Description
Technical field
The utility model relates to the correlative technology field of Detecting Pesticide on the food, particularly a kind of instrument for detecting pesticide residue through.
Background technology
Along with growing fast and steadily of China's economy, living standards of the people improve constantly, and are also more and more higher to the requirement of food consumption.Go back to nature, the consumption pollution-free food, the trend and the market that have become new period consumption are moved towards.But environmental pollution has caused very big threat to the hygienic quality of agricultural product, and food poisoning constantly is seen in report, has caused people's extensive concern.
In order to ensure people's edible safety, a lot of wholesale market of agricultural products, the hotel, places such as restaurant are the residues of pesticides situation of applying detection Equipment Inspection agricultural product all, yet, present Detecting Pesticide equipment exists a lot of deficiencies, as the detection method more complicated, way to manage is relatively backward etc., Shanghai Agricultural information firm is in the face of this situation, use modern information technologies, image processing technique and detection technique, researched and developed the residual method for quick of visualization farming, compare with present detection method, this method has all had marked improvement on detection method and way to manage.
The utility model content
The purpose of this utility model is for a kind of instrument for detecting pesticide residue through is provided, and it is existing as problem such as detection method more complicated, way to manage be relatively backward to have solved traditional Detecting Pesticide equipment.
For achieving the above object, the utility model has adopted following technical scheme:
The utility model discloses a kind of instrument for detecting pesticide residue through, it is characterized in that: detector comprise the test paper groove, for test paper provide illumination light source, be heating arrangement, image data acquisition device, data processing equipment and the data output device of test paper heating; The output of image data acquisition device is connected with the signal input part of data processing equipment, and the signal output part of data processing equipment is connected with data output device.
Wherein, described image data acquisition device is a digital camera.Described data processing equipment is single-chip microcomputer or PC.Described data output device is display screen or printer.Described test paper groove is provided with 2-15 test lead.
Its detection may further comprise the steps: will drip the test paper that sample solution is arranged and put into the test paper groove, by heating arrangement test paper is heated, by the pictorial data of the test paper under the image data acquisition device recording light source irradiation and import data processing equipment, data processing equipment is handled the pictorial data of input and is exported result to data output device.Wherein, heating arrangement is heated to 38 degrees centigrade with test paper.
The principles of chemistry: the activity that can suppress acetylcholinesterase in insect nerve center and the peripheral nervous system according to organophosphorus and carbamate chemicals for agriculture, cause the accumulation of nerve conduction medium to influence normal conduction, insect is poisoned to cause death, according to this insect toxicology principle, be used in the detection to residues of pesticides.Low as not containing organophosphorus and carbamate chemicals for agriculture or residual quantity in the extract of fruit vegetable, the activity of enzyme just is not suppressed, and the matrix that adds in the test is just by enzyme hydrolysis or small part hydrolysis, and the drug response on hydrolysate and the test paper produces color; Otherwise, contain a certain amount of organophosphorus and carbamate chemicals for agriculture in the extract as fruit vegetable, the activity of enzyme just is suppressed, the matrix that adds in the test just can not be by enzyme hydrolysis, thereby do not develop the color or change color very little, just can judge the residual condition that contains organophosphorus or carbamate chemicals for agriculture in the vegetables.
Infotech principle: utilize modern information technologies to measure persticide residue.In equipment, test paper groove, camera are installed in the fixed position, the intensity of light source remains unchanged, thereby guarantee the effect of shooting and the degree of accuracy of measurement, camera is taken the colour developing situation of test paper, photographed data is reached data processing centre (DPC), data processing centre (DPC) is a micro-computer processing unit, has advanced computing system, the microcomputer data treating apparatus is taken the colour developing data that obtain according to camera, at first calculate the mean value of color development area color, thereby calculate the content of organophosphorus or carbamate chemicals for agriculture according to color average.Instrument is connected with the residual detection supervisory information system terminal computer of vegetables farming, can realizes uploading automatically of measurement data.Monitoring center system provides the functions such as safe early warning, inquiry, statistics bulletin and online printing to vegetables to the processing of adding up, analyze and tabulate of all kinds of detection data.
Because adopted above scheme, the beneficial effect that the utility model is possessed is: simple to operate, quick, the precision height, cost is low, and the volume of instrument is little, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model instrument for detecting pesticide residue through.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of instrument for detecting pesticide residue through, as shown in Figure 1, comprise test paper groove 1, for test paper provide illumination light source 2, be heating arrangement 3, digital camera 4 (image data acquisition device), single-chip microcomputer 5 (data processing equipment) and the LCDs 6 (data output device) of test paper heating; The output of digital camera is connected with the signal input part of single-chip microcomputer, and the signal output of single-chip microcomputer is connected with LCDs.Described test paper groove is provided with 8 test leads.
The method of Detecting Pesticide is chosen representational vegetable sample, rinses out surperficial earth, is cut into the square fragment in the 1cm left and right sides, sample thief 1g puts into beaker or extraction flask, adds 5mL and extracts solution, vibration 1min-2min, pour out extract, leave standstill 3min-5min, stand-by.Pipette an amount of sample solution with transfer pipet and drip to test paper, have the test paper of sample solution to put into the test paper groove, test paper is heated, generally heated 2-3 minute by heating arrangement with dripping.When treating that temperature reaches 38 degrees centigrade, start and measure button, by the pictorial data of the test paper under the digital camera recording light source irradiation and import single-chip microcomputer, single-chip microcomputer is handled and result is uploaded to central database automatically and exports LCDs simultaneously to, reading displayed information the pictorial data of input.That display message comprises is qualified, exceed standard and severe overweight.If equipment links to each other with computer, can realize the measurement of computer commander equipment, realize uploading and monitoring management of data simultaneously.
