Abstract:

The material level measurement technology in the fermentation process of big pot rice wine was studied, using radio frequency admittance technology to achieve the measurement of material level, and the hanging problem was analyzed and improved to ensure the accuracy of fermentation process and to improve the quality of rice wine. The design of the material level measurement system, the accurate clock setting system scheme, and the sampling integral circuit and measurement circuit were performed to further improve the accuracy of level measurement technology. This technology fills the gap in measurement of the level measurement technology of rice wine fermentation. For level measurement technology to design a set of material level control system, the hardware part of the material level measuring system power circuit was designed by the microcontroller PWM output clock and sampling integral circuit two options, to further improve the accuracy of material level measuring technology. The mathematical model of fermentative admittance before and after the fermentation was proposed, and the monitoring system of upper computer was designed using visual studio 2015, so that the content in fermentation tank could be viewed online in real time. The linkage between fermentation tank was realized by using RFID technology and wireless communication between the monitoring system, not only improved the reliability of data transmission, also to filled the domestic blank in yellow wine yeast a measurement technology.
