The utility model comprises an optical signal generation device, an electro optical signal interpreter installation, a signal amplification circuit, and measuring and output device. The signal generated by the optical signal generation device shall be converted into the electronic signal through the electro optical signal interpreter installation. After having had its circuit amplified, the electronic signal shall be inputted to the measuring device for detection, and the detection results shall then be outputted by the measuring device through the output device. Wherein, the optical signal generation device comprises a optical source, a filter, a lens and a colorimetric cell. The light of the optical source, after successively passing through the filter, lens and colorimetric cell, shall finally shine out onto the said electro optical signal interpreter installation which is of photoelectric cell. The measuring detection device adopts the CPU and A/D switching circuit.
Description
Technical field
The utility model belongs to food residual toxicity pick-up unit field, especially a kind of residual toxicity device for fast detecting.
Background technology
Agricultural product are carried out residual toxicity to be detected and to be one and to have very important thing.On the one hand, because the fruits and vegetables pollution problem becomes increasingly conspicuous, it is healthy to have a strong impact on people.Since the nineties in 20th century, China vegetables and fruit residues of pesticides cause that people and animals' death incident frequently takes place.Pesticide poisoning incident 247349 examples take place in 26 provinces and cities in 1992 to 1996 whole nations, dead 24612 people, and China every year, the number because of pesticide poisoning accounted for 50% of the similar accident number in the world.Along with the raising day by day of people's living standard, require agricultural product not only quality to get well, and want health pollution-free, in the international market, strict restriction is made to the persticide residue of farm imports in many developed countries and area.Because the many agricultural product of China exist residues of pesticides to a certain extent, developed country's " green barrier " is also more and more higher, causes the foreign exchange earning of agricultural product to be a greater impact.
Because China is the laws and regulations imperfection aspect residues of pesticides for a long time, some peasant's legal consciousness faint, the high malicious remains of pesticide prevention and elimination of disease and pests of using forbidding in a large number, limiting the use of for the figure immediate interest, arbitrarily increase the using dosage and the access times of agricultural chemicals, even violation safety interval of pesticide pollution, this has not only jeopardized the healthy of people, has brought many negative effects for the vegetables production and selling, and has seriously hindered the sustainable development of agricultural production.How performing the production and the detection of non-polluted farm product, is a baptism to this large agricultural country of China.
The testing of residual toxicity on the fruits and vegetables, in the institutionalization already of many developed countries, the method of inspection of residual toxicity is used the residues of pesticides in the technology for detection fruits and vegetables such as immunoassay, supercritical fluid extraction and supercritical fluid chromatography, capillary zone electrophoresis more in these countries, these all are good discrete testing technology, and accuracy and precision are all very high.
But the detection method of developed country also is not suitable for All Countries, be because the detection method of developed country needs expensive equipment on the one hand, and the testing staff need have higher technical merit, the testing expense costliness, length expends time in, be in developed country on the other hand, the concentration of production of commodity vegetables, after the wholesale dealer is transported to the market with the vegetables of gathering by the place of production, promptly be stored in the warehouse, request checking is declared by the residual toxicity check unit under local government, in case defective, destroy immediately.And other countries China for example, fruits and vegetables production disperses relatively, promptly adopts promptly and sells, and can not analyze big two samples of being inspected by random samples from the market with large-sized analytic instruments such as gas chromatographies, therefore must adopt the checkout equipment that meets China's fruits and vegetables production and marketing characteristics, carry out the detection of quickly, efficiently and accurately.
The utility model content
The purpose of this utility model provides a kind of residual toxicity pick-up unit of a kind of detection sensitivity height, detection speed is fast, selectivity is high suitable China's national situation.
The technical solution of the utility model is: the residual toxicity device for fast detecting, it is characterized in that comprising optical signal generation apparatus, the photosignal conversion equipment, signal amplification circuit, measurement mechanism and output unit, the light signal that optical signal generation apparatus produces converts electric signal to by the photosignal conversion equipment, electric signal is through behind the amplifying circuit, being input to measurement mechanism detects, measurement mechanism is exported testing result by output unit, wherein optical signal generation apparatus comprises light source, optical filter, lens and cuvette are formed, the light that light source sends passes through optical filter successively, behind lens and the cuvette, shine on the photosignal conversion equipment, described photosignal conversion equipment is a photoelectric cell, and measuring pick-up unit is CPU and A/D change-over circuit.
Described output unit comprises display, printer and/or network connection device.
Effect of the present utility model is: the residual toxicity device for fast detecting, it is characterized in that comprising optical signal generation apparatus, photosignal conversion equipment, signal amplification circuit, measurement mechanism and output unit, the light signal that optical signal generation apparatus produces converts electric signal to by the photosignal conversion equipment, electric signal is input to measurement mechanism and detects through behind the amplifying circuit.Therefore can reduce the volume of equipment, in light weight, be easy to carry.Have characteristics highly sensitive, that detection speed is printed testing result soon, automatically simultaneously, owing to be connected with the database of accepting testing result, can be in transmission over networks.
Residual toxicity device for fast detecting of the present utility model not only is useful in big wholesale vegetable market, the fast detecting station is set up in important vegetables producing region, also be applicable to village, villages (towns), large-scale canteen, even can set up mobile detection station at the sub-transaction of greengrocer scene.Can really be implemented to field speed and survey, can prevent people and animals to eat by mistake to contain the vegetable and fruit of high poison, persistent pesticide, guarantee people's safe diet that secures good health.
Below in conjunction with drawings and Examples the utility model is described further.
