Description
Technical field
The utility model relates to air compressor, relates in particular to the electronic control system of air compressor.
Background technique
Controlling component on the conventional air compressor mainly is pressure switch and pressure gauge, and pressure switch can be controlled automatically by air pressure, also can artificially control with hand push button.When the gas holder internal air pressure was elevated to the predefined shutdown pressure of pressure switch, switch was with regard to automatic disconnection, and air compressor is carried out autostop (shutting down as 8bar); When the gas holder internal air pressure was reduced to predefined start pressure, pressure switch was just connected automatically, and air compressor is carried out Auto Power On (as the 6bar start).The air pressure that can keep air compressor to export like this can be in normal operating range.The setting of pressure is that the adjusting screw rod preloading spring in the depended on pressure switch is adjusted, but this regulative mode not only precision is not enough, also can answer the distortion of spring and cause the pressure that stops, starts shooting to depart from setting value.
In addition, the pressure of conventional air compressor shows by pressure gauge.Pressure gauge has two, and one shows the pressure in the gas holder, and another shows the pressure of relief opening.Traditional pressure gauge is pointer, and metric system (bar) and (psi) two kinds of units made in Great Britain are arranged on the dial plate, though can distinguish unit system by the color of scale, is not intuitively after all.Simultaneously, the indicator shake often makes not readability standard of indicating value when using because of user's visual angle deviation and air compressor, also is difficult to see clearly in the indicating value of the bad environment downforce table of light.In addition, traditional too mechanization of air compressor control system, not too suitable to the mini air compressor that is used for family.
Summary of the invention
Adjust not accurate enough in order to solve above-mentioned traditional air compressor pressure, cause the pressure that stops, starts shooting to depart from easily, pressure gauge numerical value and pressure unit corresponding relation are not directly perceived, and indicating value shows unsharp technological deficiency, and the purpose of this utility model provides and a kind ofly adjusts accurately, the air compressor electronic control system of liquid crystal digital display.
To achieve the above object, the utility model has adopted following technological scheme:
The electronic control system of air compressor, comprise following unit: power supply unit, pressure acquisition unit, signal amplification unit, human-computer dialogue unit, central processing unit (CPU), electric-motor drive unit, liquid crystal drive unit and liquid crystal screen, pressure acquisition unit comprises the pressure transducer of the pressure of two difference collecting unit air compressor gas holder and relief opening, pressure acquisition unit links to each other with signal amplification unit, signal amplification unit links to each other with central processing unit (CPU), central processing unit (CPU) connects electric-motor drive unit and liquid crystal drive unit respectively, and the liquid crystal drive unit connects liquid crystal screen.
The electronic control system of above-mentioned air compressor also is included as liquid crystal screen LCD backlight backlight is provided, and LCD backlight is connected with central processing unit (CPU).
Above-mentioned human-computer dialogue unit comprises power knob and pressure unit selector button.Power knob, but the break-make of manually-operable control motor power; Pressure unit selector button, but the unit of selection pressure (bar or psi).
Above-mentioned power supply unit is the unit that ABAP Adapter step-down, rectification, filtering, voltage stabilizing is formed electronic control plate power supply.
Pressure acquisition unit of the present utility model is gathered the pressure of gas holder and the operating air pressure of relief opening respectively with two pressure transducers, and is converted into electrical signal.Signal amplification unit amplifies electric pressure signal, so that the central processing unit (CPU) computing.Central processing unit (CPU) is by programmed settings autostop pressure, Auto Power On pressure; set getting in touch of manual power button and electric-motor drive unit; the conversion of setting pressure signal and LCD signal, the getting in touch of setting pressure unit's selector button and liquid crystal drive unit.The liquid crystal drive unit is used to drive liquid crystal screen, makes liquid crystal screen show relevant information.LCD backlight makes visual effect better for liquid crystal screen provides backlight.Electric-motor drive unit is stressed and gathers and the dual control of power knob provides power supply to the air compressor motor.
The utility model makes air compressor hommization more, electrification of domestic.It becomes the pressure gauge of mechanical pointer into liquid crystal digit-display manometer, represents the gas holder internal air pressure with the gas holder pattern, represents relief opening air pressure with the pneumatic tool pattern; Metric system and pressure unit and reading made in Great Britain can switch by the pressure unit selector button as required; Liquid crystal screen is provided with backlight, and dark place also can see the indicating value of pressure clearly.Pressure control is to gather pressure signal by pressure transducer; and be converted into electrical signal; by the central processing unit (CPU) computing; on the one hand the pressure indicating value is shown in liquid crystal screen; realize autostop and start by the shutdown pressure and the start pressure control motor driver element that configure on the other hand; pressure is set accurately, and indicating value is clear.Also be provided with power knob on the electronic control plate, can manually control the shutdown and the start of air compressor according to user's needs.
