摘 要:为提升工程控制系统的可持续运行能力,应对系统发生故障的实时定位与排查,提出自适应算法,以探究水利工程自动化控制系统故障排除方法。利用传感器与执行器进行系统故障数据传输,按照能量尺度对故障信号进行分解,将分解后的数据值整理成集合,作为系统在初始化的故障信号;识别系统发生故障类型,采用稀疏分离处理的方式,按照其频谱的偏移程度,对故障信号进行局部处理,掌握系统发生故障中不同信号的类型;使用系统训练样本建立对应的故障矩阵,按照时延及时调整指令执行顺序与时间,执行故障排除指令。同时设计实验,检验提出的故障排除方法在实际应用中可实现对系统发生故障信号的有效排除。结果表明,相比传统故障排除方法,效果更为显著。In order to improve the sustainable operation ability of engineering control system,real-time location and troubleshooting of system faults should be dealt with.Therefore,this paper explores the troubleshooting method of hydraulic engineering automation control system.An adaptive algorithm is proposed,which uses sensors and actuators to transmit system fault data,decomposes the fault signal according to the energy scale,and arranges the decomposed data values into a set as the initial fault signal of the system.The fault type of the system is identified,and the fault signal is processed locally according to the spectrum offset degree to master the types of different signals in the system failure.The system training samples are used to establish the corresponding fault matrix,and the order and time of instruction execution are adjusted in time according to the time delay,and the troubleshooting instructions are executed.Experiments are designed to verify that the proposed troubleshooting method can effectively eliminate the fault signal of the system in practical application,and the effect is more significant than the traditional troubleshooting method.
