SIS 是Safety instrumented system的简称，中文意思是安全仪表系统， 它包括安全联锁系统、紧急停车系统 有毒有害、可燃气体及火灾检测保护系统 等，广泛应用于石油、化工等流程工业中。 安全仪表系统SIS, 用于监视生产装置或独立单元的操作，当生产正常时，SIS处于休眠或静止状态。一旦生产装置或 ...
四、SIS 的安全等级：SIL（安全完整性等级） SIS 的可靠性通过 SIL（Safety Integrity Level，安全完整性等级） 划分，分为 SIL 1 至 SIL 4 四个等级（SIL 4 最高）。等级越高，系统的安全性能越强，发生故障的概率越低。 SIL 等级由 “风险分析” 确定：根据生产过程的危险程度（如介质毒性、爆炸风险 ...
SIS安全仪表，DCS，plc 的区别 PLC programmable logic controller, 通常作为成套设备的控制方案，比如说真空、废水、集装、压缩机等等 自成一个体系的系统。 他们的特点往往是不要求很多的模拟量控制，对数字量控制极为有效、 方便、可靠、经济。通常做为DCS的子站点，便于监视。 ESD emergencyshutdown system ...
SIS网站是否被卸载，引发网友讨论和寻找新的替代平台。
