Abstract
Science and technology are advancing rapidly today, and the development of productive forces, wireless, long-range, precision, small, Intelligent technology guides the direction of development.Air compressor as an important form of energy have been widely used in the production of all aspects of life. In particular, twin-screw-type air compressor is widely used in mechanical, metallurgical, power electronics, pharmaceuticals, packaging, chemicals, food, mining, textiles, transport, and other industrial fields, compressed air into the mainstream products air compressor, is to A standard atmospheric pressure of air through the transformation of the mode of energy output to meet the needs of users of air equipment, energy conversion generally be interpreted as mechanical energy to kinetic energy.
The system is using technology developed by PIC microcontroller dedicated controller. The use of pressure sensors, temperature sensors and external circuit together constitute a can of compressed gas to control the smart instrumentation. Users can set the parameters of the control console launch air compressor, pressure protection, monitoring different parts of the system of running state, when the anomaly occurred when the alarm signal or shutdown protection. Upon completion of the system to control the compressed air at the same time, its parameters through the liquid crystal display panels, interactive form of human interface. The whole system can be divided into pressure signal acquisition module, the temperature signal acquisition module, keyboard module, modules and PC communications module of five parts.
