Description

Technical Field

[0001] The present invention relates to the field of aquatic product safety monitoring and early warning, and in particular to an aquatic product safety monitoring and early warning system and method. Background Art

[0002] With the development of society, the demand for factory-based high-density aquaculture has increased with the increase in people's demand for aquatic products. Factory-based high-density aquaculture has gradually become an important breeding method. However, during the breeding process, water quality deterioration, diseases and other problems will lead to a decline in breeding benefits, so real-time monitoring and early warning are needed. Deficiencies of the existing monitoring and early warning system The current monitoring and early warning system has problems such as incomplete data collection and low accuracy. It cannot fully consider the correlation of monitoring variables, which affects the early warning effect. Aquatic product quality and safety issues There are unsafe factors such as epidemics, excessive additives, retention of harmful substances and microorganisms in the aquatic product supply chain. It is necessary to build an effective early warning indicator system to reduce risks.

[0003] Now, the present invention provides the possibility for aquatic product traceability and safety early warning, and data can be collected and transmitted in real time through sensors and other equipment. The importance of water quality monitoring, water quality is a key factor affecting the growth and quality of aquatic products, and it is necessary to monitor the water quality at a high frequency or even in real time, and adjust it according to the monitoring results to reduce the losses caused by water quality deterioration. The development of these background technologies provides the basis and motivation for the research and development of aquatic product safety monitoring and early warning systems, aiming to improve the quality and safety of aquatic products and protect the health of consumers. Summary of the invention

[0004] In order to solve the technical problems raised by the above background technology, the present invention is proposed. The embodiments of the present invention provide a system and method for monitoring and early warning of aquatic product safety.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] In a first aspect, the present invention provides an aquatic product safety monitoring and early warning system, comprising:

[0007] The data acquisition module collects relevant data in the production, processing, storage, and transportation of aquatic products in real time, including but not limited to water quality parameters, temperature, and humidity. The specific acquisition process is as follows:

[0008] By using biosensors to detect the aquaculture water quality in different areas at different times, the aquaculture water quality parameters of each detection point in each area can be obtained, including but not limited to dissolved oxygen content, various microorganisms, pH and ammonia nitrogen content. Inappropriate pH will affect the physiological function and growth and development of aquatic products; it is essential for the survival of aquatic organisms, and too low pH will cause hypoxia in fish and other organisms.

[0009] By using temperature sensors to detect the aquaculture water temperature at different times and in different areas, and obtaining the temperature parameters of each area at each detection time point, we can know whether the water temperature is within the range suitable for the growth of aquatic products. Fish may have a specific optimal water temperature range, and deviation from this range may affect their growth rate, feeding enthusiasm and even health. Abnormal fluctuations in water temperature, sudden temperature rise or fall can be detected in time. By using humidity sensors to detect the aquaculture environment at different times and in different areas, the aquaculture humidity environment at each detection time point in each area can be obtained. Inappropriate air humidity may affect the survival and growth of aquatic products. Determine the humidity level of the aquaculture environment. Too high or too low humidity may cause some problems. High humidity may cause the growth of pathogens, and low humidity may make the surface of aquatic products dry and uncomfortable.

[0010] Through high-definition cameras, the survival status of aquatic products at each stage of production, transportation, storage and processing can be obtained. In the production stage, the growth status, activity status, health status, etc. of aquatic products in the breeding pond can be monitored in real time, abnormalities can be found in time and measures can be taken. At the same time, the breeding environment, such as water quality and water temperature, can be monitored. In the transportation stage, high-definition cameras can record the status of aquatic products during transportation to ensure that the transportation conditions are suitable, such as temperature and humidity, etc., to prevent damage or death during transportation. In the storage stage, the storage environment and aquatic products are continuously monitored to ensure that the storage conditions meet the requirements and avoid deterioration and other problems. In the processing stage, it can supervise whether the processing process is standardized, ensure compliance with hygiene standards and quality requirements, and effectively supervise the workers' operations.

