Description

Curing barn with dark environment shooting light supplementing system

Technical Field

The utility model relates to a flue-cured tobacco technology control technical field, concretely relates to roast room with dark ring border light filling system of shooing.

Background

The tobacco flue-curing house is essential basic equipment in the production of flue-cured tobacco. The tobacco leaves are cured and modulated internally, and then the special color, fragrance, taste and shape of the cured tobacco are shown, so that the cured tobacco becomes a high-quality raw material meeting the requirements of the cigarette industry.

The quality of the tobacco leaves mainly depends on the control of a flue-cured master on the temperature and the humidity in the baking process of the tobacco leaves, and the control of the temperature and the humidity by the flue-cured master is usually based on the appearance and morphological characteristics of the tobacco leaves in a tobacco flue-curing house; because two very obvious changes of the appearance of the tobacco leaves occur during the baking process: firstly, the color of the tobacco leaves changes from yellow green to yellow, and if the control is wrong, the tobacco leaves can continue to develop into brown and dark brown; secondly, the tobacco leaves are changed from an expansion state with the moisture content of 80-90 percent into withering and withering till being dry (the moisture content of the tobacco leaves is 5-6 percent, and the moisture content of the main vein is 7-8 percent).

Therefore, when the tobacco leaves are baked, images in the baking process need to be acquired, the conventional image acquisition device is generally fixedly arranged, and when images at other angles and heights need to be acquired in the next tobacco leaf baking process, the images need to be disassembled and assembled again and the positions need to be adjusted, so that the operation is complex and the use is inconvenient; chinese patent CN209746419U provides a flue-curing barn video remote monitoring system based on tracking dolly, carry the camera through the tracking dolly and remove along the orbit in the flue-curing barn, control the tracking dolly and the tobacco leaf circumstances of toasting in the remote observation flue-curing barn through remote terminal, but this patent can only observe the tobacco leaf of bottom layer flue-curing tobacco frame in the flue-curing barn, it hangs the tobacco leaf of eminence in the flue-curing barn to be difficult to observe, and tracking dolly electronic equipment is more, complicated humiture environment has very big influence to the tracking dolly in the flue-curing barn.
