Abstract

The embodiment of the invention discloses a control method of an air compressor and the air compressor. The air compressor comprises a motor, a threaded rod, a motor drive chip, a spring, an internalpressure adjusting device and a control unit. The motor drive chip is used for driving the motor to drive the threaded rod to move. The threaded rod moves to compress the spring so that the internal pressure adjusting device can be driven to move to achieve pressure adjustment. The method comprises the steps that an outage signal of an external power supply source of the control unit is detected in real time; a power supply source of the motor drive chip is turned off according to the outage signal; the motor drive chip is powered through an energy storage element; and after the power supply source of the motor drive chip is turned off, during the period when the energy storage element is discharged, relative data of a compression position of the spring and a preset reference point when the pressure is adjusted last time is saved. By means of the scheme, a power down state is automatically acquired when the air compressor is abnormally powered off, enough duration is reserved for information preservation, the situation that parameters are adjusted again every time when power is off, and convenience is provided for an operator.

Description

technical field [0001] Embodiments of the present invention relate to air compressor control technology, especially to an air compressor control method and an air compressor. Background technique [0002] In existing technical implementation schemes, such as figure 1 As shown, when the air compressor is adjusting the pressure, the control program drives the stepper motor to drive the adjustment screw to rotate, and the screw rotates to compress the pressure regulating spring, so that the internal pressure regulating device adjusts the pressure to a balanced value. The air compressor control unit finally records and saves a spring compression value relative to the reference point in the memory. When the air compressor is started next time, the screw can be automatically adjusted to the last design position relative to the reference point (that is, the air pressure setting Value). [0003] However, for the above solution, once the system is abnormally powered off, since the ...