[0011] Data transmission module: The collected data is accurately and timely transmitted to the database. The specific acquisition process is as follows:

[0012] All kinds of aquatic product data collected by sensors and detection equipment are sent to the information management module. During the data transmission process, a series of measures will be taken to ensure the accuracy of the data. The data is checked, and the transmitted data is verified and corrected to ensure that the data is not damaged or tampered with during the transmission process. At the same time, the transmission module will set the appropriate transmission frequency and priority to ensure that key data can be delivered quickly and preferentially. In addition, in order to cope with possible network failures or interruptions, the transmission module will also have a data caching function, and automatically resend the cached data after the network is restored to ensure the integrity of the data. The data transmission module works closely with other modules, so that the entire aquatic product safety monitoring and early warning system can operate efficiently and stably, providing strong protection for aquatic product safety.

[0013] The data analysis module analyzes the data obtained by sensors and equipment to evaluate the safety status and potential risks of aquatic products. The specific acquisition methods are as follows:

[0014] By obtaining the water quality parameters at each monitoring time point in each region, the reference water quality parameter interval at each monitoring time point in each region is obtained from the database, marked as the standard water quality parameter interval, and the actual water quality parameters are compared with the standard water quality parameter interval. If the actual water quality parameters are greater than or less than the standard water quality parameters, the actual water quality parameters are judged to be unqualified. If the actual water quality parameters are within the standard water quality interval, they are judged to be qualified. When the actual water quality parameters at each monitoring point in each region exceed the standard water quality interval, the processing and display terminal immediately sends information to the mobile phone terminal of the staff for the area exceeding the standard water quality interval, so that they can know the situation in time to ensure the sustainability of breeding and the quality and safety of aquatic products. Cluster analysis can be used to classify aquatic product data from different regions or batches, and the unqualified water quality parameter areas can be classified into one category for later observation.

[0015] By obtaining the water temperature at each monitoring time point in each area, the water temperature threshold interval at each monitoring time point in each area is obtained from the database, and the actual water temperature is compared with the reference water temperature threshold. If the actual water temperature is greater than or less than the reference water temperature threshold interval, it is judged as unqualified. If the actual water temperature is within the reference water temperature threshold interval, it is judged as qualified. The water temperature index is measured by data to be higher or lower than the set corresponding threshold interval. When the sensor receives that the aquaculture water temperature is higher or lower than the threshold interval, the early warning processing module sends a command to the control terminal display to control the chiller to cool the aquaculture area;

[0016] By obtaining the actual humidity parameters of each area at each monitoring time point, the humidity threshold interval of each area at each monitoring time point is obtained from the database, and the actual humidity parameters are compared with the reference humidity threshold. If the actual humidity parameter is greater than or less than the reference humidity threshold interval, it is judged as unqualified. If the actual humidity is within the reference humidity threshold interval, it is judged as qualified.

[0017] The actual environmental parameters of the breeding area are composed of the water quality parameters at each monitoring point in time in each area, the water temperature parameters at each monitoring point in time in each area, and the humidity parameters at each monitoring point in time in each area.

[0018] By analyzing the aquatic products at each monitoring time point, the survival status of aquatic products at each stage can be obtained. The survival status of aquatic products during production, transportation, storage and processing can be analyzed to obtain the suitable environment for aquatic products and reduce the loss rate at each stage.

