System and method for detecting elasticity of livestock and poultry meat as well as fruits and vegetables

Abstract

The invention relates to a system and a method for detecting the elasticity of livestock and poultry meat as well as fruits and vegetables. The system comprises an elasticity detection device, a control box and an upper computer. A control system is arranged in the control box and is used for responding an operating signal transmitted by the upper computer and controlling the rotating speed and the rotating direction of a stepping motor so as to control ascending and descending of a lifting platform; and a pressure signal acquired by a pressure sensor is received and transformed into a digital signal, and the digital signal is transmitted to the upper computer. The upper computer performs data processing on the received digital signal, displays in a curve form and stores detection data in the elasticity detection process. The system adopts integrated modularized design, the control system is separated from a hardware structure, all parts are connected through serial port lines, and the system is easy to carry, install-and-play and low in cost. The pressure sensor is arranged downwards, so the detection precision is improved. The system is simple to operate, the output result is intuitive and easy to understand, and real-time displaying can be realized; meanwhile, the measured detection data can be stored for subsequent data analysis.

Description

Technical field [0001] The invention relates to the technical field of quality and safety detection of livestock and poultry meat, fruits and vegetables, in particular to a system and method for detecting flexibility of livestock and poultry meat, fruits and vegetables. Especially refers to a flexible detection system based on pressure sensor and signal acquisition control system. Background technique [0002] The mechanical properties of food are the main content of the sensory evaluation method. Freshness is one of the important evaluation indexes of livestock and poultry meat, fruits and vegetables. The elasticity of livestock and poultry meat, fruits and vegetables is closely related to the freshness. If the elasticity of livestock and poultry meat, fruits and vegetables can be accurately detected, combined with the relationship between elasticity and quality, the quality of livestock and poultry meat, fruits and vegetables can be accurately predicted.

AI Technical Summary

Problems solved by technology

[0003] In recent years, there have been more instruments that can be used for elastic testing, such as texture analyzers, universal testing machines, etc., but due to the strong professionalism and high prices of texture analyzers and other equipment, the use of these equipment in actual production has been restricted. application
