Abstract

The invention relates to a flue-curing barn humidity monitoring device, which comprises probe circuits, a probe selection circuit, a humidity acquisition circuit, a control circuit, a power supply, a power supply circuit, a display module and a communication module. Specifically, the output ends of the probe circuits are connected to the input end of the probe selection circuit, the output end of the probe selection circuit is connected to the input end of the humidity acquisition circuit, the output end of the humidity acquisition circuit is connected to the control circuit, and the output end of the control circuit is connected to the input end of the display module and the input end of the communication module respectively. After passing the power supply circuit, the power supply falls into two paths, one path supplies power to the humidity acquisition circuit, and the other path supplies power to the probe circuits. The multiple probe circuits are installed in the flue-curing barn.

Description

technical field [0001] The invention relates to the field of tobacco leaf processing, in particular to a humidity monitoring device for a barn. Background technique [0002] In the field of tobacco processing, after fresh tobacco leaves are picked, the tobacco leaves are generally placed in a barn for dehydration. The quality of the dehydration process will directly affect the quality of the manufactured tobacco. In order to be able to precisely control this step, it is necessary to accurately monitor the humidity in the barn during the dehydration process, and then adjust the humidity in the barn according to the monitoring results. [0003] In the existing technology, the humidity in the barn is generally monitored by using a hygrometer + manual method. However, the implementation of this monitoring method requires a special staff member to regularly collect humidity data in the barn, which undoubtedly causes a lot of labor. Waste of resources. [0004] With the continu...
