ATP fluorescent food detector

Abstract

The invention discloses an ATP fluorescent food detector, comprising a hardware part and a software part, wherein the hardware part comprises a central control module, a power module, a fluorescent detection module, a communication module, an input module, a display module, a data memory module, a man-machine dialogue module, a signal acquisition and amplification module, an A / D conversion module, an auxiliary circuit module and a sampling test module; the software part adopts a three-layer structure comprising an operating system layer, an application layer and a hardware layer from inside to outside; the operating system layer is connected with the hardware layer by the application layer; the operating system layer adopts a mu C / OS-II embedded operating system. The fluorescent food detector adopts a method of combining an ATP bio-chemiluminescence method and the embedded system, so that the time for detecting the content of microorganisms is greatly shortened; the detector is small in size, convenient to carry, low in power consumption, long in stand-by time and high in detection precision, and is capable of conveniently detecting a sample in real time, thus having good application prospect in the field of food production hygiene inspection.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an ATP fluorescent food detector. Background technique [0002] Desktop ATP fluorescence method microbial detector [0003] (1) Long time: Compared with conventional bacterial plate counting, the main characteristics of the detection system are long cycle and poor accuracy of results. The plate count method takes two days to get the detection data. Therefore, the adoption of the R&D quick inspection system is a necessary condition for implementing the HACCP certification system, establishing a food safety early warning and traceability system, and improving work efficiency and management standardization. [0004] (2) Inconvenient to carry: The traditional ATP fluorescence detection instrument components need to be placed in a small portable tool box, with a total weight of no more than 2.0 kg, which is inconvenient to carry. [0005] (3) Complicated operation: It is necessar...
