In agricultural chemicals it is a large amount of using and it is unreasonable the use of caused pollution by pesticides and residue problem and its hazard analysis and HACCP of generation is tight
Weight, cause national governments and the extensive concern of the public.Agricultural production for the scattered production of small-scale peasant household of China shows
Shape, will control residues of pesticides, and must just develop can carry out the quick means for realizing detection to the residues of pesticides of fruit and vegetable surfaces.
Traditional detection gimmick mainly uses gas chromatograph, liquid chromatograph, gas chromatograph-mass spectrometer, LC-MS instrument, hair
Cons electrophoresis method, thin-layered chromatography, Spectrographic method etc., it is quantitative accurate although these method analysis precisions are high, its sample
Complex pretreatment, the detection operating personnel that time-consuming, high cost, needs are skilled in technique, it is impossible to the need for realizing quick detection.Food
Residues of pesticides in product have a strong impact on the healthy of consumer, it is therefore desirable to a kind of fruits and vegetables Pesticide Residues quick detection it is micro-
Type, portability, detecting instrument simple to operate so that whether ordinary people has agricultural chemicals exceeded edible water fruits and vegetables, energy
It is enough quickly to detect.
The content of the invention
Whether there is agriculture it is an object of the invention to provide the detection water fruits and vegetables that a kind of ordinary people can be used in family
The intelligent chopsticks of medicine residual.
The present invention provides a kind of intelligent chopsticks of quick detection fruits and vegetables Pesticide Residues, utilizes acetylcholine ester enzyme sensor
Fast detecting pesticide residue, it is easy to carry, it is simple to operate.
To achieve the above object, of the invention quick detection fruits and vegetables Pesticide Residues based on acetylcholine ester enzyme sensor
Intelligent chopsticks.The intelligent chopsticks include two, wherein detection circuit is provided with one, it is acetylcholine ester enzyme sensor, micro-
Processor, the first wireless transport module, the first power module；Another of the intelligent chopsticks includes memory module, second
Wireless transport module, display screen, second source module.
The detection circuit is followed in series to form by power supply circuit, constant voltage circuit, acetylcholinesterase detection circuit；It is described
Power supply circuit is connected in parallel that there is provided+5V and -5V dual power supplies using photovoltaic conversion chip；The constant voltage circuit is the second
Acetylcholinesterase detects the operating voltage of circuit with stable；The acetylcholinesterase detection circuit and the acetylcholine ester
Enzyme sensor is connected, and the nA level Current amplifiers that the acetylcholine ester enzyme sensor is exported simultaneously transform into voltage detecting letter
Number, it is output to microprocessor.
Detection program is run on the microprocessor, the voltage detection signal received is carried out after digital filtering, is utilized
The current value that relative standard deviation (RSD) check addition is stablized, is compared with current value before the suppression of setting, show that enzyme presses down
Rate processed and qualitative conclusions；Fruits and vegetables pesticide variety and national Pesticide Residue database are implanted on the microprocessor, will be detected
Data carry out quantitative analysis, the concentration of quantitative exceeded agricultural chemicals.
The above-mentioned conclusion drawn is passed to second wireless transport module, described by first wireless transport module
Two wireless transport modules are included it on the display screen, and store into the memory module.
Further, the testing result is delivered to intelligent terminal by second wireless transport module, and the intelligence is eventually
Display data, figure are held, all testing results are collected and analyzed.
First power module and second source module provide required electric energy to the intelligent chopsticks.
The beneficial effects of the present invention are：The present invention provides a kind of intelligent chopsticks of quick detection fruits and vegetables Pesticide Residues,
Facilitate family to use, be detection band to greatly facilitate, relative to the knowledge and equipment that passing detection must possess specialty, limitation
Use scope；Acetylcholine ester enzyme sensor is arranged in chopsticks by the present invention, and compact conformation, easy to carry, detection are quick accurate
Really, it is simple to operate, practical.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the principle schematic of present invention detection residues of pesticides.
Embodiment
In order that the purpose of the present invention, technical scheme are clearer, below in conjunction with the accompanying drawings and embodiment, to present invention progress
Detailed description.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this hair
It is bright.
The present invention provides a kind of intelligent chopsticks of the quick detection fruits and vegetables Pesticide Residues based on acetylcholine ester enzyme sensor
Son, as shown in figure 1, the intelligent chopsticks include two, wherein being provided with detection circuit, acetylcholinesterase sensing in one
Device, microprocessor, the first wireless transport module, the first power module；Another of the intelligent chopsticks includes memory module,
Second wireless transport module, display screen, second source module.
The detection circuit is followed in series to form by power supply circuit, constant voltage circuit, acetylcholinesterase detection circuit, described
Acetylcholine ester enzyme sensor is three-electrode system, and working electrode, reference electrode and auxiliary electrode are fixed on the working electrode
There is acetylcholinesterase.
Just specific description is done in the implementation of the intelligent chopsticks below：
The chopsticks for including acetylcholine ester enzyme sensor are put into immersion 10 minutes in surveyed solution first, then,
Working power is opened, the intelligent chopsticks are tested the solution, the acetylcholine ester enzyme sensor detection is described molten
