Pesticide residue detector

Abstract

The invention discloses a pesticide residue detector which relates to the field of detection of agricultural products, and solves the problems in the prior art. The detector comprises a master controller, an LED light source group, a micro printer, a liquid crystal touch display screen, a storage battery, a USB interface, a photoelectric sensor, a power interface and a detection device, wherein the master controller consists of a single chip microcomputer, and a storage device, an analog / digital (A / D) converter and a time controller which are electrically connected with the single chip microcomputer; the LED light source group, the micro printer, the liquid crystal touch display screen and the storage battery are respectively and electrically connected with the single chip microcomputer; the USB interface is electrically connected with the storage device; the photoelectric sensor is electrically connected with the A / D converter; the power interface is electrically connected with the storage battery; the detection device, the LED light source group and the photoelectric sensor are positioned on the same horizontal line; the LED light source group consists of multiple LED light sources and has the central wavelength of 412nm; the detection device consists of multiple detection channels; and the LED light sources correspond to the detection channels one by one. According to the pesticide residue detector disclosed by the invention, a keyboard and a display are fused into a whole by using the liquid crystal touch display screen, the deadweight of the detector is lightened, and the detector has the advantages of being convenient to carry, simple to operate, large in viewing angle, high in transmissivity and low in energy consumption, being used by non-professionals and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural product detection, in particular to a pesticide residue detector capable of measuring the content of organic phosphorus and carbamate pesticides in agricultural products. Background technique [0002] my country is a large agricultural country, and the treatment of crop diseases and insect pests mainly depends on pesticide spraying, which makes the use of pesticides in our country much higher than other countries. After spraying on crops, most of the pesticides will be transformed and dispersed in the In nature, there are still a small amount of pesticide residues on crops. Long-term consumption of agricultural products with pesticide residues will greatly endanger people's physical and mental health. However, the use of pesticides in my country is mostly organophosphorus and carbamate pesticides. It is particularly important to detect the amount of pesticide residues. [0003] At present, the...

Problems solved by technology

This method is qualitatively rough, has low accuracy, and has a narrow scope of application for pesticides.

[0004] Pesticide residue detection instruments currently on the market have defects such as complex operation, large volume, high price, small number of detections, and long detection cycle, and can only be used at places with power sources, and require professionals to operate them, which cannot satisfy the market public Therefore, it is necessary to invent a pesticide residue detection equipment that is low in cost, simple in operation, fast in detection speed and able to meet market demand.
