step S42: if yes, directly taking the set grade description object as a corresponding fault item;
step S43: if not, searching a possible set grade description object corresponding to the grade keyword, determining a selection item of an activity target according to the possible set grade description object and the grade keyword, judging whether the selection item is contained in a fault item, if not, directly judging that the routing description information is not in the safety grade range of the monitoring information, and if so, taking the selection item contained in the fault item as the corresponding fault item;
Step S44: and identifying fault attributes of the corresponding fault items, and matching a safety level range according to the fault attributes. In the first case, the fault attribute corresponds to a rank keyword; in the second case, the fault attribute may be derived from matching of the possible setting grade description object, for example, the indication of the transformer area is abnormal, but it is identified that the possible setting grade description object includes a transformer and a measuring instrument, so that the indication is determined to be abnormal, and in addition, the fault attribute may be determined by the attribute description of the selection item by the activity target, which is equivalent to refinement grade keywords; the security level range matched according to the fault attribute may be abnormal, normal, uncertain or object in doubt, for example, the uncertainty or object in doubt should be attributed to the range of possible abnormality, and the normal belongs to the range of no abnormality and good work.
When the embodiment is applied, the name keyword is mainly used for describing an object contained in a power transformation area, and the name keyword can be a certain power transformation area or a certain specific object, such as a partition switch in primary equipment; the level keywords are mainly used for describing the states of the objects, such as perfect, normal, possibly abnormal, fault and the like; when detecting the inspection description information, the inspection is mainly performed by setting a grade description object, so that the inspection can be specific to an object below the grade of the power transformation area; when the generic object of the level keyword is not the set level description object, the possible set level description object corresponding to the level keyword is automatically identified, the possible set level description object is displayed, the selection item of the possible set level description object is selected according to the activity target, and the selection item contained in the fault item is used as the corresponding fault item, so that the fault item can be sourced from two ways, and the use scenario is widened conveniently according to the determination of the safety level range.