[0019] The early warning processing module sends out early warning signals of different levels when the data analysis results show that there are potential safety hazards or exceed the set standards, so that the equipment and relevant personnel can take timely measures. The specific acquisition methods are as follows:

[0020] Through cluster analysis, we obtain the unqualified water quality parameter areas, which are divided into three different stages for processing. The pollution is received by the biosensor in the initial stage, transmitted to the early warning device and then sent to the maintenance personnel's mobile terminal. The maintenance personnel adjust the water exchange device for the water quality pollution area in the initial stage. Since high temperature operation during the day is easy to produce emergency response to aquatic organisms, the water exchange frequency should be updated to once every two days at night, and the water exchange volume should be controlled at 30% of the total water volume. In the development stage, the water exchange frequency is increased to once a day and the water exchange volume is controlled at 60% of the total water volume, and the pollutants are physically adsorbed. Severe stage: suspend aquaculture activities to avoid further losses, update the water exchange frequency to twice a day, control the water exchange volume to 100% of the total water volume, comprehensively investigate the pollution source, and properly handle the affected aquatic products, and open up new areas for transfer.

[0021] Depending on the degree of pollution, the amount of feed fed can also be controlled to ensure that the feed and medicine are qualified. The amount of feed can be reduced when the temperature is high or low to prevent the remaining feed from dissolving in the water and further polluting the water quality.

[0022] When the water temperature is too high, an alarm signal is issued through the data analysis module, and the alarm signal is transmitted to the chiller control terminal. The water temperature is cooled by the chiller control terminal to achieve temperature control, and the threshold value of the water temperature is exceeded or lowered for classification. Specifically, the temperature state corresponding to the current monitoring period is normal and marked as a normal temperature interval. Then, an instruction is issued to the chiller to not start. If the aquaculture water temperature is one to five degrees higher than the set standard water temperature interval, it is marked as an abnormal temperature interval, and an instruction is issued to the chiller control terminal to start a chiller device, set the cooling time to ten minutes, and the temperature to twenty degrees. If the equipment temperature is five to ten degrees higher than the set standard equipment temperature interval, it is marked as an abnormal temperature rise interval, and an instruction is issued to the chiller terminal to start two chillers, set the cooling time to twenty minutes, and the temperature to fifteen degrees. If the aquaculture water temperature is ten to fifteen degrees higher than the set standard water temperature interval, it is marked as a high temperature interval, and three chillers are turned on, and the cooling time is set to thirty minutes and the temperature is ten degrees.

[0023] The actual humidity parameters are obtained by analyzing the ambient humidity, and the early warning system then processes the humidity environment of the breeding area at each time and in each area. The early warning system sends a signal to the processing and display terminal, and turns on a ventilation device during the day to enhance air circulation. The device regulates the humidity and discharges the air humidity as quickly as possible. At night, the processing and display terminal turns on two ventilation devices to regulate the humidity of the breeding environment.

[0024] Through the monitoring terminal, we can always pay attention to the production, transportation, storage and processing of aquatic products, and prevent the loss of aquatic products in advance through the early warning system.

[0025] The information management module effectively manages and stores various types of data, facilitating query and traceability, and generates relevant reports to provide a basis for decision-making.

[0026] The information management module will classify and store the water quality parameters, water temperature parameters and humidity parameters in the aquaculture process. Relevant reports are automatically generated according to the templates and rules set in the database. These reports can include aquaculture production reports, water quality monitoring reports, cost-benefit analysis reports, etc. Decision makers can formulate aquaculture strategies, adjust resource allocation, optimize management processes, etc. based on these reports, thereby improving the efficiency and competitiveness of the entire aquaculture business. The data acquisition module and analysis module have data backup and recovery functions to cope with possible data loss risks.

[0027] In a second aspect, the present invention provides a method for monitoring and early warning of aquatic product safety, comprising the following steps:

[0028] A1. Real-time collection of relevant data in the production, processing, storage and transportation of aquatic products; including water quality parameters, temperature and humidity to obtain the corresponding parameters of the breeding environment;

