The invention provides an intelligent fault diagnosis method and system for a crane, and the method comprises the steps: S1, initializing a flag bit of a fault data set, and collecting all flag bit data; the flag bit data is flag bit bytes; s2, classifying the flag bit data into a flag bit data group; collecting fault data, and classifying and summarizing the fault data to a fault data group based on the flag bit data; the fault data is Data data; s3, performing logical operation based on the fault data set and the flag bit data set to obtain a diagnosis result; s4, the diagnosis result is sent to a CMS, and then fault alarm is achieved; the CMS is a content management system. According to the method, logic correlation operation can be carried out on the faults, the source nodes where the faults occur can be directly checked out, interference item faults are shielded, then the crane fault checking speed is greatly increased, and the maintenance time of the crane is effectively shortened.

    本发明提供了一种起重机智能化故障诊断方法和系统,包括:步骤S1:初始化故障数据组的标志位,并且采集所有标志位数据;所述标志位数据,即标志位字节;步骤S2:分类所述标志位数据至标志位数据组;采集故障数据,基于所述标志位数据,分类汇总至故障数据组;所述故障数据,即Data数据;步骤S3:基于所述故障数据组与所述标志位数据组进行逻辑运算,得到诊断结果;步骤S4:将所述诊断结果发送至CMS,进而实现故障报警;所述CMS即内容管理系统。本发明能够对发生的故障进行逻辑相关性运算,直接排查出故障发生的源发节点,屏蔽干扰项故障,进而大幅度提高起重机故障排查速度,有效降低了起重机的维护时间。
