The configuration controller applied in the greenhouse monitoring and control combined with progressive linear variables in a greenhouse

摘要

"Configuration applied in controller of greenhouse monitoring and control in conjunction with progressive linear variables in a greenhouse.The present application of invention patent, consists in a device (1) (Figures 1 and 2) with characteristics of electronic, mechanical, and logical, connected to an oven (Figure 3).Of tobacco curing and drying, forced ventilation or not, to control and monitor the temperature and atmospheric condition in the interior of said oven (Figure 3).With the processor (5) uses a mathematical method PID (proportional, integral and derivative) to control the on-off type drives (not continuous)Being in charge of two main tasks: (a) through the fan of the furnace (not illustrated) provide in the chamber of the greenhouse (Figure 3) a temperature.Determined by the operator or by the program and the required at various stages of curing or drying.Dry bulb as constant as possible; (b) through the control of the engine of the flap admissor (6) of air from the oven (Figure 3).To provide a relative humidity within the same as constant as possible; translated by a wet bulb temperature (3) which is determined by the operator or by the program during the stages of healingOr drying of material in its interior; an alarm intelligent ", whose buzzer (Sirene) is muted by the operation button (8) reactivated when the temperature returns to the limits.With the reactivation manual, and in the models configured for fan of furnace (not illustrated), the same operation button (8) to turn off and allows the reactivation thereof, if desired.Keeping the buzzer silenced or dismissed, the reactivation, the programming of the processor (5) that activates the automatically;
