Problems solved by technology

It can be seen from this that it is very necessary to distinguish between chilled and thawed fish in daily life, but it is difficult to manually identify these two kinds of fish, and there is currently no device that can distinguish between chilled and thawed fish

Embodiment Construction

[0036] In order to further illustrate the technical content of the present invention, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, the internal circuit of the instrument (that is, the automatic detector) connects the fixed value resistor (4), the metal probe (8), and the Arduino Uno development board (3) in series. Among them, the Arduino Uno development board (3) has programmed the signal generation program in advance, one end is connected to the digital interface, the other end is grounded, and it is powered by a 5V DC power supply (7). This constitutes a measurement circuit.

[0038] Connect the high-frequency AC voltage sensor (5) in parallel to both ends of the fixed value resistor (4) and the metal probe (8), and connect the output terminals to the analog ports of the Arduino Mega 2560 development board (2). Among them, the Arduino Mega 2...

Abstract

The invention provides an automatic detector and a detection method for rapidly detecting a fish body storage mode without damage. According to the automatic detector, an Arduino Uno development boardis used as a signal generator to generate alternating current signals with different frequencies; an Arduino Mega 2560 development board is used as a central processing unit, voltage information of corresponding elements is received, calculation and analysis are carried out according to a program burnt in advance, a result is displayed on an LCD display screen, and intelligent detection is achieved. Instruments are used for replacing manual work to achieve detection of the fish body storage mode, and the automatic detector is convenient, rapid, simple and practical.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and in particular relates to a novel instrument for detecting the storage mode of fish bodies. Background technique [0002] There are two types of refrigerated fish currently on the market: chilled and frozen. Iced fresh fish refers to the fish that has been kept below 4°C after being caught, and the fish that has not been frozen is usually stored for less than 10 days; thawed fish refers to the fish that has been frozen and stored (below -20°C) after being caught, and then re-frozen. Thawed fish can be stored for 6 to 12 months in frozen storage, which has a long storage period. Iced fresh fish has better meat flavor and taste, and is more nutritious and priced than thawed fish. In order to pursue profits, some enterprises sell thawed fish as iced fresh fish, which seriously damages the interests of consumers. It can be seen from this that it is very necessary to distinguish c...
