Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] look first figure 1 , figure 1 It is a structural schematic diagram of the tobacco curing system control device of the present invention. According to the characteristics of the tobacco curing process flow, the curing process mainly has high requirements on temperature and time, so the temperature control system and the timing system need to work at the same time. By controlling the solid state relay 5 (driven by the relay drive circuit 6) to control the on-off of the power supply of the heat pump unit 4, and then control the supply of hot air passing through the hot air insulation pipe 3 and the exhaust fan 2, and finally achieve the temperature control in the barn 1 the goal of. The two control systems (multi-point temperature measurement control system and timing control system) both use single-chip microcomputer AT89C52 (including...

The invention discloses a heat grading circulation control method of an air energy tobacco curing system and a device thereof. The system combines a multipoint temperature measurement control system and a timing control system; the main program of the multipoint temperature measurement control system comprises a system initialization subprogram and an interrupt service program; the interrupt service program comprises a multipoint temperature detection subprogram, a key scanning subprogram, a temperature display subprogram, a temperature control subprogram and an alarm subprogram; the timing control system adopts a timer T0 to accomplish interrupt; a second chronograph adopts a timer T1 to accomplish interrupt; the main program of the timing control system circularly calls a display subprogram, an alarm subprogram and a keyboard scanning subprogram. The system takes air energy as a heat source, realizes multipoint temperature measurement heat grading cyclic utilization through temperature control and timing systems, accomplishes the control strategy of the whole system, and can realize system air current circulation simulation and circuit simulation of the control systems.
Description
technical field [0001] The invention relates to a tobacco curing production system, in particular to a heat classification cycle control method and a device thereof for an air energy tobacco curing system used for rural tobacco curing. Background technique [0002] Tobacco is a common consumer product in modern society. The output of flue-cured tobacco in China accounts for more than 80% of the total tobacco products. The production of flue-cured tobacco is mainly concentrated in Yunnan, Henan, Guizhou, Shandong and other provinces. The production process of flue-cured tobacco can be roughly divided into three stages: seedling raising, field growth and tobacco leaf curing. Tobacco curing is one of the key links to reflect and determine the quality and production benefits of flue-cured tobacco. It involves the organic cooperation of many factors such as the quality of tobacco leaf harvesting, curing room equipment, curing process and practical experience. Therefore, the cur...
