摘要
为了实现对液氨储罐这一危险源的远程监控,本文提出了基于西门子S7-200PLC和组态王软件的远程监控方案,通过监控系统的软、硬件设计,实现了氨罐室氨气浓度、液氨罐液位、压力的实时数据显示,数据报表实时记录及查询,报警信息记录及查询,实时曲线显示以及报警短信发送。结果表明,该系统可以很好地实现对液氨储罐的远程监控。
In order to achieve remote monitoring of liquid ammonia storage tank, a major hazard, a plan based on Siemens S7-200PLC and configuration Wang software was proposed in this paper. The software and hardware of the monitoring system were designed, so that the real-time data of ammonia concentration in ammonia tank room, liquid level and pressure of ammonia tank were all displayed. As well, data reports real-time recording and inquiry, alarm information records and inquiry, curve real-time display, and SMS submitting of alarm were all achieved. The results show that this system can well realize remote monitoring of the liquid ammonia tank.
