Description
技术领域Technical Field

背景技术Background Art
随着水产养殖业的快速发展，水产品安全问题日益受到关注，水产品中的污染物，如重金属，对消费者健康构成潜在威胁，传统的水产品污染物检测方法通常需要破坏水产品样本，不仅导致样本无法再次使用，还可能影响检测结果的准确性，因为破坏过程可能改变污染物的状态或浓度，且还需要专业人员来操作和维护专业的设备，增加了人力成本和技术门槛；因此需要一种简单快速的非破坏性的水产品检测方法。With the rapid development of aquaculture, the safety of aquatic products has received increasing attention. Pollutants in aquatic products, such as heavy metals, pose a potential threat to consumer health. Traditional methods for detecting pollutants in aquatic products usually require the destruction of aquatic product samples, which not only makes the samples unusable, but may also affect the accuracy of the test results because the destruction process may change the state or concentration of the pollutants. Professionals are also required to operate and maintain professional equipment, which increases labor costs and technical barriers. Therefore, a simple, fast, non-destructive method for detecting aquatic products is needed.
但是，传统的水产品污染物检测方法，并不能在检测污染物含量的同时了解饲料投喂对水产品污染物含量的影响，从而帮助养殖者可以根据实际情况调整饲料配方和投喂策略，选择更加环保、安全的饲料，或者改变投喂时间和频率等，以达到降低水产品污染物含量的目的。However, traditional methods for detecting pollutants in aquatic products cannot simultaneously detect the pollutant content and understand the impact of feed feeding on the pollutant content in aquatic products, thereby helping farmers to adjust feed formulas and feeding strategies according to actual conditions, choose more environmentally friendly and safe feeds, or change feeding time and frequency, etc., in order to achieve the goal of reducing the pollutant content in aquatic products.

