摘要:
本文阐述了SRP/CS性能评估流程,确定了采用基于危险的方法确定SRP/CS要求的安全性能等级(PLr),介绍了SRP/CS控制回路的类别、平均危险失效时间(MTTFd)、平均危险失效的诊断覆盖率(DCavg)及共因失效(CCF)四个参数的确定方法,并对数控车床可移动式防护门控制系统进行了性能评估。
Process of performance evaluation of safety-related part of a control system (SRP/CS) was reported. Required performance level (PLr) of SRP/CS was determined by hazard based approach. Determined methods for category of SRP/CS, MTTFd, DCavg and CCF were reported. Performance evaluation was taken for control system of movable guard of CNC lathe.
