Food texture detection system based on virtual instrument technology

A food texture automatic measurement and analysis system was developed. This system adopts the advanced virtual instrument technology combined with the single-chip technique, integration of mechanics and the sensor technique. The module circuits were designed in the hardware system, including force sensors, displacement and deformation sensors, timer, signal conditioner, the data acquisition, the serial-port communication and the expanded LCD. Based on the virtual instrument developing platform of LabWindows/CVI, the data acquisition, the interface demonstration and the real-time of data processing were realized by means of multi-thread technique. The experimental results indicate that this system cannot only increase the measurement accuracy and anti-interference capabilities, but also perfect the measurement performance. The study has great significance in both theory and practice.
