Application of computer multi-point continuous monitoring wireless control system in baking of flue-cured tobacco

Abstract

The invention relates to the application of a computer multi-point continuous monitoring wireless control system during curing flue-cured tobacco, which belongs to the technical field of flue-cured tobacco modulating equipment. In the invention, based on the existing computer monitoring and controlling technology and by combining the specific parameters of tobacco flue-curing, a wireless network card is installed on a curing barn controller to receive and send the relevant curing information parameter; a user observation, analysis and commanding system is set up to send out 'processing reference' and 'regulation and control command'. The number of users and a monitoring point are set up randomly as required to automatically convert relative humidity level. In the invention, the computer system combines continuous monitoring and wireless regulation and control to directly measure dry-bulb temperature, relative humidity level and curing time, and completely observe humiture change curveand prior-period conditions of tobacco flue-curing, thus having the advantages that observation range is wide, investment cost is low, operation is easy, labor and time are saved, and the tobacco flue-curing technique is put into practice exactly. The application of the invention is suitable for the model of scale production of modern tobacco agriculture and intensified curing.

Description

Application of computer multi-point continuous monitoring wireless control system in flue-cured tobacco curing Technical field: The invention relates to the application of a computer multi-point continuous monitoring wireless control system in the curing of flue-cured tobacco, which belongs to the technical field of flue-cured tobacco modulation equipment. Background technique: It has been more than 70 years since China has monitored the temperature and humidity of tobacco leaves during the curing process. The traditional wet and dry bulb thermometers have been used in the tobacco leaf curing process for a long, long time. The use of wet and dry bulb thermometers has advantages: it can measure the temperature and moisture content of the air more accurately, and avoid some deviations of human perception. Disadvantages: Baking personnel must witness it with their own eyes, otherwise they cannot know the measurement results, which increases the difficulty of baking personnel ...

AI Technical Summary

Problems solved by technology

Disadvantages: Baking personnel must see it with their own eyes, otherwise they cannot know the measurement results, which increases the difficulty of baking personnel working under high temperature and high humidity conditions; at the same time, the observed wet bulb temperature is relatively abstract, and it is difficult for baking personnel to grasp

During the baking test process, the measurement of the plane temperature difference and vertical temperature difference of the smoke chamber requires monitoring dozens of points, and using electronic fire meters to observe intensively, which wastes manpower, material resources, and financial resources, and the observation operation is very inconvenient. The wet bulb temperature obtained is still relatively abstract, and it is difficult for baking personnel to grasp

More importantly, regardless of the wet and dry bulb thermometer or the electronic fire meter, they are greatly restricted by location and region, and cannot be observed and operated on a national or global scale.

Abroad, the United States, Brazil, Canada, Zimbabwe, and Japan have monitored the temperature and humidity in the tobacco leaf curing process for more than 100 years. However, through the centralized and continuous monitoring of the computer system and wireless control, the direct measurement of the dry bulb temperature and relative humidity has not yet been developed. success

Literature search shows that among the existing baking equipment at home and abroad, there is no baking equipment that can directly measure the dry bulb temperature, relative humidity, and baking time through centralized and continuous monitoring of the computer system and wireless control, and can fully observe the temperature. Humidity change curve, condition of tobacco leaves in the early stage of curing
