【Abstract】 A system,which can control the rev in two models,computer control or manual control is introduced.This system can easily be switched to each other by a switch,it is convenient to handle and has a high controling precision.with single-chip to provide the function of invariable pressure injection,using the system for the supervising of slurry injection it makes the injection procedure more safe and credible,and PID program in Single-chip greatly enhances the precession of control.更多还原
