Research And Implementation Of Small Air Compressor Control System

Air compressor is the main gas source device, from the energy point of view, thecompressor will belong to the machine that the motive of the prime mover energy into gaspressure energy.With the development of science and technology,the use of the pressureenergy is more and more widely,which makes the compressor has become one of the keyequipment is essential in many sectors of the national economy construction. While the smallair compressor has the advantages of high efficiency and energy saving, safety andenvironmental protection, low noise, small size, light weight, simple structure, strong mobilityand adaptability.widely used in the fields of medical equipment, automotive industry, foodpreservation, beauty care, environmental monitoring etc.Small air compressor existing mainly by mechanical means to regulate intake valve, cannot be continuous supply and demand on the regulation of air supply, when the gasconsumption changes, the air pressure will become unstable and fluctuate. In order to satisfythe performance of air compressor various real-time detection, the small air compressorcontrol system which uses a single chip and intelligent control technology is a kind ofintelligent.Research background and significance of the paper summarizes the function of small aircompressor, introduces the current research situation of air compressor and its realization, Onthis basis, puts forward the design scheme of air compressor, and the corresponding parametermeasurement principle and method, set up the hardware circuit.Taking C8051F340as thecontrol core, power CS5463and DS18B20of the motor current, voltage, temperaturemeasurement and, to prevent voltage, current is too large, to prevent the motor temperature istoo high, to protect the motor; External humidity sensor DHT11to collect air humidity value,the outside air humidity value of water more and more high compressed air out, whichrequires the drainage, to ensure that the gas tank has the space to store enough compressed air;Additional collection tank pressure sensor and the pressure in the following output pressureand output valve, stepper motor is used to regulate the output pressure; With touch screencolor LCD interface circuit. According to the hardware platform, and puts forward the overalldesign scheme of the software system, and gives the program design process and part of eachmodule code.
