backed up to an external hard drive, cloud storage, etc. When the system fails or data is damaged, it can be restored through the backup data to ensure data integrity and reliability.

[0056] Example 5 Remote Monitoring and Management

[0057] Remote connection: Through the data transmission module, farmers can use mobile terminals (such as mobile phones, tablets) or software on the farming management platform to connect to the system through the network (such as Wi-Fi, 4G / 5G). After entering the correct username and password on the remote device, you can log in to the system for remote monitoring and management.

[0058] Remote operation and viewing: On the remote terminal, farmers can view the same information as the local display module, including real-time activity data, historical data trend charts, alarm information, etc. At the same time, the monitoring parameters of the system can be adjusted through the remote control module, such as modifying the image acquisition frequency, sensor sensitivity, etc., to achieve remote management.
