摘　　要：针对铝冶炼企业沉降槽耙机负荷报警装置已不能达到实时监控的实际问题,设计了一套基于西门子公司S7-200 PLC在线微机监测报警系统。介绍了系统硬件组成、PLC控制程序的编制以及监控界面设计。该系统实现了同时在线监测2个烧结法分离沉降槽的耙机负荷,有效提高了设备的运转效率。实践证明,该系统稳定可靠,响应快,精度高。Because the alarm device of raker load has not been able to achieve the moni- toring of the real-time performance in aluminum smelting enterprises, the online monitor- ing and alarming system based on Siemens S7-200PLC is developed. The hardware components, PLC control programs and moniioring interface of the system are introduced. The system realizes that the raker load of two sintering process separation subsiders are online monitored at the same time, and enhances the operating efficiency of the equipment. The practice shows that the system has merits of good stability, prompt response speed and high precision.