对水产品的分泌物进行分析，输出污染物含量表征值；将污染物含量表征值WH与污染物含量表征值阈值WHY进行对比分析；Analyze the secretions of aquatic products and output the pollutant content characterization value; compare and analyze the pollutant content characterization value WH with the pollutant content characterization value threshold WHY;
若污染物含量表征值WH≤污染物含量表征值阈值WHY，则判定水产品污染物含量低，生成污染物含量正常信号；If the pollutant content characterization value WH ≤ the pollutant content characterization value threshold WHY, it is determined that the pollutant content of the aquatic product is low, and a pollutant content normal signal is generated;
若污染物含量表征值WH＞污染物含量表征值阈值WHY，则判定水产品污染物含量高，生成污染物含量异常信号；If the pollutant content characterization value WH>the pollutant content characterization value threshold WHY, it is determined that the pollutant content of the aquatic product is high, and a pollutant content abnormality signal is generated;
示例性的，污染物含量表征值的获取过程为：Exemplarily, the process of obtaining the pollutant content characterization value is as follows:
将分泌物进行区域性划分，获取分泌物子区域；Divide the secretion into regions to obtain secretion sub-regions;
其中，区域划分的方法为：将分泌物从中心到外表面划分为若干个区域，且每个区域的体积一致；The method of area division is: the secretion is divided into several areas from the center to the outer surface, and the volume of each area is consistent;
利用光谱测试法，分别对每个子区域的分泌物进行分析，检测其中污染物的种类和含量，并将不同种类的污染物含量进行加权求和，输出各子区域分泌物的污染物含量总和，将污染物含量总和与污染物含量总和阈值进行比值计算，输出污染物含量参数；Using the spectral testing method, the secretions of each sub-area are analyzed respectively to detect the types and contents of pollutants therein, and the contents of different types of pollutants are weighted and summed to output the total pollutant content of the secretions of each sub-area, and the total pollutant content is calculated by ratio with the total pollutant content threshold to output the pollutant content parameter;
其中，包括光谱测试法：荧光光谱法；Among them, the spectral test methods include: fluorescence spectroscopy;
需要说明的是：加权求和是为了综合考虑不同污染物对整体污染水平的影响，因为不同的污染物会具有不同的毒性和环境风险；加权的依据包括：污染物的毒性：不同污染物对人体健康或环境的潜在危害程度不同，毒性更高的污染物在加权时则赋予更大的权重；污染物的生物累积性：一些污染物容易在生物体内累积，并通过食物链放大，对人类和生态系统造成更大影响，所以污染物在加权时还需考虑其生物累积性；It should be noted that the weighted summation is to comprehensively consider the impact of different pollutants on the overall pollution level, because different pollutants have different toxicity and environmental risks; the basis for weighting includes: Toxicity of pollutants: Different pollutants have different potential harm to human health or the environment, and pollutants with higher toxicity are given greater weights when weighting; Bioaccumulation of pollutants: Some pollutants tend to accumulate in organisms and amplify through the food chain, causing greater impact on humans and ecosystems, so the bioaccumulation of pollutants must also be considered when weighting;
将各子区域分泌物的污染物含量参数进行差值计算，输出污染物含量参数偏差值；Perform difference calculation on the pollutant content parameters of the secretions in each sub-area and output the deviation value of the pollutant content parameters;
基于污染物含量参数偏差值，分析分泌物是否受到水质影响，并生成分泌物影响信号；Based on the deviation value of the pollutant content parameter, analyze whether the secretion is affected by the water quality and generate a secretion impact signal;
其中，分泌物影响信号包括：分泌物受到影响信号和分泌物未受影响信号；The secretion-affected signal includes: a secretion-affected signal and a secretion-unaffected signal;
预设污染物含量参数偏差值阈值，将污染物含量参数偏差值与污染物含量参数偏差值阈值进行对比分析；Preset a pollutant content parameter deviation value threshold, and compare and analyze the pollutant content parameter deviation value with the pollutant content parameter deviation value threshold;
若污染物含量参数偏差值≤污染物含量参数偏差值阈值，则说明分泌物未受到水质的影响，生成分泌物未受影响信号；If the pollutant content parameter deviation value is less than or equal to the pollutant content parameter deviation value threshold, it means that the secretion is not affected by the water quality, and a secretion unaffected signal is generated;
若污染物含量参数偏差值＞污染物含量参数偏差值阈值，则说明分泌物未受到水质的影响，生成分泌物受到影响信号；If the pollutant content parameter deviation value is greater than the pollutant content parameter deviation value threshold, it means that the secretion is not affected by the water quality, and a signal that the secretion is affected is generated;
需要说明的是：当水产品处于受污染的水质环境中时，水产品会通过皮肤、鳃或其他途径吸收或吸附水中的污染物，污染物可能会附着在分泌物的表面，也可能水质稀释分泌物表面的污染物含量，导致在检测时分泌物表面污染物的含量与分泌物内部的污染物含量不同；It should be noted that when aquatic products are in a polluted water environment, they will absorb or adsorb pollutants in the water through their skin, gills or other pathways. The pollutants may adhere to the surface of the secretions, or the water may dilute the pollutant content on the surface of the secretions, resulting in the content of pollutants on the surface of the secretions being different from that inside the secretions during testing.
基于分泌物未受影响信号，将分泌物所有子区域的污染物含量参数进行均值计算，输出污染物含量参数均值；Based on the unaffected signal of the secretion, the pollutant content parameters of all sub-areas of the secretion are averaged and the pollutant content parameter average is output;
基于所有未受到水质影响的分泌物，将所有分泌物的污染物含量参数均值进行求均值计算，输出污染物含量表征值，并将污染物含量表征值标记为WH；Based on all secretions that are not affected by water quality, the mean values of the pollutant content parameters of all secretions are calculated, and the pollutant content representation value is output, and the pollutant content representation value is marked as WH;
本发明实施例的构思为：随着水产养殖业的快速发展，水产品安全问题日益受到关注，水产品中的污染物，如重金属，对消费者健康构成潜在威胁，传统的水产品污染物检测方法通常需要破坏水产品样本，不仅导致样本无法再次使用，还可能影响检测结果的准确性，因为破坏过程可能改变污染物的状态或浓度，且还需要专业人员来操作和维护专业的设备，增加了人力成本和技术门槛；因此需要一种简单快速的非破坏性的水产品检测方法，通过定期对水产品分泌物进行检测，分析分泌物中污染物的含量，输出污染物含量表征值，再基于污染物含量表征值，水产品污染物含量进行评估，生成污染物含量评估信号，从而可以在水产品养殖过程中，在不破坏水产品的前提下，对水产品污染物进行检测，生成污染物含量评估信号，通过收集水产品的分泌物进行分析，无需破坏水产品样本，保证了水产品的完整性和安全性，同时便于养殖人员了解水产品的污染情况，为制定针对性的处理措施提供科学依据。The concept of the embodiment of the present invention is as follows: With the rapid development of aquaculture, the safety of aquatic products has received increasing attention. Pollutants in aquatic products, such as heavy metals, pose a potential threat to consumer health. Traditional aquatic product pollutant detection methods usually require the destruction of aquatic product samples, which not only makes the samples unusable, but also may affect the accuracy of the detection results, because the destruction process may change the state or concentration of the pollutants, and also requires professionals to operate and maintain professional equipment, which increases labor costs and technical barriers; therefore, a simple and fast non-destructive aquatic product detection method is needed, by regularly detecting aquatic product secretions, analyzing the content of pollutants in the secretions, outputting a pollutant content characterization value, and then based on the pollutant content characterization value, the pollutant content of the aquatic product is evaluated to generate a pollutant content evaluation signal, so that during the aquatic product breeding process, without destroying the aquatic product, the aquatic product pollutants can be detected and the pollutant content evaluation signal can be generated. By collecting the secretions of aquatic products for analysis, there is no need to destroy the aquatic product samples, which ensures the integrity and safety of the aquatic products, and at the same time facilitates the breeding personnel to understand the pollution of the aquatic products, providing a scientific basis for formulating targeted treatment measures.

其中，投喂量参数WL为：目标饲料投喂的投喂量与投喂量阈值之比；Among them, the feeding amount parameter WL is: the ratio of the feeding amount of the target feed to the feeding amount threshold;
投喂间隔参数WJ为：目标饲料该次投喂时间与目标饲料上一次投喂时间之间的时间间隔，将时间间隔与时间间隔阈值进行比值计算，即为投喂间隔参数；The feeding interval parameter WJ is: the time interval between the current feeding time of the target feed and the last feeding time of the target feed. The time interval is calculated by the ratio of the time interval threshold to obtain the feeding interval parameter.
通过公式：，计算获得影响时间∆T，其中，∆t为预设时间间隔，a1、a2为预设比例因子，且均大于0；By formula: , calculate and obtain the impact time ∆T, where ∆t is the preset time interval, a 1 and a 2 are preset proportional factors, and both are greater than 0;
需要解释说明的是：每一次目标饲料投喂后的影响时间均要根据对应次数目标饲料投喂进行计算；It should be explained that the impact time after each target feed is calculated based on the corresponding number of target feeds.
示例性的，分析影响时间内污染物含量波动曲线的趋势，并生成曲线趋势信号的过程为：对影响时间内污染物含量波动曲线的趋势进行分析；Exemplarily, the process of analyzing the trend of the pollutant content fluctuation curve within the impact time and generating the curve trend signal is: analyzing the trend of the pollutant content fluctuation curve within the impact time;

The larger the value of the influence coefficient, the more times the pollutant content characterization value shows an upward trend.
