| This thesis studied the YanKuang GuoTai power supply of the air separation device, With many years of experience in automation, the design of its automation system is carried out.In air separation plant air separation process, there is a lot of equipment and piping, control system needs to have the function of data acquisition, recording and automatic control. Currently YanKuang GuoTai company plans a new air separation unit. In design work, using Yankuang Cathay many years of accumulated experience, lead to the air separation plant automation design more suitable for Yan Kuang GuoTai field application. The new method is to realize the automatic management and control of the process parameters through the idea of software engineering, so as to realize the automatic record, the instruction, the control, the alarm and the interlocking function of the process parameters. Production engineer can track the operation situation, control situation and potential production problems of the process flow of all air separation operations, make sure to call history and view the historical production process as needed. Firstly, the function of the software of the air separation unit is analyzed, then, the process management function of the air separation unit, the measurement and control function of the process parameters, data management functions and so on are analyzed, the main software functions of the system are discussed. System software design is based on B/S architecture, remote users can access the system data through the browser, which is convenient to use, and is conducive to maintenance.The system commissioning has been underway for a period of time, the operation indexes showed that The automatic control system of the air separation unit has basically achieved the expected development goals, greatly improved the ease of use, safety and production efficiency of the air separation unit of the automatic control system of the air separation unit. |
