摘　　要：针对煤制油尾气制氢装置系统中温度、压力控制较复杂的情况,设计开发了基于S7-300PLC的控制系统。在该系统中,PLC通过PROFIBUS-DP通讯协议和模糊PID控制方法实现空压机的变频调速以保证尾气制氢装置反应温度的稳定;应用WinCC组态软件实现上位机对反应过程的实时监控和远程控制;利用SQL Server 2005软件实现数据的存储和编制报表。Focusing on the complex control condition of temperature and pressure,it develops a new control system based on S7-300 PLC. It uses the frequency conversion of air compressor to control temperatuer with communication protocol of PROFIBUS-DP,takes fuzzy-PID control theory to keep the temperature of hydrogen manufacturing unit stable,applies WinCC configuration software to achieve real time monitoring and remote control of the process. In addition,it uses SQLServer 2005 and other software to develop date storage and report. The application shows that this control system is simple,flexible,convenient and practical.
