Embodiment

[0038] Example: Take STC89C52 microcontroller as the core, and connect SHT10 digital sensor to the I / O port as the temperature and humidity signal acquisition part; I 2 The C port is connected to the FM3130 chip, which is used as a real-time clock (RTC) and FRAM non-volatile memory; the serial port is connected to the TC35 module, which will send a text message to alarm when the system is abnormal; the liquid crystal module adopts the HB19264M1 liquid crystal module of Shenzhen Haibin Company.

[0039]Among them, the 64K ferroelectric non-volatile RAM function of the FM3130 chip is used as a data storage part. It has the function of automatically saving data when power off, which can be written indefinitely; it also has a real-time clock / calendar function, which can provide a system for the single-chip microcomputer. Time, which plays a role in simplifying the hardware structure and reducing costs.

[0040] The system normally displays the real-time data in the barn, including...

Abstract

The invention relates to a digitized monitoring system for tobacco baking, which consists of a single chip, a display module, a memory module, a short message module, a humiture detection module and a weight detection module. The system uses the single chip as a core to connect each corresponding module, wherein an I / O port is externally connected with the humiture detection module, an IC port is connected with the memory module, and a serial port is connected with the short message module. The system can monitor humiture of a curing barn and moisture content variation of the tobacco in real time, provides real-time data for tobacco baking, reasonably controls water loss speed and water loss of different temperature sections during baking, increases and improves inherent quality of the tobacco, and improves the quality of the tobacco.

Description

technical field [0001] The invention relates to the technical fields of agricultural production and processing, in particular to a real-time monitoring of the moisture content of tobacco leaves in a curing process, and a remote control system for the temperature and humidity of a curing room and the moisture content of tobacco leaves. Background technique [0002] During the curing process of tobacco leaves, the detection of temperature and humidity in the curing room and the detection of moisture content of tobacco leaves are very important to control the quality of tobacco leaves. [0003] At present, there are more than ten patents related to the intelligent control of tobacco leaf curing: "Tobacco Leaf Curing Intelligent Control Device" (CN200966307), "Tobacco Leaf Curing Service Guidance Instrument" (CN2744179), "Intelligent Tobacco Leaf Curing Instrument and Tobacco Leaf Curing System" (CN200959818), "Tobacco Leaf Curing Whole Process Automatic Control Device" (CN20096...