[0029] A2. By obtaining the water quality parameters at each monitoring time point in each area, the percentage of chemical residues can be obtained from the water quality parameters, and the corresponding reference evaluation value interval of the chemical residue percentage can be obtained from the database. The chemical residue percentage value is compared with the evaluation value interval. If the chemical residue percentage value is not in the evaluation value interval, it is judged as unqualified, otherwise it is judged as qualified. When the actual water quality parameters at each monitoring point in each area at each time exceed the standard water quality interval, the processing display terminal immediately sends information to the staff's mobile phone terminal for the area that exceeds the standard water quality interval. By obtaining the water temperature at each monitoring time point in each area, the water temperature threshold interval at each monitoring time point in each area is obtained from the database, and the actual water temperature is compared with the reference water temperature threshold. If the actual water temperature is greater than or less than the reference water temperature threshold interval, it is judged as unqualified, and if the actual water temperature is within the reference water temperature threshold interval, it is judged as qualified. The water temperature index is measured by data to be higher or lower than the corresponding threshold interval. When the sensor receives that the aquaculture water temperature is higher or lower than the threshold interval, the early warning processing module sends a command to the control terminal display to control the chiller to cool the aquaculture area. By obtaining the actual humidity parameters of each area at each monitoring time point, the humidity threshold interval of each area at each monitoring time point is obtained from the database, and the actual humidity parameters are compared with the reference humidity threshold. If the actual humidity parameter is greater than or less than the reference humidity threshold interval, it is judged as unqualified. If the actual humidity is within the reference humidity threshold interval, it is judged as qualified. The water quality parameters at each monitoring time point in each area, the water temperature parameters at each monitoring time point in each area, and the humidity parameters at each monitoring time point in each area constitute the actual environmental parameters of the aquaculture area. The survival status of aquatic products at each stage is obtained by analyzing the survival status of aquatic products in production, transportation, storage and processing, and the suitable environment of aquatic products can be analyzed to reduce the loss rate at each stage.

[0030] A3. When the data analysis results show that there are safety hazards or exceed the set standards, different levels of early warning signals are issued so that the equipment and relevant personnel can take timely measures. The specific acquisition methods are as follows: the unqualified water quality parameter areas are divided into three different stages for processing. The biosensor receives the pollution in the initial stage, transmits it to the early warning device and then sends the command information to the maintenance personnel's mobile terminal. The maintenance personnel adjust the water exchange device for the water quality pollution area in the initial stage, and update the water exchange frequency to once every two days, and the water exchange volume is 30% of the total water volume. In the development stage, the water exchange frequency is increased to once a day, and the water exchange volume is controlled at 60% of the total water volume. In the serious stage: update the water exchange frequency to twice a day, and control the water exchange volume to 100% of the total water volume. Comprehensive investigation Pollution source, and properly handle the affected aquatic products, open up new areas for transfer, when the water temperature is too high, send an alarm signal to the chiller control terminal, the chiller control terminal cools the water temperature, and classifies the water temperature above the threshold. Specifically, the temperature state corresponding to the current monitoring period is normal, and the chiller is instructed to not start. If the water temperature is higher than the set water temperature range by one to five degrees, it is marked as an abnormal temperature range, and an instruction is sent to the chiller control terminal to start a chiller device, set the time to ten minutes, and the temperature is twenty degrees. If the temperature is higher than the set standard equipment temperature range by five to ten degrees, a command is issued to the chiller terminal to start two chillers, and the time is set to twenty minutes and the temperature is fifteen degrees.

[0031] A4. For water quality parameters, water temperature parameters and humidity parameters in the aquaculture process, information management will classify and store them, and automatically generate relevant reports based on the templates and rules set in the database. These reports may include aquaculture production reports, water quality monitoring reports, and cost-benefit analysis reports.

[0032] Compared with the prior art, the beneficial effects of the present invention are: it can monitor various key indicators of aquatic product quality and safety in real time and accurately, greatly reducing safety risks and ensuring the quality of aquatic products from production to consumption. It can timely discover potential harmful factors, such as excessive chemical residues and deterioration of water quality, so as to facilitate the adoption of targeted measures to solve them and prevent the expansion of problems.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present invention.

