【Abstract】 At first, boiler water level control system and the mean of alarm and fault detection adopted universally are introduced. Aim at the defect of commonly technique, a new technique of alarm in advance of boiler water level is put forward. This technique adopt the idea of signal catenation and blur control. Alarm in advance and seek out the coming fault. The fault can be repaired before water level beyond the limit. Avoiding water level beyond the limit.更多还原
