Temperature real-time detector for flue-cured tobaccos

Abstract

The invention discloses a temperature real-time detector for flue-cured tobaccos, and the conventional tobacco flue-cured humiture measuring instrument cannot be used for directly measuring the surface temperature of tobaccos, and is poor in measuring accuracy. In the detector, an input end of a tobacco temperature collection and conditioning module is connected with a platinum resistor placed on the tobaccos, and an output end of the tobacco temperature collection and conditioning module is in signal connection with an input end of a singlechip and AD conversion module; a curing barn environment humiture signal acquisition module is used for acquiring environment humiture signals, and an output end of the curing barn environment humiture signal acquisition module is in signal connection with the input end of the singlechip and AD conversion module; a clock module is in signal connection with the input end of the singlechip and AD conversion module; a liquid crystal display module is in signal connection with an output end of the singlechip and AD conversion module; and a memory module, a keyboard input module and an MAX3232 communication module are all in signal connection with the singlechip and AD conversion module. According to the invention, the temperature real-time detector for the flue-cured tobaccos can be used for directly measuring the surface temperature of the flue-cured tobaccos through a contact-type manner, and can monitor the humiture of the curing barn simultaneously, is simple to operate, portable, low in power consumption, and can continuously operate for a long time.

Description

technical field [0001] The invention belongs to the technical field of measurement and measurement, and relates to a real-time detector for flue-cured tobacco leaf temperature. Background technique [0002] Tobacco curing is a key technical link in tobacco production, and the temperature and humidity control in the curing process has a decisive impact on the quality of flue-cured tobacco. According to literature review, at present, more than 90% of tobacco leaves in my country still need to be manually cured in ordinary small barns or intensive barns, and the annual consumption is more than 4 million. Conventional manual curing requires on-site monitoring by the tobacco farmers. Generally, every 2 to 4 hours, it is necessary to check the changes in the tobacco leaves or adjust the temperature and humidity. By using the firepower of the stove and the moisture removal window to adjust, it takes about 130 hours for one roasting time. Tobacco farmers have to repeatedly observe ...

Problems solved by technology

Conventional manual curing requires on-site monitoring by the tobacco farmers. Generally, every 2 to 4 hours, it is necessary to check the changes in the tobacco leaves or adjust the temperature and humidity. By using the firepower of the stove and the moisture removal window to adjust, it takes about 130 hours for one roasting time. Tobacco farmers have to repeatedly observe or adjust the temperature and humidity about 50 times, an average of nearly 10 times a day. Therefore, baking is labor-intensive and risky. The temperature and humidity in the curing room cannot be accurately controlled, and baking errors are prone to occur, resulting in poor baking quality. unstable

[0003] In recent years, under the policy guidance of the State Tobacco Monopoly Administration, various tobacco companies, scientific research institutes and some enterprises have transferred a large amount of scientific research power to the research and development and promotion of curing room equipment, some of which are used to monitor the temperature and humidity of the curing room Instruments emerged as the times require. These instruments indirectly infer the curing state of the flue-cured tobacco by directly monitoring the temperature and humidity of the curing room. In the end, it is still necessary to manually observe the dehydration state of the tobacco leaves to control the curing process, and the curing accuracy is low.