[0037] See also Figure 1 As shown, the present invention provides a water product safety monitoring and early warning system including: a data acquisition module, a data transmission module, a data analysis and processing module, an early warning processing module, an information management module, and a visual display module.

[0038] The data acquisition module is used to collect relevant data in the production, processing, storage, and transportation of aquatic products in real time, including but not limited to water quality parameters, temperature, humidity, and chemical residues. The specific acquisition process is as follows:

[0039] By using biosensors to detect the aquaculture water quality in different areas at different times, the aquaculture water quality parameters of each detection point in each area can be obtained, including but not limited to dissolved oxygen content, various microorganisms, pH and ammonia nitrogen content. Inappropriate pH will affect the physiological function and growth and development of aquatic products; it is essential for the survival of aquatic organisms, and too low pH will cause hypoxia in fish and other organisms.

[0040] By using temperature sensors to detect the aquaculture water temperature at different times and in different areas, and obtaining the temperature parameters of each area and each detection time point, we can know whether the water temperature is within the range suitable for the growth of aquatic products. For example, some fish may have a specific optimal water temperature range, and deviation from this range may affect their growth rate, feeding enthusiasm and even health. Abnormal fluctuations in water temperature, such as sudden temperature rise or fall, can be discovered in time.

[0041] By using humidity sensors to detect the aquaculture environment at different times and in different areas, we can get the aquaculture humidity environment at each detection time point in each area. Inappropriate air humidity may affect the survival and growth of aquatic products. We can judge the humidity level of the aquaculture environment. Too high or too low humidity may cause some problems. For example, high humidity may cause bacteria to grow, and low humidity may make the surface of aquatic products dry and uncomfortable.

[0042] Through high-definition cameras, the survival status of aquatic products at each stage of production, transportation, storage and processing can be obtained. In the production stage, the growth status, activity status, health status, etc. of aquatic products in the breeding pond can be monitored in real time, abnormalities can be found in time and measures can be taken. At the same time, the breeding environment, such as water quality and water temperature, can be monitored. In the transportation stage, high-definition cameras can record the status of aquatic products during transportation to ensure that the transportation conditions are suitable, such as temperature and humidity, etc., to prevent damage or death during transportation. In the storage stage, the storage environment and aquatic products are continuously monitored to ensure that the storage conditions meet the requirements and avoid deterioration and other problems. In the processing stage, it can supervise whether the processing process is standardized, ensure compliance with hygiene standards and quality requirements, and effectively supervise the workers' operations.

[0043] The data transmission module transmits the collected data to the database accurately and timely. The specific acquisition process is as follows:

[0044] All kinds of aquatic product data collected by sensors and detection equipment are sent to the information management module. During the data transmission process, a series of measures will be taken to ensure the accuracy of the data. The data is checked, and the transmitted data is verified and corrected to ensure that the data is not damaged or tampered with during the transmission process. At the same time, the transmission module will set the appropriate transmission frequency and priority to ensure that key data can be delivered quickly and preferentially. In addition, in order to cope with possible network failures or interruptions, the transmission module will also have a data caching function, and automatically resend the cached data after the network is restored to ensure the integrity of the data. The data transmission module works closely with other modules, so that the entire aquatic product safety monitoring and early warning system can operate efficiently and stably, providing strong protection for aquatic product safety.

[0045] The data analysis module analyzes the data obtained by sensors and equipment to evaluate the safety status and potential risks of aquatic products. The specific acquisition method is as follows:

[0046] By obtaining the water quality parameters at each monitoring time point in each region, the reference water quality parameter interval at each monitoring time point in each region is obtained from the database, marked as the standard water quality parameter interval, and the actual water quality parameters are compared with the standard water quality parameter interval. If the actual water quality parameters are greater than or less than the standard water quality parameters, the actual water quality parameters are judged to be unqualified. If the actual water quality parameters are within the standard water quality interval, they are judged to be qualified. When the actual water quality parameters at each monitoring point in each region exceed the standard water quality interval, the processing and display terminal immediately sends information to the mobile phone terminal of the staff for the area exceeding the standard water quality interval, so that they can know the situation in time to ensure the sustainability of breeding and the quality and safety of aquatic products. Cluster analysis can be used to classify aquatic product data from different regions or batches, and the unqualified water quality parameter areas can be classified into one category for later observation.

