Description
Technical field
The present invention relates to a kind of monitoring system of internet of things and application of Practice for Pesticide Residue in Agricultural Products, belong to Practice for Pesticide Residue in Agricultural Products detection technique field.
Background technology
Vegetables and fruit are one of most important ingredients in people's diet.As everyone knows, the population of 30 percent has nearly been supported in the soil that China make use of less than the earth 10, and agricultural chemicals then becomes prevention and elimination of disease and pests, ensures the important weapon that increasing crop yield increases income.Agricultural chemicals plays the preventive and therapeutic effect of disease pest and weed in the planting process of fruits and vegetables, but agricultural chemicals can not all be absorbed by plants, and major part still remains in fruit surface.In promotion modern agricultural production develops rapidly, the human society that appears as of agricultural chemicals brings huge economic interests.But the origin of chemistry of pesticide material adds and the use that people's large area is not scientific and reasonable manages inadequate specification in addition, the balance causing the ecosystem is destroyed, and Pesticide Residue displays thereupon.
Bread is the staff of life, and along with the raising of people's living standard, people more and more pay close attention to the healthy diet in daily life.Strengthen foods supervision, pay close attention to the well-being of the people, allowing the common people be able to eat " safety fruits and vegetables " is the basic premise ensureing the people's livelihood, but annual because ediblely cause poisoning event containing residues of pesticides food and occur repeatedly.The edible food containing residues of pesticides can cause people's acute poisoning.The agricultural byproducts that long-term edible residues of pesticides exceed standard, can cause the generation of various diseases, the serious follow-on health of even impact.
From the 1950's, China starts the research of Analytical Techniques of Pesticide Residues.Between the present situation that science and technology at that time falls behind, Analytical Techniques of Pesticide Residues method is also limitation very, analytical approach its be only limitted to chemical method, colourimetry and bioassay method, and detection method is single, has detected in time, and its sensitivity is not high yet.
Along with the iterative method of Urbanization Construction, people are mainly market and supermarket for the main procurement method of fruits and vegetables.But on the one hand because checkout equipment high cost is equipped with except detecting instrument except relevant governmental detects department, these fruits and vegetables selling posts are but seldom equipped with the relevant device of the residual detection of agriculture and Detection Information cannot openly to fruits and vegetables buyer; On the other hand, detecting the existing checkout equipment of website is that detection efficiency is low, and testing process is complicated based on large-scale checkout equipment that is meteorological, liquid phase, cannot realize hyperchannel and detect fast and the not easily universal and popularization of checkout equipment cost height.
