The RF(Radio Frequency) Control System of BEPC(Beijing Electron Position Collider) has been improved in Aug. 1994. The design of the new system uses intelligent chips as core controllers which deal with signal of the RF System. PLC(Programmable Logic Control) technique is also adopted in this system; it serves as the key instrument of signal interlock. This paper describes the method and the upgrading procedure of this system.
