【摘要】：本文论述了硝酸装置四合一透平机组在线监测系统的重要意义,分析了在线监测系统的国内外研究现状和发展趋势。并通过对四合一透平机组在硝酸装置中作用的分析,完成对在线系统信号采集方案、系统功能、系统硬件配置、机组安全保护策略及通讯网络结构的设计。通过对电涡流传感器的工作原理、测量电路的分析,开发了新型电涡流传感器的结构和信号处理电路,并完成了对其的静态测试。系统采用本特利3500系统完成对振动、位移、转速等机组状态检测信号的采集和处理,并通过MODBUS协议与系统主控制模块ICS T6300实现数据通讯。本文通过对机组故障诊断技术的研究,以S8000故障诊断系统为硬件基础,实现了系统四合一透平机组故障分析、诊断和远程监测功能。最后,分别通过IEC 1131toolset软件开发平台和Intouch 10.1HMI组态软件完成对系统数据转换、报警、安全保护联锁程序和人机界面的开发,并通过软件的离线模拟功能完成对程序的离线测试。
[Abstract]:This paper discusses the important significance of nitric acid unit four in one turbine unit on-line monitoring system, analysis of the online monitoring system of domestic and foreign research present situation and development trend. And through the analysis of the effect of four in one turbine unit in nitric acid unit, the completion of the online signal acquisition system scheme, system function, hardware configuration, design protection strategy and communication network security unit. The working principle of the eddy current sensor, measurement circuit, signal processing circuit structure and the development of a new type of eddy current sensor, and completed the static test. The system of vibration displacement, using the Bentley 3500 system, the acquisition and processing of state speed detection unit the signal, through the MODBUS protocol and the main control module ICS T6300 to realize data communication. Based on the research of the fault diagnosis technology of the unit, to S8000 fault The diagnosis system for basic hardware, realizes the system four in one turbine generator fault analysis, diagnosis and remote monitoring function. Finally, through the IEC 1131toolset software development platform and Intouch 10.1HMI configuration software to complete alarm system development, data conversion, safety interlock protection program and human-computer interface, and complete the program through the off-line test offline software function simulation.
