Digital Air Compressor Control System

Abstract

A digital air compressor control system is for creating a customized air compressor. The system includes microprocessor, power supply, electric sensors and electric valve. In general, digital control system includes four overall components, which may be present in a variety of electric-mechanical formulations. The first component is the microprocessor. It controls the system's or component's action. It receives signals and sends out action commands according to user requirements. Microprocessor directs most every component action. The second component is power control system. Under microprocessor control, the power control system can supply or stop supplying current to electric components allowing accurate functionality. The next component is sensors. They include pressure sensors and temperature sensors. The pressure sensor picks up the pressure data from the control pressure area. The sensor sends the signal to the microprocessor for processing, and issues appropriate commands that the designer programmed or that the user preset. The temperature sensor function is similar to the pressure sensor, one difference is that the signal comes from the control temperature area. The microprocessor receives these signals and sends commands to control power on or off; motor run or stop; valve open or close. Another component is the electric valve. These valves follow the microprocessor command to either open or close to allow the air tank to reach preset pressure. It also releases tube pressure air from the pump to tank.
