8. system according to claim 7, it is characterised in that the judge module, being additionally operable to ought be while meets following bar During part, confirm the zero live wire spark phenomenon as caused by electric wire aging occur in use electrical circuit to be measured:
ipk>Ist
ΔIr-n/ΔTr-n<Δir/Δtr<ΔIr-x/ΔTr-x
ΔIf-n/ΔTf-n<Δif/Δtf<ΔIf-x/ΔTf-x
tpk>Tst
Wherein, ipk:The peak values in real time electric current of use electrical circuit to be measured, Ist:When zero live wire is struck sparks, minimum peak point current;Δir/Δ tr:The rate of rise of real-time surge peak point current, Δ I in use electrical circuit to be measuredr-n/ΔTr-n:When zero live wire is struck sparks, transient current The minimum rate of rise, Δ Ir-x/ΔTr-x:When zero live wire is struck sparks, the maximum rate of rise of transient current;Δif/Δtf:Loop In surge peak point current in real time descending slope, Δ If-n/ΔTf-n:When zero live wire is struck sparks, the minimum descending slope of transient current, ΔIf-x/ΔTf-x:When zero live wire is struck sparks, the maximum descending slope of transient current;tpk:When real-time surge current is maintained in loop Between, Tst:When zero live wire is struck sparks, the minimum of sparking electric current is held time.
9. system according to claim 8, it is characterised in that the electric wire aging sparking model is also beaten based on electric wire aging When fiery, the gross energy in the generating period of surge current is too high and triggers obtained by the analysis of fire;
The judge module, is additionally operable to when further also meeting following condition, confirms occur in use electrical circuit to be measured by electric wire Zero live wire spark phenomenon caused by aging:
Q*Wpk>Wst
Wherein, Q:It is to be measured with occurring surge current number of times, W in electrical circuit within the same sparking event judgement cyclepk:Surge electricity It is to be measured with the real-time gross energy powered in electrical circuit, W in the generating period of streamst:When zero live wire is struck sparks, the minimum struck sparks each time Energy.
10. the system according to claim any one of 6-9, it is characterised in that also include:
Study module is corrected, for according to feedback of the user to fire alarm judged result, and machine learning, constantly amendment is combined The electric wire aging sparking model.
