ABSTRACT
This design make use of the single slice the machine to control from a distance the system to realize to control electric motor. Detailed treatise single slice this design for total project for machine controlling the system, hardware design, software and dependable analysis etc. The main parts for using of this system is a machine of single slice 89 C51s, FSK shoot the slice the many piece of nRF401 etc. That system has to automate the degree high, the cost is low, and the physical volume is small, control precision etc. advantage, consumedly increased the product rate of production, and have the good and economic
performance with the amplitude's development foreground.

Keywords: Machine of single slice; remote control; receive; control electric machinery
