The Design and Implementation of Monitoring System of Flue-Cured Tobacco Barn Based on ARM7

Abstract:

The disadvatages of traditional pattern of flue-cured tobacco are low work efficiency, high system error, and poor quality of tobacco and so on. In order to conquer the above shortcomings, a kind of monitoring system was designed in flue-cured tobacco barn based on ARM7 to implement the automation and intelligentization of flue-cured tobacco. The LPC2103 chip was chosen as the microprocessor of monitoring system. The data of temperature and humidity of barns was collected with the AM2303 sensor. We built the hardware platform based on embedded technology, and developed the corresponding software system for monitoring the control object of flue-cured barn in real-time, for implementing the automation of three stages flue-cured period which is yellowing stage, turning color stage and stem drying stage. The environmental data of flue-cured tobacco barn could be saved by the storage module .The result of testing experiments, which contain three periods of flue-cured tobacco, show that the features of our monitoring system ,which are nice control precision, lower system error, sooner response ,and good stability and so on, could be taken advantages of. The embedded technology of ARM7 could be used to improve the efficiency of flue-cured tobacco to guarantee the quality of tobacco, and cut the cost of labor, meanwhile, it could be applied to all kinds of flue-cured tobacco barns as well.
