摘要
本文通过对大宗气站要求更高可靠性和更高安全性的研究,包括大宗气站N2、H2、O2、HE、AR等气体的监测压力、气体探头报警、流量等数据和报警。设计使用西门子S7-400HPLC冗余系统实现大宗气站监测控制,为大宗气站提供更可靠监测系统。
This paper through the research of requirements of higher reliability and higher security of bulk gas stations, including bulk gasstation N2, H2, O2, HE, AR gas pressure, gas alarmmonitoring probe, flow data and alarm a Siemens S7-400 H PLC redundancy system is designed to realize the bulk gas station monitoring and control. It provides more reliable？monitoring system？for the bulk？gas station.
