炼厂罐区废气治理装置远程监控系统设计

介绍了以工控机、PLC以及控制设备和检测仪表所组成的炼油厂罐区油气回收自动监控系统。工控机通过组态王软件进行组态,PLC作为现场控制单元,配合各种检测设备对油气回收装置中的工艺参数进行采集,实时监测废气处理过程与设备运行状态,并对现场调节阀和动设备进行相应控制。同时,利用现场总线进行数据交换,完成整套装置的自动监控与管理。从监控结果中可知,PLC与上位机之间数据传送可靠稳定、操作简单,提高了炼油厂的监控和管理水平。

Design of Remote Monitoring System for Waste Gas Treatment Unit in Refinery Tank Area

The automatic monitoring system for oil and gas recovery unit in refinery tank area was introduced, the system included industrial computers, PLC and control equipments and detection instruments. Industrial computer works through kingview configuration software;PLC as the control unit collects the technological parameters of equipments for oil and gas recovery, monitors the gas treatment process and equipment running status, and controls the valve and dynamic equipments. At the same time, the system uses the fieldbus to exchange data, and the system completes automatic monitoring and management of the unit. The monitoring results show that the data transmission between the PLC and the upper machine is stable and reliable, the system improves the monitoring and management level of the oil refinery.
