SECOO石化聚丙烯装置紧急停车系统的设计

ESD Design of SECOO Petrochemical Polypropylene Unit

介绍HIMA公司H51q紧急停车系统在SECOO石化聚丙烯装置中的应用。与目前主流可编程安全系统相比,H51q是第三代经TUV认证的PES系统,采用四重化冗余自诊断结构,具有双CPU单元,4个同时工作的微处理器,与DeltaV系统采用Modbus协议进行串行通信,系统之间则利用工业级交换机Hirschmann构成安全以太网进行数据传输,从而确保安全系统长时间、高效率运行。详细说明了聚丙烯装置H51q与Deltav的系统结构配置和联锁系统操作界面设计,并以烷基铝配置和卸料装置为例说明联锁逻辑具体实现过程。读者可对H51q与DeifaV系统的联合设计和FAT测试过程有清晰的理解。

H51q is the 3rd generation PES system that has passed TUV authentication. It adopts QMR structure and is equipped with dual CPU and four micro processors which work synchronously, it communicates with DeltaV control system according to MODBUS protocol, while in order to insure system safety and efficient long time operation, Hirschmann switeh is adopted for constructing safe internet transferring inner-data between the same type systems. The system configuration from H51q to DeltaV and design of operating interface are explained to help, helping readers understand the union design of H51q and DeltaV system and FAT testing process.
