Flue-cured tobacco multi-parameter real-time monitor

Abstract

The invention discloses a multi-parameter real-time monitor for tobacco curing. An existing monitor for the tobacco curing is relatively single in function and insufficient in measured parameter. According to the multi-parameter real-time monitor for the tobacco curing, the functions of measuring leaf gap wind speed and leaf gap wind pressure are added on the basis that the environment temperature of a curing barn and the surface temperature of tobacco leaves are measured. According to the multi-parameter real-time monitor for the tobacco curing, the output end of a leaf surface temperature sensor, the output end of a leaf gap wind speed sensor and the output end of a leaf gap wind pressure sensor are connected with the input end of a signal conditioning module, the output end of the signal conditioning module is connected with the input end of an A / D conversion module, and signals are processed and then transmitted to a single chip microcomputer; output signals of an environment humidity sensor are directly connected to a single chip microcomputer processing module; a liquid crystal display module, a button module, a communication module, a clock module and a storage module are all directly connected with the single chip microcomputer processing module; a power module supplies power for a host machine part. The multi-parameter real-time monitor for the tobacco curing achieves the real-time monitoring of multiple parameters of the environment temperature, the leaf surface temperature, the leaf gap wind speed and the leaf gap wind pressure of the curing barn, and has the advantages of being high in precision, convenient to carry and the like.

Description

technical field [0001] The invention relates to the field of tobacco leaf curing and the field of sensor measurement and control, in particular to a multi-parameter real-time monitor for flue-cured tobacco. Background technique [0002] For a long time, the quality of tobacco leaf curing has always been the most critical and direct factor affecting the income of tobacco farmers. Before the rise of sensor measurement and control technology, the grasp of the tobacco leaf curing process was entirely based on the personal experience of the tobacco curing personnel. Along with the development of tobacco science and technology, scholars engaged in tobacco research in my country have also continuously absorbed and introduced foreign excellent tobacco leaf curing technology and experience, and put forward the theory of "three-stage" flue-cured tobacco and intensive flue-cured tobacco in China, and dry and wet The method of monitoring the ambient temperature and humidity in the flue-...
