The BEPC(Beijing Electron‐Positron Collider) is upgraded to be BEPCII, a two‐ring Electron‐Positron collider. Due to the construction of the BEPCII and upgrade of the existing front ends and beamlines, all the existing EPSs(Equipment Protection Systems) have to be redesigned and reconstructed at BSRF. All the redesigned EPSs for the upgrading front ends and beamlines are a PLC‐ and SCADA‐based equipment protection and control and monitoring system. The EPSs are used to protect BEPCII two storage rings vacuum against vacuum failures in a beamline, as well as to protect the front‐end and beamline components from being damaged by synchrotron radiation. For the high‐power wiggler beam lines, a fast movable mask is used to protect the blade of a fast‐closing valve from damage when the fast‐closing valve is triggered to close, which does not need to dump the electron beam running in BEPCII outer ring. In addition, all redesigned PLC‐ based EPSs are used to communicate with the same centralized monitoring comput...
