Influence degree, specific manifestation are as follows: get changed power difference P, thickness of insulating layer reduction degree L, actual difference m it is absolute
Value, and three absolute values are added to obtain mutation data Yb.
4. a kind of electric power safety monitoring system based on data acquisition according to claim 1, which is characterized in that the peace
The specific operation process of security evaluation operation in full evaluation module are as follows:
Step 1: security evaluation module show that changed power difference P carries out safe judgement according to above-mentioned, specifically:
S1: as P≤X1, then determine that the connecting line is intact；
S2: as P > X1, then determine that the internal power of the connecting line is greater than power required for power equipment, the connection line loss
It is bad, it needs to replace connecting line in time, generates connecting line and damage signal, X1 is the power equipment power preset value；
Step 2: security evaluation module carries out safe judgement according to above-mentioned thickness of insulating layer reduction degree L, specifically:
S1: as L≤X2, then the insulating layer reduction degree of the connecting line is determined without departing from safe range, connecting line is intact；
S2: as L > X2, then the insulating layer reduction degree of the connecting line is determined beyond safe range, the insulating layer on connecting line surface damages
It is bad, staff can be damaged, generate connection line insulating layer and damage signal, X2 is the insulating layer preset value of the connecting line；
Step 3: security evaluation module carries out safe judgement according to mutation data Yb obtained above, specifically:
S1: as Yb≤X3, then determine that the anomalies of the connecting line are small, belong in safe range；
S2: as Yb > X3, then determining that the anomalies of the connecting line are big, exceeds safe range, and there are security risks, generates different
Varying signal, X3 are the anomalies preset value of the connecting line.
