Abstract: An error detecting device for detecting failure of a hierarchical system comprises a detected signal receiving interface and a processor. The detected signal receiving interface receives a parent failure event occurring in the hierarchical system. If the processor diagnoses that the parent failure event is in a failure state, the detected signal receiving interface receives a first child failure event occurring in the hierarchical system. If the processor diagnoses that the parent failure event is not in the failure state, the detected signal receiving interface receives a second child failure event occurring in the hierarchical system. The parent failure event depends on the first child failure event. The second child failure event depends on the parent failure event. The processor sequentially diagnoses until the detected signal receiving interface receives one of the failure events at a bottom level in a binary search tree structure.

It also has good anti-pollution properties. The preparation method of the invention can be easily integrated into the existing semipermeable membrane production line without further cost input which has far-reaching practical significance and commercial value.
