摘　　要：针对余热利用系统仪表多,要求数据准确,控制精度高的特点,烧结余热利用控制系统采用连锁控制,即把关键数据作为可控对象,通过参数比较选择导通路径,实时调节控制程序;对关键设备进行并行控制,在信号处理和管理上采用冗余技术,进行设备故障诊断和无扰动切换,防止数据发生振荡或飘移,减少了故障停机时间。Pointing at the characteristics that there are many instruments in the waste heat utilization system, the data must be exact and high control precision, interlock control and redundancy technology were adopted in sintering waste heat utilization control system, that is, making key data as controllable object, selecting the run way by the parameter comparison and real-time adjusting control program; parallel controlling the key equipment, adopting redundancy technology in signal processing and management for the equipment fault diagnosis and undisturbed switching and to prevent the data surge and drift. Then it reduced downtime.