[0047] By obtaining the water temperature at each monitoring time point in each area, the water temperature threshold interval at each monitoring time point in each area is obtained from the database, and the actual water temperature is compared with the reference water temperature threshold. If the actual water temperature is greater than or less than the reference water temperature threshold interval, it is judged as unqualified, and if the actual water temperature is within the reference water temperature threshold interval, it is judged as qualified. The water temperature is measured by data to be higher or lower than the corresponding threshold interval. When the sensor receives that the aquaculture water temperature is higher or lower than the threshold interval, the early warning processing module sends a command to the control terminal display to control the chiller to cool the aquaculture area.

[0048] The data analysis module is also used to analyze abnormal fluctuations in aquaculture water temperature. The specific process is: obtain the aquaculture temperature within the preset time range, sort all the aquaculture water temperatures obtained in chronological order, calculate the difference between two adjacent aquaculture temperatures to obtain the adjacent temperature value; if the previous aquaculture temperature is lower than the next aquaculture temperature, mark the adjacent temperature value as the adjacent temperature rise value; if the next aquaculture temperature is higher than the previous aquaculture temperature, mark it as the adjacent temperature drop value; calculate the average temperature value, maximum temperature and minimum temperature of all aquaculture temperatures; substitute their values ​​into the preset formula Output the sudden rise value TB1 or sudden drop value TB2 of the breeding temperature; wherein TSi represents the value of the adjacent temperature rise value, i represents the number of the adjacent temperature rise value, i=1, 2, ..., n1, n1 represents the total number of adjacent temperature rise values; TP represents the value of the average temperature value, Tmax is the value of the maximum temperature, Tmin is the value of the minimum temperature, TJj represents the value of the adjacent temperature drop value, j represents the number of the adjacent temperature drop value, j=1, 2, ..., n2, n2 represents the total number of adjacent temperature drop values;

[0049] η1, η2, η3, η4, η5, η6, η7 are all corresponding preset weight factors, and their sizes are customized by technical personnel in this field according to actual use, such as the values ​​of 0.3, 0.2, 0.25, 0.35, 0.4, 0.2, 0.4 respectively; the abnormal fluctuation threshold 1 and abnormal fluctuation threshold 2 of the water temperature corresponding to the aquatic product are obtained, if the sudden increase value TB1 is greater than the abnormal fluctuation threshold 1, the water temperature is determined to be a sudden increase; if the sudden decrease value TB2 is greater than the abnormal fluctuation threshold 2, the water temperature is determined to be a sudden decrease; the early warning processing module sends the corresponding instructions for sudden temperature increase or sudden temperature decrease to the control terminal for display, and at the same time controls the chiller to cool down or heat up the breeding area, and then performs constant temperature maintenance to make the temperature of the breeding area.

[0050] By obtaining the actual humidity parameters of each area at each monitoring time point, the humidity threshold interval of each area at each monitoring time point is obtained from the database, and the actual humidity parameters are compared with the reference humidity threshold. If the actual humidity parameter is greater than or less than the reference humidity threshold interval, it is judged as unqualified. If the actual humidity is within the reference humidity threshold interval, it is judged as qualified.

[0051] The actual environmental parameters of the breeding area are composed of the water quality parameters at each monitoring point in time in each area, the water temperature parameters at each monitoring point in time in each area, and the humidity parameters at each monitoring point in time in each area.

[0052] By analyzing the aquatic products at each monitoring time point, the survival status of aquatic products at each stage can be obtained. The survival status of aquatic products during production, transportation, storage and processing can be analyzed to obtain the suitable environment for aquatic products and reduce the loss rate at each stage.

