Foodstuff safety multiple item quick detector

Abstract

The invention relates to a multi-project detector for detecting the security of food. The operational power supply separately provides the power to a light path part, a monolithic processor and an auxiliary circuit part. The monolithic processor is separately connected with the light path part, the auxiliary circuit part, an input part and an output part. And the monolithic processor and the auxiliary circuit part are used for calculating and controlling, the input part and the output part are used to input and output the information. The invention can detect the chemical substances which have harm to human body like agricultural chemicals, sulphur dioxide, nitrous acid, rongalite lump, hydrogen peroxide, methyl alcohol, dairy product protein, nitrate and heavy metal, the detecting result is accurate, the detecting speed is quick, the density can be directly showed, the man-machine contact surface is friendly, and the invention has the functions of data storage, inquiry, result printing and GPRS wireless transmission to data server. The invention can be used in real-time, and has the advantages of high detecting efficiency and high automaticity, convenient carrying, practical using, low cost and good effect.

Description

technical field

[0001] The invention relates to a detection instrument, in particular to a food safety rapid detection for rapid detection of multiple detection items such as pesticides, formaldehyde, sulfur dioxide, nitrous acid, diacid, hydrogen peroxide, methanol, dairy protein, nitrate, and heavy metals instrument. Background technique

[0002] At present, the global food safety situation is not optimistic, mainly manifested in the rising food-borne diseases, successive vicious food contamination incidents, new hazards brought by new technologies and techniques of food production / processing, and global food safety and hygiene quality. Caused food trade disputes continue. These issues have become important factors affecting the economic development, international trade and national reputation of various countries. The problem of food pollution due to the abuse of pesticides, food and feed additives, plant and animal growth hormones and environmental pollution is very pr...

Examples

Embodiment Construction

[0017] Below in conjunction with accompanying drawing 1 and accompanying drawing 2 further illustrate how the present invention is realized:

[0018] As shown in Figure 1, a food safety multi-item rapid detector is mainly composed of an optical circuit part 2, a single chip microcomputer 3, an auxiliary circuit part 4, an input and output part, and a working power supply 1, and works through the working power supply 1. The working power supply 1 provides power to the optical path part 2, the single-chip microcomputer 3, and the auxiliary circuit part 4 respectively, and the single-chip microcomputer is respectively connected with the optical path part, the auxiliary circuit part, and the input and output parts. Information input and output.

[0019] The optical path part includes a light source group 6, a colorimetric cell 7, a light source control circuit 8, and an optical signal processing circuit 9, and its components are connected with a single-chip microcomputer.
