Method and system for remote online monitoring, sampling and quick inspection of bird flu

Abstract

The invention discloses a remote on-line monitoring, sampling and rapid checking system of poultry influenza epidemic situation, which comprises the following parts: water sample self-collector, test paper box, CCD cam, single-chip set and wireless network transmission, wherein the single-chip set of water sample self-collector drives the test paper box to load the immune colloidal gold test paper automatically; the CCD cam transmits the image of immune colloidal gold test paper and water sample reaction to the monitor center computer through wireless network transmission system to judge the reaction image. The invention can do parting identification of sample directly without differentiating, which provides sthenia criterion for rapid decision of epidemic situation.

Description

technical field [0001] The invention belongs to the field of public health and safety, and relates to the monitoring and prevention of biological viruses. Specifically, it is a method and system suitable for on-site and real-time monitoring of poultry respiratory viruses, especially avian influenza, for remote on-line monitoring of avian influenza virus sampling and rapid screening. . Background technique [0002] Avian influenza is the abbreviation of avian influenza (Avian Influenza, AI), which is an infectious disease syndrome caused by a subtype of influenza A virus. It is called true chicken plague or European chicken plague. Both H and N in the concept of bird flu virus refer to the glycoprotein (protein) of the virus. One glycoprotein is called hemagglutinin (HA), which is like the key of the virus and is used to open the cells of humans or livestock. The other is called Neuraminidase (NA), an enzyme that helps viruses infect other bacteria. ...

AI Technical Summary

Problems solved by technology

[0007] First, the results of artificial fixed-point timing sampling and measurement cannot dynamically reflect the changes in the epidemic situation in the target area, and it is difficult to predict the development of the epidemic situation based on the results;

[0008] 2. The scope of poultry farming is large, the locations are scattered, the quantity is large, and the basic conditions and facilities are not perfect, so the validity of the collected samples cannot be guaranteed;

[0009] 3. It undoubtedly increases the workload of the staff and the chance of being infected;

[0010] 4. There are only a small number of samples infected with avian influenza virus. Such indiscriminate one-by-one typing and identification waste a lot of energy and material resources. Although the chicken embryo virus isolation method is accurate, its shortcomings are also obvious-it takes too long, and it takes too long to extract From the sample to the final result, it takes at least 21 days

[0011] Even the new test standard - fluorescent RT-PCR, still takes four hours. If the number of samples is huge, the time-consuming testing one by one is also huge, which is not conducive to quick decision-making. According to the data search conducted by the applicant, there is no investigation yet. solutions to technical problems in this area