[0053] The early warning processing module sends out early warning signals of different levels when the data analysis results show that there are potential safety hazards or exceed the set standards, so that the equipment and relevant personnel can take timely measures. The specific acquisition methods are as follows:

[0054] Through cluster analysis, we obtain the unqualified water quality parameter areas, which are divided into three different stages for processing. The pollution is received by the biosensor in the initial stage, transmitted to the early warning device and then sent to the maintenance personnel's mobile terminal. The maintenance personnel adjust the water exchange device for the water quality pollution area in the initial stage. Since high temperature operation during the day is easy to produce emergency response to aquatic organisms, the water exchange frequency should be updated to once every two days at night, and the water exchange volume should be controlled at 30% of the total water volume. In the development stage, the water exchange frequency should be increased to once a day and the water exchange volume should be controlled at 60% of the total water volume to physically adsorb the pollutants. Severe stage: suspend aquaculture activities to avoid further losses, update the water exchange frequency to twice a day, control the water exchange volume to 100% of the total water volume, comprehensively investigate the pollution source, and properly handle the affected aquatic products, and open up new areas for transfer.

[0055] Depending on the degree of pollution, the amount of feed fed can also be controlled to ensure that the feed and medicine are qualified. The amount of feed can be reduced when the temperature is high or low to prevent the remaining feed from dissolving in the water and further polluting the water quality.

[0056] When the water temperature is too high, an alarm signal is issued through the data analysis module, and the alarm signal is transmitted to the chiller control terminal. The water temperature is cooled by the chiller control terminal to achieve temperature control, and the threshold value of the water temperature is exceeded or lowered for classification. Specifically, the temperature state corresponding to the current monitoring period is normal and marked as a normal temperature interval. Then, an instruction is issued to the chiller to not start. If the aquaculture water temperature is one to five degrees higher than the set standard water temperature interval, it is marked as an abnormal temperature interval, and an instruction is issued to the chiller control terminal to start a chiller device, set the cooling time to ten minutes, and the temperature to twenty degrees. If the equipment temperature is five to ten degrees higher than the set standard equipment temperature interval, it is marked as an abnormal temperature rise interval, and an instruction is issued to the chiller terminal to start two chillers, set the cooling time to twenty minutes, and the temperature to fifteen degrees. If the aquaculture water temperature is ten to fifteen degrees higher than the set standard water temperature interval, it is marked as a high temperature interval, and three chillers are turned on, and the cooling time is set to thirty minutes and the temperature is ten degrees.

[0057] The actual humidity parameters are obtained by analyzing the ambient humidity, and the early warning system then processes the humidity environment of the breeding area at each time and in each area. The early warning system sends a signal to the processing and display terminal, and turns on a ventilation device during the day to enhance air circulation. The device regulates the humidity and discharges the air humidity as quickly as possible. At night, the processing and display terminal turns on two ventilation devices to regulate the humidity of the breeding environment.

[0058] Through the monitoring terminal, we can always pay attention to the production, transportation, storage and processing of aquatic products, and prevent the loss of aquatic products in advance through the early warning system.

[0059] The information management module effectively manages and stores various types of data, facilitating query and traceability, and generates relevant reports to provide a basis for decision-making.

[0060] The information management module will classify and store the water quality parameters, water temperature parameters and humidity parameters in the aquaculture process. Relevant reports are automatically generated according to the templates and rules set in the database. These reports can include aquaculture production reports, water quality monitoring reports, cost-benefit analysis reports, etc. Decision makers can formulate aquaculture strategies, adjust resource allocation, optimize management processes, etc. based on these reports, thereby improving the efficiency and competitiveness of the entire aquaculture business. The data acquisition module and analysis module have data backup and recovery functions to cope with possible data loss risks.

