Control circuit and method applied to opening and closing angle of cold air door of heat pump tobacco curing barn
The invention discloses a control circuit applied to the opening and closing angle of a cold air door of a heat pump tobacco curing barn, which comprises a driving circuit, a measuring circuit and a sampling circuit, and is characterized in that the driving circuit drives an air door blade driving motor to positively/negatively rotate through an instruction of an MCU, and the measuring circuit samples and amplifies the running current of the air door blade driving motor and transmits the running current to the MCU; the sampling circuit is used for sampling the operation current of the air door blade driving motor, and the amplifying circuit is arranged between the sampling resistor R300 and the A/D converter of the MCU and comprises an operation amplifier IC301A, a resistor R301, a resistor R302, a resistor R303, an electrodeless capacitor C307, a diode D300 and a diode D301. The invention further discloses a control method applied to the opening and closing angle of the cold air door of the heat pump tobacco curing barn. By designing the control circuit and method for the opening and closing angle of the cold air door of the heat pump tobacco curing barn, the opening and closing time of the cold air door can be automatically and accurately measured, and accurate control over the opening and closing angle of the cold air door of the heat pump tobacco curing barn is achieved through a special control method.
