Design and Implementation of an Electronic Control System for Oil-Free Scroll Air Compressor

Based on the introduction of the working principle of oil-free scroll air compressor, the hardware and software design of the electronic control system was given with a core of enhanced 51 SCM. Introduced the temperature sensor net made up of DS18B20, the realization of the AC signal acquisition method using a current transformer, and the man-machine interface consists of the digital tube array assembled by the 74LS595 and the independent type keys. The program of the electronic control system employs the work style of cyclical scan, which was developed by the C language in the Keil platform. The test results showed that the installed electronic control system can be operated reliably and trouble-free work continuously.