[0062] Real-time collection of relevant data in the production, processing, storage and transportation of aquatic products; including water quality parameters, temperature and humidity to obtain corresponding parameters of the breeding environment;

[0063] By obtaining the water quality parameters at each monitoring time point in each area, the percentage of chemical residues can be obtained from the water quality parameters, and the corresponding reference evaluation value interval of the chemical residue percentage can be obtained from the database. The chemical residue percentage value is compared with the evaluation value interval. If the chemical residue percentage value is not in the evaluation value interval, it is judged as unqualified, otherwise it is judged as qualified. When the actual water quality parameters at each monitoring point in each area at each time exceed the standard water quality interval, the processing display terminal immediately sends information to the staff's mobile phone terminal for the area that exceeds the standard water quality interval. By obtaining the water temperature at each monitoring time point in each area, the water temperature threshold interval at each monitoring time point in each area is obtained from the database, and the actual water temperature is compared with the reference water temperature threshold. If the actual water temperature is greater than or less than the reference water temperature threshold interval, it is judged as unqualified, and if the actual water temperature is within the reference water temperature threshold interval, it is judged as qualified. The water temperature index is measured by data to be higher or lower than the corresponding threshold interval. When the sensor receives that the aquaculture water temperature is higher or lower than the threshold interval, the early warning processing module sends a command to the control terminal display to control the chiller to cool the aquaculture area. By obtaining the actual humidity parameters of each area at each monitoring time point, the humidity threshold interval of each area at each monitoring time point is obtained from the database, and the actual humidity parameters are compared with the reference humidity threshold. If the actual humidity parameter is greater than or less than the reference humidity threshold interval, it is judged as unqualified. If the actual humidity is within the reference humidity threshold interval, it is judged as qualified. The water quality parameters at each monitoring time point in each area, the water temperature parameters at each monitoring time point in each area, and the humidity parameters at each monitoring time point in each area constitute the actual environmental parameters of the aquaculture area. The survival status of aquatic products at each stage is obtained by analyzing the survival status of aquatic products in production, transportation, storage and processing, and the suitable environment of aquatic products can be analyzed to reduce the loss rate at each stage.

[0064] When the data analysis results show that there are safety hazards or exceed the set standards, different levels of early warning signals are issued so that the equipment and relevant personnel can take timely measures. The specific acquisition methods are as follows: the unqualified water quality parameter areas are divided into three different stages for processing. The biosensor receives the pollution in the initial stage, transmits it to the early warning device, and then sends the command information to the maintenance personnel's mobile terminal. The maintenance personnel adjust the water exchange device for the water quality pollution area in the initial stage, and update the water exchange frequency to once every two days, and the water exchange volume is 30% of the total water volume. In the development stage, the water exchange frequency is increased to once a day, and the water exchange volume is controlled at 60% of the total water volume. In the serious stage: update the water exchange frequency to twice a day, control the water exchange volume to 100% of the total water volume, and comprehensively investigate the pollution. Source, and properly handle the affected aquatic products, open up new areas for transfer, and when the water temperature is too high, send an alarm signal to the chiller control terminal, which cools the water temperature. The water temperature above the threshold is graded. Specifically, the temperature state corresponding to the current monitoring period is normal, and a command is issued to the chiller to not start. If the water temperature is within one to five degrees higher than the set water temperature range, it is marked as an abnormal temperature range, and a command is issued to the chiller control terminal to start a chiller device with a set time of ten minutes and a temperature of twenty degrees. If the temperature is within five to ten degrees higher than the set standard equipment temperature range, a command is issued to the chiller terminal to start two chillers with a set time of twenty minutes and a temperature of fifteen degrees.

[0065] For water quality parameters, water temperature parameters and humidity parameters in the aquaculture process, information management will classify and store them, and automatically generate relevant reports based on the templates and rules set in the database. These reports may include aquaculture production reports, water quality monitoring reports, and cost-benefit analysis reports.

Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
